The width in gap 3581, enables the relative fork 356 of swing arm 358 to turn an angle and lock.
Wherein, the knife edge included angle of the both sides of cutting blade 322 is set to 60 degree, so in the situation for ensureing sufficiently large facet
Under be avoided that swaging clamp phenomenon, while being provided with sawtooth per side tool sword, cutting efficiency can be improved.
Wherein, the fix bar 318 of welding makes lower cutting table connecting rod 316, propons, fix bar 318 constitute stable triangle,
Ensure that the solid and reliable of structure, it is ensured that the height for cutting stubble is all consistent, cut that stubble is low and smooth to easily facilitate follow-up ploughing work.
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 straw smashes more uniform, raising crushing effect, broken stalk blade 3321 in per 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 can be sent out unavoidably machine with stationary knife head 321
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 for adjusting moving knife seat 323.As shown in Figure 12,13, adjustment gap 3581 is provided with the top of swing arm 358, by interior
The elastic width to control to adjust gap 3581 of hex bolts, enables the relative fork 356 of swing arm 358 to turn an angle and lock

356 outwardly or inwardly turn an angle, and determine that cutting blade 322 and moving knife seat 323 are moved to after correct position, then in tightening
Hex bolts, swing arm 358 is fixed and is locked on fork 356.This design can ensure that cutting blade 322 all the time in suitable
Position, so as to ensure that the high efficiency of cutting straw, while simple structure, is furthermore possible to quickly adjust the position of cutting blade 322
Put, simple operation, locking is firm.
In order that swing arm 358 is locked on fork 356 more firmly, and as shown in figure 12, the quantity of the hexagon socket head cap screw
For two.
When harvester header works, as shown in Fig. 3,6, the power of electromotor is via chain 341, driven sprocket 342, first
Power transmission shaft 343, the first belt wheel 344, the first belt 345, the second belt wheel 346, second driving shaft 347, the 3rd belt wheel the 348, the 3rd
Belt 349 is transmitted successively.
The operation principle of lower cutting mechanism 32 is as follows：As shown in Fig. 3,5, the 3rd belt 349 is with driven fork driving pulley 352
And oscillation bearing fitted shaft 354 rotates, the oscillation bearing 355 in oscillation bearing fitted shaft 354 is coordinated to wave rotation therewith,
Swing so as to band driven fork 356 does centering, the swing arm 358 being connected on fork 356 is also followed does centering swing, because swing arm connects
Connect the one end of joint 359 and be articulated with the lower end of swing arm 358, the other end is hinged moving knife seat 323, and the centering meeting of the swing push-and-pull of swing arm 358 is moved
Tool rest 323 does linear reciprocation slip, and moving knife seat 323 drives cutting blade 322 along cutting blade sliding groove 3211 and moving knife seat
Sliding groove 3212 does linear reciprocation slip.Harvester advance during, straw enter linear array taper stationary knife head 321 it
Between, the cutting blade 322 that linear reciprocation is slided 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：As shown in Fig. 3,5,8, the 3rd belt 349 drives broken stalk rotating shaft drive belt
Wheel 360 rotates, and the broken stalk rotating shaft 331 for being fixed on driving pulley 360 is rotated with, multiple broken in broken stalk rotating shaft 331
Stalk blade 3321 rotates at a high speed around broken stalk rotating shaft 331, and the straw under lower cutting mechanism 32 is cut is under broken stalk rotating shaft 331
Side is involved in and smashes, and so as to realize the crushing to straw, the straw after crushing is thrown out of the rear of Sui Gan mechanisms 33 by centrifugal force
Field, complete straw-returning.
The uniform fixed lower cutting table of the crushed stalk of the present invention, can cut and remaining straw after ground cereal harvesting
Portion, alleviates the feed quantity of harvester, reduces machine loss and threshing load, improves Threshing；Cut the height energy of stubble
Be consistent, cut stubble it is low and smooth be easy to arable land；Crushed stalk is uniform.
