Abstract
The utility model discloses an improved cleaning device of a combined harvester, which comprises a first and a second dispensing screw feeders which are arranged below a threshing device of a combined harvester, wherein grain and minor cereal mixtures which are thrown by the first and the second screw feeders are transferred to a shaking board on a cleaning sieve through shake and a blower which is used for blowing wind to the grain and minor cereal mixtures. A circular cylinder sieve which is used for primarily sieving and thrashing the grain and cereal mixtures is arranged between the shaking board and the cleaning sieve. Because of the arrangement of the circular cylinder sieve, on one hand, the primary sieving operation of the grain and minor cereal mixtures is realized, and the working load of the cleaning sieve is lightened; on the other hand, the rotation of the circular cylinder sieve is used for thrashing residual grain and minor cereal mixtures so that the effective stratification of the grain and minor cereal mixtures is realized. The blower and the cleaning sieve are used for sieving the grain and minor cereal mixtures, and the cleaning ability of the cleaning device can be improved.
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 a kind of combine cleaning plant that impurity elimination is effective and cleaning efficiency is high of improvement.
The purpose of this utility model is to realize like this, the combine cleaning plant of improvement 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, to the blower fan of paddy hybridization compound blowing, be provided with the drum sieve that paddy hybridization compound is carried out Preliminary screening and breaks up between described shuttle board and the sorting screen.
The utility model is owing to adopt said structure, the combine cleaning plant of improvement 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, to the blower fan of paddy hybridization compound blowing, be provided with the drum sieve that paddy hybridization compound is carried out Preliminary screening and breaks up between described shuttle board and the sorting screen; Because the setting of drum sieve, on the one hand paddy hybridization compound is carried out the live load that Preliminary screening has alleviated sorting screen, the rotation of drum sieve is broken up remaining paddy hybridization compound again on the other hand, make its effective layering, utilize blower 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, the combine cleaning plant of improvement 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, to the blower fan 6 of paddy hybridization compound blowing, be provided with the drum sieve 7 that paddy hybridization compound is carried out Preliminary screening and breaks up between described shuttle board 4 and the sorting screen 5; Described drum sieve 7 is two.
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 drum sieve 7 places with paddy hybridization compound, drum sieve carries out Preliminary screening to paddy hybridization compound, alleviated the live load of sorting screen, utilize the rotation of drum sieve 7 to break up remaining grain mixture simultaneously, 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. Gai Liang 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 drum sieve (7) that paddy hybridization compound is carried out Preliminary screening and breaks up between described shuttle board (4) and the sorting screen (5).
2. the combine cleaning plant of improvement as claimed in claim 1, it is characterized in that: described drum sieve (7) is two.
