Description

Technical Field

[0001] The utility model relates to the technical field of coal mine production, in particular to a coal mine conveying device. Background Art

[0002] The mined coal needs to be transported with the help of a conveying device. The main function of the conveying device is to transfer the mined coal to another storage point. This conveying device, which we generally call a coal mine belt conveyor, plays an important role in various links such as coal mining, production, transportation and processing. Coal mine belt conveyors can not only play a role in the production and processing of coal, but can also be used in the production of other minerals. However, when we use belt conveyors to transport coal, it is easy to cause coal dust pollution due to the flying of a large amount of coal powder and dust. To solve this problem, we can inject an appropriate amount of water or water mist into the coal on the belt through a nozzle. This dust reduction method is easy to operate and has outstanding effects, and is widely used.

[0003] At present, coal mine belt conveyors can timely carry out dust reduction treatment by spraying water, but it is inevitable that there will be a lot of water-coal residue on the belt. As the water-coal residue remaining on the belt surface accumulates for a long time, it will affect the normal use of the coal mine belt conveyor. At the coal transportation site, we also actually saw staff manually cleaning with mops, and sometimes they had to stop the machine, which was also inefficient. In addition, a large amount of coal needs to be transported every day, which will consume a lot of manpower costs. Therefore, we proposed a coal mine conveying device to deal with this problem. Summary of the invention

[0004] The utility model aims to solve the problem that the coal mine belt conveyor in the prior art does not have the function of cleaning the water-coal residue remaining on the belt surface while reducing dust, and has to be cleaned manually, which has high labor cost and low efficiency, and thus proposes a coal mine conveying device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A coal mine conveying device comprises a frame and an active roller and a driven roller arranged on the frame, a belt is connected between the active roller and the driven roller, and a water spraying mechanism is arranged above the belt; it also comprises a cleaning mechanism located below the belt, the cleaning mechanism comprises a scraper, the scraper is connected to a driving mechanism, and a brush abutting against the belt is installed on the top of the scraper.

[0007] In some embodiments, the water spray mechanism includes two columns respectively located on both sides above the frame, a water spray pipe is connected between the two columns, a nozzle is connected to the bottom of the water spray pipe, and a plurality of nozzles are arranged, and the nozzles are evenly distributed along the width direction of the belt; one end of the water spray pipe is closed, and the other end of the water spray pipe passes through one of the columns and is connected to a water supply pipe.

[0008] In some embodiments, a base is provided below the scraper, the base is a hollow structure, the cross section of the scraper is an inverted T-shape, the vertical portion of the scraper passes through the side wall of the base, the horizontal portion of the scraper is located inside the base, and a spring is provided between the horizontal portion of the scraper and the side wall of the base. By providing the spring, the brush is always in contact with the belt.

[0009] In some embodiments, the top surface of the base is a sloped surface or a double sloped surface, so as to facilitate the discharge of the water-coal residue swept away by the brush to both sides.

[0010] In some embodiments, a motor is mounted on the frame, a reducer is connected to the output end of the motor, a rotating shaft is connected to the output end of the reducer, the rotating shaft is rotatably arranged on the frame, and the rotating shaft and the active roller are connected via a transmission mechanism.

[0011] In some embodiments, the transmission mechanism includes sprocket 1 and sprocket 2, a chain is connected between sprocket 1 and sprocket 2, sprocket 1 is installed on the rotating shaft, and sprocket 2 is installed at one end of the active roller.

[0012] In some embodiments, the driving mechanism includes a disc mounted on a rotating shaft and a connecting rod eccentrically arranged on the disc, one end of the connecting rod is hinged to the disc, and the other end of the connecting rod is hinged to the base. When the disc rotates, the connecting rod pulls the base to reciprocate left and right.

[0013] In some embodiments, two guide rods are horizontally arranged on the frame, and the base is sleeved on the guide rods. The two guide rods are respectively located on both sides of the spring, and the guide rods provide a guiding function for the base.

[0014] The utility model is provided with a transmission mechanism, a water spraying mechanism, and a cleaning mechanism. The motor drives sprocket one in the transmission mechanism to rotate through a reducer. The sprocket one drives sprocket two and an active roller to rotate through a chain, thereby driving the driven roller and the belt to operate, thereby realizing the transportation of coal. In the process of transporting the coal, water in the water spraying mechanism is sprayed from a nozzle to the belt to reduce dust on the coal. At the same time, the sprocket one drives the disc to rotate through the rotating shaft. When the disc rotates, the base is pulled to reciprocate left and right through the connecting rod. The base drives the brush to reciprocate left and right through the scraper. In this way, when the belt moves, the brush will clean the water-coal residue on the surface of the belt. Therefore, in the dust reduction process, the utility model also has the function of cleaning the water-coal residue remaining on the surface of the belt.

[0015] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model realizes the transportation of coal, and at the same time cleans the water and coal residues on the surface of the belt during the dust reduction process through the brush that reciprocates left and right, so as to improve the cleaning effect of the belt.
