At this time, the threaded rod 5 is rotated so that the roller 6 provided at the bottom contacts the ground. The pushing device is moved forward so that the roller 6 rolls on the surface of the roadbed. When the roadbed is uneven, the support rod 3 is lifted by the limit block 4, thereby generating ups and downs, which is convenient for the operator to record the roadbed, thereby filling or reducing the material on the road surface.

By providing a threaded rod 5 on the inner wall of the limit block 4, when it is necessary to measure the roadbed thickness, the measuring mechanism provided on the inner wall of the positioning sleeve 2 is adjusted to make the support rod 3 After adjusting to a suitable position, the threaded rod 5 is rotated to make the roller 6 arranged at its bottom contact the ground, and the roller 6 is rolled on the surface of the roadbed by moving the pushing device forward. When the roadbed is uneven, the support rod 3 is lifted by the limit block 4, thereby generating ups and downs, which is convenient for the operator to record the roadbed, thereby filling or reducing the road surface. By setting a screw rod 7 on the top of the base 1, the moving block 8 arranged on the outer wall is adjusted by rotating the screw rod 7, so that the moving block 8 drives the shock absorbing bin 9 arranged on one side to move to a suitable position, and by setting a spring 10 on the inner wall of the shock absorbing bin 9, a spring 10 is set on one side of the spring 10.
