The corn thresher has the function of threshing the dried corn ears. Most of the threshing plates are axial-flow drum type threshing plates and vertical threshing plate type threshing plates. The threshing machine has the characteristics of high production efficiency, good threshing quality, simple and convenient operation, simple structure, firmness, durability, reliable work, convenient use and maintenance and the like, so the threshing machine is always popular with farmers for many years.
The corn thresher mainly comprises a roller, a concave plate, a sieve, a fan, a feeding hopper, a seed sliding plate, a spiral guide rod and the like. It adopts an axial flow threshing device which is tangentially fed with a spike stalk and discharges the spike stalk at the axle end. The process flow comprises the following steps: the corn ears enter the roller through the feeding hopper and are threshed under the impact of the high-speed rotary roller and the interaction of the corn ears, the roller and the concave plate. Most of the seeds and fine impurities are cleaned by the fan through the concave holes. The light impurities are blown out from the impurity discharge port, and the seeds slide out of the machine by the seed slide plate. The cob moves backwards along the axial direction of the roller, is discharged out of the machine through the surface of the vibrating sieve from an outlet at the shaft end, and partial grains carried in the cob leak down through the sieve holes and enter the grain sliding plate to slide out of the machine.
In the prior art, the position of a sieve is fixed, when the corn grains pass through the sieve, although some light impurities can be blown out from an impurity discharge port, some heavy impurities can enter a grain sliding plate and slide out of the machine along with the corn grains after being filtered, and therefore impurities are excessive when the corn grains are collected.
