Description

Husker sheller

The utility model belongs to agricultural mechanical field, relates to corn harvesting machine, particularly a kind ofly can divest the husker sheller that the corn ear bract can be taken off the multiple operation of corn ear seed again, and it can also be applied to corn combine.

Present harvest corn operation, mostly be will results corn ear, manually divest behind the fruit ear bract again with artificial or thresher and take off corn kernel on the corn ear, efficiency is low, intensity is big, gathers in the crops untimely.Existing corn combine, what have is equipped with the peeling procedure that divests the corn ear bract, the shortcoming that have complex structure, cost an arm and a leg, power consumption is big, operating cost is high and the bract walnut hulling rate is low, the seed breakage rate is high.Tentatively overcome above-mentioned shortcoming though formerly propose the Chinese patent application of patent application and number be the corn ear debarker of 97233945.0 documents record, threshing operations still needs to use in addition thresher or artificial.

The purpose of this utility model is further to overcome above-mentioned shortcoming, provide a kind of simple in structure, cost is low, use divested corn ear bract easy to maintenance and take off the husker sheller of the multiple operation of corn ear seed.

The utility model is made up of frame, peeling procedure, ear forwarder, separating mechanism and transmission mechanism.Peeling procedure of the present utility model and separating mechanism are installed on the same frame, and to connect by ear forwarder be a compound operation machine that can divest the corn ear bract and take off the corn ear seed, and outer cover is equipped with in the outside.The transmission of power that transmission mechanism then provides motive power such as electromotor, internal combustion engine, tractor and agricultural vehicle etc. is to each rotatable parts.Peeling procedure of the present utility model is made of the peeling rollers assembly in groups more than a group, every group of peeling rollers assembly is made up of two rollers, one of them is a smooth roll, the peeling roller shell that has along the equally distributed helical groove of circumference axially is housed on the peeling roll shaft of another peeling rollers, and block plate is equipped with at two ends.The peeling roller shell is a cylindrical sleeves, thickness be 15 millimeters to 100 millimeters, make with wear resistant elastic material.Have helical groove on the peeling roller shell excircle and evenly distribute, have the helical spline that matches with the peeling roll shaft on the inner hole surface along circumference.The helical groove helical pitch of peeling roller shell is 600 millimeters to 1000 millimeters, and the degree of depth is 3 millimeters to 25 millimeters, and the arc length on the circumference is 10 millimeters to 40 millimeters.It is also opposite that each peeling rollers direction of rotation that the utility model peeling procedure is adjacent, corresponding peeling rollers put the helical groove rotation direction that has.The peeling rollers group of peeling procedure top is provided with rib pads, is contained in respectively between peeling procedure both sides and adjacent two smooth rolls and adjacent two tops of being equipped with between the peeling rollers of peeling roller shell, and the gap is 5 millimeters to 15 millimeters between rib pads and the peeling procedure moving component.Feeding hopper is equipped with in hood of the present utility model top; away from the hood below the feeding hopper of separating mechanism one side the fruit ear plate washer being housed; this fruit ear baffle plate tilts to become 5 ° to 20 ° inclination angles with vertical guide to the fruit ear direction of motion, and the gap between fruit ear plate washer and the peeling procedure moving component is 5 millimeters to 20 millimeters.Be provided with ear forwarder between peeling procedure of the present utility model and the separating mechanism, interior the exporting between the import of separating mechanism corn ear from the peeling procedure corn ear of ear forwarder is equipped with deflector apron.

During work, the corn ear of the band bract that enters from the utility model feeding hopper because the guiding of fruit ear baffle plate and rib pads, drops on the peeling rollers of one group of peeling rollers group of peeling procedure.Two peeling rollers of this group are done the rotation that angular speed numerical value is identical and direction is opposite; under the effect of helical groove; divest the corn ear bract; bract is discharged from the peeling rollers below; the corn ear that divests bract simultaneously moves to the peeling procedure outlet and enters ear forwarder; by deflector apron corn ear is caused separating mechanism, separate discharge with corncob after deviating from corn kernel.Thereby finished task of the present utility model.

Peeling procedure of the present utility model also can be used for the peeling procedure of corn combine.

The utility model is compared with the peeling procedure of existing corn husker or corn combine, have bract walnut hulling rate height, seed loss less, simple in structure, low cost of manufacture, maintenance is easy to use and can once finish the multiple operation that divests the corn ear bract and take off the fruit ear seed.
