Description
Technical field
The present invention relates to a kind of agricultural miniature thresing machine, particularly to a kind of based on rotating Vortex double roller and the maize sheller of threshing performance can be improved.
Background technology
It is known that maize sheller is a kind of wide variety of small agricultural machinery, it is that one kind by iblet and can obstruct detached equipment.
Existing maize sheller mainly includes feed hopper, storehouse shell in front and back, the parts such as left side plate, the threshing end of described rear storehouse shell is provided with manual centering type position adjusting mechanism, in the presence of this position adjusting mechanism, storehouse shell threshing end can swing up and down around its hinged end afterwards, thus realizing the threshing of different size corn ear, during specific works, how using the grain threshing roller high-speed rotation with threshing muscle, storehouse shell with threshing space surrounding, side plate extruding impact carries out threshing, threshing means are more single, and corn ear can not stress well during the forward movement of threshing space, thus having 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 from spilling from thresing machine it is impossible to reach the purpose of abundant threshing.
Simultaneously as rear storehouse shell is overall for one, rear storehouse shell jack-up can be led to the shell afterbody opening change of rear storehouse greatly during the motion of threshing spatial altitude by corn ear, lead to Corn rod to spill from rear storehouse shell tail end in the case of not having abundant threshing.
Based on above reason, now need the structure of maize sheller is further improved.
Content of the invention
For the problem above overcoming prior art to exist; the invention provides a kind of based on rotating Vortex double roller and the maize sheller of threshing performance can be improved; elastomeric element is arranged by the suitable position in maize sheller; fully collided with reaching the corn ear promoting different size and elastomeric element, improve the effect of threshing performance.
The present invention is realized by technical scheme below：
A kind of based on rotating Vortex double roller and the maize sheller of threshing performance can be improved, including feed hopper, front storehouse shell, left threshing bin shell, right threshing bin shell, left plate, right plate, base plate and discharging opening, in front storehouse shell, left threshing bin shell, right threshing bin shell, left plate, in the threshing space being formed between right plate and base plate, interval is provided with homodromal left thrashing roller and right thrashing roller, and it is disposed with threshing baffle plate between described left thrashing roller and right thrashing roller, in left threshing bin shell, at the horizontal same direction lateral edges of right threshing bin shell, interval is fixed with some elastomeric element A, the length direction of described elastomeric element A respectively with left thrashing roller, right thrashing roller is in an angle；Described left threshing bin shell, right threshing bin shell are arc-shaped pressing plate, and left threshing bin shell two sides of tail line direction is provided with elastomeric element B with right threshing bin shell two sides of tail line direction.
Further, described elastomeric element B is in corresponding left thrashing roller, the endpoint location near elastomeric element A side for the right thrashing roller another endpoint location less than or equal to this elastomeric element B.
Further, when thrashing roller rotate counterclockwise, elastomeric element A is respectively positioned on left threshing bin shell, on the left of right threshing bin shell, and left thrashing roller installation site is higher than right thrashing roller；When thrashing roller turns clockwise, elastomeric element A is respectively positioned on left threshing bin shell, on the right side of right threshing bin shell, and right thrashing roller installation site is higher than left thrashing roller.
Further, described front storehouse shell both sides are articulated with frame, and front storehouse shell back edge is fixedly connected with left threshing bin shell, right threshing bin shell front edge；Described front storehouse shell both sides are fixed in frame, and front storehouse shell back edge and left threshing bin shell, right threshing bin shell front are along hinged.
Further, described left threshing bin shell, right threshing bin shell be respectively that one is overall or described left threshing bin shell, right threshing bin shell before and after respectively include independent storehouse shell A and storehouse shell B successively.
Further, also include threshing chamber height adjusting device, described left threshing bin shell, right threshing bin shell are all connected with threshing chamber height adjusting device.
Further, described threshing chamber height adjusting device includes：Transfer the files tooth, regulation handle, control stick, eccentric wheel, briquetting, some guide spiro rods；The eccentric wheel being arranged on control stick is contacted with briquetting；Described guide spiro rod is arranged at left threshing bin shell, right threshing bin shell afterbody or storehouse shell A and storehouse shell B afterbody, and guide spiro rod is cased with spring；Described briquetting one side is passed through its through hole and is touched with spring interface, and another side is fastened by nut.
Further, every piece of arc-shaped pressing plate two sides of tail line direction of described storehouse shell B is provided with elastomeric element B.
Further, in the horizontal cambered surface of left threshing bin shell, right threshing bin shell afterbody or storehouse shell B, interval has some strip perforates, and the line direction of described strip perforate both sides is provided with elastomeric element B.
Further, left threshing bin shell, right threshing bin shell afterbody or storehouse shell B entirety or storehouse shell B afterbody are by the spaced and parallel arrangement of some horizontal arcuation ribs, and the arcuation hollow pressing plate being welded as a whole with some lengthways of rod；It is horizontally arranged with elastomeric element B between adjacent arcuation rib.
Further, described elastomeric element B is cased with annulus, described annulus is flexibly connected with left threshing bin shell or right threshing bin shell.
Further, also include being arranged at the locating rod of frame both sides, locating rod is cased with spring, described briquetting one side is passed through its through hole and touched with spring interface.
