Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples

As shown in fig. 1-2, the anti-blocking and blanking device for screening concrete gravel comprises a bottom frame 1, wherein a vibration box 2 with a vibration motor is arranged on the bottom frame 1, the bottom of the vibration box 2 is connected with the bottom frame 1 through a shock absorption column 21, a filter plate 22 with a high middle part and two low sides is arranged at the inner bottom of the vibration box 2, and filter screens 23 are arranged on two sides of the filter plate 22; a material receiving box 24 is arranged below the vibrating box 2, movable plates 25 matched with the filter sieve 23 are symmetrically arranged in the material receiving box 24, one end of each movable plate 25 is rotatably connected with the material receiving box 24 through a rotating shaft, anti-blocking bristles 26 are arranged on one side, facing the filter sieve 23, of each movable plate 25, and the movable plates 25 are rotated through a driving device to dredge the filter sieve 23.

The other end of the movable plate 25 is provided with an impact block 27 which is matched and impacted with the filter plate 22.

The chassis 1 is further provided with a limiting frame 11, the limiting frame 11 surrounds the periphery of the vibration box 2, and the inner wall of the limiting frame 11 is provided with a protective ring 12.

The driving device comprises a driving motor 3, the driving motor 3 is installed on the bottom frame, an output shaft of the driving motor 3 is provided with a driving wheel, one end of a rotating shaft penetrates out of a material receiving box 24 to be connected with a driven wheel, and the driving wheel and the driven wheel are connected through a synchronous belt 31. The rotation directions of the two driving motors 3 are the same, so that the rotation directions of the two movable plates are the same when the two movable plates work simultaneously.

The top of the material receiving box 24 can be also provided with a shock absorption pad, so that the vibration of the vibration box 2 is prevented from influencing the material receiving box 24, and the stability of the material receiving box 24 is ensured.

The working principle is as follows: when the vibrating screen works, the vibrating box 2 is driven by the vibrating motor to vibrate and sieve, and the sandstone aggregate is sieved and discharged through the filter sieves 23 which are obliquely distributed on two sides; driving motor 3 passes through hold-in range 31 and drives the pivot and rotate, thereby it revolves the axle head and rotates to drive fly leaf 25, rotate to preventing in stifled brush hair 26 inserts the sieve mesh of filter sieve 23 when fly leaf 25, clear up filter sieve 23, get rid of the concrete material that blocks up, and simultaneously, the bump 27 collides on filter 22, further make filter 22 shake, can vibrate the concrete that blocks up in the filter sieve 23 better, get rid of, thereby realize the mediation function of vibrating bin 2, when fly leaf 25 antiport extremely keeps away from filter sieve 23, filter sieve 23 normally sieves the unloading, need not to shut down and clear up.
