[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] like Figures 1-5 As shown, a coal mine coal bunker inlet unblocking device is installed on the coal bunker inlet pipe 3. The coal bunker inlet pipe generally includes two parts: an upper conical discharge section and a lower straight pipe section. The device of this application includes an installation sleeve 1, a connecting frame 32, an air hammer 2, a gear ring 25, and a motor 21.
[0023] The mounting sleeve 1 is fitted onto the straight section of the coal bunker inlet pipe, adjacent to the tapered section of the coal bunker inlet pipe. The lower inner side of the mounting sleeve 1 is fixedly welded to the inner side of the coal bunker inlet pipe via a connecting rod. A ring rail 33 and a mounting base 24 for mounting the motor 21 are fixedly connected to the outer wall of the mounting sleeve 1. Two connecting sleeves 31 are slidably connected to the ring rail 33. The connecting frame 32 is an inverted U-shaped frame, with its outer side located outside the mounting sleeve 1 and fixedly connected to the connecting sleeves 31. Its inner side is located between the mounting sleeve 1 and the coal bunker inlet pipe 3. An air hammer 2 is mounted on the top surface of the connecting frame 32, with the hammer head facing the coal bunker inlet pipe. The conical section of the inlet pipe has a gear ring 25 fitted outside the mounting sleeve 1 and fixedly connected to the outer side of the connecting frame 32. A drive gear 23 is installed on the output shaft 22 of the motor 21. The drive gear 23 meshes with the gear ring 25 to drive the gear ring to rotate. After starting, the hammer head extends and can strike the wall of the conical section of the coal bunker inlet pipe. Under the drive of the motor, it can strike around the coal bunker inlet pipe, thereby realizing vibration clearing of the conical discharge section of the coal bunker inlet pipe. It also includes a reinforcing ring 36, which is installed inside the mounting sleeve 1. The top surface of the reinforcing ring 36 is provided with a sliding groove, and the lower end of the inner side of the connecting frame cooperates with the sliding groove.
[0024] The front and rear sides of the inner side of the connecting frame 32 are matched with the curvature of the corresponding mounting sleeve 1 and the coal bunker inlet pipe 3, ensuring that the inner side of the connecting frame 32 can move smoothly between the mounting sleeve 1 and the coal bunker inlet pipe 3, and also ensuring that it can move within the reinforcing ring 36, which provides support for it.
[0025] The side wall adjacent to the coal bunker inlet pipeline 3 on the inner side of the connecting frame 32 is fixedly connected with a hitting block 38, the top surface of the hitting block 38 is arc-shaped, and the hitting block 38 further comprises a hitting mechanism, which comprises a fixed frame 35, a spring 311, a moving block 39, a pressing plate 310, a clearing block 37, the fixed frame 35 is fixedly installed on the coal bunker inlet pipeline 3, the moving block 39 is slidably connected to the fixed frame 35, the rear end of the moving block 39 is fixedly connected with the pressing plate 310 in a vertical manner, the front end of the moving block 39 is fixedly connected with the clearing block 37, the front end of the clearing block is arc-shaped, the spring 311 is installed between the pressing plate 310 and the fixed frame 35, the clearing block 37 is matchedly and penetratingly arranged on the installation hole of the coal bunker inlet pipeline 3, the hitting block 38 cooperates with the pressing plate 310, the contact surface between the hitting block 38 and the pressing plate 310 is arc-shaped, and the curvature of the arc-shaped surface determines the stroke of the clearing block. The pressing plate of the embodiment is basically flat, and the amplitude thereof is relatively small. According to actual use requirements, the curvature of the contact surface can be flexibly set. However, when the clearing block is at the nearest and farthest positions, the clearing block is located on the wall of the coal bunker inlet pipeline, thereby preventing the clearing block from sliding out of the wall of the coal bunker inlet pipeline.
[0026] When the equipment is actually used, a dustproof shell can be installed outside, which is not shown in the drawings of the present application.
[0027] When used, the device is installed on the existing coal bunker inlet pipeline. When the straight pipe section of the coal bunker inlet pipeline is stagnant or the flow rate is reduced, the motor drives the gear ring to rotate, thereby driving the connecting frame to rotate. When the hitting block on the inner side of the connecting frame rotates with the connecting frame, the hitting block will be in contact with the pressing plate and be pressed, thereby periodically pushing the clearing block to push the coal blocks in the pipeline, thereby opening the mutual clamping of the coal blocks. An air hammer is installed on the upper part of the connecting frame, and the air hammer is located at the connection between the conical discharge section and the straight pipe section of the coal bunker inlet pipeline. The air hammer can be used to knock the pipeline, thereby preventing the coal blocks from being blocked. Since the connecting frame is rotating, the air hammer can knock each point on the outer periphery of the pipeline, and the clearing effect is better. The above two functions can be used alone or simultaneously according to actual conditions. The driving mode of the air hammer is conventional, that is, the air supply pipeline and the wire are directly used for driving. At this time, in order to simplify the equipment and ensure stability, a gas source and a power source need to be arranged on both sides of the equipment respectively, the motor reciprocatingly drives the gear ring, thereby ensuring that the wire is not entangled, and since the clearing device is not continuously and long-time operated, a gas tank and a battery can also be provided in the form of a gas tank and a battery, and the gas tank and the battery are fixed on the connecting frame.
