Oranges are a popular fruit enjoyed by many around the world,and their harvest is an important aspect of agriculture.Heres a detailed composition on the topic of picking oranges:Title:The Harvest of OrangesIntroduction:Oranges,with their vibrant color and sweet taste,are a staple in many diets.They are not only a source of vitamin C but also a symbol of health and vitality.The process of picking oranges is a delicate and laborintensive task that requires care and precision.The Season for Harvesting:Oranges typically ripen in the late fall and winter months,depending on the variety and the climate of the region.The harvest season begins when the oranges reach their peak color and sweetness.Farmers closely monitor the fruit to determine the optimal time for picking.Preparation for Harvest:Before the actual picking begins,farmers prepare the orchard by pruning any dead or diseased branches.This ensures that the trees are healthy and that the fruit can be easily accessed.Additionally,the ground beneath the trees is often cleared to facilitate the movement of workers and equipment.The Art of Picking Oranges:Picking oranges is a skill that requires patience and a gentle touch.Workers use longhandled clippers to reach the high branches without damaging the fruit.Each orange is carefully cut from the branch,ensuring that the stem remains intact.This helps to preserve the fruits freshness and prevents it from bruising.Sorting and Packing:Once picked,the oranges are sorted by size and quality.Damaged or underripe fruit is set aside and not included in the final product.The good quality oranges are then packed into boxes or crates,ready for transportation to markets or processing facilities. Challenges in Harvesting:Harvesting oranges can be challenging due to factors such as weather conditions,labor shortages,and market fluctuations.Adverse weather,like heavy rain or frost,can damage the fruit and reduce the harvest yield.Additionally,the laborintensive nature of the taskmeans that finding enough workers during peak harvest times can be difficult. Technological Advancements:To address some of these challenges,technology has been introduced to the harvesting process.Some farms now use machines that can shake the trees gently,causing the ripe oranges to fall into a collection area.This method can increase efficiency and reduce the physical strain on workers.Conclusion:The harvest of oranges is a critical part of the agricultural cycle,and it involves a series of careful steps to ensure the fruit is picked at the right time and in the best condition. With advancements in technology and continued care from farmers,the tradition of harvesting oranges will continue to provide a vital source of nutrition and enjoyment for people worldwide.This composition provides a comprehensive look at the process of picking oranges,from the preparation to the actual harvest and the challenges faced along the way.。

FRUITS AND NUTS PICIKING DEVICEABSTRACTApparatus for harvesting fruits from trees comprising first conduit means, coupling means adjacent a first end thereof and adapted for attachment to a source of vacuum. Throat means including inner and outer sleeve members are provided, the inner sleeve member having a fruit receiving opening at one end thereof, a generally flexible fruit receiving portion arranged inwardly of said fruit receiving opening and having an inwardly converging conical portion. The inwardly converging conical portion is arranged to have a minimum diameter which is not substantially greater than the diameter of the fruit being harvested. A generally rigid cylinder depends from the inwardly converging conical portion and is coupled to the inwardly converging conical portion at one end thereof. Aspirating openings are formed along the rigid cylinder adjacent the inwardly converging conical portion, and a second generally flexible sleeve or conical member is coupled to the rigid cylinder at the end opposite from the fruit receiving opening. This second flexible member is arranged to form a generally flexible closure in response to vacuum being applied through said aspirating openings. The outer sleeve is sealingly secured to the inner sleeve about axially spaced points disposed on opposite sides of said aspirating openings, and means defining a port are arranged on the wall of the outer sleevewith means for coupling said port to said first conduit means.BACKGROUND OF THE INVENTIONThe present invention relates generally to an improved apparatus for harvesting fruits and nuts from trees, wherein vacuum means are coupled to a flexible throat means for removing or detaching the fruit from the tree, and thereafter depositing the fruit in a collecting station. The apparatus of the present invention utilizes a source of vacuum as power for the unit, with the apparatus handling the picked fruit extremely gently.In the harvesting of fruit, including both fruits and nuts, it is frequently desirable to utilize mechanical techniques which will eliminate the need for hand picking of each individual item from the tree. For certain fruits, hand picking is normally required inorder to avoid blemishes from being formed on the fruit. Such hand picking is, of course, costly and extremely slow, and accordinglycontributes to the high cost of such fruit to the consumer.In the past, various techniques have been suggested for the harvesting and extraction of fruits from trees, however these apparatus frequently employ complex electromechanical devices including photocell sensors and the like for locating the fruit, and clamping arms for extracting the fruit from the growing tree. Such apparatus, while enhancing the speed of harvest, normally cannot avoid the risk of damage to the flesh of the fruitIn accordance with the present invention, however, the risk of damage to the flesh is minimized, and a worker may harvest the fruit without necessarily leaving the ground. The apparatus is simple, light in weight, and may be handled from the ground by a suitable extension wand or the like.SUMMARY OF THE INVENTIONTherefore, it is an object of the present invention to provide an improved fruit harvesting apparatus which will enable the picking of fruit or nuts from trees, the apparatus being designed to gently handle the fruit as it is taken from the tree.It is yet a further object of the present invention to provide an improved apparatus for harvesting fruit and nuts from trees, this apparatus being operated and powered by a simple source of vacuum. It is yet a further object of the present invention to provide animproved fruit and nut harvesting device which utilizes a structure without requiring mechanically moving parts.Other and further objects of the present invention will become apparent to those skilled in the art upon a study of the following specification, appended claims, and accompanying drawing.BRIEF DESCRIPTION OF THE DRAWINGFIG. 1 is a side elevational view, partially schematic, illustrating the improved fruit and nut harvesting device of the present invention, and illustrating the apparatus in combination with an elongated fruit transmission conduit means for delivering the harvested material to a collecting station;FIG. 2 is a detail elevational view; partially broken away and partially in section, and illustrating the structure as it is about to extract or harvest fruit from a tree;FIG. 3 is a view similar to FIG. 2, and illustrating the structure as individual items of harvested fruit are being passed through the gathering head; andFIG. 4 is an elevational view illustrating the manner in which the harvesting head can be releasably attached to an extension wand.DESCRIPTION OF THE PREFERRED EMBODIMENT Attention is now directed to FIG. 1 of the drawing wherein the harvesting apparatus generally designated 10 is illustrated, thisapparatus including a harvesting head assembly generally designated 11, the harvesting head being coupled to a first conduit means 12, and a fruit guiding sleeve member 13. A collecting station in the form of a box or the like is shown at 14.With particular attention being directed to the harvesting head means 11, this structure includes a throat assembly comprising a pair of generally coaxially arranged sleeves, including an outer sleeve 15, and an inner sleeve assembly 16. The inner sleeve assembly 16 includes a throat means shown generally at 18, the throat means having a fruit receiving opening as at 19, and an inwardly converging conical portion as at 20. The inwardly converging conical portion 20 has a minimum diameter or constriction area as at 21, this diameter being substantially equal to the diameter of the. fruit being harvested. For normal purposes, this constriction is fabricated from flexible substances so that the diameter of the constriction is adjustably variable when vacuum is applied, this diameter being not substantially greater than the normal diameter of the fruit being harvested.A generally rigid cylinder member 23 is arranged in depending relationship from the inwardly converging conical portion 20, cylinder 23 having a plurality of aspirating openings 24 around the periphery thereof. These openings are adapted to permit a flow of air to pass through, this flow being created by the operation of the vacuum meansshown generally at 26. As can be seen in the harvesting head means, a second generally flexible member, preferably a conical member, is shown at 28, this member being coupled to the rigid cylinder at the end opposite to the inwardly converging conical portion. Member 28 is arranged to close upon itself, if desired, such as is illustrated in FIG. 2. For most purposes, member 28 may be fabricated from a flexible film substance such as flexible polyethylene, stress-oriented polyethylene terephthalate, or the like.With continued attention being directed to FIG. 1, it will be seen that sleeve 15 is sealingly secured to sleeve 16 at axially spaced points disposed on opposite sides of the aspirating openings 24-24. These seal areas are shown as at 30 and 31. Also, means defining a port are arranged on the wall of the sleeve 15 as at 32, these port means being arranged to couple conduit 12 to the harvesting head 11.Attention is now directed to FIG. 2 of the drawing wherein an item of fruit is shown at 35, with the fruit just entering the constriction formed in the inwardly converging conical opening 20, the circumference or surface of the fruit touching the constricted area 21, as illustrated. The vacuum means 26, drawing or aspirating upon the structure, tends to close the opening as at 28, while drawing the fruit 35 inwardly through the system. Upon passing through the opening 21, the fruit will drop through the harvesting head in the fashion shown in FIG.3.It can be appreciated, therefore, that opening 28 is adapted to intermittently open-and-close in response to the vacuum drawing on the structure, and in response to the blockage of the throat means at the constricted area 21. This blocking occurs whenever an article of fruit is present in the throat area.In order to cushion the fall of the individual articles of fruit from the harvesting head into the collecting station, the fruit guiding sleeve 13 is arranged to control the fall of the individual articles and gently deposit them in the collecting box or station such as the box 14. In this fashion, fragile fruits may be collected without risking damage to the skin, flesh, or meat.With attention being directed to FIG. 4, it can be appreciated how the harvesting head 11 may be secured by a closure ring or the like 40 to the wand 41. In this fashion, it is possible for an individual to harvest fruit or nuts from a tree without necessarily having to climb a ladder to ascend to a point where the individual articles of fruit can be harvested by hand.While the present specification has discussed the gathering of fruit, it will be appreciated that the term "fruit" is being utilized in a generic sense, and is intended to include such fruits as apples, citrus fruits such as oranges, lemons and limes, as well as peaches and pears. By suitable selection of throat diameters, nuts can be harvested utilizingthe identical principle. Any conventional materials of construction may be employed for the device, with molded plastic materials being preferred. The inwardly converging conical portion 20 may be fabricated from molded plastic such as nylon, Teflon, vinyl, or the like, while cylinder member 16 may be fabricated from similar materials. Outer sleeve 15, which is preferably rigid, can also be fabricated from any desired material of construction.I claim:1. Apparatus for harvesting fruits from trees comprising:a. first conduit means, coupling means adjacent a first end thereof and arranged forattachment to a source of vacuum;b. harvesting head means with throat means including inner and outer sleeve members, said inner sleeve member having a fruit receiving opening at one end thereof, a generally flexible fruit receiving portion disposed inwardly from said opening and having an inwardly converging conical portion, said inwardly converging conical portion having a minimum diameter which is not substantially greater than the normal diameter of the fruit being harvested, and a generally rigid cylinder depending from said inwardly converging conical portion and being coupled to said inwardly converging conical portion at one end thereof, means defining aspirating openings disposed along said rigidcylinder adjacent said inwardly converging conical portion;c. a second generally flexible conical member coupled to said rigid cylinder at the end opposite to said inwardly converging conical portion and adapted to form a generally flexible closure;d. said outer sleeve being sealingly secured to said inner sleeve at axially spaced points disposed on opposite sides of said openings; ande. means defining a port arranged on the wall of said outer sleeve and having means for coupling said outer sleeve member to said first conduit means.2.

商务英语写作Absolute Advantageabsolute advantage In economics,absolute advantages refers to the ability of a party (an individual, firm, or country) to produce more of a good or service than competitors, using the same amount of resources.A party has an absolute advantage when using the same input as another party, it can produce a greater output.Since absolute advantage is determined by a simple comparison of labor productivities, it is possible for a party to have no absolute advantage in anything.It can be contrasted with the concept of comparative advantage which refers to the ability to produce a particular good at a lower opportunity cost.Adam Smith developed the principle of absolute advantage. The economist Paul Craig Roberts notes that the comparative advantage principles developed by David Ricardo do not hold where the factors of production are internationally mobile. Limitations to the theory may exist if there are single kindof utility. The very fact that people want food and shelter already indicates that multiple utilities are present in human desire. The moment the model expands from one good to multiple goods, the absolute may turn to a comparative advantage. However, global labor arbitrage, where one country exploits the cheap labor of another, would be a case of absolute advantage that is not mutually beneficial.Generally, in international trade, countries export goods and services for which they have an absolute advantage in and import goods and services in which another country has the absolute advantage. According to the theory of absolute advantage, a country that has no absolute advantage in any product or service, then no trade will occur. The two concepts have applications outside international trade, though this is where they are most commonly used. Suppose that two castaways on a desert island gather both fruit and grain, which they then share equally between them. Suppose that Castaway A can gather more fruit per hour than Castaway B, and therefore has an absolute advantage in this good. Nonetheless, it may well make sense for A to leave some fruit-gathering to B. This is because it is possible that B gathers fruit slightly slower than A, but gathers grain extremely slowly. One needs to look atcomparative advantage rather than absolute advantage, to discover how A and B can each best allocate their effort. If A’s initial advantage over B in grain-gathering is greater than his or her advantage in fruit-gathering, then fruit-effort should be transferred from A to B, to the point where A’s comparative advantages in the two goods are equal. Thus it may be rational for fruit to flow from B to A, despite A’s absolute advantage.The concept of absolute advantage is generally attributed to Adam Smith for his 1776 publication An Inquiry into the Nature and Causes of the Wealth of Nations in which he countered mercantilist ideas. Smith argued that it was impossible for all nations to become rich simultaneously by following mercantilism because the export of one nation is another nation’s import and instead stated that all nations would gain simultaneously if they practiced free trade and specialized in accordance with their absolute advantage. Smith also stated that the wealth of nations depends upon the goods and services available to their citizens, rather than their gold reserves. Absolute advantage does not take into account opportunity cost.While there are possible gains from trade with absoluteadvantage, comparative advantage extends the range of possible mutually beneficial exchanges. In other words it is not necessary to have an absolute advantage to gain from trade, only a comparative advantage.Origin of the TheoryThe concept of absolute advantage is generally attributed to Adam Smith for his 1776 publication An Inquiry into the Nature and Causes of the Wealth of Nations in which he countered mercantilist ideas.

In other words it is not necessary to have an absolute advantage to gain from trade, only a comparative advantage.Examples Example 1Party A can produce 5 widgets per hour with 3 employees.example 1Party B can produce 10 widgets per hour with 3 employees.Assuming that the employees of both parties are paid equally, Party B has an absolute advantage over Party A in producing widgets per hour. This is because Party B can produce twice as many widgets as Party A can with the same number of employees.Example 2Country A can produce 1000 parts per hour with 200 workers.example 2Country B can produce 2500 parts per hour with 200 workers.Country C can produce 10000 parts per hour with 200 workers.Considering that labor and material costs are all equivalent, Country C has the absolute advantage over both Country B and Country A because it can produce the most parts per hour at the same cost as other nations. Country B has an absolute advantage over Country A because it can produce more parts per hour with the same number of employees. Country Ahas no absolute advantage because it can’t produce more goods than either Country B or Country C given the same input.Example 3You and your friends decided to help with fundraising for a local charity group by printing t-shirts and making birdhouses.Scenario 1: One of your friends, Gina, can print 5 t-shirts or build 3 birdhouses an hour. Your other friend, Mike, can print 3 t-shirts an hour or build 2 birdhouses an hour. Because your friend Gina is more productive at printing t-shirts and building birdhouses compared to Mike, she has a comparative advantage in both printing t-shirts and building birdhouses.Scenario 2: Suppose Gina wasn’t as agile with the hammer and could only make 1 birdhouse an hour, but she took a sewing class and could print 10 t-shirts an hour. Mike on the other hand takes woodworking and so he can build 5 birdhouses an hour, but he doesn’t know the first thing about making t-shirts so he can only print 2 t-shirts an hour. While Gina would have the absolute advantage in printing shirts, Mike would have an absolute advantage in building birdhouses.。

果园采摘活动高考英语作文Recently, my family and I participated in an orchard picking activity.

The air was fresh and the sun was just beginning to rise. We were given baskets to fill with the fruits we would pick. The orchard was filled with a variety of trees, including apples, oranges, and peaches. The branches were heavy with ripe, juicy fruit, just waiting to be picked.As we began to pick the fruits, I was amazed at the care and attention to detail that the orchard owners put into their work. They explained that each tree needed to be pruned and cared for throughout the year to ensure a healthy harvest. It was a labor of love that required patience and dedication.Picking the fruits was not as easy as it seemed. Each tree had different branches and fruits, some higher up and some lower down. We had to climb ladders, reach, and twist to get to the ripe fruits. My arms were tired from pickingand carrying the fruits, but the satisfaction of selecting the best ones made it worthwhile.After a few hours, our baskets were full. We gathered around and admired the fruits we had picked. They were beautiful, with their bright colors and fresh scent. We couldn't wait to taste them.Back home, we sorted the fruits, washing them carefully. Then, we sat down and enjoyed the fruits we had picked. Each bite was sweeter and more satisfying knowing that we had worked for it.The orchard picking activity was a memorable experience.
