1、中文譯文打包機(jī) 打包機(jī)是一種農(nóng)業(yè)機(jī)械,它用于壓縮已切割和傾斜的作物（如草、稻草或青貯飼料）成易于處理、運(yùn)輸和儲(chǔ)存的小包。常用的打包機(jī)有幾個(gè)不同類型,分別生產(chǎn)不同類型的包-矩形的、圓柱形的,大小各不相同,用麻繩、網(wǎng)或金屬絲纏繞起來(lái)。工業(yè)打包機(jī)還可以用在材料回收設(shè)備上,主要用于包裝需要運(yùn)輸?shù)慕饘?、塑料或紙。圓形打包機(jī)在工業(yè)化國(guó)家最常用的打包機(jī)是這種又大又圓的打包機(jī)。它生產(chǎn)圓柱狀的“圓”或“筒狀”的包。草在打包機(jī)內(nèi)被捲起，使用橡膠帶、固定滾筒,或兩者的組合。當(dāng)包達(dá)到規(guī)定尺寸時(shí),用網(wǎng)或麻繩裹住它,以保持其固有的形狀。打包機(jī)的后面打開(kāi),包被排出。包在這個(gè)階段完成,但也可以用塑料薄膜包裹,當(dāng)在室外儲(chǔ)存時(shí)能
2、保持干草的干燥或者將潮濕的草變成青貯飼料。可變倉(cāng)打包機(jī)通常生產(chǎn)直徑為48至72英寸（120 180厘米）、寬達(dá)60英寸（150厘米）的包。無(wú)論在任何地區(qū)，這些包可以重達(dá)1100至2200磅（500 -1000公斤），包的重量取決于大小，材料，和水分含量。最初，圓形打包機(jī)的構(gòu)思由Ummo Luebbens于大約1910年提出,第一臺(tái)圓形打包機(jī)才生產(chǎn)出來(lái),一直到1947年Allis-Chalmers 引進(jìn)了旋轉(zhuǎn)打包機(jī)之后。由于它的干草包脫水干燥和重量輕的特點(diǎn)從而得以推向市場(chǎng)，到1960年生產(chǎn)結(jié)束時(shí)，AC已經(jīng)銷售了近70000臺(tái)接下來(lái)的一個(gè)重大創(chuàng)新是在1972年，當(dāng)時(shí)Vermeer公司開(kāi)始出售其型號(hào)
3、為605的第一臺(tái)現(xiàn)代圓形打包機(jī)。以前,圓的干草包僅僅是干草縛在一起的腫塊,但Vermeer設(shè)計(jì)使用皮帶將干草緊密結(jié)合起來(lái)形成一個(gè)圓柱體,正如今天所看到的樣子。大型矩形打包機(jī)另一種常用類型的打包機(jī)生產(chǎn)大型的矩形包,每個(gè)包纏繞半打左右的麻繩,然后再打結(jié)。這樣的包非常緊湊，重量又普遍比圓形的包大幾分。在加拿大的草原，它們被稱為草原猛禽。小型矩形打包機(jī)這種打包機(jī)現(xiàn)今是不常見(jiàn)的,但在許多國(guó)家卻是相當(dāng)流行,如新西蘭和澳大利亞,除了大型包的生產(chǎn)，還生產(chǎn)小型矩形 (通常被稱為“正方形的”) 包。每個(gè)包大約是15英寸 x 18英寸 x 40英寸(40 x 45 x 100厘米)。這種包是用二股、三股、或有時(shí)四股
4、麻繩捆綁。這種包非常的輕，一人就能舉起,大小約45至60英寸(1.1到1.5米)。為了形成捆包，料堆中需要打包的原料 (經(jīng)常干草或稻草)被打包機(jī)撿拾器的齒舉起。然后這些原料被拖進(jìn)或鉆進(jìn)一個(gè)長(zhǎng)達(dá)打包機(jī)一個(gè)邊長(zhǎng)的打捆室內(nèi)?；钊偷对诖蚶κ业那岸藖?lái)回地移動(dòng)。刀恰好在活塞的前面，它可以當(dāng)場(chǎng)切斷從撿拾器進(jìn)入打捆室內(nèi)的原料?；钊麑⑦@些原料向后推移，壓縮成捆包。一個(gè)測(cè)量裝置測(cè)量被壓縮的原料的數(shù)量，并在適當(dāng)?shù)拈L(zhǎng)度，觸發(fā)捆綁麻繩并且將其打結(jié)的機(jī)械裝置（打結(jié)器）來(lái)捆綁包裝并將其打結(jié)。當(dāng)下一個(gè)捆包加工成型時(shí)，這個(gè)打結(jié)完的捆包就從打捆室的后面排出到地上或推送到一個(gè)用鉤固定在打包機(jī)后部的特殊的貨車(chē)上。只要有原料需要打包
5、，并且有麻繩來(lái)捆綁包裝，這一過(guò)程就會(huì)一直連續(xù)進(jìn)行。這種形狀的捆包不太適用于大規(guī)模商業(yè)性農(nóng)業(yè)，因?yàn)樘幚碓S多小捆的成本比較高。然而在一些小規(guī)模，低機(jī)械化的農(nóng)業(yè)和養(yǎng)馬業(yè)享有一些名氣。除了使用簡(jiǎn)單的機(jī)械設(shè)備及容易處理外，這些小包也可用來(lái)絕緣和當(dāng)作草捆建筑中的建筑材料。正方形捆包一般也會(huì)比圓捆包要好，因?yàn)樗麄兛梢愿芗囟逊旁谝黄?。便利也是農(nóng)民決定繼續(xù)使用正方形包的一個(gè)主要因素，因?yàn)樗鼈兪沟蔑曫B(yǎng)和在狹窄的地方（馬廄，倉(cāng)庫(kù)等）堆放容易得多。這些舊式打包機(jī)，現(xiàn)如今在農(nóng)場(chǎng)還有許多可以找得到，特別是在干旱地區(qū)，在那里，捆包可以長(zhǎng)期在室外儲(chǔ)存。小型方捆自動(dòng)打包機(jī)成型于1940年。它首先是由New Holland
6、Ag生產(chǎn)制造的，并采用了小型汽油發(fā)動(dòng)機(jī)提供運(yùn)行動(dòng)力。它是基于1937年一個(gè)具有自動(dòng)拾取功能的麻繩打結(jié)打包機(jī)發(fā)明創(chuàng)造出來(lái)的。線材打包機(jī)在1937年以前，捆包是用兩股包裝線材人工包裹的。甚至在更早以前，打包機(jī)是一個(gè)固定的打包設(shè)備，由動(dòng)力輸出裝置（PTO）和傳送帶驅(qū)動(dòng)。干草被加進(jìn)打包機(jī)處并人工用手塞進(jìn)去。自1940年之后，這種打包機(jī)最大的改變是通過(guò)動(dòng)力輸出裝置(PTO)由拖拉機(jī)驅(qū)動(dòng)，而不是通過(guò)內(nèi)置式內(nèi)燃機(jī)。在目前的生產(chǎn)中，人們可以選擇使用麻繩打結(jié)器或者是金屬絲纏繞打結(jié)器的小型方捆打包機(jī)。撿拾和處理方法 在20世紀(jì)40年代，大多數(shù)農(nóng)民將會(huì)使用一輛20馬力甚至更小馬力的小型拖拉機(jī)在田地里捆干草，并且當(dāng)打
7、包機(jī)從田地里走過(guò)時(shí)，捆綁包將會(huì)掉落在地上。另一組工人驅(qū)使馬拉著平板貨車(chē)從旁邊走過(guò)來(lái)。他們用尖銳的金屬鉤來(lái)鉤起捆綁包，并把它們?nèi)拥狡桨遑涇?chē)上，同時(shí)另外一個(gè)助手好這些捆綁包，以便運(yùn)輸?shù)焦葌}(cāng)。后來(lái)，一個(gè)節(jié)約時(shí)間的發(fā)明是直接將平板拖車(chē)接在打包機(jī)之后，這樣草捆包就可以順著舷梯推送給馬車(chē)上的助手。等待在馬車(chē)上的助手用鉤子鉤住草捆包，從舷梯上移開(kāi)，并在馬車(chē)上摞好，同時(shí)等待下一個(gè)生產(chǎn)好的草捆包。最后，隨著拖拉機(jī)馬力的增大，拋擲打包機(jī)就成為了可能。拋擲打包機(jī)消除了需要有人站到馬車(chē)上來(lái)?yè)炱鸩堇Π?。第一個(gè)投擲機(jī)械使用了兩個(gè)快速移動(dòng)的粗糙傳送帶來(lái)抓取草捆包，并把它們以一個(gè)角度向上拋起落到馬車(chē)上。馬車(chē)是由平板車(chē)改造成的
8、前端開(kāi)口的三角架，以此來(lái)充當(dāng)捕捉拋出的草捆包的網(wǎng)。隨著拖拉機(jī)馬力的進(jìn)一步增大，拋擲打包機(jī)的下一代更新產(chǎn)品是液壓投擲打包機(jī)。這種打包機(jī)在包打結(jié)器的后面采用了一個(gè)平板。當(dāng)打好的草捆包從打包機(jī)的后面出來(lái)時(shí)，它們依次被推送到平板上。當(dāng)草捆包完全移動(dòng)到平板上時(shí)，在一個(gè)大型液壓缸的推動(dòng)下，平板就會(huì)突然自動(dòng)彈起，將草捆包拋擲到馬車(chē)上，就像彈射器一樣。這種平板投擲方法與傳動(dòng)帶投擲方法相比，大大減少了施加在草捆包上的壓力。在抓取并投擲草捆包時(shí)，傳送帶投擲運(yùn)輸機(jī)的粗糙的傳送帶給予草捆包的捆帶繩結(jié)很大摩擦力，并且有時(shí)在投擲運(yùn)輸機(jī)上或者是草捆包降落到馬車(chē)上時(shí)，會(huì)導(dǎo)致草捆包的破損。紐荷蘭發(fā)明了一種新的機(jī)器命名為堆垛機(jī)。
9、小型方包從打包機(jī)中出來(lái)后，捆繩朝外，堆垛機(jī)將開(kāi)到草捆包處，將他們撿拾起并放在相當(dāng)于三個(gè)草捆包寬的桌子上（現(xiàn)在草捆包的捆繩朝上）。當(dāng)三個(gè)草捆包放到桌上時(shí)，桌子就會(huì)被舉起，并后退，造成三個(gè)草捆包再次捆繩朝向一側(cè)；這種情況再接著發(fā)生三次，直到有16個(gè)草捆包放在主桌上。之后，主桌就會(huì)像小桌子一樣抬起，使草捆包正對(duì)一個(gè)垂直的桌子。這種機(jī)器可以裝160個(gè)草捆包（10層），通?？拷行牡牟课粫?huì)有交叉層疊，以免再有重量加到草垛頂上時(shí)，草垛會(huì)搖晃，不穩(wěn)定，甚至坍塌。之后滿載的堆垛機(jī)會(huì)被運(yùn)送到谷倉(cāng)，堆垛機(jī)的整個(gè)后部會(huì)傾斜向上，直到垂直。當(dāng)堆垛機(jī)離開(kāi)谷倉(cāng)時(shí)，從機(jī)器延伸出的兩個(gè)推動(dòng)助手會(huì)扶著草垛的底部，把草垛從堆垛機(jī)
10、上移出。在英國(guó)，如果小型方包仍在使用，那么當(dāng)它們從打包機(jī)出來(lái)后，它們通常是被收集到跟在打包機(jī)后的一個(gè)草捆包雪橇上。這種雪橇有4個(gè)通道，由自動(dòng)機(jī)械天平，掛鉤和彈簧控制，每一個(gè)通道劃分容納八個(gè)草捆包。當(dāng)雪橇裝滿后，掛鉤會(huì)自動(dòng)彈起，后面的門(mén)就會(huì)打開(kāi)，把這八個(gè)草捆包整齊的放在地上。之后這些草捆包也許會(huì)人工一個(gè)個(gè)拾起，或者人們用拖拉機(jī)上的草捆包抓取工具，將這八個(gè)草捆包一起拾起。這種草捆包抓取工具是一種特殊的安置在拖拉機(jī)前端的裝貨機(jī)，含有許多液壓驅(qū)動(dòng)的向下彎曲的長(zhǎng)釘。之后，這些草捆包要么堆垛在拖車(chē)上運(yùn)走，要么在田地里堆砌成8層或10層高的立方體草垛。然后這個(gè)立方體草垛由更大的機(jī)器運(yùn)走。這種機(jī)器連接在拖拉機(jī)
11、后，可以?shī)A住草垛側(cè)面，將其整體托起運(yùn)走。處理大型和小型圓形草捆包的一個(gè)簡(jiǎn)單的方法可以在文章Hay Delivery（干草遞送）中看到。相對(duì)于拖拉機(jī)而言，這是一種僅僅自己動(dòng)手的改進(jìn)。兩個(gè)掛鉤被焊接到拖拉機(jī)前端裝載機(jī)的頂端，還有一個(gè)14英尺（4.3米）的日志鏈，它可以使用戶呆在拖拉機(jī)上來(lái)抓取草捆包，運(yùn)輸，堆砌以及再把草捆包放在外面喂養(yǎng)動(dòng)物。形成一條龍作業(yè)。這個(gè)簡(jiǎn)單的操作系統(tǒng)的優(yōu)點(diǎn)是它不必使用昂貴的設(shè)備，也不用在拖拉機(jī)上來(lái)回交換應(yīng)用這些工具。這使得小農(nóng)戶避免了額外器械的花銷，不用僅僅因?yàn)檫@樣一個(gè)功能而另買(mǎi)一臺(tái)拖拉機(jī)。通過(guò)一些小練習(xí)，人們就可以和專業(yè)的液壓捆包抓取機(jī)一樣，快速的拾取草捆包。由糖山農(nóng)場(chǎng)（
12、Sugar Mountain Farm）的沃爾特杰弗里斯（Walter Jeffries）改進(jìn)的這種方法同樣只需要較少的維修養(yǎng)護(hù)，并且比包矛和鉗子更安全。BalerA baler is a piece of farm machinery used to compress a cut and raked crop (such as hay, straw, or silage) into compact bales that are easy to handle, transport and store. Several different types of balers are commonly
13、 used, each producing a different type of bales rectangular or cylindrical, of various sizes, bound with twine, netting, or wire. Industrial balers are also used in material recycling facilities, primarily for baling metal, plastic, or paper for transport.Round balerThe most frequently used type of
14、baler in industrialized countries is the large round baler. It produces cylinder-shaped round or rolled bales. Grass is rolled up inside the baler using rubberized belts, fixed rollers, or a combination of the two. When the bale reaches a predetermined size, either netting or twine is wrapped around
15、 it to hold its shape. The back of the baler swings open, and the bale is discharged. The bales are complete at this stage, but they may also be wrapped in plastic sheeting by a bale wrapper, either to keep hay dry when stored outside or convert damp grass into silage. Variable-chamber balers typica
16、lly produce bales from 48 to 72 inches (120 to 180 cm) in diameter and up to 60 inches (150 cm) in width. The bales can weigh anywhere from 1,100 to 2,200 pounds (500 to 1,000 kg), depending upon size, material, and moisture content. Originally conceived by Ummo Luebbens circa 1910, the first round
17、baler did not see production until 1947, when Allis-Chalmers introduced the Roto-Baler. Marketed for the water-shedding and light weight properties of its hay bales, AC had sold nearly 70,000 units by the end of production in 1960. The next major innovation came in 1972, when the Vermeer Company beg
18、an selling its model 605 - the first modern round baler. Previously, round hay bales had been little more than lumps of grass tied together, but the Vermeer design used belts to compact hay into a cylindrical shape as is seen today.Large rectangular balerAnother type of baler in common use produces
19、large rectangular bales, each bound with a half dozen or so strings of twine which are then knotted. Such bales are highly compacted and generally weigh somewhat more than round bales. In the prairies of Canada they are called prairie raptors.Small rectangular balerA type of baler which is less comm
20、on today in some places but which is still prevalent in many countries such as New Zealand and Australia to the exclusion of large bales produces small rectangular (often called square) bales. Each bale is about 15 in x 18 in x 40 in (40 x 45 x 100 cm). The bales are wrapped with two, three, or some
21、times four strands of knotted twine. The bales are light enough for one person to handle, about 45 to 60 inches (1.1 to 1.5 m).To form the bale, the material to be baled, (which is often hay or straw) in the windrow is lifted by tines in the balers pickup. This material is then dragged or augered in
22、to a chamber that runs the length of one side of the baler. A combination plunger and knife moves back and forth in the front end of this chamber. The knife, positioned just ahead of the plunger, cuts off the material at the spot where it enters the chamber from the pickup. The plunger rams the mate
23、rial rearwards, compressing it into the bales. A measuring device measures the amount of material that is being compressed and, at the appropriate length it triggers the mechanism (the knotter) that wraps the twine around the bale and ties it off. As the next bale is formed the tied one is driven ou
24、t of the rear of the baling chamber onto the ground or onto a special wagon hooked to the rear of the baler. This process continues as long as there is material to be baled, and twine to tie it with.This form of bale is not much used in large-scale commercial agriculture, because of the costs involv
25、ed in handling many small bales. However, it enjoys some popularity in small-scale, low-mechanization agriculture and horse-keeping. Besides using simpler machinery and being easy to handle, these small bales can also be used for insulation and building materials in straw-bale construction. Square b
26、ales will also generally weather better than round bales because a more much dense stack can be put up. Convenience is also a major factor in farmers deciding to continue putting up square bales, as they make feeding and bedding in confined areas (stables, barns, etc.) much easier.Many of these olde
27、r balers are still to be found on farms today, particularly in dry areas, where bales can be left outside for long periods. The automatic-baler for small square bales took on most of its present form in 1940. It was first manufactured by the New Holland Ag and it used a small petrol engine to provid
28、e operating power. It is based on a 1937 invention for a twine-tie baler with automatic pickup.Wire balersBales prior to 1937 were manually wire-tied with two baling wires. Even earlier, the baler was a stationary implement, driven by power take-off (PTO) and belt, with the hay being brought to the
29、baler and fed in by hand. The biggest change to this type of baler since 1940 is being powered by the tractor through its PTO, instead of by a built-in internal combustion engine.In present day production, small square balers can be ordered with twine knotters or wire tie knotters.Pickup and handlin
30、g methodsIn the 1940s most farmers would bale hay in the field with a small tractor with 20 or less horsepower, and the tied bales would be dropped onto the ground as the baler moved through the field. Another team of workers with horses and a flatbed wagon with would come by and use a sharp metal h
31、ook to grab the bale and throw it up onto the wagon while an assistant stacks the bale, for transport to the barn. A later time-saving innovation was to tow the flatbed wagon directly behind the baler, and the bale would be pushed up a ramp to a waiting attendant on the wagon. The attendant hooks th
32、e bale off the ramp and stacks it on the wagon, while waiting for the next bale to be produced.Eventually, as tractor horsepower increased, the thrower-baler became possible, which eliminated the need for someone to stand on the wagon and pick up the finished bales. The first thrower mechanism used
33、two fast-moving friction belts to grab finished bales and throw them at an angle up in the air onto the bale wagon. The bale wagon was modified from a flatbed into a 3-sided skeleton frame open at the front, to act as a catchers net for the thrown bales.As tractor horsepower further increased, the n
34、ext innovation of the thrower-baler was the hydraulic tossing baler. This employs a flat pan behind the bale knotter. As bales advance out the back of the baler, they are pushed onto the pan one at a time. When the bale has moved fully onto the pan, the pan suddenly pops up, pushed by a large hydrau
35、lic cylinder, and tosses the bale up into the wagon like a catapult.The pan-thrower method puts much less stress on the bales compared to the belt-thrower. The friction belts of the belt-thrower stress the twine and knots as they grip the bale, and would occasionally cause bales to break apart in th
36、e thrower or when the bales landed in the wagon.New Holland has invented a machine named the Stackcruiser, or a stacker. Small square bales are dropped by the baler with the strings facing outward, the stacker will drive up to the bales and it will pick it up and set it on a three-bale-wide table (t
37、he strings are now facing upwards). Once three bales are on the table, the table lifts up and back, causing the three bales to face strings to the side again; this happens 3 more times until there are 16 bales on the main table. This table will lift like the smaller one, and the bales will be up aga
38、inst a vertical table. The machine will hold 160 bales (ten tiers), usually there will be cross-tiers near the center to keep the stack from swaying or collapsing if any weight is applied to the top of the stack. The full load will be transported to a barn, the whole rear of the stacker will tilt up
39、wards until it is vertical. There will be two pushers that will extend through the machine and hold the bottom of the stack from being pulled out from the stacker while it is driven out of the barn.In Britain (if small square bales are still to be used), they are usually collected as they fall out o
40、f the baler in a bale sledge dragged behind the baler. This has four channels, controlled by automatic mechanical balances, catches and springs, which sort each bale into its place in a square eight. When the sledge is full, a catch is tripped automatically, and a door at the rear opens to leave the
41、 eight lying neatly together on the ground. These may be picked up individually and loaded by hand, or they may be picked up all eight together by a bale grab on a tractor, a special front loader consisting of many hydraulically-powered downward-pointing curved spikes. The square eight will then be stacked, either on a trailer for transport, or in a roughly cubic field stack eight or ten layers high. This cube may then be transported by a large machine attached to the three-point hitch behind a tractor, which clamps the sides of the cube and lifts it bodily.
