Section along the hatching gained of blade is isosceles trapezoid, and this hatching is parallel with the trapezoidal upper and lower end of blade body.(principle of this technological means is make cutterhead rotate rotating and all can use, and effect to be identical.）
Cutterhead is provided with the blade contiguous block; The blade contiguous block along the periphery of cutterhead evenly axisymmetricly; The both sides of each blade contiguous block respectively connect a blade.Plane, stationary knife place is between two blades on the same blade contiguous block.Spacing between two blades of plane, described stationary knife place to the same blade contiguous block is identical.
The blade assembly structure is through hole; Have the screw corresponding with this lead to the hole site on the described blade contiguous block, changeing at screw has bolt.(principle of this technological means is to be assemblied in blade on the cutterhead easily.）
Described drive unit is the engine of combine; Described linkage comprises gearbox and chain gear transmission structure; The sprocket wheel corresponding with described chain gear transmission structure is housed on the described cutter axis; The power take-off of described engine connects the power shaft of gearbox, and the output shaft of gearbox is by the sprocket wheel on the chain gear transmission structure connection cutter axis.(principle of this technological means is directly to adopt the power on the combine.）
Beneficial effect: after using the utility model, the stalk length that the cutterhead cutting obtains can be controlled in 8cm, and stalk is cut very brokenly, is conducive to throw and looses.
