To picking up below cutter shaft, these straws are enable smoothly to be picked up.
In use, line shaft drives main-gear box 7 by main transmission universal drive shaft 200 after tractor, main-gear box 7 passes through the
One output shaft 72 and the second output shaft 73 drive to pick up driving pulley 81 and crush driving pulley 91 and rotated respectively, and then drive and pick up
Pick up cutter shaft 21 and crush cutter shaft 31 and rotate, pickup cutter shaft 21 and the crushing rotating speed of cutter shaft 31 is reached 2220 revs/min, pick up hammer
The straw of the high-speed impact of pawl 22 tiling on the ground, preliminary crushing straw, and using the air circulation that rotation is formed at a high speed, will
Straw volume after preliminary crushing is taken in pickup portion 2, and hammers the synchronous axial system of pawl 22 into shape with picking up, and is picking up at stationary knife group 23, straw
It is crushed again, then straw enters smashing portion 3, and in the case where crushing hammer leaf 32 and crushing the collective effect of stationary knife group 33, straw is again
Secondary pulverized, the straw for reaching returning to the field requirement passes through from broken sieve 4, completes to return crop stocks to the field.Larger-size straw falls on broken
On sieve 4, hammer leaf 32 is crushed again and is crushed, the straw that the detent projection 411 being especially broken on sieve 4 stops, crushes hammer leaf
32 coordinate with detent projection 411, and the straw of stop is crushed again, and straw has all reached returning to the field substantially after repeatedly crushing
It is required that.
Embodiment two
As shown in Figure 10, the present embodiment two and embodiment one are essentially identical, and something in common repeats no more, and difference exists
