The straw baling machine can automatically pick up, bale, bundle and bundle a batch of wheat straw, pasture and other crop straws. It can be used with many types of tractors at home and abroad to adapt to various geographical conditions. It has round bales and squares. Bundle 2 models. The round baler has relatively simple structure and small size due to no knotter, its price is cheaper and the operation and maintenance is simple, but the disadvantage is that the productivity is low because it is an intermittent operation, and the pickup is stopped and the bundled round bale has a low density. Shipment and storage are not very convenient. The pick-up rate is too small, about 80 centimeters. If a large combine harvester performs baling after harvest, it is prone to clogging or breaking ropes. The square bale machine has a higher density of straw bales than the round bale, which is convenient for transportation and storage, and can be continuously operated with high efficiency. However, because of its complicated structure and high manufacturing cost, the price is also high. At present, most of the balers sold on the market are domestic models. The main manufacturers include square bales and round balers produced by the Modern Agricultural Equipment Corporation of the Chinese Academy of Agricultural Machinery; the 9yf and 9yy series of square bales produced by the Shanghai Nongye Industry and Commerce Xiangming General Corporation. , round bale machine, 9kf, 9kyq series square bales, round balers manufactured by Shanghai Electric Group modern farm equipment, round balers manufactured by Shandong Guangrao, Bochang, etc.
