A suction assembly for a mine ditcher

Abstract

A sludge suction component for a mining ditch cleaning machine includes a movable ditch cleaning platform. A fixed support rod is installed at one end of the platform in the forward direction. The fixed support rod is rotatably connected to a telescopic device extending away from the ditch cleaning platform. This telescopic device is hydraulically driven and rotates in a vertical plane. A sludge suction pipe extends above the telescopic device and moves and rotates synchronously with it. A bottom valve is installed at the extended end of the suction pipe to prevent backflow. The lowest point of the extended end of the suction pipe can be lower than the ditch cleaning platform. This invention, by incorporating a fixed support rod, a telescopic device, and a hydraulic system, along with a telescopic suction pipe, allows for flexible adjustment of the working length and pitch angle of the suction pipe. This ensures that the bottom valve of the suction pipe remains in contact with the ditch bottom at varying depths and uneven surfaces, enabling efficient and thorough sludge suction from the ditch, thus improving the completeness of dredging and operational efficiency.

Description

Technical Field

[0001] This utility model relates to the field of coal-water separation equipment technology, specifically to a mud suction component for a mine ditch cleaning machine. Background Technology

[0002] Numerous surface drainage ditches are installed around coal mine industrial sites, coal storage yards, coal washing plants, and mining roads to discharge rainwater and industrial wastewater. These ditches are exposed to the elements for extended periods, and the collected water contains large amounts of solid particles such as coal dust, ash, and silt. These particles gradually deposit at the bottom of the ditches, forming solid sludge. This accumulated sludge severely clogs the ditches, weakening their drainage capacity.

[0003] Currently, the most common method for dredging surface drainage ditches is still manual cleaning, where workers use shovels to dig out the silt. This method is extremely inefficient, labor-intensive, and creates a poor working environment, making it unsuitable for the high-efficiency operations required in modern coal mines. Although some small and medium-sized mechanical dredging equipment exists, such as wheeled tractors equipped with buckets, they are mainly suitable for wide open channels and are ineffective at cleaning corners and edges, leaving many blind spots and making implementation extremely inconvenient. Utility Model Content

[0004] To address the problems of low efficiency and incomplete cleaning in traditional manual cleaning methods, as well as the issues of poor cleaning effect and numerous dead corners in machine cleaning, this utility model provides a mud suction component for a mining ditch cleaning machine.

[0005] The technical solution of this utility model is as follows: A mud suction assembly for a mining ditch cleaning machine includes a movable ditch cleaning machine platform. A fixed support rod is provided at one end of the ditch cleaning machine platform in the forward direction. The fixed support rod is rotatably provided with a telescopic device that extends away from the end of the ditch cleaning machine platform. The telescopic device can be driven by a hydraulic device provided on the ditch cleaning machine platform and rotate in a vertical plane. Above the telescopic device is a suction pipe extending out of the telescopic device. The suction pipe can move and rotate synchronously with the telescopic device, and one end of the suction pipe is equipped with a bottom valve to prevent backflow. The minimum height of the extension end of the suction pipe can be lower than the ditch cleaning machine platform.

[0006] To improve the adaptability of the adjustment equipment, the extension length of the suction pipe relative to the telescopic device can be adjusted.

[0007] Furthermore, in the mud suction assembly of the mining ditch cleaning machine described above, the mud suction pipe is made of a flexible material, and the extended end can hang down naturally.

[0008] Preferably, the suction pipe extending from the telescopic device is arc-shaped under its own weight and the weight of the bottom valve.

[0009] To remove metallic impurities from the ditch, a magnetic block is connected to the lower end of the telescopic device away from the fixed support rod via a rope connector.

[0010] Furthermore, in the mud suction assembly of a mining ditch cleaning machine as described above, the vertical length of the rope connector is greater than or equal to the vertical height of the telescopic device in its horizontal state.

[0011] In order to stabilize the state of the magnetic block when it is not adsorbed, the magnetic block is magnetically attracted to the fixed support rod when it is not in operation.

[0012] In order to provide a power source for the equipment, it also includes a pump body that provides the power source, and the pump body is connected to the end of the sludge suction pipe that is not equipped with a bottom valve.

[0013] The beneficial effects of this utility model are as follows: This utility model, by setting a fixed support rod, a telescopic device and a hydraulic device, and in conjunction with a telescopic suction pipe, can flexibly adjust the working length and pitch angle of the suction pipe, so that the bottom valve of the suction pipe can always be in contact with the bottom of the ditch of different depths and uneven surfaces, enabling efficient and thorough suction of sludge in the ditch, thus improving the thoroughness of dredging and work efficiency.

[0014] In addition, by using a flexible material suction pipe, this utility model can adapt to bending deformation when the telescopic device is adjusted. This not only better conforms to the contour of the ditch bottom and improves the suction efficiency, but also effectively buffers accidental collisions with obstacles at the bottom of the ditch, reducing the risk of equipment damage and effectively improving the adaptability and durability of the components under complex working conditions.

[0018] Example like Figure 1-3 The mud suction component of a mining ditch cleaning machine is shown to address the problems of low efficiency and high labor costs associated with manual dredging methods, as well as the numerous dead spots and poor adaptability of traditional dredging equipment. This embodiment provides a mud suction component for a mining ditch cleaning machine, including a movable ditch cleaning machine platform 1. A fixed support rod 21 is provided at one end of the ditch cleaning machine platform 1 in the forward direction. The fixed support rod 21 is vertically installed on the upper surface of the ditch cleaning machine platform 1 and is perpendicular to the platform 1. A telescopic device 22, capable of rotating vertically around the fixed support rod 21 away from the platform 1, is provided at the other end of the fixed support rod 21. The fixed support rod 21 and the telescopic device 22 are connected by a rotating base, thereby adjusting the rotation angle of the telescopic device 22.

[0019] A suction pipe 3 is fixedly installed above the telescopic device 22. To ensure the stability of the suction pipe 3 during operation and reduce vibration and displacement, the suction pipe 3 is fixedly installed above the telescopic device 22 by clamps. The end of the suction pipe 3 away from the ditch cleaning machine platform 1 extends outward along the telescopic device 22. In addition, a bottom valve 4 is provided at the extended end of the suction pipe 3 to prevent backflow. In order to filter large particles of impurities, the bottom valve 4 is a hinged one-way valve with a filter screen on its valve disc. In this embodiment, the aperture of the filter screen is 5-10 mm, which can effectively prevent sludge backflow and filter large debris, avoiding blockage of the suction pipe 3 and ensuring the continuity and efficiency of dredging operations. When the pump body 6 is working, the valve disc opens under negative pressure; when it stops working, the valve disc automatically closes under the action of gravity and backflow pressure to prevent sludge in the pipe from flowing back into the ditch.

[0020] To more effectively perform dredging operations and improve the adaptability of the suction pipe 3 to ditches of different depths, a hydraulic device 23 is installed on one side of the fixed support rod 21. In this embodiment, the hydraulic device 23 is a hydraulic cylinder. The hydraulic device 23 is located on the side of the fixed support rod 21 near the dredging machine platform 1 and is rotatably connected to the fixed support rod 21. The other end of the hydraulic device 23 is rotatably connected to the end of the rotating base near the dredging machine platform 1 via a rotating base. The hydraulic device 23 adjusts the pitch angle of the telescopic device 22 by extending and retracting, thereby controlling the vertical height and position of the end of the suction pipe 3 equipped with the bottom valve 4 to adapt to ditches of different depths and shapes. To improve the adaptability of the suction pipe 3 to different areas of the ditch, the hydraulic device 23 drives the telescopic device 22 to rotate within the range of 0-35 degrees, precisely adjusting the working angle of the suction pipe 3.

[0021] To ensure that the suction pipe 3 can move synchronously with the telescopic device 22, the suction pipe 3 in this embodiment is made of a flexible material, specifically abrasion-resistant rubber or TPU. In this embodiment, the suction pipe 3 is made of abrasion-resistant rubber. This flexible design allows the suction pipe 3 to adapt to the extension and angle adjustment of the telescopic device 22, thus better conforming to corners, edges, and other dead-end areas in the ditch, significantly improving cleaning coverage and operational efficiency.

[0022] To prevent metal inside the ditch from affecting the machine through adsorption, a magnetic block 5 is provided at the end of the telescopic device 22 away from the fixed support rod 21. The magnetic block 5 is connected to the fixed support rod 21 by a rope connector. In this embodiment, the telescopic device 22 and the magnetic block 5 are connected by a chain link. When the telescopic device 22 is retracted, the magnetic block 5 can be adsorbed onto the fixed support rod 21, which not only facilitates the storage and transportation of the equipment, but also avoids collision between the magnetic block 5 and the equipment.

[0023] In order to provide power to the equipment, a pump body 6 is also installed in the equipment. The pump body 6 is located at the end of the sludge suction pipe 3 that is not equipped with the bottom valve 4. The sludge in the ditch is continuously sucked out and transported to the designated collection point through the negative pressure.

[0024] Please refer to the appendix. Figure 1-3 When using this device, first, the ditch cleaning machine platform 1 is driven to the side of the ditch. Based on the actual depth, slope, and sludge distribution of the ditch, the telescopic device 22 is extended or retracted to initially adjust the working radius of the suction pipe 3. The hydraulic device 23 is then activated, driving the telescopic device 22 to rotate around the fixed support rod 21, thereby adjusting the pitch angle of the suction pipe 3. This brings the bottom valve 4 into contact with the bottom of the ditch. The pump body 6, connected to the suction pipe 3, is then activated. The negative pressure generated by the pump body 6 is transmitted to the bottom valve. Under this negative pressure, the bottom valve 4 is open, allowing the sludge from the bottom of the ditch to enter the suction pipe 3 through the filter screen inside the bottom valve 4. The pump body 6 then continuously transports the sludge to the storage tank.

[0025] During the cleaning process, when encountering protruding objects on the ditch wall or complex terrain, the flexibility of the suction pipe 3 can be utilized to adaptively bend while maintaining suction, skillfully bypassing obstacles to achieve thorough cleaning of the bottom of the ditch, especially in corners and dead angles. After the cleaning task is completed, the lifting device 23 is first retracted. At this time, under the action of the lifting device 23, the telescopic device 22 rotates around the fixed support rod 21, lifting the suction pipe 3 to detach it from the ditch. Subsequently, the telescopic device 22 drives the suction pipe 3 to retract, and the magnetic block 5 is attracted and fixed to the corresponding part on the fixed support rod 21, ensuring the safety and stability of the equipment during movement.
