Have barrier avoiding function, by lifting harvester header, can easily avoid the barrier in front, so as to protect harvester header not by
Damage.
In order to reduce fluid pressure line and kinetic equation loss, manufacturing cost and use cost is reduced, lower cutting table hoist cylinder 361 is using single
Acting cylinder, during lifting lower cutting table by hydraulic system drive, lower lower cutting table when by lower cutting table deadweight decline.
When harvester header works, the power of electromotor via chain 341, driven sprocket 342, the first power transmission shaft 343, the
One belt wheel 344, the first belt 345, the second belt wheel 346, second driving shaft 347, the 3rd belt wheel 348, the 3rd belt 349 are passed successively
Pass.
The operation principle of lower cutting mechanism 32 is as follows：3rd belt 349 is matched somebody with somebody with driven fork driving pulley 352 and oscillation bearing
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 lift lower cutting table that the energy crushing straw and breakage-proof stalk of the present invention splashes, can cut and ground cereal
Remaining straw portion, alleviates the feed quantity of harvester after harvesting, reduces machine loss and threshing load, improves threshing effect
Really；Cut stubble it is low and smooth be easy to arable land；The cutting of straw and crush efficiency are high, and the straw of crushing will not splash；Lower cutting table can be with
Lifting is so as to controlling cutting height and being capable of avoiding obstacles protection equipment safety.
