corn thresher

Abstract

The invention discloses a corn thresher, comprising a feed hopper, a threshing device and a support, the feed hopper is installed on the upper part of the threshing device, the threshing device is fixed on the support, the lower end of the threshing device is provided with a discharge port, the threshing device consists of a threshing cylinder, a pressing plate Composed of baffles, the pressing plate is located above the threshing cylinder in an arc shape, the baffle is located on the side of the threshing cylinder and the pressing plate, and an arc-shaped threshing chamber is formed between the threshing cylinder, pressing plate and the baffle, and the diameter of the inlet port of the threshing chamber is larger than the diameter of the outlet port; The threshing cylinder is provided with threshing tendons or threshing teeth, and the bottom of the threshing cylinder is provided with a protective shell; the pressure plate is composed of a pressure plate, a pressure tube, a pressure strip and a pressure spring, and an elastic device is arranged on the top of the pressure plate; The problem of feeding and threshing corn cobs with different diameters, and can be fed and threshed in batches, the threshing effect is very good, the threshing speed is very fast, the cleaning rate can almost reach 100%, the structure is simple, the production cost and the use cost are relatively low Low.

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.
