Abstract
The utility model relates to a separating and re-threshing device for threshers, which is used for separating threshing crops in threshers and threshing crops again which are not thoroughly threshed. The purpose is to provide a separating and re-threshing device for threshers, which can effectively separate crops in threshing and separating and thresh crops again which are not thoroughly threshed. The separating and re-threshing device for threshers comprises a threshing part, a blower, an elevator, a primary screen and a secondary screen; the two screens are used for separating crops; the left crops which are not thoroughly threshed are returned to the threshing part to thresh again; thus, the utility model improves recovery rate.
Description
The utility model relates to a kind of thresher, particularly relevant in this thresher the threshing crop cleaned and to not taking off the rethreshing device that good crop carries out threshing once more.
Existing thresher is used for crops such as paddy and wheat are carried out threshing mostly.These threshers have mostly used a screen cloth that is positioned at threshing part below to clean, and emersion object after the threshing is screened with screen cloth, cereal is regained and foreign material are removed.Owing to only be difficult for crop is deviate from fully, therefore, only use once threshing and the thresher cleaned will cause bigger waste in the effect results from the tangerine bar by a threshing.
The purpose of this utility model provides is a kind ofly carrying out threshing to crop, can clean effectively when cleaning, and the thresher that the crop that will not purify carries out threshing is once more cleaned and rethreshing device.
This is cleaned and rethreshing device comprises, the threshing part, be positioned at the blower fan of threshing part one side, be arranged on a screen cloth of threshing part and blower fan below, a described screen cloth forms towards blower fan one side from the threshing part, an aspiration channel of blower fan is facing to the wire side in a screen cloth downstream, it is characterized in that: be provided with the crop of will sift out in the downstream of a described screen cloth and rise to the elevator that is higher than the threshing part, described elevator outlet bottom be provided with towards below the slide plate of threshing part lopsidedness, be provided with in the bottom of this slide plate towards answering of threshing part and take off the secondary screen cloth that the porch tilts, the inlet scoop of blower fan secondary aspiration channel is being set between slide plate bottom and screen cloth.
Like this, when work, at first threshing in sheller unit of crop, emersion object drops to the enterprising row filter of screen cloth one time, when the motion along with screen cloth moves to the inlet of an aspiration channel of blower fan, impurity such as tangerine bar are absorbed from the inlet scoop, the remaining end that moves to screen cloth is risen by elevator, drop on the slide plate from the outlet of elevator, slide to the secondary screen cloth, by way of the inlet scoop of blower fan secondary aspiration channel, the foreign material that wherein contain are absorbed once more the process that drops to the secondary screen cloth from slide plate, thereby have improved the rate of cleaning.Screen once more after remaining crop falls into the secondary screen cloth, the crop after the screening is reclaimed, the good crop that do not take off that sifts then takes off inlet from answering of screen cloth end and enters into the threshing part and carry out threshing twice, thereby has avoided the waste of crop.
Fig. 1 is that the utility model is cleaned and the schematic diagram of an embodiment of rethreshing device.
Among the figure: the 1st, slide plate, the 2nd, aspiration channel of blower fan, the 3rd, blower fan secondary aspiration channel, the 4th, secondary screen cloth, 5 is screen clothes, the 6th, and elevator, the 7th, blower fan, the 8th, threshing part, the 9th, take off inlet again, 10 is upper sieve sheets of a screen cloth, 11 is lower screen sheets of a screen cloth.
An embodiment of the present utility model is described with reference to the accompanying drawings.
There is shown one and be used for thresher that soybean is carried out threshing and cleans, this thresher is being provided with threshing part 8, blower fan 7 and elevator 6 from right to left respectively.Blower fan 7 is provided with threshing part 8 its axles.Below above-mentioned three parts from threshing part 8 to the elevator 6 downward-sloping screen clothes 5 that are being provided with a time, this screen cloth 5 is provided with mesh upper sieve sheet 10 and mesh that the soybean of results will be a little greatly and wants littler lower screen sheet 11 than soybean, one side of blower fan 7 is being provided with an aspiration channel 2 that extends from the middle part of blower fan 7 downwards, this aspiration channel is opened on the end of upper sieve sheet 10, towards lower screen sheet 11.The end of a screen cloth 5 leads to the inlet of elevator 6, elevator 6 is its outlet of upright shape and is positioned at the top, bottom in elevator 6 outlets is being provided with the slide plate 1 opposite with the incline direction of a screen cloth 5, this slide plate 1 downward-sloping top that extends to threshing part 8, its terminal opening with the secondary aspiration channel 3 that extends towards the top from blower fan 7 opposite sides is adjacent, the side of ending in the threshing part 8 of the peristome lower edge of secondary aspiration channel 3 is being provided with and the identical secondary screen cloth 4 of above-mentioned slide plate 1 incline direction, the mesh of this gentle breeze 4 is slightly larger than soybean, have the outlet of leading to tanker at the rear portion of this secondary screen cloth 4, with threshing, soybean after cleaning is reclaimed.Be provided with answering that the crop that is used to allow secondary screen cloth 4 sift out enters in the top outer of threshing part and take off inlet 9, and the rear portion on the eye of wind of secondary screen cloth is provided with the opening that takes off inlet 9 again facing to above-mentioned.
During work, the crop of deviating from from threshing part 8 drops on the upper sieve sheet 10 of a screen cloth 5, along with shaking of a screen cloth 5, soybean of taking off and the impurity little than soybean drop on the lower screen sheet 11 from upper sieve sheet 10, bigger tangerine bar and the beans folder that do not taken off etc. and on upper sieve sheet 11 to lower slider, in the time of near aspiration channel 2 peristomes that arrive blower fan 7, the residue that stays on the upper sieve sheet 10 drops on the lower screen sheet 11 from upper sieve sheet 10, meanwhile the knot bar that 7 of blower fans will be wherein lighter etc. is absorbed by an aspiration channel 2, also part is trapped in absorbing on the lower screen sheet 11 simultaneously, heavily reaches less than the impurity of soybean and then remove down from the mesh decline of lower screen sheet 11 than light impurity.Remaining material arrives the inlet of elevator 6 at last, and is raised from its outlet discharge, falls to secondary screen cloth 4 along slide plate 1.
The way that drops to secondary screen cloth 4 from slide plate 1, crossed over the peristome of the secondary aspiration channel 3 of blower fan 7, thereby remaining impurity has been absorbed along secondary aspiration channel 3.Only there are soybean and the heavier inferior beans folder that do not take off to drop on the secondary screen cloth 4, the fortune of shaking along with secondary screen cloth 4, the bottom that soybean drops to secondary screen cloth 4 is recovered to the tanker (not shown) from outlet, and the thing that do not purify that is trapped in above the secondary screen cloth 4 then falls into threshing part 8 and carries out threshing once more from answering of the top, right side of threshing part 8 being taken off inlet 9 opening opposing.
In addition, the inlet scoop that once reaches secondary aspiration channel 2,3 of described blower fan 7 can be made adjustable, so just, the clean level that can clean according to crop and loss amount position and the distance of adjusting each inlet scoop, thus realized not only cleaning clean but also guaranteed the purpose of the high rate of recovery.
