Abstract
The utility model discloses a cleaning and sorting device for combines, which comprises a front cylinder sieve arranged at the lower part of a grain outlet of a threshing device of the combine, a rear cylinder sieve which is parallel to the front cylinder sieve, arranged at one side of the front cylindrical sieve, an impurity outlet arranged at the rear part of the rear cylinder sieve, a front blowing blower and a rear wind-suction blower which are used for removing impurity in crop grains; a vibration sieve is arranged between the rear cylinder sieve and the impurity outlet; on one hand, the utility model has the advantage of high work efficiency of the cylinder sieve; on the other hand, the utility model has the advantage of good effect of removing impurity of the vibration sieve; the utility model is an improvement on the existing cleaning and sorting 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 the cleaning plant of combine is now: crop moves to making axial flow in the combine sheller unit, in this process, seed is come off, the cauline leaf distortion, taken off seed and partial impurities and lacked cauline leaf and fallen into cleaning plant at centrifugal action, by the effect of sieve in the cleaning plant and blower fan, partial impurities and short cauline leaf are removed, and the seed of crop is sent into tanker.The sieve of prior art has two kinds, and a kind of is drum sieve, and this arrangement works efficient height is not easy to get rid of but its shortcoming is a part minor axis leaf.Another kind is a vibratory sieve, and it has good impurity elimination effect, but its efficient is low, easy break-down, the results effect that does not reach.
Summary of the invention
The purpose of this utility model is to provide a kind of cleaning plant with the high combine of good impurity elimination effect and cleaning efficiency.
The purpose of this utility model is to realize like this, the cleaning plant of combine comprises the preceding drum sieve that is installed in combine sheller unit grain export below, drum sieve one side and in the parallel back drum sieve of preceding drum sieve before being installed on, be arranged at the impurity outlet at drum sieve rear portion, back, but be used for removing the rear fan of the preceding blower fan of drying of making composition granule impurity and air draught, be provided with a vibratory sieve between described back drum sieve and the impurity outlet.
As a kind of improvement, described vibratory sieve is that eccentric shaft drives.
The utility model is owing to adopt said structure, the cleaning plant of combine comprises the preceding drum sieve that is installed in combine sheller unit grain export below, drum sieve one side and in the parallel back drum sieve of preceding drum sieve before being installed on, be arranged at the impurity outlet at drum sieve rear portion, back, but be used for removing the rear fan of the preceding blower fan of drying of making composition granule impurity and air draught, be provided with a vibratory sieve between described back drum sieve and the impurity outlet, it has the advantage of drum sieve high efficiency on the one hand, it has the advantage of the good impurity elimination effect of vibratory sieve on the other hand, it has improved existing cleaning plant greatly, has the excellent popularization using value.
Description of drawings
Accompanying drawing is the cutaway view of the utility model embodiment.
Embodiment
As shown in drawings, the cleaning plant of combine comprises the preceding drum sieve 2 that is installed in combine sheller unit grain export below, drum sieve 2 one sides and in the parallel back drum sieve 3 of preceding drum sieve 2 before being installed on, be arranged at the impurity outlet 6 at drum sieve 3 rear portions, back, but be used for removing the preceding blower fan of drying 4 of making composition granule impurity and the rear fan 5 of air draught, be provided with a vibratory sieve 7 between described back drum sieve 3 and the impurity outlet 6.Described vibratory sieve 7 drives for eccentric shaft.
During work, crop moves to making axial flow in combine sheller unit 1, in this process, seed is come off, the cauline leaf distortion, long cauline leaf is dished out by impurity outlet 13, taken off seed and partial impurities and short cauline leaf guide functions under centrifugal action through front slide 11 and tail skid 12, fall into the preceding drum sieve 2 of the rotation of cleaning plant, preceding drum sieve 2 is by rotating behind the forward direction, seed to be cleaned is thrown to back drum sieve 3, back, back drum sieve 3 continues seed just to be cleaned to be thrown, and the impurity and the short cauline leaf of band small part seed are thrown to vibratory sieve 7, and vibratory sieve 7 is dished out impurity and short cauline leaf from impurity outlet 6, seed reclaims from vibratory sieve 7 belows, in entire work process, preceding blower fan 4 is drum sieve 2 and the blowing of drum sieve 3 bottoms, back forward constantly, and constantly drum sieve 2 and back drum sieve 3 top air draughts in the past of rear fan 5, seed is the past drum sieve 2 constantly, back drum sieve 3 and vibratory sieve 7 fall, and with seed and the separated from impurities of crop and send into tanker.
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. the cleaning plant of combine, comprise the preceding drum sieve (2) that is installed in combine sheller unit grain export below, be installed on preceding drum sieve (2) one sides and in the parallel back drum sieve (3) of preceding drum sieve (2), be arranged at the impurity outlet (6) at drum sieve (3) rear portion, back, be used for removing the preceding blower fan (4) of drying of making composition granule impurity but and the rear fan of air draught (5), it is characterized in that: be provided with a vibratory sieve (7) between described back drum sieve (3) and the impurity outlet (6).
2. the cleaning plant of combine as claimed in claim 1 is characterized in that: described vibratory sieve (7) is that eccentric shaft drives.
