Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mine conveyor, in particular to a coal mining transportation device. BACKGROUND

[0002] The coal mining transportation device is a core transportation equipment for the comprehensive mechanized coal mining face in the coal mine. Its main task is to continuously, efficiently and automatically transport the coal cut by the coal mining machine from the working face to the next level of roadway belt conveyor until the coal is transported to the ground.

[0003] In order to adapt to different transportation links and distances, the conveying device usually has multiple and continuous conveyors. When the coal mine is transported, the coal is evenly laid on the conveying belt and transported by the transmission of the conveying belt. When the coal is transported to the next conveyor node, the two conveyors are close, and the inertia generated by the conveying belt makes the coal temporarily suspended, thereby completing the transfer of the coal mine.

[0004] Although the above conveying device can better complete the transportation of the coal mine, in actual use, after the coal is mined, it can be simply broken and transported into the conveyor. When the mined coal has low coalification degree, loose texture and high volatile matter, more powdery substances are easily generated during the breaking or transporting process. Due to the humid characteristics of the coal mine environment, the coal powder is easily adhered to the surface of the normal coal. When the subsequent coal enters the spraying dust removal conveying area, a large amount of spraying liquid contacts the surface of the coal, causing more powdery substances on the surface of the normal coal to form stubborn sludge and adhere to the conveying belt, which is difficult to clean and reduces the service life of the conveyor.

[0012] Preferably, the guide blocks are arranged in an arc shape, and the bottom of the reciprocating rod is arranged in an arc shape.

[0013] Preferably, a roller is rotatably connected to the top of the reciprocating rod, and the roller is in contact with the guide bottom plate.

[0014] Preferably, a plurality of convex strips are fixedly connected to the outer surface of the driving roller, and the plurality of convex strips are all made of flexible rubber material.

[0015] Preferably, the discharging mechanism further comprises an auxiliary assembly, the auxiliary assembly comprises at least two mounting frames, each mounting frame is fixedly connected to the top of the heating plate, and a plurality of push plates are fixedly connected to the bottom of each mounting frame.

[0016] Preferably, the actuating plate is configured as an arc shape, with one side of the arc facing the higher side of the inclined surface of the heating plate.

[0017] Compared with the prior art, the present invention provides a coal mine transportation device, which has the following beneficial effects:

[0018] 1. By setting up a discharge mechanism, the material is pre-loaded with dust on the coal mine surface before entering the dust suppression spraying area, thanks to the cooperation of the heating plate and collection holes. This effectively avoids the problem of forming stubborn coal sludge during spraying due to excessive coal dust generated when conveying coal with low coalification. This overcomes the shortcomings of the prior art, reduces the difficulty of cleaning the conveyor belt in the spraying area, and improves the service life of the conveyor.

[0019] 2. This invention, through the configuration of the drive components, with the cooperation of the guide block and the reciprocating rod, drives the guide plate and the heating plate to swing up and down reciprocally. This up-and-down swing enhances the effect of the coal material jumping on the surface of the heating plate, thus making it easier to shake off the coal dust from the coal surface. At the same time, the jumping causes vibration between the coal and the heating plate, which can accelerate the falling speed of coal powder in the collection hole and prevent coal powder from getting stuck in the collection hole. It also drives the guide plate to jump, thereby accelerating the speed at which the guide plate guides the coal powder, improving the cleaning effect on the coal surface and the efficiency of coal powder collection.

[0020] 3. By setting up auxiliary components, the top of the coal mine will contact the actuating plate when there is a large coal mine. Under the pushing and guiding of the actuating plate, the larger coal mine can be rolled irregularly, so that the top or side of the larger coal mine is close to the heating plate. This avoids affecting the drying effect of coal powder that is far away due to excessive height, and improves the uniformity of drying. Attached Figure Description

[0032] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, some features described in the examples may be combined in other examples.

[0033] like Figures 1 to 6 As shown, this embodiment provides a coal mine transportation device, including a support frame 100. A first conveyor body 101 and a second conveyor body 102 are fixedly installed on the top of the support frame 100. The height of the first conveyor body 101 is greater than that of the second conveyor body 102. A discharge mechanism 200 is provided between the first conveyor body 101 and the second conveyor body 102 for removing damp, sticky dust adhering to the surface of the coal mine.

[0034] The discharge mechanism 200 includes two mounting plates 201, which are fixedly connected to the first conveyor body 101. A heating plate 202 is rotatably connected between the two mounting plates 201. The heating plate 202 is an electric heating element and is inclined to guide the coal and improve the dryness of the area through which the coal passes. The heating plate 202 is inclined and has multiple collection holes 203. The discharge mechanism 200 includes a drive assembly, which is located on the side of the second conveyor body 102 near the first conveyor body 101. The drive assembly supports the second conveyor body 102 and drives the second conveyor body 102 to reciprocate.

[0035] Furthermore, multiple deceleration rods 204 are fixedly connected to the heating plate 202. The deceleration rods 204 are staggered and evenly arranged with the collection holes 203, which increases the time that coal dust stays in the collection holes 203. At the same time, when the coal rolls down on the heating plate 202, it is blocked by the deceleration rods 204, which increases the amplitude of its jumping and improves the shaking effect.

[0036] Furthermore, a guide plate 205 is fixedly connected to the side of the heating plate 202 near the second conveyor body 102. The guide plate 205 is located at the bottom of the heating plate 202 and is inclined. The guide plate 205 and the heating plate 202 form a V-shape, so that the drive component drives the heating plate 202 and the guide plate 205 to swing back and forth at the same time. This not only improves the flow effect of the material on the heating plate 202, but also improves the sliding and collection speed of coal dust on the guide plate 205.

[0037] Furthermore, multiple streamlined chutes can be provided on the guide base plate 205, so that the collected coal powder slides down to the designated position along the streamlined chutes, avoiding irregular sliding and the coal powder sliding out of the guide base plate 205.

[0038] Furthermore, the deceleration lever 204 is set as a semi-cylindrical shape, with its arc surface away from the heating plate 202. By setting the arc surface, the material can be blocked and jump, while also preventing the material from being blocked too much and getting stuck.

[0039] Furthermore, the drive assembly includes two mounting blocks 211, which are fixedly connected to the side of the second conveyor body 102 near the first conveyor body 101. A rotating shaft 212 is rotatably connected between the two mounting blocks 211. A drive roller 213 is fixedly connected to the outer surface of the rotating shaft 212. The drive roller 213 contacts the conveyor belt of the second conveyor body 102. At least two guide blocks 214 are fixedly connected to the outer surface of the rotating shaft 212. The height of the guide blocks 214 is lower than the height of the drive roller 213. A guide sleeve 215 is fixedly connected to the bottom of the mounting block 211. A reciprocating rod 216 is slidably connected inside the guide sleeve 215. The bottom of the reciprocating rod 216 contacts the rotating shaft 212, and the top of the reciprocating rod 216 contacts the guide base plate 205. When the rotating shaft 212 rotates, the guide base plate 205 is pushed up and down by the cooperation of the guide blocks 214 and the reciprocating rod 216.

[0040] Furthermore, the guide block 214 is set in an arc shape, and the bottom of the reciprocating rod 216 is set in an arc shape to reduce stress during contact and reduce wear.

[0041] Furthermore, a roller 217 is rotatably connected to the top of the reciprocating rod 216. The roller 217 contacts the guide base plate 205, reducing the wear of the reciprocating rod 216 and the guide base plate 205.

[0042] Furthermore, multiple protrusions 218 are fixedly connected to the outer surface of the drive roller 213. All protrusions 218 are made of flexible rubber material to increase the friction between the drive roller 213 and the second conveyor body 102, while not scratching the conveyor belt of the second conveyor body 102, thus ensuring the normal rotation of the drive roller 213.

[0043] Furthermore, the discharge mechanism 200 also includes auxiliary components, which include at least two mounting brackets 221. Each mounting bracket 221 is fixedly connected to the top of the heating plate 202. Several actuating plates 222 are fixedly connected to the bottom of the mounting bracket 221. The actuating plates 222 are arc-shaped, with one side of the arc facing the higher side of the inclined surface of the heating plate 202. Under the pushing and guiding of the actuating plates 222, larger pieces of coal can be made to roll irregularly, thereby bringing the top or side of the larger pieces of coal closer to the heating plate 202, thus avoiding the drying effect on the distant coal powder due to excessive height.

[0044] In a further embodiment, based on the above embodiment, the width of the collection hole 203 can be increased, and a sliding plate and a locking block can be provided inside. The size of the collection hole 203 can be adjusted by sliding the sliding plate inside the collection hole 203, so that different types of coal and the size of the coal powder particles produced can be collected according to the type of coal mine.

[0045] The working principle of all the content in the above embodiments is as follows:

[0046] In the initial state, the heating plate 202 is located between the first conveyor body 101 and the second conveyor body 102, connecting the space between the first conveyor body 101 and the second conveyor body 102. The bottom of the reciprocating rod 216 is in contact with the rotating shaft 212, and the protrusion 218 is in contact with the conveyor belt of the second conveyor body 102.

[0047] The following describes the working principle and beneficial effects of the material feeding mechanism 200:

[0048] When the coal is being transported and transferred, it is conveyed from the first conveyor body 101 to the second conveyor body 102. When the coal enters the second conveyor body 102, it first passes over the upper surface of the heating plate 202. Since the temperature of the top of the heating plate 202 is higher than that of other areas, and because the heating plate 202 is tilted, when the coal rolls from the tilted heating plate 202 onto the second conveyor body 102, the coal is affected by the temperature, which makes the relatively wet coal powder on the outer surface become drier, reducing the adhesion between the coal powder and the lumpy coal. At the same time, during the process of rolling towards the second conveyor body 102, the vibration generated by the rolling can shake off the coal powder on the outer surface of the coal. The shaken coal powder slides along the heating plate 202 towards the second conveyor body 102, and falls into the collection hole 203 when it passes through the collection hole 203, thus completing the removal of coal powder from the outer surface of the coal.

[0049] Furthermore, by setting the deceleration rod 204, the coal powder that can be shaken off the outer surface of the coal mine is retained in the area of ​​the collection hole 203. At the same time, by setting the deceleration rod 204, when the coal mine rolls down on the heating plate 202, it is blocked by the deceleration rod 204, which increases its jumping amplitude and improves the shaking effect. This better shakes off the wet coal powder on the outer surface of the coal mine and improves the coal removal effect.

[0050] Furthermore, by setting the guide plate 205, the coal dust falling from the collection hole 203 falls onto the guide plate 205, and is then guided to the designated position by the inclined guide plate 205, preventing the coal dust from falling everywhere.

[0051] By setting up a discharge mechanism 200, at the coal mine transfer point, before entering the dust suppression spraying area, the amount of dust on the coal mine surface is reduced in advance with the cooperation of the heating plate 202 and the collection hole 203. This effectively avoids the problem of forming stubborn coal sludge during spraying due to the large amount of coal dust generated when conveying coal with low coalification degree. It overcomes the shortcomings of the existing technology, reduces the difficulty of cleaning the conveyor belt in the spraying area, and improves the service life of the conveyor.

[0052] Furthermore, through the configuration of the drive assembly, when the conveyor belt of the second conveyor body 102 is in conveying operation, the friction between the drive roller 213 and the convex strip 218 drives the drive roller 213 to rotate simultaneously, which in turn drives the rotating shaft 212 to rotate simultaneously. When the rotating shaft 212 rotates, the guide block 214 moves closer to the bottom of the reciprocating rod 216, and then pushes the arc surface of the reciprocating rod 216 through the arc surface of the guide block 214, causing the reciprocating rod 216 to slide upward under the guidance of the guide sleeve 215, which in turn pushes the guide bottom plate 205 to move upward. Under the action of the guide bottom plate 205, the heating plate 202 rotates upward, and when the guide block 214 moves away from the bottom of the reciprocating rod 216 with the rotation of the rotating shaft 212, the bottom of the reciprocating rod 216 loses support, and then gravity... The bottom is reset to release the push on the guide plate 205 and the heating plate 202, allowing them to return to their original positions. Then, under the rotation of the rotating shaft 212, and with the cooperation of the guide block 214 and the reciprocating rod 216, the guide plate 205 and the heating plate 202 are driven to swing back and forth. This up-and-down swing enhances the jumping effect of the coal material on the upper surface of the heating plate 202, which is more conducive to shaking off the coal dust from the coal mine surface. At the same time, the jumping causes vibration between the coal mine and the heating plate 202. The resulting vibration can accelerate the falling speed of the coal powder in the collection hole 203, preventing the coal powder from getting stuck in the collection hole 203. It also drives the guide plate 205 to jump, which can accelerate the speed at which the guide plate 205 guides the coal powder, improving the cleaning effect on the coal mine surface and the efficiency of coal powder collection.

[0053] Furthermore, by setting the roller 217, when the guide base plate 205 and the heating plate 202 rotate, a small amount of relative displacement will occur between the guide base plate 205 and the reciprocating rod 216. Thus, the roller 217 can reduce the friction between the reciprocating rod 216 and the bottom of the guide base plate 205, improve the smoothness of pushing and reduce the wear between the two.

[0054] Furthermore, as the coal passes over the upper surface of the heating plate 202, the installation frame 221 and the agitator plate 222 allow the top of larger coal pieces to contact the agitator plate 222. Under the pushing and guiding action of the agitator plate 222, the larger coal pieces can roll irregularly, causing their tops or sides to approach the heating plate 202. This prevents the drying effect on distant coal powder from being affected by excessive height, thus improving the uniformity of drying.

[0055] It should be noted that due to the irregularity of coal particles, some coal particles may roll or shake as they slide from the heating plate 202 toward the second conveyor body 102, while some may remain stationary and slide toward the second conveyor body 102. However, the movement of the coal particles caused by the heating plate 202 can still shake off most of the coal dust.

[0056] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
