Description

Technical Field

[0001] This utility model relates to the technical field of sludge treatment equipment, specifically a sludge scraper for cleaning sewage tanks. Background Technology

[0002] Patent publication number CN216297420U discloses a sludge scraping mechanism for cleaning the inner wall of a sewage treatment tank. It includes two sets of machine bodies and casters mounted on the bottom of the machine bodies. A mounting plate is fixedly attached to the top of the machine bodies, a support rod is fixedly attached between the two mounting plates, and a horizontal plate is fixedly attached between the two mounting plates. The horizontal plate is located below the support rod, and a movable block is movably sleeved on the outer side of the support rod. The movable block has a cavity inside. This sludge scraping mechanism for cleaning the inner wall of a sewage treatment tank allows the operator to control the height of the scraper by controlling an electric push rod through the cooperation between the top block and the protrusion. Simultaneously, through the cooperation between the top rod and the fixed plate, after the operator starts the motor, the scraper can quickly scrape away the sludge by swinging back and forth, preventing sludge accumulation, increasing scraping efficiency, and facilitating operation.

[0003] Stubborn stains are often difficult to remove from sewage tanks with just one scraping, and usually require repeated scraping. However, repeated scraping inevitably lengthens the scraper's travel path, which not only reduces work efficiency but also increases costs. Utility Model Content

[0004] The purpose of this invention is to provide a sludge scraper for cleaning sewage tanks.

[0005] The technical problem solved by this utility model is that the increased reciprocating brush path for removing stubborn stains reduces work efficiency and thus increases costs.

[0006] This utility model can be achieved through the following technical solution: it includes a body, on which a lifting frame capable of moving up and down in the vertical direction is installed, a guide plate is fixedly installed on the lifting frame, a moving block is slidably installed through the guide plate, a slider capable of reciprocating left and right is slidably installed through the bottom of the moving block, a scraper is fixedly installed at the bottom of the slider, and a driving component for driving the moving block to move left and right is installed on the lifting frame.

[0007] A further technical improvement of this utility model is that the structure that causes the slider to move back and forth includes a rack plate fixedly installed on the lifting frame, a gear that meshes with the rack plate and is rotatably installed through the slider, a turntable is fixedly installed at the end of the gear shaft away from the rack plate, a fixing rod is fixedly installed at a position off-center on one side of the turntable, a sliding groove is opened on the side of the slider near the turntable, and the fixing rod and the sliding groove are slidably connected through the groove.

[0008] Furthermore, the drive assembly includes a threaded rod that is threaded through the moving block, with both ends of the threaded rod rotatably connected to both sides of the lifting frame.

[0009] Furthermore, a sliding rod is slidably installed through the top of the scraper, with both ends of the sliding rod fixedly connected to the two sides of the slider. Springs sleeved on the outer periphery of the sliding rod are respectively abutted between the two sides of the scraper and the two sides of the slider.

[0010] Furthermore, the structure that enables the lifting frame to move vertically up and down includes an electric telescopic rod fixedly installed on the top of the machine body, the output end of which is fixedly connected to the lifting frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this application, during the process of the moving block driving the scraper to move along the inner wall of the sewage tank, the scraper will move back and forth within a certain range at the bottom of the moving block, thereby repeatedly scraping the inner wall of the sewage tank that it comes into contact with along the travel path, so as to reduce the distance the scraper travels repeatedly and improve work efficiency.

[0018] 7. To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] Please see Figure 1-3As shown, this embodiment provides a sludge scraper for cleaning sewage tanks, including a body 1. An electric telescopic rod 2 is fixedly installed on the top of the body 1. A lifting frame 3 is fixedly installed at the output end of the electric telescopic rod 2. A threaded rod 4 is rotatably installed through the lifting frame 3. A drive motor for driving the threaded rod 4 to rotate is installed on the lifting frame 3. A guide plate 5 is fixedly installed on the lifting frame 3. A moving block 6 is slidably installed through the guide plate 5. The moving block 6 is threadedly connected to the threaded rod 4. A slider 7 is slidably installed through the bottom of the moving block 6. A scraper 8 is fixedly installed at the bottom of the slider 7.

[0020] The telescopic movement of the electric telescopic rod 2 will drive the lifting frame 3 to move up and down synchronously in the vertical direction. When the threaded rod 4 is rotated clockwise, it will drive the moving block 6 to move along the guide plate 5 to one side of the lifting frame 3, and vice versa. The moving block 6 will drive the scraper 8 to move synchronously, so that the scraper 8 can scrape the sludge on the inner wall of the sewage tank.

[0021] A rack plate 9 is fixedly installed on the lifting frame 3. A gear 10 that meshes with the rack plate 9 is rotatably installed through the slider 7. A turntable 11 is fixedly installed at the end of the gear 10 shaft away from the rack plate 9. A fixing rod 12 is fixedly installed at a position off-center on one side of the turntable 11. A slide groove 13 is opened on the side of the slider 7 near the turntable 11. The fixing rod 12 and the slide groove 13 are slidably connected through the slide. A slide rod 14 is slidably installed through the top of the scraper 8. The two ends of the slide rod 14 are fixedly connected to the two sides of the slider 7 respectively. Springs 15 sleeved on the outer periphery of the slide rod 14 are abutted between the two sides of the scraper 8 and the two sides of the slider 7 respectively.

[0022] As the moving block 6 moves, it drives the gear 10 to roll on the rack plate 9, thereby causing the shaft of the gear 10 to rotate and drive the turntable 11 to rotate synchronously. The rotating turntable 11 drives the slider 7 to slide back and forth at the bottom of the moving block 6 through the fixed rod 12. During this process, the fixed rod 12 slides in the groove 13 to correct the positional relationship between the fixed rod 12 and the slider 7. At the same time, the slider 7 slides back and forth, which drives the scraper 8 to move synchronously, thereby causing the scraper 8 to alternately squeeze the springs 15 on both sides. When the springs 15 are squeezed, their elasticity will have a certain reaction force on the scraper 8. Therefore, both sides of the scraper 8 are under force, which allows the scraper 8 to maintain a certain fixed state and not easily shake, thus ensuring the stability of the scraper 8 when scraping sludge.

[0023] In use, the machine body 1 is moved onto the sewage tank to be cleaned. Then, the electric telescopic rod 2 drives the lifting frame 3 to move up and down vertically until the scraper 8 is adjusted vertically to be in complete contact with the inner wall of the sewage tank. Then, the threaded rod 4 drives the moving block 6 to move horizontally along the guide plate 5, thereby causing the scraper 8, which is in contact with the inner wall of the sewage tank, to scrape off the sludge on the inner wall. During the movement of the moving block 6, the scraper 8 will move back and forth left and right at the bottom of the moving block 6, thereby repeatedly scraping the sludge on the path of the inner wall of the sewage tank to loosen the adhesion between the sludge and the inner wall of the sewage tank, and more thoroughly remove the stubborn stains on the inner wall of the sewage tank, thus improving the cleaning effect.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
