Wherein, the knife edge included angle of the both sides of cutting blade 322 is set to 60 degree, is so ensureing the situation of sufficiently large cut surface Under be avoided that swaging clamp phenomenon, while be 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 form stable triangle, It ensure that the solid and reliable of structure, ensure 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 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.
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.
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 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.
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 pass 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 as to driven fork 356, which do centering, swings, and the swing arm 358 being connected on swing rod 356, which also follows, does centering swing, due to swing arm connecting 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 done directly 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.
