In order to be convenient for the complete machine debugging and the energy saving, an oscillating motor is adopted to drive; a screening body assembly is supported by a three point framework and three rubber springs; a rubber sleeve is directly pressed and injected out of the torsion spring axle of an electric motor supporting base assembly to form a rubber torsion spring, and one end of the rubber torsion spring is fastened by the upper body of the supporting base and the lower body of the supporting base; the other end of the rubber torsion spring is connected with the screening body by an opening supporting base; the screening body assembly omits a discharge tank and a feed tank.

Description

Single vibratory cleaning sieve that drives

The utility model belongs to the cleaning classifying equipoment of grain processing industry, is a kind of vibratory cleaning sieve by the grain grading particularly.

At present both at home and abroad advanced vibratory cleaning sieve is that the vibrating motor by two same models directly is fixed on the position of centre of gravity of sieve nest assembly both sides, and two motor rotation directions drive the vibratory sieve linear reciprocating motion on the contrary to realize functional requirement.Because two motors of this kind vibratory sieve are installed on the position of centre of gravity of sieve nest assembly both sides, when adjusting sieve nest assembly motion state, require the overlapping angle of eccentric weight at two vibrating motor two ends consistent relatively, two vibrating motor axis are consistent relatively to the angle of inclination of compass screen surface, the anti-phase running of two motors, two vibrating motors must be interlocked when two vibrating motor control circuits of design, to guarantee their synchronous rotations, stop synchronously, otherwise major accident will take place.The torsion axis of existing vibrating motor support assembly adopts interference fit, is pressed in the shock-absorbing sleeve, and this shock-absorbing sleeve is made up of inside and outside metallic sheath therebetween one rubber sleeve, and torsion axis and shock-absorbing sleeve have been formed the rubber torsion spring jointly and be pressed in the whole bearing.This assembly technology complexity easily causes waste product, the manufacturing cost height, and in use rubber sleeve easily separates with metallic sheath and loses the transmitting torque function.Existing vibratory sieve sieve nest is supported on the machine shelf by four higher hollow rubber shock-absorbing springs of internal resistance, is in course of adjustment and need adjusts two shock-absorbing springs of nearly grain end simultaneously, to reach the purpose of adjusting sieve nest assembly angle of inclination.If two shock-absorbing spring Height Adjustment disunities of a side then can make the sieve nest disequilibrium influence equipment operation.On the existing vibratory sieve sieve nest assembly the bigger material feeding box of volume, feed box are housed, have increased equipment volume and weight, cause the motor rotation load big, power consumption is high, many shortcomings such as equipment manufacturing cost height.

The purpose of this utility model is to provide a kind of novel single vibratory cleaning sieve that drives, to overcome the deficiency of existing cleaning vibratory sieve, make its reduce equipment investment, convenient debugging, energy-conservation, reduce all many-sides such as accident rate and obviously improve.

The utility model is to realize like this, a motor that drives the vibratory sieve motion is installed on the electric machine stand assembly of sieve nest bottom of the end of putting out cereal, its electric machine stand assembly is made up of bearing upper body, bearing lower body, rubber torsion spring, opening bearing, the rubber torsion spring adopts the outer directly pressure injection rubber sleeve of torsion axis, bolted is embraced and used to bearing upper body, bearing lower body to rubber sleeve one end that adds of rubber torsion spring, the other end of rubber torsion spring is installed on the opening bearing, and it is connected with the sieve nest assembly with U-bolts.The sieve nest assembly of this utility model is supported by three higher rubber springs of internal resistance on 3 supports, and far going into the grain end is two support springs, and closely going into the grain end is a support spring, and this vibratory sieve has also saved material feeding box and feed box, has alleviated the complete machine load.

The utility model is compared with existing cleaning vibratory sieve, owing to reduced by a motor, made things convenient for debugging, increased the electric equipment safety in utilization, reduced inside and outside metallic sheath on the rubber torsion spring of electric machine stand assembly, and change whole bearing into bearing upper body and bearing lower body, and after being embraced the rubber torsion spring, it uses bolted, so just can often safeguard fastening.Thereby changed former rubber sleeve and separated the disadvantage of losing transmission torque function owing to using fatigue to produce with metallic sheath.Be supported for three rubber springs and support owing to change four rubber springs, so only usefulness is gone into the grain end once supporting the angle of inclination of a tunable integer sieve nest assembly, and supported at three point has more the capable advantage stably of received shipment.This vibratory sieve has saved into and out of hopper, has reduced equipment investment, for production marketing and use have brought many convenience.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1, Fig. 2 drive master, the side schematic diagram of vibratory cleaning sieve for the utility model list, this vibratory cleaning sieve is driven by a vibrating motor 3, for ease of sieve nest assembly 1 angle of inclination debugging and stable, take to add on the Three-point machine frame 5 three rubber springs 6 and support sieve nest assembly 1, closely go into one at grain end, far go into two at grain end.Electric machine stand assembly 2 is as Fig. 3, Fig. 4, shown in Figure 5, by bearing upper body 15, bearing lower body 13, opening bearing 16 with go out the rubber torsion spring that torsion axis 18, rubber sleeve 17 manufacture jointly and form, rubber torsion spring direct pressure injection rubber sleeve 17 outside torsion axis 18 constitutes, bearing upper body 15, bearing lower body 13 embraced an end of rubber sleeve 17 and fastening with bolt 21, the other end of rubber torsion spring is installed on the opening bearing 16, fastening with bolt 22, with U-bolts 14 it is connected with sieve nest transverse axis 19.Vibrating motor 3 usefulness bolts 20 are installed on the bearing lower body 13.Sieve nest assembly 1 is done linear reciprocating motion under vibrating motor 3 drives, grain is entered the upper strata sieve plate 8 at certain angle of inclination through buffering Bulk Grain plate 9 by grain-entering mouth 10, the grain that conforms with certain particle size is through the screen cloth lower floor's sieve plate 7 that bleeds, bigger bigger material matter is discharged from bigger material material outlet 12, bleed the grain of lower floor's sieve plate 7 after lower screen is handled, the little miscellaneous material littler than clean grain granularity spills from lower screen meat, discharge by little foreign material material mouth 4, clean material then flows out from clean grain mouth 11, thereby has reached the purpose by grain granularity screening grain.
