Abstract
The utility model provides a harvester preliminary election sieve, it comprises stepped plate, backup pad, preliminary election sieve etc. That separates the seed grain in advance and remains with miscellaneous. Be fixed with the several backup pad on the stepped plate, a netted or round hole shape preliminary election sieve is fixed to the top of backup pad, and the length of preliminary election sieve surpasss the length of stepped plate, reaches the well anterior segment of cleaning sieve. Harvester preliminary election sieve can filter with miscellaneous surplus the seed grain in advance to increased the ability of cleaning of cleaning sieve, it is unclean effectively to have solved the screening, and the sifter runs the problem of grain, has reduced the loss rate of grain effectively, has improved combine's operating efficiency.
Description
Art：
The utility model is related to a kind of separation seed in advance and miscellaneous remaining pre-selection sieve, is mainly used in united reaper
In.
Background technology：
At present, existing united reaper, seed and it is miscellaneous it is remaining Jing threshing cylinder separate after, between Jing threshing concave plates
Gap is fallen on stepped plate, and stepped plate is enterprising by seed and the miscellaneous remaining sorting screen being sent to below by front-rear reciprocation movement
Row cleans separation.The first half of united reaper is stepped plate, and latter half is sorting screen, therefore cleans sky
Between it is limited, it is little to clean area, cause seed with it is miscellaneous it is remaining separate difficulty, cause united reaper loss late high, make
Industry efficiency is low.
Utility model content：
In order to overcome existing united reaper to clean, area is little causes that loss of cereal crops is high, ineffective asks
Topic, the purpose of this utility model be to provide for it is a kind of can convey and can in advance separate seed sieve with miscellaneous remaining pre-selection
Device.What it can make united reaper cleans area increase 60% or so, so that united reaper cleans energy
Power improves 60%, and the loss of cereal crops of harvester greatly reduces, and increased the work effect of united reaper
Rate.
The utility model solves the technical scheme that its technical problem adopted：Install in the top of original stepped plate
One pre-selection screen device, the length of the pre-selection sieve will be longer than following stepped plate, should reach the middle front part for cleaning sieve
Position.The seed and miscellaneous remaining being fallen first that threshing cylinder threshing is got off sieved on pre-selection sieve, and seed is through pre-
The screening of choosing sieve is fallen on following stepped plate, then Jing stepped plates be transported to below sorting screen on carry out again clearly
Choosing, it is miscellaneous remaining then the middle front part of sorting screen to be delivered directly to by pre-selection screen device.Due to the first half master of sorting screen
If through preselecting the seed for screening out, under the action of the forces of the wind, seed is easy to be sized out, therefore
The ability of cleaning of sorting screen is considerably increased, effectively solves the problems, such as that compass screen surface runs grain.
The beneficial effects of the utility model are：Through the screening in advance of pre-selection sieve, increased sorting screen cleans energy
Power, efficiently solves screening not only, and compass screen surface runs the problem of grain, significantly reduces loss of cereal crops, improves
The operating efficiency of united reaper.
Description of the drawings：
With reference to the accompanying drawings and examples the utility model is described in further detail.
Fig. 1 is the schematic diagram of embodiment of the present utility model.
Fig. 2 is the enlarged drawing of the utility model embodiment partial sectional view.
1, stepped plate in figure, 2, gripper shoe, 3, pre-selection sieve, 4, bolt
Specific embodiment：As shown in figure 1, in the present embodiment, the fixed number of bolt 4 is used on stepped plate 1
Individual gripper shoe 2 (usually 4-6 parts), the top bolt 4 of gripper shoe 2 fixes a netted or circular hole pre-selection
Sieve 3, the length of pre-selection sieve 3 reaches the middle leading portion of sorting screen beyond the length of stepped plate 1.
Claims (1)
1. it is a kind of to separate seed and miscellaneous remaining harvester pre-selection sieve in advance, in being mainly used in united reaper, by stepped plate (1), gripper shoe (2), pre-selection sieve (3) composition, it is characterized in that：With several bolts (4) fixed support plate (2) on stepped plate (1), the top bolt (4) of gripper shoe (2) fixes netted or circular hole pre-selection sieve (3), the length of pre-selection sieve (3) reaches the middle leading portion of sorting screen beyond the length of stepped plate (1).
