[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a reciprocating scraper with a quick-change scraper blade. (See also...) Figures 1-4 A reciprocating sludge scraper with quick-change scraper blades includes a sedimentation tank 1. A frame 7 is movably connected to the inner wall of the sedimentation tank 1. A first hydraulic cylinder 4 is used in conjunction with the frame 7. The first hydraulic cylinder 4 is fixedly installed on the inner wall of the sedimentation tank 1. A second hydraulic cylinder 5 is fixedly installed on the top of the sedimentation tank 1. There are two second hydraulic cylinders 5. A connecting plate 9 is provided on the inner wall of the frame 7. There are several connecting plates 9. A scraper 10 is fixedly connected to the bottom of the connecting plate 9. A replacement mechanism 2 is provided on both sides of the top of the connecting plate 9.

[0024] The replacement mechanism 2 includes fixed plates 205, with several sets of two fixed plates 205. The bottoms of the two fixed plates 205 are fixedly connected to the top of the connecting plate 9. Threaded sleeves 207 are fixedly connected to opposite sides of the two fixed plates 205. Threaded rods 206 are threadedly connected to the inner walls of the threaded sleeves 207. One end of the threaded rod 206 passes through to one side of the fixed plate 205 and contacts a buckle plate 201. A slider 202 is fixedly connected to the bottom of the buckle plate 201. The surface of the slider 202 is slidably connected to the inner wall of the connecting plate 9. A limit block 203 is fixedly connected to the top of the frame 7. There are several 203s. The top of the limiting block 203 is fixedly connected to the baffle 204. The surface of one of the limiting blocks 203 is in close contact with the inner wall of the buckle plate 201, and the bottom of the baffle 204 is in contact with the top of the buckle plate 201. By setting the replacement mechanism 2, the user can easily replace the scraper 10, eliminating the need for the user to disassemble the scraper 10 by cutting. At the same time, it can increase the efficiency and effect of the user when replacing the scraper 10, and achieve the purpose of making it convenient for the user to replace the worn scraper 10.

[0025] Reference Figure 4 The inner wall of the connecting plate 9 is provided with two sliding grooves 17. The inner cavity of the sliding groove 17 is in contact with the surface of the slider 202. By setting the sliding groove 17, the slider 202 can be provided with a trajectory for movement under the action of the sliding groove 17, so as to avoid the slider 202 getting stuck when moving, thus achieving the purpose of preventing the slider 202 from being unable to move.

[0026] Reference Figure 3 and Figure 4The top of the connecting plate 9 and the frame 7 are respectively fixedly connected to a first limiting frame 15 and a second limiting frame 16. There are several first limiting frames 15, and two in each group. There are two second limiting frames 16. A reinforcing rod 8 is snapped between the inner walls of several first limiting frames 15 and second limiting frames 16. One end of the reinforcing rod 8 is fixedly connected to a first top block 18. By setting the first limiting frames 15 and the second limiting frames 16 to work together, it is convenient for the user to install the reinforcing rod 8, thereby increasing the overall stability of the connecting plate 9 and the frame 7.

[0027] Reference Figure 3 Limiting plates 14 are fixedly connected to both sides of the reinforcing rod 8. There are several sets of limiting plates 14, and each set contains two plates. The inner wall of the first limiting frame 15 is in close contact with the surface of two of the limiting plates 14, and the surface of the other two limiting plates 14 is in close contact with the inner wall of the second limiting frame 16. By setting the limiting plates 14, the stability and firmness of the connection between the reinforcing rod 8 and the first limiting frame 15 and the second limiting frame 16 can be further increased.

[0028] Reference Figure 3 The second hydraulic cylinder 5 has a movable plate 6 fixedly connected to its telescopic end. Movable rods 13 are fixedly connected to both sides of the movable plate 6. An auxiliary plate 3 is fixedly connected to one side of the inner wall of the sedimentation tank 1. There are two sets of auxiliary plates 3, with two plates in each set. The opposite sides of the two auxiliary plates 3 are movably connected to the two sides of the movable plate 6. The opposite ends of the two movable rods 13 penetrate into the inner walls of the two auxiliary plates 3 and are movably connected to the inner walls of the auxiliary plates 3. A second top block 11 is fixedly connected to one side of the movable plate 6. The second top block 11 works in conjunction with the first top block 18. By setting the second hydraulic cylinder 5, movable plate 6, movable rods 13, auxiliary plate 3, and second top block 11 to work together, the movable plate 6 can be moved when the telescopic end of the second hydraulic cylinder 5 is extended or retracted. This allows the movable rods 13 to move within the auxiliary plate 3, enabling the second top block 11 to contact the first top block 18. This separates the reinforcing rod 8 from the first limiting frame 15 and the second limiting frame 16, thus enabling the second top block 11 to contact the first top block 18.

[0029] Reference Figure 2 The inner wall of the auxiliary plate 3 is provided with a through groove 12, and the inner cavity of the through groove 12 is movably connected to the surface of the movable rod 13. By setting the through groove 12, the movable rod 13 can be provided with a trajectory for rotation and movement under the action of the through groove 12, so as to avoid the movable plate 6 from getting stuck when moving, and thus achieve the purpose of preventing the movable rod 13 from being unable to rotate and move.

[0030] Working principle: To facilitate the user's replacement of the worn scraper 10 with enhanced protection, the user first activates the second hydraulic cylinder 5 via an external power supply and switch. The telescopic end of the second hydraulic cylinder 5 drives the movable plate 6 to move. The moving movable plate 6 drives the movable rod 13 to move and rotate in the auxiliary plate 3 through the through groove 12. Simultaneously, this causes the second top block 11 to contact the first top block 18, causing the first top block 18 to move. The moving second top block 11 drives the reinforcing rod 8 to move, causing the limiting plate 14 to contact the first limiting frame 15 and... Separate the second limiting frame 16, remove the reinforcing rod 8, and then the user rotates the threaded rod 206, causing the threaded rod 206 to move within the threaded sleeve 207. As the threaded rod 206 rotates and moves, it moves away from the buckle plate 201. After rotating the threaded rod 206 until it separates from the threaded sleeve 207, the user moves the buckle plate 201 to drive the slider 202 to slide in the slide groove 17, separating the buckle plate 201 from the limiting block 203 and the baffle 204. Then, the user takes out the scraper 10 that needs to be replaced and installs the new scraper 10.

[0031] It is worth noting that the first hydraulic cylinder 4 in this application is prior art and provides power for the reciprocating movement of the scraper 10. The connection method between the first hydraulic cylinder 4 and the scraper 10 does not need to be elaborated in this application. The scraper 10 in this application can be made of nylon material. The scraper 10 made of nylon material can effectively increase the wear resistance during use.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
