Corn thresher

Abstract

The invention discloses a corn thresher, which comprises a bracket, a feed hopper, a threshing device, a discharge opening and a power device, wherein the feed hopper is connected with the threshing device; the discharge opening is positioned at the bottom end of the threshing device; the threshing device comprises threshing bins sectionally positioned above a shelling cylinder and a receiving bottom board, and the whole threshing bin is larger on the upper part and smaller on the lower part; the first section of the threshing bin is connected with the feed hopper; and the opening diameter at the upper end of the first section of the threshing bin is larger than that of the lower end, and other threshing bins are respectively provided with a bin shell positioned outside and an automatic threshing bin height adjusting structure positioned between the bin shell and the threshing cylinder. The corn thresher realizes shelling for a plurality of times, solves the problem of feeding and threshing of maize cobs with different cob diameters, has good shelling effect, can feed and discharge in batch, and can automatically steer to feeding to make the maize cobs enter the threshing bins for threshing; and the threshing speed is two times quicker than that of the prior corn thresher, and thethreshing performance nearly reaches 100 percent.

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 feeding and threshing one by one. For example, the corn thresher with the patent No. The design of the channel, the feed port can only allow the corn cobs to be fed and threshed one by one horizontally, but not multiple corn cobs can be fed and threshed at the same time, and the size of the threshing operation channel is relatively fixed. For corn with different diameters corn cobs, the threshing effect will be very unsatisfactory, the threshing speed is not fast, and there are also cases where the breakage rate is too large and the corn cobs will be broken. There is also a widely applicable small corn thresher with a patent number of 200720064680.9. Although it solves the problem that corn cobs with different diameters can be threshed, it still cannot real...

[0002] Most of the traditional agricultural corn threshers adopt the method of feeding and threshing one by one. For example, the corn thresher with the patent No. The design of the channel, the feed port can only allow the corn cobs to be fed and threshed one by one horizontally, but not multiple corn cobs can be fed and threshed at the same time, and the size of the threshing operation channel is relatively fixed. For corn with different diameters corn cobs, the threshing effect will be very unsatisfactory, the threshing speed is not fast, and there are also cases where the crushing rate is too large, and the corn cobs will be broken.

There is also a widely applicable small-sized corn thresher with a patent number of 200720064680.9. Although it solves the problem that corn cobs with different diameters can be threshed, it still cannot realize batch feeding and discharging. The threshing speed is of course Not fast, and the threshing effect is not ideal
