Background technique

The harvester was a utility model by Cyrus McCormick. Harvester It is an integrated machine for harvesting crops. The harvesting and threshing are completed at one time, and the grains are concentrated in the storage bin, and then the grain is transported to the transport vehicle through the conveyor belt. It can also be harvested manually, and the stalks of crops such as rice and wheat are laid in the field, and then used Grain harvesting machinery for picking and threshing. Crop harvesting machinery for harvesting grains and straws of cereal crops such as rice and wheat. Including harvesters, windrowers, balers, grain combine harvesters and grain threshers, etc. Grain harvesting machinery is developed on the basis of various harvesting and threshing tools. The mesh screen threshing filter device is a very important part in the process of using the harvester.

The defects of the existing mesh screen threshing and filtering device: 1. The existing mesh screen threshing and filtering device generally discharges the grains by setting through holes at the bottom, resulting in a small discharge area, so it is necessary to increase the length of the filter barrel In order to increase the rate of grain discharge, if the filter barrel is too long, the energy consumption will be large, and the production cost of the harvester will increase; 2. When the existing mesh threshing and filtering device filters the grain, the straw is directly discharged, However, there will still be some grains on these straws, resulting in insufficient filtration and a large waste rate of grains; 3. The traditional harvester consumes a lot of energy and is easily damaged under heavy load.
