352 and broken stalk rotating shaft driving pulley 360, oscillation bearing fitted shaft 354 is connected oscillation bearing 355, and the one of the fork 356
End connects oscillation bearing 355 by bearing pin, and the other end is rotatably connected at fork mounting seat 357, the upper end clamping of swing arm 358
On fork 356, the lower end of swing arm 358 is connected joint 359 with swing arm and is hinged, the other end and moving knife seat in swing arm connection joint 359
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 to adjust gap 3581 of hexagon socket head cap screw, swing arm 358 is rotated relative to fork 356
Certain angle is simultaneously locked.
Wherein, as shown in figure 9, the knife edge included angle of the both sides of cutting blade 322 is set to 60 degree, so sufficiently large cutting is being ensured
Swaging clamp phenomenon is avoided that in the case of face, while being provided with sawtooth per side tool sword, cutting efficiency can be improved.
Wherein, as shown in Figure 10,11, 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 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.
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 figs. 12-14, 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
Tightly, when needing to adjust the position of cutting blade 322 and moving knife seat 323, unscrew hexagon socket head cap screw, make the relative fork of swing arm 358
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 stalk, 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 12,14, the number of the hexagon socket head cap screw
Measure as two.
Wherein, as shown in Fig. 2 lower cutting table connecting rod 316 and level ground angle are 15 degree, lower cutting table had so both been can guarantee that
By property, prevent from encountering ground and damaging；Can also make to cut that stubble is relatively low and smooth, easily facilitate follow-up ploughing work.
Wherein, as shown in Figure 12,13, the hinge bar 3231 of L-shaped is fixed with the moving knife seat 323, hinge bar 3231
One right-angle side is welded in moving knife seat 323, and another right-angle side is articulated with swing arm connection one end of joint 359, so can be by swing arm
Swing is converted into the straight reciprocating motion of moving knife seat, eliminates the play up and down of moving knife seat, in turn simplify device structure, reduces
Processing cost.
When harvester header works, as shown in Fig. 3,6, the power of engine 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：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 band driven fork
356 do centering swings, and the swing arm 358 being connected on fork 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 do along cutting blade sliding groove 3211 and moving knife seat sliding groove 3212
Linear reciprocation is slided.During harvester advances, stalk is entered between the stationary knife head 321 of taper arranged in a straight line, linear reciprocation
The cutting blade 322 of slip forms cutting mechanism with stationary knife head 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
Rotate 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 adjustable fixed lower cutting table of cutting blade of the present invention, can cut and remaining stalk after ground cereal harvesting
Portion, alleviates the feed quantity of harvester, reduces machine loss and threshing load, improves Threshing；Cut stubble low and smooth
It is easy to arable land；Easily can easily adjust the position of cutting blade, it is ensured that the high efficiency of cutting and the crushing of stalk.
