Abstract
The invention discloses a corn threshing cutter, which comprises a cutter body and a cutter bar, wherein the cutter body is fixedly connected to a metal plate; the metal plate is taken as the blade-facing surface of the cutter body; a cutting edge angle alpha formed by the metal plate and the cutter body is 120+/-5 degrees. According to the corn threshing cutter disclosed by the invention, an appropriate cutting edge angle, sharpness degree and sufficient rigidity are realized, so that the corn threshing efficiency is increased effectively, the corn smashing rate is reduced, and the aim of threshing excellently, efficiently and completely is fulfilled.
Description
Technical field
The present invention relates to a kind of husker sheller special-purpose threshing cutter, particularly a kind of corn threshing knife.
Background technology
The single angle steel manufacture of the normal employing of threshing cutter of tradition husker sheller, blade angle is 90 °, in use, corn percentage of damage is higher; Also have the bending of the slab of employing to form, but cutting edge radius of corner is large, sharpness is inadequate, and rigidity is not good enough, causes threshing performance low.The threshing cutter of these two kinds of forms, due to fault of construction, result of use is bad.
Summary of the invention
The invention provides a kind of corn threshing knife, suitable blade angle and sharpness and enough rigidity, effectively improve corn threshing performance, reduces corn percentage of damage, reaches the object of high-quality, efficient, thorough threshing.
Above-mentioned purpose of the present invention is to realize by such technical scheme: corn threshing knife, comprise cutter hub, knife bar, described cutter hub is fixed with a metallic plate, described metallic plate is as the sword face of meeting of cutter hub, and the blade angle α that described metallic plate and cutter hub form is 120 ° ± 5 °.
Between described metallic plate and cutter hub, be provided with back up, metallic plate is band steel, and knife bar is fixed with screw rod.
A kind of corn threshing knife of the present invention, corn ear enters after threshing chamber, at the threshing cylinder rotating, with under relative static threshing cutter acting in conjunction, iblet is taken off, and reaches threshing object.Suitable blade angle and sharpness and enough rigidity, high threshing ratio and the low percentage of damage of assurance machine.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is corn threshing knife stereogram one of the present invention;
Fig. 2 is corn threshing knife stereogram two of the present invention.
Embodiment
As shown in Figure 1 and Figure 2, corn threshing knife, comprises cutter hub 1, knife bar 2, and cutter hub 1 is fixedly welded on knife bar 2, and screw rod 5 is fixedly welded on knife bar 2.Cutter hub 1 is angle steel.
Described cutter hub 1 is fixed with a metallic plate 2, and metallic plate 2 adopts band steel.Described metallic plate 2 is as the sword face of meeting of cutter hub 1.
Described metallic plate 2 is 120 ° ± 5 ° with the blade angle α of the vertical plane 1-1 formation of the cutter hub 1 of angle steel type.
Fixing welding back up 4 between the horizontal plane 1-2 of the cutter hub 1 of described metallic plate 2 and angle steel type, back up 4 adopts round steel.Back up 4 plays the effect of supporting fixed metal plate 2, thus fixing blade angle α.
Corn threshing knife of the present invention in the frame of husker sheller threshing cylinder side, keeps certain cylinder-concave clearance with threshing cylinder by screw rod 5 and self-regulation spring fitting.Corn ear enters husker sheller threshing chamber from charging aperture, under the rotary actuation of threshing cylinder, under impact, extruding and the twisting action of threshing edge of the present invention, iblet is taken off from corn ear, realizes threshing.Threshing cutter can move left and right under corn ear extruding force and spring force acting in conjunction, to change the cylinder-concave clearance between cutting edge and threshing cylinder, automatically adapts to the variation of corn ear diameter, reaches the object of high-quality, efficient, thorough threshing.
