Description

Technical Field

[0001] This utility model is a tool for laying out water conservancy pipes, belonging to the field of water conservancy construction. Background Technology

[0002] In the layout stage of water conservancy pipeline construction, marking the direction of trench excavation by sprinkling lime on the ground is a core step. The tool consisting of a container filled with lime powder, wheels with anti-slip texture, and an internal auger is one of the commonly used tools for sprinkling lime powder. During operation, the device is pushed, and the wheels roll along the ground, which drives the auger to rotate synchronously, gradually exporting the lime powder in the container and evenly sprinkling it on the ground to form a clear directional guide line. This provides an accurate reference for subsequent trench excavation and is suitable for the long-distance, straight layout requirements of water conservancy pipeline construction.

[0003] The complex ground conditions at water conservancy construction sites can easily lead to malfunctions in this line-laying process. The ground at construction sites is often uneven due to previous earthwork and rainwater soaking, with potholes, residual sand, weeds, construction waste, and other debris. Even with anti-slip treads on the wheel surface, various obstacles can still occur: the wheels may get stuck in potholes and unable to roll smoothly, or become jammed by sand, gravel, or weeds, causing them to spin and become stuck. When working on muddy ground, slippery mud can adhere to the anti-slip treads, weakening their effectiveness and causing the wheels to spin and slip. Obstructed wheel rolling or spinning directly prevents the auger from rotating stably. The auger may either stop rotating due to insufficient power, causing a break in the lime powder supply and resulting in gaps in the line laying and blank sections on the ground without lime lines; or the rotation speed may fluctuate, causing uneven lime powder distribution, with some areas having excessively thick lime accumulation and others having sparse and blurred lime. Uneven spreading of lime can cause the trench excavation direction to lose precise guidance, potentially leading to pipe displacement, affecting the laying accuracy of water pipelines and subsequent water conveyance function. It also requires manual respreading of lime, increasing construction costs and time consumption. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water conservancy buried pipe laying tool to solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water conservancy pipe laying tool, comprising: The container cylinder has a tube installed at its lower end, a helical rod rotatably installed inside the tube, and a dust-spreading box installed at one end of the tube, with the lower end of the dust-spreading box being open. The wheel is installed at the end of the auger rod located outside the tube. A ring is installed on the side of the wheel away from the tube. Multiple L-shaped plates are installed in a ring at equal intervals on the inner wall of the ring. Multiple through holes are opened in a ring at equal intervals on the annular side of the ring. A circular hole is opened on one side of the L-shaped plate, which is aligned with the through hole. A pointed rod is inserted into the channel formed by the through hole and the corresponding circular hole. The pointed rod is connected to the L-shaped plate by screws.

[0006] Furthermore, a connecting plate is provided on the side of the wheel away from the tube, and the connecting plate is connected to the wheel by bolts. A connecting plate is installed on the end of the L-shaped plate away from the ring, and the end of the connecting plate away from the L-shaped plate is connected and fixed to the connecting plate.

[0007] Furthermore, the connecting plate and the L-shaped plate are integrally formed, and the connecting plate and the L-shaped plate together form a "Z" shaped structure.

[0008] Furthermore, a threaded hole is provided on one side of the L-shaped plate, and the screw is threaded into the threaded hole.

[0009] Furthermore, the outer surface of the pointed rod is provided with a first positioning hole and a second positioning hole that cooperate with the screw, and the first positioning hole and the second positioning hole are arranged along the radial direction of the pointed rod.

[0010] Furthermore, a handle is provided on one side of the container cylinder, one end of the handle is connected to the tube cylinder, and the end of the handle away from the tube cylinder is inclined in a direction away from the container cylinder.

[0011] Furthermore, a U-shaped frame is installed at one end of the handle near the tube, and connecting sleeves are installed at both ends of the U-shaped frame. The connecting sleeves are fitted onto the tube and connected and fixed to the tube.

[0012] Furthermore, a rubber sleeve is fitted onto the end of the handle away from the tube, and the rubber sleeve is connected to the handle by adhesive.

[0013] The beneficial effects of this utility model are: Multiple sets of pointed rods are installed on the ring on the side of the wheel away from the pipe through L-shaped plates and perforations. When working on muddy or slippery ground, the pointed rods can insert into the surface soil or penetrate the attached soil layer to form a stable gripping point, preventing the wheel from spinning freely due to the anti-slip treads being blocked by mud. When facing potholes or gravel areas, the pointed rods can embed into ground gaps or push away small gravel, reducing wheel jamming and ensuring that the wheel rolls smoothly along the laying direction, providing a continuous and stable driving force for the auger, avoiding the interruption of auger supply due to wheel stoppage, and solving the problem of lime spreading interruption.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a water conservancy pipeline laying tool, including a container cylinder 1, a pipe cylinder 11 installed at the lower end of the container cylinder 1, a spiral rod 13 rotatably installed inside the pipe cylinder 11, and a lime powder spreading box 12 installed at one end of the pipe cylinder 11. The lower end of the lime powder spreading box 12 is open. A wheel 2 is installed at the end of the spiral rod 13 outside the pipe cylinder 11. After the wheel 2 rolls stably through the pointed rod 31, the spiral rod 13 can maintain a uniform rotation speed, continuously and evenly conveying the lime powder in the container cylinder 1 to the lime powder spreading box 12, and then smoothly spreading it to the ground from the open end of the lime powder spreading box 12. This avoids the problem of local accumulation and local sparseness caused by the sudden speed of the spiral rod 13 in traditional tools, forming a lime laying line with clear lines and consistent width, providing accurate directional guidance for trench excavation, preventing subsequent pipe laying position deviation, and ensuring the accuracy of water conservancy pipeline laying and water conveyance function.

[0017] See Figures 1-4The ring 3 is located on the side of the wheel 2 away from the tube 11. Multiple L-shaped plates 32 are installed in a ring at equal intervals on the inner wall of the ring 3. A connecting plate 34 is provided on the side of the wheel 2 away from the tube 11. The connecting plate 34 is connected to the wheel 2 by bolts. A connecting plate 33 is installed on the end of the L-shaped plate 32 away from the ring 3. The end of the connecting plate 33 away from the L-shaped plate 32 is connected and fixed to the connecting plate 34. The connecting plate 33 and the L-shaped plate 32 are integrally formed. The connecting plate 33 and the L-shaped plate 32 together form a "Z" shaped structure to connect the ring 3 and the connecting plate 34. After the connecting plate 34 is connected to the wheel 2, the position of the ring 3 and the wheel 2 is also restricted to ensure that the ring 3 rotates synchronously with the wheel 2 and there will be no relative displacement that affects the gripping effect of the pointed rod 31.

[0018] See Figures 1-4 The ring 3 has multiple equidistant perforations 37 on its annular side. One side of the L-shaped plate 32 has a circular hole 36 aligned with the perforations 37. A pointed rod 31 is inserted into the channel formed by the perforations 37 and the corresponding circular hole 36. The pointed rod 31 is connected to the L-shaped plate 32 by screws 35. The pointed rod 31 is fixed to the L-shaped plate 32 by screws 35. Damaged pointed rods 31 can be removed by unscrewing the screws 35, eliminating the need to replace the entire wheel 2 or ring 3, thus reducing maintenance costs. When the pointed rod 31 is severely worn or deformed, it can be replaced individually, ensuring the tool always maintains good gripping performance and preventing the entire tool from being scrapped due to damage to a local component. Multiple sets of pointed rods 31 are installed on the ring 3 on the side of the wheel 2 away from the pipe 11 through the L-shaped plate 32 and the perforation 37. When working on muddy or slippery ground, the pointed rods 31 can be inserted into the surface soil or penetrate the attached soil layer to form a stable gripping point, preventing the wheel 2 from spinning freely due to the anti-slip pattern being blocked by mud. When facing potholes or gravel areas, the pointed rods 31 can be embedded in the ground gaps or push away small gravel, reducing wheel 2 jamming and ensuring that the wheel 2 rolls smoothly along the laying direction, providing a continuous and stable driving force for the auger rod 13, avoiding the interruption of the auger rod 13 supply due to the wheel 2 stopping, and solving the problem of lime spreading interruption.

[0019] One side of the L-shaped plate 32 has a threaded hole, and the screw 35 is threaded into the threaded hole. The outer surface of the pointed rod 31 has a first positioning hole and a second positioning hole that mate with the screw 35. The first positioning hole and the second positioning hole are arranged along the radial direction of the pointed rod 31. When one end of the screw 35 extends into the first positioning hole, the pointed head of the pointed rod 31 extends to the outside of the wheel 2, which is suitable for complex ground such as mud and potholes. When one end of the screw 35 extends into the second positioning hole, the pointed head of the pointed rod 31 does not extend to the outside of the wheel 2. The pointed rod 31 can be hidden when working on flat ground to avoid unnecessary wear caused by friction between the pointed rod 31 and the ground. This allows for flexible switching between the working state and the storage state of the pointed rod 31, adapting to different ground conditions.

[0020] See Figure 1 and Figure 2 A handle 4 is provided on one side of the container cylinder 1. One end of the handle 4 is connected to the tube cylinder 11. The end of the handle 4 away from the tube cylinder 11 is inclined in a direction away from the container cylinder 1. A U-shaped frame 41 is installed at the end of the handle 4 near the tube cylinder 11. Connecting sleeves 42 are installed at both ends of the U-shaped frame 41. The connecting sleeves 42 are fitted onto the tube cylinder 11 and connected and fixed to the tube cylinder 11. A rubber sleeve is fitted at the end of the handle 4 away from the tube cylinder 11. The rubber sleeve is connected to the handle 4 by glue. The U-shaped frame 41 and the connecting sleeves 42 serve to connect the handle 4 and the tube cylinder 11, enhancing the stability of the connection between the handle 4 and the tube cylinder 11. The handle 4 on the side of the container cylinder 1 is inclined in a direction away from the container cylinder 1, which conforms to the ergonomic design. When the operator pushes the tool, there is no need to bend over to exert force, reducing arm and waist fatigue. The rubber sleeve at the end of the handle 4 increases the friction of the hand, preventing the hand from slipping during pushing, and improving the safety and comfort of operation.
