In recent years, agricultural machinery departments at all levels have done a lot of work on the comprehensive utilization of straw, and introduced and promoted a batch of corn straw harvesting silage and wheat straw bundling machinery. In order to effectively prevent the destruction and waste of agricultural production resources, straw is strictly prohibited Incineration has made positive contributions in areas such as increasing farmers' income. At the same time lay a good foundation for the comprehensive utilization of crop straw.
Corn harvest silage machinery currently has many domestic manufacturers of such machinery. Among them is the MB-220 disc rotary silage harvester jointly produced by Heilongjiang Zhaoguang Machinery Factory and Germany, which is suitable for silage harvest of feed corn and corn straw. The machine is equipped with a 22 ~ 66 kW tractor, which can only harvest one row at a time, and the price of the equipment is high. The 4YL-1A straw recycling corn combine harvester produced by Henan Zhengzhou Farm Tools Factory is equipped with 18 ~ 22 kilowatt tractors and harvested in a single line. It can complete the ear picking, packing, and straw chopping and packing operations. The price of this machine is low, but the efficiency is not high, it is easy to be blocked, and it is not suitable for large area operations.
Other domestic self-propelled and knapsack corn combine harvesters are mostly smashed and returned to the field when harvesting corn. This operation method wastes straw resources and increases operation costs after returning to the field. In the more economically developed areas, the dairy industry is currently vigorously developed, and corn stalks are taken to return to the field after silage, which is more effective.
In recent years, a corn stalk harvester has been introduced on the market. It can be harvested with ears during operation, or it can be harvested manually after harvesting. The straw is evenly spread on the field after harvesting. Harvest 2 to 3 rows at a time, some also have the function of stubble stubble. Equipped with 8.8 ~ 15 kW tractors, productivity is 0.5 ~ 1.0 hectares / hour.
Wheat straw bundling machine The straw bundling machine can automatically complete a series of operations such as wheat, forage and other crop straws. It can be used with a variety of tractors at home and abroad to adapt to various regional conditions. Round and square bale models. The round baler does not have a knotter to make it relatively simple in structure, small in size, cheaper in price, simple in operation and maintenance, but the disadvantage is low productivity, because it is intermittent operation, stop picking during baling, and the density of the round bales is low. It is not convenient to ship and store. The pick-up range is too small, mostly about 80 cm. If large-scale combine harvesters perform baling operations after harvesting, they are prone to blockages or broken ropes. The square baler has a higher density of bales than round bales, is more convenient to transport and store, can operate continuously, and has high efficiency. However, due to its complicated structure and high manufacturing cost, the price is also high. At present, most of the balers sold in the market are domestic models. The main manufacturers are square and round balers produced by China Agricultural Machinery Modern Hyundai Agricultural Equipment Co., Ltd .; 9YF and 9YY series square bales produced by Shanghai Agricultural and Industrial Xiangming Corporation , Round baler, 9KF, 9KYQ series of square bales and round balers produced by Shanghai Electric Group's modern agricultural equipment, round balers produced by Shandong Guangrao, Bochang and other companies.
Due to its stable performance and reliable quality, the balers imported from abroad occupy a certain market share in China, but their prices are relatively high. At present, they are mainly purchased by state-owned and collective farms.
