Referring to Figure 1-2, a vibratory road roller that is easy to adjust includes a road roller body 1, the front end of the road roller body 1 is provided with a horizontally installed frame 2, a cylindrical vibration chamber 3 is installed on the frame 2, and the road roller body 1 A support base 4 is installed on the rear side of the support base 4, and the lower end of the support base 4 is rotatably connected with a threaded cylinder 6 with both ends open through the bearing base 5. The threaded cylinder 6 is threadedly connected with a threaded post 7, and the end of the threaded post 7 away from the support base 4 passes through. A pressure plate 8 is fixedly connected to the lower end of the threaded barrel 6, a pressure roller 9 is installed on the pressure plate 8, a driven gear 10 is fixedly sleeved on the outer barrel wall of the threaded barrel 6, and a drive motor is fixedly connected to the lower end of the support base 4. 11 (the rotation direction of the output end of the drive motor 11 can be changed by controlling the current direction, which is the prior art, and will not be repeated here), the output end of the drive motor 11 is connected with a driving gear 12 through a coupling, and the driving gear 12 meshes with the driven gear 10, starts the driving motor 11, the driving motor 11 drives the driving gear 12 to rotate according to the direction of the current, and drives the threaded barrel 6 to do corresponding work in the bearing seat 5 through the driven gear 10 meshing with the driving gear 12. Rotation, because the lifting column 17 can only move in the vertical direction, so that the pressure plate 8 and the threaded column 7 will not rotate with the rotation of the threaded barrel 6, and when the threaded barrel 6 rotates, the threaded column 7 is rotated according to the rotation of the threaded barrel 6. Drive the pressure plate 8 to make a corresponding upward or downward movement, and then drive the pressure roller 9 to make a synchronous upward or downward movement. When the pressure roller 9 is not used, the height of the pressure roller 9 is raised to prevent the pressure roller 9 from contacting the road surface. The surface of the pressing roller 9 is protected, which improves the service life of the pressing roller 9 .

An end of the threaded column 7 away from the pressure plate 8 is fixedly connected with an anti-detachment column 13, a bearing 14 is fixedly sleeved on the column wall of the anti-detachment column 13, and a slider 15 is symmetrically and fixedly connected to the annular side wall of the bearing 14.
