[0034] Furthermore, the elastic screening mechanism 3 includes a sieve plate 31, a sleeve 32, a telescopic rod 33, a fixed plate 34 and a first compression spring 35. The sieve plate 31 is slidably and interlacedly connected with the inner cavity of the upper hopper 1, and multiple sleeves 32 are respectively fixedly connected to the corners of the inner wall of the upper hopper 1. The fixed plate 34 is located inside the sleeve 32, and the top of the telescopic rod 33 is fixedly connected to the fixed plate 34. The other end of the telescopic rod 33 is fixedly connected to the sieve plate 31.

The dust collection box 51 and the bottom end of the adjustment plate 551 are both provided with ventilation grooves. The second compression spring 555 is always in a compressed state, so that a stable downward elastic force can be applied to the positioning rod 554 through the slide plate 553. When the ventilation groove of the adjustment plate 551 is connected with the ventilation groove opened in the dust collection box 51, the gas sucked in by the fan 52 will be discharged directly. When the positioning rod 554 is inserted with another positioning hole, the adjustment plate 551 blocks the ventilation groove, so that the gas sucked in by the fan 52 flows to the cleaning mechanism 6.

[0041] Method of use of the present invention:

[0042] When the device is used to feed rubber particles, the motor 41 is started. The motor 41 can drive the transmission rod 42 to rotate, and can also drive the rotating rod 43 to rotate through the synchronization component 47, so that the crushing rod 44 can break up the agglomerated materials intercepted by the fixed rod 45. At the same time, the inclined screen plate 31 can be intermittently squeezed by the squeezing plate 46, so that the screen plate 31 can reciprocate in the vertical direction under the elastic force of the first compression spring 35, so that the incoming rubber particles can be screened and the agglomerated materials can be broken up at the same time.

[0043] The transmission rod 42 can drive the fan 52 to rotate synchronously when rotating, so as to absorb the dust generated when the rubber particles are screened and crushed inside, and then pass through the filter 54 to be discharged through the ventilation slot;

Then, by rotating the screw 61, the sliding block 63 drives the nozzle head 64 to slide horizontally along the limit rod 62, so that the multiple high-pressure nozzles on the nozzle head 64 can spray and clean each sieve hole on the sieve plate 31, effectively preventing impurities, dust or rubber particles from clogging the sieve holes and affecting the normal use of the sieve plate 31.
