Abstract
In order to overcome not enough that current concave screen exists, the utility model provides a concave screen, the utility model discloses a screen cloth, the unit top cover that threshes, threshing teeth pole, elasticity sieve, this concave screen can increase the elasticity of screen cloth, improves the work efficiency that concave screen threshed.
Description
Technical field
This utility model relates to a kind of united reaper FIELD OF THE INVENTIONThe device, a kind of bullet that can increase screen cloth
Property, improve the concave grate of the work efficiency of concave grate threshing.
Background technology
The concave grate of harvester has the effect separated with corn by the straw of crops, the typically centre at screen cloth and is provided with
Rotating threshing toothed bar, drives rice rotating from the inlet to the outlet, thus by threshing toothed bar by corn and straw
The magazins' layout such as stalk, weeds, existing concave grate includes that screen cloth and thresing machine top cover, screen cloth and thresing machine top cover link together
Rear formation cylindrical shape, but the area of screen cloth and thresing machine top cover is basically identical, and crops are being sieved under the drive of threshing toothed bar
Motion in the cylindrical shape concave grate that net and thresing machine top cover are formed, but thresing machine top cover does not has the effect of threshing so that paddy
Thing on the upside of concave grate cannot threshing, the efficiency causing concave grate threshing is low.
At present, known concave grate structure is to include screen cloth, thresing machine top cover, threshing toothed bar.This concave grate can not be as early as possible
Crops are carried out threshing, inefficient.
Summary of the invention
For the deficiency overcoming existing concave grate to exist, this utility model provides a kind of concave grate, and this concave grate is permissible
Increase the elasticity of screen cloth, improve the work efficiency of concave grate threshing.
This utility model solves the technical scheme is that this utility model of its technical problem and includes screen cloth, thresing machine
Top cover, threshing toothed bar, elastic sieve.The interior surface of described screen cloth is provided with an elastic sieve.
Screen cloth and thresing machine top cover connect the cylinder that formation is hollow.
Threshing toothed bar is arranged in concave grate.
Concave grate is coaxially disposed.
The beneficial effects of the utility model are, can increase the elasticity of screen cloth, improve the work efficiency of concave grate threshing.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the part structural map of concave grate embodiment.
In figure
1, screen cloth
2, thresing machine top cover
3, threshing toothed bar
4, elastic sieve.
Detailed description of the invention
In the embodiment shown in fig. 1, this utility model includes screen cloth 1, thresing machine top cover 2, threshing toothed bar 3, elastic sieve 4.
Described screen cloth 1 and thresing machine top cover 2 connect the cylinder that formation is hollow, and threshing toothed bar 3 is arranged in concave grate, and
And be coaxially disposed with described concave grate, the interior surface of described screen cloth 1 is provided with an elastic sieve 4.When being embodied as, threshing toothed bar
Crops are launched on elasticity sieve 4 by high-speed rotation, because elastic sieve elasticity is relatively big, can further for crops threshing be processed,
Last crops carry out threshing through screen cloth 1 again so that it is departing from more complete, this utility model is by increasing the radian of screen cloth 1
Greatly, improve the elasticity of screen cloth 1, thus increase the area of screen cloth 1, reach to improve concave grate can the effect of threshing area, thus
On the premise of not increasing other structures, improve the efficiency of threshing.
As known by the technical knowledge, this utility model can be by other essence without departing from its spirit or the reality of essential feature
The scheme of executing realizes.
Embodiment disclosed above, for each side, is all merely illustrative, and is not only.All at this
All it is included in the utility model in the range of utility model or being equal to the change in the range of this utility model.
