In order to make the impurity in air more fully be contacted with dust absorption net 502, this programme is added in multistage dedusting mechanism 5 Water conservancy diversion frame 6, the extending direction of water conservancy diversion frame 6 is identical as the axial direction of multistage dedusting mechanism 5, on water conservancy diversion frame 6 is uniformly provided with guide disc 601, guide disc 601 is located at the air outlet of corresponding sub- chamber 501, and the edge of guide disc 601 is stuck up to air inlet, works as gas Stream enters first sub- chamber 501 from the air outlet of suction ventilator 204, and gas shock is reversely expanded around later on guide disc 601 It dissipates, air-flow is impacted first on the inner wall close to air inlet side, and then the inner wall along the sub- chamber 501 flows to air outlet, herein In the process, the impurity in air-flow is adsorbed by dust absorption net 502, and the air-flow being discharged in first sub- chamber 501 enters second sub- chamber 501 In, and so on, until last sub- chamber 501 more fully cleans air-flow.With the progress of filtering, the sub- chamber of rear side 501 dedusting pressure is gradually reduced, therefore the size that will be far from the sub- chamber 501 of suction ventilator 204 reduces one by one, unnecessary to save Materials'use, mitigate weight of equipment.

Since dust absorption net 502 is mounted on using dismountable mode in sub- chamber 501, when needing cleaning, directly extraction carries out Flushing, since dust absorption net 502 uses metal wire material or plastic wire, metal wire material or plastic wire are more existing to the adhesiveness of dust There is filter cotton material adhesiveness common in technology to reduce very much, using very easy removing dust particle when high pressure water washing.

When selecting air draught acc power, since power P needed for suction ventilator (KW) calculation formula is：

P=1.1 × Qp/ (3600 × 1020 η) (2)

In formula (2), Q is air quantity；P is the full blast pressure of suction ventilator；η is air draught engine efficiency, generally takes 0.75~0.85, this example In take 0.8；Power P then uses most common 15KW in this field, and it is 40058181 to bring formula (2) into and can obtain Qp；Grain strand will be taken off When the rotary speed ω of dragon is set as 60r/min, takes off grain auger and take off grain 19m per hour³, inventor measures, the wind of cleaner Amount Q is receive flow vector 50 times or so, i.e. 950m³/ h, therefore show that full blast pressure p is 4.2KPa；

P=ρ gh (3)

In formula (3)：ρ is the averag density of drying wheat, generally 750kg/m³, g is gravity coefficient, takes 9.8N/kg；It will It is 5.6m that full blast pressure zone, which enters (3) formula to obtain the height h that wheat is picked up, it is known that the suction ventilator of 15KW disclosure satisfy that daily production needs It wants.

A kind of operating method of grain collecting vehicle, this approach includes the following steps：

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

Two, hold together grain：It takes off grain auger 305 for two to rotate, in the frame for holding together shell 301 and prismatic sub-material frame 309 and surrounding 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, grain is inhaled：No.1 motor 205 drives suction ventilator 204 to form negative pressure in separation bin 202, is connected with separation bin 202 Also it is negative pressure in logical food sucking pipe 201, atmospheric pressure pushes grain to be poured in into food sucking pipe 201, and the arrangement of food sucking pipe 201 is by driving Cabin side, driver judge whether the position also has grain by observing the substantial degree of grain in food sucking pipe 201, 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 by gravity in 202 bottom of separation bin, 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 passes through every sub- chamber 501 successively, and by the guide functions of the guide disc 601 in the sub- chamber of correspondence 501, 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.
