Description

Soybean thresher

The utility model belongs to the technical field that thresher machine is gone up in the agricultural field.

At present, in the three provinces in the northeast of China, main producing region of soybean, the threshing of most peasant soybean is still continued to use roller and is had a meeting, an audience, etc. well under one's control, the mode of manually winnowing and separating; Also have part peasant household to use to substitute machinery and carry out the soybean threshing, as 5TS-50 wheat thresher, this traditional type is for cutting the streaming rice-wheat thresher, by frame, cut flow roller, notch board, straw shaker, sorting screen, clean fan and collect the grain device and form.Because the limitation of this machine threshing principle and design dominant ideas, although the soybean threshing percentage of damage of this machinery is low, the cleaning rate variance still need winnow after taking off, and power consumption is big, and the user does not welcome.The combine that uses for large-scale farm also can carry out soybean harvesting and threshing, as the IH1460 of Wan Guo company, the East Germany E512 of the U.S., the homemade Great Northern Wilderness etc., though percentage of damage reduces the clean rate height, but loss is big before cutting, price is high, and general peasant buys and can not use.

To be that design is a kind of adapt to a kind of new thresher that current scale of agricultural production and most of peasant household use to the purpose of this utility model, should have threshing performance height, safe and reliable and reduce characteristics such as pollution.

The utility model is made up of frame, cylinder, loam cake, notch board, feeding platform, Lysimachia sikokiana mechanism, suction shell fan, sorting screen and transmission mechanism, and cylinder is installed on the frame by bearings, and loam cake is being covered in the top of cylinder, and the following half cycle of cylinder is contained by notch board.Thresher belongs to shaft flow structure, and the one end is an arrival end, is provided with the feeding platform, be provided with Lysimachia sikokiana mechanism and inhale the shell fan at the port of export of the other end, sorting screen be arranged on notch board below.

Above-mentioned diameter of cylinder is 500-600mm, and length is 125-135mm, and cylinder adopts open (being that non-envelope is covered formula) structure, and the tingia on the plate tooth of arranging vertically is to be formed by direct punching out on the board foot bar, and tingia line is in the shape of a spiral arranged.

Inboard at loam cake is fixed with guide plate, and the cylinder-concave clearance between cylinder and notch board is 30-50mm, and above-mentioned two kinds of measures help the propelling of cane, reduces power consumption.

Notch board adopts lattice structure, and its grid distance is 14-18mm.

Sorting screen is hinged on the frame by four arms, drive to realize shake by eccentric wheel, and sieve nest is divided into two sections, and one section of corresponding notch board for leading portion is little sieve aperture, can sift out dust and broken foam, and another section is the big sieve aperture of back segment, and beans can fall, and cane is discharged on sieve aperture greatly.

Lysimachia sikokiana mechanism and to inhale the shell fan coaxial with cylinder, Lysimachia sikokiana mechanism be at the end of cylinder, inhale shell fan and Lysimachia sikokiana mechanism only a wall every, inhale the inlet scoop of shell fan and press close to sorting screen, so that with the also discharge of beans shell suction fan.

Feeding platform of the present utility model adopts the feeding mode that goes up, i.e. the peak of cylinder rotation tingia is lower than the feeding plane, and intake mechanism can adopt rubber strip feeding or dull and stereotyped artificial feeding automatically.

The general tractor with small four wheels that adopts 12 horsepowers of power source of the present utility model, perhaps 7.5 kilowatt motors drag.Transmission system is to pass to the drum shaft belt wheel by power source by belt, and drum shaft drives feeding belt wheel and sorting screen eccentric wheel more respectively.

When thresher is worked; the beans bar of band beans is filled into from the feeding platform; under the effect of roller plate tooth, beans separates from beanpod, is being mingled with the beans shell and the short stem that come off and is falling on the sorting screen by notch board; under the shake effect of sorting screen; dust and broken foam are sifted out, and beans and oversize are pushed ahead, and the beans shell is inhaled into discharge at the suction inlet place of inhaling the shell fan; beans falls into collection grain device by big sieve aperture, and short stem is discharged in the sorting screen termination.Purify the cane of beans,, discharge by Lysimachia sikokiana mechanism along screw propulsion.

The utlity model has characteristics such as simple in structure, easy enforcement, power consumption is little, suitable benefit is used based on the peasant household of the production-related contracting form of family, the production efficiency height, percentage of damage low (＜2%), clean rate height (＞99%), operating environment pollutes little, go up the feeding form owing to adopt, job safety is reliable.
