Description

The assorted clearly stone unit mahine that goes of raw grain

The utility model belong to be used for sieving with use air-flow with solid from device combination technique field that solid separates.

In grain processing industry, the slubbing operation that raw grains such as paddy, wheat are processed is to remove and to remove sandstone to the foreign material, shrivelled kernel, the dust that mix in the raw grain.Finishing this procedure now is to use main equipment, and is that unit carries out respectively.Because mixing clearly, going has a lot of weak points in the design of stone unit, makes effect very undesirable.The for example flat screen twin shaft transmission of clear assorted screening, vibration is big, sieve angle hour big assorted pacing up and down on compass screen surface in the use, raw grain was again with mixing down greatly when the sieve angle was big; And for example charging aperture is not beaten the awns device, makes the ail awn of wheat sneak into raw grain, is difficult to clean out; The rate of pulverizing that also has raw grain between the charging elevator wheel hub belt causes waste up to 2%, and the grain winnowing pan bore of carrying on the charging elevator is square in addition, and resistance is big, and wearing and tearing are big; More outstanding is that assorted clearly sieve, stone remover and units such as blower fan, charging elevator are dynamic respectively separately, causes energy consumption big.

At the problems referred to above, the purpose of this utility model is to provide a kind of collection to mix, go stone, lifting, selection by winnowing clearly, beat awns all is combined on the frame, and the assorted clearly stone unit mahine that goes of small-sized raw grain of a shared motor, transmission device.Positive effect being arranged, and outstanding substantive distinguishing features and progress are arranged, is the invention on the raw grain processing equipment.

The utility model is finished with following mode: it has frame 1, in that sieve structure and following sieve structure are installed on the frame 1, single shaft four eccentric wheels 19 is housed between the two; Last sieve structure comprise big assorted sieve 2, in assorted sieve 4 double deck screens, one end end have big assorted row mouthfuls 3, in assorted row mouthfuls 5, wherein the compass screen surface of big assorted sieve 2 is zigzag compass screen surfaces 20; Following sieve structure comprises little assorted sieve 6, grey sieve 7 double deck screens, and its sieve bottom is communicated with little assorted ash row mouth 8; In following sieve structure bottom stone remover 9, blower fan 11 are installed, these blower fan 11 air outlets connect air supply duct 16 and discharge blower fan 13 and communicate with raw grain selection by winnowing charging aperture 12, the shrivelled kernel dust that install on frame 1 top; One end of stone remover 9 has stone to arrange mouth 10, and end is clean paddy row mouth 15 in addition; On frame 1 top raw grain selection by winnowing charging aperture 12 is installed, this raw grain selection by winnowing charging aperture 12 communicates with last sieve structure, and be provided with in raw grain selection by winnowing charging aperture 12 and beat awns device 28, this dozen awns device 28 is made of the awns oar 23 of beating of propelling spiral 22 on the main shaft and end; The shrivelled kernel dust also is installed on frame 1 top discharges blower fan 13 and motor 18, transmission device 21, above-mentioned go up sieve structure, down sieve structure, stone remover 9, blower fan 11, raw grain charging elevator 14 and beat awns device 28, selection by winnowing all with above-mentioned motor 18, transmission device 21 shared this power transmission that links; The elevator belt 27 of raw grain charging elevator 14 is needle roller with shank net 26 on the wheel hub 25 and contacts; Feed hopper 17 is housed on this elevator, and putting forward grain winnowing pan 24 oral area shapes is semicircle arcuations.

The utility model has following advantage: collection is mixed, is gone stone, lifting, selection by winnowing clearly, beats awns and all be combined on the frame, and a shared motor, transmission device, and function is complete, and is compact to design, particularly saves energy consumption 40%.This machine 220V electricity widely is used for the rural area.Big assorted sieve compass screen surface indention compass screen surface, the zigzag screen cloth advances under the grain sieve, and propelling is big assorted to discharging opening, and effect is good especially.Single shaft four eccentric gearings, according to difference screening requirement, the amplitude difference, four eccentric throws have nothing in common with each other, and eccentric angle is also inequality, thereby reduces vibration, and balance quality is good.Blower fan air-supply recycles, and power saving, cost are low, and machine volume is little, the charging elevator to put forward grain winnowing pan oral area shape be the semicircle arcuation, have and put forward the advantage that the grain resistance is little, reduce the winnowing pan friction.

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a structural representation of beating awns device 28;

Fig. 3 is wheel hub 25, the shank net 26 of raw grain charging elevator 14, the assembly structure schematic diagram of elevator belt 27;

Fig. 4 is that the A of Fig. 3 is to view.

With reference to Fig. 1-Fig. 2, only 1500 watts of the utility model powers of motor are mixed, are gone stone, lifting, selection by winnowing clearly, beat awns and all be combined on the frame 1 a shared transmission gear for electric motor.Operation principle is as follows: starter motor 18,14 runnings of raw grain charging elevator promote, paddy is carried into feed hopper 17, carrying grain winnowing pan 24 fills with paddy and enters raw grain selection by winnowing charging aperture 12, beat awns device 28 advance spiral 22 by it and beat awns oar 23 with grain and ail enter successively after separately big assorted sieve 2, in assorted sieve 4, little assorted sieve 6, ash sieve 7, ail is discharged blower fan 13 discharges from flat shell dust.At this moment big assorted row mouthfuls 3 discharges big assorted, in assorted row mouthfuls 5 assorted in discharging, little assorted and ash is discharged from little assorted ash row mouthfuls 8.Remove stone by stone remover 9 then, sandstone is arranged mouthful 10 discharges from removing stone, and what obtain in the clean paddy row mouth 15 is finished product paddy.During blower fan 11 runnings, air supply duct 16 is blown into raw grain selection by winnowing charging aperture 12 with wind, and the shrivelled kernel dust is discharged blower fan 13 and discharged shrivelled kernel, dust.The blower fan 11 coaxial supercharging fan blades of setting up.Adopt the air-supply of two air channels, be used for the elevator dedusting.Screening design single shaft four eccentric wheels 19 design four eccentric shafts according to the amplitude that screens different eccentric throws and angle, and screening effect is good, reduces vibration, and balance quality is good; Zigzag compass screen surface 20 advances big assorted the discharge.With reference to Fig. 3, Fig. 4, the elevator belt 27 of raw grain charging elevator 14 is needle roller with the shank net 26 of wheel hub 25 and contacts, and has eliminated the face contact between the belt wheel hub and has pulverized a large amount of paddy, avoids causing waste.
