Description

Technical Field

[0001] This invention belongs to the field of caisson construction technology, specifically relating to a caisson construction material layering and laying device. Background Technology

[0002] Caisson construction involves using a pre-cast reinforced concrete shaft-shaped structure on the ground as a support for the foundation pit walls. Protected by these walls, soil is excavated inside the pit using machinery and manual labor, and the structure sinks into the ground under its own weight. Therefore, caisson construction is essentially the process of sinking a pre-cast structure on the ground to a certain depth underground to become an underground structure.

[0003] A related technology (publication number CN213539029U) discloses a prefabricated caisson that is easy to construct, including an arc-shaped plate. Multiple arc-shaped plates are spliced ​​together to form a sleeve, and multiple sleeves are connected end to end to form a caisson body. A horizontal connector is provided between two adjacent arc-shaped plates within the same sleeve, and a vertical connector is provided between two adjacent vertical sleeves. The two adjacent vertical connectors are connected end to end. This application uses prefabricated arc-shaped plates in a factory and assembles them on-site to form the caisson body, reducing wet work on the construction site and improving construction efficiency.

[0004] When laying materials for existing caisson construction, the materials must first be sorted by particle size before being placed into the caisson. Then, manual labor using paving tools is required to spread the materials of different particle sizes sequentially. Firstly, the process of placing all materials into the caisson at once and then manually distributing and spreading them using tools is time-consuming, resulting in a long overall construction period for the caisson. Secondly, the need for manual paving of different particle sizes means that construction workers must repeatedly perform the work of spreading multiple layers of material. This repetitive and time-consuming process leads to low overall efficiency in caisson material laying. Summary of the Invention

[0005] To address the problems of existing caisson construction materials, which require material separation by particle size before being placed into the caisson and then manually spread using paving tools, resulting in a long construction period, repetitive steps, and significant time consumption, this invention provides a caisson construction material layering device that integrates material particle size separation and paving functions. This eliminates the cumbersome steps of separating materials by particle size and manual paving, shortening the overall construction period. It also enables targeted paving of materials of different particle sizes, eliminating the need for repeated manual paving steps and further saving time. Furthermore, the material is dispersed through corresponding through-holes, falling evenly to the bottom of the caisson, avoiding local accumulation or gaps, and promoting more uniform paving. This method also avoids the lower strength of traditional piled-up material paving. The specific technical solution is as follows:

[0006] A material layering and laying device for caisson construction includes a support frame, which is a hollow annular body. A feeding bin is rotatably disposed within the support frame, and a diversion component is disposed within the feeding bin. The diversion component enables material to be processed and output according to particle size. Multiple support arms are vertically and fixedly installed on the sidewalls of the support frame, with adjacent support arms spaced at equal angles. A fixed base is fixedly installed at the bottom end of each support arm, and a base plate is fixedly installed on the sidewall of the fixed base. Several sets of through holes are arranged circumferentially on the base plate, with each set of through holes equidistant from the center of the base plate to its edge. The diversion component rotates intermittently circumferentially about the center of the feeding bin. When the output end of the diversion component corresponds to one of the sets of through holes, material is dispersedly dispensed. A paving component that rotates synchronously with the feeding bin is disposed below the base plate.

[0007] In the above technical solution, multiple sets of fixing blocks are fixedly installed on the side wall of the feeding bin. The multiple sets of fixing blocks are tightly fitted on the side wall of the feeding bin in the circumferential direction. The multiple sets of tightly fitted fixing blocks form an annular body on the side wall of the feeding bin. Each fixing block is provided with a sliding groove. The sliding groove is U-shaped. A limiting piece is fixedly installed on the side wall of the feeding bin. The side wall of the limiting piece is provided with a number of recesses at equal intervals in the circumferential direction.

[0008] In the above technical solution, the center point of the recess and the center point of the two adjacent grooves are located on the same vertical line.

[0009] In the above technical solution, the side wall of the feeding bin is provided with a drive unit that drives the feeding bin to rotate intermittently;

[0010] The drive unit includes a frame and a motor fixedly mounted on the top of the frame. The output end of the motor is connected to one end of a first rotating shaft, and the other end of the first rotating shaft is rotatably connected to the frame. A rotating rod and a limiting plate are fixedly mounted on the first rotating shaft, and the limiting plate is located below the rotating rod. A lever is mounted on the side of the rotating rod away from the first rotating shaft. The lever is slidably embedded in the inner cavity of the groove, and the side wall of the limiting plate is rotatably fitted with the recess.

[0011] In the above technical solution, the frame is connected to one of the support arms via a support component;

[0012] The support assembly includes a sleeve fixedly fitted onto one of the support arms, and a plurality of connecting rods installed on the side wall of the sleeve, the connecting rods being fixedly connected to the frame.

[0013] In the above technical solution, the diversion component includes a screen and a guide plate installed in the inner cavity of the feeding hopper. The screen is a plate with mesh holes and is inclined upward from left to right. The guide plate is located below the screen and is inclined downward from left to right. The left and right side walls of the feeding hopper are respectively connected to a first main pipe and a second main pipe. The first main pipe corresponds to the left end of the screen, and the second main pipe corresponds to the right end of the guide plate.

[0014] In the above technical solution, output components are respectively provided at the bottom ends of the first main pipe and the second main pipe;

[0015] The output component includes a material cylinder connected to the first main pipe or the second main pipe. Multiple material feeding sub-pipes are equidistantly connected to the bottom end of the material cylinder. When the material feeding sub-pipes are rotated to correspond to the position of one of the through holes, the material is dispersed and fed out.

[0016] In the above technical solution, each of the material cylinder cavities is provided with a guide assembly;

[0017] The guiding assembly includes a second rotating shaft rotatably connected inside the material cylinder, with the center of the second rotating shaft collinear with the center of the material cylinder. A roller is fixedly mounted on the second rotating shaft. The roller is shaped like a frustum, narrow at both ends and wide in the middle, and is symmetrically arranged with respect to the vertical center line of the material cylinder. The diameter of the middle part of the roller is twice the diameter of the end part of the roller. The end of the second rotating shaft near the center of the base plate extends out of the side wall of the material cylinder, and a gear is fixedly mounted on the end of the second rotating shaft. A hole is opened through the center of the base plate, and a hollow cylinder is fixedly mounted in the middle of the base plate, located outside the hole in the center of the base plate. A plurality of teeth are evenly spaced along the circumference on the upper surface of the hollow cylinder, and the gear meshes with the teeth.

[0018] In the above technical solution, the paving assembly includes a connecting column fixedly installed at the bottom of the feeding hopper, and the center of the connecting column coincides with the center of the bottom end face of the feeding hopper. The connecting column passes through a hole opened at the center of the bottom plate. A first paving plate and a second paving plate are respectively installed at the bottom of the connecting column. The first paving plate and the second paving plate are spaced 180 degrees apart. The first paving plate is located in the counterclockwise direction of the first main pipeline, and the second paving plate is located in the counterclockwise direction of the second main pipeline.

[0019] In the above technical solution, a plurality of guide flanges are equidistantly arranged on the roller.

[0020] The material layering and laying device for caisson construction of the present invention has the following advantages compared with the prior art:

[0021] I. Existing methods for laying materials in caisson construction require prior particle size separation before individual material placement into the caisson. This necessitates manual spreading of materials of different particle sizes using paving tools, resulting in a lengthy construction period, repetitive steps, and significant time consumption. This invention addresses this issue by incorporating a particle size separation function within the material feeding hopper. This function automatically separates and grades the caisson materials during material placement. Through the material cylinder, feeding pipes, bottom plate, and through-holes, the materials are dispersed and spread using corresponding first and second paving plates. This invention integrates particle size separation and paving functions, eliminating the tedious steps of separate material placement and manual spreading after particle size separation. This reduces the overall construction time of the caisson and enables targeted paving of materials of different particle sizes, eliminating the need for repeated manual spreading steps and further saving time.

[0022] Second, by setting up a feeding bin, a screen, and a guide plate, this invention can separate materials into two different particle sizes and promote the two different particle sizes of materials to enter the corresponding first main pipe and second main pipe for subsequent transportation. That is, the material of this invention can be automatically processed by particle size and classified and guided out through the feeding bin, which prepares for the subsequent layered spreading of materials.

[0023] Third, in response to the problem that the existing method of uniformly placing materials into the caisson results in the materials being concentrated inside the caisson and the subsequent paving work being large, in this invention, when several material distribution pipes correspond one-to-one with the through holes, the materials can be placed in a dispersed manner through the corresponding through holes, and the materials in the caisson fall dispersedly to the bottom of the caisson, avoiding local accumulation or gaps, which is more conducive to the uniform paving of the materials in the subsequent process, and the paving intensity is lower than that of the traditional method of piling up materials.

[0024] Fourth, in this invention, after the material falls through the corresponding through holes, it is distributed in a dispersed manner, and the two particle sizes are spread under the successive rotation of the first paving plate and the second paving plate, without the need for manual paving with the help of tools.

[0025] Fifth, in this invention, the intermittently rotating fixed block and chute can drive the feeding bin, connecting column, first paving plate and second paving plate to rotate synchronously and intermittently. That is, this invention can achieve the intermittent circumferential dispersion of materials and the paving of different layers of materials by using the same power. This reduces the time and manpower required to perform two operations separately in traditional construction, significantly shortens the construction cycle, and reduces energy consumption and the operating costs of unnecessary multiple power sources during construction.

[0026] VI. In this invention, the motor, first rotating shaft, limiting disc, rotating rod, and lever can cause the fixed block, sliding groove, limiting plate, and recess to rotate intermittently and lock after rotation. This, in turn, causes the feeding bin and several discharging pipes to rotate intermittently and lock after rotation. It can also ensure that the discharging pipes and through holes correspond after each intermittent rotation, achieving precise dispersion of materials in the caisson. This ensures the efficient operation of the entire material feeding system without additional adjustment or calibration work. It can also effectively reduce safety hazards and maintenance costs caused by uneven settlement and other problems in the later stages. Furthermore, the intermittent rotation and locking mechanism ensures the controllability of the construction process. Construction personnel can precisely control the rhythm of material feeding according to actual needs, avoiding material waste or insufficient feeding caused by continuous feeding.

[0027] VII. In this invention, the number of through holes and chutes in each group is the same. By driving the chutes to rotate once by the lever, each group of material feeding pipes can rotate to correspond to the through hole. That is, after each intermittent rotation of the material feeding pipe, the locked and limited position can maintain an upper and lower correspondence with the corresponding through hole, ensuring that the material feeding pipe after each rotation can accurately distribute and feed materials.

[0028] 8. The material cylinder of the present invention is equipped with rollers, which can make the material falling from the first main pipe and the second main pipe evenly fill the inner cavity of the material cylinder, thereby ensuring that the multiple feeding sub-pipes connected to the material cylinder can achieve sufficient material feeding. Compared with the traditional method of simply setting up a material cylinder and feeding sub-pipes, which is prone to insufficient material at both ends of the material cylinder and uneven feeding of multiple feeding sub-pipes, the present invention, by setting up rollers, can make it easier for the material to fill both ends of the inner cavity of the material cylinder, so that the feeding sub-pipes corresponding to the left and right ends of the material cylinder have enough material to be fed down.

[0029] 9. The present invention, through teeth, gears, a second rotating shaft and rollers, can cause the rollers to rotate relative to the material cylinder. The rollers rotating inside the material cylinder can accelerate the flow of the material in the material cylinder, and cause the material to fill the interlayer space between the material cylinder and the rollers more quickly and evenly.

[0030] 10. This invention, through the arrangement of a feeding bin, connecting column, hollow cylinder, and teeth, enables the gears to rotate along the teeth when the feeding bin rotates, thereby causing the rollers inside the cylinder to rotate. The rotation of the rollers does not require other power; the rotation of the rollers inside the cylinder is achieved solely through the rotation of the feeding bin, thus ensuring sufficient material distribution and delivery. The equipment exhibits stronger linkage and higher coordination. This high degree of linkage and coordination enhances the intelligence of the equipment, reduces the need for additional power sources, and minimizes potential failure points and instability factors. The close linkage between various components makes the equipment more coordinated and consistent during operation, reducing downtime and maintenance time caused by power mismatch or malfunction, and ensuring the continuity and efficiency of construction.

[0031] 11. The present invention provides a guide flange on the outer wall of the roller. The guide flange can assist the roller in moving the material in the cylinder more quickly. The roller is designed as a frustum shape that is narrow at both ends and wide in the middle, which promotes the smooth flow of material in the cylinder to both ends of the cylinder. This ensures that the corresponding feed pipes at both ends of the cylinder can receive effective material feeding, and avoids the situation where material falls into the inner cavity of the first main pipe and into the inner cavity of the cylinder, resulting in more material in the middle of the cylinder and less material at both ends, which would cause uneven material feeding.

[0032] In summary, this invention integrates material particle size separation and paving functions, eliminating the tedious steps of separate material delivery and manual paving after particle size separation, thus shortening the overall construction period of the caisson. It also enables targeted paving of materials with different particle sizes, eliminating the need for repeated manual paving steps and saving even more time. Furthermore, the material is delivered in a dispersed manner through corresponding through-holes, allowing it to fall evenly to the bottom of the caisson, avoiding local accumulation or gaps, and promoting more uniform paving. Compared to traditional piled material paving, this method results in lower paving intensity. Additionally, using the same power source, it can achieve intermittent circumferential dispersion of material delivery while automatically paving different layers of material, reducing the need for manual paving. The time and manpower required for two separate operations in traditional construction are significantly reduced, thus shortening the construction cycle, reducing energy consumption and the operating costs of unnecessary multiple power sources during construction. In addition, the rotation of the feeding hopper enables the rollers to rotate within the material cylinder, achieving sufficient material distribution and feeding. The equipment has stronger linkage and higher coordination, which improves the intelligence level of the equipment. The reduction of additional power sources reduces potential failure points and instability factors. The close linkage between various components makes the equipment more coordinated during operation, reducing downtime and maintenance time caused by power mismatch or failure, and ensuring the continuity and efficiency of construction.

[0042] The following are specific implementation cases and appendices. Figures 1 to 8 The present invention will be further described, but the present invention is not limited to these embodiments.

[0043] Main references Figures 1 to 8 As shown, a material layering and laying device for caisson construction includes a support frame 1, which is a hollow annular body. A feeding bin 2 is rotatably disposed within the support frame 1, allowing for circumferential dispersion of materials at the bottom of the caisson cavity. The feeding bin 2 is equipped with a diversion component, which enables material particle size separation and output, integrating material particle size separation and spreading functions. This eliminates the cumbersome steps of separate material feeding and manual spreading after particle size separation, thus shortening the overall construction period of the caisson. Multiple support arms 12 are vertically and fixedly installed on the sidewalls of the support frame 1. In this embodiment, four support arms 12 are provided, with the same angle between adjacent support arms 12, i.e., every two adjacent support arms 12 are spaced 90 degrees apart, ensuring that each support arm 12 is equidistantly distributed at the bottom of the support frame 1, thereby ensuring that the support arms 12 can... The support frame 1 is circumferentially equidistantly supported. A fixed base 11 is fixedly installed at the bottom of the support arm 12. A base plate 9 is fixedly installed on the side wall of the fixed base 11. The support arm 12 and the fixed base 11 are used to connect the support frame 1 and the base plate 9, so that the support frame 1 and the base plate 9 form a stable fixed connection relationship. Several sets of through holes 10 are arranged in a circumferential array on the base plate 9. In this embodiment, there are twelve sets of through holes 10, and each set of through holes 10 has five holes. Each set of through holes 10 is equidistantly arranged from the center of the base plate 9 to the edge of the base plate 9. The diversion component rotates intermittently in the circumferential direction with the center of the feeding bin 2 as the axis. When the output end of the diversion component corresponds to the position of one set of through holes 10, the material is dispersed and fed. A paving component is set below the base plate 9 and rotates synchronously with the feeding bin 2. The paving component is used to spread the fed material on the bottom of the caisson cavity, so that the material is spread flat without the need for manual leveling with tools.

[0044] For details, please refer to the main references. Figure 1 , Figure 6 and Figure 7 As shown, multiple sets of fixing blocks 13 are fixedly installed on the side wall of the feeding bin 2. In this embodiment, twelve sets of fixing blocks 13 are provided. The multiple sets of fixing blocks 13 are tightly fitted on the side wall of the feeding bin 2 along the circumference. The multiple sets of tightly fitted fixing blocks 13 form a ring on the side wall of the feeding bin 2. Each fixing block 13 is provided with a sliding groove 14, that is, twelve sliding grooves 14 are provided. The sliding grooves 14 are U-shaped. A limiting piece 15 is fixedly installed on the side wall of the feeding bin 2. The side wall of the limiting piece 15 is provided with a number of recesses 16 at equal intervals along the circumference. In this embodiment, twelve recesses 16 are provided. That is, in this application, the number of sets of through holes 10, the number of sliding grooves 14, and the number of recesses 16 are all set to the same number to ensure that every time the sliding groove 14 rotates a unit distance, the recesses 16 and the diversion component rotate synchronously by a unit distance, and the diversion component is still above each set of through holes 10 at different positions after each rotation.

[0045] Main references Figure 1 , Figure 6 and Figure 7 As shown, a drive unit is provided on the side wall of the feeding bin 2 to drive the feeding bin 2 to rotate intermittently; the drive unit includes a frame 19 and a motor 20 fixedly installed on the top of the frame 19. The output end of the motor 20 is connected to one end of a first rotating shaft 21, and the other end of the first rotating shaft 21 is rotatably connected to the frame 19 through a bearing. A rotating rod 23 and a limiting plate 22 are fixedly installed on the first rotating shaft 21, and the limiting plate 22 is located below the rotating rod 23. A lever 24 is installed on the side of the rotating rod 23 away from the first rotating shaft 21. The lever 24 is slidably embedded in the inner cavity of the slide groove 14, and the side wall of the limiting plate 22 rotates and fits against the recess 16; the motor is turned on. 20 drives the first rotating shaft 21, the limiting disk 22, the rotating rod 23, and the lever 24 to rotate synchronously. During the rotation, the lever 24 slides and embeds itself into one end of the slide groove 14. As the lever 24 continues to rotate, it moves the slide groove 14, the fixed block 13, and the feeding bin 2, rotating one unit distance circumferentially around the center of the feeding bin 2. As the lever 24 continues to rotate and disengages from the inner cavity of the slide groove 14, the side wall of the limiting disk 22 rotates accurately to fit against the recess 16, thereby limiting the limiting piece 15 and preventing it from continuing to rotate. At this time, the feeding bin 2, which is fixedly connected to the limiting piece 15, becomes stable and will not continue to rotate.

[0046] Main references Figure 1As shown, the frame 19 is connected to one of the support arms 12 via a support assembly. The support assembly includes a sleeve 17 fixedly sleeved on one of the support arms 12, and a plurality of connecting rods 18 installed on the side wall of the sleeve 17. The connecting rods 18 are fixedly connected to the frame 19. In this embodiment, three connecting rods 18 are provided. The middle connecting rod 18 is set perpendicular to the sleeve 17, and the upper and lower connecting rods 18 are symmetrically inclined relative to the middle connecting rod 18. Thus, a stable fixed connection between the sleeve 17 and the frame 19 is achieved by means of the three connecting rods 18 to ensure the stability of the components on the frame 19.

[0047] Main references Figure 6 and Figure 7 As shown, the center point of the recess 16 and the center point of the two adjacent slides 14 are located on the same vertical line. This ensures that after the feeding bin 2, the fixing block 13, the slide 14, the limiting plate 15, and the recess 16 rotate synchronously by one unit distance, the limiting plate 22 can accurately correspond to the side wall of the recess 16 and limit the recess 16. This ensures that the recess 16, the fixing block 13, and the slide 14 are stable after being limited. Moreover, the U-shaped opening of the slide 14 can accurately correspond to the rotation trajectory of the next circumferential rotation of the lever 24. That is, it ensures that the slide 14, after rotation, can accurately correspond to the next circumferential rotation of the lever 24.

[0048] Main references Figure 1 and Figure 5As shown, the diversion assembly includes a screen 3 and a guide plate 4 installed inside the feeding hopper 2. The screen 3 is a plate with mesh openings and is inclined upwards from left to right. The guide plate 4 is located below the screen 3 and is inclined downwards from left to right. The left and right side walls of the feeding hopper 2 are respectively connected to a first main pipe 5 and a second main pipe 6. The first main pipe 5 corresponds to the left end of the screen 3, and the second main pipe 6 corresponds to the right end of the guide plate 4. After the sedimentation material is fed into the feeding hopper 2, it is divided into two particle size grades by the screen 3. The larger particle size material is blocked by the screen 3 and flows to the left along the surface of the screen 3 into the inner cavity of the first main pipe 5. The smaller particle size material is separated into two particle size grades by the screen 3. The material passes downward through the screen 3 and enters the inner cavity of the second main pipe 6 under the guidance of the guide plate 4; the bottom ends of the first main pipe 5 and the second main pipe 6 are respectively provided with output components; the output components include a material cylinder 7 connected to the first main pipe 5 or the second main pipe 6, and the bottom end of the material cylinder 7 is equidistantly connected with multiple feeding sub-pipes 8. In this embodiment, the number of feeding sub-pipes 8 is set to five. When the feeding sub-pipes 8 are rotated to correspond to the position of one of the through holes 10, the material is dispersed and fed out. That is, the number of feeding sub-pipes 8 is the same as the number in each group of through holes 10, ensuring that the feeding sub-pipes 8 after rotation correspond to each through hole 10, so that the material in the inner cavity of the material cylinder 7 is evenly dispersed downward through each feeding sub-pipe 8 and through hole 10.

[0049] When the feeding bin 2 rotates, the first main pipe 5, the second main pipe 6, and the corresponding material cylinder 7 and the discharge branch pipe 8 installed on the side wall of the feeding bin 2 rotate synchronously. For every unit distance that the feeding bin 2 rotates, the discharge branch pipe 8 rotates to the position above the next set of corresponding through holes 10. When the discharge branch pipe 8 rotates along the upper surface of the bottom plate 9, the material is blocked by the upper surface of the bottom plate 9, and the material will not be discharged at this time. When the discharge branch pipe 8 rotates to the position corresponding to the through hole 10, the material can be discharged downward through the corresponding through hole 10.

[0050] Main references Figure 4 and Figure 8As shown, each material cylinder 7 has a guide assembly inside its cavity. The guide assembly includes a second rotating shaft 33 rotatably connected to the material cylinder 7 via bearings. The center of the second rotating shaft 33 is collinear with the center of the material cylinder 7, ensuring that the second rotating shaft 33 is installed in the middle of the material cylinder 7. A roller 34 is fixedly mounted on the second rotating shaft 33. The roller 34 is shaped like a frustum, narrow at both ends and wide in the middle. The roller 34 is symmetrically arranged with respect to the vertical center line of the material cylinder 7, ensuring that the interlayer space formed by the roller 34 and the material cylinder 7 is symmetrical and equidistant from the inner wall of the material cylinder 7. The diameter of the middle part of the roller 34 is twice the diameter of the end part of the roller 34, ensuring that the roller 34 forms a guide space that is wide in the middle and narrow at both ends. This facilitates the smooth flow of material in the material cylinder 7 to both ends, ensuring that the corresponding discharge pipes 8 at both ends of the material cylinder 7 can receive effective material feeding and avoid... To prevent uneven material feeding caused by material falling from the inner cavity of the first main pipe 5 into the inner cavity of the cylinder 7, resulting in more material in the middle and less at the ends of the cylinder 7, the end of the second rotating shaft 33 near the center of the bottom plate 9 extends out of the side wall of the cylinder 7. A gear 36 is fixedly installed at the end of the second rotating shaft 33. A hole is opened through the center of the bottom plate 9. A hollow cylinder 31 is fixedly installed in the middle of the bottom plate 9 and is located outside the hole in the center of the bottom plate 9. Several teeth 32 are evenly arranged circumferentially on the upper surface of the hollow cylinder 31. The gear 36 meshes with the teeth 32, that is, the gear 36 can rotate circumferentially along the outer wall of the teeth 32 while meshing with the teeth 32. In addition, several guide flanges 35 are evenly arranged on the roller 34. The guide flanges 35 can assist the roller 34 in moving the material in the cylinder 7 more quickly.

[0051] As the feeding bin 2 rotates, the two gears 36 corresponding to the bottom ends of the first main pipe 5 and the second main pipe 6 rotate synchronously with the feeding bin 2. Since the gears 36 are meshed with the teeth 32, the rotating gears 36 can rotate along the surface of the teeth 32. At the same time, the gears 36 can revolve around the center of the connecting column 25. The rotating gears 36 drive the corresponding second rotating shaft 33 to rotate, so that the rollers 34 and guide flanges 35 in the inner cavity of the material cylinder 7 can rotate synchronously. The rotating rollers 34 can accelerate the material to quickly fill the space between the material cylinder 7 and the rollers 34, and guide the material to move to both ends of the material cylinder 7, further ensuring that the subsequent material fills the space between the material cylinder 7 and the rollers 34.

[0052] Main references Figure 1 , Figure 3 and Figure 4As shown, the paving assembly includes a connecting column 25 fixedly installed at the bottom of the feeding bin 2, and the center of the connecting column 25 coincides with the center of the bottom end face of the feeding bin 2. The connecting column 25 passes through the hole opened at the center of the bottom plate 9. When the connecting column 25 rotates with the feeding bin 2, it will not affect the bottom plate 9. A first paving plate 26 and a second paving plate 27 are respectively installed at the bottom of the connecting column 25. The first paving plate 26 and the second paving plate 27 are spaced 180 degrees apart. The first paving plate 26 is set in the counterclockwise direction of the first main pipe 5, and the second paving plate 27 is set in the counterclockwise direction of the second main pipe 6.

[0053] As the feeding bin 2 rotates, the connecting column 25, the first paving plate 26, and the second paving plate 27 fixedly installed at the bottom of the feeding bin 2 rotate synchronously with the feeding bin 2. When large-diameter materials in the inner cavity of the first main pipe 5, the material cylinder 7, and the discharge branch pipe 8 are fed through the corresponding through holes 10, the first paving plate 26, which rotates clockwise, can smooth out the fed large-diameter materials. When small-diameter materials in the inner cavity of the second main pipe 6, the material cylinder 7, and the discharge branch pipe 8 are fed through the corresponding through holes 10, the second paving plate 27, which rotates clockwise, can smooth out the fed small-diameter materials. Thus, with the same power, while realizing the intermittent circumferential dispersion of materials, it can also automatically realize the paving of materials of different levels.

[0054] In addition, the main references Figure 1 and Figure 2 As shown, a ring 28 is fixedly installed on the side wall of the feeding bin 2. Multiple rollers 29 are installed at equal intervals along the circumference at the bottom end of the ring 28. In this embodiment, four sets of rollers 29 are provided, and the four sets of rollers 29 are evenly spaced at the bottom end of the ring 28. A slide rail 30 is provided on the upper surface of the support frame 1, and the rollers 29 are rolled and embedded in the inner cavity of the slide rail 30. When the feeding bin 2 rotates, the rollers 29 are caused to roll along the inner cavity of the slide rail 30, thereby supporting the rotation of the feeding bin 2 and ensuring that the feeding bin 2 remains stable when rotating relative to the support frame 1.

[0055] It is worth noting that in this application, the motor 20 is a self-locking motor that is commonly used in the market and whose output end can be locked. When it stops, its output end can be self-locked and will not rotate under external force. In addition, the motor 20 is a commonly used forward and reverse motor, and its output end can rotate in the forward or reverse direction according to the usage requirements. It is sufficient to meet the above usage requirements. The existing components mentioned above will not be described in detail here.

[0056] The following explanation uses the principle of laying materials in caissons in two different particle sizes as an example:

[0057] After the material is fed into the caisson via the feeding bin 2, it is separated into two particle size grades by the screen 3. The larger particle size material enters the inner cavity of the first main pipe 5 along the surface of the screen 3 under the screening and blocking effect of the screen 3, while the smaller particle size material passes through the screen 3 downward and enters the inner cavity of the second main pipe 6 under the guidance of the guide plate 4. The two types of materials that have entered the inner cavities of the first main pipe 5 and the second main pipe 6 continue to enter the inner cavity of the corresponding material cylinder 7. Under the action of the roller 34 in the inner cavity of the material cylinder 7, the material fills the interlayer space between the material cylinder 7 and the roller 34, so that the material can be evenly fed through multiple feeding distribution pipes 8 in the future.

[0058] The motor 20 drives the first rotating shaft 21, the limiting plate 22, the rotating rod 23, and the lever 24 to rotate synchronously. During rotation, the lever 24 slides and embeds itself into one end of the slide groove 14. As the lever 24 continues to rotate, it actuates the slide groove 14, the fixing block 13, and the feeding bin 2, causing the feeding bin 2 to rotate circumferentially one unit distance around its center. At this time, the first main pipe 5, the second main pipe 6, and the corresponding material cylinder 7 and discharge branch pipe 8 installed on the side wall of the feeding bin 2 rotate synchronously. Each unit of rotation of the feeding bin 2... Rotating one unit distance causes the feeding pipe 8 to rotate above the next corresponding through hole 10. When the feeding pipe 8 rotates along the upper surface of the base plate 9, the material is blocked by the upper surface of the base plate 9, and the material will not be fed. When the feeding pipe 8 rotates to the position corresponding to the through hole 10, the material can be fed downward through the corresponding through hole 10. As the lever 24 continues to rotate and disengages from the inner cavity of the slide 14, the side wall of the limiting plate 22 rotates accurately to the position where it fits against the recess 16, thus limiting the movement at this time. The limiting plate 15 is positioned to prevent further rotation. At this time, the feeding bin 2, which is fixedly connected to the limiting plate 15, becomes stable and stops rotating. The discharging pipe 8 aligns with the through hole 10, and the material in the discharging pipe 8 is discharged downwards through the through hole 10 in a dispersed manner. Simultaneously, the rotation of the feeding bin 2 causes the connecting column 25, the first paving plate 26, and the second paving plate 27, which are fixedly installed at the bottom of the feeding bin 2, to rotate synchronously with the feeding bin 2. When the inner cavities of the first main pipe 5, the material cylinder 7, and the discharging pipe 8... After large-diameter materials are fed through the corresponding through holes 10, the first paving plate 26, which rotates clockwise, can flatten the fed large-diameter materials. When small-diameter materials are fed through the corresponding through holes 10 in the inner cavities of the second main pipe 6, the material cylinder 7, and the feeding distribution pipe 8, the second paving plate 27, which rotates clockwise, can flatten the fed small-diameter materials. Thus, with the same power, while realizing the intermittent circumferential dispersion of materials, it can also automatically realize the paving of different levels of materials.

[0059] Simultaneously, as the feeding bin 2 rotates, the two gears 36 corresponding to the bottom ends of the first main pipe 5 and the second main pipe 6 rotate synchronously with the feeding bin 2. Since the gears 36 are meshed with the teeth 32, the rotating gears 36 can rotate along the surface of the teeth 32. At the same time, the gears 36 can revolve around the center of the connecting column 25. The rotating gears 36 drive the corresponding second rotating shaft 33 to rotate, so that the rollers 34 and guide flanges 35 in the inner cavity of the material cylinder 7 rotate synchronously. The rotating rollers 34 can accelerate the material to quickly fill the space between the material cylinder 7 and the rollers 34, and guide the material to move to both ends of the material cylinder 7, further ensuring that the subsequent material fills the space between the material cylinder 7 and the rollers 34, so as to ensure that the material in the inner cavity of the subsequent multiple feeding pipes 8 can be effectively and adequately fed.

[0060] This invention integrates material particle size separation and paving functions, eliminating the tedious steps of separate material delivery and manual paving after particle size separation, thus shortening the overall construction period of the caisson. It also enables targeted paving of materials of different particle sizes, eliminating the need for repeated manual paving steps and saving even more time. Furthermore, the material is delivered in a dispersed manner through corresponding through-holes 10, allowing it to fall evenly to the bottom of the caisson, avoiding local accumulation or gaps, and promoting more uniform paving. Compared to traditional piled material paving, this method results in lower paving strength. Additionally, using the same power source, while achieving intermittent circumferential dispersion of material delivery, it can also automatically pave different layers of material, reducing the traditional... The time and manpower required for the two operations during construction are reduced, significantly shortening the construction cycle and reducing energy consumption and the operating costs of unnecessary multiple power sources during construction. In addition, the rotation of the feeding bin 2 enables the roller 34 to rotate within the material cylinder 7, achieving sufficient material distribution and feeding. The equipment has stronger linkage and higher coordination. The high degree of linkage and coordination improves the intelligence level of the equipment. The reduction of additional power sources can reduce potential failure points and instability factors. The close linkage between various components makes the equipment more coordinated and consistent during operation, reducing downtime and maintenance time caused by power mismatch or failure, and ensuring the continuity and efficiency of construction.
