31 helically arrange in the inner surface of outer roller 3, so can reverse kneading action to material formation, it is possible to increase threshing is imitated
Really.It is preferred that, the two ends of annular threshing cavity 100 are respectively feed end and discharge end, and some first threshing tooths 21 are helically arranged
Helix extend to discharge end from feed end along the rotation direction of inner roller 2, what some second threshing tooths 31 were helically arranged
Helix extends to discharge end from feed end along the rotation direction of outer roller 3, and the first threshing tooth 21 and the second threshing tooth 31 are adopted
With this kind of arrangement form, the torsion kneading action to material can be further improved, and make material from feed end gradually to discharging
End motion carries out threshing, it is ensured that the continuity of threshing work, it is to avoid block.
In the present embodiment, the pivot center of inner roller 2 is parallel with the pivot center of outer roller 3 and is arranged at intervals, namely interior
The pivot center of roller 2 deviates the pivot center of outer roller 3, so makes annular threshing cavity 100 between inner roller 2 and outer roller 3
Width it is inconsistent, be easy to material from annular threshing cavity 100 it is wider from feed, can be more preferable at the narrower place of annular threshing cavity 100
Formation extruding, so as to further improve threshing performance, it is ensured that Threshing.It is preferred that, the pivot center and outer roller of inner roller 2
3 pivot center is located in same perpendicular, and the pivot center of inner roller 2 is located at below the pivot center of outer roller 3, this
Annular threshing cavity 100 is the form that bottom is small, top is big between sample inner roller 2 and outer roller 3, makes material from annular threshing cavity
The feeding of 100 tops more facilitates, easily, while material annular threshing cavity 100 bottom forms and reverses extruding, can make Threshing
Reach optimal.
In the present embodiment, second rotates two turns of drive component including two or more drag ring 4 and in frame 1
Axle 5, each drag ring 4 is fixed in outer roller 3 and central axis is overlapped with the pivot center of outer roller 3, two rotating shafts 5 it is parallel and
The each drag ring 4 of correspondence is equipped with a friction driving roller 6 in arranged for interval, each rotating shaft 5, and each drag ring 4 is supported on two rotating shafts 5
On upper corresponding friction driving roller 6, at least one rotating shaft 5 is connected with rotary drive mechanism.Outer roller 3 passes through drag ring 4
Support is arranged on the friction driving roller 6 of two rotating shafts 5, outer roller 3 is rotated around fixed axis, rotating shaft 5 is with friction-driven
When taking turns 6, by the rubbing action of friction driving roller 6 and drag ring 4, outer roller 3 can be driven to rotate.Two rotating shafts of the present embodiment
5 connect a rotary drive mechanism respectively.
In the present embodiment, first, which rotates drive component, includes the first rotary drive and first band wheel drive mechanism, first
The drive end of rotary drive is connected by first band wheel drive mechanism with the rotary shaft of inner roller 2, so as to drive 2 turns of inner roller
It is dynamic；Rotary drive mechanism includes the second rotary drive and the second belt wheel transmission mechanism, and the second rotary drive passes through the second band
Wheel drive mechanism is connected with rotating shaft 5, so that drive shaft 5 is rotated.First band wheel drive mechanism and the second belt wheel transmission mechanism are equal

It is dynamic, and the rotation direction of inner roller 2 is opposite with the rotation direction of outer roller 3；
（B）Using feeding mechanism by material from one end of inner roller 2 send into the cavity between inner roller 2 and outer roller 3 in carry out
Threshing.
Because the rotation direction of inner roller 2 is opposite with the rotation direction of outer roller 3, it is possible to decrease inner roller 2 and outer roller 3
Single velocity of rotation, namely inner roller 2 and the velocity of rotation of outer roller 3 all can be relatively low, and then the impact strength to material can be reduced
And hitting power, while the threshing separating effect of material and loss late is ensured, the breakage of material seed is minimized, is beneficial to
The storage and breeding of material seed；Threshing can be also improved simultaneously, reduce the possibility of feed blocking.It is preferred that, inner roller 2
Velocity of rotation with outer roller 3 is inconsistent, namely both are differential motion, preferably improve threshing speed, can so enter one
Step improves Threshing, and the possibility of feed blocking can be prevented effectively from again, is played a part of " automatically cleaning ".
The detailed process and principle of the thresing machine threshing be：Feeding mechanism（Inclined transporter）Material is sent into from feed end
After annular threshing cavity 100 between inner roller 2 and outer roller 3, in the presence of the first threshing tooth 21 and the second threshing tooth 31, thing
Material is in a screwing motion manner to discharging end motion, and the first threshing tooth 21 and the second threshing tooth 31 are in dozen to material shape in this process
The effect of hitting, while inner roller 2 and outer roller 3 are rotated backward, there is kneading action to the existing percussion of material, forms torsional mode again
Threshing, makes the Threshing of material reach most preferably；The velocity of rotation of inner roller 2 and outer roller 3 can set smaller simultaneously, right
The impact strength reduction of material, so as to reduce the breakage rate of material seed.
The thresing machine of the present embodiment and methods of threshing are applied to rape, the threshing of Soybean and Other Crops.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example.To those of ordinary skill in the art, the improvement and change resulting in the case where not departing from the technology of the present invention concept thereof
Change and also should be regarded as protection scope of the present invention.
