The swing of swing arm, can so be converted into the straight reciprocating motion of moving knife seat, eliminate the play up and down of moving knife seat by end, and simple
Change device structure, reduce processing cost.
(9) harvester that uniform and breakage-proof stalk splashing two cutting tables linkage is crushed with cat ladder stalk of the invention, after block cover
The stop angle bar that portion is set can prevent the stalk after crushing from splashing backward under the action of the centrifugal force, it is to avoid broken stalk falls into power train
System and hydraulic system damage machine, also avoid influence pilot's line of vision from leading to a disaster；In addition stop that angle bar is welded in lower cutting table company
Extension bar plays a part of reinforcement.
(10) harvester that uniform and breakage-proof stalk splashing two cutting tables linkage is crushed with cat ladder stalk of the invention, lower cutting table leads to
Cross gangbar follow upper header lifting linkage so that control cutting height and can avoiding obstacles protection equipment safety, together
When it is energy-saving, reduce manufacture and use cost.
(11) harvester that uniform and breakage-proof stalk splashing two cutting tables linkage is crushed with cat ladder stalk of the invention, cat ladder is stepped on
Plate sets the inclined plane at 30 degree angles to be that for more comfort and convenient when driver is foot-operated, section preventing for triangle is set on pedal
Draw runner is used to improve skidproof effect guarantee safety；Waist-shaped hole is provided with side plate as handrail, material and space is both saved, improved again
Security and convenience during climbing cat ladder.
(12) harvester that uniform and breakage-proof stalk splashing two cutting tables linkage is crushed with cat ladder stalk of the invention, setting is climbed
Ladder, which can be used for driver safety, easily to be climbed and enters driver's cabin, and safety barrier, protection driver are can serve as again will not be because of meaning
Fall away outside from driver's cabin.When driver needs to enter driver's cabin, downwardly turn over cat ladder and put down, you can for climbing
Climb；After driver enters driver's cabin, cat ladder is flipped up, connecting plate and driver's cabin bottom is passed through using locking latch afterwards in place
Plate, makes cat ladder be fixed on bottom plate of driving cab, as safety barrier.In addition, after cat ladder is flipped up, also reducing driver's cabin
Overall width, improve harvester by property.

Under be avoided that swaging clamp phenomenon, while being 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 broken stalk blade 3321 in more uniform, raising crushing effect, 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 formation blade, and chamfering is located at the outside of broken stalk blade 3321,
The crush efficiency of broken stalk can be improved.
Machine was used after certain time, because the reason such as abrasion vibrations, cutting blade 322 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 so accomplished by, 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 for adjusting gap 3581, swing arm 358 is set to turn an angle and lock with respect to swing rod 356, 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 that cutting blade 322 and moving knife seat 323 are moved to after 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 is articulated with swing arm connection one end of 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, it is to avoid broken stalk falls into transmission system and hydraulic system damages machine, also avoid influence pilot's line of vision from leading 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.
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 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 that with driven fork
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.
