Description

Eccentric grass cleaning roll of corn husker

Technical field

The invention belongs to corn harvesting machine and manufacture field, relate to the clear careless device of a kind of corn husker, relate in particular to a kind of eccentric grass cleaning roll of corn husker.

Background technology

At present, in of home make harvest corn and the processing equipment, the combined harvester debarker peeling of not threshing of peeling mostly is and utilizes a pair of tangent counterrotating peeling rollers, the peeling rollers kind has cast iron roll, rubber rollers, welding spiral metal peeling rollers etc., cast iron roll is provided with the peeling nail, rotate the resistance of generation mutually by the peeling on cast iron rod nail and two rollers during work, the bract of corn ear is torn, utilize the strength of mutual extrusion that cauline leaf is discharged apparatus for peeling off; Welding spiral metal peeling rollers is a helical form, and fruit ear is transferred out apparatus for peeling off by the thrust of the spiralization on the welding spiral metal peeling rollers; Then be provided with the spiral cushion rubber on the rubber peeling rollers, the thrust that the spiral rotation that fruit ear is formed by cushion rubber on the rubber rollers forms is transferred out apparatus for peeling off.Because two peeling rollers of configuration are circle, the rotation time space is constant substantially mutually, the Lysimachia sikokiana space is very little, the Lysimachia sikokiana weak effect, a large amount of maize straws, cauline leaf and bract are not excluded outside the device when arriving the peeling rollers end yet, are blocked in the peeling rollers end easily, easy to clean not, cause the peeling rollers wearing and tearing, the bearing sintering finally can cause the corn peeling machine host to damage.

Summary of the invention

The object of the present invention is to provide a kind of after satisfying normal corn peeling needs, the maize straw, cauline leaf and the bract that remain in the corn husker end constantly are squeezed and discharge, and utilize terminal fluting once more it to be forced to draw stem, be convenient to the eccentric straw clearing roller that residue is discharged corn husker.

Technical scheme of the present invention is: eccentric grass cleaning roll of corn husker, be eccentric hollow columnar form, and cylinder one side is provided with eccentric grove, and periphery is provided with careless clearly groove, and one end is provided with the pin hawk groove.

Wherein eccentric grove outer surface and straw clearing roller centre-to-centre spacing A1 are 20～30mm; Eccentric grove upper surface and straw clearing roller upper surface distance A 2 are 10～20mm; Eccentric grove lower surface and straw clearing roller lower surface distance A 3 are 10～20mm; Eccentric grove center and straw clearing roller centre-to-centre spacing A5 are 10～20mm; Straw clearing roller length A 11 is 120～145mm, and overall diameter D1 is 60～80mm, and end diameter D2 is 56～76mm, and diameter of bore D3 is 30～35mm, and eccentric grove arc radius R1 is 35～40mm.

Clear careless groove Radius A of the horizontal end 4 is 28～38mm, and width A8 is 4～7mm, and vertically end Radius A 9 is 28～38mm, and circumference angle α 1 is 12 °～20 °, and initial angle α 3 is 12 °～20 °, and the initial angle α 2 of adjacent two clear careless troughed belts is 60 °～100 °.

Pin hawk slot length A6 is 60mm, and width A7 is 10mm, and degree of depth A10 is 9mm, and left and right termination arc radius R2, R3 are 5mm.

The present invention adopts the good effect that produces after the technique scheme to be: eccentric straw clearing roller can make the stalk, cauline leaf and the bract that remain in the debarker end constantly be squeezed and discharge, and utilize terminal fluting once more it to be forced to draw stem, be convenient to residue and discharge debarker.

Embodiment

By Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, make the eccentric grass cleaning roll of corn husker of eccentric structure by magnesium iron, be eccentric hollow columnar form, cylinder one side is provided with eccentric grove, and periphery is provided with careless clearly groove, and one end is provided with the pin hawk groove.Wherein eccentric grove outer surface and straw clearing roller centre-to-centre spacing A1 are 20～30mm; Eccentric grove upper surface and straw clearing roller upper surface distance A 2 are 10～20mm; Eccentric grove lower surface and straw clearing roller lower surface distance A 3 are 10～20mm; Eccentric grove center and straw clearing roller centre-to-centre spacing A5 are 10～20mm; Straw clearing roller length A 11 is 120～145mm, and overall diameter D1 is 60～80mm, and end diameter D2 is 56～76mm, and diameter of bore D3 is 30～35mm, and eccentric grove arc radius R1 is 35～40mm.Clear careless groove Radius A of the horizontal end 4 is 28～38mm, and width A8 is 4～7mm, and vertically end Radius A 9 is 28～38mm, and circumference angle α 1 is 12 °～20 °, and initial angle α 3 is 12 °～20 °, and the initial angle α 2 of adjacent two clear careless troughed belts is 60 °～100 °.Pin hawk slot length A6 is 60mm, and width A7 is 10mm, and degree of depth A10 is 9mm, and left and right termination arc radius R2, R3 are 5mm.
