Corn thresher

Abstract

The invention discloses a corn thresher, which comprises a feed hopper, a threshing device and a bracket, wherein the feed hopper is arranged on the upper part of the threshing device; the threshing device is fixed on the bracket; a discharge outlet is arranged at the lower end of the threshing device; the threshing device consists of a threshing drum, a pressing plate and a baffle plate; the pressing plate is positioned above the threshing drum and is arc-shaped; the baffle plate is positioned on the side face of the threshing drum and the pressing plate; an arc-shaped threshing bin is enclosed by the threshing drum, the pressing plate and the baffle plate; the inlet end of the threshing bin is bigger than the outlet end of the threshing bin in caliber; threshing tendons or threshing teeth are arranged on the threshing bin; a protecting shell is arranged at the bottom of the threshing drum; the pressing plate consists of a pressing plate, a pressing tube, a pressing strip and a pressure spring; and an elastic device is arranged on the top of the pressing plate. The corn thresher solves the problems of feeding and threshing corn cobs with different sizes, can feed and thresh in batches, is good in threshing effect and high in threshing speed, has a threshing rate of nearly 100 percent, and is simple in structure and low in both production cost and use cost.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a corn thresher. Background technique [0002] Most of the traditional agricultural corn threshers adopt the method of threshing one by one. The feed port of the corn thresher can only feed the corn cobs horizontally and threshing one by one, and cannot realize multiple corn cobs feeding and threshing at the same time, so the speed of threshing is low, and because the size of the running channel of the threshing cylinder is relatively fixed, For corn cobs with different diameters, the cleaning rate is low, and the broken rate may be too large, or the corn cobs may be broken. In order to solve the problem that corn cobs with different cob diameters can be threshed, there was another patent No. 200720064680.9 invention titled a technical solution for a widely applicable small corn thresher. Different corn cobs can be threshed, but batch feeding and discharging cannot be real...

Problems solved by technology

[0002] Most of the traditional agricultural corn threshers adopt the method of threshing one by one. The feed port of the corn thresher can only feed the corn cobs horizontally and threshing one by one, and cannot realize multiple corn cobs feeding and threshing at the same time, so the speed of threshing is low, and because the size of the running channel of the threshing cylinder is relatively fixed, For corn cobs with different diameters, the cleaning rate is low, and there will be an excessive breakage rate, or the corn cobs will be broken

In order to solve the problem that corn cobs with different cob diameters can be threshed, there was another patent No. 200720064680.9 invention titled a technical solution for a widely applicable small corn thresher. Different corn cobs can be threshed, but batch feeding and discharging cannot be realized. Of course, the threshing speed is not fast, and the threshing rate is not ideal.
