323 are rotatably coupled, and the hinge bar 3231 of L-shaped, the right-angle side welding of hinge bar 3231 are fixed with the moving knife seat 323
In moving knife seat 323, another right-angle side is articulated with swing arm connection one end of joint 359, and the top of swing arm 358 is provided with adjustment gap
3581, by the elastic width to control adjustment gap 3581 of hexagon socket head cap screw, swing arm 358 is rotated relative to swing rod 356
Certain angle is simultaneously locked；
As shown in Fig. 2,5, the lower cutting table elevating mechanism 36 includes lower cutting table hoist cylinder 361, lower cutting table hoist cylinder
Lower cutting table connecting rod stull is fixed at seat 363 under the seat of honour 362, lower cutting table hoist cylinder, the lower cutting table hoist cylinder seat of honour 362
On 317, seat 363 is fixed on preceding pars basilaris pontis under the lower cutting table hoist cylinder, and the cylinder barrel of the lower cutting table hoist cylinder 361 is hinged
In seat 363 under lower cutting table hoist cylinder, the piston rod of the lower cutting table hoist cylinder 361 is articulated with the lower cutting table hoist cylinder seat of honour
362。
Wherein, as shown in Figure 10, the knife edge included angle of the both sides of cutting blade 322 is set to 60 degree, is so ensureing sufficiently large
Swaging clamp phenomenon is avoided that in the case of cut surface, while being provided with sawtooth per side tool sword, cutting efficiency can be improved.
Wherein, as shown in Figure 11,12, each broken stalk blade 3321 is removably mounted on broken stalk rotating shaft 331 by bolt
On, so it is easy to carry out quick-replaceable after broken stalk blade 3321 is passivated.
Wherein, in order that stalk smashes more uniform, raising crushing effect, broken stalk blade 3321 in every group of broken stalk knife 332
With 3321 one-tenth 60 degree of angles of broken stalk blade in the broken stalk knife 332 of adjacent sets.
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.
Using after certain hour, because the reason such as abrasion vibrations, cutting blade 322 first with stationary knife 321 can be sent out machine unavoidably
The skew of raw initial position, causes cutting efficiency to decline.So it is accomplished by periodically adjusting the position of cutting blade 322, that is,
Need the position of adjustment moving knife seat 323.Adjustment gap 3581 is provided with the top of swing arm 358, by the elastic of hexagon socket head cap screw
To control to adjust the width in 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, after determining that cutting blade 322 and moving knife seat 323 move 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 all the time in suitable position, so as to ensure
The high efficiency of cutting stalk, while simple structure, is furthermore possible to quickly adjust the position of 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 the stop angle bar 319 in the setting of the rear portion of block cover 314 is prevented from crushing is under the action of the centrifugal force
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 319 is welded in lower cutting table connecting rod 316 and plays a part of reinforcement.
Wherein, the lower cutting table elevating mechanism 36 for being acted by lower cutting table hoist cylinder 361, is needing to adjust cutting height
When, the length for controlling the piston rod of lower cutting table hoist cylinder 361 to stretch out.Additionally, 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 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 band driven fork
356 do centering swings, and the swing arm 358 being connected on swing rod 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 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 first with stationary knife 321 forms cutting mechanism, 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, 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 stalk 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 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 also field.
The harvester of the lift lower cutting table that crushed stalk of the invention is uniform and breakage-proof stalk splashes, 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 being adjusted promptly so as to ensure crushed stalk efficiency high, crushing uniform, broken stalk will not splash；Lower cutting table can be with
Lifting is so as to control cutting height and being capable of avoiding obstacles protection equipment safety.
