DETAILED DESCRIPTION
[0031] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
[0032] Example 1
[0033] A dust-proof coal mine conveyor, such as Figure 1 and Figure 2 As shown, it includes a conveyor body 1, a shock-absorbing and wetting mechanism 2 and a spraying mechanism 3. The upper part of the conveyor body 1 is V-shaped. The left part of the conveyor body 1 is provided with a shock-absorbing and wetting mechanism 2, which can cushion the coal falling downward and reduce the dust generated by the height difference of the coal. The right part of the conveyor body 1 is provided with a spraying mechanism 3, which can reduce the dust of coal transportation.
[0034] like Figure 1 and Figure 3 As shown, the shock-absorbing and wetting mechanism 2 includes a nozzle 21, an elastic band 22 and a water pipe 23. Three elastic bands 22 are connected to the upper left part of the conveyor body 1 from left to right in sequence. The elastic band 22 can cushion the fallen coal. There are two water pipes 23, which are respectively installed on the front and rear sides of the left part of the conveyor body 1. The water pipes 23 are connected to the external water supply equipment. There are two nozzles 21, which are respectively connected to the inner side of the upper part of the water pipe 23, and the nozzles 21 are connected to the water pipe 23.
[0035] like Figure 1 and Figure 4 As shown, the spraying mechanism 3 includes a spray pipe 31, a connecting pipe 32, a support frame 36 and an adjusting component. The support frame 36 is welded to the front side of the right part of the conveyor body 1, the spray pipe 31 is installed on the upper part of the support frame 36, the connecting pipe 32 is connected to the front side of the spray pipe 31, the connecting pipe 32 is connected to the spray pipe 31, and the connecting pipe 32 is connected to the external water supply equipment. An adjusting component is provided on the upper part of the support frame 36, and the adjusting component can adjust the spraying range of the spray pipe 31.
[0036] like Figure 4As shown, the adjustment component includes a first motor 33, a bidirectional screw rod 34 and a sleeve 35. The first motor 33 is bolted to the upper part of the support frame 36. The first motor 33 is located above the spray pipe 31. The bidirectional screw rod 34 is connected to the output shaft of the first motor 33 through a coupling. Two sleeves 35 are threadedly connected to the bidirectional screw rod 34. The two sleeves 35 are symmetrically arranged on the front and back sides. The sleeves 35 are both sleeved on the spray pipe 31. The sleeves 35 can move inwards and outwards to adjust the spraying range of the spray pipe 31.
[0037] When people need to transport coal, they can use the dust-proof coal conveyor for transportation. First, place the dust-proof coal conveyor under the coal mine exit, and the elastic belt 22 is located directly under the coal mine exit. Then turn on the conveyor body 1 and the external water supply equipment. At this time, the water source will flow into the nozzle 21 through the water pipe 23, and then the nozzle 21 will spray water inward. Then, when the coal falls from the exit and passes through the elastic belt 22, the elastic belt 22 will buffer the coal, which can reduce the coal mine caused by the height difference. The impact force of falling downwards can reduce the generation of dust, and when the coal passes between the two nozzles 21, the water sprayed by the nozzle 21 will wet the coal, avoiding the generation of a large amount of dust in the later coal transportation process. After that, when the coal falls onto the conveyor body 1, the conveyor body 1 will transport the coal. At the same time, when the external water supply equipment is turned on, the water source will flow into the spray pipe 31 through the connecting pipe 32, and then sprayed out from the spray pipe 31 in atomization, so that water mist can be sprayed on the upper part of the conveyor body 1 to prevent the transported coal from being polluted. The dust prevention treatment of the coal mine is carried out to reduce the dust generated during the transportation of the coal mine. When people transport a small amount of coal mine, due to the small amount of coal mine, a large amount of dust will not be generated during the transportation of the coal mine. At this time, the range of spraying water mist by the spray pipe 31 can be reduced. First, the first motor 33 is turned on, and then the output shaft of the first motor 33 drives the bidirectional screw rod 34 to rotate clockwise, thereby driving the sliding sleeve 35 to move inward. The movement of the sliding sleeve 35 inward can reduce the spraying range of the spray pipe 31 and reduce the amount of water sprayed. When a large amount of coal mine needs to be transported, the output shaft of the first motor 33 is controlled to drive the bidirectional screw rod 34 to rotate counterclockwise, and then drive the sliding sleeve 35 to move outward. The movement of the sliding sleeve 35 outward can expand the spraying range of the spray pipe 31. In this way, the spraying range of the spray pipe 31 can be adjusted to save water resources. When the coal mine is transported, the conveyor body 1 and the external water supply equipment can be closed. Repeat the above operation to reduce the dust of the coal mine during the transportation of the coal mine and carry out dust prevention treatment on the coal mine.
[0038] Example 2
[0039] On the basis of Example 1, Figure 1 , Figure 5 and Figure 6As shown, it also includes a rotating mechanism 4, which includes a second motor 41, a fixed frame 42, a cotton board 43, a rotating rod 44 and a telescopic plate 45. The fixed frame 42 is fixedly connected to the left side of the conveyor body 1, and the second motor 41 is connected to the middle of the upper part of the fixed frame 42 in a through-type manner. The rotating rod 44 is connected to the output shaft of the second motor 41 through a coupling. There are two cotton boards 43, and the two cotton boards 43 are respectively connected to the front and rear sides of the rotating rod 44. The cotton boards 43 can further buffer the coal falling downward. The lower part of the cotton boards 43 is slidably connected with the telescopic plate 45, and the first spring 46 is connected between the inner side of the left and right parts of the telescopic plate 45 and the inner wall of the cotton board 43.
[0040] When the coal passes through the elastic band 22 and falls onto the conveyor body 1, the rotating mechanism 4 can be used for operation. When the coal passes through the elastic band 22 and falls downward onto the cotton board 43, the cotton board 43 will buffer the coal. Then, the second motor 41 is turned on, so that the output shaft of the second motor 41 drives the rotating rod 44 to rotate, and then drives the cotton board 43 and the telescopic plate 45 to rotate. At this time, the coal on the cotton board 43 and the telescopic plate 45 will slide down along the inclined surface of the upper part of the conveyor body 1, so that the coal can be further buffered. When the telescopic plate 45 rotates to the lower part of the conveyor body 1, under the squeezing of the lower part of the conveyor body 1, the telescopic plate 45 will move inward, and the first spring 46 will be compressed. When the telescopic plate 45 turns away from the lower part of the conveyor body 1, under the action of the first spring 46, the telescopic plate 45 moves outward. When the coal is transported, the second motor 41 can be turned off. In summary, the coal can slide down along the inclined surface of the upper part of the conveyor body 1, further buffering the coal, so that the dust prevention effect is better.
[0041] like Figure 1 and Figure 7 As shown, it also includes a dispersing mechanism 5, which includes a connecting frame 51, a dispersing frame 52, a second spring 53 and a rotating rod 54. The rotating rod 54 is connected to the upper left side of the second motor 41. The connecting frame 51 is fixed to the upper left side of the conveyor body 1. The dispersing frame 52 is slidably connected to the connecting frame 51. The second spring 53 is connected between the front and rear sides of the dispersing frame 52 and the inner wall of the connecting frame 51.
[0042] When the coal needs to be scattered during the transportation process, the scattering mechanism 5 can be used for operation. When the output shaft of the second motor 41 rotates, the output shaft of the second motor 41 will also drive the rotating rod 54 to rotate, so that the rotating rod 54 intermittently moves the scattering frame 52. With the cooperation of the second spring 53, the scattering frame 52 will move back and forth repeatedly, and then the second spring 53 will undergo adaptive deformation, so that the coal falling downward can be scattered. When the coal is transported, the second motor 41 is turned off, and the rotating rod 54 will also stop rotating and no longer move the scattering frame 52. In summary, the coal can be scattered to prevent large pieces of coal from falling downward and to prevent uneven wetting of the coal.
[0043] like Figure 1 and Figure 8 As shown, a cleaning mechanism 6 is also included, which includes a scraper 61 and a guide rod 62. The guide rod 62 is welded to the upper rear side of the conveyor body 1, and the scraper 61 is movably connected to the guide rod 62. The scraper 61 is in contact with the upper side of the conveyor body 1.
[0044] After the coal is transported, a lot of coal ash will remain on the conveyor body 1. In order not to affect the conveyor body 1 in the later conveying of the next batch of coal, the cleaning mechanism 6 can be used to operate and move the scraper 61 to the right so that the scraper 61 scrapes the coal ash on the conveyor body 1 to the right. In this way, the coal ash on the conveyor body 1 can be scraped off to avoid generating a large amount of dust when transporting the next batch of coal. After the coal ash on the conveyor body 1 is scraped off, the scraper 61 is moved to the left and reset. When people need to transport the coal, the scraper 61 is rotated backward so that the scraper 61 is away from the conveyor body 1. When the coal is transported, people can rotate the scraper 61 forward and reset it to scrape off the coal ash on the conveyor body 1. In summary, the coal ash remaining on the conveyor body 1 can be cleaned to avoid being affected when transporting the next batch of coal and improve the transportation effect.
[0045] like Figure 1 and Fig. 9 As shown, it also includes a filter plate 7 for absorbing dust in the air. The scraper 61 is connected with the filter plate 7, and the filter plate 7 is made of activated carbon.
[0046] When the scraper 61 moves left and right, the scraper 61 will also drive the filter plate 7 to move left and right. Since the filter plate 7 is made of activated carbon, the filter plate 7 will also absorb the dust in the air during the movement, thereby reducing the dust in the air and avoiding affecting the health of surrounding workers.
[0047] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
