Materials are collected; Step 3. As the conveyor belt (1) continues to transport the operation frame (4), the transmission pin (703) of the connecting plate (702) on the operation frame (4) and the slope (803) on the push plate (802) Through the counteracting action of the inclined plane (803) and the transmission pin (703), the driving connecting plate (702) and the sliding plate (501) are forced to move. During the movement of the sliding plate (501), through each sleeve (601) The guiding effect of the sliding rod (602) makes the stressed skateboard (501) move toward the operating frame (4) and drive the outer movement. During the movement, the skateboard (501) is no longer in the operating frame (4). Inside, at this time, the asphalt material with smaller particle size inside the operation frame (4) and below the slide plate (501) falls from the gap between the slide plate (501) and the operation frame (4). The falling particles are collected by the collection vehicle. Collect asphalt materials with smaller diameters; After completing the recycling and transmission process, the asphalt materials are layered according to the particle size and discharged in sequence; Step 4: During the transportation of the operation frame (4) through the conveyor belt (1), the protrusions (1002) on the installation plate (1001) are in turn against the side walls of the side plate (301), and the protrusions (1002) ) and the friction between the side wall of the side plate (301) drive the mounting plate (1001) and the mounting shaft (1102) to rotate; During the rotation of the installation shaft (1102), each knocking head (1104) on the drive plate (1103) is sequentially offset against the outside of the operation frame (4), so that the inside of the operation frame (4) and the operation frame (4) The sliding plate (501) vibrates due to force. By vibrating the sliding plate (501), the filtering efficiency of the filter holes (502) on the sliding plate (501) for falling asphalt materials is improved.
