Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides as Figures 1-4A leveling device for laying plastic runways as shown in the figure includes a fixed bottom plate 1.

A crushing hob 4 and a grinding roller 5 are respectively installed on the side walls of the two support main shafts 3. Support bases 6 are respectively installed on the bottom outer wall of the fixed bottom plate 1. A bidirectional threaded rod 7 is rotatably connected to the support base 6. A support block 8 is connected to the outer surface thread of the bidirectional threaded rod 7. The thread directions at both ends of the bidirectional threaded rod 7 are opposite, so that when the bidirectional threaded rod 7 rotates, the two support blocks 8 move in opposite directions. An L-shaped base 9 is installed on the bottom outer wall of the support block 8. A guiding support shaft 10 is respectively slidably clamped on the L-shaped base 9. An L-shaped scraper 11 is installed at one end of the guiding support shaft 10. A support spring 12 is arranged on the side wall of the guiding support shaft 10. Driving motors 13 are respectively installed on the top outer wall of the fixed bottom plate 1. A first driving pulley 14 is connected to the output end of the two driving motors 13. A first driven pulley 15 is installed at one end of each of the two support main shafts 3. The first driving pulley 14 is connected to the first driven pulley 15 through a transmission belt. The first driving pulley 14 on the same side is connected to the first driven pulley 15 on the same side, so that the driving motor 13 can drive the corresponding support main shaft 3 to rotate. A first rotating motor 18 is installed on the top outer wall of the fixed bottom plate 1. A second driving pulley 20 is connected to the output end of the first rotating motor 18. A second driven pulley 19 is installed at one end of the bidirectional threaded rod 7. The second driven pulley 19 is connected to the second driving pulley 20 through a transmission belt. When using this device, first place the device on the ground so that the crushing hob 4 and the grinding roller 5 can contact the ground. Then push the device forward. The driving motor 13 on the same side as the crushing hob 4 drives the crushing hob 4 to rotate, so that the crushing hob 4 can break up large-volume protrusions. After pushing the device forward for a certain distance, the first rotating motor 18 drives the second driving pulley 20 to rotate, so that the bidirectional threaded rod 7 can rotate. The bidirectional threaded rod 7 can drive the two L-shaped bases 9 to move outward from the fixed bottom plate 1 at the same time, and the support spring 12 can drive the L-shaped scraper 11 to press against the ground. When the L-shaped base 9 moves, the L-shaped scraper 11 can scrape the broken impurities to both sides of the fixed bottom plate 1, which can prevent the broken impurities from affecting the subsequent grinding of the ground by the grinding roller 5, thereby improving the efficiency and effect of the device for leveling the ground.

[0022] In this embodiment, support vertical plates 16 are respectively installed on the bottom outer wall of the fixed bottom plate 1.

Support columns 23 are respectively installed on the bottom outer wall of the I-shaped lifting plate 22. A universal wheel is installed at one end of the support column 23 away from the I-shaped lifting plate 22. The universal wheel facilitates the movement of the device.

A second rotating motor 26 is installed on the top outer wall of the cross-shaped fixing plate 25. The output end of the second rotating motor 26 is connected to the ball screw 21. The second rotating motor 26 drives the ball screw 21 to rotate, so that the ball screw 21 can drive the I-shaped lifting plate 22 to lift, thereby adjusting the height of the fixed base plate 1, and further adjusting the height of the crushing hob 4 and the grinding roller 5 from the ground.

[0024] The working principle of this utility model: This utility model is a leveling device for laying plastic runways. When in use, by pushing the device forward, at the same time, the large-volume protrusions can be broken by the rotation of the crushing hob 4. After pushing the device forward for a certain distance, the first rotating motor 18 drives the driving pulley two 20 at its output end to rotate, so that then the L-shaped base 9 can be driven to move to both sides of the fixed base plate 1 through the bidirectional threaded rod 7, and the support spring 12 can drive the L-shaped scraper 11 to press against the ground. When the L-shaped base 9 moves, the L-shaped scraper 11 can effectively scrape the broken impurities to both sides of the fixed base plate 1, thus avoiding the impurities from affecting the subsequent grinding of the ground by the grinding roller 5, and further facilitating ensuring the grinding efficiency and effect of the device on the ground.
