Description

Technical Field

[0001] This invention relates to the field of sludge separation technology, and more specifically to a sludge separation device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering projects. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, water intakes, canals, ferries, rafts, and fishways to achieve their goals.

[0003] After irrigation canals are completed and put into use for a period of time, silt will accumulate at the bottom, seriously affecting the smooth flow of water. For large canals, the usual method of cleaning is to use an excavator bucket to remove the silt from the bottom. However, for small canals used for farmland irrigation, the width is generally narrow, and there is not enough working space for the excavator bucket. Therefore, it is usually necessary to manually use tools such as shovels to dig and remove the silt, or to use a mud pump to directly suck out the silt for cleaning. However, since the silt contains a lot of mud and debris, it may cause the mud pump to become clogged. When the mud pump is used, it sucks out the silt and water mixture in the canal and discharges it directly onto the ground on both sides of the canal. The silt slurry contains a lot of water, and after the silt slurry spreads, it makes the ground muddy, which is not convenient for workers to carry out subsequent treatment of the silt. It is necessary to wait for the water in the silt slurry to drain naturally before the silt can be collected and cleaned.

[0004] Moreover, regardless of which of the above methods is used to clean the silt from the canal, the canal is long and manual cleaning requires a lot of labor. While using a sludge pump can reduce the labor intensity of manual digging and dredging of silt, it still requires manual relocation of the sludge pump. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides a sludge separation device for water conservancy projects to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A sludge separation device for water conservancy projects includes a separation box with an open right side. The top of the separation box is tilted to the left. A sludge removal side plate is fixedly connected to the bottom right side of the front and rear side plates. A shovel plate is fixedly installed between the two sludge removal side plates. The top of the shovel plate is inclined with the left side higher than the right side. The bottom plate of the separation box is horizontal and an arc-shaped guide plate is fixedly installed on its top. The top surface of the arc-shaped guide plate is arc-shaped with the left side lower than the right side, and its right side abuts against the left side of the shovel plate. A separation conveyor belt is rotatably installed between the front and rear side plates of the separation box. Several circumferentially equidistant sludge separation components are installed on the outer side of the separation conveyor belt. A sludge collection box is fixedly installed at the top of the left side of the separation box, and a sludge discharge component is installed inside the sludge collection box.

[0007] Preferably, a dredging conveying groove is provided on the top inclined surface of the shovel plate, and two dredging conveying rollers are rotatably installed between the front and rear sides of the dredging conveying groove. A dredging conveying belt is installed between the two dredging conveying rollers. The top surface of the dredging conveying belt is flush with the inclined surface of the shovel plate, and sealing blocks are installed in the gaps between the left and right ends of the dredging conveying belt and the left and right sides of the dredging conveying groove.

[0008] Preferably, a follower wheel is rotatably mounted on the front side of the dredging side plate located on the front side, the bottom of the follower wheel is lower than the bottom surface of the dredging side plate, and a follower gear is coaxially fixedly mounted on the follower wheel. A dredging gear that meshes with the follower gear is coaxially fixedly mounted on the front end of the dredging conveying roller located at the left end of the dredging conveying trough.

[0009] Preferably, a mud-gathering plate is rotatably mounted on the right end of each of the two dredging side plates. The mud-gathering plate is rotatably connected to the dredging side plate via a pin. An angle-adjusting worm gear is coaxially fixedly mounted on the top end of the pin of the mud-gathering plate. An "L"-shaped bracket is fixedly mounted on the opposite sides of the two dredging side plates. An angle-adjusting shaft is rotatably mounted between the two brackets. An angle-adjusting worm is coaxially slidably mounted on both ends of the angle-adjusting shaft. Each angle-adjusting worm meshes with the angle-adjusting worm gear on the same side. A worm spring sleeved on the outside of the angle-adjusting shaft is abutted between the angle-adjusting worm and the bracket. An abutment roller is rotatably mounted on the end of the mud-gathering plate away from the dredging side plate.

[0010] Preferably, the sludge separation assembly includes a separation bucket with a top opening and a semi-circular bottom portion, and an inner separation bucket located inside the separation bucket and also having a semi-circular bottom portion. The separation bucket is fixedly installed on the outer side of the separation conveyor belt. Two inner bucket slide rods are radially penetrated and slidably installed at both ends of the semi-circular bottom portion of the separation bucket. One end of each inner bucket slide rod located inside the separation bucket is fixedly connected to the outer side of the inner separation bucket. A counterweight impact rod is fixedly installed at one end of each inner bucket slide rod located outside the separation bucket. Both the separating bucket and the inner separating bucket have several separating mesh holes on their bottom arc surfaces, and the diameter of the separating mesh holes at the bottom of the separating bucket is larger than the diameter of the separating mesh holes at the bottom of the inner separating bucket.

[0011] Preferably, a drainage guide plate located below each separation bucket is fixedly installed on the outer side of the separation conveyor belt. The front and rear ends of the drainage guide plate are inclined downward and abut against the front and rear inner walls of the separation box, respectively. Several drainage mesh holes are opened on the front and rear side plates of the separation box near the opening.

[0012] Preferably, two separating conveyor rollers are rotatably installed between the front and rear side plates of the separating box, the separating conveyor belt is installed between the two separating conveyor rollers, and the separating bucket and the separating conveyor belt are fixedly connected by bolts passing through them. Grooves corresponding to the bolt positions are opened on the outer side of the two separating conveyor rollers. When the two separating conveyor rollers drive the separating conveyor belt to rotate, the end of the bolt on the inner side of the separating conveyor belt can enter the groove. A separating conveyor motor is fixedly installed on the front side of the separating box, and the output shaft of the separating conveyor motor is coaxially fixedly connected to one of the separating conveyor rollers.

[0013] Preferably, a mud collection trough extends through the interior of the mud collection box and the separation box, and a mud collection inclined plate with a lower left side and a higher right side is fixedly installed on the bottom surface inside the mud collection box. A mud discharge trough located on the left side of the mud collection inclined plate extends through the bottom of the mud collection box. The sludge discharge assembly includes a semi-circular trough plate installed below the opening of the sludge discharge trough. A sludge discharge pipe coaxial with the semi-circular trough plate and communicating with the inside of the sludge collection box is fixedly installed on the front side of the sludge collection box. A sludge discharge auger located inside the semi-circular trough plate and extending into the sludge discharge pipe is rotatably installed on the rear side of the sludge collection box. A sludge discharge motor is installed on the rear side of the sludge collection box. The output shaft of the sludge discharge motor is coaxially and fixedly connected to the sludge discharge auger.

[0014] Preferably, track rails are installed on both the front and rear sides of the separation box, a track slider is slidably installed in each track rail, a track bracket is fixedly connected to the side of each track slider away from the separation box, a track wheel set is installed on each track bracket, and a power source for driving the track wheel set is installed on each track bracket.

[0015] Preferably, a height adjusting screw is rotatably installed between the upper and lower ends of the track slide rail. The height adjusting screw passes through the track slider and is threadedly engaged with it. A synchronous sprocket set is installed between the top ends of the two height adjusting screws. A height adjusting motor is installed on one of the track slide rails. The output shaft of the height adjusting motor is coaxially and fixedly connected to one of the height adjusting screws.

[0016] The beneficial effects of this invention are as follows: 1. When the separation box moves, the sludge can be scooped up by the shovel plate. The sludge enters the separation box along the inclined surface of the shovel plate and is placed on the arc surface of the arc-shaped guide plate. The separation conveyor belt can drive several sludge separation components to move counterclockwise in a circumferential direction. When each sludge separation component moves to the bottom of the separation box, it can scoop up the sludge and transport it to the top of the separation box as the separation conveyor belt rotates. During the transportation process, the sludge separation components can filter the water in the sludge.

[0017] 2. When the sludge separation component containing sludge moves to the left side of the separation conveyor belt, the opening of the sludge separation component faces downward, and the sludge can fall into the inside of the sludge collection box. Then, it is discharged to the outside of the sludge collection box by the sludge discharge component. A trolley can be placed on the ground on one side of the canal. When the sludge discharge component discharges the sludge from the sludge collection box, it falls directly into the trolley for collection.

[0018] 3. To enable the sludge to enter the separation box more quickly and efficiently, the sludge conveyor belt rotates counterclockwise while the separation box moves. After the shovel scoops up the sludge, it can be transported towards the separation box on the surface of the sludge conveyor belt, thereby improving the sludge cleaning efficiency and preventing the sludge from accumulating on the inclined surface of the shovel. The sealing block can be made of rubber and seals against the outer surface of the sludge conveyor belt. It can fill the gap between the sludge conveying trough and the sludge conveyor belt, preventing the sludge from entering the sludge conveying trough and also scraping off the sludge adhering to the outer surface of the sludge conveyor belt.

[0019] 4. When the width of the ditch to be cleaned is greater than the width of the separation box, the two mud-gathering plates can be rotated outwards so that the end away from the dredging side plate abuts against the side wall of the ditch. When the separation box moves to the right, the two mud-gathering plates can gather the sludge located in the front and rear sides of the separation box to the front of the shovel plate, and then be scooped up by the shovel plate. This method is suitable for dredging ditches of different widths.

[0020] 5. The separating bucket can scoop up silt. After the separating bucket is removed from the water surface, the water in the silt can be filtered through the separating mesh, leaving only silt inside the inner separating bucket, thus achieving the separation of water from the silt. When the separating bucket moves to the left side of the top of the separating conveyor belt, the silt in the inner separating bucket falls downward into the sludge collection box. The inner separating bucket falls downward under its own weight, pushing the silt downward. The counterweight impact rod strikes the bottom of the separating bucket, causing vibration in the separating bucket and the inner separating bucket, which can cause the silt inside to fall off.

[0036] The following will refer to the appendix. Figures 1-14 The description provides a detailed description of various embodiments of the present invention.

[0037] Example 1: A sludge separation device for water conservancy projects, as shown in the attached document. Figures 1-14 As shown, the separation box 1 has an opening on the right side. The separation box 1 is composed of front and rear side plates, a left side plate, a top plate, and a bottom plate. The top of the separation box 1 is inclined to the left. The bottom right side of the front and rear side plates is fixedly connected to dredging side plates 2. A shovel plate 3 is fixedly installed between the two dredging side plates 2. The top of the shovel plate 3 is a slope that is higher on the left and lower on the right, and its right end is pointed. The bottom surface of the shovel plate 3 is flush with the bottom of the dredging side plate 2. The bottom plate of the separation box 1 is horizontal and an arc-shaped guide plate 4 is fixedly installed on its top. The top surface of the arc-shaped guide plate 4 is an arc that is lower on the left and higher on the right, and its right side abuts against the left side of the shovel plate 3. When the separation box 1 is placed at the bottom of the water channel, the bottom surface of the shovel plate 3 is in contact with the bottom surface of the water channel. When the separation box 1 moves, the sludge can be scooped up by the pointed end of the right side of the shovel plate 3. The sludge enters the separation box 1 along the slope of the shovel plate 3 and is placed on the arc surface of the arc-shaped guide plate 4. A separation conveyor belt 5 is rotatably mounted between the front and rear side plates of the separation box 1. Several circumferentially equidistant sludge separation components 6 are mounted on the outer surface of the separation conveyor belt 5. The top opening of each sludge separation component 6 is shown in the attached diagram. Figure 5As shown, the separating conveyor belt 5 rotates counterclockwise, which drives several sludge separation components 6 to move counterclockwise circumferentially. When each sludge separation component 6 moves to the bottom of the separation box 1, the end of the sludge separation component 6 away from the separating conveyor belt 5 abuts against the arc surface of the arc guide plate 4. Then, the sludge separation component 6 can scoop up the sludge and transport it to the top of the separation box 1 as the separating conveyor belt 5 rotates. During the transportation process, the sludge separation component 6 can filter the water in the sludge. A sludge collection box 7 is fixedly installed at the top left side of the separation box 1. A sludge discharge assembly 8 is installed inside the sludge collection box 7. When the sludge separation assembly 6, which contains sludge, moves to the top of the separation box 1 and to the left side of the separation conveyor belt 5, the opening of the sludge separation assembly 6 faces downward, and the sludge inside can fall into the sludge collection box 7. Then, it is discharged to the outside of the sludge collection box 7 by the sludge discharge assembly 8. A trolley can be placed on the ground on one side of the canal. When the sludge discharge assembly 8 discharges the sludge from the sludge collection box 7, it falls directly into the trolley.

[0038] Example 2, as shown in the appendix Figure 5 , Figure 7 As shown, a dredging conveying groove 9 is provided on the top inclined surface of the shovel plate 3. Two dredging conveying rollers 10 are rotatably installed between the front and rear sides of the dredging conveying groove 9. A dredging conveying belt 11 is installed between the two dredging conveying rollers 10. The top surface of the dredging conveying belt 11 is flush with the inclined surface of the shovel plate 3. Sealing blocks 12 are installed in the gaps between the left and right ends of the dredging conveying belt 11 and the left and right sides of the dredging conveying groove 9. To enable the sludge to enter the separation box 1 more quickly and efficiently, the sludge removal conveyor belt 11 rotates counterclockwise while the separation box 1 moves. After the shovel plate 3 scoops up the sludge, the sludge can be transported from the surface of the sludge removal conveyor belt 11 towards the separation box 1, thereby improving the sludge removal efficiency and preventing the sludge from accumulating on the inclined surface of the shovel plate 3. The sealing block 12 can be made of rubber and seal against the outer surface of the sludge removal conveyor belt 11. It can fill the gap between the sludge removal conveyor trough 9 and the sludge removal conveyor belt 11, preventing the sludge from entering the sludge removal conveyor trough 9. It can also scrape off the sludge adhering to the outer surface of the sludge removal conveyor belt 11.

[0039] Example 3, as shown in the appendix Figure 1 , Figure 3 , Figure 6 , Figure 8As shown, a follower wheel 13 is rotatably mounted on the front side of the dredging side plate 2. The bottom of the follower wheel 13 is lower than the bottom surface of the dredging side plate 2. The outer circumference of the follower wheel 13 can be made of rubber. When the dredging side plate 2 is in contact with the bottom surface of the water channel, the outer circumference of the follower wheel 13 can be squeezed. Then, when the separation box 1 moves to the right, the follower wheel 13 can roll clockwise on the bottom surface of the water channel. A follower gear 14 is coaxially fixedly mounted on the follower wheel 13. When the roller rotates clockwise, it can drive the follower gear 14 to rotate clockwise synchronously. The front end of the dredging conveying roller 10 located at the left end of the dredging conveying trough 9 is coaxially fixed with a dredging gear 15 that meshes with the follower gear 14. When the follower gear 14 rotates clockwise, it can drive the dredging gear 15 to rotate counterclockwise. The dredging gear 15 then drives the dredging conveying roller 10 connected to it to rotate counterclockwise synchronously, thereby causing the dredging conveying belt 11 to rotate counterclockwise, thus conveying the sludge into the separation box 1.

[0040] Example 4, as shown in the appendix Figures 1-7 , Figure 9 As shown, mud-gathering plates 16 are rotatably installed on the right ends of the two dredging side plates 2. The mud-gathering plates 16 are rotatably connected to the dredging side plates 2 by pins. The bottom of the mud-gathering plates 16 is flush with the bottom of the dredging side plates 2. By rotating the mud-gathering plates 16, the angle between them and the dredging side plates 2 can be adjusted. When the width of the water channel to be cleaned is greater than the width of the separation box 1, the two mud-gathering plates 16 can be rotated outwards so that the end away from the dredging side plates 2 abuts against the side wall of the water channel. When the separation box 1 moves to the right, the two mud-gathering plates 16 can gather the sludge located in the front and rear sides of the separation box 1 to the front of the shovel plate 3, and then be shoveled up by the shovel plate 3. This is suitable for dredging water channels of different widths. An angle adjusting worm gear 17 is coaxially fixedly installed at the top of the pin shaft of the mud-gathering plate 16. An "L"-shaped bracket 18 is fixedly installed on the opposite sides of the two dredging side plates 2. An angle adjusting shaft 19 is rotatably installed between the two brackets 18. An angle adjusting worm 20 is coaxially slidably installed at both ends of the angle adjusting shaft 19. The angle adjusting worm 20 can slide axially outside the angle adjusting shaft 19. When the angle adjusting shaft 19 rotates, it can drive the angle adjusting worm 20 to rotate. Each angle adjusting worm 20 meshes with the angle adjusting worm gear 17 on the same side. When it is necessary to adjust the angle of the two mud-gathering plates 16, it is only necessary to rotate the angle adjusting shaft 19. The angle adjusting shaft 19 drives the two angle adjusting worm 20 to rotate synchronously. The two angle adjusting worm 20 then drive the two angle adjusting worm gears 17 to rotate synchronously, so that the two mud-gathering plates 16 can rotate simultaneously to adjust the angle. As attached Figure 9As shown, a worm spring 21 sleeved on the outside of the angle adjusting shaft 19 is installed between the angle adjusting worm 20 and the bracket 18. When the distal end of the mud-gathering plate 16 abuts against the side wall of the water channel and moves with the separation box 1, if there is a protrusion on the side wall of the water channel, it will block the mud-gathering plate 16, making it impossible for the separation box 1 to move forward. This problem can be solved by setting the angle adjusting worm 20 to slide axially on the outside of the angle adjusting shaft 19 and applying the elastic force of the spring to it. Specifically, when the mud-gathering plate 16 encounters a protrusion, it will swing a certain angle towards the mud-shoveling plate 3 (this swing angle...). (Depending on the size of the protrusion on the side wall of the canal), the mud-gathering plate 16 drives the angle adjusting worm wheel 17 to rotate at a certain angle, and the angle adjusting worm wheel 17 moves the angle adjusting worm 20 axially a certain distance. The axial movement of the angle adjusting worm 20 compresses the worm spring 21. When the far end of the mud-gathering plate 16 passes the protrusion, the angle adjusting worm 20 is reset under the elastic force of the compressed worm spring 21, thereby driving the angle adjusting worm wheel 17 to rotate and reset. The angle adjusting worm wheel 17 then drives the mud-gathering plate 16 to swing toward the side wall of the canal, so that its far end abuts against the side wall of the canal again. The mud-gathering plate 16 is rotatably mounted with an abutment roller 22 at the end away from the dredging side plate 2. The abutment roller 22 can reduce the friction between the mud-gathering plate 16 and the side wall of the water channel. When the separation box 1 moves, the abutment roller 22 rolls along the side wall of the water channel.

[0041] Example 5, as shown in the appendix Figures 1-5 , Figures 10-13 As shown, the sludge separation assembly 6 includes a separation bucket 23 with a top opening and a semi-circular bottom portion, and an inner separation bucket 24 located inside the separation bucket 23 and also with a semi-circular bottom portion (the above state is the state when it is on the right side of the separation conveyor belt 5, at which time the opening of the separation bucket 23 faces upward; when it is on the left side of the separation conveyor belt 5, the opening of the separation bucket 23 faces downward, see attached figure). Figure 10 and Figure 12 The separating bucket 23 is fixedly installed on the outer side of the separating conveyor belt 5. Two inner bucket slide rods 25 are radially inserted and slidably installed at both ends of the semi-circular arc part at the bottom of the separating bucket 23. One end of each inner bucket slide rod 25 located inside the separating bucket 23 is fixedly connected to the outer side of the separating inner bucket 24. A counterweight impact rod 26 is fixedly installed at one end of each inner bucket slide rod 25 located outside the separating bucket 23. Both the separating bucket 23 and the separating inner bucket 24 have a number of separating mesh holes on their bottom arc surfaces, and the diameter of the separating mesh holes at the bottom of the separating bucket 23 is larger than the diameter of the separating mesh holes at the bottom of the separating inner bucket 24. In use, the separating conveyor belt 5 drives multiple separating buckets 23 to move counterclockwise in a circumferential direction. When the separating buckets 23 move to the arc surface of the arc guide plate 4, the separating buckets 23 can scoop up the silt on the arc guide plate 4. The silt is located inside the inner separating bucket 24 and is then transported counterclockwise by the separating conveyor belt 5. When the separating buckets 23 move out of the water surface, the water in the silt can be filtered through the separating mesh, so that only silt remains inside the inner separating bucket 24, thereby achieving the separation of water in the silt. When the separating bucket 23 containing sludge moves to the left side of the top of the separating conveyor belt 5, the openings of the separating bucket 23 and the inner separating bucket 24 face downwards, causing the sludge in the inner separating bucket 24 to fall downwards into the sludge collection box 7. At the same time, the inner separating bucket 24 also falls downwards under its own weight, pushing the sludge downwards. Simultaneously, the inner separating bucket 24 drives the inner bucket slide bar 25 to move, causing the counterweight impact bar 26 to strike the bottom of the separating bucket 23, stopping the inner separating bucket 24 from falling downwards, and generating vibrations in the separating bucket 23 and the inner separating bucket 24, which can cause the sludge inside to fall out.

[0042] Example 6, as shown in the appendix Figure 1 , Figure 10 , Figure 11 As shown, a drainage guide plate 27 located below each separation bucket 23 is fixedly installed on the outer side of the separation conveyor belt 5. The front and rear ends of the drainage guide plate 27 are inclined downward and abut against the front and rear inner walls of the separation box 1 respectively. Several drainage mesh holes 28 are opened on the front and rear side plates of the separation box 1 near the opening. To prevent the water filtered from the upper separating bucket 23 from flowing into the lower separating bucket 23, thereby dispersing the sludge in the lower separating bucket 23 and causing it to flow into the water channel, a drainage guide plate 27 is installed below each separating bucket 23. When the filtered water flows onto the drainage guide plate 27, the water can flow along its slope to the front and rear side plates of the separating box 1, and then flow into the water channel through the drainage mesh 28.

[0043] Example 7, as shown in the appendix Figure 1 , Figure 5 , Figure 10 , Figure 12As shown, two separating conveyor rollers 29 are rotatably installed between the front and rear side plates of the separating box 1. The separating conveyor belt 5 is installed between the two separating conveyor rollers 29. The separating bucket 23 is fixedly connected to the separating conveyor belt 5 by bolts 30 passing through both. Grooves 301 corresponding to the positions of the bolts 30 are opened on the outer side surfaces of the two separating conveyor rollers 29. When the two separating conveyor rollers 29 drive the separating conveyor belt 5 to rotate, the end of the bolt 30 on the inner side of the separating conveyor belt 5 can enter the groove 301 without affecting the normal operation of the separating conveyor belt 5. During installation, the separating conveyor belt 5 can be installed between the two separating conveyor rollers 29 first, and then multiple separating buckets 23 can be fixedly installed on the outer side surface of the separating conveyor belt 5 in sequence by bolts 30. A separation conveyor motor 31 is fixedly installed on the front side of the separation box 1. The output shaft of the separation conveyor motor 31 is coaxially and fixedly connected to one of the separation conveyor rollers 29. The separation conveyor motor 31 is connected to a power supply and a controller. When started, it can drive the separation conveyor rollers 29 and the separation conveyor belt 5 to rotate. The power supply can be an external power supply or a stored power supply installed on the separation box 1.

[0044] Example 8, as shown in the appendix Figure 5 , Figure 6 , Figure 13 As shown, a mud collection trough 32 runs through the interior of the mud collection box 7 and the separation box 1. A mud collection inclined plate 33, which is lower on the left and higher on the right, is fixedly installed on the bottom surface inside the mud collection box 7. A mud discharge trough 34 located on the left side of the mud collection inclined plate 33 runs through the bottom of the mud collection box 7. The sludge discharge assembly 8 includes a semi-circular groove plate 35 installed below the opening of the sludge discharge trough 34. A sludge discharge pipe 36 coaxial with the semi-circular groove plate 35 and communicating with the interior of the sludge collection box 7 is fixedly installed on the front side of the sludge collection box 7. A sludge discharge auger 37 located inside the semi-circular groove plate 35 and extending into the sludge discharge pipe 36 is rotatably installed on the rear side of the sludge collection box 7. A sludge discharge motor 38 is installed on the rear side of the sludge collection box 7. The sludge discharge motor 38 is connected to a power supply and a controller. The output shaft of the sludge discharge motor 38 is coaxially and fixedly connected to the sludge discharge auger 37. When the sludge in the inner bucket 24 falls downwards, it falls through the sludge collection trough 32 onto the inclined surface of the sludge collection plate 33 and slides down to the left side of the inclined surface to the discharge trough 34, so that the sludge enters the semi-circular trough plate 35. Then, the sludge can be transported to the discharge pipe 36 by the rotating discharge auger 37 and discharged from the front end of the discharge pipe 36. A trolley can be installed on the ground below the discharge pipe 36 to collect the discharged sludge. The trolley can be a manual trolley or a motor vehicle, which moves together with the separation box 1 and is always located below the discharge pipe 36 to receive the discharged sludge.

[0045] Example 9, as shown in the appendix Figures 1-6 , Figure 14 As shown, track rails 39 are installed on the front and rear sides of the separation box 1. Track sliders 40 are slidably installed in each track rail 39. Track brackets 41 are fixedly connected to the side of each track slider 40 away from the separation box 1. Track wheel sets 42 (track wheel sets 42 include multiple track wheels and tracks, which is the prior art and will not be described in detail) are installed on each track bracket 41. A power source for driving track wheel sets 42 is installed on each track bracket 41. By adjusting the height of the track slider 40 within the track rail 39, the height of the track wheel assembly 42 can be adjusted. When it is necessary to move on the ground, the track slider 40 can be moved to the bottom of the track rail 39 so that the bottom surface of the track wheel assembly 42 is lower than the bottom surface of the separation box 1, and the track wheel assembly 42 can drive the separation box 1 to move on the ground. When dredging is required inside a canal, a pad is laid on the canal so that the two track wheel sets 42 are placed on both sides of the canal. Then, the track slider 40 is moved towards the top of the track rail 39 so that the separation box 1 is lowered into the canal and the bottom surface of the separation box 1 is in contact with the bottom surface of the canal. With the adjustable height of the track wheel set 42, the separation box 1 can be used in canals of different depths.

[0046] Example 10, as attached Figure 1 , Figure 4 , Figure 5 , Figure 14 As shown, a height adjustment screw 43 is rotatably mounted between the upper and lower ends of the track slide rail 39. The height adjustment screw 43 passes through the track slider 40 and is threadedly engaged with it. A synchronous sprocket set 44 is installed between the top ends of the two height adjustment screws 43, that is, a sprocket is coaxially fixedly mounted on the top end of each height adjustment screw 43, and a chain is installed between the two sprockets, so that the two height adjustment screws 43 can rotate synchronously. When the height adjustment screw 43 rotates, it can drive the track slider 40 to adjust its height. A height adjustment motor 45 is installed on one of the track slide rails 39. The output shaft of the height adjustment motor 45 is coaxially fixedly connected to one of the height adjustment screws 43. The height adjustment motor 45 is connected to a power supply and a controller. When started, it can drive the two height adjustment screws 43 to rotate synchronously, thereby realizing the height adjustment of the two track wheel sets 42.
