Due to forming sealing space in grain storehouse 402, when generating negative pressure in separation bin 202,402 inside of grain storehouse is with separating Pressure differential will not be generated inside storehouse 202, suction ventilator 204 cannot form air-flow in grain storehouse 402, i.e., will not be by grain storehouse 402 Interior grain is pumped at suction ventilator 204, has been reached wind stopping device in the prior art and has been kept apart a part of space of separation bin 202 Come, avoid suction ventilator 204 that the grain in grain storehouse 402 is drawn to the purpose of suction ventilator 204.Due to eliminating wind stopping device, show Go out following advantageous effect：First, suction ventilator 204, separation bin 202 and the fitted position for pushing away the portions such as grain machine structure 4 are reduced, reduces vehicle Highly, prevent from scraping barrier during grain collecting vehicle traveling, reduce vehicle center of gravity；2nd, the wind stopping device saved is also reduced Coordinate the use of motor with it, it, can by reducing the requirement of engine 101 model so as to reduce 101 power demand of engine To save 101 cost of engine, mitigate complete vehicle weight；3rd, the blade of wind stopping device is thoroughly avoided by the feelings of grain crushing Condition.

Further, this programme is in a manner that screw auger 403 pushes grain to grain storehouse 402, screw auger 403 Radial dimension substantially reduces, and avoids grain storehouse 402 and raises separation bin 202 and suction ventilator 204；And since grain storehouse 402 shifts To one side, 402 peripheral obstacle of grain storehouse stops that the turnover door taking-up for less, being conveniently operated personnel's opening grain storehouse 402 is wherein deposited The grain of storage.

Further, grain storehouse is increased during pushing grain to grain storehouse 402 in order to avoid screw auger 403 402 internal pressures cause to promote difficulty, unidirectional relief valve 405 are installed on grain storehouse 402 so that the air pressure in grain storehouse 402 It excludes in time.

In order to prevent separation bin 202, to push away the space sealing formed between grain machine structure 4 and grain storehouse 402 bad, as benefit It fills, is respectively articulated on inner wall at left and right sides of 202 lower part of separation bin and is useful for separation bin 202 and pushes away what grain machine structure 4 was kept apart Sealing plate 206, the top of sealing plate 206 are respectively equipped with a limiting plate 207 to 206 /V of sealing plate, limiting plate 207 with it is right Answer it is corresponding respectively between sealing plate 206 extension spring 208 that corresponding sealing plate 206 is drawn to closure is installed, in extension spring 208 Stretching action under, two pieces of 206 steering horizontal states of sealing plate are mutually clamped, formed sealing partition plate, limiting plate 207 as resistance Stopper defines the rotation limit of sealing plate 206, and sealing plate 206 is prevented to be flipped up excessively；When grain is gathered in sealing plate 206 tops, more than the traction force of extension spring 208, sealing plate 206 is opened, and grain enters screw auger 403, extension spring 208 It resets, is again sealed off.

In the prior art, for drawing the suction grain functional component of grain with taking off grain for what grain was grilled into grain storehouse 402 Functional component is mutual indepedent, inhales grain functional component as the supplement for taking off grain functional component, but two independent functional components are also Include each independent corollary system, the structure both caused is numerous and jumbled, bulky, such as take off grain functional component usually require it is defeated Machine is sent to transmit grain, and the volume of conveyer is very huge.

In order to improve the problem, reduce vehicle volume, improve and receive grain efficiency, this programme use using inhale grain functional component as It is main, to take off the mentality of designing supplemented by grain functional component, remove bulky conveyer, only retain take off grain take off grain auger 305；Specific embodiment is：It is installed in 1 front end of chassis and holds together grain machine structure 3 for gather grain；Hold together grain machine structure 3 and grain It is connected between separating mechanism 2 by food sucking pipe 201, platform 102 is set in 1 front end of chassis, holding together grain machine structure 3 includes holding together shell 301, puts down Platform 102 and holding together between shell 301 is connected using parallel four-bar linkage 302, and the rear end for holding together shell 301 is hinged with thread bush 303, platform No. three motors 304 are hinged on 102, the shaft of No. three motors 304 is connected with thread bush 303 by the way of thread fitting；Hold together The front end of shell 301 is equipped with feed inlet 306, holds together in shell 301 to be equipped with to take off grain auger 305, food sucking pipe 201 and after holding together 301 inside of shell Side space connects.

It takes off grain auger 305 and shares two, the front end for taking off grain auger 305 is opened to the left and right sides respectively, and two are in splayed Set take off grain auger 305 realize using it is less take off grain auger 305 carry out it is large range of take off grain, can improve and take off grain effect Rate；It takes off and prismatic sub-material frame 309 is equipped between grain auger 305, prismatic sub-material frame 309 and hold together shell 301 and collectively form to take off grain auger 305 Outline border, take off grain auger 305 with cooperation and convey grain backward, the triangular structure of 309 forepart of prismatic sub-material frame is by grain point To taking off at grain auger 305 for both sides.

Grain scope is received in order to further expand, holds together the left and right sides of shell 301 and is respectively articulated with that there are one be used to take off grain to holding together Plate 310 is taken off in 301 front of shell, takes off plate 310 and is driven by the cylinder, under the action of cylinder, takes off plate 310 and be subject to lever principle and turn It is dynamic.

In use, the shaft of No. three motors 304 rotates, since No. three motors 304 cannot be rotated with thread bush 303, because This is rotated when shaft, and thread bush 303 is axially moveable compared with shaft, and thread bush 303 promotes shell 301 to connect parallel four at this time The control lower swing of linkage 302 adapts to the difference of grain piling height, holds together shell 301 forward in side-lower swing process, grain From feed inlet 306 into shell 301 is held together, grain auger 305 is taken off by grain so as to holding together the front side of shell 301 by what No. four motors 308 drove Push rear side to, the food sucking pipe 201 connected at this time with holding together 301 back space of shell, which is taken advantage of a situation, sucks grain in separation bin 202.

In the above-mentioned course of work, the transmission rate for taking off grain auger 305 is met as standard using the grain rate of taking off for taking off plate 310, Following relational expression can be drawn by establishing the mathematical model taken off grain auger 305 and taken off between plate 310：
