Description

Technical Field

[0001] The utility model relates to the technical field of asphalt recovery, in particular to asphalt pavement recovery and regeneration equipment. Background Art

[0002] Asphalt pavement recycling refers to the process of processing the asphalt mixture of the old asphalt pavement into a mixture that meets the technical requirements of the asphalt pavement, and then re-paving it as a new asphalt pavement. In order to obtain the old asphalt mixture, special equipment is often required to crush and recycle the old asphalt pavement.

[0003] For example, in the patent document with patent publication number CN209958201U, a road breaking device for facilitating the recycling of waste asphalt is disclosed, which includes a breaking roller and a conveyor belt. A hydraulic rod is connected to the left side of the breaking roller, and a breaking hammer is installed below the hydraulic rod. A rotating motor 1 is arranged below the breaking roller, a rotating roller is connected below the rotating motor 1, and a rotating steel sheet is arranged below the rotating roller. The conveyor belt is installed on the right side of the breaking roller, and a workbench is installed on the upper right side of the conveyor belt. A servo motor is installed above the workbench, and an asphalt recovery bin is installed on the lower right side of the servo motor, and a hydraulic pump is arranged on the upper right side of the asphalt recovery bin.

[0004] According to the existing technical literature, although the crushing device can crush the old asphalt pavement through the crushing hammer, rotating steel sheet and rupture roller, since the bottom position and angle of the conveyor belt are fixed, it is impossible to effectively move the crushed asphalt pavement fragments to the conveyor belt by simply relying on the rotating steel sheet and the rupture roller. Once the fragments accumulate between the rotating steel sheet and the rupture roller, it is easy to cause the two to get stuck, thereby affecting the normal operation of the device and even causing damage to it; secondly, the crushed asphalt pavement fragments are large and small. After they are sent to the asphalt recovery bin through the conveyor belt, it is necessary to wait until the number of fragments in the bin is stored to a certain level before screening them. Since the number of fragments is large at this time, the screening workload will be heavier.

[0005] To this end, the utility model optimizes and improves the problems in the prior art that the crushed asphalt fragments cannot be effectively scooped up and the size differences of the recovered fragments are large. A new type of recovery equipment is proposed that can effectively scoop up asphalt fragments and pre-screen them, so as to better solve the problems in the prior art. Utility Model Content

[0054] Specific working principle:

[0055] First, the telescopic rod ends of each electric cylinder 5 are controlled to extend synchronously, so that the connecting plate 23 moves downward, and then the electric pick 24 and the second cutting roller 26 move downward until they are pressed against the old asphalt road surface, and then the old asphalt road surface is shattered by the impact of the electric pick 24, and then the large fragments are cut into smaller fragments by the cutting spikes on the circumferential outer surface of the second cutting roller 26. At the same time, the telescopic rod of the hydraulic cylinder 10 is controlled to retract, and the left end of the shovel plate 7 is driven to swing counterclockwise to the lower right around the rotating rod 8 until the shovel teeth 9 are pressed against the road surface after the asphalt is crushed, so as to shovel the asphalt fragments and send them to the first circular conveyor belt 13. Under the clockwise rotation of the first endless conveyor belt 13, the asphalt fragments scooped up by the shovel plate 7 and the shovel teeth 9 are transported to the first storage bin 1, and finally fall to the second endless conveyor belt 16.
