打包机是一种农业机械,它用于压缩已切割和倾斜的作物(如草、稻草或青贮饲料)成易于处理、运输和储存的小包。常用的打包机有几个不同类型,分别生产不同类型的包-矩形的、圆柱形的,大小各不相同,用麻绳、网或金属丝缠绕起来。工业打包机还可以用在材料回收设备上,主要用于包装需要运输的金属、塑料或纸。
圆形打包机
在工业化国家最常用的打包机是这种又大又圆的打包机。它生产圆柱状的“圆”或“筒状”的包。草在打包机内被捲起,使用橡胶带、固定滚筒,或两者的组合。当包达到规定尺寸时,用网或麻绳裹住它,以保持其固有的形状。打包机的后面打开,包被排出。包在这个阶段完成,但也可以用塑料薄膜包裹,当在室外储存时能保持干草的干燥或者将潮湿的草变成青贮饲料。可变仓打包机通常生产直径为48至72英寸(120~ 180厘米)、宽达60英寸(150厘米)的包。无论在任何地区,这些包可以重达1100至2200磅(500 -1000公斤),包的重量取决于大小,材料,和水分含量。
Baler
A 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 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 baler
The most frequently used type of 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 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 typically 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
