联合收割机是一种集收割、输送、脱粒、分离和清选功能于一体的农作物联合收获作业机械,主要用于小麦、水稻、玉米及大豆等农作物的田间收获作业,是农机产品中科技含量高、制造工艺要求特殊、结构最为复杂的农机产品。由于其具有作业效率高、机动性强等特点,大大缩短了收获时间,有利于抢农时,能大幅度减轻农民的劳动强度,因此在广大农村得到越来越广泛的应用。而联合收割机产品质量问题也越来越引起社会各界的关注。
Combine harvester is a combined crop harvesting operation machine that integrates harvesting, conveying, threshing, separating and cleaning. It is mainly used for field harvesting of crops such as wheat, rice, corn and soybeans. It is a scientific and technological content of agricultural products High, the manufacturing process requires special, the most complex structure of agricultural machinery products. Due to its high operation efficiency and strong maneuverability, it greatly shortens the harvesting time and helps to reduce the labor intensity of peasants when it is beneficial to rob the peasants. Therefore, it has been widely applied in the vast rural areas. However, the quality of combine harvesters has also drawn more and more attention from all walks of life.
