Problems solved by technology

[0002] At present, the structure of the drum in the corn thresher includes a roller body and a sieve body. The bottom of the roller body is the sieve body. The structure of the corn cob is cylindrical, the corn cob is between the roller body and the sieve body, and the threshing tooth squeezes the corn kernels on the corn cob when the roller body rotates, but this structure often cannot completely thresh the corn cob, and will still A small number of kernels remain on the cob, and the cob often gets stuck as it moves forward, resulting in inefficient threshing

Embodiment Construction

[0014] like Figure 1 to Figure 3 As shown, an embodiment of the present invention includes a roller body 1 and a sieve body 2, the roller body 1 is horizontally arranged in the sieve body 2, the roller body 1 rotates in the sieve body 2 through a power transmission device, and the sieve body 2 is fixedly arranged in the threshing On the machine, the installation of the roller body 1 and the sieve body 2 and the setting of the discharge port on the sieve body 2 are all well-known technologies of those skilled in the art, and will not be repeated here; in this embodiment, the roller body 1 is set There are threshing teeth 3, and the threshing teeth 3 are distributed in a single helix from the first to the last one. The threshing teeth 3 include cylindrical teeth 31 and blade teeth 32. The blade teeth 32 are rectangular plates, and the blade teeth 32 are along the spiral line. The direction is inclined, that is, its bottom is fixed on the roller body 1 along the helix, but it is...

Abstract

A threshing cylinder of a corn thresher comprises a roller and a screen. The roller is provided with threshing teeth which are distributed from the first to the last in a single helical line manner. The threshing teeth include cylinder teeth and blade teeth, wherein the blade teeth are obliquely arranged along the helical line. The screen is a transversely disposed cylinder, and the upper portion of the screen is a solid plate and the lower portion of the screen is a screening plate. A plurality of first projections are arranged on the inner side of the solid plate. The first projections are arranged on the inner side of the solid plate on the upper portion of the cylindrical screen, threshing efficiency of corn cobs is greatly improved, and threshing of the corn cobs is more thorough. The threshing teeth include blade teeth, and pushing the corn cobs forward is improved, so that the problem that the corn cobs are stuck between the roller and the screen is solved, and threshing capacity is more improved due to the fact that second projections are arranged on the side of the blade teeth.

Description

technical field [0001] The invention relates to a corn thresher, in particular to a corn thresher drum. Background technique [0002] At present, the structure of the drum in the corn thresher includes a roller body and a sieve body. The bottom of the roller body is a sieve body. There are threshing teeth on the roller body. The structures of the threshing teeth are all cylindrical. In between, when the roller body rotates, the threshing teeth squeeze the corn kernels on the corn cobs, but this structure often cannot completely thresh the corn cobs, and there will still be a small amount of corn kernels on the corn cobs. It often gets stuck during forward movement, resulting in low threshing efficiency. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings in the prior art, the object of the present invention is to provide a threshing drum for a corn thresher machine that completely threshes corn cobs without the phenomenon of corn cob...
