Technical Field
[0001] The utility model relates to the technical field of mud scrapers, and more specifically, to a scraper structure for self-cleaning the inner wall of a stirred mud. Background Technique
[0002] In engineering construction, mud is a necessary building material. Solid soil and water are stirred in a mud mixer to dissolve the solid soil in water to form mud. However, after the mud is discharged, residual mud often adheres to the inner wall of the mud mixer. If it is not cleaned for a long time, the mud will solidify on the inner wall of the mud mixer. Therefore, it is necessary to clean the inner wall of the mud mixer immediately after the mud is discharged. During the cleaning, a mud scraper is required. The mud scraper is driven by a motor to move around the inner wall of the mud mixer to scrape and clean the mud adhering to the inner wall of the mud mixer.
[0003] Most of the existing mud scrapers for self-cleaning the inner wall of the stirred mud are fixed by simple support arms, and then the scraper is driven by a motor to move. However, most of the lower ends of the inner walls of the existing mud mixers are concave, and there are many types of mud mixers, so the slopes of the concave and convex surfaces at the lower ends of the inner walls are different. Due to the fixation of the support arms, the existing mud scrapers for self-cleaning the inner wall of the stirred mud are difficult to clean the lower ends of the inner walls of various mud mixers, and the scraper is prone to damage during long-term operation. When the scraper is damaged, only the whole scraper structure can be replaced, which is very wasteful. Summary of the Utility Model

Detailed Embodiment
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art of this mud scraper field without making creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.
[0025] As Figure 1 and 2 shown, the present utility model provides a scraper structure for self-cleaning the inner wall of the stirred mud, including a rotating shaft 1 installed at the output end of the motor: four connecting brackets 4 are fixedly arranged on the outer surface of the rotating shaft 1, and a vertical scraper 5 and an inclined scraper 6 are respectively movably arranged on one side and the lower end of the connecting bracket 4.
[0026] In order to be able to adapt to a variety of slurry mixers with different inner wall slopes for scraping and cleaning, an adaptation adjustment device 2 for adjusting the angle of the inclined scraper 6 is provided inside the connecting bracket 4, which is used to automatically adjust the angle of the inclined scraper 6 according to the slope of the lower end of the inner wall of the slurry mixer;
[0027] As Figure 3 shown, the adaptation adjustment device 2 includes a movable groove 21, which is opened inside the connecting bracket 4. A bearing rod 22 is movably arranged inside the movable groove 21. Both ends of the bearing rod 22 penetrate through the movable groove 21 respectively. The outer surfaces of both ends of the bearing rod 22 are movably connected with the through grooves on both sides of the movable groove 21. A movable plate 28 is movably arranged on the outer surface of the bearing rod 22. A hinge seat 27 is fixedly arranged at the lower end of the movable plate 28. The lower end of the movable plate 28 is fixedly connected with the movable end of the hinge seat 27. A chute 24 is opened inside the movable plate 28. The bearing rod 22 is located inside the chute 24. A limiting block 25 is fixedly arranged at the lower end of the chute 24. A sliding rod 23 is fixedly arranged inside the chute 24. The sliding rod 23 penetrates through the inner through groove of the bearing rod 22. The outer surface of the sliding rod 23 is movably connected with the inner through groove of the bearing rod 22. A spring 26 is movably arranged between the bearing rod 22 and the limiting block 25. The spring 26 is located on the outer surface of the sliding rod 23. The movable connection between the movable plate 28 and the second installation frame 36 can be realized through the hinge seat 27. When the utility model is inserted into the slurry mixer, the inclined scraper 6 is placed at the top according to the lower end of the inner wall of the slurry mixer, so as to drive the rotation of the second installation frame 36. When the second installation frame 36 rotates, it drives the movable plate 28 to move. By the sliding of the sliding rod 23 inside the bearing rod 22 and the rotation of the bearing rod 22, the angle change of the second installation frame 36 can be realized. Then, by using the elasticity of the spring 26, the movable plate 28 is pushed downward, and the second installation frame 36 and the inclined scraper 6 can be closely attached to the lower end of the inner wall of the slurry mixer. Therefore, it can adapt to a variety of slurry mixers with different inner wall slopes.
[0028] Furthermore, in order to reduce the replacement of the overall structure of the scraper and reduce waste, a scraper disassembly device 3 for installing or disassembling the vertical scraper 5 and the inclined scraper 6 is provided at one end of the connecting bracket 4;
[0029] As Figure 4As shown in the figure, the scraper disassembly device 3 includes a first mounting frame 31 which is fixedly arranged at one end of the connecting bracket 4. A second mounting frame 36 is hinged to the lower end of the first mounting frame 31. The upper end of the second mounting frame 36 is fixedly connected to the lower end of the hinge seat 27. Slots 32 are respectively formed inside the first mounting frame 31 and the second mounting frame 36. Insert blocks 33 are respectively fixedly arranged on one side of the vertical scraper 5 and the inclined scraper 6. The insert blocks 33 are adapted to the slots 32. Thread grooves 34 are formed inside the insert blocks 33. Bolts 35 penetrate through the upper ends of the first mounting frame 31 and the second mounting frame 36. The thread grooves 34 are in threaded connection with the bolts 35. By inserting the insert blocks 33 into the slots 32, the vertical scraper 5 and the inclined scraper 6 can be respectively installed inside the first mounting frame 31 and the second mounting frame 36. By inserting the bolts 35 into one side of the first mounting frame 31 and the second mounting frame 36 and threading them with the thread grooves 34, the fixation of the vertical scraper 5 and the inclined scraper 6 can be realized. When the two scrapers are worn after long-term use, the bolts 35 can be disassembled and the insert blocks 33 can be pulled out of the slots 32 for replacement, avoiding replacing the overall structure of the scraper and reducing waste.
[0030] The working principle is as follows: When the present utility model is in use, it is inserted into the mud mixer. The adaptive adjustment device 2 can automatically adapt and adjust the angle of the inclined scraper 6 according to the slope of the lower end of the inner wall of the mud mixer. By driving the rotating shaft 1 to rotate with the motor, the effect of cleaning the inner wall of the mud mixer can be achieved. When the vertical scraper 5 and the inclined scraper 6 are worn, the two scrapers are replaced through the scraper disassembly device 3, reducing unnecessary waste. The overall practicability of the present utility model is improved, and it can be applied to mud mixers with various slopes.
[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
