Description

Technical Field

[0001] The invention relates to the technical field of coal transportation, in particular to a coal transportation device with a coal dust suppression function. Background Art

[0002] Coal is mainly mined for use as fuel. At normal temperature and pressure on the surface, accumulated plant remains are transformed into peat or sap through peatification or sapropelization. After being buried, the peat or sap is buried deep underground due to the subsidence of the basin base and is transformed into lignite. Coal has huge applications in various industries. With the development of industry, the demand for coal mining is also increasing. Therefore, the conveying device used in the coal mining process is indispensable. The coal conveying device can significantly improve the coal transportation efficiency.

[0003] A Chinese patent (publication number: CN116374540A) discloses a coal conveying device for a mine. The application arranges side rollers on an adjusting frame, and the adjusting frame is arranged on a deviation correction frame in a hinged manner. In terms of the driving structure, a three-link structure is used to drive the adjusting frame to flip. In order to improve the flipping efficiency, the application arranges an arc track on the deviation correction frame, which can quantitatively set the flipping angle and swing efficiency according to the trajectory of the arc track. Through the two arc tracks, namely the circular and variable diameter arc tracks, and respectively provide uniform speed and accelerated swing structures

[0004] During the transportation process of existing coal conveying equipment, smaller particles or fine powder of coal will generate dust due to the movement of mechanical parts in the conveyor. The conveying device does not have the function of suppressing coal dust, resulting in a large amount of dust. This not only causes a waste of resources, but also causes great pollution to the environment. Summary of the invention

At the same time, the rotation of the driving wheel 1304 can drive the second connecting shaft 1411 to rotate in a circular motion. The driving wheel 1304 can drive the slide plate 1409 to move back and forth longitudinally through the traction plate 1412 by using the transmission member composed of the second connecting shaft 1411, the traction plate 1412 and the first connecting shaft 1410. During the movement, the slide plate 1409 can squeeze the spiral slideway 1407 on the rotating drum 1403 through the squeezing rod 1414 to realize the rotation of the rotating drum 1403, which is beneficial for the filter cone 1404 to throw out the water in the water-containing coal particles under the centrifugal force, thereby improving the utilization rate of water resources.

[0045] Working principle of the present invention:

[0046] When coal is poured into the hopper 4, the coal passing through the hopper 4 can fall onto the conveyor belt 2 in the conveying body 1 and be transported away, and the dust formed by the coal will float out of the hopper 4. At this time, start the water pump 9 so that the water pump 9 can suck water from the water tank 8 through the suction pipe 10, and then transport the water to the atomizing pipe 7 through the first water pipe 11, so that the atomizing pipe 7 can spray atomized water into the hopper 4. At the same time, start the module guide rail 5, so that the slide seat 6 can drive the atomizing pipe 7 to move back and forth horizontally, which is conducive to the comprehensive spraying of the hopper 4 by the atomizing pipe 7, and can play an effect of suppressing dust.

[0047] When the conveyor belt 2 transports coal, the conveyor belt 2 can drive the driving roller 1303 to rotate through the friction force during movement, so that the driving roller 1303 can drive the driving wheel 1304 to rotate synchronously through the rotating column 1302, and the driven wheel 1312 can drive the reciprocating screw 1310 to rotate through the first rotating shaft 1309 through the pulley transmission composed of the driving wheel 1304, the driven wheel 1312 and the transmission belt 1313. Since the spray pipe 1307 can move horizontally on the fixed rod 1305 through the slider 1306, the moving block 1311 can drive the spray pipe 1307 to move back and forth, and when the water pump 9 is running, water can be delivered to the spray pipe 1307 through the second water pipe 1308, which is beneficial for the spray pipe 1307 to spray and flush the conveyor belt 2 after feeding, thereby cleaning the conveyor belt 2.

[0048] When the driven wheel 1312 drives the reciprocating screw 1310 to rotate through the first rotating shaft 1309, the first rotating shaft 1309 can drive the transmission gear 1314 to rotate synchronously. By utilizing the tooth chain transmission composed of the transmission gear 1314, the driven gear 1316 and the transmission chain 1317, the driven gear 1316 can drive the cleaning roller 1318 to rotate synchronously through the second rotating shaft 1315 during the rotation process, which is beneficial for the cleaning roller 1318 to drive the wiping pad to rotate in the opposite direction of the moving direction of the conveyor belt 2 after feeding, thereby improving the cleaning effect of the wiping pad.

[0049] The water flow for flushing the conveyor belt 2 after feeding can enter the drum 1403 through the downspout 1401 and the sleeve 1402, so that the filter cone 1404 in the drum 1403 can filter and intercept the coal particles in the water flow. The filtered water flow can be returned to the second water pipe 1308 by the return pipe 1406 under the negative pressure of the second water pipe 1308, so that the water flow can be recycled. At the same time, the rotation of the driving wheel 1304 can drive the second connecting wheel 1304 during the rotation process. The connecting shaft 1411 moves in a circular trajectory. The transmission member composed of the second connecting shaft 1411, the traction plate 1412 and the first connecting shaft 1410 can enable the driving wheel 1304 to drive the slide plate 1409 to move longitudinally through the traction plate 1412. During the movement, the slide plate 1409 can squeeze the spiral slideway 1407 on the rotating drum 1403 through the squeezing rod 1414 to realize the rotation of the rotating drum 1403, which is beneficial for the filter cone 1404 to throw out the moisture in the water-containing coal particles under the centrifugal force, thereby facilitating the improvement of the utilization rate of water resources.
