[0001] This utility model belongs to the field of road construction technology, specifically an auxiliary device for widening roadbed. Background Technology

[0002] The roadbed of an urban road is a strip structure constructed according to the road's horizontal position, design elevation, and certain technical requirements. The roadbed is the foundation that supports the road surface, bears the road surface's own weight and the traffic load transmitted through the road surface, and withstands the effects of natural factors such as temperature and humidity changes throughout the year.

[0003] Existing roadbed widening auxiliary devices, during use, may have uneven distribution of filling materials due to different road conditions, resulting in uneven roadbeds. The existing equipment cannot effectively and promptly level the roadbed surface, which can easily lead to uneven road surfaces and affect vehicle traffic. External tools are needed to flatten the road surface again, resulting in low roadbed widening efficiency.

[0004] Therefore, an auxiliary device for widening the roadbed is proposed to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides an auxiliary device for widening roadbeds, which solves the problem that existing devices are difficult to flatten materials in a timely manner when widening and adjusting the roadbed, easily leading to uneven roads and affecting vehicle traffic.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for widening roadbed, comprising a material bucket, a feeding box fixedly connected to the bottom of the material bucket, a feeding port fixedly provided at the bottom of the feeding box, the material bucket, the feeding box and the feeding port being connected, an inlet provided on the side of the material bucket, a stirring component for stirring materials provided inside the material bucket, mounting frames fixedly connected to symmetrical sides of the outer wall of the material bucket, a pusher fixedly connected to the top of the mounting frame, connecting frames fixedly connected to the four corners of the bottom of the mounting frame, casters fixedly provided at the bottom of multiple connecting frames, and a flattening mechanism provided at the bottom of the mounting frame;

[0007] The flattening mechanism includes multiple pressure rollers, each with a rotating shaft at its center. The rotating shaft passes through the pressure rollers and is rotatably connected to them. A cleaning assembly is provided on the top of each pressure roller, and drive assemblies for rotating the pressure rollers are provided on both symmetrical sides of the bottom of the mounting frame.

[0008] Preferably, the plurality of pressure rollers are arranged linearly, and the plurality of pressure rollers are symmetrically arranged on both sides of the bottom of the mounting frame.

[0009] Preferably, the drive assembly includes two fixed frames located symmetrically on both sides of the bottom of the mounting frame. A fixed plate is fixedly connected to the top center of each fixed frame, and the top of the fixed plate is fixedly connected to the mounting frame. Connecting plates are fixedly connected to the symmetrical sides of the fixed frames, and the two connecting plates are fixedly connected to a rotating shaft. Multiple teeth are fixedly connected to the upper and lower sides of the inner walls of the fixed frames. Turntables are rotatably connected to the sides of the fixed frames that are close to each other. Multiple protrusions arranged in a circular array are fixedly connected to the turntables, and the protrusions mesh with the teeth. A connecting rod is fixedly connected to the center of the two turntables, and a motor is fixedly mounted at one end of the connecting rod. The motor is fixedly connected to the fixed frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention achieves rapid flattening of laid materials through the coordinated use of a pressure roller, a cleaning assembly, and a drive assembly. A motor drives a connecting rod to rotate, which in turn drives two turntables to rotate synchronously. The turntables' surface protrusions engage with the teeth on a fixed frame, causing the fixed frame to move horizontally and the rotating shaft to move synchronously. This allows the pressure roller to flatten the laid materials. As the roller moves, it rotates, and the top cleaning brush scrapes away the dirt adhering to its surface, preventing excessive dirt buildup later. This solves the problem of existing devices failing to flatten materials promptly when widening and adjusting roadbeds, which can lead to uneven roads and impede vehicle traffic.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, this utility model provides an auxiliary device for widening roadbed, including a material bucket 1, a feeding box 11 fixedly connected to the bottom of the material bucket 1, a feeding port 12 fixedly provided at the bottom of the feeding box 11, the material bucket 1, the feeding box 11 and the feeding port 12 being connected, a feeding inlet 13 provided on the side of the material bucket 1, a stirring assembly 14 for stirring materials being provided inside the material bucket 1, mounting brackets 2 fixedly connected symmetrically on both sides of the outer wall of the material bucket 1, and a pusher 21 fixedly connected to the top of the mounting brackets 2. The mounting frame 2 has a connecting frame 22 fixedly connected to each of the four corners at the bottom. The bottom of each connecting frame 22 is fixedly equipped with casters. The bottom of the mounting frame 2 is equipped with a flattening mechanism 3. The flattening mechanism 3 includes multiple pressure rollers 31. The center of each pressure roller 31 is equipped with a rotating shaft 311. The rotating shaft 311 passes through the pressure roller 31 and is rotatably connected to the pressure roller 31. The top of the pressure roller 31 is equipped with a cleaning component 32. The bottom of the mounting frame 2 is symmetrically equipped with drive components 33 for driving the pressure roller 31 to rotate.

[0024] Using the above scheme: When in use, the concrete or asphalt to be laid is poured into the material bucket 1 through the feed inlet 13. The mixing component 14 mixes the material to ensure uniformity. Then, the pusher 21 is manually pushed to move the entire device to the road to be paved via the bottom casters. The material is then discharged through the discharge port 12 to achieve the effect of widening the roadbed. When paving roads, the process is mostly repeated between adjacent sections. During paving, the drive component 33 drives the rotating shaft 311 to move, which in turn drives the pressure roller 31 to move horizontally to flatten the paved road. When paving other roads, the adjacent roads can also be flattened, making it widely applicable.

[0025] like Figure 4 As shown, the drive assembly 33 includes two fixed frames 331, which are located on the symmetrical sides of the bottom of the mounting frame 2. A fixed plate is fixedly connected to the top center of the fixed frame 331, and the top of the fixed plate is fixedly connected to the mounting frame 2. Connecting plates 332 are fixedly connected to the symmetrical sides of the fixed frame 331. The two connecting plates 332 are fixedly connected to the rotating shaft 311. Multiple teeth 333 are fixedly connected to the upper and lower sides of the inner wall of the fixed frame 331. Turntables 334 are rotatably connected to the sides of the fixed frames 331 that are close to each other. Multiple protrusions 3341 arranged in a circular array are fixedly connected to the turntables 334. The protrusions 3341 mesh with the teeth 333. A connecting rod 335 is fixedly connected to the center of the two turntables 334. A motor 336 is fixedly installed at one end of the connecting rod 335. The motor 336 is fixedly connected to the fixed frame 331. The teeth 333 are arranged linearly on the inner wall of the fixed frame 331, and the two teeth 333 at the symmetrically crossed ends are more protruding.

[0026] The above scheme is adopted: the drive component 33 drives the pressure roller 31, the motor 336 drives the connecting rod 335 to rotate, and then drives the two turntables 334 to rotate synchronously. The protrusions 3341 on the surface of the turntables 334 mesh with the teeth 333 on the fixed frame 331, thereby driving the fixed frame 331 to move horizontally, and driving the rotating shaft 311 to move synchronously, so that the pressure roller 31 flattens the laid material. While moving, the pressure roller 31 rotates. When the protrusion 3341 moves to the side of the protruding teeth 333, it is subject to the limiting resistance. At this time, the motor 336 rotates in the opposite direction, driving the fixed frame 331 to move in the opposite direction. At the same time, the pressure roller 31 moves and rotates synchronously in the opposite direction. This cycle is repeated to flatten the material.

[0027] like Figure 2As shown, the cleaning assembly 32 includes multiple cleaning plates 321. A cleaning brush 322 is fixedly installed at the bottom of the multiple cleaning plates 321. The cleaning brush 322 rolls in contact with the surface of the pressure roller 31. The multiple cleaning plates 321 are all located at the top of the pressure roller 31. The multiple cleaning plates 321 are arranged in an arc shape and match the arc of the pressure roller 31. Vertical plates 323 are fixedly connected to both symmetrical ends of the cleaning plates 321. The vertical plates 323 are fixedly connected to the connecting plate 332.

[0028] The above solution is adopted: the surface of the pressure roller 31 is cleaned by the cleaning component 32. The cleaning brush 322 is made of rigid material. When the drive component 33 drives the rotating shaft 311 to move, the pressure roller 31 rolls, which causes the top cleaning brush 322 to roll and scrape off the dirt adhering to the surface of the pressure roller 31, thus avoiding excessive dirt adhesion in the later stage, which is not conducive to flattening.

[0029] The working principle and usage process of this utility model are as follows: When using this utility model, the concrete or asphalt material to be laid is poured into the material bucket 1 through the feed inlet 13. The mixing component 14 mixes the material to ensure uniform mixing. Then, the pusher 21 is manually pushed to move the entire device to the road to be paved via the bottom casters. The material is then discharged through the discharge inlet 12, achieving the effect of widening the roadbed. Road paving is mostly done by repeated adjacent laying. During paving, the motor 336 drives the connecting rod 335 to rotate. The two turntables 334 rotate synchronously, and the protrusions 3341 on the surface of the turntables 334 mesh with the teeth 333 on the fixed frame 331, thereby driving the fixed frame 331 to move horizontally and the rotating shaft 311 to move synchronously, so that the pressure roller 31 flattens the laid material. The pressure roller 31 moves and rotates synchronously in the opposite direction, thus repeating the cycle to flatten the material. When the pressure roller 31 rolls, the cleaning brush 322 on the top rolls and scrapes away the dirt adhering to the surface of the pressure roller 31, so as to avoid too much dirt adhering later, which is not conducive to flattening.
