Install moving mechanism on mounting bracket 6, moving mechanism is connected with dust fall mechanism, moving mechanism includes two racks 10, two racks 10 respectively with two dust fall subassembly in connecting plate 12 fixed connection, and two racks 10 all cooperate with gear 9 meshing, gear 9 is located between two racks 10, gear 9 fixed mounting is on two 8 output shafts of motor, two 8 fixed mounting of motor are on mounting bracket 6, fixed mounting has diaphragm 11 on the rack 10, diaphragm 11 and the 7 sliding fit of guide way on the mounting bracket 6.

Two long boards 20 have been arranged along the long limit direction symmetrical of mounting bracket 6, and long board 20 fixed mounting is in the below of mounting bracket 6, is the linearity on the long limit direction of long board 20 and is provided with a plurality of bosss 21, boss 21 and push rod 16 sliding fit, and push rod 16 has four, and four push rods 16 respectively with four siphunculus 14 fixed connection.

The working principle is as follows: when the coal is conveyed, the first motor 4 is started, the output shaft of the first motor 4 drives the transmission roller 2 to rotate on the belt frame 1, the transmission roller 2 is rotated to drive the belt 3 to rotate, then the coal to be conveyed is poured on the belt 3, and the coal is conveyed through the rotation of the belt 3.

In the coal conveying process, a water pump in a water tank 19 is started, water in the water tank 19 is pumped into a water delivery pipe 18 through the water pump, then the water enters a water distribution pipe 17 through the water delivery pipe 18, the water respectively flows into a through pipe 14 connected with the water distribution pipe 17 through the water distribution pipe 17, the water then flows into a sprinkler head 15 below the through pipe 14 through the through pipe 14 and is sprayed out of a water outlet hole 23 formed in the sprinkler head 15, the diameter of the water outlet hole 23 is small, the water coming out of the water outlet hole 23 is small water drops, and the small water drops are combined with dust on coal and fall down, so that the dust in the air is reduced.

When the water pump in the water tank 19 is started, the second motor 8 is started, the output shaft of the second motor 8 drives the gear 9 to rotate, the racks 10 which are positioned on two sides of the gear 9 and meshed and matched with the gear 9 are stirred by the gear 9, the transverse plate 11 fixedly connected above the racks 10 slides on the guide groove 7, namely the two racks 10 respectively enable the two connecting plates 12 to move towards one side close to the gear 9, the transverse plate 11 and the guide groove 7 are used for guiding, the gear 9 close to the connecting plates 12 drives the balls 13 which form ball pairs with two ends of the connecting plates 12 to close to the gear 9, and the balls 13 and the through pipe 14 move together. At this time, the push rod 16 fixedly installed on the through pipe 14 continuously slides through the boss 21 on the long plate 20, when the push rod 16 slides through the highest point of the boss 21, the push rod 16 pushes the through pipe 14, so that the through pipe 14 drives the ball 13 to rotate on the connecting plate 12, that is, the central axis of the through pipe 14 is no longer perpendicular to the ground, when the push rod 16 leaves the boss 21, the central axis of the through pipe 14 is again perpendicular to the ground, and the purpose of doing so is to make the angle of the sprinkler head 15 perform reciprocating adjustment, so that small water droplets can be sprayed onto air and coal at different angles, thereby enabling the small water droplets to be more thoroughly combined with dust, and improving the dust settling effect. It should be noted that both the water diversion pipe 17 and the water supply pipe 18 are flexible and elastic, so that the water diversion pipe 17 is not damaged when the through pipe 14 deflects, and the water supply pipe 18 is not broken by the movement of the water diversion pipe 17 when the connection plate 12 carries the water diversion pipe 17 to move.

When the two connecting plates 12 move to the vicinity of the gear 9, the motor two 8 is rotated reversely, so that the two connecting plates 12 are gradually far away from the gear 9, the two connecting plates 12 move in a reciprocating manner, the dust falling effect is improved, the surface of the dust absorption pad 22 mounted on the dust cover 5 is rough, and the purpose of adsorbing more dust is achieved. The dust pad 22 may be adhered to the surface of the dust cover 5, and when the surface of the dust pad 22 is full of dust, the dust pad 22 is removed and replaced with a new dust pad 22.
