Description

Technical Field

[0001] This invention relates to the technical field of water conservancy construction facilities, and in particular to a device for backfilling, spreading and compacting earthwork for river management. Background Technology

[0002] In water conservancy projects, river management typically involves using mechanical equipment to lift up silt deposited at the bottom of the river, allowing it to flow away with the water and thus clearing the river channel. During the river management process, low-lying areas on both sides of the river, as well as potholes created when clearing shrubs and weeds along the riverbank, all need to be backfilled and repaired.

[0003] Related technology can be found in Chinese Patent No. CN114718136B, which discloses a backfilling device and method for water conservancy construction. The device includes a left shell, guide rails, a right shell, guide grooves, an upper smooth rod, a lower smooth rod, a transmission smooth rod, a support shaft, a lower sliding seat, a brake motor, a transmission gear, a middle dovetail guide rail, a middle dovetail seat, a transmission rack, a bamboo-joint tube, a screening section, and a compaction section. Two horizontal guide rails are fixed at each end of the inner wall of the left shell. The right shell is installed on the right side of the left shell, and guide grooves are provided at both the front and rear ends of the right shell. This invention can simultaneously screen, uniformly backfill, and synchronously compact earthwork. By controlling the rotation of the speed-regulating motor, the circumferential movement of the screening rod can be indirectly achieved, thereby screening the earthwork under centrifugal force. The screened soil, guided by the guide plate, falls relatively evenly to both sides of the pipe, thus reducing the radial pressure difference of the pipe and preventing large radial displacement.

[0004] Regarding the aforementioned technologies, a speed-regulating motor drives a screening rod to screen stones or soil clods of different sizes. However, the crushing effect is not good for some larger diameter soil clods. When the diameter of the soil clod is larger than the maximum gap between adjacent screening rods, the soil clod is easy to get stuck between the screening rods. If manual or mechanical equipment is used to crush the large diameter soil clods in advance, it will take a certain amount of time and manpower, which can easily affect the efficiency of earthwork backfilling. Summary of the Invention

[0005] To reduce the probability of large-diameter soil clods affecting the screening of soil by the screen assembly, streamline the workflow, and improve the efficiency of earthwork backfilling.

[0006] This application provides a soil backfilling, spreading, and compaction device for river channel management, which adopts the following technical solution: A soil backfilling, spreading, and compaction device for river channel management includes a chassis with a drive wheel at the lower end for moving the chassis. The chassis includes a crushing assembly comprising a baffle plate, an extrusion plate, an elastic element, a drive component, and a connecting hook. A hopper is fixedly mounted at the upper end of the chassis, and a support plate is mounted at the lower end of the hopper. The baffle plate is located inside the hopper and abuts against the upper end of the support plate. An installation chamber is fixedly mounted in the hopper, and the baffle plate is located in the installation chamber and slidably connected to the hopper. A clearance chamber is fixedly mounted in the hopper, directly opposite the installation chamber. The extrusion plate is located inside the clearance chamber and slidably connected to the clearance chamber. An opening at the lower end of the clearance chamber connects the hopper and the chassis. The elastic element is located on the baffle plate away from the extrusion plate. On one side, when the elastic element is in a stretched state, it tends to move the stop plate away from the extrusion plate. The driving element is located on the side of the machine box near the extrusion plate, used to move the extrusion plate closer to or away from the stop plate. The connecting hook is fixedly connected to the side of the extrusion plate near the stop plate. A straight plate is vertically fixedly connected to the side of the stop plate near the extrusion plate. The straight plate has a slot that matches the connecting hook. The connecting hook engages with the slot. The screen assembly is located at the lower end of the crushing assembly and is directly opposite the lower end of the hopper. The screen assembly is movably connected to the machine box. The machine box is equipped with a vibration motor for driving the screen assembly to vibrate. The tamping plate is slidably connected to the machine box in the vertical direction. The machine box is equipped with a lifting motor for driving the tamping plate to move in the vertical direction.

[0007] By adopting the above technical solution, the drive wheel improves the convenience of moving the machine box. The machine box is placed on the upper end of the pit to be filled, and soil is filled into the hopper. As the soil enters the hopper, it accumulates on the upper end of the support plate. Initially, the sides of the baffle plate and the extrusion plate are flush with the inner wall of the hopper. Under the limiting action of the clearance chamber, the drive component moves the extrusion plate closer to the baffle plate. The hopper limits the baffle plate through the installation chamber, allowing the extrusion plate and baffle plate to cooperate in extruding and crushing the soil. After extrusion, the drive component moves the extrusion plate away from the baffle plate. As the extrusion plate moves, the connecting hook and slot work together to move the straight plate, which in turn moves the baffle plate and extrusion plate synchronously. At this time, the elastic element is in a stretched state. When the baffle plate moves, it pushes the soil on the support plate into the screen assembly through the opening of the clearance chamber. A vibrating motor drives a vibrating screen to sieve the soil. The sieved soil falls into a pit, and finally, a lifting motor drives a compaction plate to compact the soil. After the soil on the support plate is cleared, when the drive unit moves the extrusion plate to reset, the stop plate resets under the action of the elastic element, and the soil in the hopper continues to flow between the stop plate and the extrusion plate, awaiting the next extrusion process. By using a crushing component to crush large-diameter soil clods, the probability of large-diameter soil clods affecting the sieve assembly is reduced, thus improving the efficiency of earthwork backfilling.

[0008] Optionally, the extrusion plate has several partition plates along its length on the side near the stop plate. The extrusion plate has several positioning grooves that are adapted to the partition plates. The partition plates are inserted into the corresponding positioning grooves and fit against the inner wall of the positioning grooves. The upper end of the extrusion plate is provided with a cover plate. The upper end surface of all the partition plates abuts against the lower end surface of the cover plate. The cover plate is provided with several countersunk bolts. The countersunk bolts pass through the cover plate and are threadedly connected to the extrusion plate.

[0009] By adopting the above technical solution, the countersunk bolts cooperate with the extrusion plate to position the cover plate, and then the cover plate and extrusion plate cooperate to position all the partition plates. When the extrusion plate moves, it drives the partition plates to move, which cuts the soil clods and improves the crushing effect. By removing the cover plate, the partition plates can be easily removed from the positioning slots, which makes it easy to adjust the spacing between adjacent partition plates and thus facilitates the crushing of soil clods of different diameters.

[0010] Optionally, the drive component one includes a motor one, a rotating wheel, a swing arm, and a push rod. The push rod is vertically fixed to the side of the extrusion plate away from the stop plate. The swing arm is located inside the housing and is rotatably connected to the housing in the vertical direction. A sliding groove one is opened vertically at the upper end of the swing arm. A cylinder is vertically fixed at the end of the push rod away from the extrusion plate. The cylinder is inserted into the sliding groove one and is slidably connected to the swing arm along the length of the sliding groove one. The motor one is installed inside the housing. The rotating wheel is coaxially fixed with the output shaft of the motor one. A sliding groove two is opened at the lower end of the swing arm along the length direction. A rotating column is fixedly connected to the side of the rotating wheel away from the motor one. The rotating column is inserted into the sliding groove two and is slidably connected to the swing arm along the length of the sliding groove two.

[0011] By adopting the above technical solution, motor one drives the rotating wheel to rotate. Under the cooperation of the rotating column and the sliding groove two, the rotating wheel drives the swing arm to swing. Under the cooperation of the cylinder and the sliding groove one, the swing arm drives the push rod to move along the length direction, and then drives the extrusion plate to move closer to or away from the stop plate through the push rod.

[0012] Optionally, a lifting platform is slidably connected vertically inside the chassis. The chassis has a vertically opening moving slot. A trapezoidal block adapted to the moving slot is fixedly connected to the lifting platform. The trapezoidal block is located inside the moving slot and is slidably connected to the chassis vertically. Motor 1 is fixedly connected to the upper end of the lifting platform. Motor 2 is fixedly installed in the chassis. A threaded rod is coaxially fixed to the output shaft of Motor 2. The threaded rod is arranged along the length direction of the moving slot. The threaded rod passes through the trapezoidal block and is threadedly connected to the trapezoidal block.

[0013] By adopting the above technical solution, motor 2 drives the threaded rod to rotate. Under the limiting effect of the moving slot on the trapezoidal block, the rotation of the threaded rod drives the lifting platform to move vertically through the trapezoidal block. When the lifting platform moves, it drives motor 1 to move. When motor 1 moves closer to the connection point of the swing arm with the machine box, the swing amplitude of the swing arm increases when the wheel rotates, which in turn reduces the minimum distance when the extrusion plate moves closer to the stop plate, thereby improving the crushing effect on the soil clods. When motor 1 moves further away from the connection point of the swing arm with the frame, the swing amplitude of the swing arm decreases, and the crushing effect on the soil clods decreases.

[0014] Optionally, the screen assembly includes a vibrating plate, a first annular screen, a second annular screen, and a rotating motor. The housing has a receiving groove adapted to the vibrating plate, which is located within the receiving groove. Several connecting springs are fixedly installed on both the upper and lower ends of the vibrating plate. The connecting springs are arranged circumferentially around the vibrating plate, and the ends of all connecting springs away from the vibrating plate are fixedly connected to the housing. The vibrating motor is fixedly connected to the upper end of the vibrating plate. The vibrating plate has a vertically open mounting hole, and both the first and second annular screens are located within the mounting hole. The first annular screen is located at the upper end of the second annular screen and is fixedly connected to the vibrating plate. The second annular screen is rotatably connected to the vibrating plate circumferentially. The rotating motor is located at the lower end of the vibrating plate. A gear is coaxially fixed to the output shaft of the rotating motor, and several toothed blocks that mesh with the gear are fixedly connected circumferentially to the second annular screen.

[0015] By adopting the above technical solution, the vibrating plate moves within the receiving groove under the action of all connecting springs. The vibrating plate is driven to vibrate by the vibration motor, thereby enabling the annular screen one and annular screen two to cooperate in screening the soil. By rotating the motor, the gears are driven to rotate. Under the meshing action of the gears and tooth blocks, the rotation of the gears drives the annular screen two to rotate. When the annular screen two rotates at different angles, the diameter of the screen holes that connect the annular screen one and the annular screen two changes, thus facilitating the adjustment of the screening effect of the screen assembly.

[0016] Optionally, the chassis has material inlets on both sides along its width, located between the vibration component and the hopper. The chassis is hinged with a baffle adapted to the material inlets, which opens and closes towards the inside of the chassis. The baffle is made of transparent material.

[0017] By adopting the above technical solution, the working condition of the screen assembly can be easily observed through the baffle. When stones or garbage get stuck on the first ring screen, the baffle can be flipped over, and the first ring screen can be cleaned through the material inlet, making it relatively convenient to clean the first ring screen.

[0018] Optionally, the lower end of the chassis is rotatably connected to two sets of receiving plates, both of which are located below the vibrating plate. Each set of receiving plates has a sliding groove on the side closest to each other, and the receiving plates are provided with moving plates adapted to the sliding grooves. The chassis has a horizontal groove, and the moving plate is rotatably connected to a moving wheel adapted to the horizontal groove at a position away from the receiving plate. The moving wheel is located in the horizontal groove and is slidably connected to the chassis along the length of the horizontal groove. The lower end of the chassis is rotatably connected to a push cylinder corresponding to each receiving plate, and the output end of the push cylinder is fixedly connected to a moving block, which is hinged to the moving plate.

[0019] By adopting the above technical solution, the soil sieved by the screen assembly falls onto the receiving plate under the action of gravity, slides along the receiving plate towards the moving plate, and finally slides into the pit through the gap between the two moving plates. By pushing the cylinder to move the moving block, the moving block drives the moving plate to move. Under the limiting action of the transverse groove on the moving wheel, the moving plate moves along the length of the sliding groove, thus keeping the moving plate and the corresponding receiving plate on the same plane. When the moving plate moves, it causes the soil to slide into different areas, thereby facilitating the adjustment of the soil filling position.

[0020] Optionally, the tamping plate includes a lifting plate and two auxiliary plates. The lifting plate is located between the two auxiliary plates, and both the lifting plate and the two auxiliary plates are slidably connected to the machine box in the vertical direction. The lifting motor is used to drive the lifting plate to move in the vertical direction. The two ends of the lower end of the lifting plate are fixedly connected to top blocks in the length direction. The auxiliary plates have grooves that are adapted to the top blocks. The top blocks are located in the corresponding grooves and fit against the inner wall of the grooves.

[0021] By adopting the above technical solution, under the combined action of the top block and the groove, the lifting plate moves upward, driving the two auxiliary plates to move. When the lifting plate falls, the auxiliary plates fall synchronously under the action of gravity. The lifting plate and the two auxiliary plates work together to compact the soil. When the width of the pit is less than the width between the two auxiliary plates, the lower end face of the auxiliary plate abuts against the ground around the pit, and the lifting plate continues to fall, thereby completing the compaction of the soil in the pit.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive wheels improve the ease of moving the machine casing. The casing is placed on top of the pit to be filled, and soil is poured into the hopper. As the soil enters the hopper, it accumulates on the upper part of the support plate. Initially, the sides of the baffle plate and the extrusion plate are flush with the inner wall of the hopper. Under the limiting action of the clearance chamber, the drive unit moves the extrusion plate closer to the baffle plate. The hopper, through the mounting chamber, limits the baffle plate, allowing the extrusion plate and baffle plate to cooperate in extruding and crushing the soil. After extrusion, the drive unit moves the extrusion plate away from the baffle plate. As the extrusion plate moves, the connecting hook and slot work together to move the straight plate, which in turn moves the baffle plate and extrusion plate synchronously. At this time, the elastic element is in a stretched state. As the baffle plate moves, it pushes the soil on the support plate into the screen assembly through the clearance chamber opening. The vibrating motor drives the vibrating screen to screen the soil. The screened soil falls into the pit, and finally, the lifting motor drives the compaction plate to compact the soil. After the soil on the support plate is cleared, when the drive unit moves the extrusion plate to reset, the stop plate resets under the action of the elastic element, and the soil in the hopper continues to enter between the stop plate and the extrusion plate, waiting for the next extrusion process. By extruding large-diameter soil clods through the crushing component, the probability of large-diameter soil clods affecting the screening of soil by the screen component is reduced, thereby improving the efficiency of earthwork backfilling. 2. Motor 1 drives the rotating wheel to rotate. Under the cooperation of the rotating column and the sliding groove 2, the rotating wheel drives the swing arm to swing. Under the cooperation of the cylinder and the sliding groove 1, the swing arm drives the push rod to move along the length direction, and then drives the extrusion plate to move closer to or away from the stop plate through the push rod; 3. The vibrating plate moves within the receiving groove under the action of all connecting springs. A vibrating motor drives the vibrating plate to vibrate, causing the first and second annular screens to work together to screen the soil. The rotating motor drives the gears to rotate. The meshing of the gears and gear blocks causes the second annular screen to rotate. As the second annular screen rotates at different angles, the diameter of the interconnected screen holes changes, thus facilitating the adjustment of the screening effect of the screen assembly.

Detailed Implementation

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses an earthwork backfilling, spreading, and compaction device for river channel management.

[0033] Example 1 Reference Figure 1 and Figure 2 A soil backfilling, spreading, and compaction device for river channel management includes a rectangular, hollow housing 1. Drive wheels 11 are installed at the lower end of the housing 1, allowing the operator to move the housing 1 using the drive wheels 11. When backfilling is required, the operator moves the housing 1 directly above the pit.

[0034] Reference Figure 1 and Figure 2A hopper 12 is installed at the upper end of the casing 1. The operator adds soil to be backfilled into the casing 1 through the hopper 12. A support plate 14 is fixed inside the casing 1. The support plate 14 is located at the lower end of the hopper 12, and the upper end face of the support plate 14 abuts against the lower end face of the hopper 12. Under the action of gravity, the soil slides down the hopper 12 to the end of the support plate 14, at which point the support plate 14 prevents the soil from falling further.

[0035] Reference Figure 2 and Figure 3 The machine housing 1 contains a crushing assembly 2, which includes a baffle plate 21, a pressing plate 22, an elastic element 23, a driving element 24, and a connecting hook 25. A feeding hopper 12 is fixed with an installation chamber 131, which is arranged laterally and communicates with the feeding hopper 12. The baffle plate 21 is located within the installation chamber 131 and abuts against the inner wall of the installation chamber 131. At this time, the lower end of the baffle plate 21 abuts against the upper end of the support plate 14. The installation chamber 131 limits the movement of the baffle plate 21, allowing it to slide along the length of the support plate 14.

[0036] Reference Figure 2 and Figure 3 The hopper 12 is also fixed with a relief chamber 132. The relief chamber 132 and the mounting chamber 131 are symmetrically arranged with the hopper 12 as the center. The extrusion plate 22 is located in the relief chamber 132 and abuts against the inner wall of the relief chamber 132. The elastic element 23 is installed in the mounting chamber 131 and is located on the side of the stop plate 21 away from the extrusion plate 22. The elastic element 23 is a spring, one end of which is fixedly connected to the stop plate 21 and the other end is fixedly connected to the mounting chamber 131. When the spring is in a stretched state, it has the tendency to drive the stop plate 21 to move away from the relief chamber 132.

[0037] Reference Figure 2 and Figure 3 Under the limiting action of the clearance chamber 132, the extrusion plate 22 and the stop plate 21 are parallel to each other. The connecting hook 25 is located between the extrusion plate 22 and the stop plate 21, and is fixedly connected to the extrusion plate 22, extending along the extrusion plate 22 towards the stop plate 21. The stop plate 21 is fixed with a straight plate 211 corresponding to the connecting hook 25. The straight plate 211 has a slot 212 adapted to the connecting hook 25 along its length direction. The slot 212 extends from the extrusion plate 22 towards the stop plate 21. The end of the connecting hook 25 away from the extrusion plate 22 is inserted into the slot 212 and is slidably connected to the straight plate 211 along the length direction of the slot 212.

[0038] Reference Figure 2 and Figure 4The drive component 24 is located on the side of the extrusion plate 22 away from the stop plate 21. The drive component 24 includes a motor 241, a rotating wheel 242, a swing arm 243, and a push rod 244. A lifting plate is provided inside the housing 1, located on the side of the extrusion plate 22 opposite to the stop plate 21. The motor 241 is mounted on the upper end of the lifting plate. The rotating wheel 242 is coaxially fixed to the output shaft of the motor 241, and the operator manipulates the motor 241 to drive the rotating wheel 242 to rotate. One end of the swing arm 243 along its length is rotatably connected to the housing 1, and the swing arm 243 is perpendicular to the axis of the rotating wheel 242.

[0039] Reference Figure 2 and Figure 4 The swing arm 243 has a second groove 248 extending along its length near the connection point with the chassis 1. A rotating column 246 is fixed to the side of the wheel 242 near the swing arm 243. The rotating column 246 is eccentrically positioned, and its movement is caused by the rotation of the wheel 242. The rotating column 246 is inserted into the second groove 248 and slidably connected to the swing arm 243 along the length of the groove 248. Therefore, as the rotating column 246 moves, it pushes the swing arm 243 to swing around its connection point with the chassis 1.

[0040] Reference Figure 2 and Figure 4 A sliding groove 247 is provided on the swing arm 243 at a position away from the connection with the chassis 1. The sliding groove 247 is parallel to the sliding groove 248. The push rod 244 passes through the clearance chamber 132 and is vertically fixed to the side of the extrusion plate 22 away from the stop plate 21. A cylinder 245 is fixed to the end of the push rod 244 away from the extrusion plate 22. The cylinder 245 is perpendicular to the push rod 244 and inserted into the sliding groove 247. The cylinder 245 is slidably connected to the swing arm 243 along the length of the sliding groove 247. When the swing arm 243 swings, it drives the cylinder 245 to move, which in turn drives the push rod 244 to move along the length of the push rod 244.

[0041] Reference Figure 2 and Figure 3 In the initial state, the end faces of the extrusion plate 22 and the baffle plate 21 that are close to each other are flush with the inner wall of the hopper 12. At this time, the soil is located between the extrusion plate 22 and the baffle plate 21. When the swing rod 243 swings towards the baffle plate 21, it drives the extrusion plate 22 to move closer to the baffle plate 21 through the push rod 244. When the extrusion plate 22 moves closer to the baffle plate 21, it cooperates with the baffle plate 21 to extrude soil clods, thereby crushing large-diameter soil clods. When the extrusion plate 22 moves, it drives the connecting hook 25 to move, causing the connecting hook 25 to move closer to the baffle plate 21 along the slot 212.

[0042] Reference Figure 2 and Figure 3When the swing arm 243 swings away from the stop plate 21, the pressing plate 22 drives the connecting hook 25 to move away from the stop plate 21. When the connecting hook 25 moves to the end of the slot 212 away from the stop plate 21, it abuts against the straight plate 211, thereby driving the straight plate 211 to move away from the installation chamber 131. When the straight plate 211 moves, it drives the stop plate 21 to move closer to the clearance chamber 132. When the stop plate 21 moves, it drives the elastic element 23 to stretch and pushes the soil on the support plate 14 to move towards the clearance chamber 132. The clearance chamber 132 has an opening at its lower end, which is connected to the housing 1. The soil falls into the housing 1 along the opening under the push of the stop plate 21.

[0043] Reference Figure 2 and Figure 3 When the baffle plate 21 moves toward the clearance chamber 132, the soil in the hopper 12 comes into contact with the upper surface of the baffle plate 21. At this time, the baffle plate 21 prevents the soil from entering between the baffle plate 21 and the extrusion plate 22. When the swing rod 243 swings again toward the baffle plate 21, it drives the extrusion plate 22 to reset. At this time, the baffle plate 21 enters the installation chamber 131 under the action of the elastic element 23. When the baffle plate 21 resets, the soil in the hopper 12 continues to fall between the baffle plate 21 and the extrusion plate 22, thereby realizing the cyclic processing of the soil by the extrusion plate 22 and the baffle plate 21.

[0044] Reference Figure 2 and Figure 3 The extrusion plate 22 has multiple sets of partition plates 26 on the side near the stop plate 21. The extrusion plate 22 has multiple positioning slots 221 that fit the partition plates 26. The partition plates 26 are evenly arranged along the length of the extrusion plate 22 and inserted into the corresponding positioning slots 221. The extrusion plate 22 limits the lateral displacement of the partition plates 26 through the positioning plates, so that when the extrusion plate 22 moves, it drives the partition plates 26 to shear the soil, which is beneficial to improving the crushing effect of the extrusion plate 22. By inserting the partition plates 26 into different positioning plates, it is easy to adjust the spacing between adjacent partition plates 26 and adjust the shearing range of the partition plates 26.

[0045] Reference Figure 2 and Figure 3 The upper end of the extrusion plate 22 is provided with a cover plate 27. The upper ends of all the partition plates 26 abut against the lower end face of the cover plate 27. The upper end of the cover plate 27 is provided with multiple countersunk bolts 271. The countersunk bolts 271 are threaded through the cover plate 27 and the extrusion plate 22, so that the countersunk bolts 271 and the extrusion plate 22 cooperate to position the cover plate 27. The cover plate 27 and the extrusion plate 22 cooperate to limit the vertical displacement of all the partition plates 26, which helps to improve the connection stability between the partition plates 26 and the extrusion plate 22.

[0046] Reference Figure 2 and Figure 4A trapezoidal block 151 is fixed to the lifting platform 15. A vertically oriented sliding groove 16 is provided in the housing 1. The trapezoidal block 151 is inserted into the sliding groove 16 and fits against its inner wall. Under the limiting action of the sliding groove 16, the trapezoidal block 151 drives the lifting platform 15 to slide vertically. A threaded rod 161 is rotatably connected to the housing 1. The threaded rod 161 is arranged along the length of the sliding groove 16, passes through the trapezoidal block 151, and is threadedly connected to it. A motor 162 is installed in the housing 1 to drive the threaded rod 161 to rotate. Under the limiting action of the sliding groove 16 on the trapezoidal block 151, the rotation of the threaded rod 161 drives the trapezoidal block 151 to move along the sliding groove 16. The movement of the trapezoidal block 151 drives the lifting platform 15 to move, which in turn drives the motor 241 to move vertically.

[0047] Reference Figure 2 and Figure 4 When motor 241 moves, it drives cylinder 245 to move via wheel 242. When cylinder 245 moves closer to chute 247, the swing amplitude of swing arm 243 decreases, and the moving range of extrusion plate 22 decreases, thus reducing the extrusion effect of extrusion plate 22 on the soil. When cylinder 245 moves away from chute 247, the swing amplitude of swing arm 243 increases, and the moving range of extrusion plate 22 expands, thereby improving the extrusion effect of extrusion plate 22. By adjusting the position of lifting platform 15, the processing range of extrusion plate 22 can be adjusted, which helps to improve the applicability of extrusion plate 22.

[0048] Reference Figure 5 and Figure 6 The chassis 1 is also equipped with a screen assembly 3 (see reference). Figure 2 ), Screen assembly 3 (reference) Figure 2 Located at the lower end of the hopper 12, the screen assembly 3 (reference) Figure 2 The system includes a vibrating plate 31, a first annular screen 32, a second annular screen 33, and a rotating motor 34. A receiving groove 17 is provided circumferentially inside the housing 1, and the vibrating plate 31 is located within the receiving groove 17 and is movably connected to the housing 1. Multiple connecting springs 311 are fixed to both the upper and lower end faces of the vibrating plate 31, and all connecting springs 311 are arranged circumferentially around the vibrating plate 31. A vibration motor 30 (see reference) is provided inside the housing 1. Figure 2 ), vibration motor 30 (reference) Figure 2 The vibration motor 30 (reference) is installed on the upper end of the vibrating plate 31. Figure 2 When in operation, it causes the vibrating plate 31 to sway within the receiving groove 17.

[0049] Reference Figure 2 and Figure 5The vibrating plate 31 has an installation hole 312, which is directly opposite the opening of the installation chamber 131. Soil falling from the opening falls into the installation hole 312. Both annular screen 32 and annular screen 33 are located within the installation hole 312 and are fitted to the inner wall of the hole. Annular screen 32 is located at the upper end of annular screen 33 and is fixedly connected to the vibrating plate 31. When the vibrating plate 31 vibrates, it drives annular screen 32 to vibrate. Soil falls into the upper end of annular screen 32 under gravity, and the vibration of annular screen 32 screens the soil.

[0050] Reference Figure 2 and Figure 5 The second annular screen 33 is rotatably connected to the vibrating plate 31. When the second annular screen 33 is directly opposite the first annular screen 32, the screen holes of the first annular screen 32 and the second annular screen 33 are directly opposite each other. At this time, the diameter of the soil clods passing through the first annular screen 32 and the second annular screen 33 is the largest. When there is a certain angle between the first annular screen 32 and the second annular screen 33, the diameter of the soil clods passing through the first annular screen 32 and the second annular screen 33 is smaller. The rotating motor 34 is installed at the lower end of the vibrating plate 31, and the output shaft of the rotating motor 34 is coaxially fixed with a gear 341. The operator operates the rotating motor 34 to drive the gear 341 to rotate. The second annular screen 33 has multiple evenly arranged gears 341 fixed circumferentially. The tooth blocks 331 all mesh with the gears 341. When the gears 341 rotate, they drive the second annular screen 33 to rotate through the tooth blocks 331, which facilitates the adjustment of the angle between the first annular screen 32 and the second annular screen 33, and helps to improve the applicability of the screen assembly 3.

[0051] Reference Figure 1 and Figure 2 The machine housing 1 has material inlets 18 on both sides along its width. These inlets 18 are located between the screen assembly 3 and the hopper 12. When soil containing stones, plant roots, or debris that cannot easily pass through the first and second annular screens 32 and 33, the operator can use the material inlets 18 to remove the debris from the first annular screen 32, improving the ease of use of the vibrating assembly. The machine housing 1 is hinged with a baffle 181 that matches the material inlets 18. The baffle 181 opens inwards towards the housing door, reducing the probability of soil spilling out of the machine housing 1 during vibrating screening. The baffle 181 is made of a transparent material, such as acrylic, allowing the operator to easily observe the screening process of the screen assembly 3.

[0052] Reference Figure 2 and Figure 7The lower end of the housing 1 is provided with two sets of receiving plates 19. The receiving plates 19 are both located at the lower end of the screen assembly 3, and the sides of the two sets of receiving plates 19 that are far apart from each other are rotatably connected to the housing 1. The sides of the receiving plates 19 that are far away from the hinge point with the housing 1 are inclined downwards. The sides of the two sets of receiving plates 19 that are close to each other form a guide opening. After the soil screened by the screen assembly 3 comes into contact with the receiving plates 19, it slides down the receiving plates 19 towards the guide opening.

[0053] Reference Figure 2 and Figure 7 Each of the two sets of receiving plates 19 has a sliding groove 191 on one side close to each other. Each receiving plate 19 has a movable plate 192 adapted to the sliding groove 191. The movable plate 192 is inserted into the sliding groove 191 and abuts against the receiving plate 19. Under the limiting effect of the sliding groove 191 on the movable plate 192, the rotating receiving plate 19 drives the movable plate 192 to rotate. A movable wheel 193 is rotatably connected to the movable plate 192 away from the receiving plate 19. When the movable plate 192 moves, it drives the movable wheel 193 to swing. The chassis 1 has a horizontal groove 194 adapted to the movable wheel 193. The movable wheel 193 is located in the horizontal groove 194 and is in rolling contact with the inner wall of the horizontal groove 194.

[0054] Reference Figure 2 and Figure 7 The housing 1 limits the movement of the caster 193 via the transverse groove 194. When the moving plate 192 swings, it drives the caster 193 to move along the length of the transverse groove 194. At this time, under the limiting action of the transverse groove 194, the two moving plates 192 move along the sliding groove 191 while swinging. At this time, the lower ends of the two sets of moving plates 192 are kept at the same horizontal plane as the transverse groove 194. The lower end of the housing 1 is equipped with a push cylinder 195 corresponding to the moving plate 192. The output end of the push cylinder 195 is fixedly connected to a moving block 196. The operator manipulates the push cylinder 195 to drive the moving block 196 to move. The moving block 196 is rotatably connected to the corresponding moving plate 192. When the moving block 196 moves, it drives the moving plate 192 to move, which facilitates the adjustment of the distance between the two moving plates 192, and thus the adjustment of the position of the guide port, which facilitates the adjustment of the soil filling position.

[0055] Reference Figure 1 and Figure 2 The chassis 1 has a tamping plate 4 at one end along its length. A mounting box adapted to the tamping plate 4 is fixed to the chassis 1. The tamping plate 4 includes a lifting plate 41 and two auxiliary plates 42. A lifting block is fixedly connected to the lifting plate 41, and a limiting block is fixedly connected to the auxiliary plates 42. The mounting box has a lifting groove adapted to the lifting block and a vertical groove adapted to the limiting block. The lifting groove and the vertical groove are parallel to each other. The lifting block passes through the lifting groove and is slidably connected to the mounting box. The limiting block is inserted into the corresponding vertical groove and is slidably connected to the mounting box along the length of the vertical groove.

[0056] Reference Figure 1 and Figure 2 The housing 1 is equipped with a lifting motor 43, which is located inside the mounting box. A sprocket 1 is coaxially fixed to the lifting motor 43. The operator manipulates the lifting motor 43 to drive the sprocket 1 to rotate. A sprocket 2 is rotatably connected to the upper end of the mounting box. Sprocket 1 and sprocket 2 are located on the same vertical line. A chain meshes between sprocket 1 and sprocket 2. Under the tension of sprocket 2, the rotation of sprocket 1 drives the chain to rotate. Two push blocks are fixed circumferentially on the side of the chain away from sprocket 1. The rotation of the chain drives the push blocks to move circumferentially along the chain.

[0057] Reference Figure 1 and Figure 2 On the side of the chain near the lifting plate 41, the pushing block moves vertically upwards. When the upper surface of the pushing block abuts against the lower surface of the lifting block, it causes the lifting block to move vertically upwards. The movement of the lifting block causes the lifting plate 41 to move synchronously. The lifting plate 41 is fixedly connected to two top blocks 411, which move with the lifting plate 41. The top blocks 411 correspond to the sub-plate 42. The lower end of the sub-plate 42 has a groove 421 that fits the top blocks 411. Both top blocks 411 are inserted into the corresponding grooves 421 and fit against the inner wall of the grooves 421. Through the interaction of the top blocks 411 and the grooves 421, the lifting of the top blocks 411 causes the sub-plate 42 to move, thereby causing the tamping plate 4 to move upwards as a whole.

[0058] Reference Figure 1 and Figure 2 When the push block moves to a position close to the second sprocket, it moves away from the lifting plate 41 along the circumference of the second sprocket. At this time, the push block separates from the lifting block, causing the lifting plate 41 and the auxiliary plate 42 to fall under the action of gravity, thus completing the compaction of the soil in the pit. When the pit is narrow and the auxiliary plate 42 comes into contact with the relatively hard ground around the pit, the lifting plate 41 continues to move downward under the action of gravity. At this time, the top block 411 disengages from the corresponding groove 421, and the auxiliary plate 42 and the lifting plate 41 move separately. This makes it more convenient to compact pits of different sizes. Using the crushing component 2 to crush larger diameter soil clods in the backfilled soil reduces the construction process of manually crushing large diameter soil clods and helps to improve the work efficiency during earthwork backfilling.

[0059] The implementation principle of the earthwork backfilling, spreading, and compaction device for river channel management according to this application embodiment is as follows: Soil containing clods is added into the hopper 12, allowing the soil to enter between the extrusion plate 22 and the baffle plate 21. The motor 241 drives the swing arm 243 to swing, causing the swing arm 243 to push the extrusion plate 22 towards the baffle plate 21 via the push rod 244, where it works in conjunction with the baffle plate 21 to crush the clods. The motor 241 drives the swing arm 243 to continue moving away from the installation chamber 131, thereby moving the extrusion plate 22 away from the baffle plate 21. Through the interaction of the connecting hook 25 and the straight plate 211, the baffle plate 21 pushes the soil on the support plate 14 towards the opening of the relief chamber 132, causing the soil to fall onto the upper end of the annular screen. The vibration motor 30 drives the vibrating plate 31 to vibrate, causing the soil to pass sequentially through the annular screen 32 and the annular screen 33 towards the guide opening between the two receiving plates 19, and then fall along the moving plate 192 to the corresponding position in the pit. The motor 43 drives the sprocket to rotate, which in turn drives the lifting plate 41 to move via a chain and a pusher block. As the lifting plate 41 moves, it drives the two auxiliary plates 42 to move via the top block 411. When the pusher block separates from the lifting block, the lifting plate 41 and the auxiliary plates 42 fall under the action of gravity, thus completing the compaction of the backfill soil in the pit. When backfilling, the operator does not need to crush large-diameter soil clods in advance, which helps to reduce the probability of soil clogging the screen assembly 3 and improves the work efficiency of backfilling.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
