When the screening mesh 12 vibrates and shakes, the block-shaped part of the asphalt concrete can pass through the upper side of the screening mesh 12 and move along the screening mesh 12 toward the end away from the first connecting plate 15 to transport the block-shaped asphalt concrete. When the screening mesh 12 vibrates and shakes, the asphalt concrete on the screening mesh 12 can be vibrated and shaken, which can avoid clogging of the asphalt concrete on the screening mesh 12 and help to use the screening mesh 12.
[0042] After the powdery or granular asphalt concrete falls to the upper side of the first conveyor belt 10, the first rotating motor 19 on the first fixed plate 3 is opened. The first fixed plate 3 can fix and limit the first rotating motor 19, so as to facilitate the stable use of the first rotating motor 19. When the first rotating motor 19 is opened, the output shaft of the first rotating motor 19 can drive the first rotating rod 5 to rotate.
