[0002] The grain thresher is a mechanical device for separating grains from straw after harvesting, such as wheat, rice, corn, etc. For corn threshing, the use of a thresher improves agricultural production efficiency and reduces the labor intensity of farmers. However, for ordinary farmers in rural areas, such as the Huaibei Plain, many farmers grow corn, and it is not realistic to purchase large mechanical equipment. Due to the complex structure design of the equipment, there is a certain redundancy, the operation threshold is high, and it is not easy for ordinary farmers to master. In addition, the manufacturing cost is high, and the economic burden is heavy, which leads to great difficulties in the popularization and popularization of mechanical equipment, and is not conducive to large-scale application.
