Abstract

The invention discloses an auxiliary conveying device for upper and lower layers of sand and gravel, which comprises a mounting frame, a hopper, and a corrugated pipe. A positioning ring is fixed at the discharge port of the corrugated pipe, and a downwardly extending bracket is fixed on the mounting frame. The adjustment mechanism of the inclination of the ring; the bracket includes a plurality of vertical rods, and the multiple vertical rods are evenly arranged with the axis line of the hopper as the center line. The adjustment mechanism includes a sliding seat that can move up and down relative to the vertical rod, and a winding roller. , control shaft, control block, steel cable with one end fixed on the winding roller and the other end fixed on the positioning ring, the driving handle fixed to the winding roller, the adjustment component for adjusting the height of the sliding seat, the connection between the steel cable and the positioning ring The points are evenly distributed along the circumference of the positioning ring. In the conveying device designed in this scheme, sand and gravel can directly enter from the hopper and come out from the bellows. By controlling the unfolded length of multiple steel cables, the position of the positioning ring can be adjusted, thereby changing the position of the bellows outlet, which is convenient and fast. material.
