Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water treatment, in particular to an automatic regulating mud scraping device for a mud discharge vehicle. Background Art
[0002] A mud truck is a vehicle used to clean and transport mud or other solid waste. The mud truck extracts the sludge from the bottom of the pool through a mud pump, but due to the uneven sedimentation of the sludge at the bottom, the extracted mud water has a low solid content, which will waste a lot of water resources. The installation of a scraper can gather the sludge at the bottom of the pool and increase the solid content of the extracted mud water. However, after the fixed scraper is cleaned, the mud truck can easily scrape the sludge at the bottom of the sedimentation tank back on the return trip, resulting in an unsatisfactory cleaning effect. Utility Model Content
[0003] In order to solve the problems in the above-mentioned background technology, the utility model provides an automatically adjustable mud scraping device for a mud discharge vehicle, which can improve the solid content of the extracted mud water while preventing the mud discharge vehicle from scraping back the sludge when returning, thereby improving the cleaning efficiency, and the equipment is simple and low in cost.
[0004] The solution adopted by the utility model to solve the technical problem is: an automatically adjustable mud scraping mechanism for a mud discharge vehicle, comprising a mud discharge vehicle arranged in a water pool and a mud scraping device installed on the mud discharge vehicle, the mud scraping device is rotatably connected to the bottom of the mud discharge vehicle, and guide devices for pushing the mud scraping device to rotate and switch the working state are provided at both ends of the water pool bottom corresponding to the moving direction of the mud discharge vehicle.
[0005] By adopting the above technical solution, the mud removal vehicle can scrape mud in one direction, thereby improving the cleaning effect.

[0007] By adopting the above technical solution, the mud scraper device can rotate at the bottom of the mud discharge vehicle.
[0008] Furthermore, the guiding device includes a downward pressure rod arranged at the starting end of the pool scraper and a lifting rod arranged at the end of the pool scraper; the downward pressure rod causes the scraper to rotate toward the bottom and contact the bottom of the pool by pressing down the scraper device; the lifting rod causes the scraper to rotate toward the top and away from the bottom of the pool by lifting the scraper device.
[0009] By adopting the above technical solution, the rotation of the scraper device can be achieved without too much impact force, which can reduce equipment wear and extend the service life of the equipment.
[0010] Furthermore, the scraper device is equipped with an adjusting piece, which is arranged between the rotating plate and the scraper, and extends to the outside of the scraper device; the pressing rod presses the adjusting piece to the bottom of the pool, so that the scraper rotates toward the bottom and contacts the bottom of the pool; the lifting rod pushes the adjusting piece to the top of the pool through the guiding slope, so that the scraper rotates toward the top and away from the bottom of the pool.
[0011] By adopting the above technical solution, the downward pressure rod and the lifting rod are used to apply forces in different directions to the adjusting member, thereby changing the movement state of the mud scraper device without affecting the forward or backward movement of the mud discharge vehicle.
[0012] Furthermore, the adjusting member includes a fixed rod and a rotating wheel. The fixed rod is located between the rotating plate and the scraper and protrudes toward the outside of the scraper device. The rotating wheel is located on the side of the fixed rod away from the scraper device and is circled around the outer periphery of the fixed rod. The pressing rod and the lifting rod apply pressure to the rotating wheel to guide the scraper device to automatically adjust the rotation direction.
[0013] By adopting the above technical solution, the rotating wheel can move relative to the surface of the lower pressure rod or the upper lifting rod, and then the force drives the mud scraper device to rotate upward or downward.
[0014] Furthermore, the guide device includes a top impact head and a bottom impact head; the top impact head causes the scraper to rotate toward the bottom and contact the bottom of the pool by impacting the rotating plate; the bottom impact head causes the scraper to rotate toward the top and away from the bottom of the pool by impacting the rotating plate.
[0015] By adopting the above technical solution, the installation of the guide device is facilitated.
[0016] Furthermore, the top impact head and the bottom impact head are both provided with an impact wheel for impacting the mud scraping device; the top impact head impacts the top of the rotating plate through the impact wheel, thereby causing the mud scraping device to rotate toward the bottom of the pool and contact the bottom of the pool; the bottom impact head impacts the bottom of the rotating plate through the impact wheel, thereby causing the mud scraping device to rotate toward the top of the pool and away from the bottom of the pool.
[0017] By adopting the above technical solution, the top impact head is prevented from hitting the surface of the mud scraper device or the top impact head is prevented from damaging the surface of the mud scraper device.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.
[0033] like Figure 1 and Figure 2 As shown, an automatic adjustment scraping mechanism for a mud discharge vehicle 1 includes a mud discharge vehicle 1 arranged in a water pool and a scraping device 2 installed on the mud discharge vehicle 1. The scraping device 2 is rotatably connected to the bottom of the mud discharge vehicle 1. The two ends of the water pool bottom corresponding to the moving direction of the mud discharge vehicle 1 are provided with guide devices 4 for pushing the scraping device 2 to rotate and switch the working state. When the mud discharge vehicle 1 scrapes mud from the beginning to the end of the water pool, the scraping device 2 is in a lowered state, which can pile up the uneven mud at the bottom of the water pool and increase the solid content of the mud discharge water. When the mud discharge vehicle 1 reaches the end of the water pool, the guide device 4 at the end of the water pool applies an upward force to the scraping device 2, causing the scraping device 2 to rotate upward away from the bottom of the water pool. At this time, when the mud discharge vehicle 1 returns, the scraping device 2 does not contact the bottom of the water pool, and does not cause sludge back scraping, thereby improving the efficiency of sludge cleaning. When the mud discharge vehicle 1 returns to the beginning of the pool, the guide device 4 at the beginning of the pool applies downward pressure to the mud scraper device 2, causing it to move down and contact the bottom of the pool. When the mud discharge vehicle 1 moves from the beginning of the pool to the end again, it can scrape the mud again. This cycle is repeated to achieve automatic adjustment of the mud scraper device 2.
[0034] like Figure 1 and Figure 4As shown, the scraper device 2 of this embodiment includes a scraper plate 21 at the bottom and a rotating plate 22. The rotating plate 22 is "L" shaped and one end of the scraper plate 21 is fixed together by screws. The rotating plate 22 is rotatably connected to the mud discharge vehicle 1 at the corner through a rotating shaft. When the scraper device 2 contacts the bottom of the pool to scrape the mud, the rotating plate 22 presses against the scraper plate 21 and applies downward pressure to it, so that the scraper plate 21 is placed obliquely on the bottom of the pool. When the mud discharge vehicle 1 scrapes the mud along the way, the scraper plate 21 can gather the mud at the bottom of the pool to facilitate mud discharge. Since the rotating plate 22 is made of metal and has a large weight, it can prevent the scraper device 2 from turning upward due to mud accumulation during the scraping operation, affecting the operation of the mud discharge vehicle 1. When the mud discharge vehicle 1 returns and the scraper device 2 is away from the bottom of the pool, the scraper plate 21 is placed horizontally on the upper end of the mud. At this time, the rotating plate 22 provides an upward force for the scraper plate 21 to prevent the scraper plate 21 from falling and contacting the mud, and prevent the mud from being scraped back.
[0035] like Figure 2 As shown, the guide device 4 of this embodiment includes a pressing rod 44 arranged at the starting end of the pool scraper and a lifting rod 45 arranged at the end of the pool scraper; the lower end of the pressing rod 44 stands vertically on the bottom of the pool, and the upper end thereof gradually extends upward from the side close to the starting end of the pool to the side of the end of the pool; the lower end of the lifting rod 45 is vertically adjacent to the bottom of the pool, and the upper end thereof gradually extends downward from the side close to the end of the pool to the side of the starting end of the pool, and the pressing rod 44 presses down the scraper device 2 to rotate the scraper 21 toward the bottom and contact the bottom of the pool; the lifting rod 45 lifts up the scraper device 2 to rotate the scraper 21 toward the top away from the bottom of the pool.
[0036] When the mud discharge vehicle 1 moves toward the end, the lifting rod 45 at the end of the pool contacts the rotating wheel 32 and is located at the bottom of the rotating wheel 32. As the mud discharge vehicle 1 runs, the lifting rod 45 conflicts with the rotating wheel 32. Since the upper end of the lifting rod 45 gradually extends upward toward the end of the pool, as the mud discharge vehicle 1 runs to the end of the pool, the upward force it applies to the rotating wheel 32 gradually increases until the scraper 21 rotates toward the top of the pool and away from the bottom of the pool; when the mud discharge vehicle 1 returns to the starting end of the pool, the pressing rod 44 contacts the rotating wheel 32 and is located at the top of the rotating wheel 32. Since the pressing rod 44 extends upward toward the starting end of the pool, as the mud discharge vehicle 1 moves toward the pool, the pressing rod 44 conflicts with the rotating wheel 32, and the downward force applied by the pressing rod 44 to the rotating wheel 32 gradually increases until the scraper 21 rotates toward the bottom of the pool and contacts the bottom of the pool. In addition, due to the relative movement of the pressing rod 44, the lifting rod 45 and the rotating wheel 32, the force of the two gradually increases, which can prevent the equipment from being damaged due to sudden excessive force, extend the service life of the equipment and reduce production costs.
[0037] like Figure 3As shown, the scraper device 2 is equipped with an adjustment member 3, which is arranged between the rotating plate 22 and the scraper 21, and extends to the outside of the scraper device 2; the lower pressure rod 44 presses the adjustment member 3 to the bottom of the pool, so that the scraper 21 rotates toward the bottom and contacts the bottom of the pool; the lifting rod 45 pushes the adjustment member 3 to the top of the pool, so that the scraper 21 rotates toward the top away from the bottom of the pool. The adjustment member 3 includes a fixed rod 31 and a rotating wheel 32, the fixed rod 31 is located between the rotating plate 22 and the scraper 21 and protrudes toward the outside of the scraper device 2, the rotating wheel 32 is located on the side of the fixed rod 31 away from the scraper device 2 and is encircled by the outer periphery of the fixed rod 31, and the lifting rod 45 and the lower pressure rod 44 apply pressure to the rotating wheel 32, thereby guiding the scraper device 2 to automatically adjust the rotation direction.
[0038] like Figure 5 As shown, another implementation of this embodiment is that the guide device 4 includes a top impact head 41 and a bottom impact head 42; specifically, as Figure 6 and Figure 7 As shown, the top impact head 41 and the bottom impact head 42 are both provided with an impact wheel 43 for impacting the scraper device 2. The top impact head 41 impacts the rotating plate 22 through the impact wheel 43 to make the scraper 21 rotate toward the bottom and contact the bottom of the pool; the bottom impact head 42 impacts the rotating plate 22 through the impact wheel 43 to make the scraper 21 rotate toward the top and away from the bottom of the pool. When the mud discharge vehicle 1 moves toward the end, the bottom impact head 42 at the end of the pool protrudes from the bottom of the pool to the top and contacts the bottom of the rotating plate 22. As the mud discharge vehicle 1 runs, the impact wheel 43 on the bottom impact head 42 conflicts with the rotating plate 22, and the impact wheel 43 gradually applies an upward force to the rotating plate 22 until the scraper 21 rotates toward the top of the pool and away from the bottom of the pool; when the mud discharge vehicle 1 returns to the starting end of the pool, the top impact head 41 at the starting end of the pool extends outward from the side of the pool, is placed horizontally in the pool and contacts the rotating plate 22, and is located at the top of the rotating plate 22. As the mud discharge vehicle 1 runs, the impact wheel 43 on the top impact head 41 conflicts with the rotating plate 22, and the impact wheel 43 gradually applies a downward force to the rotating wheel 32 until the scraper 21 rotates toward the bottom of the pool and contacts the bottom of the pool.
[0039] The scraper 21 of the utility model is made of rubber material, which has high wear resistance, corrosion resistance, anti-aging performance and shock absorption performance. The use of rubber material can extend the service life of the equipment, and there is no need to frequently replace the scraper 21, which reduces the workload of the staff and reduces production costs. The mud discharge vehicle 1 is provided with a prompt flash light. When the mud discharge vehicle 1 moves forward, the prompt flash light lights up, which is convenient for the staff to observe the movement state of the mud discharge vehicle 1. The above embodiments are only preferred implementation methods of the utility model, and cannot be used to limit the protection scope of the utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model belong to the protection scope of the utility model.
