The first driven wheel 29 drives the connecting shaft 211 to rotate the driving bevel gear 2122 inside the fixed arm 212. During the rotation of the driving bevel gear 2122, the driven bevel gear 2123 can be driven to rotate the main shaft 2124. During the rotation of the main shaft 2124, the mounting part 21a1 acts on the swing arm 21a2, and the gear 21a3 at the other end of the swing arm 21a2 can follow the guidance of the gear ring 21a4 to make the linkage part 21a5 connected below start to move, and the linkage part 21a5 makes the slide plate 21a6 reciprocate in the guide part 21a10, and the toggle plate 21a9 also starts to perform synchronous circular motion and reciprocate itself. During the movement, the toggle bar 21a8 and the toggle plate 21a9 connected at the bottom start to stably toggle the asphalt inside the guide box 21 to avoid blockage and increase the falling speed; If it is necessary to change the falling speed of the material port at the other end, the crank 23 can be turned, and the crank 23 can move the threaded rod 241 to move the sliding member 24 in the support 22. The limit rods 25 at the upper and lower ends of the sliding plate 24 can move with the belt 26, and the belt 26 can contact the second driven wheel 210, and the second driven wheel 210 starts to move. During the movement, the toggle mechanism 21a at the corresponding position of the other material port in the material guide box 21 can start working.
