Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway construction, in particular to a filling and leveling device for highway construction. Background Art
[0002] With the rapid development of road traffic, pavement maintenance and repair are becoming increasingly important. Filling and leveling equipment is an indispensable tool in highway construction and maintenance. They restore the smoothness and performance of the road surface by injecting specialized filling materials into cracks or potholes. These machines are typically equipped with a filling pipe, which precisely delivers the filling material to the area in need of repair.
[0003] However, existing filling and leveling equipment faces a key challenge: the diameter of the filling pipe is fixed and cannot be adaptively adjusted according to the size of the crack or pothole. This design limitation has led to a series of problems in practical application of the equipment.
[0004] First, fixed-diameter filling tubes are inadequate for cracks of varying sizes and shapes. For narrow cracks, an oversized filling tube may not accurately inject the material into the crack, resulting in wasted material and poor filling results. For wider cracks, an undersized filling tube may not provide sufficient flow to meet this demand. Furthermore, if the diameter of the filling tube is too small, the filling material may not have enough space to compress, leaving gaps or unrepaired areas in the crack. Utility Model Content
[0005] The purpose of the utility model is to provide a filling and leveling device for highway construction to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filling and leveling equipment for highway construction, comprising a material conveying pipe, a material guide box, a discharge port, a filling pipe, two connecting seats, two connecting plates and two connecting components, the top of the material guide box is connected to one end of the material conveying pipe, the discharge port is arranged at the bottom of the material guide box, the inner wall of the filling pipe is movably sleeved on the outer wall of the discharge pipe, the two connecting seats are respectively arranged on the left and right sides outside the filling pipe, and a card slot is opened in the two connecting seats, the two connecting plates are respectively arranged on the left and right sides of the material guide box, two connecting components are arranged on the two connecting plates, and the two connecting components are symmetrically arranged on the left and right.
[0007] Preferably, the connecting assembly includes a bracket, a threaded barrel, two slide grooves, a movable plate, a bearing seat, a screw and a block, the bracket is arranged on the outside of the connecting plate, the threaded barrel is arranged on the left side outside the bracket, the two slide grooves are respectively arranged at the top and bottom of the bracket, a movable plate is slidably connected between the two slide grooves, a bearing seat is provided on the left side of the movable plate, the screw and the threaded barrel are threadedly connected, and one end of the screw is interference fit with the inner ring of the bearing seat, the block is arranged on the right side of the movable plate, and the block movably passes through the connecting plate, and the block matches the slot.
[0008] Preferably, two positioning blocks are provided on the outer bottom of the material guide box, and positioning grooves are provided on the tops of the two connecting seats, and the positioning grooves match the positioning blocks.
[0009] Preferably, the inner wall of the filling tube is provided with a rubber ring.
[0010] Compared to existing technologies, the present invention offers the following advantages: The connection assembly allows workers to quickly change the filling tube according to the actual size of the crack, ensuring optimal repair results every time. For narrow cracks, workers can select a smaller diameter filling tube. Because the diameter of the filling tube matches the crack width, material can be injected more precisely into the crack, avoiding material waste and poor filling results. This flexibility ensures precise and efficient repairs regardless of crack size. For wider cracks, workers can quickly switch to a larger diameter filling tube. The larger diameter tube accommodates more filling material, fully filling the crack and leaving no unrepaired areas. This rapid adjustment not only improves repair efficiency but also helps maintain the overall smoothness of the road surface and ensure driving safety. More importantly, the design of the connection assembly makes this process simple and quick. Workers can easily replace the filling tube without complex tools or tedious steps. This convenience not only reduces construction costs but also minimizes construction delays caused by changing the filling tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] See also Figure 1-4 The utility model provides a filling and leveling equipment for highway construction, including a material conveying pipe 1, a material guide box 2, a discharge port 3, a filling pipe 4, two connecting seats 5, two connecting plates 6 and two connecting components 7. The top of the material guide box 2 is connected to one end of the material conveying pipe 1, and the discharge port 3 is arranged at the bottom of the material guide box 2. The material conveying pipe 1, the material guide box 2 and the discharge port 3 are connected. The inner wall of the filling pipe 4 is movably sleeved on the outer wall of the discharge pipe, and the discharge port 3 can discharge the material in the material guide box 2 into the filling pipe 4. The two connecting seats 5 are respectively arranged on the left and right sides of the filling pipe 4, and the two connecting seats 5 are provided with a card slot 10. The two connecting plates 6 are respectively arranged on the left and right sides of the material guide box 2. Two connecting components 7 are provided on the two connecting plates 6, and the two connecting components 7 are symmetrically arranged on the left and right. The connecting component 7 is used to fix the connecting seat 5, so as to fix the filling pipe 4 on the discharge port 3.
[0018] Specifically, the connecting assembly 7 includes a bracket 71, a threaded barrel 72, two slide grooves 73, a movable plate 74, a bearing seat 75, a screw 77 and a block 76. The bracket 71 is arranged on the outside of the connecting plate 6, the threaded barrel 72 is arranged on the left side outside the bracket 71, and the two slide grooves 73 are respectively arranged at the top and bottom of the bracket 71. The movable plate 74 is slidably connected between the two slide grooves 73, and a bearing seat 75 is provided on the left side of the movable plate 74. The screw 77 is threadedly connected to the threaded barrel 72, and one end of the screw 77 is interference fit with the inner ring of the bearing seat 75. The block 76 is arranged on the right side of the movable plate 74, and the block 76 moves through the connecting plate 6, and the block 76 matches the slot 10.
[0019] Specifically, two positioning blocks 8 are provided on the outer bottom of the material guide box 2, and positioning grooves 9 are provided on the tops of the two connecting seats 5, and the positioning grooves 9 match the positioning blocks 8. The positioning blocks 8 and the positioning grooves 9 facilitate the positioning of the filling tube 4 and reduce installation time.
[0020] Specifically, a rubber ring 11 is provided on the inner wall of the filling tube 4 , and the provision of the rubber ring 11 prevents leakage of materials.
[0021] Working principle: When it is necessary to replace the filling pipe 4 in the road filling and leveling equipment, first, the staff will prepare the new filling pipe 4 and align the positioning grooves 9 on the connecting seats 5 on both sides of it with the positioning blocks 8 at the bottom of the guide box 2. This step is to ensure that the filling pipe 4 can be accurately inserted into the correct position of the guide box 2 to achieve rapid positioning.
[0022] Once the positioning groove 9 is aligned with the positioning block 8 and inserted, the filling tube 4 is initially fixed on the material guide box 2. At this time, the inner wall of the filling tube 4 will fit tightly with the outer wall of the discharge port 3, ensuring that the material can flow smoothly from the material guide box 2 through the discharge port 3 into the filling tube 4.
[0023] Next, the worker begins operating the connecting assembly 7 to further secure the filling tube 4. The screw 77 in the connecting assembly 7 is a key component. As the worker rotates the screw 77 inward, the movable plate 74 is constrained by the bearing seat 75 and the slideway 73, which restricts it to a linear motion along the slideway 73. This design ensures a precise trajectory for the movable plate 74, preventing the filling tube 4 from shifting or rotating during installation.
[0024] As screw 77 rotates, movable plate 74 drives clamping block 76 toward clamping slot 10. When clamping block 76 fully enters clamping slot 10, connecting base 5 and filling tube 4 are firmly fixed to material guide box 2. At this point, the connection between filling tube 4 and material guide box 2 is stable, ensuring that material transfer will not leak or be interrupted.
[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
