The driving member is slidably connected to the cross bar, and the feeding hopper is provided with an annular groove, and the annular groove is provided with a plurality of protrusions along the circumference. The two ends of the cross bar are located inside the annular groove, and the feeding hopper is provided with a heating member. By adopting the above technical solution, the driving member drives the cross bar to rotate, the annular groove limits the cross bar, and the protrusion enables the cross bar to drive the vertical bar to move. The movable block at the lower end of the vertical rod is located at the outlet of the feeding hopper. The movable block moves up and down with the vertical rod to clear the paving materials at the outlet of the feeding hopper to prevent the materials from being blocked. The vertical rod drives the connecting rod to rotate. The plug block is located in the spiral groove. The spiral groove has a limiting effect on the plug block, so that the movable cylinder moves vertically along the length of the slide groove. The two toggle rings toggle the materials inside the feeding hopper in the vertical direction to further prevent the materials from being blocked. The rotating motor drives the toggle ring to rotate. The triangular block rotates with the toggle ring to toggle the asphalt materials near the toggle ring to further prevent the materials from being blocked.

[0004] In actual applications, the existing paver hopper consumes a lot of energy to prevent the hopper from being blocked. It should be improved to increase the energy utilization rate, so the anti-blocking structure needs to be modified. Utility Model Content
