Abstract
The invention discloses a straw clearing knife of a corn husker. The straw clearing knife is W-shaped and has sharp corners and circular arcs. Convex circular arcs on two sides of the knife body have a center distance of 70 to 75mm and a height of 38 to 45mm; a side sharp has a length of 95 to 100mm and a straight length of 38 to 42mm; the height between a middle concave circular arc and the side sharp wall is 15 to 20mm; a guide sharp has a downward height of 8 to 12mm; edge circular arcs have a center distance of 70 to 75mm; the length between the centers of the edge circular arcs on the two sides and the rear end of the knife body is 95 to 105mm; the knife body is 120 to 125mm wide; the middle concave circular arc has a radius of 55 to 65mm; the convex circular arcs on the left and right sides have a radius of 32 to 38mm; the circular arc of the guide sharp has a radius of 0.5 to 1.5mm; the edge circular arcs on the left and right sides have a radius of 22 to 28mm; and the guide sharp has a downward angle of 160 to 170 degrees. The straw clearing knife has the advantages of effectively cutting sundries at the tail end of the husker, such as straws, stem leaves and the like, and preventing the sundries entering a peeling roller and damaging the husker.
Description
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 straw clearing knife of corn husker.
Background technology
At present, in of home make harvest corn and the processing equipment, the debarker of the combined harvester of not threshing of peeling, its peeling mostly is and utilizes a pair of counterrotating peeling rollers, the peeling rollers kind has cast iron roll, rubber rollers, welding spiral metal peeling rollers etc., and cast iron roll is provided with the peeling nail, rotates the resistance of generation mutually by nail of the peeling on the cast iron rod 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 ofly after satisfying normal corn peeling needs, cut off corn husker terminal residual maize straw, cauline leaf and bract, prevent that it from entering the parts that result in blockage between the peeling rollers, i.e. straw clearing knife of corn husker.
Technical scheme of the present invention is: the straw clearing knife of corn husker cross section is the W type, band wedge angle and circular arc.Wherein convex surface center of arc in cutter hub both sides is 70～75mm apart from A1, cutter hub both sides convex surface center of arc height A 2 is 38～45mm, the distance A 3 of cutter hub rear end and sidepiece point of a knife is 95～100mm, the distance A 3 of cutter hub rear end and sidepiece point of a knife is 95～100mm, and side point length of straigh line A4 is 38～42mm; Middle part concave surface circular arc and side point wall height A 5 are 15～20mm, the guiding point height A 6 that has a down dip is 8～12mm, the centre-to-centre spacing A7 of left side cutting edge circular arc and right side cutting edge circular arc is 70～75mm, both sides cutting edge center of arc and cutter hub rear end length A 8 are 95～105mm, cutter hub width A9 is 120～125mm, middle part concave surface arc radius R1 is 55～65mm, left side convex surface arc radius R2 is 32～38mm, right side convex surface arc radius R3 is 32～38mm, the sharp arc radius R4 that leads is 0.5～1.5mm, left side rounded cutting edge radius R5 is 22～28mm, and right side rounded cutting edge radius R6 is 22～28mm, and the sharp tilt angled down α 1 that leads is 160 °～170 °.
The present invention adopts the good effect that produces after the technique scheme to be: the cutting edge circular arc of straw clearing knife of corn husker both sides (R5, R6) can cut off maize straw, cauline leaf and the bract of corn husker end effectively, the left and right side convex surface circular arc (R2, R3) that is pressed on the peeling rollers can prevent that maize straw, cauline leaf, bract from entering between the peeling rollers, thereby avoid stopping up corn husker, prevent the damage of corn husker.

Embodiment
As shown in Figures 1 to 4, straw clearing knife of corn husker is made the shape that the cross section is W type band wedge angle and circular arc by steel plate, wherein convex surface center of arc in cutter hub both sides is 70～75mm apart from A1, cutter hub both sides convex surface center of arc height A 2 is 38～45mm, the distance A 3 of cutter hub rear end and sidepiece point of a knife is 95～100mm, side point length of straigh line A4 is 38～42mm, middle part concave surface circular arc and side point wall height A 5 are 15～20mm, the guiding point height A 6 that has a down dip is 8～12mm, the centre-to-centre spacing A7 of left side cutting edge circular arc and right side cutting edge circular arc is 70～75mm, both sides cutting edge center of arc and cutter hub rear end length A 8 are 95～105mm, cutter hub width A9 is 120～125mm, middle part concave surface arc radius R1 is 55～65mm, and left side convex surface arc radius R2 is 32～38mm, and right side convex surface arc radius R3 is 32～38mm, the sharp arc radius R4 that leads is 0.5～1.5mm, left side rounded cutting edge radius R5 is 22～28mm, and right side rounded cutting edge radius R6 is 22～28mm, and the sharp angle of declination α 1 that leads is 160 °～170 °.
During the corn peeling machine operation, after corn ear entered debarker, the part made from bracteal leaf of corn, stalk and the cauline leaf that peel were discharged from outside the apparatus for peeling off, but the corn husker end still can more residual made from bracteal leaf of corn, stalk and cauline leaf.At this moment the cutting edge circular arc of straw clearing knife both sides (R5, R6) can further cut off these residues, the left and right side convex surface circular arc (R2, R3) that straw clearing knife is pressed on the peeling rollers can prevent effectively that made from bracteal leaf of corn, stalk and cauline leaf from entering between the peeling rollers, thereby avoid stopping up corn husker, prevent the damage of corn husker.
