[0025] refer to Figure 1 , Fig.10and Fig.11 As shown, the driving assembly 6 includes a driving column 61 installed between the sewage filter box 1 and the centering column 36 for connection, and a driving rod 62 installed between the centering seat 46 and the sewage filter box 1 for connection, and one end of the driving column 61 and the driving rod 62 penetrates the sewage filter box 1 and is fixedly connected to the second belt pulley 64 and the first belt pulley 63, and a belt strip 66 is commonly connected between the second belt pulley 64 and the first belt pulley 63, and a servo motor 65 is fixedly connected to the bottom of the sewage filter box 1, and the servo motor 65 is used to drive the second belt pulley 64 to rotate.

[0026] Through the above technical solution: When in use; In the first step, when it is necessary to clean the impurities on the surface of the filter screen 11 inside the sewage filter box 1, the servo motor 65 drives the second belt pulley 64 to rotate, and then the second belt pulley 64 rotates and transmits with the belt strip 66 and drives the first belt pulley 63 to rotate. At this time, the first belt pulley 63 rotates to drive the driving rod 62 to rotate inside the sewage filter box 1, and the driving rod 62 rotates to drive the centering seat 46 to rotate synchronously, and the centering seat 46 rotates to drive the crank 45 to rotate, and the crank 45 moves along the outer circumference of the centering seat 46, and the crank 45 rotates to drive the shaft column 44 in one of the receiving grooves 43 to the inside of the horizontal frame 41. During this process, the shaft column 44 does not move to the inside of the other receiving groove 43 along the limiting groove 42, so that the positions of the horizontal frame 41 and the connecting plate 26 remain unchanged, so that the cleaning scraper 25 remains in contact with the surface of the filter screen 11.

[0027] In the second step, when the second belt pulley 64 rotates, the driving column 61 rotates synchronously along the inside of the sewage filter box 1, and then the centering column 36 moves along the outer circle of the driving column 61. At this time, the rotation of the centering column 36 drives one of the wave rods 35 to move into one of the guide grooves 33 opened outside the guide plate 23, and one of the wave rods 35 moves along one of the guide grooves 33 to the inside of the second guide groove 32, and one of the wave rods 35 moves along the inside of the second guide groove 32 and forms a conflict with it, which is used to drive the guide cylinder 22 to rotate between the two support frames 21, and the rotation of the guide cylinder 22 drives the two guide plates 23 to rotate and rotates the direction dividing grooves 34 and the guide grooves 33 opened on their outside, so that the second guide groove 32 and one of the wave rods 35 always keep in contact, which is conducive to the continuous rotation of the guide cylinder 22, and one of the wave rods 35 After the wave rod 35 moves to the inside of the second guide groove 32, one of the connecting arc frames 37 approaches the outside of the guide plate 23, waiting for one of the branch grooves 34 to overlap with one of the connecting arc frames 37. As the guide cylinder 22 rotates, the slide groove 54 is driven to rotate, and then the slide groove 54 and the slider 57 form a conflict and drive the slider 57 to rotate. At this time, the slider 57 rotates to drive the sleeve 55 and the connecting column 24 to rotate. Then the connecting column 24 rotates to drive the side plate 53 to rotate along the side groove 58, and the side plate 53 and the side groove 58 conflict and drive the sleeve 52 to rotate along the rotating chamber 51. Then, the connecting column 24 drives the cleaning scraper 25 to rotate synchronously while rotating, so that the cleaning scraper 25 rotates and scrapes the filter screen 11 to clean the impurities on the surface of the filter screen 11, thereby avoiding the occurrence of blockage on the surface of the filter screen 11, which is conducive to the rapid passage of sewage.

[0028] In the third step, after one of the wave rods 35 moves out along the inside of the second guide groove 32 and the other guide groove 33, the top of one of the connecting arc frames 37 moves to the inside of one of the direction-dividing grooves 34. At this time, one of the wave rods 35 loses the temporary connection with the second guide groove 32, and instead, one of the connecting arc frames 37 remains connected with one of the direction-dividing grooves 34, and the top of one of the connecting arc frames 37 slowly moves out along the inside of one of the direction-dividing grooves 34 and moves to the outside of the guide cylinder 22. During this process, one of the connecting arc frames 37 moves along the outside of the guide cylinder 22 to the inside of the other guide groove 33 corresponding to one of the direction-dividing grooves 34. During this process, the guide cylinder 22 is stationary between the two support frames 21, and the cleaning scraper 25 and the filter screen 11 remain in a vertical state. In addition, when the cleaning scraper 25 and the filter screen 11 remain in a vertical state, the shaft column 44 has been moved along the limit The inside of the groove 42 moves to the inside of the other receiving groove 43. As the crank 45 continues to rotate, the shaft column 44 is driven to rotate and form a conflict with the other receiving groove 43, thereby pushing the horizontal frame 41 to move to the right along one side of the support frame 21, so that the movement of the horizontal frame 41 drives the connecting plate 26 to move synchronously, and then the connecting plate 26 pulls the positioning cylinder 27 and drives the connecting column 24 to move along the guide plate 23, the slide groove 54 and the inside of the rotating chamber 51, so that the movement of the connecting column 24 drives the cleaning scraper 25 to separate from the filter screen 11, and the movement of the connecting column 24 drives the sliding sleeve 55 and the slider 57 to move horizontally along the inside of the guide cylinder 22 and the slide groove 54, and then the side plate 53 moves along the inside of the side groove 58, and the spring 56 is squeezed between the sliding sleeve 55 and the sleeve 52, thereby ensuring the stable movement of the connecting column 24, and then achieving the goal of keeping the rotating cleaning scraper 25 in a vertical state, and then separating the vertical cleaning scraper 25 from the filter screen 11.

[0029] In the fourth step, when the horizontal movement of the horizontal frame 41 drives the cleaning scraper 25 to separate from the filter screen 11, and the cleaning scraper 25 contacts one of the support frames 21, the shaft column 44 moves along the inside of the other receiving groove 43 to the inside of the limiting groove 42. During this process, the shaft column 44 does not move to the inside of one of the receiving grooves 43 along the inside of the limiting groove 42. At this time, the positions of the horizontal frame 41 and the connecting plate 26 remain unchanged, so that the position of the cleaning scraper 25 remains stable after adjustment, and after passing through the top of one of the connecting arc frames 37 along the outside of the guide cylinder 22 to the inside of another guide groove 33, and the top part of one of the connecting arc frames 37 passes through the inside of the other guide groove 33, the shaft column 44 has moved along the inside of the limiting groove 42 to one of the receiving grooves 43. Inside a receiving groove 43, as the crank 45 continues to rotate, the shaft column 44 is driven to rotate and form a conflict with one of the receiving grooves 43, thereby pushing the horizontal frame 41 to move to the left along one side of the support frame 21, and is used to drive the connecting column 24 and the cleaning scraper 25 to move and reset to approach the surface of the filter 11 after the conflict, and then another wave rod 35 moves to the inside of one of the dividing grooves 34, and then another wave rod 35 moves to the inside of the first guide groove 31 through one of the dividing grooves 34, and is used to drive the guide cylinder 22 to rotate in the opposite direction between the two support frames 21, so that the cleaning scraper 25 rotates forward and backward along the surface of the filter 11, which is beneficial to increase the friction between the cleaning scraper 25 and the surface of the filter 11, and helps to more effectively remove dirt and impurities.
