Description

A kind of maize sheller based on reverse rotation double roller

Technical field

The utility model is related to a kind of agricultural miniature thresing machine, more particularly to a kind of to be taken off based on the corn for reversely rotating double roller Grain machine.

Background technology

It is well known that maize sheller is a kind of wide variety of small agricultural machinery, be one kind can by iblet and Obstruct separate equipment.

The main part such as including feed hopper, front and rear storehouse shell, left side plate of existing maize sheller, the rear storehouse shell it is de- Grain end is provided with manual centering type position adjusting mechanism, and in the presence of the position adjusting mechanism, rear storehouse shell threshing end can be around its hinge End is connect to swing up and down, it is more high using the grain threshing roller with threshing muscle during specific works so as to realize the threshing of different size corn ear Speed rotation, storehouse shell, side plate the extruding impact with threshing space surrounding carries out threshing, and threshing means are relatively simple, and corn ear During threshing space moves forward can not stress well, so as to have influence on threshing performance and threshing efficiency；On the other hand, Maize sheller of the prior art does not consider, when the corn ear to different size carries out threshing, how to prevent less Corn ear spills from thresing machine, it is impossible to reach the purpose of abundant threshing.

Simultaneously as rear storehouse shell is one overall, corn ear can be by rear Cang Keding during threshing spatial altitude is moved Rise, cause rear storehouse shell afterbody opening to become big, cause Corn rod to be spilt from rear storehouse shell tail end in the case of without abundant threshing.

Based on above reason, now need to be further improved the structure of maize sheller.
