Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a coal loading and transportation device for coal mining. Background Technology

[0002] A coal mine is an area where humans extract coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are usually dug underground to extract the coal, which is called an underground coal mine. When the coal seam is very close to the surface, the surface soil layer is usually stripped directly to extract the coal, which is called an open-pit coal mine. In the process of coal mining, coal transportation equipment is needed to transport the coal.

[0003] According to a material transport device for coal mining disclosed in patent number CN 223015605 U, the device collects fallen coal material by rotating a stop block to disengage from a ratchet and then rotating a baffle on a side seat to a horizontal position. After transporting, the baffle can be rotated back to a vertical position. This device can collect fallen material during the transport of coal mining materials. However, during coal transport, especially at the drop point, transfer point, and when the belt vibrates, a large amount of dust is generated, which can easily cause loss of the coal material itself, seriously pollute the working environment, and pose a safety hazard of dust explosion. Existing devices lack dust suppression and recovery of coal scattered during transport. Furthermore, in order to monitor and detect the quality of coal during transport in real time, periodic sampling is required. Existing devices lack sampling of coal during transport, resulting in poor practicality. Therefore, we propose a coal loading and transport device for coal mining. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a coal loading and transportation device is used for coal mining, including a support frame 1, a conveyor belt 3 is provided on the top of the support frame 1, a dust suppression mechanism 2 is provided on the top of the corresponding two side walls of the support frame 1 for dust suppression and recovery of dust-laden gas that is dispersed during coal transportation, and a coal sample collection mechanism 6 is provided at the end of the support frame 1 for periodically sampling the coal during transportation. The coal sample collection mechanism 6 includes a fixed frame 14 and a collection box 10. The fixed frame 14 is fixedly installed at the end of the support frame 1, and the collection box 10 for coal sampling is provided inside the fixed frame 14. The end of the collection box 10 is provided with a discharge port.

[0018] Please see Figure 1The dust suppression mechanism 2 includes a support rod 19, a water outlet pipe 20, a spray nozzle 21, and a recovery tank 22. The recovery tank 22 is fixed to the corresponding two side walls of the support frame 1, and the cross-section of the recovery tank 22 is V-shaped. The support rod 19 is fixed at equal intervals to the top of the recovery tank 22 on the side away from the support frame 1, and the end of the support rod 19 is equipped with a water outlet pipe 20 connected to an external water supply pipe. Spray nozzles 21 are also arranged at equal intervals on the outside of the water outlet pipe 20, and the spray nozzles 21 are arranged facing the inside of the recovery tank 22.

[0019] It should be noted that when this utility model is used, the coal is transported by the conveyor belt 3, which is superior to the three conveyor rollers 5 set inside the mounting frame 4. This makes the middle of the conveyor belt 3 concave, thereby preventing the coal from falling off the two sides of the conveyor belt 3. During coal transportation, the dust-laden gas that is dispersed from both sides is sprayed through multiple spray nozzles 21 on the water outlet pipe 20, so that the dust is dissolved in water and recycled in the recycling tank 22. This not only avoids water accumulation in the work area from affecting personnel movement, but also allows for the recycling of dust. During coal transportation, the drive roller inside the conveyor belt 3 rotates, which drives the active pulley inside the belt box 7 to rotate. Through the transmission connection between the active pulley and the driven pulley, the reciprocating screw 8 rotates. The diameter of the active pulley inside the belt box 7 is smaller than that of the driven pulley, which makes the rotation speed of the reciprocating screw 8 slow. In the initial state, the collection box 10 is located at the end away from the sealing plate 18. Through the threaded connection between the slider 9 and the reciprocating screw 8, the collection box 10 gradually moves towards the sealing plate 18 until the discharge port of the collection box 10 is in close contact with the sealing plate 18. When the collection box 10 moves to one end of the sealing plate 18, it can sample and collect the coal at the end of the conveyor belt 3. The collected material is sealed inside the collection box 10 by the sealing plate 18. After collection is completed, the collection box 10 returns to its initial position and is disconnected from the sealing plate 18, causing the sample collected in the collection box 10 to fall out and be collected. Then, with the rotation of the reciprocating screw 8, the next round of sampling continues.

[0020] Please see Figure 2 A reciprocating screw 8 is rotatably connected to the fixed frame 14 via bearings. A belt box 7 is fixedly installed on the side wall of the support frame 1 at one end of the fixed frame 14. The input shaft end of the belt box 7 is fixedly connected to the central shaft of the drive roller inside the conveyor belt 3. The output shaft end of the belt box 7 is fixedly connected to the reciprocating screw 8. A slider 9 is threadedly connected to the outside of the reciprocating screw 8. A connecting rod 13 is fixedly connected to the bottom of the slider 9. The bottom of the connecting rod 13 is fixedly connected to the collection box 10. The collection box 10 is located below the end of the conveyor belt 3.

[0021] It should be noted that a drive pulley and a driven pulley are provided inside the belt box 7, and the drive pulley and the driven pulley are connected by a transmission. The diameter of the drive pulley is smaller than that of the driven pulley. The central shaft of the drive pulley is fixedly connected to the central shaft of the drive roller inside the conveyor belt 3, and the central shaft of the driven pulley is fixedly connected to the reciprocating screw 8. When the drive roller drives the conveyor belt 3 to transport coal, it can drive the reciprocating screw 8 to rotate. Through the threaded connection between the slider 9 and the reciprocating screw 8, it can drive the movement of the collection box 10.

[0022] Please see Figure 2 A fixing rod 11 is fixedly connected between the two corresponding inner walls of the fixing frame 14, and a limiting groove 12 is opened in the fixing rod 11. The connecting rod 13 is slidably connected in the limiting groove 12. A guide rod 15 is fixedly connected between the two corresponding inner walls of the fixing frame 14. A guide hole is opened in the slider 9 on the outside of the reciprocating screw 8. The guide rod 15 is slidably connected in the guide hole of the slider 9.

[0023] It should be noted that the dual design of the limiting groove 12 and the guide rod 15 ensures the stability of the collection box 10's movement and prevents it from shaking.

[0024] Please see Figure 3 The fixing rod 11 is fixedly connected to the mounting rod 17 at equal intervals at one end of the belt box 7, and the mounting rod 17 is in an L-shaped structure. The end of the mounting rod 17 is fixedly connected to the sealing plate 18, and the discharge port of the collection box 10 is in contact with the sealing plate 18.

[0025] It should be noted that the sealing plate 18 can block the outlet of the collection box 10 during the coal sampling process to prevent material overflow. When the collection box 10 finishes collecting coal and moves to the end away from the sealing plate 18, the outlet of the collection box 10 is exposed to the outside, allowing the internal material to be discharged under gravity.

[0026] Please see Figure 1 Multiple mounting frames 4 are installed on the top of the support frame 1, and three conveying rollers 5 are rotatably connected inside the mounting frame 4 via bearings. The conveying rollers 5 at both ends of the mounting frame 4 are symmetrically arranged, and the conveying rollers 5 at both ends of the mounting frame 4 are all sloping structures. The conveying roller 5 in the middle of the mounting frame 4 is horizontally arranged.

[0027] It should be noted that transporting coal via the conveyor belt 3 is superior to the three conveyor rollers 5 installed inside the mounting frame 4, which makes the middle of the conveyor belt 3 concave, thereby preventing coal from falling off the sides of the conveyor belt 3.

[0028] Please see Figure 1 and Figure 2A retractable protective sleeve 16 is symmetrically provided on the outer side of the reciprocating screw 8. One end of the retractable protective sleeve 16 is fixedly connected to the inner wall of the fixed frame 14, and the other end of the retractable protective sleeve 16 is fixedly connected to the slider 9.

[0029] It should be noted that the retractable protective sleeve 16 can effectively protect the core transmission components and extend the equipment's lifespan.
