A sludge scraper generally consists of a drive assembly, a scraping assembly, and a skimming assembly.

[0003] However, existing sludge scrapers often lack the function of quick installation and disassembly. Installing and disassembling the scraper blades is time-consuming and laborious, and it is inconvenient to clean and replace the scraper. In addition, existing sludge scrapers often lack the function of making the scraper blades fit tightly against the bottom of the sedimentation tank, which reduces the cleaning effect. Therefore, there is an urgent need for a sludge scraper component to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a sludge scraper assembly to solve the problems mentioned in the background art, which are that existing sludge scrapers often do not have the function of quick installation and disassembly, making it inconvenient to clean and replace the sludge scraper, and existing sludge scrapers often do not have the function of making the scraper blades fit tightly against the bottom of the sedimentation tank, thus reducing the cleaning effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sludge scraper assembly, comprising a drive shaft, scraper arms, a pull rod, a pressing structure, an mounting structure, and a scraper blade. Scraper arms are fixedly connected to both sides of the drive shaft. One end of a pull rod is fixedly connected to the top of the scraper arms, and the other end of the pull rod is fixedly connected to the outer wall of the drive shaft. The pressing structure includes a support rod one, which is slidably connected to a support rod two. The mounting structure includes a fixed seat one and a fixed seat two. The bottom of the support rod two is fixedly connected to the fixed seat one, and an insert rod is fixedly connected to the top of the fixed seat two. An insert rod is inserted into the bottom of the fixed seat one. Both the fixed seat one and the fixed seat two are secured with clamps. The bottom of the fixed seat two is fixedly connected to the scraper blade.

[0006] Preferably, the first support rod has sliding grooves at both its front and rear ends, and the second support rod has sliding rods fixedly connected to both its front and rear sides, with the sliding rods of the second support rod slidably connected to the sliding grooves of the first support rod.

[0007] Preferably, a spring is fitted inside the first support rod, with one end of the spring abutting against the inner wall of the first support rod and the other end of the spring abutting against the outer wall of the second support rod.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a sludge scraper assembly, including a drive shaft 1, scraper arms 2, a pull rod 3, a pressing structure 4, a mounting structure 5, and a scraper plate 6. Scraper arms 2 are fixedly connected to both sides of the drive shaft 1. One end of the pull rod 3 is fixedly connected to the top of the scraper arms 2, and the other end of the pull rod 3 is fixedly connected to the outer wall of the drive shaft 1. The pressing structure 4 includes a first support rod 41, which is slidably connected to a second support rod 42. The mounting structure 5 includes a first fixing seat 51 and a second fixing seat 54, with the bottom of the second support rod 42 fixedly connected to the first fixing seat 51. 1. The top of the fixed base 2 54 is fixedly connected to the plug rod 56, and the bottom of the fixed base 1 51 is inserted with the plug rod 56. The fixed base 1 51 and the clamp 58 are both clamped with the clamp 58. The bottom of the fixed base 2 54 is fixedly connected to the scraper 6. The scraper 6 can be quickly installed and removed through the installation structure 5, which improves the installation efficiency of the scraper 6 and facilitates the cleaning of the scraper 6. The downward pressing structure 4 can make the scraper adapt to sedimentation tanks of different depths, which improves its applicability. It can also keep the scraper 6 against the bottom of the sedimentation tank, which improves the cleaning effect.

[0023] Furthermore, both ends of the first support rod 41 are provided with sliding grooves, and both sides of the second support rod 42 are fixedly connected with sliding rods. The sliding rods of the second support rod 42 are slidably connected to the sliding grooves of the first support rod 41. The sliding rods play a limiting role, which can prevent the second support rod 42 from detaching from the first support rod 41 and prevent the second support rod 42 from rotating. It also makes the sliding of the second support rod 42 more stable and improves the stability during movement.

[0024] Furthermore, a spring 43 is fitted inside the support rod 41. One end of the spring 43 abuts against the inner wall of the support rod 41, and the other end of the spring 43 abuts against the outer wall of the support rod 42. The scraper 6 drives the support rod 42 to move upward, causing the spring 43 to be compressed under pressure, which causes the support rod 42 to contract and move into the support rod 41. The elastic force of the spring 43 pushes the support rod 42 downward, so that the scraper 6 always abuts against the bottom surface of the sedimentation tank.

[0025] Furthermore, a slot 52 is provided at the bottom of the fixed base 51, and limiting plates 57 are fixedly connected to both sides of the insertion rod 56. The insertion rod 56 and the limiting plate 57 are inserted into the slot 52. The insertion rod 56 and the limiting plate 57 are inserted into the slot 52, and the limiting plate 57 limits the scraper 6 to prevent the scraper 6 from rotating.

[0026] Furthermore, the bottom outer wall of the fixed base 51 is fixedly connected to the fixed plate 53, and the top outer wall of the fixed base 54 is fixedly connected to the fixed plate 55. Both the fixed plate 53 and the fixed plate 55 are clamped with clamps 58, and the two clamps 58 are clamped on the fixed plate 53 and the fixed plate 55, and the positions of the fixed plate 53 and the fixed plate 55 are fixed by the clamps 58.

[0027] Furthermore, the inner wall of the clamp 58 is fixedly connected to the rubber pad 59, and the inner wall of the rubber pad 59 is provided with an uneven pattern. The inner wall of the rubber pad 59 is in contact with the outer wall of the first fixing plate 53 and the second fixing plate 55. The rubber pad 59 can increase the friction between the inner wall of the clamp 58 and the first fixing plate 53 and the second fixing plate 55. The uneven surface can increase the contact area between the rubber pad 59 and the first fixing plate 53 and the second fixing plate 55, thereby improving the stability during clamping.

[0028] Furthermore, the two clamps 58 are fixedly connected by fixing bolts 510 at both ends. The two fixing bolts 510 fix the left and right ends of the clamps 58, so that the two clamps 58 clamp the fixing plate 1 53 and the fixing plate 2 55, thereby fixing the position of the fixing plate 1 53 and the fixing plate 2 55 by the clamps 58.

[0029] Working principle: In use, when the scraper blade 6 needs to be installed, insert the insertion rod 56 and the limiting plate 57 into the slot 52. The limiting plate 57 limits the scraper blade 6 to prevent rotation. Secure the two clamps 58 onto the first fixing plate 53 and the second fixing plate 55, and install the two fixing bolts 510 to fix the clamps 58 in the position of the first fixing plate 53 and the second fixing plate 55. This completes the installation of the scraper blade 6. The installation structure 5 allows for quick installation and removal of the scraper blade 6, improving installation efficiency and facilitating cleaning. After the drive shaft 1 is installed, its rotation drives the scraper blade... Arm 2 rotates, and scraper arm 2 drives scraper 6 to clean the sludge at the bottom of the sedimentation tank. When it needs to be installed in sedimentation tanks of different depths, scraper 6 is pressed against the bottom of the sedimentation tank. Scraper 6 drives support rod 42 to move upward, causing spring 43 to be compressed under pressure. This causes support rod 42 to retract into support rod 41. The elastic force of spring 43 pushes support rod 42 downward, so that scraper 6 is always pressed against the bottom of the sedimentation tank, thereby improving the cleaning effect. The downward pressing structure 4 allows the scraper to be adapted to sedimentation tanks of different depths, improving its applicability. It also ensures that scraper 6 is always pressed against the bottom of the sedimentation tank, thus improving the cleaning effect.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
