Abstract

Provided is a full-automatic multi-functional thresher, which is an improvement of cereal crop thresher. An machine frame (28) is arranged on the bottom of the complete machine, a transmission mechanism of the machine head is fixedly arranged on a supporting plate (27) at the right end of the machine frame (28), a clearing mechanism is fixedly arranged on the lower part of the lower roller (3), and a transmission machine (8) inside a holding feeding mechanism is arranged between the upper roller (5) and the lower roller (3). A cog (16), a lower gear (15) and a medium gear (13) inside a medium wheel box (11) are fixed mesh connection. Vertically and horizontally interwinding separation strips (14) are fixedly arranged on a concave board sift (24), a first wind machine (22) is fixedly arranged on the wind inlet port of an upper layer sift (19), and a second wind machine is fixedly arranged on the wind inlet port of the lower layer sift (21). The transmission machine (8) and the machine frame (28) are of hinged connection, the machine uses double wind channel double layer sift to clear and select, and effectively solves the problem of lower clean threshing ratio and relatively high impurity content percentage in threshing. The gap between the lower roller and the lower roller can be adjusted to thresh a plurality of corns, and the transmission machine can be lifted or dropped down to suit the half feeding and also the full feeding procession mode.

Description

The full-automatic multi-functional thresher

Technical field: the utility model belongs to cereal crops thresher.

Background technology: traditional thresher can only a kind of crops of threshing paddy rice, and only are fit to partly feed processing mode, and that existing multi-functional thrasher exists threshing performance is low and percentage of impurity is higher and device structure is complicated, the problem of maintenance difficulty.

Summary of the invention: the utility model is a kind of full-automatic multi-functional thresher of development; make it can the threshing paddy rice again can other cereal crops of threshing; not only adaptation partly feeds processing mode, can adapt to full feeding processing mode again, and solves the low and higher problem of percentage of impurity of threshing performance emphatically.The utility model is made up of frame 28, head transmission mechanism, dressing mechanism, clamping intake mechanism.Frame 28 is bases of complete machine, and frame 28 is fixed on the bottom of complete machine; The head transmission mechanism is fixed on the support plate 27 of frame 28 right-hand members, and dressing mechanism is fixed on the below of bottom roll 3, and the conveyer 8 in the clamping intake mechanism is arranged on the centre of cylinder 5 and bottom roll 3.The head transmission mechanism is made up of power wheel 20, belt wheel 6, belt wheel 2, belt wheel 4, belt wheel 1, last cylinder 5, bottom roll 3, intermediate wheel box 11.In the intermediate wheel box 11 cog 16, lower gear 15 is that fixed engagement is connected with idle wheel 13.Dressing mechanism is made up of upper sieve 19, lower screen 21, slubbing blower fan 22, two road blower fans 23, concave grate 24, eccentric wheel 10, shake roller 25.Fixing the parting bead 14 that interweaves in length and breadth on the concave grate 24, the place, inlet scoop of upper sieve 19 is fixed with slubbing blower fan 22, and the place, inlet scoop of lower screen 21 is fixed with two road blower fans 23.The clamping intake mechanism is made up of feeding platform 12, conveyer 8, reductor 7, belt wheel 26.Conveyer 8 is to be articulated and connected with frame 28, and reductor 7 is fixed on the support plate 27 of frame 28 central axis right-hand members.Its operation principle is: with whole the bundled feeding platform 12 of constantly putting into of cereal, conveyer 8 is sent into it between up-down roller, but adjust the just various cereal that do not wait of threshing particle of distance between the upper and lower cylinder, after being included in the concave grate 24 below the bottom roll 3, fall on the upper sieve 19, through the slubbing blower fan with straw with after grain separates, fall again on the lower screen 21, to leak a small amount of straw that selects through two road blower fans again separates once more with cereal, eccentric wheel 10 drives shake roller 25 does upper and lower riddler, realizes full-automatic full feed type threshing function; When partly feeding, conveyer 8 started carry out half feeding processing mode threshing.The utility model has adopted two air channels blower fan and staged double deck screen structure, solved the low and higher problem of percentage of impurity of threshing performance in the threshing effectively, particularly the improvement of concave grate makes that straw was more prone to separating of grain in full feeding threshing course, the up-down roller adjustable gaps is whole, can adapt to the threshing of different cereal, conveyer is that articulated form is connected with frame, and conveyer rotates to start around jointed shaft and carries out half feeding processing mode threshing.What blower fan adopted in the former type thresher is single suction air port blower fan, and what the utility model adopted is two air channels blower fans, and reality has increased screening sequence one, makes grain and straw separating effect better.
