356, which do centering, swings, and the swing arm 358 being connected on swing rod 356, which is also followed, does centering swing, because swing arm connects joint 359 1
End is articulated with the lower end of swing arm 358, and the other end is hinged moving knife seat 323, and the centering of swing arm 358 swings meeting push-and-pull moving knife seat 323 and does straight
Line reciprocatingly slides, and moving knife seat 323 drives cutting blade 322 to be done along cutting blade sliding groove 3211 and moving knife seat sliding groove 3212
Linear reciprocation is slided.During harvester advances, stalk enters between the stationary knife first 321 of taper arranged in a straight line, linear reciprocation
The cutting blade 322 of slip forms cutting mechanism with stationary knife first 321, so as to realize the cutting to stalk.
The operation principle of Sui Gan mechanisms 33 is as follows：3rd belt 349 drives broken stalk rotating shaft driving pulley 360 to rotate, fixed
Rotated with the broken stalk rotating shaft 331 of driving pulley 360, multiple broken stalk blades 3321 in broken stalk rotating shaft 331 around
Broken stalk rotating shaft 331 rotates at a high speed, and the stalk under lower cutting mechanism 32 is cut is involved in and smashed from the lower section of broken stalk rotating shaft 331,
So as to realize the crushing to stalk, the stalk after crushing is thrown out of the field at the rear of Sui Gan mechanisms 33 by centrifugal force, completes straw
Stalk returning to the field.
As shown in Figure 10,11,12,13, in addition to cat ladder 4, the cat ladder 4 includes side plate 41, connecting plate 42 and pedal 43,
Side plate 41 is L-shaped, and two blocks of side plates 41 are symmetrical arranged, and the long side of two blocks of side plates 41 is symmetrically provided with waist-shaped hole 411 as handrail, connection
