The utility model content
The purpose of this utility model is to provide a kind of can will directly be separated into corn corn seed, maize peel, corncob, and the bitubular of through threshing decortication formula three is separated husker sheller.
The technical solution of the utility model is: a kind of bitubular decortication formula three is separated husker sheller, comprise frame, the frame top is provided with feed hopper, the below of feed hopper is provided with the threshing tube that a mask has sieve aperture, the inner rotation of threshing tube is equipped with grain threshing roller, threshing tube below is provided with reciprocating sieve, described threshing tube is two major and minor threshing tubes arranged side by side, the front end of main threshing tube is communicated with the under shed of feed hopper, the rear end of main threshing tube is communicated with the rear end of secondary threshing tube, and the front opening of secondary threshing tube is for going out skin knockout mouth; Major and minor grain threshing roller is installed in respectively in the major and minor threshing tube, be equipped with many groups spike-tooth toward the outer side on the major and minor grain threshing roller, each end of organizing spike-tooth also is provided with the peeling rasp bar parallel with roll axis, the spike-tooth of respectively organizing on the main grain threshing roller is the helix shape that falls behind certain angle to the roller rear end on roll surface, the spike-tooth of respectively organizing on the secondary grain threshing roller is the helix shape that falls behind certain angle to the roller front end on roll surface.
Be provided with moving tooth on the peeling rasp bar of described main grain threshing roller in the rear end of main grain threshing roller, be provided with moving tooth in the front end of secondary grain threshing roller on the peeling rasp bar of described secondary grain threshing roller towards the roller outside towards the roller outside.
Described reciprocating sieve is double-deck reciprocating sieve, is made of the thin reciprocating sieve of thick reciprocating sieve in upper strata and lower floor.
The below of described double-deck reciprocating sieve is provided with dust absorption fan.
Also be provided with power input device on the described husker sheller, power input device is in transmission connection by one-way fashion friction clutch and main grain threshing roller.
The utility model is when work, corncob directly falls in the main threshing tube from feed hopper, the peeling rasp bar is peeled maize peel off on the main grain threshing roller, the corn seed is peeled the back by spike-tooth and spills from the sieve aperture of main threshing tube and drop on the reciprocating sieve, because the spike-tooth of respectively organizing on the main grain threshing roller is the helix shape that falls behind certain angle to the roller rear end on roll surface, corncob and maize peel are transported to main threshing tube rear end by the spike-tooth extruding together, and send into secondary threshing tube that main threshing tube rear end is communicated with in further carry out threshing work, corncob at secondary threshing tube once more through peeling, after the threshing, because the spike-tooth of respectively organizing on the secondary grain threshing roller is the helix shape that falls behind certain angle to the roller front end on roll surface, last remaining corncob and maize peel are dropped out by the skin knockout mouth that goes out that the spike-tooth extruding is transported to secondary threshing tube front end, accomplish that seed separates fully with core-skin.
In addition, reciprocating sieve is the double-deck reciprocating sieve that the thin reciprocating sieve by the thick reciprocating sieve on upper strata and lower floor constitutes, than the landing from the thick vibrations compass screen surface on upper strata of the big impurity of corn seed, the landing from the thin vibrations compass screen surface of lower floor of corn seed is fallen down and is siphoned away by dust absorption fan than the thin reciprocating sieve of the little impurity of corn seed from lower floor.
Major and minor threshing tube of the present utility model can carry out twice threshing to corn to be separated, and separates totallyer, and the peeling rasp bar on the grain threshing roller can directly be peeled maize peel off, has saved working time, has reduced labour intensity, uses convenient.
