Abstract
The utility model discloses a cleaning and selecting device for an improved combine, comprising a first allocation screw conveyer and a second allocation screw conveyer which are mounted below the sheller of the combine, a shaking board which shakily transfers the grain mixture thrown by the first allocation screw conveyer and the second allocation screw conveyer to a cleaning and selecting screen, a draught fan blowing to the grain mixture, and a thrown roller arranged between the shaking board and the cleaning and selecting screen to scatter the grain mixture. By utilizing the rotation of the thrown roller, the grain mixture is scattered and delaminated effectively, and the grain mixture is screened and selected by the draught fan and the cleaning and selecting screen, thus greatly improving the cleaning and selecting performance of the cleaning and selecting device.
Description
Technical field
The utility model relates to a kind of combine, relates in particular to a kind of cleaning plant of combine.
Background technology
The operation principle of combine cleaning plant is now: crop moves to making axial flow in the combine sheller unit, in this process, seed is come off, the cauline leaf distortion, seed and partial impurities and short cauline leaf have been taken off under centrifugal action, falling first distributes screw feeder and second to distribute the screw feeder place, distributing screw feeder and second to distribute screw feeder to throw by first delivers on the shuttle board of cleaning plant, and paddy hybridization compound is delivered on the sorting screen surface by the porpoise of shuttle board, by the porpoise of sorting screen and the effect of blower fan, partial impurities and short cauline leaf are removed, and clean crop kernel is sent into tanker.The shortcoming of the cleaning plant of prior art is that shuttle board is when transmitting paddy hybridization compound to sorting screen, a large amount of paddy hybridization compounds are not to fall on the compass screen surface continuously, but a pile a pile drop on the compass screen surface, the wind-force of blower fan can not be well separated paddy is assorted, also have a strong impact on the work of cleaning of sorting screen, caused cleaning loss easily.
Summary of the invention
Technical problem to be solved in the utility model provides the combine cleaning plant that a kind of improved impurity elimination is effective and cleaning efficiency is high.
The purpose of this utility model is to realize like this, improved combine cleaning plant comprises that being installed in first of combine sheller unit below distributes screw feeder and second to distribute screw feeder, the first paddy hybridization compound that distributes screw feeder and second to distribute screw feeder to throw to send is delivered to shuttle board on the sorting screen by shake, blower fan to the blowing of paddy hybridization compound is provided with the roller of tossing that paddy hybridization compound is broken up between described shuttle board and the sorting screen.
The utility model is owing to adopt said structure, improved combine cleaning plant comprises that being installed in first of combine sheller unit below distributes screw feeder and second to distribute screw feeder, the first paddy hybridization compound that distributes screw feeder and second to distribute screw feeder to throw to send is delivered to shuttle board on the sorting screen by shake, blower fan to the blowing of paddy hybridization compound is provided with the roller of tossing that paddy hybridization compound is broken up between described shuttle board and the sorting screen; Paddy hybridization compound is broken up in the toss rotation of roller of utilization, makes its effective layering, utilizes fan and sorting screen that paddy hybridization compound is screened again, can improve the ability of cleaning of cleaning plant greatly.
Description of drawings
Accompanying drawing is the structure principle chart of the utility model embodiment.
Embodiment
As shown in drawings, improved combine cleaning plant comprises that being installed in first of combine sheller unit 1 below distributes screw feeder 2 and second to distribute screw feeder 3, the first paddy hybridization compound that distributes screw feeder 2 and second to distribute screw feeder 3 to throw to send is delivered to shuttle board 4 on the sorting screen 5 by shake, blower fan 6 to the blowing of paddy hybridization compound, be provided with the roller 7 of tossing that paddy hybridization compound is broken up between described shuttle board 4 and the sorting screen 5, the described roller 7 of tossing is provided with the transfer roller of a plurality of plectrums for the surface, the roller 7 of tossing is one, also can be set to two or three.
During work, crop is under 1 effect of combine sheller unit, seed is come off, the cauline leaf distortion, long cauline leaf is outside sheller unit 1 terminal directly discharge grain header, seed and partial impurities have been taken off and short cauline leaf passes notch board 8 under centrifugal action, dropping on first distributes screw feeder 2 and second to distribute screw feeder 3 places, distributing screw feeder 2 and second to distribute screw feeder 3 throwing backward to send first drops on the shuttle board 4 under the effect, porpoise by shuttle board 4 is delivered to roller 7 places of tossing with paddy hybridization compound, the grain mixture is broken up in the toss rotation of roller 7 of utilization, make its effective layering, the grain mixture is thrown delivered on the sorting screen 5 simultaneously, effectively clean by sorting screen 5 and 6 pairs of paddy hybridizations of blower fan compound, clean seed enters seed screw feeder 10 by seed slide plate 9, and then enters silo; Do not purify fully that short fringe is first-class assorted surplusly to enter tailing auger 12 by assorted surplus slide plate 11, carry out secondary and clean through entering cleaning room after taking off again again, remaining impurity is then discharged outside the grain header.
The above only is that of the present utility model for example protection domain of the present utility model is as the criterion with the content of claim, any based on modification of the present utility model all within protection domain of the present utility model.
Claims (2)
1. improved combine cleaning plant, comprise that being installed in first of combine sheller unit (1) below distributes screw feeder (2) and second to distribute screw feeder (3), distribute screw feeder (2) and second to distribute paddy hybridization compound that screw feeder (3) throwing send to be delivered to shuttle board (4) on the sorting screen (5) with first by shake, blower fan (6) to the blowing of paddy hybridization compound is characterized in that: be provided with the roller of tossing (7) that paddy hybridization compound is broken up between described shuttle board (4) and the sorting screen (5).
