Description

A kind of flexible differential husker sheller

Technical field

The utility model relates to agricultural mechanical field, specifically a kind of flexible differential husker sheller.

Background technology

Corn is one of Three major grain crops in the world, and China is in the world main Maize Production big country.Method of seed corn is the key link in harvesting work, and it has determined the damaged degree of corn seed, is a key link that guarantees the good harvest of corn high yield.At present, tradition adopts the husker sheller that hits principle design, and corn kernel breakage rate is higher, and corncob is difficult to retain intact, and it is complete that the seed at corn ear tip is difficult to threshing.The breakage of corn seed affects corn kernel short-term, long-term storage, suffers that damaged corn seed germination rate is low, the easy bacterium, infested, easily broken of mildewing, and reduces its market value and export value.Threshing operations is also an onerous toil, and threshing, after reducing harvest yield and corn quality late, even affects follow-up work.

Utility model content

Technical problem to be solved in the utility model be overcome in prior art that husker sheller causes that corn kernel breakage rate is high, threshing not exclusively and corncob be difficult to retain intact problem, a kind of flexible differential husker sheller is provided.

The utility model is to solve the problems of the technologies described above adopted scheme to be: a kind of flexible differential husker sheller, comprise frame, be fixed on the threshing chamber in frame, the knockout bucket that is located at the feeding hopper on threshing chamber input top and is located at threshing chamber output end, frame is provided with the lower skateboard that is divested seed for collecting threshing chamber, in described threshing chamber, be provided with threshing cylinder and the annular notch board that is located at threshing cylinder periphery by its rotation of driven by motor, the top of annular notch board is provided with along its axially extended opening, the inwall on described threshing chamber top is provided with along the leading line moving ahead for auxiliary propulsion corn ear of threshing chamber axial screw setting, on the outer peripheral face of described threshing cylinder, along it, be axially evenly interval with the spike-tooth that many rows move ahead for stirring corn ear, the setting straggly of each nail tooth makes it along threshing cylinder outer peripheral face, be the Spiral distribution consistent with the leading line hand of spiral, thereby arranging of described spike-tooth highly makes it promote when corn ear moves ahead corn ear to be squeezed between spike-tooth and annular notch board by threshing, the seed of sloughing by being provided with for supplying to slough the notch board hole that seed falls to lower skateboard on annular notch board, on the outer peripheral face of described threshing cylinder and spike-tooth, be all arranged with rubber case, reduce the mechanical damage of seed, reduce breakage rate.

Further, in every nail tooth, the height of each spike-tooth is initial from the position corresponding to feeding hopper, to the one end corresponding to knockout bucket, increase successively, the size setting of spike-tooth height and annular notch board internal diameter, corn ear can be advanced along gap between threshing cylinder and annular notch board and by threshing, in every nail tooth, the top of a spike-tooth of the most close knockout bucket is no more than 35mm apart from the distance of annular notch board inwall.Spike-tooth is back taper, and top, without corner angle, is arc surface, reduces the breakage rate that is divested corn kernel.

On spike-tooth and detachment roller, overlap rubber sleeve, leading line is also that rubber is made, and corn kernel has been carried out to good protection, has reduced greatly seed damaged.

Described annular notch board is totally enclosed type not, and the two ends of annular notch board are fixed on threshing chamber, and annular notch board is 270 ° of peripheries that are wrapped in threshing cylinder; The notch board hole of annular on notch board is random distribution, and the diameter in notch board hole is 18 ~ 20mm, guarantees that corn kernel can fall into threshing chamber bottom by notch board hole.

This husker sheller also comprises the sieve plate that is inclined at knockout bucket inside, the head end of sieve plate is corresponding with the output of threshing cylinder, the bottom of sieve plate is provided with the deflector being obliquely installed, and the end of deflector one end and sieve plate is accepted, and the other end extend into threshing chamber inside; The angle of the lower surface of described sieve plate and threshing cylinder central shaft is 15-20 °, sieve plate is for accepting the corncob of threshing chamber output output, corncob skids off knockout bucket along sieve plate, when corncob has been taken corn kernel out of, corn kernel leaks down by the sieve aperture arranging on sieve plate, and slides back to threshing chamber along deflector.

The operation principle of this husker sheller: corn ear is fed in threshing chamber from feeding hopper; corn ear can be along with the motion of threshing cylinder; the hand of spiral along leading line is pushed ahead; because the top of annular notch board is provided with along its axially extended opening; corn ear is by the shock of spike-tooth on the threshing cylinder of rotation; with annular notch board friction, form differential threshing again, the seed of sloughing is separated by the notch board hole on annular notch board.On the outer peripheral face of threshing cylinder and spike-tooth, be all arranged with rubber case, avoid the seed sloughed damaged, and guarantee the complete of corncob.

Beneficial effect: one, the utility model are in use, realized the repeatedly threshing of corn ear, in advance by the collision of spike-tooth on threshing cylinder and corn ear, make the seed on corn ear produce vibration and inertia force, thereby destruction seed is connected with corncob, next is the friction to corn ear by differing heights spike-tooth and annular notch board, form differential threshing, making it threshing efficiency improves, and because the parts that contact with corn kernel are provided with rubber sleeve, reduced corn kernel breakage rate.

Two, on the outer peripheral face of threshing cylinder, along it, be axially evenly interval with many nails tooth, when threshing cylinder rotates, the top of spike-tooth is forced threshing with certain speed to corn ear, and corn ear is pushed ahead with spike-tooth in spiral distribution, corncob is discharged from threshing chamber along the spiral thrust of spike-tooth, guarantee the integrality of corncob; And the height of each spike-tooth increases successively along the direction of propulsion of corn ear in every row, the spacing between spike-tooth top and annular notch board inwall reduces, and guarantees that the seed at corn ear tip also can be divested.
