Technical field

The utility model relates to the technical field of threshing machines, in particular to an agricultural threshing machine.

Background technique

Threshing is one of the most important steps in the crop harvesting process. It removes the harvested grains from the ears and separates other extracted materials such as short stems, debris and grains as much as possible. It is necessary to use a thresher for operation. The thresher is a harvesting machine that can separate crop grains from the stalks. It mainly refers to the harvesting machinery of grain crops. There are certain disadvantages in the use of the existing thresher. After threshing, the grains still contain a large amount of debris, short stems and other debris. The threshing efficiency is low and it needs to be sorted and cleaned again. The operation is cumbersome. The debris is carried out by the wind, and the wind carrying debris and dust is discharged to the environment. It affects people's working environment and easily causes certain pollution to the natural environment. For this reason, we propose an agricultural threshing machine.
