Description

Technical Field

[0001] The present invention relates to the technical field of silt removal equipment, and in particular to silt removal equipment for water conservancy projects and a use method thereof. Background Art

[0002] Water conservancy is a necessary measure and means for agricultural development. In order to increase crop yields and facilitate water use for farmers, irrigation ditches are spread throughout the farmland. As the ditches are used for longer and longer periods of time, debris, aquatic plants, and silt inside the ditches will cause congestion in the ditches, affecting the irrigation of farmland. Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. In water conservancy construction, ditch dredging equipment is often needed to clean the silt in the ditches.

[0003] At present, when dredging farmland irrigation ditches in water conservancy projects, mechanical equipment is generally used to blow and stir the silt deposited on the riverbed into turbid water, which flows away with the river water, thereby playing a role in dredging.

[0017] Preferably, a plurality of adjusting screws are provided on the top of the movable frame, and the adjusting screws are threadedly connected to the first support and the second support.

[0018] The present invention also discloses a method for using a silt removal device for a water conservancy project, comprising the following steps:

[0019] S1: Place the traveling wheels on both sides of the mobile frame on both sides of the water conservancy ditch respectively, and adjust the height of the first support and the second support relative to the mobile frame by rotating the adjusting screw, thereby adjusting the height of the sludge transport mechanism and the crushing and cutting mechanism, so that the bottom end of the material transfer seat of the sludge transport mechanism abuts against the bottom of the ditch, and the position of the lower cutter after moving down abuts against the bottom of the ditch;

[0020] S2: Then the driving motor is controlled to run, the output shaft of the driving motor drives the main bevel gear to rotate, the main bevel gear is meshed with the auxiliary bevel gear 1 and the auxiliary bevel gear 2 on both sides thereof, the auxiliary bevel gear 1 drives the rotating ring to rotate relative to the first support and the barrel, and the auxiliary bevel gear 2 drives the conveying shaft to rotate;

[0021] When the conveying shaft rotates, the rotating rod is driven to rotate through the first synchronous wheel and the first synchronous belt. When the rotating rod rotates, the outer knocking piece rotates synchronously. During the rotation of the knocking piece, the knocking piece counteracts the movement of the force-bearing plate. When the force-bearing plate is stressed, the lower cutter is driven to move downward relative to the connecting seat. The lower cutter crushes the stones deposited at the bottom of the ditch and cuts the compacted silt layer at the bottom of the ditch. When the force-bearing plate is not stressed, it resets and moves upward under the elastic force of the elastic telescopic rod.

[0022] When the rotating ring rotates, it drives the material-discharging seat to rotate. The material-discharging seat displaces the stones crushed by the lower cutter and the cut silt layer. The crushed stones and silt at the bottom of the ditch enter the material trough. As the material-discharging seat rotates, the crushed stones and silt in the material trough slide along the inner wall of the material trough. In this process, part of the water automatically falls along the water leakage hole. The crushed stones and silt layer that slide down with the rotation of the material-discharging seat automatically slide into the feeding port of the barrel.

[0023] When the conveying shaft rotates, the first spiral conveying blade is driven to rotate, and the first spiral conveying blade conveys the crushed stones and sludge entering the barrel;

[0024] S3: The crushed stones and silt in the barrel are transported to the filter barrel by the first spiral conveying blade, and the conveying shaft drives the second spiral conveying blade to continue to transport the crushed stones and silt entering the filter barrel. As the pitch of the second spiral conveying blade gradually decreases, the second spiral conveying blade squeezes the crushed stones and silt during the conveying process, so that the water contained in the silt is squeezed out, and the squeezed water passes through the filter barrel and falls into the liquid guide shell. The water body flows back to the ditch through the inclined guide surface at the bottom of the liquid guide shell. The sludge transported by the second spiral conveying blade is discharged from the discharge end of the filter barrel to the farmland on the side of the ditch, and the crushed stones in the silt are intercepted by the mesh cylinder;

[0025] S4: When the conveying shaft rotates, the second synchronous wheel and the second synchronous belt drive the rotating shaft to rotate. When the rotating shaft rotates, the traveling wheel at the end is driven to rotate, so that the traveling wheel can complete the transfer of silt in the ditch while walking along the ditch, thereby realizing the ditch dredging work.

[0026] Compared with the prior art, the present invention provides a dredging device for water conservancy projects and a method of using the same, which has the following beneficial effects:

[0027] 1. The dredging equipment for water conservancy projects and the method of using the same control the driving mechanism to drive the silt transfer mechanism to work. When the silt transfer mechanism works, the crushing and cutting mechanism is driven to move, so that the silt transfer mechanism cooperates with the crushing and cutting mechanism to cut the silt layer at the bottom of the ditch and then transfer it, so as to facilitate the cleaning of most of the silt in the ditch, avoid the silt from being deposited at the bottom of the ditch again, and ensure the cleaning effect of the water conservancy ditch.

[0028] 2. The dredging equipment for water conservancy projects and the method of using the same can break up the stones deposited at the bottom of the ditch and cut the compacted silt layer at the bottom of the ditch through the crushing and cutting mechanism, so that the silt layers at the bottom of the ditch no longer stick to each other, and reduce the resistance of the material-diverting seat to the silt at the bottom of the ditch when the subsequent silt transfer mechanism works, thereby reducing the difficulty of cleaning the silt at the bottom of the ditch and improving the silt cleaning efficiency. The crushing and cutting mechanism will not stir the silt at the bottom of the ditch on a large scale, so that the material trough of the material-diverting seat can transfer the silt at the bottom of the ditch more completely, and avoid the silt in the ditch from being scattered and flowing with the water, resulting in a large amount of silt being deposited at the bottom of the ditch again in the future.

[0029] 3. The dredging equipment for water conservancy projects and the use method thereof drive the second spiral conveying blade to convey the gravel and silt entering the filter cartridge through the conveying shaft. As the pitch of the second spiral conveying blade gradually decreases, the second spiral conveying blade squeezes the gravel and silt during the conveying process, so that the water contained in the silt is squeezed out, and the squeezed water passes through the filter cartridge and falls into the liquid guide shell. The water body flows back to the ditch through the inclined guide surface at the bottom of the liquid guide shell, so as to avoid a large amount of water in the silt and effectively reduce the water content of the silt. The silt discharged from the filter cartridge is directly discharged to the farmland for soil improvement, which saves manpower and material resources consumed in silt transportation and reduces the cost of dredging. The silt contains nutrient-rich organic matter. As a soil conditioner, it can increase soil fertility, improve soil structure, and improve soil water retention capacity and air permeability, thereby having a positive effect on plant growth and development.

[0030] 4. The dredging equipment for water conservancy projects and the method of using the same, when the sludge transfer mechanism is driven to work by the driving mechanism, the conveying shaft drives the rotating shaft to rotate through the second synchronous wheel and the second synchronous belt, and the rotating shaft drives the traveling wheel at the end to rotate when it rotates, so that the traveling wheel can transfer the sludge in the ditch while walking along the ditch, thereby improving the sludge cleaning efficiency.

[0031] 5. The dredging equipment for water conservancy projects and the method for using the same, by arranging a mesh cylinder at the discharge end of the filter cylinder, intercepts the gravel in the sludge discharged from the filter cylinder to prevent the gravel from falling into the farmland along with the sludge. As the dredging equipment transports the sludge while moving, the mesh cylinder vibrates during the process of collecting the gravel, which accelerates the falling of the sludge from the mesh cylinder and effectively prevents the mesh holes of the mesh cylinder from being blocked, thereby ensuring the sludge discharge speed.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0046] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , a dredging device for water conservancy projects, comprising a mobile frame 1, and also comprising:

[0047] A first support 2, wherein two first supports 2 are provided and are respectively arranged on both sides of the movable frame 1, and a sludge transfer mechanism is provided between the two first supports 2;

[0048] A driving mechanism, which is fixed on the first support 2 and is used to drive the sludge transport mechanism to transport the sludge at the bottom of the ditch;

[0049] The second support 3 is provided with two second supports 3 and respectively arranged on both sides of the movable frame 1, and a crushing and cutting mechanism connected with the sludge transport mechanism is provided between the two second supports 3, which is used for crushing stones in the ditch and cutting the compacted sludge layer at the bottom of the ditch.

[0050] Specifically, the walking wheels 104 on both sides of the mobile frame 1 are respectively placed on both sides of the water conservancy ditch section 17, and the sludge transfer mechanism and the crushing and cutting mechanism are placed in the water body of the ditch. The driving mechanism is controlled to work so that the driving mechanism drives the sludge transfer mechanism to work. When the sludge transfer mechanism works, it drives the crushing and cutting mechanism to move. The crushing and cutting mechanism works on the sludge accumulation layer 18 on the bottom side of the ditch section 17. By crushing the deposited stones and cutting the hardened sludge layer at the bottom of the ditch, the sludge layer at the bottom of the ditch is no longer adhered, thereby reducing the subsequent transportation resistance of the sludge at the bottom of the ditch when the sludge transfer mechanism works, thereby reducing the difficulty of cleaning the sludge at the bottom of the ditch and improving the sludge cleaning efficiency. By cooperating with the sludge transfer mechanism and the crushing and cutting mechanism, the sludge layer at the bottom of the ditch is cut and then transported, which is convenient for cleaning most of the sludge in the ditch, avoiding the sludge from being deposited at the bottom of the ditch again, and ensuring the cleaning effect of the water conservancy ditch.

[0051] Example 2: Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Fig. 9 , a dredging equipment for water conservancy projects, based on Example 1, further, the silt transfer mechanism includes a rotating ring 4 rotatably connected to the two first supports 2 respectively, a material shifting seat 401 is arranged between the two rotating rings 4, the material shifting seat 401 is provided with a material trough 4011 for accommodating silt, and a plurality of water leakage holes 4012 are opened on the material shifting seat 401, a support plate 5 is fixedly provided on the first support 2, a material barrel 501 placed in the rotating ring 4 is fixedly provided on the support plate 5, a feed port 5011 is opened on the top of the material barrel 501, and a material conveying component is arranged in the material barrel 501.

[0052] Furthermore, the material conveying assembly includes a conveying shaft 6 rotatably disposed on the first support 2 , and a first spiral conveying blade 601 is disposed on the conveying shaft 6 .

[0053] Specifically, when the sludge transport mechanism is working, the rotating ring 4 rotates relative to the first support 2 and the barrel 501, and the rotating ring 4 rotates to drive the material shifting seat 401 to rotate. The material shifting seat 401 shifts the stones crushed by the crushing and cutting mechanism and the cut sludge layer, and the crushed stones and sludge at the bottom of the ditch enter the material trough 4011. As the material shifting seat 401 rotates, the crushed stones and sludge in the material trough 4011 slide along the inner wall of the material trough 4011, and in this process, part of the water will automatically fall into the ditch along the leakage hole 4012, and the crushed stones and sludge layer that slide down with the rotation of the material shifting seat 401 will automatically fall into the ditch. It slides in from the feed port 5011 of the barrel 501, and when the conveying shaft 6 rotates, it drives the first spiral conveying blade 601 to rotate, and the first spiral conveying blade 601 transports and discharges the gravel and silt entering the barrel 501; when the sludge transport mechanism works, it drives the crushing and slitting mechanism to operate, and the operation of the sludge transport mechanism and the crushing and slitting mechanism will not stir the silt at the bottom of the ditch on a large scale, so that the material trough 4011 of the material dispensing seat 401 can transfer the silt at the bottom of the ditch more completely, and avoid the silt in the ditch from flowing with the water due to being scattered, resulting in more silt being deposited at the bottom of the ditch again later.

[0054] Example 3: Reference Figure 1-10 , a dredging equipment for water conservancy projects, based on Example 2, further, the driving mechanism includes a driving motor 7 fixedly mounted on the first support 2, the output shaft of the driving motor 7 passes through the first support 2 and is connected to the main bevel gear 701, the rotating ring 4 is provided with a secondary bevel gear 402 meshing with the main bevel gear 701, and the conveying shaft 6 is provided with a secondary bevel gear 603 meshing with the main bevel gear 701.

[0055] Furthermore, a filter cartridge 8 connected to the first support 2 is fixedly provided at one end of the barrel 501, and the conveying shaft 6 is rotatably arranged in the filter cartridge 8. A second spiral conveying blade 602 is arranged on the shaft body of the conveying shaft 6 placed in the filter cartridge 8, and the pitch of the second spiral conveying blade 602 gradually decreases along the axial direction of the conveying shaft 6.

[0056] Furthermore, a liquid guide housing 9 is fixedly provided at the bottom of the filter cartridge 8 , and the bottom of the liquid guide housing 9 is arranged as an inclined guide surface, the high end of the inclined guide surface is arranged at the lower side of the filter cartridge 8 , and a mesh cylinder 16 is arranged at the discharge end of the filter cartridge 8 .

[0057] Specifically, the driving motor 7 is controlled to operate, and the output shaft of the driving motor 7 drives the main bevel gear 701 to rotate. The main bevel gear 701 is respectively meshed with the auxiliary bevel gear 1 402 and the auxiliary bevel gear 2 603 on both sides thereof for transmission. The auxiliary bevel gear 1 402 drives the rotating ring 4 to rotate relative to the first support 2 and the barrel 501, and the auxiliary bevel gear 2 603 drives the conveying shaft 6 to rotate. When the conveying shaft 6 rotates, it drives the first spiral conveying blade 601 to rotate. The first spiral conveying blade 601 conveys the gravel and silt entering the barrel 501, and the gravel and silt in the barrel 501 are conveyed to the filter cartridge 8 through the first spiral conveying blade 601. The conveying shaft 6 drives the second spiral conveying blade 602 to continue conveying the gravel and silt entering the filter cartridge 8. As the pitch of the second spiral conveying blade 602 gradually decreases, the second spiral conveying blade 602 squeezes the gravel and silt during the conveying process, so that the water contained in the silt is squeezed out, and the squeezed water passes through the filter cartridge 8 and falls down. To the liquid guiding shell 9, the water flows back to the ditch through the inclined guiding surface at the bottom of the liquid guiding shell 9, so as to avoid the sludge containing a large amount of water and effectively reduce the moisture content of the sludge. The sludge transported by the second spiral conveying blade 602 is discharged from the discharge end of the filter cartridge 8 to the farmland on the side of the ditch. The sludge discharged from the filter cartridge 8 is directly discharged to the side of the farmland for soil improvement, which saves manpower and material resources consumed in sludge transportation and reduces the cost of dredging. The sludge contains nutrient-rich organic matter. As a soil conditioner, it can increase soil fertility, improve soil structure, and improve soil water retention capacity and air permeability, thereby having a positive effect on the growth and development of plants. The gravel in the sludge is intercepted by the mesh tube 16 to prevent the gravel from falling into the farmland with the sludge. As the dredging equipment transports and cleans the sludge during walking, the mesh tube 16 shakes during the process of collecting the gravel, which accelerates the sludge to fall from the mesh tube 16 and effectively avoids the mesh holes of the mesh tube 16 from being blocked, thereby ensuring the sludge discharge speed.

[0058] Example 4: Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 , a dredging equipment for water conservancy projects, based on Example 3, further, the crushing and cutting mechanism includes a connecting seat 10 arranged between two second supports 3, and a lower cutting knife 11 for crushing stones at the bottom of the ditch and cutting the compacted silt layer at the bottom of the ditch is slidably connected in the connecting seat 10, and a force plate 111 is fixedly provided on the top of the lower cutting knife 11, and an elastic telescopic rod 112 is provided between the force plate 111 and the connecting seat 10, and a rotating rod 12 is also rotatably connected between the two second supports 3, and a knocking piece 121 that is movably opposed to the force plate 111 is provided on the rotating rod 12, and a first synchronous wheel 13 is provided on the rotating rod 12 and the conveying shaft 6, and a first synchronous belt is provided between the two first synchronous wheels 13.

[0059] Specifically, when the driving mechanism is working, the main bevel gear 701 is meshed with the auxiliary bevel gear 603 for transmission, and the auxiliary bevel gear 603 drives the conveying shaft 6 to rotate. When the conveying shaft 6 rotates, the rotating rod 12 is driven to rotate through the first synchronous wheel 13 and the first synchronous belt. When the rotating rod 12 rotates, the outer knocking piece 121 rotates synchronously. During the rotation of the knocking piece 121, it is movable against the force-bearing plate 111. When the force-bearing plate 111 is subjected to force, it drives the lower cutter 11 to move downward relative to the connecting seat 10. The lower cutter 11 crushes the stones deposited at the bottom of the ditch and cuts the compacted silt layer at the bottom of the ditch. When the force-bearing plate 111 is not subjected to force, the elastic force of the elastic telescopic rod 112 Push down to reset and move upward; the crushing and cutting mechanism is used to crush the stones deposited at the bottom of the ditch and cut the compacted silt layer at the bottom of the ditch, so that the silt layers at the bottom of the ditch are no longer adhered to each other, thereby reducing the material removal resistance of the material-moving seat 401 to the silt at the bottom of the ditch when the subsequent silt transfer mechanism works, thereby reducing the difficulty of cleaning the silt at the bottom of the ditch and improving the silt cleaning efficiency; and the crushing and cutting mechanism will not stir the silt at the bottom of the ditch on a large scale, so that the material trough 4011 of the material-moving seat 401 can transfer the silt at the bottom of the ditch more completely, thereby avoiding the silt in the ditch from flowing with the water due to dispersion, resulting in more silt being deposited at the bottom of the ditch again later.

[0060] Example 5: Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 8 and Fig.11 , a dredging equipment for water conservancy projects, based on Example 4, further, the mobile frame 1 includes a frame 101, and two symmetrical ear plates 102 are respectively arranged on the front and rear sides of the frame 101, and a rotating shaft 103 is rotatably arranged between the two ear plates 102, and walking wheels 104 are arranged at both ends of the rotating shaft 103, and second synchronous wheels 14 are arranged on the rotating shaft 103 and the conveying shaft 6, and a second synchronous belt is arranged between the two second synchronous wheels 14.

[0061] Specifically, when the driving assembly drives the conveying shaft 6 to rotate, the conveying shaft 6 drives the rotating shaft 103 to rotate through the second synchronous wheel 14 and the second synchronous belt. When the rotating shaft 103 rotates, it drives the walking wheel 104 at the end to rotate, so that the walking wheel 104 can complete the transfer of silt in the ditch while walking along the ditch, realize the ditch dredging work, and improve the silt cleaning efficiency.

[0062] Example 6: Reference Figure 1 , Figure 3 , Figure 6 and Figure 7 , a dredging equipment for water conservancy projects, based on Example 5, further, a plurality of adjusting screws 15 are arranged on the top of the movable frame 1, and the adjusting screws 15 are threadedly connected with the first support 2 and the second support 3.

[0063] Specifically, an adjusting screw 15 is provided on the movable frame 1. By rotating the adjusting screw 15, the first support 2 and the second support 3 are moved up or down relative to the adjusting screw 15, thereby adjusting the height of the first support 2 and the second support 3 relative to the movable frame 1, and then adjusting the height of the sludge transfer mechanism and the crushing and cutting mechanism, so that the bottom end of the material transfer seat 401 of the sludge transfer mechanism abuts against the bottom of the ditch, and the position of the lower cutter 11 after moving downward abuts against the bottom of the ditch, thereby ensuring the normal progress of the ditch dredging work.

[0064] The present invention also discloses a method for using a dredging device for a water conservancy project, comprising the following steps:

[0065] S1: Place the walking wheels 104 on both sides of the mobile frame 1 on both sides of the water conservancy ditch respectively, and adjust the height of the first support 2 and the second support 3 relative to the mobile frame 1 by rotating the adjusting screw 15, and then adjust the height of the sludge transport mechanism and the crushing and cutting mechanism, so that the bottom end of the material transfer seat 401 of the sludge transport mechanism abuts against the bottom of the ditch, and the position of the lower cutter 11 after moving downward abuts against the bottom of the ditch;

[0066] S2: Then the driving motor 7 is controlled to operate, and the output shaft of the driving motor 7 drives the main bevel gear 701 to rotate. The main bevel gear 701 is respectively meshed with the auxiliary bevel gear 1 402 and the auxiliary bevel gear 2 603 on both sides thereof, and the auxiliary bevel gear 1 402 drives the rotating ring 4 to rotate relative to the first support 2 and the barrel 501, and the auxiliary bevel gear 2 603 drives the conveying shaft 6 to rotate;

[0067] When the conveying shaft 6 rotates, the rotating rod 12 is driven to rotate through the first synchronous wheel 13 and the first synchronous belt. When the rotating rod 12 rotates, the outer knocking piece 121 rotates synchronously. During the rotation of the knocking piece 121, the knocking piece 121 is against the force plate 111. When the force plate 111 is stressed, the lower cutter 11 is driven to move downward relative to the connecting seat 10. The lower cutter 11 crushes the stones deposited at the bottom of the ditch and cuts the silt layer compacted at the bottom of the ditch. When the force plate 111 is not stressed, it is pushed back to the upper position by the elastic force of the elastic telescopic rod 112.

[0068] When the rotating ring 4 rotates, it drives the material-dispensing seat 401 to rotate. The material-dispensing seat 401 shifts the stones and the silt layer that have been broken by the lower cutter 11. The broken stones and silt at the bottom of the ditch enter the material trough 4011. As the material-dispensing seat 401 rotates, the broken stones and silt in the material trough 4011 slide along the inner wall of the material trough 4011. In this process, part of the water automatically falls along the water leakage hole 4012. The broken stones and silt layer that slide down along with the rotation of the material-dispensing seat 401 automatically slide into the feeding port 5011 of the barrel 501.

[0069] When the conveying shaft 6 rotates, the first spiral conveying blade 601 is driven to rotate, and the first spiral conveying blade 601 conveys the gravel and sludge entering the barrel 501;

[0070] S3: The crushed stones and silt in the barrel 501 are transported to the filter barrel 8 by the first spiral conveying blade 601, and the conveying shaft 6 drives the second spiral conveying blade 602 to continue to transport the crushed stones and silt entering the filter barrel 8. As the pitch of the second spiral conveying blade 602 gradually decreases, the second spiral conveying blade 602 squeezes the crushed stones and silt during the conveying process, so that the water contained in the silt is squeezed out, and the squeezed water passes through the filter barrel 8 and falls into the liquid guide housing 9. The water body flows back to the ditch through the inclined guide surface at the bottom of the liquid guide housing 9. The sludge transported by the second spiral conveying blade 602 is discharged from the discharge end of the filter barrel 8 to the farmland on the side of the ditch, and the crushed stones in the silt are intercepted by the mesh cylinder 16;

The main bevel gear (701) is respectively meshed with the auxiliary bevel gear 1 (402) and the auxiliary bevel gear 2 (603) on both sides thereof for transmission. The auxiliary bevel gear 1 (402) drives the rotating ring (4) to rotate relative to the first support (2) and the barrel (501), and the auxiliary bevel gear 2 (603) drives the conveying shaft (6) to rotate; When the conveying shaft (6) rotates, the rotating rod (12) is driven to rotate through the first synchronous wheel (13) and the first synchronous belt. When the rotating rod (12) rotates, the outer knocking piece (121) rotates synchronously. During the rotation of the knocking piece (121), the knocking piece (121) is moved against the force plate (111). When the force plate (111) is subjected to force, the lower cutter (11) is driven to move downward relative to the connecting seat (10). The lower cutter (11) crushes the stones deposited at the bottom of the ditch and cuts the silt layer compacted at the bottom of the ditch. When the force plate (111) is not subjected to force, it is pushed back to the original position and moves upward under the elastic force of the elastic telescopic rod (112). When the rotating ring (4) rotates, it drives the material shifting seat (401) to rotate. The material shifting seat (401) shifts the stones and the silt layer that have been broken by the lower cutter (11). The broken stones and silt at the bottom of the ditch enter the material trough (4011). As the material shifting seat (401) rotates, the broken stones and silt in the material trough (4011) slide along the inner wall of the material trough (4011). In this process, part of the water automatically falls along the water leakage hole (4012). As the material shifting seat (401) rotates, the broken stones and silt layer that slide down automatically slide into the material inlet (5011) of the barrel (501). When the conveying shaft (6) rotates, the first spiral conveying blade (601) is driven to rotate, and the first spiral conveying blade (601) conveys the crushed stones and sludge entering the barrel (501); S3: the crushed stones and silt in the barrel (501) are transported to the filter barrel (8) by the first spiral transport blade (601), and the transport shaft (6) drives the second spiral transport blade (602) to continue to transport the crushed stones and silt entering the filter barrel (8). As the pitch of the second spiral transport blade (602) gradually decreases, the second spiral transport blade (602) squeezes the crushed stones and silt during the transport process, so that the water contained in the silt is squeezed out. The squeezed water passes through the filter barrel (8) and falls into the liquid guide housing (9). The water flows back into the ditch through the inclined guide surface at the bottom of the liquid guide housing (9). The sludge transported by the second spiral transport blade (602) is discharged from the discharge end of the filter barrel (8) to the farmland on the side of the ditch, and the crushed stones in the silt are intercepted by the net barrel (16); S4: When the conveying shaft (6) rotates, the second synchronous wheel (14) and the second synchronous belt drive the rotating shaft (103) to rotate. When the rotating shaft (103) rotates, the running wheel (104) at the end is driven to rotate, so that the running wheel (104) can complete the transportation of silt in the ditch while walking along the ditch, thereby achieving ditch desilting work.
