Description

Blowing & sucking combined cleaning screen

The utility model relates to a kind of blowing and drawing type combined cleaning sift, is mainly used in complete set of rice milling equipment.

At present the combined cleaning sift that is adopted in the complete set of rice milling equipment is because its sieve nest vibrating inertia force is big, and its spare and accessory parts damage easily, the wind that stone remover blows out do not have fixed flow to, cause light assorted flying upward, dust is big, and because size of screen surface is limited by complete set of equipments, its screen route is short, and impurity-eliminating effect is poor.

The purpose of this utility model is to provide a kind of blowing and drawing type combined cleaning sift, and it can make vibrating inertia force be able to balance, prolongs service life of a machine, solves the short problem of its screen route, improves impurity-eliminating effect effectively.

The purpose of this utility model realizes with following technical proposals: it comprises suction formula cleaning sieve and blowing stone-removing machine, and it also comprises frame, double rocker mechanism, eccentric stiffener and motor; The cleaning sieve is positioned at the frame top, and stone remover is positioned at cleaning sieve below, and double rocker mechanism is fixed on the frame, and its rocking bar two ends connect cleaning sieve and stone remover respectively; Motor is fixed on the frame, drive eccentric stiffener and the motion of stone remover blower fan through belt transmission, eccentric stiffener is made up of the big bearing block of eccentric bushing, bearing, connecting rod and the connecting rod that connect firmly with Pulley shaft, the connecting rod two ends are big bearing block of coupler link and stone remover respectively, adopt full-closed structure between cleaning sieve and the stone remover, be provided with selected wind adjustable plate between the big assorted sieve of cleaning sieve and the little assorted sieve, big assorted sieve bottom is provided with little assorted delivery chute.

The utility model is owing to adopt suction formula cleaning sieve and blowing stone-removing machine combination, make wind that stone remover blows out from the bottom to top fixed flow to, dust is not excessive, cleaning sieve and the shared rocking bar of stone remover, make vibrating inertia force be able to balance, vibration reduces, service life of a machine increases, and the while is owing to both combinations, the effect of little assorted sieve overdraught, make classification accelerate, material and impurity are respectively towards two rightabout motions, and is assorted with respect to little, screen route lengthening, thereby it is short to have solved the screen route effectively, the problem of impurity-eliminating effect difference.

Accompanying drawing has provided an embodiment of the present utility model.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model A-A cutaway view.

The utility model is described in further detail with reference to the accompanying drawings.

With reference to Fig. 1, suction formula cleaning sieve 9 is positioned at frame 10 tops, and blowing stone-removing machine 8 is positioned at cleaning sieve 9 belows, and cleaning sieve 9 tops are provided with charging aperture 1, inlet scoop 2, on the inlet scoop 2 blower fan are installed; Set gradually big assorted sieve 4, little assorted sieve 6, little assorted delivery chute 7 in the cleaning sieve 9 from top to bottom, little assorted delivery chute 7 goes out the stone end storage stone cistern is set, big assorted sieve 4, little assorted sieve 6, little assorted delivery chute 7, storage stone cistern all are fixed on cleaning sieve 9 casings, are provided with selected wind adjustable plate 5 between big assorted sieve 4 and little assorted sieve 6; Frame 10 is positioned at cleaning sieve 9 belows, and its top is provided with double rocking lever bearing 29, and motor 13, stone remover blower fan 30, eccentric stiffener 12 all are fixed on the frame 10; With reference to Fig. 2, motor 13 drives belt pulley 28 through belt transmission, drive eccentric stiffener 12 motions, eccentric stiffener 12 is by eccentric bushing 26, the big bearing block 27 of bearing and connecting rod, connecting rod 25 is formed, eccentric bushing 26 is fixed on the Pulley shaft through key, the big bearing block 27 of bearing set and connecting rod on eccentric bushing 26, connecting rod 25 is by bolt, nut constitutes, connecting rod 25 1 ends connect with the big bearing block 27 of connecting rod, the other end connects with connecting rod small bearing bracket 24, on stone remover spiral case side plate 22, connecting rod axis 23 and stone remover axis 21 are housed, connecting rod small bearing bracket 24 is set on the connecting rod on axis 23 bearings, stone remover axis 21 two ends are set in the axis hole of an end of two rocking bars 17, double rocker mechanism 11 is made of rocking bar 17 and rocker bearing 29, axle bed 18 is installed on the rocker bearing 29, fixed pin shaft 19 is set in the axle bed 18, bearing 20 is housed on it, rocking bar 17 is sleeved on the bearing 20, be set with cleaning screen box axis 16 in the other end axis hole of rocking bar 17, cleaning screen box axis 16 is installed on the cleaning sieve box side plate 14,15 is rubber shaft bearing, in the present embodiment, rocking bar 17 is provided with 4, and 2 is 1 group of double rocking lever, is symmetrical in each 1 group of cleaning sieve front and back, same eccentric stiffener 12 also is provided with 2 covers, each cover of front and back.

The utility model course of work is as follows: power by motor 13 through belt pulley 28, eccentric stiffener 12 reaches on the connecting rod 25, axis 23 motions on the drivening rod, through stone remover spiral case side plate 22, stone remover axis 21 drives rocking bar 17 around fixed pin shaft 19 swings, drive 9 vibrations of cleaning sieve through cleaning screen box axis 16, because of stone remover 8 connects with rocking bar 17 two ends respectively with cleaning sieve 9, make both vibrate in the opposite direction, its vibrating inertia force is able to balance, vibration reduces, stone remover 8 adopts with cleaning sieve 9 that bellows is totally-enclosed to be connected, after material enters from charging aperture 1, fall on the big assorted sieve 4, under the effect of the air-flow from the bottom to top that stone remover 8 blower fans and cleaning sieve 9 induced-draught fans are produced, light assorted being pulled away, big assorted be up to big assorted sieve 4 with the sieve nest vibration along sieve plate and go out the stone end and flow out, material and the little assorted sieve aperture of mixing greatly that then passes are fallen on little assorted sieve 6 compass screen surfaces, because material is not bored a hole, material on the little assorted sieve 6 is cumulative, along with the sieve nest vibration is paved with whole compass screen surface gradually, at this moment, because the effect of air-flow, material is half suspended state, follows the material rapid classification, above light material floats over, heavier impurity then sinks on the compass screen surface, under sieve nest vibration effect, little mixing separated along passing sieve aperture gradually in the up process of compass screen surface, flows into little assorted delivery chute 7, the impurity that can not sieve thoroughly then is up to selected end, flow out selected back, and the then following bed of material of lighter upper materials is that sliding surface is descending, flows into stone remover 8, according to different materials, can regulate selected wind air quantity by regulating selected wind adjustable plate 5.
