Description

Technical Field

[0001] This application relates to the field of coal mining and transportation, and more specifically, to a coal transportation device for coal mining. Background Technology

[0002] Coal mining is the process of extracting and utilizing underground coal seams. During mining, coal and stone are transported using belt conveyors. Typically, coal and stone are collected in hoppers and then flow onto the belt conveyor, where they are collected again. However, controlling the material output during transport is difficult, and the uneven distribution of coal and stone on the belt can easily lead to localized accumulation. Furthermore, in complex coal mine environments, such as underground mining areas and the final transport point outside the mine entrance, where there are elevation differences, belt conveyors alone are insufficient for transporting coal and stone. Coal and stone can easily slip off the belt during transport or accumulate on the belt. Additionally, accurately measuring the weight of coal and stone transported each time is impossible, hindering safety supervision and subsequent storage in the coal mine. Therefore, belt conveyors have significant shortcomings. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a coal transfer device for coal mining, which can control the flow rate of coal and stone discharge, can cope with complex coal mine faces through reciprocating coal mine cars, and can count the weight of coal and stone transferred each time, which is beneficial to the safety monitoring and subsequent storage of coal mines.

[0023] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] like Figures 1-6 As shown, a coal transfer device for coal mining according to an embodiment of this application includes:

[0025] The belt conveyor assembly 100 includes a drive roller 110, a driven roller 120, a tensioner 130, a conveyor belt 140, mounting grooves 150, and buffer idlers 160. The drive roller 110 and the driven roller 120 are respectively sleeved on both sides of the conveyor belt 140, so that the conveyor belt 140 forms an elliptical structure. The tensioner 130 is fixedly connected to both sides of the driven roller 120. The mounting grooves 150 are evenly arranged on the conveyor belt 140, and the buffer idlers 160 are arranged between the conveyor belts 140.

[0026] The coal conveying assembly 200 includes a feeding hopper 210, a feeding cylinder 220, a material control element 230, a storage bin 240, and a weighing element 250. The feeding cylinder 220 is fixedly connected to the feeding hopper 210, the material control element 230 is fixedly connected inside the feeding cylinder 220, the feeding cylinder 220 is fixedly connected above the storage bin 240, the storage bin 240 is fixedly connected to the weighing element 250, and the weighing element 250 is fixedly connected to the mounting column 150. It should be noted that the weighing element 250 can reflect the weight of the coal in the storage bin 240 in real time and transmit the weight to the statistical computer in real time, thereby enabling real-time statistics of the weight of the transferred coal and strengthening the safety management and storage management of coal. During coal transportation, coal from underground is fed into the feed cylinder 220 through the feed funnel 210, and then into the storage bin 240. Simultaneously, the flow rate of coal into the storage bin 240 is controlled by the material control component 230 to prevent coal accumulation. The weighing component 250 provides real-time feedback on the weight of the coal in the storage bin 240, enabling real-time statistical collection of the transported coal weight for convenient safety and storage management. During transport, the drive roller 110 is activated, driving the conveyor belt 140, which in turn rotates the driven roller 120. The buffer rollers 160 balance the transport. When transporting coal, the downward pressure on the conveyor belt 140 enables the storage bin 240 to reciprocate on the conveyor belt 140. This allows the coal to be transferred smoothly even in complex coal seam environments, preventing coal from falling or accumulating during transfer, thus avoiding issues that could affect coal transport efficiency. This solves the problem of coal falling and accumulating during transfer in complex coal seam environments in existing technologies, and avoids the problem of not being able to count the real-time weight of coal during transfer, which is detrimental to safety and storage management in coal mines.

[0027] like Figure 3 As shown, the drive roller 110 includes a drive motor 111, a drive roller 112, and a support frame 113. The drive roller 112 is fixedly connected to the output end of the drive motor 111, the drive motor 111 is fixedly connected to one support frame 113, and the drive roller 112 is rotatably connected to another support frame 113. Starting the drive motor 111 drives the drive roller 112 to rotate, thereby causing the conveyor belt 140 and the driven roller 120 to rotate.

[0028] Furthermore, the tensioning component 130 includes a mounting support column 131, a hydraulic rod 132, a connecting block 133, and an auxiliary support frame 134. The mounting support column 131 supports the ground, the hydraulic rod 132 is fixedly connected to the end of the mounting support column 131, the connecting block 133 is fixedly connected to the telescopic end of the hydraulic rod 132, and the connecting block 133 is fixedly connected to both ends of the driven roller 120. The connecting block 133 has a sliding groove 135, and the end of the auxiliary support frame 134 is slidably connected to the sliding groove 135. After the conveyor belt 140 has undergone long-term reciprocating transport, the conveyor belt 140 may become loose. To avoid this phenomenon, the hydraulic rod 132 is activated to drive the connecting block 133 to slide, thereby increasing the distance between the driven roller 120 and the driving roller 112, thus re-tensioning the conveyor belt 140 and avoiding affecting the transmission efficiency of the conveyor belt 140.

[0029] like Figure 4 As shown, the buffer idler component 160 includes a buffer support frame 161 and idlers 162. The idlers 162 are sequentially installed on the buffer support frame 161 and are located below the conveyor belt 140. As coal continuously enters the storage bin 240, the downward pressure on the conveyor belt 140 increases. To prevent excessive downward pressure on the conveyor belt 140 from damaging it and affecting transmission, idlers 162 are evenly distributed below the conveyor belt 140 to provide a certain supporting force, thereby offsetting the downward pressure on the conveyor belt 140 and preventing damage to the conveyor belt 140.

[0030] like Figure 5 As shown, the material control component 230 includes a material control mounting frame 231, a rotating motor 232, a rotating column 233, a material control plate 234, and a feeding plate 235. The material control mounting frame 231 is fixedly connected to the feeding funnel 210, the rotating motor 232 is fixedly connected to the material control mounting frame 231, the rotating column 233 is fixedly connected to the output end of the rotating motor 232, the material control plate 234 is fixedly connected to the end of the rotating column 233, and the feeding plate 235 is fixedly connected to the feeding cylinder 220. The feeding plate 235 is located at the lower end of the material control plate 234, and the material control plate 234 and the feeding plate 235 are provided with feeding ports 236. By starting the rotating motor 232 to drive the rotating column 233 to rotate, the rotation of the control plate 234 is controlled. When the overlap between the control plate 234 and the feed inlet 236 on the feed plate 235 is high, the flow rate of coal and stone falling is faster. Thus, by controlling the overlap between the control plate 234 and the feed inlet 236 on the feed plate 235, the flow rate of coal and stone falling is controlled.

[0031] like Figure 6As shown, the storage bin 240 includes a bin body 241 and a storage support column 242, which is fixedly connected to the bin body 241. The storage support column 242 is used to balance and support the bin body 241. The bottom of the bin body 241 is a downwardly sloping surface, and a discharge hatch 243 is opened on the side of the end of the downwardly sloping surface. An electric hatch 244 is hinged to the discharge hatch 243. The design of the downwardly sloping surface allows the coal falling into the bin body 241 to automatically concentrate at the lower end of the downwardly sloping surface, thereby facilitating unloading and preventing coal from accumulating in the intermediate bin.

[0032] Furthermore, the weighing component 250 includes a weighing plate 251, a weighing sensor 252, and a weighing mounting bracket 253. The weighing plate 251 is fixedly connected to the bottom of the storage bin 240. The weighing sensor 252 is installed on the lower side of the corners around the weighing plate 251. The weighing mounting bracket 253 is fixedly connected below the weighing sensor 252 and is bolted to the mounting column 150. By preset, the weighing sensor 252 is set to zero. When coal enters the bin 241, the bin 241 presses down, thereby subjecting the weighing sensor 252 to a greater downward pressure, thus facilitating the recording of the weight of the coal.

[0033] In summary, the working principle of a coal transfer device for coal mining according to this utility model embodiment is as follows: During coal transportation, underground coal is fed into the feed cylinder 220 through the feed funnel 210, and then into the storage bin 240. Simultaneously, by controlling the overlap of the feed inlets 236 on the control plate 234 and the feed plate 235, the flow rate of coal entering the storage bin 240 is controlled, thus preventing coal accumulation. Furthermore, when coal enters the bin 241, the bin 241 is pressed down, causing the weighing sensor 252 to experience increased downward pressure, facilitating the recording of the coal weight. This allows for real-time statistical collection of the transferred coal weight, facilitating safe coal management and storage. During transfer, the drive roller 110 is activated, driving the conveyor belt 140, which in turn rotates the driven roller 120. As coal continuously enters the storage bin 240, the conveyor belt 140 experiences increased pressure. As the downward pressure increases, to prevent excessive downward pressure on the conveyor belt 140 from damaging it and affecting transmission, evenly spaced idler rollers 162 are installed below the conveyor belt 140. This provides the conveyor belt 140 with a certain supporting force, thus counteracting the downward pressure. This allows the conveyor belt 140 to support the box 241 and enables the box 241 to reciprocate on the conveyor belt 140. This allows coal to be transferred smoothly even in complex coal seam environments, preventing coal from falling or accumulating during transfer, which would affect coal transport efficiency. This solves the problem of coal falling and accumulating during transfer in complex coal seam environments in existing technologies, and avoids the problem of not being able to accurately measure the real-time weight of coal during transfer, which is detrimental to safety and storage management in coal mines.
