The seat 363 under lower cutting table hoist cylinder, the piston rod of the lower cutting table hoist cylinder 361 are articulated with the lower cutting table hoist cylinder seat of honour
362。
Wherein, the knife edge included angle of the both sides of cutting blade 322 is set to 60 degree, is so ensureing the situation of sufficiently large cut surface
Under be avoided that swaging clamp phenomenon, while be provided with sawtooth per side tool sword, cutting efficiency can be improved.
Wherein, each broken stalk blade 3321 is removably mounted in broken stalk rotating shaft 331 by bolt, is so easy to broken
Stalk blade 3321 carries out quick-replaceable after being passivated.
Wherein, in order that stalk smashes more uniform, crushing effect is improved, broken stalk blade 3321 in every group of broken stalk knife 332
With broken stalk blade 3321 in the broken stalk knife 332 of adjacent sets into 60 degree of angles.
Wherein, the external part of broken stalk blade 3321 is provided with chamfering and forms blade, and chamfering is located at the outside of broken stalk blade 3321,
The crush efficiency of broken stalk can be improved.
After machine uses certain time, because reason, the cutting blade 322 such as abrasion vibrations can be sent out unavoidably with stationary knife first 321
The skew of raw initial position, causes cutting efficiency to decline.The position of periodically adjustment cutting blade 322 is thus needed, that is,
Need the position of adjustment moving knife seat 323.Adjustment gap 3581 is provided with the top of swing arm 358, passes through the elastic of hexagon socket head cap screw
To control the width in adjustment gap 3581, the swing rod 356 relatively of swing arm 358 is set to turn an angle and lock, when needing to adjust
During the position of cutting blade 322 and moving knife seat 323, unscrew hexagon socket head cap screw, make swing arm 358 with respect to swing rod 356 outwardly or inwardly
Turn an angle, determine cutting blade 322 and after moving knife seat 323 is moved to correct position, then tighten hexagon socket head cap screw, will put
Arm 358 is fixed and is locked on swing rod 356.This design can ensure that cutting blade 322 is in suitable position all the time, so as to ensure
The high efficiency of cutting stalk, at the same it is simple in construction, it is furthermore possible to the position of quick adjustment cutting blade 322, simple operation, lock
It is tight firm.
In order that swing arm 358 is locked on swing rod 356 more firmly, the quantity of the hexagon socket head cap screw is two.
Wherein, the hinge bar 3231 of L-shaped is fixed with the moving knife seat 323, a right-angle side of hinge bar 3231 is welded in
Moving knife seat 323, another right-angle side are articulated with the one end of swing arm connecting joint 359, so the swing of swing arm can be converted into moving knife
The straight reciprocating motion of seat, the play up and down for eliminating moving knife seat, in turn simplify device structure, reduce processing cost.
Wherein, the stalk after crushing can be prevented under the action of the centrifugal force in the stop angle bar 318 that the rear portion of block cover 314 is set
Splash backward, avoid broken stalk from falling into transmission system and hydraulic system damage machine, also avoiding, which influences pilot's line of vision, leads to a disaster；
In addition stop that angle bar 318 is welded in lower cutting table connecting rod 316 and plays a part of reinforcement.
Wherein, the lower cutting table elevating mechanism 36 acted by lower cutting table hoist cylinder 361, needing to adjust cutting height
When, the length of the piston rod stretching of control lower cutting table hoist cylinder 361.In addition, lower cutting table elevating mechanism 36 also has barrier avoiding function,
By lifting harvester header, the barrier in front can be easily avoided, so as to protect harvester header to be not damaged by.
When harvester header works, the power of engine is 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 pass 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 driven fork
356, which do centering, swings, and the swing arm 358 being connected on swing rod 356, which also follows, does centering swing, due to swing arm connecting 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 done directly
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.
The stalk of the present invention crushes the harvester for the lift two cutting tables that uniform and breakage-proof stalk splashes, and can cut and crush paddy
Remaining stalk portion after thing harvesting, alleviates the feed quantity of harvester, reduces machine loss and threshing load, can easily just
The position of cutting blade is adjusted promptly so as to ensure the high efficiency of stalk cutting and crush uniformly, and broken stalk will not splash；Lower cutting table
Can lift so as to control cutting height and can avoiding obstacles protection equipment safety.
