One, adjust the shaft rotation of 3: No. three motors 304 of grain machine structure, the relative distance generation of shaft and thread bush 303 Variation makes shaft push the Forward of thread bush 303 or retreat, and thread bush 303 drives shell 301 to put around parallel four-bar linkage 302 It is dynamic, to adjust the height and front-rear position of shell 301, to be accurately collected to the grain on dring yard；

Two, hold together grain: taking off grain auger 305 for two and rotate, in the frame for holding together shell 301 and prismatic sub-material frame 309 surrounds jointly It is interior, grain is pushed to the suction grain mouth of food sucking pipe 201 from feed inlet 306 to, by 307 structure of inclined-plane for holding together shell 301, grain is along tiltedly Face 307 is moved upward to closer to the position for inhaling grain mouth, is more convenient food sucking pipe 201 and is inhaled grain；

Three, inhale grain: No.1 motor 205 drives suction ventilator 204 to form negative pressure in separation bin 202, is connected with separation bin 202 It is also negative pressure in logical food sucking pipe 201, atmospheric pressure pushes grain to pour in into food sucking pipe 201, and the arrangement of food sucking pipe 201 is by driving Cabin side, driver enrich degree by grain in observation food sucking pipe 201 and judge whether there are also grains for the position, if should The position of mobile grain collecting vehicle；Since the communicating passage of separation bin 202 and grain storehouse 402 is sealing structure, when separation bin 202 Isobaric in sealing space when interior formation negative pressure, the grain in grain storehouse 402 will not be back in separation bin 202, so that inhaling The air pressure of grain is acted on completely in food sucking pipe 201, is improved and is inhaled grain ability.

Four, grain is received: after grain enters separation bin 202 by food sucking pipe 201, since air pressure is close in separation bin 202, grain Food pressure reduces suddenly, and grain is fallen in 202 bottom of separation bin by gravity, and grain is pushed to storage by screw auger 403 In silo 402；

Five, dedusting: after grain is promoted separation bin 202 by air, suction ventilator 204 arranges air to multistage dedusting mechanism 5, Air successively passes through every sub- chamber 501, and by the guide functions of the guide disc 601 in the sub- chamber 501 of correspondence, air turns to each height On the dust absorption net 502 of chamber 501, the dust particle in air is corresponded to dust absorption net 502 and is adsorbed, to realize abundant air filtering excessively Purpose.
