Sympodium 354 rotates, and coordinates the oscillation bearing 355 in oscillation bearing fitted shaft 354 to wave rotation therewith, so as to band driven fork
356 do centering swings, and the swing arm 358 being connected on fork 356 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 do along cutting blade sliding groove 3211 and moving knife seat sliding groove 3212
Linear reciprocation is slided.During harvester advances, straw is entered between the stationary knife head 321 of the taper of linear array, linear reciprocation
The cutting blade 322 of slip forms cutting mechanism with stationary knife head 321, so as to realize the cutting to straw.
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
Rotate with the broken stalk rotating shaft 331 of driving pulley 360, the multiple broken stalk blade 3321 in broken stalk rotating shaft 331 around
Broken stalk rotating shaft 331 rotates at a high speed, and the straw under lower cutting mechanism 32 is cut is involved in and smashes from the lower section of broken stalk rotating shaft 331,
So as to realize the crushing to straw, the straw after crushing is thrown out of the field at the rear of Sui Gan mechanisms 33 by centrifugal force, completes straw
Stalk also field.
The harvester of the fixed lower cutting table that the breakage-proof stalk of the present invention splashes, can cut and remaining after ground cereal harvesting
Straw portion, alleviates the feed quantity of harvester, reduces machine loss and threshing load;Cut stubble it is low and smooth be easy to arable land;Straw
Stalk crush efficiency is high, and broken stalk will not splash.
