[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will further introduce the present invention in detail in conjunction with the drawings.

[0030] Please refer to Figure 1-8, A road paving device for municipal road construction, including side baffles 1. A paving scraper 2 is connected between the side baffles 1. The side baffles 1 are fixed on both sides of the road. The paving scraper 2 abuts against the laid materials. Both ends of the paving scraper 2 are connected with adjusting columns 4 and moving sleeve blocks 8. On one side of the moving sleeve block 8, a transmission gear 9 and a driving motor 5 are connected in sequence. A limiting rod 3 is connected to the paving scraper 2. A gravity shaft 6 is connected to the limiting rod 3 at the rear side of the paving scraper 2. An external spiral feeder can be connected to the limiting rod 3 at the front side of the paving scraper 2.

[0031] Rectangular grooves are provided at the upper part of the side baffle 1, and convex teeth are provided at the bottom of the rectangular grooves. A chute is provided on the side baffle 1 away from the paving scraper 2, and the chute is provided on the side baffle 1 above and below the rectangular groove. By providing the rectangular groove on the side baffle 1, the transmission gear 9 can be limited, avoiding the situation that the paving scraper 2 slips off the side baffle 1 during use and slips and offsets from the side baffle 1 due to the flatness of the materials, increasing the stability of the paving scraper 2 during use. Due to the convex teeth provided on the rectangular groove, they can mesh with the transmission gear 9, enabling the paving scraper 2 to move at a uniform speed through the transmission gear 9, improving the paving effect of the materials.

[0032] The paving scraper 2 is composed of a telescopic large plate and a small plate. Cavities are provided at both ends of the paving scraper 2. The adjusting column 4 is inserted into the cavities provided in the paving scraper 2, and a scale is provided on the paving scraper 2 on the side of the cavity. Elastic blocks and adjusting holes are provided on the large plate and the small plate. By the composition of the paving scraper 2, the width of the paving scraper 2 can be adjusted according to the width of the road surface, greatly increasing the flexibility and practicality of the device. Due to the scale provided on the paving scraper 2, when the staff adjusts the height of the paving scraper 2, the two ends of the paving scraper 2 can be at the same height through the scale, avoiding the situation that the heights of the two ends of the paving scraper 2 are inconsistent, resulting in an uneven scraping surface of the materials, and improving the standard of the process.

[0033] The limiting rod 3 is fixedly connected to the paving scraper 2. Both ends of the gravity shaft 6 are respectively clamped on one end of the limiting rod 3 away from the paving scraper 2. The gravity shaft 6 abuts against the laid material. By connecting the limiting rod 3 to the paving scraper 2, the gravity shaft 6 and the external spiral feeder can be fixed. When the gravity shaft 6 is clamped on the limiting rod 3 at the rear side of the paving scraper 2 and the external spiral feeder is clamped on the limiting rod 3 at the front side of the paving scraper 2, the material can be stirred, paved, and compacted simultaneously, avoiding the need for staff to repeatedly pull the spiral feeder, the paving scraper 2, and the gravity shaft 6, saving labor costs, reducing the workload of the staff, and improving work efficiency. When only the material needs to be paved, the staff can remove the gravity shaft 6 and the external spiral feeder from the limiting rod 3. When only the material needs to be stirred and paved, the staff can clamp the external spiral feeder on the limiting rod 3 at the front side of the paving scraper 2. When only the material needs to be paved and compacted, the staff only needs to clamp the gravity shaft 6 on the limiting rod 3 at the rear side of the paving scraper 2. During use, the staff can replace the size of the gravity shaft 6 according to the width of the paving scraper 2.

[0034] The top of the adjusting column 4 extends out of the paving scraper 2. The bottom of the adjusting column 4 is rotatably connected to the paving scraper 2. The lower part of the outer wall of the adjusting column 4 is provided with an external thread, and the top of the adjusting column 4 is provided with a multi-faceted block, which is convenient for the staff to rotate the adjusting column 4. By setting the external thread on the adjusting column 4, it can be connected to the moving sleeve block 8. During use, the staff rotates the adjusting column 4 to one side through the multi-faceted block. The adjusting column 4 rotates in the paving scraper 2, driving the moving sleeve block 8 to move upward. At this time, the paving scraper 2 moves downward, and the contact area with the material increases. The staff rotates the adjusting column 4 to the other side through the multi-faceted block. The adjusting column 4 drives the moving sleeve block 8 to move downward. At this time, the paving scraper 2 moves upward, and the contact area with the material decreases.

[0035] The moving sleeve block 8 is sleeved on the thread provided on the outer wall of the adjusting column 4. The transmission gear 9 is rotatably connected to the moving sleeve block 8. A conveyor belt 7 is sleeved on the outer wall of one end of the transmission gear 9 close to the moving sleeve block 8. The outer wall of the other end of the transmission gear 9 away from the moving sleeve block 8 is connected to the cavity opened in the side baffle 1 and meshes with the convex teeth provided in the cavity. The inner wall of the moving sleeve block 8 is provided with a thread groove connected to the adjusting column 4. When the adjusting column 4 rotates, the moving sleeve block 8 moves up and down in the cavity opened in the paving scraper 2. Through the self-gravity of the paving scraper 2 and the connection method between the moving sleeve block 8 and the transmission gear 9, when the transmission gear 9 moves on the side baffle 1, the paving scraper 2 always maintains a vertical state to level the material.

[0036] One end of the conveyor belt 7 away from the transmission gear 9 is sleeved on the end of the gravity shaft 6. The transmission gear 9 drives the gravity shaft 6 through the conveyor belt 7. By connecting the conveyor belt 7 to the transmission gear 9, on the one hand, when the transmission gear 9 rotates, it can drive the gravity shaft 6 connected to the limit rod 3 to rotate through the conveyor belt 7. The gravity shaft 6 rotates and moves to compact the material, avoiding the cost expenditure of adding a power source. On the other hand, it can play a role in limiting the gravity shaft 6, preventing the gravity shaft 6 from slipping off the limit rod 3 during use and increasing the stability of the gravity shaft 6.

[0037] One end of the transmission gear 9 away from the moving sleeve block 8 is fixedly connected to the output shaft of the drive motor 5. The drive motor 5 abuts against the side baffle 1 on the side away from the paving scraper 2. The model of the drive motor 5 is a common model on the market and will not be elaborated here. The drive motors 5 on both sides of the paving scraper 2 are controlled by one switch, which can start and stop the drive motors 5 on both sides synchronously. The drive motor 5 is connected to an external power source. During use, the staff connects the drive motor 5 to the external power source and starts the drive motor 5. The drive motor 5 drives the transmission gear 9 to rotate. The transmission gear 9 meshes with the convex teeth on the side baffle 1 and moves on the side baffle 1. The transmission gear 9 drives the paving scraper 2 to move through the moving sleeve block 8. The paving scraper 2 levels the material. At the same time, the transmission gear 9 drives the gravity shaft 6 to rotate through the conveyor belt 7.

[0038] A fixing frame 10 is sleeved on the outer wall of the drive motor 5. The end of the fixing frame 10 is slidably connected to the chute opened on the side baffle 1. By connecting the fixing frame 10, on the one hand, it can support and limit the drive motor 5, avoiding the situation of self-rotation of the drive motor 5 when it starts. On the other hand, by connecting the fixing frame 10 to the side baffle 1, when the drive motor 5 moves, the fixing frame 10 can limit the drive motor 5 and cooperate with the movement of the transmission gear 9 at the same time.

[0039] Working principle: During use, the staff first fixes the side baffles 1 on both sides of the construction road, connects the paving scraper 2 to the side baffles 1, and engages the gravity shaft 6 and the external spiral distributor on the limit rod 3 according to the usage requirements. The staff holds the adjusting column 4 and rotates the adjusting column 4 according to the paving depth. The moving sleeve block 8 moves in the paving scraper 2 to adjust the paving scraper 2 to an appropriate height, and then the drive motor 5 can be started. The drive motor 5 drives the transmission gear 9 to rotate. The transmission gear 9 meshes with the convex teeth on the side baffle 1 and moves on the side baffle 1. The drive motor 5 drives the fixing frame 10 to move on the side baffle 1 through the movement of the transmission gear 9. The transmission gear 9 drives the paving scraper 2 to move through the moving sleeve block 8. The paving scraper 2 levels the material. At the same time, the transmission gear 9 drives the gravity shaft 6 to rotate through the conveyor belt 7 to compact the material.

[0040] Only some exemplary embodiments of the present invention have been described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
