Detailed description of the invention
The embodiment of the reciprocal wind riddle of portable convolution in the utility model: as shown in Figure 1 to Figure 3, form primarily of whirl screen sub-agencies, pneumatic separation device 10, walking mechanism and buffer unit, produce circumnutation by plane cyclotron mechanism and reach sieve nest, thus raw grain is evenly scattered rapidly on compass screen surface, sieve nest moving line is transitioned into second half section reciprocating motion gradually from the circumnutation of first half section.To make in raw grain grain and other organic assorted, size is assorted etc. carries out classification and be separated, then the raw grain after classification being separated carries out pneumatic separation device 10 by wind circulating system, to be cleared up into for the purpose of clean grain by raw grain high efficiency screening.Have treating capacity large, dynamic consumption is little, and complete machine smooth running, environmental protection, efficient, noise is low and the feature such as easy maintenance.
Whirl screen sub-agencies comprise frame and on the drive unit, the sieve nest that assemble from front to back, its mid frame by the base 1 be assemblied in walking mechanism and on formed by the floating shelf 3 of damping device 2 float support, damping device 2 has four and is distributed on the corner location place between floating shelf 3 and base 1; The head of sieve nest 4 forward, afterbody arranges backwards, and the head of sieve nest 4 is in transmission connection on drive unit 5 by eccentric block, the afterbody of sieve nest 4 by guiding mechanism along the longitudinal direction guiding movement be assemblied on floating shelf 3, the guide rail that guiding mechanism is extended by the front and back that floating shelf 3 is arranged and the aft mounted slide block of sieve nest 4 are formed, and slide block and guide rail lead along the longitudinal direction and coordinate; Drive unit 5 is on floating shelf 3, drive unit 5 comprises the drive motors be fixed on floating shelf 3, drive motors connects eccentric block by belt transmission, namely the input of eccentric block is connected on the output of drive motors by belt wheel transmission, and the output of eccentric block rotates the head being assemblied in sieve nest 4.Because sieve nest 4 second half section arranges sliding support, sieve nest 4 to gradually become elliptic motion from head, gradually becomes straight reciprocating motion again under the drive of drive unit 5 to the movement locus of afterbody from circular motion, after making sieve, classification grain and each impurity discharge the outer speed quickening of sieve nest 4, improve the treating capacity of screening.
Sieve nest 4 is by the feed hopper 6 of screen box and setting thereof, top cover, sieve plate, large assorted discharging opening 8, little assorted discharging opening 7 and grain discharging opening 9 form, wherein sieve plate is divided into three layers from top to bottom, and interval is arranged, each layer sieve plate is all by the bracket be fixed on screen box, be fixed on the screen cloth on bracket and be connected to the self-cleaning ball composition on screen cloth, and the screen cloth of intermediate layer sieve plate is divided into two sections, first half section is the braiding network segment, be beneficial to raw grain screening efficiency, second half section is the stamped sieve network segment, the insertion sieve aperture that takeoffs to be unfavorable for gently mixing in raw grain enters down one compass screen surface and cannot remove, self-cleaning ball can beat compass screen surface by bullet when sieve nest 4 moves, prevent the impurity blocking screen mesh in raw grain.Linking part between sieve plate and sieve plate and screen box, top cover joining place have rational sealing device, prevent flushing, ensure screening precision.
Pneumatic separation device 10 is fixed on base 1 in the position at sieve nest 4 rear, the inlet communication of pneumatic separation device 10 has clean grain discharging channel 11, the mouth down that goes out of clean grain discharging channel 11 is arranged, the inlet communication of pneumatic separation device 10 is in the upside of discharging channel, and the grain discharging opening 9 of sieve nest 4 is communicated with in the import of discharging channel.Through the raw grain of screening again through the selection by winnowing of cycle winnowing device, by raw grain shoulder to shoulder, light assorted, dust carries out removings collection, improves the screening cleaning effect of raw grain.
Buffer unit comprises the hanger be fixed on floating shelf 3, hanger is in immediately below eccentric block, hanger is made up of the base plate 13 between two polyurethane sheets 12 vertically arranged and bridge joint are fixed on bottom two polyurethane sheets 12, base plate 13 is fixed be bolted to stack fixing balancing weight 14.This buffer unit, for offsetting exciting force to sieve nest 4 impact in the lateral direction, reduces the vibrations of frame, ensures complete machine even running.
Walking mechanism comprises the wheel 15 be arranged on below base 1, wheel 15 has four and is distributed on the corner location place below base 1, the below of base 1 is also provided with the lifting landing leg 16 be vertically elevated, lifting landing leg 16 also has four, four lifting landing legs 16 are arranged in four damping device 2 positions, after shrinking, wheel 15 lands lifting landing leg 16, walks on the ground by wheel 15 to make frame; After lifting landing leg 16 stretches out and puts in place, wheel 15 is maked somebody a mere figurehead by lifting landing leg 16, to ensure that frame is after moving into place, is placed on the station of workshop reliably, places use to be made complete machine by walking mechanism arbitrarily on ground, reservoir area.
In the present embodiment, the operation principle of screening plant is: raw grain enters into upper strata compass screen surface by the feed hopper 6 of sieve nest 4 after buffering shunting, under the effect of whirl screen sub-agencies, raw grain circles round on compass screen surface, back and forth move to sieve nest 4 discharge end, in the process of material screen, every layer of impurity being greater than mesh size can be stayed on compass screen surface, flow out through impurity outlet, the raw grain and the impurity that are less than mesh size enter lower one deck compass screen surface continuation screening, final grain and mixing shoulder to shoulder, little light mixing enters cycle winnowing device selection by winnowing, be less than the little thin assorted of grain grain to be discharged outside sieve nest 4 by collection funnel under compass screen surface.Through cycle winnowing device, fine impurities, dust are collected and discharged, discharging raw grain by cycle winnowing device is exactly clean grain.Finally reach the object of raw grain screening cleaning.
As shown in Figure 4, raw grain at each compass screen surface running orbit is: in raw grain screening process, and the running orbit of raw grain is constantly change, and raw grain enters on the compass screen surface sieve nest 4 from feed hopper 6 and completes from discharging opening discharge to final sizing selection by winnowing, can be divided into four-stage:
Stage one: the material fed concentrated by feed hopper 6, can rapidly and equably raw grain cloth on compass screen surface is opened under the effect of the approximate circular motion of entrance point compass screen surface motion, and automatic classification;
In the stage two: when raw grain flow forward is to sieve nest 4 stage casing, compass screen surface movement locus becomes oval gradually, because raw grain is being uniformly distributed on last stage, now can sieve raw grain fully;
Stage three: substantially complete in the screening of sieve nest 4 end raw grain, compass screen surface movement locus gradually becomes straight reciprocating motion and is beneficial to impurity of grain on compass screen surface and discharges rapidly outside machine.
In other embodiments, frame also can adopt fixed frame, and now frame is fixed on assigned address in factory building.In addition, the sliding support mechanism between sieve nest and frame also can select sliding sleeve and the cooperation of slide bar sleeve, linear guide rail device etc.
