Technical Field

[0001] This utility model relates to the field of road construction equipment technology, specifically a curbstone paving device. Background Technology

[0002] Curbstones, as an indispensable part of road construction, play a crucial role in defining road boundaries, protecting road surface structures, and guiding drainage. Currently, curbstones are mainly laid manually, but the precision of manual paving is difficult to guarantee. Once the installation precision of the curbstones deviates, it may lead to poor road drainage, serious water accumulation, and thus affect the service life of the road and driving safety. At the same time, uneven curbstones will also affect the overall aesthetics of the road. Furthermore, during the manual paving process, it is impossible to accurately fill the gaps between adjacent curbstones, which can easily lead to material overflow and waste. To solve the above problems, a curbstone paving device is needed.

[0003] An existing curbstone paving device cannot accurately position and pave the curbstone during operation, which easily leads to deviation and skew, affecting its accuracy. It also cannot accurately fill the gaps between the curbstones, which easily causes waste of filler. Therefore, there is an urgent need for a new curbstone paving device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a curbstone paving device to solve the problems of existing curbstone paving devices being unable to accurately position and pave curbstones during use, which easily leads to deviation and skewing, affecting their accuracy, and being unable to accurately fill the gaps between curbstones, which easily causes waste of filler.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a curbstone paving device, comprising a paving machine body, a feeding hopper installed on the top of the paving machine body, a pressure plate installed on the side wall of the feeding hopper, a reset spring installed at the bottom of the pressure plate, and a discharge port opened at the bottom of the feeding hopper.

[0006] A handle is installed on the top of the paving machine body, a fixing plate is installed on the inner wall of the paving machine body, and rollers are installed on the inner wall of the fixing plate.

[0007] An adjusting shaft is installed on the side wall of the paving machine body, a connecting sleeve is installed on the outer wall of the adjusting shaft, a limiting plate is installed on the outer wall of the connecting sleeve, and a curb stone is installed on the outer wall of the limiting plate.

[0008] Preferably, the feed hopper is welded to the pressure plate and is movably connected to the main body of the paving machine.

[0009] Preferably, the pressure plate forms a telescopic structure with the paving machine body through a return spring, and the discharge port is flat.

[0010] Preferably, the roller is movably connected to the fixed plate, and the roller is symmetrically arranged with the central axis of the paving machine body as the center.

[0011] Preferably, the adjusting shaft is threadedly connected to the main body of the paving machine, and the adjusting shaft is symmetrically arranged with the central axis of the main body of the paving machine as the center.

[0012] Preferably, the adjusting shaft is movably connected to the connecting sleeve, and the limiting plate is tightly fitted to the curb stone.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a feeding hopper, pressure plate, return spring and discharge port, after the main body of the paving machine is adjusted to the middle position of the adjacent curb stones, the pressure plate is pressed down and the discharge port is inserted into the gap of the adjacent curb stones. Then, cement mortar and other adhesives are injected from the feeding hopper to achieve precise filling and avoid overflow during filling, which would cause waste. After filling is completed, the pressure plate is released and the pressure plate is automatically reset by the elastic force of the return spring, which does not affect the subsequent movement of the main body of the paving machine.

[0015] 2. With the handle, fixing plate and rollers set in this utility model, when the filling is completed and paving needs to continue, the handle is pulled and the main body of the paving machine can slide horizontally along the surface of the curbstone through the setting of the rollers. Paving can continue without disassembly and assembly, thus improving the paving efficiency of curbstone.

[0016] 3. This utility model, through the setting of an adjusting shaft, connecting sleeve, limiting plate, and curbstone, adjusts the position of the limiting plate by rotating the adjusting shaft according to the width of different curbstones, thereby meeting the installation requirements of curbstones of different sizes, making it more applicable. Furthermore, after the position of the limiting plate is adjusted, the subsequent curbstone is inserted into the middle of the limiting plate. At this time, the limiting plate plays a limiting role for the subsequently inserted curbstone, preventing the subsequent inserted curbstone from shifting and improving the accuracy of curbstone paving.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] Please see Figure 1-4 A curbstone paving device includes a paving machine body 1, a feeding hopper 2 installed on the top of the paving machine body 1, a pressure plate 3 installed on the side wall of the feeding hopper 2, a return spring 4 installed at the bottom of the pressure plate 3, and a discharge port 5 opened at the bottom of the feeding hopper 2. The feeding hopper 2 is welded to the pressure plate 3 and is movably connected to the paving machine body 1. The pressure plate 3 forms a telescopic structure with the paving machine body 1 through the return spring 4. The discharge port 5 is flat. With the feeding hopper 2, pressure plate 3, return spring 4 and discharge port 5, when the paving machine body 1 is adjusted to the middle position of adjacent curbstones 12, the pressure plate 3 is pressed down, and the discharge port 5 is inserted into the gap of the adjacent curbstones 12. Then, cement mortar and other adhesives are injected from the feeding hopper 2 to achieve precise filling and avoid overflow during filling, which would cause waste. After filling is completed, the pressure plate 3 is released, and the pressure plate 3 is automatically reset by the elastic force of the return spring 4, without affecting the subsequent movement of the paving machine body 1.

[0025] Please see Figure 1-4 A curbstone paving device is provided, wherein a handle 6 is installed on the top of the paving machine body 1, a fixing plate 7 is installed on the inner wall of the paving machine body 1, and rollers 8 are installed on the inner wall of the fixing plate 7. The rollers 8 are movably connected to the fixing plate 7, and the rollers 8 are symmetrically arranged with the central axis of the paving machine body 1 as the center. Through the handle 6, the fixing plate 7 and the rollers 8, when the filling is completed and paving needs to continue, the handle 6 is pulled. At this time, the paving machine body 1 can slide horizontally along the surface of the curbstone 12 through the setting of the rollers 8, and can continue paving without disassembly, thereby improving the paving efficiency of the curbstone 12.

[0026] Please see Figure 1-4A curbstone paving device includes an adjusting shaft 9 mounted on the side wall of a paving machine body 1, a connecting sleeve 10 mounted on the outer wall of the adjusting shaft 9, a limiting plate 11 mounted on the outer wall of the connecting sleeve 10, and a curbstone 12 mounted on the outer wall of the limiting plate 11. The adjusting shaft 9 is threadedly connected to the paving machine body 1, and the adjusting shaft 9 is symmetrically arranged around the central axis of the paving machine body 1. The adjusting shaft 9 is movably connected to the connecting sleeve 10, and the limiting plate 11 is tightly fitted to the curbstone 12. The device utilizes the adjusting shaft 9 and the connecting sleeve... 10. Limiting plate 11 and curbstone 12: According to the width of different curbstones 12, the position of the limiting plate 11 is adjusted by rotating the adjusting shaft 9, so as to meet the installation requirements of different sizes of curbstones 12, making it more applicable. After the position of the limiting plate 11 is adjusted, the subsequent curbstone 12 is inserted into the middle of the limiting plate 11. At this time, the limiting plate 11 plays a limiting role for the subsequently inserted curbstone 12, preventing the subsequent inserted curbstone 12 from shifting and improving the paving accuracy of the curbstone 12.

[0027] Working principle: In use, first move the device to the desired position, then adjust the paving machine body 1 to the middle position of the adjacent curbstones 12. Press down the pressure plate 3, insert the discharge port 5 into the gap between the adjacent curbstones 12, and then inject cement mortar or other adhesives from the feed hopper 2 to achieve precise filling and avoid overflow during filling, thus preventing waste. After filling is complete, release the pressure plate 3. The pressure plate 3 will automatically return to its original position due to the elasticity of the return spring 4, without affecting the subsequent movement of the paving machine body 1. Then, when paving needs to continue after filling, pull the handle 6. At this time, the paving machine body 1 can slide horizontally along the surface of the curbstone 12 through the setting of the rollers 8, without needing to... Disassembly and reassembly allow for continued paving, improving the efficiency of curbstone 12 installation. Finally, based on the width of different curbstones 12, the position of the limiting plate 11 is adjusted by rotating the adjusting shaft 9, thereby meeting the installation requirements of curbstones 12 of different sizes, making it more versatile. After the position of the limiting plate 11 is adjusted, the subsequent curbstone 12 is inserted into the middle of the limiting plate 11. At this time, the limiting plate 11 acts as a limit for the subsequently inserted curbstone 12, preventing the subsequent inserted curbstone 12 from shifting and improving the accuracy of curbstone 12 installation. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
