One end of swing rod 356 connects oscillation bearing 355 by bearing pin, and the other end is rotatably connected at swing rod mounting seat 357, swing arm
358 upper end is connected on swing rod 356, and the lower end of swing arm 358 is be hinged with swing arm connecting joint 359, swing arm connecting joint 359
The other end is rotatably coupled with moving knife seat 323, and the hinge bar 3231 of L-shaped, hinge bar are fixed with the moving knife seat 323
3231 right-angle side is welded in moving knife seat 323, and another right-angle side is articulated with the one end of swing arm connecting joint 359, swing arm 358
Top be provided with adjustment gap 3581, by hexagon socket head cap screw it is elastic come control adjustment gap 3581 width, make swing arm 358
The relative swing rod 356 of energy turns an angle and locked.
Wherein, the knife edge included angle of the both sides of cutting blade 322 is set to 60 degree, is so ensureing the feelings of sufficiently large cut surface
Swaging clamp phenomenon is avoided that under condition, while sawtooth is provided with 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.
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
Swing 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
The high efficiency of cutting stalk is ensure that, at the same it is simple in construction, the position of quick adjustment cutting blade 322 is furthermore possible to, operation is just
Victory, locking are 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, lower cutting table connecting rod 316 and level ground angle are 15 degree, so both can guarantee that lower cutting table by property,
Prevent from encountering ground and damaging；It can also make to cut that stubble is relatively low and smooth, easily facilitate follow-up ploughing work.
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.
When harvester header works, the power of engine via chain 341, driven sprocket 342, the first power transmission shaft 343,
First pulley 344, the first belt 345, the second belt wheel 346, second driving shaft 347, the 3rd belt wheel 348, the 3rd belt 349 according to
Secondary transmission.
The operation principle of lower cutting mechanism 32 is as follows：3rd belt 349 is with driven fork driving pulley 352 and oscillation bearing
Fitted shaft 354 rotates, and coordinates the oscillation bearing 355 in oscillation bearing fitted shaft 354 to wave rotation therewith, so as to drive
Swing rod 356 does centering and swung, and the swing arm 358 being connected on swing rod 356, which also follows, does centering swing, due to swing arm connecting joint
359 one end are 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 is swung can push-and-pull moving knife seat
323 do linear reciprocation slip, and moving knife seat 323 drives cutting blade 322 to be slided along cutting blade sliding groove 3211 and moving knife seat
Groove 3212 does linear reciprocation slip.During harvester advances, stalk enters between the stationary knife first 321 of taper arranged in a straight line,
The cutting blade 322 that linear reciprocation is slided 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.
As shown in Figure 15,16,17, in addition to cat ladder 4, the cat ladder 4 include side plate 41, connecting plate 42 and pedal 43, side
Plate 41 is L-shaped, and two blocks of side plates 41 are symmetrical arranged, and the long side of two blocks of side plates 41 is symmetrically provided with waist-shaped hole 411 and is used as handrail, connection
The both ends of plate 42 connect the short side of two blocks of side plates 41, and be provided with through hole 421 on the thickness of slab longitudinal direction of connecting plate 42 inserts for installation locking
Pin, polylith pedal 43 are uniformly arranged between two blocks of side plates 41, and the both ends of every piece of pedal 43 connect the long side of two blocks of side plates 41,
For pedal 43 from inboard to being sloped downwardly outside, the angle of inclined plane and horizontal plane is 30 degree, and the inclined plane of pedal 43, which is provided with, cuts
Face is the tread plate 431 of triangle, and the cat ladder 4 is articulated with the outer side edges of bottom plate of driving cab by the hinge of its top installation
Edge.
Wherein, it is for more comfort and convenient when driver rides, on pedal 43 that pedal 43, which sets the inclined plane at 30 degree of angles,
Section is set to be used to improve skidproof effect guarantee safety for the tread plate 431 of triangle；Waist-shaped hole 411 is provided with side plate 41 to use
Make handrail, both save material and space, improve security and convenience during climbing cat ladder again.
The cat ladder 4 can be used for driver safety and easily climb into driver's cabin, and and can is used as safety barrier, protection
Driver will not fall away from driver's cabin because of accident.When driver needs to enter driver's cabin, downwardly turn over cat ladder 4 by its
Put down, you can for climbing；After driver enters driver's cabin, cat ladder 4 is flipped up, is passed through afterwards using locking latch in place
