Preferably, the trigger 203 includes a top plate 203a disposed on top of the first base 202a, a second spring 203b is further disposed on top of the top plate 203a, the top plate 203a is slidably matched with the frame 201, a movable contact 203a-1 is further disposed at one end of the top plate 203a, and a stationary contact 203c is further disposed below the movable contact 203 a-1. The second spring 203b is a compression spring having an elastic coefficient smaller than that of the first spring 202 g. Normally, the top plate 203a is lifted by the filter 202f on the first base 202a, so that the movable contact 203a-1 and the stationary contact 203c are separated normally.

The motor 203d is a servo motor, and forward and reverse rotation can be realized through a control module. When the movable contact 203a-1 contacts the stationary contact 203c, the motor 203d is started to drive the driving gear 203e to rotate, that is, when the dust adhered to the filter screen 202f is more, the weight of the filter screen 202f is heavier, so that the top plate 203a falls, and when the driving gear 203e rotates, the first base 202a and the second base 202b move upwards and downwards due to the meshing of the driving gear 203e with the two long racks 202 d.
Preferably, the rapping member 204 comprises a driven gear 204a disposed between two short racks 202e, the driven gear 204a has a hollow shaft end and a third spring 204b is disposed therein. When the first base 202a and the second base 202b move up and down, they are not driven at the beginning, and when the saw teeth on the short rack 202e contact the driven gear 204a, they drive the driven gear 204a to rotate.
Preferably, the rapping member 204 further includes a cam shaft 204c disposed inside the rotation shaft of the driven gear 204a and fixedly connected to the third spring 204b, and the cam shaft 204c is further provided with a cam 204d and a coil spring 204e, respectively. The third spring 204b is a tension spring, and the cam shaft 204c can move a certain distance in the axial direction of the driven gear 204 a. When the driven gear 204a rotates, the cam shaft 204c is driven to rotate, and the coil spring 204e also contracts to store energy. The side of the cam shaft 204c has a large chamfer.
Further, the rapping member 204 further comprises a rapping rod 204f arranged at both sides of the cam 204d, wherein the rapping rod 204f is slidably engaged with the frame 201, and one end of the rapping rod 204f is engageable with the cam 204d, and the other end is engageable with the surface of the filter screen 202 f. The side of the end of the rapping bar 204f near the cam 204d is also provided with a chamfer. The rapping bar 204f may be moved horizontally and laterally.
Further, a fourth spring 204i is further sleeved on the rapping rod 204f, one end of the fourth spring 204i is fixed with the rapping rod 204f, the other end of the fourth spring is fixed with the frame 201, and extrusion blocks 204g are further respectively arranged at the bottoms of the first base 202a and the second base 202b, which are close to the bottoms of one side of the rapping rod 204 f. The fourth spring 204i is an extension spring, mainly used for resetting the rapping bar 204 f. When the first base 202a and the second base 202b are displaced, the first base 202a is up, the second base 202b is down, the second base 202b is up, when the first base 202a is down, the driven gear 204a is meshed with the short rack 202e, the coil spring 204e is enabled to store energy, then when the driven gear 204a reaches a place where the driven gear 204a does not have saw teeth, the coil spring 204e releases energy, the cam 204d is enabled to rotate rapidly, when the cam 204d rotates, the cam 204d intermittently impacts the rapping rod 204f, and the other end of the rapping rod 204f continuously impacts the filter screen 202f, so that the filter screen 202f is further cleaned.
The working principle of the device is as follows: the dust collection cabin 101 is arranged at the input end position of the coal conveying belt, then the negative pressure machine 103 is started, and dust floating on the belt conveyor is sucked away through the dust collection channel 102. To prevent the pipe from being blocked, a filter screen 202f is provided to filter the dust, and the dust with larger particles is filtered. As a result of the long-term use, the filter screen 202f is inevitably stuck with dust, thereby causing clogging of the filter holes. For this reason, when the filter screen 202f is adhered to a certain extent by dust, the weight of the filter screen 202f will reach a certain value, and break through the elastic force of the first spring 202g, so that the filter screen 202f on the first base 202a moves downward, at this time, the top plate 203a on the top of the filter screen will lose the barrier, the movable contact 203a-1 contacts the stationary contact 203c under the action of the second spring 203b, the circuit is conducted, the motor 203d is started, and the driving gear 203e drives the first base 202a and the second base 202b to start moving through the long rack 202 d. Dust adhered to the surface of the filter 202f on the first base 202a is cleaned by the scraping bar 202h, and the filter 202f on the second base 202b is cleaned by the first base 202 a.
In addition, when the first base 202a and the second base 202b move, the short rack 202e on the other side drives the driven gear 204a to rotate, and drives the cam shaft 204c to store energy for the coil spring 204e. It should be noted that, at this time, the cam 204d and the rapping bar 204f are not in a plane, because the rapping bar 204f is prevented from rapping the filter screen 202f during the movement of the first base 202a and the second base 202b, and the movement is prevented from interfering. Therefore, when the second base 202b moves up, the pressing block 204g at the bottom thereof presses the cam 204d to move axially, so that the cam 204d and the rapping bar 204f become the same plane. At the same time, the driven gear 204a just reaches the place where the end of the short rack 202e is not provided with saw teeth, the driven gear 204a is out of the block, the coil spring 204e starts to release energy, the cam 204d is driven to rotate, the cam 204d intermittently impacts the rapping rod 204f, and the other end of the rapping rod 204f continuously impacts the filter screen 202f, so that the filter screen 202f is further cleaned.
It should be noted that the above embodiments are only for illustrating the technical solution of the present application and not for limiting the same, and although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present application may be modified or substituted without departing from the spirit and scope of the technical solution of the present application, which is intended to be covered in the scope of the claims of the present application.
