After the cleaning plate cleans the inner wall of the shovel, it returns to its original position; 3. When the sludge enters the centrifugal housing, the working motor is started, the rotating disk rotates, and the flinging plate rotates to fling the sludge in the centrifugal housing to generate a centrifugal force. The centrifugal force is much greater than the gravity, separating the water and sludge in the sludge. Under the action of the centrifugal force, the denser sludge is flung to the inner wall of the centrifugal housing and is transported to the sludge box through the sewage pipe, while the water remains in the middle position and is transported to the water storage tank through the water pipe.

[0016] The present invention will be further described in detail below with reference to all the drawings.

[0017] An embodiment of the present invention discloses a sludge cleaning device for land improvement.

[0018] Referring to Figure 1 and Figure 2 , a sludge cleaning device for land improvement includes a vehicle body 1 and a suspension arm 11 installed at the front of the vehicle body 1. A connecting frame 12 is connected to the end of the suspension arm 11. A transfer cylinder 2 is fixedly installed inside the connecting frame 12. A feed inlet 21 is opened at the top of the transfer cylinder 2. A delivery pipe 22 communicating with the transfer cylinder 2 is provided on the side wall of the connecting frame 12. A centrifugal dewatering assembly 6 communicating with the delivery pipe 22 is arranged inside the vehicle body 1. A rotating cylinder 3 sleeved outside the transfer cylinder 2 is rotatably connected to the connecting frame 12. Two digging shovels 31 are fixedly connected to the rotating cylinder 3. The two digging shovels 31 are symmetrically installed on the rotating cylinder 3. A material inlet 32 matching the digging shovels 31 is opened on the rotating cylinder 3. A spiral shaft 23 for conveying sludge is rotatably connected inside the transfer cylinder 2.

[0019] After the connecting frame 12 is moved to the sludge location through the suspension arm 11, the rotating cylinder 3 rotates, the rotating cylinder 3 drives the digging shovels 31 to rotate, and at the same time the vehicle body 1 moves. The digging shovels 31 dig up the sludge and continue to rotate. When the material inlet 32 coincides with the feed inlet 21, the sludge in the digging shovels 31 enters the transfer cylinder 2 through the material inlet 32 and the feed inlet 21. The spiral shaft 23 rotates and squeezes and conveys the sludge in the transfer cylinder 2, and is conveyed to the centrifugal dewatering assembly 6 through the delivery pipe 22 for dewatering work.

[0020] Referring to Figure 2 and Figure 3 , a driving motor 4 is installed on the connecting frame 12. The output shaft of the driving motor 4 is coaxially and fixedly connected to the spiral shaft 23. Starting the driving motor 4, the spiral shaft 23 rotates and squeezes and conveys the sludge in the transfer cylinder 2, and is conveyed to the centrifugal dewatering assembly 6 through the delivery pipe 22 for dewatering work. The output shaft of the driving motor 4 is connected to the end of the rotating cylinder 3 through a connecting rod 33. During the process of the driving motor 4 driving the spiral shaft 23 to rotate, the driving motor 4 drives the transfer cylinder 2 to rotate, the rotating cylinder 3 drives the digging shovels 31 to rotate, and at the same time the vehicle body 1 moves. The digging shovels 31 dig up the sludge and continue to rotate. When the material inlet 32 coincides with the feed inlet 21, the sludge in the digging shovels 31 enters the transfer cylinder 2 through the material inlet 32 and the feed inlet 21.

[0021] Referring to Figure 2 , Figure 4 and Figure 5, a cleaning plate 5 is arranged inside the digging shovel 31, and a moving component for reciprocating the cleaning plate 5 inside the digging shovel 31 is arranged inside the rotating cylinder 3. Among them, the moving component includes a moving screw 51. The rotating cylinder 3 is provided with a connecting notch 34 that cooperates with the digging shovel 31. The moving screw 51 is located inside the connecting notch 34 and is rotatably connected to the rotating cylinder 3. A moving rod 52 is fixedly connected to the cleaning plate 5, and a moving block 53 that is threadedly connected to the moving screw 51 is fixedly connected to the end of the moving rod 52. When the moving screw 51 rotates, the moving block 53 drives the cleaning plate 5 to move inside the digging shovel 31 to clean the inner wall of the digging shovel 31.

[0022] One end of the moving screw 51 is coaxially and fixedly connected with a first gear 54, and the other end of the moving screw 51 is coaxially and fixedly connected with a second gear 55. Both the first gear 54 and the second gear 55 are rotatably connected to the rotating cylinder 3. A third gear 56 that meshes with the second gear 55 is rotatably connected inside the rotating cylinder 3. Two gear notches 35 are provided on the inner wall of the rotating cylinder 3. The first gear 54 and the third gear 56 are located inside the two gear notches 35 and protrude from the gear notches 35. The transfer cylinder 2 is fixedly installed with a first arc-shaped rack 24 and a second arc-shaped rack 25 on one side along the rotation direction of the rotating cylinder 3 from the feed port 21. Among them, the first arc-shaped rack 24 meshes with the first gear 54, and the second arc-shaped rack 25 meshes with the third gear 56.

[0023] During the rotation of the rotating cylinder 3, after the sludge in one digging shovel 31 enters the transfer cylinder 2 and continues to rotate, the first gear 54 inside the rotating cylinder 3 first meshes with the first arc-shaped rack 24. The first gear 54 rotates and drives the moving screw 51 to rotate, so that the cleaning plate 5 inside the digging shovel 31 moves to clean the inner wall of the digging shovel 31. After the rotating cylinder 3 continues to rotate by ninety degrees, the first gear 54 separates from the first arc-shaped rack 24. The transfer cylinder 2 continues to rotate, and the third gear 56 meshes with the second arc-shaped rack 25. The third gear 56 rotates to drive the second gear 55 to rotate, so that the moving screw 51 rotates in the reverse direction, thereby causing the cleaning plate 5 inside the digging shovel 31 to move. After the cleaning plate 5 cleans the inner wall of the digging shovel 31 and resets, after the rotating cylinder 3 continues to rotate by ninety degrees, the position of the cleaning plate 5 inside the digging shovel 31 is reset. After the sludge inside the digging shovel 31 falls into the transfer cylinder 2 under the influence of gravity, the cleaning plate 5 reciprocates once inside the digging shovel 31 to clean the inner wall of the digging shovel 31. After the cleaned digging shovel 31 continues to dig sludge for work, the other digging shovel 31 continues to move to clean the digging shovel 31.

[0024] Refer to Figure 1 and Figure 6, the centrifugal dehydration assembly 6 includes a centrifugal housing 61, a water delivery pipe 62, a sewage discharge pipe 63, a working motor 64 and a rotating disk 65. The centrifugal housing 61 is placed horizontally. The end of the delivery pipe 22 far from the transfer cylinder 2 communicates with the top of the centrifugal housing 61. A delivery pump body connected to the delivery pipe 22 is provided on the vehicle body 1. The working motor 64 is installed at the end of the centrifugal housing 61 far from the delivery pipe 22. The output shaft of the working motor 64 is coaxially and fixedly connected to the rotating disk 65. A plurality of flapping plates 66 are circumferentially and equidistantly arranged on the rotating disk 65. The water delivery pipe 62 extends into the centrifugal housing 61 from the end of the centrifugal housing 61 far from the drive motor 4. The water delivery pipe 62 is located at the middle position among a plurality of flapping plates 66. The sewage discharge pipe 63 is located below the centrifugal housing 61 near the rotating disk 65. The sewage discharge pipe 63 is communicated with the centrifugal housing 61 through a buffer pipe.

[0025] When the sludge enters the centrifugal housing 61, start the working motor 64, the rotating disk 65 rotates, and the flapping plates 66 rotate and swing the sludge in the centrifugal housing 61 to generate centrifugal force. The centrifugal force is much greater than the gravity, separating the water and sludge residues in the sludge. Under the action of the centrifugal force, the denser sludge residues are thrown to the inner wall of the centrifugal housing 61 and are transported to the sludge box 8 through the sewage discharge pipe 63, while the water remains in the middle position and is transported to the water filling tank 7 through the water delivery pipe 62.

[0026] A water filling tank 7 and a sludge box 8 are installed on the vehicle body 1. The water filling tank 7 is communicated with the water delivery pipe 62, and the sludge box 8 is communicated with the sewage discharge pipe 63. The water enters the water filling tank 7, and the sludge enters the sludge box 8. After the sludge is dehydrated, its volume and weight are greatly reduced, reducing the costs of subsequent transportation, storage and treatment.

[0027] The implementation principle of the present invention is as follows: The connecting frame 12 is moved to the sludge through the suspension arm 11. Start the drive motor 4, and the rotating cylinder 3 drives the digging shovel 31 to rotate. At the same time, the vehicle body 1 moves. After the digging shovel 31 digs up the sludge, it continues to rotate. When the feeding port 32 coincides with the feeding inlet 21, the sludge in the digging shovel 31 enters the transfer cylinder 2 through the feeding port 32 and the feeding inlet 21. The drive motor 4 drives the spiral shaft 23 to rotate, continuously conveying the sludge. The rotating cylinder 3 continues to rotate, so that the digging shovel 31 on the rotating cylinder 3 continues to work, realizing continuous cleaning of the sludge and improving the cleaning speed; when the sludge enters the centrifugal housing 61, start the working motor 64, the rotating disk 65 rotates, and the flapping plates 66 rotate to swing the sludge in the centrifugal housing 61 to generate centrifugal force. Under the action of the centrifugal force, the denser sludge residues are thrown to the inner wall of the centrifugal housing 61 and are transported to the sludge box 8 through the sewage discharge pipe 63, while the water remains in the middle position and is transported to the water filling tank 7 through the water delivery pipe 62, facilitating subsequent treatment.

[0028] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
