Description

Technical Field

[0001] This utility model relates to the field of mining conveying equipment technology, and in particular to a chute anti-blocking device. Background Technology

[0002] In coal mining and transportation, chutes are essential equipment for conveying bulk materials such as coal and gangue. Their main function is to smoothly transport coal mined underground from a higher position to lower transport equipment or storage silos. Chutes rely on gravity to allow materials to slide along their inner walls, and are widely used in all stages of coal mine production.

[0003] However, in actual coal mine production, due to the humid working environment of the chute and the high moisture content of the coal, coal easily adheres to the inner wall of the chute during transportation, gradually accumulating and causing blockages. At the same time, a large amount of coal dust and gangue generated during transportation mixes with these fine particles, which also easily adhere to the inner wall of the chute, exacerbating the risk of material accumulation and blockages, further affecting transportation efficiency and production safety. Once a blockage occurs, workers need to stop the machine for cleaning, which not only increases labor intensity but also affects the normal production process and reduces work efficiency.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a chute anti-clogging device, comprising a chute body and a vibration mechanism, wherein the vibration mechanism includes an installation plate fixedly installed on the bottom wall of the outer side of the chute body, a rotating cavity is provided inside the installation plate, a telescopic cavity is connected to the top of the rotating cavity, a telescopic plate is slidably connected inside the telescopic cavity, a driving assembly is provided below the telescopic plate, a connecting plate is fixedly connected to the top of the telescopic plate, the top of the connecting plate penetrates the bottom wall of the chute body and extends to its upper surface where a vibration plate is fixedly connected, and a liner is movably installed on the upper surface of the vibration plate.

[0008] In a preferred embodiment of the chute anti-blocking device of this utility model, the driving component includes a servo motor fixedly installed inside the rear end of the mounting plate. The output end of the servo motor is connected to a rotating shaft via a coupling. The front end of the rotating shaft extends into the rotating cavity and is fixedly connected to an eccentric wheel. The upper surface of the eccentric wheel abuts against the bottom surface of the telescopic plate.

[0009] In a preferred embodiment of the chute anti-clogging device of this utility model, a bearing is provided at the connection between the rotating shaft and the inner wall of the mounting plate, and the rotating shaft is rotatably connected to the inner wall of the mounting plate through the bearing.

[0010] In a preferred embodiment of the chute anti-clogging device of this utility model, positioning blocks are fixedly provided on both the left and right sides of the top of the inner wall of the vibrating plate, and the liner is slidably connected to the inner side of the vibrating plate and located below the positioning blocks.

[0024] Example

[0025] Reference Figures 1 to 5This embodiment provides a chute anti-clogging device, including a chute body 100 and a vibration mechanism 200. The chute body 100 is used to transport bulk materials such as coal and gangue. Limiting grooves 101 are symmetrically opened at both ends of its upper surface. Each limiting groove 101 is equipped with a buffer assembly 102. The buffer assembly 102 consists of a telescopic spring 102a fixedly connected to the bottom wall of the limiting groove 101 and a limiting plate 102b fixedly connected to its top. The inner side of the limiting plate 102b is fixedly connected to the outer wall of the liner 206. Its main function is to absorb and buffer the impact force generated by the liner 206 during vibration, protect the chute body 100 from vibration damage, and ensure the stable operation of the liner 206.

[0026] The vibration mechanism 200 is fixedly installed on the outer bottom wall of the tank 100. Its main function is to generate vibration to prevent coal and gangue from adhering to and accumulating on the inner wall of the tank, thereby preventing blockage. The vibration mechanism 200 includes a mounting plate 201, a drive assembly 203, a telescopic plate 202, a connecting plate 204, a vibrating plate 205, and a liner plate 206. The mounting plate 201 has a rotating cavity 201a and a telescopic cavity 201b communicating with it, used to accommodate and support the drive assembly 203 and the telescopic plate 202. The telescopic plate 202 is slidably connected inside the telescopic cavity 201b, and the drive assembly 203 is located below it.

[0027] The drive assembly 203 includes a servo motor 203a fixedly mounted inside the rear end of the mounting plate 201. The output end of the servo motor 203a is connected to a rotating shaft 203b via a coupling. The front end of the rotating shaft 203b extends into the rotating cavity 201a and is fixedly connected to an eccentric wheel 203c. The upper surface of the eccentric wheel 203c abuts against the bottom surface of the telescopic plate 202. A bearing 203d is provided at the connection between the rotating shaft 203b and the inner wall of the mounting plate 201. The rotating shaft 203b is rotatably connected to the inner wall of the mounting plate 201 via the bearing 203d, ensuring smooth rotation of the shaft.

[0028] A connecting plate 204 is fixedly connected to the top of the telescopic plate 202. The connecting plate 204 penetrates the bottom wall of the trough 100 and extends to its upper surface, where a vibrating plate 205 is fixedly connected. A liner 206 is movably installed on the upper surface of the vibrating plate 205. Positioning blocks 207 are fixedly installed on both the left and right sides of the top of the inner wall of the liner 206. The liner 206 is fixedly connected to the positioning blocks 207 by bolts and slidably connected to the inner side of the vibrating plate 205, located below the positioning blocks 207. During vibration, the liner 206 can effectively shake off wet coal and coal dust adhering to the inner wall of the trough, preventing material accumulation and blockage. At the same time, the inclined installation ensures that it does not hinder the normal conveying of materials during up-and-down vibration.

[0029] When the servo motor 203a starts, it drives the eccentric wheel 203c to rotate via the shaft 203b. The rotation of the eccentric wheel 203c causes the telescopic plate 202 to reciprocate up and down, which in turn drives the vibrating plate 205 to vibrate vertically via the connecting plate 204. The vibration of the vibrating plate 205 is transmitted to the inner wall of the chute through the liner 206, effectively preventing material adhesion and accumulation. At the same time, the buffer assembly 102 absorbs the impact force generated by the vibration of the liner 206, ensuring the stability and durability of the equipment. Through the coordinated work of its components, the entire device can effectively prevent chute blockage in complex coal mine production environments, improve material conveying efficiency, reduce downtime for cleaning, extend equipment life, and enhance production safety and overall efficiency.
