Therefore, the control method and circuit connection will not be described in detail.

[0035] Working principle:

[0036] When the dust collecting equipment of the mineral screening machine is actually used, the control panel is used to make the two groups of reduction motors 16 work, and at the same time, the output ends of the two groups of forward and reverse motors 10 are synchronously rotated clockwise through the synchronous controller. The output ends of the two groups of forward and reverse motors 10 can synchronously drive the two groups of winding disks 11 to rotate, and the left group of winding disks 11 is used for winding, and the right group of winding disks 11 is used for unwinding. At the same time, the dust hopper 3 moves to the left, and the control panel is used to make the output ends of the two groups of forward and reverse motors 10 rotate counterclockwise synchronously through the synchronous controller, and the left group of winding disks 11 is used for unwinding, and the right group of winding disks 11 is used for winding. Working, at the same time, the dust hopper 3 moves to the right. In this process, the output ends of the two groups of reduction motors 16 drive the gear 17 to rotate. Since the two groups of gears 17 are meshed with the two groups of outer gear rings 15, the rotating two groups of gears 17 can push the two groups of outer gear rings 15 to rotate, and the rotating two groups of outer gear rings 15 can respectively drive the two groups of shaft tubes 14 to rotate. The rotating two groups of shaft tubes 14 can scrape off the dust particles adsorbed on the surfaces of the two groups of pull ropes 12 through the two groups of scrapers 18. The installation plate 9 and the installation box 13 are provided to prevent dust particles from hindering the movement of the dust hopper 3, thereby improving the practicality of the dust collecting equipment of the mineral screening machine. At the same time, According to the above operation, the dust hopper 3 can move left and right along the two sets of cross bars 2. At the same time, the control panel is used to make the two sets of fans 8 work. The two sets of fans 8 can make the two sets of integrated chambers in a negative pressure state. Dust particles and air can enter the interior of the two sets of dust collecting chambers 7 through the dust hopper 3, the connecting hose 4 and the three-way pipe 5. The dust particles can be retained by the two sets of filter bags 23, and the air can be discharged through the two sets of fans 8. When it is necessary to clean the dust particles inside the two sets of filter bags 23, the control panel is used to extend a set of electric telescopic rods 24 and stop a set of fans 8 on the same side. When a set of blocking blocks 25 on the same side is moved down and inserted into a set of limiting holes on the same side, When the dust collector 21 is inside the plate 22, the operator pulls out the sealing plug 20 on the same side. At this time, the filter bag 23 on the same side can be taken out through the through holes 19 on the same side. The dust particles inside this group of filter bags 23 can be cleaned.
