Description

Technical Field

[0001] This utility model relates to the field of mud scraping technology, and more specifically, to a mud scraping mechanism of a mud scraper. Background Technology

[0002] In industries such as wastewater treatment and environmental remediation, sludge scrapers are widely used as crucial equipment in ponds, sedimentation tanks, and wastewater treatment ponds to remove sludge deposited at the bottom. The scraper blade within the scraping mechanism is the core component of the device; its ease of installation and disassembly, as well as the efficiency of softening and cleaning, directly impacts the equipment's operational performance and maintenance costs. However, in existing technologies, the installation and disassembly of the scraper blade is quite inconvenient, and the softening and cleaning operations are also not convenient enough.

[0003] Existing sludge scrapers typically use bolts or slots for fixing the scraper blades. This fixing method makes the installation and removal of the scraper blades relatively complex, requiring precise operation with tools. Especially in actual operation, the use of tools, tightening and aligning bolts require operators to spend a lot of time, increasing the difficulty of manual operation and the downtime of the production line.

[0004] Before cleaning sludge, scrapers typically need to be softened to reduce sludge adhesion and improve cleaning efficiency. However, existing scraper softening technologies are relatively primitive, with complex and time-consuming procedures. They usually require manual addition of softening agents or high-temperature heating, which are not only inefficient but also require significant operating space and manpower. Utility Model Content

A rolling shaft is installed on the installation box and is located at the top end of the spraying assembly. The plate clamping mechanism includes a clamping pipe and a clamping rod. A prying groove is formed on the side wall of the clamping rod. A longitudinal sliding sleeve is slidably installed on the outer wall of the clamping pipe. A rotating plate is rotatably installed on the side wall of the clamping pipe, and a pressing block and a prying block are installed at both ends of the rotating plate. The longitudinal sliding sleeve presses against the rotating plate and the pressing block, causing the prying block to extend into or move away from the prying groove.

[0007] The present invention is further configured such that the snap-fit ​​auxiliary mechanism includes an outer rotating frame and a double-layer clamping ring, wherein the outer rotating frame is rotatably mounted on the outer wall of the snap-fit ​​tube, the double-layer clamping ring is fixedly mounted on the outer wall of the snap-fit ​​tube, a sandwich plate is installed at the top end of the outer rotating frame, one end of the sandwich plate extends into the double-layer clamping ring to cooperate with the rotatable limiting setting, a bidirectional spring rod is installed on the sandwich plate, and a positioning hole is opened on the double-layer clamping ring. The bidirectional spring rod can extend into different positioning holes to make the outer rotating frame rotate stably. The inner wall of the outer rotating frame is threadedly connected to the longitudinal sliding sleeve, and the rotation of the outer rotating frame drives the longitudinal sliding sleeve to move longitudinally.

[0008] The present invention is further configured such that a counterweight is installed at the top end of the base plate, and the water pump and water tank are installed at the top end of the counterweight. The counterweight is installed on the top of the base plate, which increases the overall weight and stability, provides an installation platform for the water tank and water pump, and optimizes the space layout.

[0009] The present invention is further configured such that a support plate is installed on the mounting box, and the clamping pipe is fixedly installed on the support plate. The support plate is installed on the mounting box to provide an installation platform for the clamping pipe, support the clamping system, and ensure stable operation of the scraper.

[0010] The present invention is further configured such that one end of the locking rod is connected to the scraper, and the other end of the locking rod extends through the support plate and engages with the locking tube. One end of the locking rod is connected to the scraper, and the other end extends into the locking tube to engage. A pry groove is provided on the side wall to achieve a locking engagement with the pry block.

[0011] The present invention is further configured such that a screw lifting assembly is installed on the top side of the base plate, a lifting plate is installed on the screw lifting assembly, a mounting box is installed on the lifting plate, and the screw lifting assembly is installed on the top side of the base plate, so as to realize precise height adjustment, provide vertical movement control, and adapt to different working environments.

[0012] The present invention is further provided that a connecting plate is installed at the bottom end of the side wall of the clamping tube, and the connecting plate is fixedly installed on the support plate.

[0013] The present invention is further provided that bottom wheels are installed around the bottom of the base plate, which provides convenience for movement, enabling the device to flexibly move to a different working position and improve work efficiency.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a sludge scraping mechanism for a sludge scraper, which has the following beneficial effects: This invention features a spraying mechanism that, through the combined design of a water tank, a water pump, connecting hoses, and spraying components, effectively cleans the surface of the scraped mud while softening it. The water pump delivers water from the tank to the spraying components via the connecting hoses, ensuring a stable water supply. Notably, the roller shaft is positioned at the top of the spraying components, allowing cleaning and compaction to occur simultaneously. This not only improves cleaning efficiency but also makes the mud easier to scrape off, significantly enhancing the overall scraping effect. This design reduces operational steps and increases work efficiency.

[0015] This utility model features a plate clamping mechanism that uses a clamping tube and a clamping rod in combination. Combined with the rocker principle of the rotating plate, it enables the rapid installation and disassembly of the scraper. The pry groove on the side wall of the clamping rod and the pry block on the rotating plate form a locking mechanism. The locking state is controlled by the pressure of the longitudinal sleeve on the rotating plate, ensuring a stable connection of the scraper during operation. At the same time, it facilitates replacement and maintenance, improving the practicality and maintenance efficiency of the equipment.

[0016] This utility model is equipped with a snap-fit ​​auxiliary mechanism. Through the coordinated work of the outer rotating frame, double-layer clamping ring, sandwich plate, and bidirectional spring rod, the snap-fit ​​auxiliary mechanism provides precise and reliable control for the plate snap-fit ​​mechanism. The threaded connection between the outer rotating frame and the longitudinal sleeve converts the rotational motion into longitudinal motion. The limiting design of the sandwich plate and the double-layer clamping ring prevents excessive rotation. The cooperation between the bidirectional spring rod and the positioning hole provides multiple positioning positions, making the locking and unlocking operations more precise and controllable, improving the convenience and safety of operation, extending the service life of the device, and enhancing the reliability and adaptability of the entire sludge scraping mechanism.

[0022] Please see Figures 1-5A sludge scraping mechanism for a sludge scraper includes a base plate 1, a scraper 2, a spraying mechanism, a plate clamping mechanism, and a clamping auxiliary mechanism. The spraying mechanism includes a water tank 3 and a mounting box 4. A water pump 5 is mounted on the side of the water tank 3, with one end of the pump extending into the water tank 3 and the other end of the pump being connected to a connecting hose 6. A spraying assembly 7 is installed inside the mounting box 4, with the other end of the connecting hose 6 connected to the spraying assembly 7. A rolling shaft 8 is mounted on the mounting box 4. The rolling shaft 8 is located at the top end of the spray assembly 7. The plate clamping mechanism includes a clamping tube 9 and a clamping rod 10. A pry groove 11 is provided on the side wall of the clamping rod 10. A longitudinal sliding sleeve 12 is longitudinally slidably installed on the outer wall of the clamping tube 9. A rotating plate 13 is rotatably installed on the side wall of the clamping tube 9. A pressing block 14 and a prying block 15 are installed at both ends of the rotating plate 13. The longitudinal sliding sleeve 12 presses against the rotating plate 13 and the pressing block 14, so that the prying block 15 extends into or away from the pry groove 11.

[0023] In this embodiment, the spraying mechanism performs cleaning or mud-removing functions. During operation, the water pump 5 draws water from the water tank 3 and delivers it to the spraying assembly 7 inside the installation box 4 via the connecting hose 6. The spraying assembly 7 sprays water onto the surface to be cleaned, while the top roller 8 performs rolling treatment on the surface after spraying, enhancing the cleaning effect and allowing cleaning and compaction to occur simultaneously, thus improving cleaning efficiency. The plate locking mechanism achieves the installation and removal of the scraper 2 through the cooperation of the locking rod 10 and the locking pipe 9. The pry groove 11 on the side wall of the locking rod 10 and the pry block 15 on the rotating plate 13 form a locking mechanism. When the longitudinal sleeve 12 presses against the rotating plate 13, the pry block 15 at one end of the rotating plate 13 extends into the pry groove 11 to complete the locking. When the longitudinal sleeve 12 presses against the pressing block 14, the pry block 15 moves away from the pry groove 11 to complete the unlocking, ensuring the stability of the scraper 2 during operation and facilitating the replacement of different scrapers 2.

[0024] The snap-fit ​​auxiliary mechanism includes an outer rotating frame 16 and a double-layer clamping ring 17. The outer rotating frame 16 is rotatably mounted on the outer wall of the snap-fit ​​tube 9, and the double-layer clamping ring 17 is fixedly mounted on the outer wall of the snap-fit ​​tube 9. A sandwich plate 18 is installed at the top end of the outer rotating frame 16. One end of the sandwich plate 18 extends into the double-layer clamping ring 17 to cooperate with the rotatable limit setting. A bidirectional spring rod 19 is installed on the sandwich plate 18, and a positioning hole 20 is opened on the double-layer clamping ring 17. The bidirectional spring rod 19 can extend into different positioning holes 20 to make the outer rotating frame 16 rotate stably. The inner wall of the outer rotating frame 16 is threadedly connected to the longitudinal sliding sleeve 12. The rotation of the outer rotating frame 16 drives the longitudinal sliding sleeve 12 to move longitudinally.

[0025] In this embodiment, the locking auxiliary mechanism controls the up-and-down movement of the longitudinal sleeve 12 by rotating the outer rotating frame 16. The outer rotating frame 16 is mounted on the outer wall of the locking tube 9 with a limit rotation, and its inner wall is threadedly connected to the longitudinal sleeve 12. When the outer rotating frame 16 is rotated, the interlayer plate 18 extends into the double-layer clamping ring 17 to limit rotation, and the bidirectional spring rod 19 extends into the positioning hole 20 to ensure rotation accuracy. The rotation of the outer rotating frame 16 drives the longitudinal sleeve 12 to move longitudinally, thereby controlling the locking state and ensuring the accuracy and reliability of the locking operation.

[0026] Please see Figures 1-5 As a supplementary embodiment of the sludge scraping mechanism of a sludge scraper, which includes a spraying mechanism, a plate clamping mechanism, and a clamping auxiliary mechanism: A counterweight 21 is installed at the top end of the base plate 1. A water pump 5 and a water tank 3 are installed at the top end of the counterweight 21. A support plate 22 is installed on the mounting box 4, and a clamping pipe 9 is fixedly installed on the support plate 22. One end of the clamping rod 10 is connected to the scraper 2, and the other end of the clamping rod 10 extends through the support plate 22 and engages with the clamping pipe 9. A screw lifting assembly 23 is installed on the side of the top end of the base plate 1, and a lifting plate 24 is installed on the screw lifting assembly 23. The mounting box 4 is installed on the lifting plate 24. A connecting plate 25 is installed at the bottom end of the side wall of the clamping pipe 9, and the connecting plate 25 is fixedly installed on the support plate 22. Bottom wheels 26 are installed around the bottom end of the base plate 1.

[0027] More specifically, the entire sludge scraper operation process begins with the bottom wheel 26 moving to the working position. Then, the height of the mounting box 4 is adjusted using the screw lifting assembly 23 to position the scraper 2. The outer rotating frame 16 is rotated through the locking auxiliary mechanism, which drives the longitudinal sleeve 12 to move, locking the plate body locking mechanism and firmly connecting the scraper 2 to the support structure. The water pump 5 is started, and water is transported from the water tank 3 to the spray assembly 7 through the connecting hose 6 to spray and clean the surface. At the same time, the roller shaft 8 compacts the surface. The scraper 2 moves with the device to perform sludge scraping operations. The counterweight 21 ensures overall stability. After the operation is completed, the outer rotating frame 16 is rotated in the opposite direction to release the locking mechanism, making it easy to replace the scraper 2 or perform maintenance. The entire device efficiently completes the sludge scraping and cleaning work through the combination of spray cleaning, rolling, and scraping.

[0028] In summary, when the overall equipment is in use or running: when the spraying mechanism is required to run, the spraying mechanism realizes the cleaning or mud-removing function. During operation, the water pump 5 draws water from the water tank 3 and delivers the water to the spraying component 7 in the installation box 4 through the connecting hose 6. The spraying component 7 sprays water onto the surface to be cleaned, while the roller 8 on the top performs a rolling treatment on the surface after spraying, enhancing the cleaning effect and allowing cleaning and compaction to be carried out simultaneously, thus improving the cleaning efficiency.

[0029] When the plate clamping mechanism is in operation, the plate clamping mechanism realizes the installation and removal of the scraper 2 through the cooperation of the clamping rod 10 and the clamping tube 9. The pry groove 11 on the side wall of the clamping rod 10 and the pry block 15 on the rotating plate 13 form a locking mechanism. When the longitudinal sleeve 12 presses against the rotating plate 13, the pry block 15 at one end of the rotating plate 13 extends into the pry groove 11 to complete the locking. When the longitudinal sleeve 12 presses against the pressing block 14, the pry block 15 moves away from the pry groove 11 to complete the unlocking, which ensures the stability of the scraper 2 in the working process and facilitates the replacement of different scrapers 2.

[0030] When the locking auxiliary mechanism is in operation, the locking auxiliary mechanism controls the vertical movement of the longitudinal sleeve 12 by rotating the outer rotating frame 16. The outer rotating frame 16 is mounted on the outer wall of the locking tube 9 with a limit rotation, and its inner wall is threadedly connected to the longitudinal sleeve 12. When the outer rotating frame 16 is rotated, the sandwich plate 18 extends into the double-layer clamping ring 17 to limit rotation, and the bidirectional spring rod 19 extends into the positioning hole 20 to ensure rotation accuracy. The rotation of the outer rotating frame 16 drives the longitudinal sleeve 12 to move longitudinally, thereby controlling the locking state and ensuring the accuracy and reliability of the locking operation.

[0031] The entire sludge scraper operation process begins with the bottom wheel 26 moving to the working position. Then, the height of the mounting box 4 is adjusted using the screw lifting assembly 23 to position the scraper 2. The outer frame 16 is rotated through the locking auxiliary mechanism, which drives the longitudinal sleeve 12 to move, locking the plate body locking mechanism and firmly connecting the scraper 2 to the support structure. The water pump 5 is started, and water is transported from the water tank 3 to the spray assembly 7 through the connecting hose 6 to spray and clean the surface. At the same time, the roller shaft 8 compacts the surface. The scraper 2 moves with the device to perform sludge scraping operations. The counterweight 21 ensures overall stability. After the operation is completed, the outer frame 16 is rotated in the opposite direction to release the locking mechanism, making it easy to replace the scraper 2 or perform maintenance. The entire device efficiently completes the sludge scraping and cleaning work through the combination of spray cleaning, rolling, and scraping.
