Abstract

A kind of thresher; cylinder shaft is fixed on the thresher shell, and threshing cylinder is fixed on the cylinder shaft, and outer anti-grass circle is fixed on the thresher shell; in the anti-outside grass circle of threshing cylinder cover, the threshing cylinder tooth of the most close outer anti-grass circle is fixed on the threshing cylinder and outwards anti-grass circle tilts.This thresher straw does not twine cylinder shaft, both can use separately, can be installed on the grain header again and use.

Description

A kind of thresher

Affiliated technical field

The utility model relates to a kind of thresher.

Background technology

At present, all there is a shortcoming in known thresher: straw twines cylinder shaft, increases load, even crashes.

Summary of the invention

In order to overcome the deficiency that existing thresher straw twines cylinder shaft, increases load even crash, the utility model provides a kind of thresher, and this thresher straw does not twine cylinder shaft.

The technical scheme that its technical problem that solves the utility model adopts is: the cylinder shaft activity is fixed on the thresher shell, and threshing cylinder is fixed on the cylinder shaft, and outer anti-grass circle is fixed on the thresher shell, in the anti-outside grass circle of threshing cylinder cover.Because outer anti-careless snare is on threshing cylinder, straw on the anti-grass circle, outside the thresher that flies out again, can not be wrapped on the cylinder shaft outside threshing cylinder slides into, and both can use separately, can be installed on the grain header yet and use.

The beneficial effects of the utility model are that straw does not twine cylinder shaft, both can use separately, can be installed on the grain header yet and use.

Description of drawings:

The utility model is described in further detail below in conjunction with drawings and Examples.
