Description

Technical Field

[0001] This utility model relates to the technical field of scraper conveyors for coal mine transportation, and in particular to a scraper conveyor for coal mines that is easy to assemble. Background Technology

[0002] Scraper conveyors are transport machinery used in coal mine working faces. They are mainly used for transporting coal in coal faces and mining roadways, and can also be used in coal roadways and semi-coal-rock roadway excavation faces. Scraper conveyors have advantages such as transport capacity not being affected by the size and moisture of the load, small machine height for easy loading, and convenient machine length adjustment.

[0003] Existing scraper conveyors for coal mines are generally used for short-distance coal transportation. During transportation, coal is transferred by cranes or loaders, then dumped onto the scraper conveyor for further transport. To reduce coal spillage during dumping, a hopper is typically welded above the scraper conveyor's inlet. The hopper collects the coal, causing it to fall onto the conveyor. To increase stability, existing hoppers are usually welded to the scraper conveyor's inlet. To reduce transportation costs, the scraper conveyor needs to be moved after transporting coal in a specific area. The hopper and support are typically an integrated structure, resulting in significant weight during movement and making disassembly, installation, and relocation inconvenient, thus causing inconvenience in use.

[0004] Therefore, a scraper conveyor for coal mines that is easy to assemble is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a scraper conveyor for coal mines that is easy to assemble in order to solve the above-mentioned problems. It improves the problem that after the transportation of coal in a certain area is completed, the scraper conveyor needs to be transferred. Generally, the hopper and the support are an integrated structure, which has a large weight during the transfer process, making it inconvenient to disassemble, install and transfer.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a scraper conveyor for coal mines that is easy to assemble, comprising: a scraper conveyor body, support frames fixedly connected to both sides of the scraper conveyor body, support plates fixedly connected above the two support frames, a hopper movably connected between the two support plates, and a guide hopper movably connected to one side of the hopper;

[0007] A rotating shaft is movably connected to the inside of the hopper, and a closing plate is movably connected to the surface of the rotating shaft. The closing plate extends obliquely downward to the bottom of the hopper.

[0008] A support platform is fixedly connected inside the hopper. An electric actuator is fixedly connected above the support platform. The output end of the electric actuator is driven by two connecting rods. The upper part of the two connecting rods supports the closing plate.

[0009] Preferably, limit blocks are fixedly connected to both sides of the hopper, and crossbars are movably connected inside the two limit blocks, with both ends of the multiple crossbars movably inserted into the interior of the two support plates.

[0010] Preferably, fixing blocks are movably connected to both sides of the two support plates, and one side of each of the fixing blocks is in contact with the crossbar.

[0011] Preferably, a connecting rod is fixedly connected to the lower part of the guide hopper, and a support rod is movably connected between the connecting rod and the hopper.

[0012] Preferably, a guide block is fixedly connected to the inner wall of the hopper, the guide block is located above the rotating shaft and extends obliquely towards the side close to the closing plate.

[0013] Preferably, a control panel is fixedly connected to the outer wall of the hopper, and an electric wire is electrically connected to one side of the control panel. One end of the electric wire passes through the inner wall of the hopper and is electrically connected to the electric push rod.

[0014] Preferably, pressure plates are fixedly connected to both sides of the scraper body, and guide wheels and pressure wheels are movably inserted into the interior of the pressure plates. The pressure wheels are located above the guide wheels, the two guide wheels rotate on both sides of the scraper of the scraper body, and the two pressure wheels rotate above the scraper of the scraper body.

[0015] The beneficial effects of this utility model are:

[0016] 1. The hopper is used for collection and guidance. The electric actuator pulls down the crossbar to separate the closing plate from the hopper. The coal falls into the conveyor belt of the scraper conveyor body through the opening between the hopper and the closing plate. During assembly and disassembly, the support frame and the scraper conveyor body are fixed with bolts. The support plate limits the limit block through the crossbar. The hopper uses gravity to make the crossbar embed into the limit block. After the fixing block is removed from the support plate, the hopper can be quickly lifted to achieve rapid separation of the hopper from the scraper conveyor body, which greatly increases the efficiency of transportation and disassembly.

[0017] 2. The hopper collects the coal and discharges it through the lower outlet. The coal first comes into contact with the closing plate. When the closing plate is closed, it seals off the bottom of the hopper. When the closing plate is open, it guides the coal. After the coal falls onto the closing plate, it slides down the surface of the closing plate at a reduced speed. By reducing the sliding speed and the falling height of the coal, the impact force on the scraper plate of the scraper body is reduced, which increases the service life of the scraper body.

[0023] 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.

[0024] In practical implementation: such as Figure 1-4 As shown, a scraper conveyor for coal mines that is easy to assemble includes: a scraper conveyor body 1, a rotating shaft 500, and a support platform 700. Support frames 200 are fixedly connected to both sides of the scraper conveyor body 1. Support plates 300 are fixedly connected above each of the two support frames 200. A hopper 400 is movably connected between the two support plates 300. A guide hopper 404 is movably connected to one side of the hopper 400. The rotating shaft 500 is movably connected to the inside of the hopper 400. A closing plate 600 is movably connected to the surface of the rotating shaft 500. The closing plate 600 extends downward at an angle to the bottom of the hopper 400. The support platform 700 is fixedly connected to the inside of the hopper 400. An electric push rod 701 is fixedly connected above the support platform 700. The output end of the electric push rod 701 drives two connecting rods 702. The upper part of the two connecting rods 702 supports the closing plate 600.

[0025] It should be noted that the scraper conveyor body 1 is composed of a drive unit, a trough, and auxiliary components such as the head, position, and baffles. The scraper conveyor body 1 is a mechanical device that uses a scraper chain to continuously transport bulk materials in a closed trough. It is widely used in mining, metallurgy, building materials, chemical and other fields.

[0026] When it is necessary to transport coal from the mine, the scraper conveyor body 1 is installed first. The trough needs to be installed according to the actual transportation requirements. The transportation distance of the scraper conveyor body 1 can be changed by splicing multiple troughs. After the scraper conveyor body 1 is installed, two support frames 200 are fixed to the outer walls of both sides of the scraper conveyor body 1 with bolts. The support frames 200 extend downward to both sides, which can increase the contact area between the support frames 200 and the outer wall of the scraper conveyor body 1 and improve stability.

[0027] The support plate 300 is supported above the two support frames 200. The support plate 300 is mainly used to limit the hopper 400 and fix the hopper 400 directly above the scraper of the scraper body 1. The internal space of the hopper 400 gradually increases upward, and a movable guide hopper 404 is installed in the direction away from the scraper body 1. The guide hopper 404 has a certain slope, which can assist the sliding direction of the coal mine and make it easier for workers to dump the coal.

[0028] The hopper 400 collects the coal and discharges it through the lower outlet. The coal first comes into contact with the closing plate 600. When the closing plate 600 is closed, it seals off the area below the hopper 400. When the closing plate 600 is open, it guides the coal. After the coal falls onto the closing plate 600, it slides down the surface of the closing plate 600 at a reduced speed. By reducing the sliding speed and the falling height of the coal, the impact force on the scraper plate under the scraper body 1 is reduced, which increases the service life of the scraper body 1. The assembly method of the support frame 200, support plate 300 and hopper 400 allows for quick disassembly of the hopper 400. After disassembly, it can be transferred separately, which greatly improves the disassembly and assembly efficiency of the scraper body 1.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, limit blocks 401 are fixedly connected to both sides of the hopper 400. Crossbars 402 are movably connected inside the two limit blocks 401. Both ends of the multiple crossbars 402 are movably inserted into the interior of the two support plates 300. Fixing blocks 403 are movably connected to both sides of the two support plates 300. One side of the multiple fixing blocks 403 is in contact with the crossbars 402.

[0030] The support plate 300 is T-shaped, and the support plate 300 extending to both sides can increase the structural support strength. First, multiple crossbars 402 are placed inside the grooves on both sides of the support plate 300. Then, the hopper 400 is lifted and suspended between the multiple crossbars 402. The limiting blocks 401 installed on both sides of the hopper 400 will first contact the crossbars 402. The slots on both sides of the limiting blocks 401 extend downwards at an angle away from the hopper 400. When the crossbars 402 are placed inside the limiting blocks 401, due to the weight of the hopper 400, the crossbars 402 will be close to the upper inner wall of the limiting blocks 401, increasing stability. Then, multiple fixing blocks 403 are clamped on both sides of the support plate 300. Bolts are used to pass through the fixing blocks 403 and abut against the support plate 300 to fix the fixing blocks 403. The fixing blocks 403 limit the crossbars 402 inside the support plate 300 to increase stability.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, a connecting rod 406 is fixedly connected to the lower part of the guide hopper 404, and a support rod 405 is movably connected between the connecting rod 406 and the hopper 400. A guide block 407 is fixedly connected to the inner wall of the hopper 400. The guide block 407 is located above the rotating shaft 500 and extends inclined towards the side close to the closing plate 600.

[0032] A hinge is installed at the connection between the guide hopper 404 and the hopper 400, which allows the guide hopper 404 to rotate along the outer wall of the hopper 400. The bottom of the guide hopper 404 is supported by a connecting rod 406. The lower part of the connecting rod 406 is movably connected to the outer wall of the hopper 400 through a support rod 405. The support rod 405 consists of a threaded rod and a threaded sleeve. The internal threads of the two threaded sleeves are opposite. When the threaded rod is rotated in both directions, the length of the support rod 405 can be adjusted to easily change the slope of the guide hopper 404.

[0033] The upper surface of the guide block 407 is inclined upward along the inner wall of the hopper 400, which can reduce the accumulation of coal on the guide block 407 during the falling process. The guide block 407 protects the shaft 500 below, reducing the possibility of the falling coal hitting the shaft 500 and improving the service life of the shaft 500.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, a control panel 800 is fixedly connected to the outer wall of the hopper 400. A wire 801 is electrically connected to one side of the control panel 800. One end of the wire 801 passes through the inner wall of the hopper 400 and is electrically connected to the electric push rod 701.

[0035] The control panel 800 is installed on the outer wall of the hopper 400. It can be installed on the side away from the scraper conveyor body 1 and on the side close to the support plate 300, depending on the actual needs and in a direction that is convenient for operation. After the control panel 800 is installed, the electric push rod 701 is controlled by the control panel 800 and the wire 801. The two connecting rods 702 are composed of two rotatably connected cylinders. The connection point of the two cylinders is located at the bottom of the two cylinders. One end of the two cylinders is rotatably connected to the inner wall of the hopper 400 and the bottom of the closing plate 600, respectively. When the electric push rod 701 is started, the electric push rod 701 pushes the two connecting rods 702 upward to change their shape, which can control the closing and opening between the closing plate 600 and the hopper 400.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, pressure plates 900 are fixedly connected to both sides of the scraper conveyor body 1. Guide wheels 901 and pressure wheels 902 are movably inserted into the interior of the pressure plates 900. The pressure wheels 902 are located above the guide wheels 901. The two guide wheels 901 rotate on both sides of the scraper of the scraper conveyor body 1, and the two pressure wheels 902 rotate above the scraper of the scraper conveyor body 1.

[0037] The scraper of the scraper conveyor body 1 is driven by a chain, which slides on the surface of the scraper conveyor body 1. In order to transfer coal, the scraper conveyor body 1 is usually stopped or placed in a factory in the tilting direction, which generally requires a certain height. This causes one side of the scraper conveyor body 1 to be raised, resulting in the overall scraper conveyor body 1 having a certain tilt angle. During the sliding process, the chain may detach from the upper surface of the scraper conveyor body 1, which requires the correction of the guide wheel 901 and the pressure wheel 902. By restricting the movement of the chain, the stability of coal transportation can be increased.

[0038] In use, the scraper conveyor body 1 is first assembled and installed. Then, the support frame 200 and support plate 300 are installed on the upper sides of the scraper conveyor body 1. Then, the hopper 400 is connected to the crossbar 402 by the limiting block 401, so that the hopper 400 can be fixed directly above the scraper conveyor body 1. The coal is poured into the hopper 400 and collected and guided by the hopper 400. The electric push rod 701 pulls down the crossbar 402 to separate the closing plate 600 from the hopper 400. The coal falls into the conveyor belt of the scraper conveyor body 1 through the opening between the hopper 400 and the closing plate 600.

[0039] During assembly and disassembly, the support frame 200 and the scraper conveyor body 1 are fixed with bolts. The support plate 300 limits the limiting block 401 through the crossbar 402. The hopper 400 uses gravity to embed the crossbar 402 into the limiting block 401. After the fixing block 403 is removed from the support plate 300, the hopper 400 can be quickly lifted, realizing the rapid separation of the hopper 400 from the scraper conveyor body 1, which greatly increases the efficiency of transportation and disassembly.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art. 。
