[0029] Specifically, the conveying mechanism 5 includes a mounting frame 501 installed on one end of the transmission base 1, a transmission groove 502 is opened on the top of the mounting frame 501, a first conveyor belt 503 is installed on the inner wall of the transmission groove 502, a second conveyor belt 504 is installed on the inner wall of the transmission base 1, and the outer wall of the first backing plate 210 is connected with the inner wall of the second conveyor belt 504. The inner wall of the transmission groove 502 is provided with a second backing plate 505, and the outer wall of the second backing plate 505 is connected with the inner wall of the first conveyor belt 503, two reinforcing frames 506 are fixedly arranged on both sides of the bottom of the mounting frame 501, and one end of each of the two reinforcing frames 506 is fixedly connected with one side of the outer wall of the transmission base 1. A control panel is installed on one side of the transmission base 1, and the first motor 3, the second motor 4, the first conveyor belt 503 and the second conveyor belt 504 are electrically connected with the external power supply through the control panel.

[0030] When working, the coal is placed in the transmission groove 502 on the mounting frame 501 first, and then transmitted to the inclined surface on one side of the top of the transmission base 1 through the first conveying belt 503, and then conveyed in advance through the second conveying belt 504. The mined coal is conveyed through the conveying mechanism 5. During the conveying process, the coal slides off the inclined area on the top of the transmission base 1, and is carried by the coal along the leaf plate of the guide roller 204, and then falls from the other side of the guide roller 204. During this process, the sticky coal is scattered and falls on the inclined plate 202. During this process, part of the coal falls into the guide chute 203 along the gap between the connecting groove 201 and the guide roller 204, and the bottom of the guide chute 203 is inclined, so that the coal scattered into it is guided from one end of the guide chute 203 to one end of the transmission base 1 and falls on the second conveying belt 504 along with the coal on the inclined plate 202. With the transmission of the second conveying belt 504, the coal passes under the two rotating rollers 205 and rotates along with the connecting frame 206 and the rack 207 under the rotation of the rotating rollers 205, so that the coal is scattered again on the second conveying belt 504, so that the coal is scattered again during conveying, without the need for later staff to scatter it. The coal can be dried more when it is dried later, improving the quality of the coal.

[0031] It should be noted that the driving directions of the first motor 3 and the second motor 4 are opposite, the first motor 3 drives the guide roller 204 to rotate towards the second conveying belt 504, the rotating direction of the rotating roller 205 is opposite to that of the guide roller 204, and the second rotating roller 205 rotates synchronously through the meshing of the sprocket 208 and the chain 209. The mounting frame 501 is reinforced by the reinforcing frame 506, so that it can be more stable when conveying coal, and the first and second baffle plates 210 and 505 are installed on the inner walls of the first and second conveying belts 503 and 504 to support the coal more stably.

[0032] The dust falling mechanism 6 includes a water tank 601 fixed on the transmission base 1, a push plate 604 connected with the inside of the water tank 601 through a spring, a water inlet pipe 602 fixedly installed on one side of the water tank 601 and connected with the inside and provided with a one-way valve, a water outlet pipe 603 fixedly installed at the bottom of the water tank 601 and provided with a one-way valve, a first electromagnet 605 fixedly installed at the bottom of the push plate 604, a fixed rod 606 fixedly sleeved with the output end of the second motor 4, and a second electromagnet 607 fixedly installed at one end of the fixed rod 606. A rubber sealing ring 608 is fixedly installed on the side wall of the push plate 604.

[0033] Specifically, the water outlet pipe 603 is provided with a guide mechanism 7, and the guide mechanism 7 includes a filter screen 701 fixedly installed in the water outlet pipe 603, and two symmetrical guide plates 702 fixedly installed at the bottom of the filter screen 701, and the guide plates 702 are arc-shaped.

[0034] When the second motor 4 rotates the connecting frame 206 and the rack 207 (not high speed, but uniform and slow rotation), the fixed rod 606 and the second electromagnet 607 will rotate, at this time the second electromagnet 607 and the first electromagnet 605 are powered and attract each other when they are close to each other. When the second electromagnet 607 rotates to the lower side of the first electromagnet 605, it will attract the first electromagnet 605 to move downward together with the push plate 604, the sealing ring 608 and the spring, thereby pressing the water in the water tank 601 to make the water enter the water outlet pipe 603. Since the second electromagnet 607 is in a rotating state, it will separate from the first electromagnet 605 after a while, and the push plate 604, the sealing ring 608 and the first electromagnet 605 will reset under the action of the spring, so only a small amount of water will be squeezed out for spraying. At the same time, a water level sensor is installed in the water tank 601 to replenish the water in time when the water in the water tank 601 is insufficient.

[0035] When the water enters the water outlet pipe 603, it will be scattered by the filter screen 701 and guided to the surrounding area under the action of the arc-shaped guide plate 702. The filter screen 701 plays a role in scattering water to avoid direct spraying, so that it is sprayed in the form of water mist. At the same time, the arc-shaped guide plate 702 guides the water to the surrounding area to compensate for the gap between the two water outlet pipes 603, thereby achieving more efficient dust reduction.

[0036] Working principle, when conveying coal, first place the coal in the transmission groove 502 on the mounting frame 501 and transmit it to the inclined surface on one side of the top of the transmission base 1 through the first conveyor belt 503, and then transmit it in advance through the second conveyor belt 504. The coal mined is transmitted by the conveying mechanism 5. During the transmission process, the coal slides down from the inclined area on the top of the transmission base 1, and is carried by the coal along the leaf plate of the guide roller 204, and then falls from the other side of the guide roller 204. During this process, the sticky coal is scattered and falls on the inclined plate 202. During this process, part of the coal will fall into the guide chute 203 along the gap between the connecting groove 201 and the guide roller 204, and the bottom of the guide chute 203 is inclined, so that the scattered coal falling into it will be guided from one end of the guide chute 203 to one end of the transmission base 1 and fall on the second conveyor belt 504 together with the coal on the inclined plate 202. With the transmission of the second conveyor belt 504, the coal passes under the two rotating rollers 205 and rotates together with the connecting frame 206 and the rack 207 under the rotation of the rotating rollers 205, thereby scattering the coal again on the second conveyor belt 504.

[0037] When the second motor 4 rotates the connecting frame 206 and the rack 207 through the rotating stick, the fixed rod 606 and the second electromagnet 607 will rotate, at this time, the second electromagnet 607 and the first electromagnet 605 are electrified, and when they are close to each other, they will attract each other. When the second electromagnet 607 rotates to the lower side of the first electromagnet 605, it will attract the first electromagnet 605 to move downward together with the push plate 604, the sealing ring 608 and the spring, thereby extruding the water in the water tank 601, so that the water enters the water outlet pipe 603. When the water enters the water outlet pipe 603, it will be scattered by the filter screen 701 and guided to the surrounding under the action of the arc-shaped guide plate 702. The filter screen 701 plays a role in scattering water, avoiding direct spraying, so that it is sprayed in the form of water mist.
