Description
Technical Field
[0001] This utility model belongs to the technical field of mining equipment, specifically a self-cleaning mining sweeper. Background Technology
[0002] Mining scrapers are key devices installed on belt conveyors. Their core function is to remove residual materials such as coal dust and slag adhering to the surface of the conveyor belt through scrapers, so as to prevent material spillage, protect the belt and idlers from wear, eliminate belt misalignment and fire hazards caused by material accumulation, and thus ensure the efficient, stable and safe continuous operation of the conveying system.
[0003] Patent document CN217229194U describes a mining extrusion belt cleaner, which mainly includes a frame, with extrusion mechanisms installed on both sides of the frame. The extrusion mechanism includes an upper roller and a lower roller, which are rotatably connected to the frame. A scraper is installed between the two extrusion mechanisms on the frame, with the scraper on the upper side of the lower roller. A mud-cleaning mechanism and a drying mechanism are installed on the outer side of the two extrusion mechanisms on the frame. The mud-cleaning mechanism includes a water spray pipe installed on the frame, which is connected to a water inlet pipe and has multiple water nozzles installed on it. The drying mechanism includes an air duct installed on the frame.
[0004] Existing mine sweepers have certain shortcomings in use. Mine sweepers mainly remove residual materials such as coal powder and slag adhering to the surface of the conveyor belt by scraping. After long-term use, residual materials such as coal powder and slag will adhere to the surface of the scraper structure, affecting the cleaning effect of the scraper on the conveyor belt. Mine sweepers do not have a self-cleaning function, which requires users to clean the scraper structure of the mine sweeper, reducing the stability of the mine sweeper when used continuously for a long time.
[0005] In summary, after prolonged use, residual materials such as coal dust and slag will adhere to the surface of the scraper structure in existing mine sweepers, affecting the cleaning effect of the scraper on the conveyor belt and causing the mine sweeper to lack self-cleaning function. Utility Model Content
[0006] This utility model provides a mine sweeper with a self-cleaning function, which can solve the problem that after long-term use, residual materials such as coal powder and slag will adhere to the surface of the scraper structure of existing mine sweepers, affecting the cleaning effect of the scraper on the conveyor belt, and the mine sweeper does not have a self-cleaning function:
[0007] A self-cleaning mine cleaner includes a hopper and a scraper. The scraper is movably installed at the upper middle position of the hopper. The hopper and the scraper are fixed together by two sets of docking brackets, which are respectively installed on the outer surfaces of both ends of the scraper. A cleaning component is movably installed on the outer surface of the scraper's side. The cleaning component includes a movable base and a splicing scraper strip. The splicing scraper strip is movably installed on the upper end of the movable base, and a movable clamp head for use with the scraper is movably installed on the upper end of the splicing scraper strip. One end of the outer surface of the movable clamp head is inclined.
[0008] As a further technical solution of this utility model, the cleaning component has an overall U-shaped structure. An adjusting slider for use with the splicing scraper is movably installed on the upper outer surface of the moving seat. The splicing scraper and the adjusting slider are spliced and fixed together. The moving seat is driven by the first lead screw, so that the splicing scraper of the moving seat moves along the surface of the scraper, thereby cleaning the slag dust adhering to the surface of the scraper.
[0009] As a further technical solution of this utility model, the movable seat is internally movably sleeved with a first lead screw, and the movable seat and the first lead screw are threadedly connected. The two ends of the first lead screw are respectively movably connected to the docking seat. The first lead screw is driven by a motor, so that the first lead screw drives the movable seat through the threaded structure, thereby driving the cleaning part to move as a whole.
[0010] As a further technical solution of this utility model, a guide rod is movably installed on the inner side of the movable seat above the first lead screw. The two ends of the guide rod are respectively connected and fixed to the docking seat. The guide rod, in conjunction with the first lead screw, plays a two-point positioning role for the movable seat, so that the movable seat moves laterally along the guide rod when moving, avoiding changes in the angle of the movable seat and improving its stability during cleaning.
[0011] As a further technical solution of this utility model, the upper outer surface of the scraper is inclined, and the splicing scraper strip and the movable clamping head are movably connected through a limiting groove. When the scraper is installed, both ends of the scraper are respectively inserted into the inner side of the docking seat, so that the surface of the scraper is inserted into the inner side of the cleaning component, and the splicing scraper strip is attached to one side of the outer surface of the scraper. The upper end of the scraper is inclined. In order to ensure that the surface of the scraper can be completely cleaned when the splicing scraper strip moves, a movable clamping head is provided. When the scraper is installed, the movable clamping head is moved outward. After the scraper is installed, the movable clamping head is pushed so that the inclined surface of one end of the movable clamping head is attached to the inclined surface of the scraper, so that the splicing scraper strip and the side of the scraper are fully attached.
[0012] As a further technical solution of this utility model, the cleaning component and the adjusting slider are driven by a second lead screw. The upper end of the moving seat is provided with a sliding groove for use with the adjusting slider. The user can adjust the position of the spliced scraper by rotating the second lead screw according to the thickness of the scraper, so that the second lead screw drives the adjusting slider through the thread structure. The adjusting slider drives the spliced scraper to move, thereby adjusting the position of the spliced scraper to meet the cleaning operation of scrapers of different thicknesses.
[0013] As a further technical solution of this utility model, a docking buckle is fixedly installed on the lower outer surface of the splicing scraper. The splicing scraper and the adjusting slider are spliced and fixed together by the docking buckle. The user can select and install the splicing scraper of the corresponding length according to the length of the scraper by using the docking buckle. After the docking buckle is connected, it is fixed with bolts.
[0014] As a further technical solution of this utility model, a vibrator is fixedly installed on the lower outer surface of the storage hopper, and the inner side of the storage hopper is inclined. By using the vibrator, the slag powder in the storage hopper can be discharged through the internal vibration of the storage hopper.
[0015] As a further technical solution of this utility model, a discharge groove is provided on the outer surface of one end of the storage hopper, and a rotating wheel is provided on one end of the docking seat. By rotating the rotating wheel, the user can drive the docking seat and adjust the tilt angle of the scraper through the docking seat so that the scraper is attached to the lower part of the conveyor belt. When the conveyor belt moves, it plays a role in cleaning the residual slag on its surface.
[0016] As a further technical solution of this utility model, one side of the splicing scraper is provided with a beveled surface, and the entire beveled surface is inclined. By using the beveled surface, the side of the splicing scraper forms a beveled structure. When the splicing scraper cleans the surface of the scraper, the slag powder can be discharged to one side along the beveled surface, thereby improving the performance of the splicing scraper.
[0017] The beneficial effects of this utility model are as follows: By incorporating a cleaning component, this utility model provides a self-cleaning auxiliary function to the mining sweeper during use, improving its stability during prolonged use. During installation, both ends of the scraper are respectively engaged with the inner side of the docking bracket, allowing the scraper surface to insert into the inner side of the cleaning component. The spliced scraper strip adheres to one outer surface of the scraper, and the upper end of the scraper has an inclined structure. To ensure complete cleaning of the scraper surface during scraper strip movement, a movable locking head is provided. Move the movable clamp head outwards. After the scraper is installed, push the movable clamp head so that the inclined surface of one end of the movable clamp head fits against the inclined surface of the scraper, making the spliced scraper strip fit against the side of the scraper. The guide rod and the first screw provide two-point positioning for the movable seat, allowing the movable seat to move laterally along the guide rod during movement. This prevents the movable seat from changing angles and improves its stability during cleaning. The first screw drives the movable seat so that the spliced scraper strip of the movable seat moves along the surface of the scraper, cleaning the slag dust adhering to the surface of the scraper.
[0018] By incorporating spliced scraper strips, the use of this mining sweeper is optimized, providing multiple adjustment options and enhancing its flexibility. Firstly, the user can adjust the position of the spliced scraper strip by rotating the second lead screw, which in turn drives the adjusting slider via a threaded structure. This adjustment slider moves the spliced scraper strip, accommodating scrapers of different thicknesses. Secondly, the user can select and install spliced scraper strips of corresponding lengths using the mating clips. After the clips are engaged, bolts are used to secure them, thus accommodating scrapers of different sizes. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] like Figures 1-3 As shown, a self-cleaning mine cleaner includes a hopper 1 and a scraper 3. The scraper 3 is movably installed at the upper middle position of the hopper 1. The hopper 1 and the scraper 3 are fixed together by two sets of docking seats 5. The two sets of docking seats 5 are respectively installed on the outer surfaces of both ends of the scraper 3. A cleaning component 4 is movably installed on the outer surface of the side of the scraper 3. The cleaning component 4 includes a movable seat 10 and a splicing scraper 11. The splicing scraper 11 is movably installed on the upper end of the movable seat 10, and a movable clamp 13 for use with the scraper 3 is movably installed on the upper end of the splicing scraper 11. One end of the outer surface of the movable clamp 13 is inclined. When in use, the mine cleaner is installed on the lower part of the mine conveyor belt, so that the scraper 3 is attached to the lower surface of the lower conveyor belt. During the operation of the conveyor belt, the scraper 3 scrapes off the slag material on the surface of the conveyor belt.
[0026] The cleaning component 4 has a U-shaped structure. The upper outer surface of the movable seat 10 is movably mounted with a directional slider 12 that works with the splicing scraper 11. The splicing scraper 11 and the directional slider 12 are spliced and fixed together. The movable seat 10 is driven by the first lead screw 8, so that the splicing scraper 11 of the movable seat 10 moves along the surface of the scraper 3, which plays a role in cleaning the slag dust adhering to the surface of the scraper 3.
[0027] The movable seat 10 is internally fitted with a first lead screw 8, and the movable seat 10 and the first lead screw 8 are threadedly connected. The two ends of the first lead screw 8 are respectively movably connected to the docking seat 5. The first lead screw 8 is driven by a motor, so that the first lead screw 8 drives the movable seat 10 through the threaded structure, thereby driving the cleaning component 4 to move as a whole.
[0028] A guide rod 9 is movably installed on the inner side of the movable seat 10 above the first lead screw 8. The two ends of the guide rod 9 are respectively connected and fixed to the docking seat 5. The guide rod 9, in conjunction with the first lead screw 8, provides two-point positioning for the movable seat 10, allowing the movable seat 10 to move laterally along the guide rod 9 during movement, thus preventing the movable seat 10 from changing angle and improving its stability during cleaning.
[0029] The upper outer surface of the scraper 3 is inclined. The splicing scraper 11 and the movable clamp 13 are connected by a limiting groove 16. When the scraper 3 is installed, both ends of the scraper 3 are respectively inserted into the inner side of the docking seat 5, so that the surface of the scraper 3 is inserted into the inner side of the cleaning component 4, and the splicing scraper 11 is attached to one side of the outer surface of the scraper 3. The upper end of the scraper 3 is inclined. In order to ensure that the splicing scraper 11 can completely clean the surface of the scraper 3 when it moves, a movable clamp 13 is provided. When the scraper 3 is installed, the movable clamp 13 is moved outward. After the scraper 3 is installed, the movable clamp 13 is pushed so that the inclined surface of one end of the movable clamp 13 is attached to the inclined surface of the scraper 3, so that the splicing scraper 11 and the side of the scraper 3 are attached together.
[0030] The cleaning component 4 and the adjusting slider 12 are driven by the second lead screw 14. The upper end of the moving seat 10 is provided with a groove for use with the adjusting slider 12. The user can adjust the position of the splicing scraper 11 by rotating the second lead screw 14 according to the thickness of the scraper 3, so that the second lead screw 14 drives the adjusting slider 12 through the thread structure. The adjusting slider 12 drives the splicing scraper 11 to move, thereby adjusting the position of the splicing scraper 11 to meet the cleaning operation of scrapers 3 of different thicknesses.
[0031] A mating clip 15 is fixedly installed on the lower outer surface of the splicing scraper 11. The splicing scraper 11 and the adjusting slider 12 are spliced and fixed together by the mating clip 15. The user can select and install the splicing scraper 11 of the corresponding length according to the length of the scraper 3 by using the mating clip 15. After the mating clip 15 is mated, it is fixed with bolts.
[0032] A vibrator 2 is fixedly installed on the lower outer surface of the storage hopper 1. The inner side of the storage hopper 1 is inclined. By using the vibrator 2, the slag powder in the storage hopper 1 can be discharged through the internal vibration of the storage hopper 1.
[0033] The outer surface of one end of the storage hopper 1 is provided with a discharge groove 7, and one end of the docking seat 5 is provided with a rotating wheel 6.

When the conveyor belt moves, it plays a role in cleaning the residual slag on its surface.
[0034] One side of the splicing scraper 11 is provided with a beveled surface 17. The beveled surface 17 is inclined. By using the beveled surface 17, the side of the splicing scraper 11 forms a beveled structure. When the splicing scraper 11 cleans the surface of the scraper 3, the slag powder can be discharged to one side along the beveled surface 17, thereby improving the performance of the splicing scraper 11.
[0035] A self-cleaning mine sweeper, when in use, features a cleaning component 4 to provide a self-cleaning auxiliary function, extending the stability of the mine sweeper during long-term use. During installation, the scraper 3 is inserted into the inner side of the docking seat 5 at both ends, allowing the surface of the scraper 3 to be inserted into the inner side of the cleaning component 4. The splicing scraper strip 11 is attached to one outer surface of the scraper 3, and the upper end of the scraper 3 has an inclined structure. To ensure that the splicing scraper strip 11 can completely clean the surface of the scraper 3 during movement, a movable locking head 13 is provided. During installation of the scraper 3, the movable locking head 13 is moved outwards. After the scraper 3 is installed, push the movable clamp 13 so that the inclined surface of one end of the movable clamp 13 is in contact with the inclined surface of the scraper 3, so that the splicing scraper strip 11 is in contact with the side of the scraper 3. The guide rod 9 and the first screw 8 are used to provide two-point positioning for the movable seat 10, so that the movable seat 10 moves laterally along the guide rod 9 when moving, avoiding the angle change of the movable seat 10 and improving its stability during cleaning. The first screw 8 is used to drive the movable seat 10, so that the splicing scraper strip 11 of the movable seat 10 moves along the surface of the scraper 3, which cleans the slag dust adhering to the surface of the scraper 3.
[0036] By setting up the splicing scraper 11, the use of the cleaning component 4 is optimized when the mine cleaner is used, giving it a multi-adjustable structure and improving its flexibility during use. First, the user can adjust the position of the splicing scraper 11 according to the thickness of the scraper 3 by rotating the second lead screw 14, which drives the adjusting slider 12 through the threaded structure. The adjusting slider 12 drives the splicing scraper 11 to move, thereby meeting the cleaning operation of scrapers 3 with different thicknesses. Second, according to the length of the scraper 3, the corresponding length of the splicing scraper 11 can be selected and installed through the docking buckle 15. After the docking buckle 15 is docked, it is fixed with bolts, thereby meeting the cleaning operation of scrapers 3 with different sizes.
[0037] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
