Description
Technical field
The present invention relates to a kind of agricultural miniature thresing machines, in particular to a kind of to be based on reversely rotating double roller and can be improved de-
The maize sheller of net rate.
Background technique
It is well known that maize sheller is a kind of widely applied small agricultural machinery, be one kind can by niblet and
Obstruct isolated equipment.
Existing maize sheller mainly includes the components such as feed hopper, front and back storehouse shell, left side plate, and the rear storehouse shell takes off
Grain end is equipped with manual centering type position adjusting mechanism, and in the position under the action of regulating mechanism, rear storehouse shell threshing end can be around its hinge
It connects end to swing up and down, to realize the threshing of different size corn ear, when specific works, mostly uses the grain threshing roller with threshing muscle high
Speed rotation squeezes impact with storehouse shell, the side plate of threshing space surrounding and carries out threshing, and threshing means are relatively simple, and corn ear
Threshing space move forward during cannot good stress, to influence threshing performance and threshing efficiency；On the other hand,
Maize sheller in the prior art does not consider how to prevent lesser when the corn ear to different size carries out threshing
Corn ear is leaked out from thresing machine, cannot achieve the purpose that abundant threshing.
Simultaneously as rear storehouse shell is integral, corn ear can be by rear Cang Keding during threshing spatial altitude moves
It rises, causes rear storehouse shell tail portion opening to become larger, Corn stick is caused to leak out in the case where not abundant threshing from rear storehouse shell tail end.
Based on the above reasons, it now needs that the structure of maize sheller is further improved.
Summary of the invention
To overcome problem above of the existing technology, the present invention provides one kind based on reverse rotation double roller and can mention
The maize sheller of high threshing ratio is arranged elastomeric element by the suitable position in maize sheller, promotes different rule to reach
The corn ear of lattice is sufficiently collided with elastomeric element, improves the effect of threshing performance.
The present invention is realized by the following technical scheme:
It is a kind of based on reversely rotating double roller and can be improved the maize sheller of threshing performance, including feed hopper, preceding storehouse shell, after
Storehouse shell, left plate, right side plate, bottom plate and discharge port are formed between preceding storehouse shell, rear storehouse shell, left plate, right side plate and bottom plate
There are two the thrashing rollers reversely rotated for interval installation in threshing space, and the rear storehouse shell is laterally by two pieces of arc-shaped pressing plate groups
At being fixed at intervals with several elastic portions at rear storehouse shell outer ledge when thrashing roller is to when rotating on the outside of maize sheller
Part A；When thrashing roller is rotated to maize sheller inside, several elastic portions are fixed at intervals at rear storehouse shell inside edge
Part A；The length direction and thrashing roller of the elastomeric element A is in an angle；And every piece of arc-shaped pressing plate two sides of tail line side
To being provided with elastomeric element B.
Further, the elastomeric element B is less than or equal to the elastic portion in the endpoint location close to the side elastomeric element A
Another endpoint location of part B.
Further, the preceding storehouse shell two sides are articulated with rack, and preceding storehouse shell back edge and rear storehouse shell front are along fixation；Or institute
It states preceding storehouse shell two sides and is fixed in rack, preceding storehouse shell back edge is with rear storehouse shell front along hinged.
Further, the rear storehouse shell is integral or rear storehouse shell front and back successively includes independent rear storehouse shell A and rear storehouse shell
B。
It further, further include threshing chamber height adjusting device, and rear storehouse shell is connected with threshing chamber height adjusting device.
Further, the threshing chamber height adjusting device includes: transfer the files tooth, regulation handle, control stick, eccentric wheel, pressure
Block and several guide spiro rods；The eccentric wheel being arranged on control stick is contacted with briquetting；The guide spiro rod is set to rear storehouse shell tail
The tail portion of portion or rear storehouse shell A and rear storehouse shell B are cased with spring on guide spiro rod；The briquetting passes through its through-hole and spring on one side
It is in contact, another side is fastened by nut.
Further, in the lateral cambered surface of every piece of arc-shaped pressing plate of rear storehouse shell tail portion or rear storehouse shell B interval be provided with it is several
The line direction of strip aperture, strip aperture two sides is provided with elastomeric element B.
Further, rear storehouse shell tail portion or rear storehouse shell B entirety or tail portion are by the spaced and parallel row of several lateral arcuation ribs
Column, and with the hollow pressing plate of arcuation that several lengthways of rod are welded as a whole；It is horizontal between the adjacent arcuation rib of every piece of arc-shaped pressing plate
To being provided with elastomeric element B.
Further, annulus is cased on the elastomeric element B, the annulus is flexibly connected with rear storehouse shell.
Further, further include the locating rod for being set to rack two sides, spring is cased in locating rod, the briquetting one side is logical
It crosses its through-hole and spring interface touches.
Further, the briquetting on rear storehouse shell A and rear storehouse shell B is affixed by connection sheet, the front setting of the rear storehouse shell B
There is guide spiro rod, is cased with spring on guide spiro rod；The one side of the connection sheet is touched by its through-hole and spring interface, and another side is logical
Cross nut fastening.
Compared with prior art, beneficial effects of the present invention are as follows:
1, the present invention is on prior art basis, by fixing several elastomeric elements at rear storehouse shell-side edge interval,
So that on the basis that corn ear during the high-speed motion of threshing space, is collided by itself collision and storehouse shell, side plate,
Sufficiently thorough extrusion and collision occurs under the action of elastomeric element, to improve corn ear threshing performance.
2, on the one hand the present invention stops Corn stick in inabundant threshing by elastomeric element is arranged at rear storehouse shell tail end
In the case where from rear storehouse shell tail end leak out；On the other hand the abundant collision for utilizing the elastomeric element and corn ear, improves corn ear
Threshing performance.
3, the present invention in use can be by rear storehouse shell during the high velocity impact in threshing space because of corn ear
It jacks up so that rear storehouse shell tail portion opening becomes larger, Corn stick is caused to leak in the case where not abundant threshing from rear storehouse shell tail end
Out, it then ensure that the spatial variations of rear storehouse shell A do not interfere with rear storehouse shell B using independent rear storehouse shell A and rear storehouse shell B, prevent
Corn stick leaks out in the case where not abundant threshing from corn threshing machine tail end.
4, the present invention increases the quantity of maize sheller moment charging using the maize sheller for reversely rotating double roller,
Threshing efficiency is improved, while by means of the reverse rotation of double roller cylinder arrangement elastomeric element in place and by means of front and back
The rear storehouse shell of segmented designs, and comprehensive further enhances the working efficiency of corn ear threshing performance and maize sheller.
5, it is that corn ear during high speed exercise will be elastic in order to prevent that fixing piece, which is arranged, in the present invention on elastomeric element B
Part B jacks up, and further limits elastomeric element B in longitudinal displacement.
