Abstract
Disclosed is a mining material trolley with a telescopic and turnover lateral wall. The structure of the mining material trolley with the telescopic and turnover lateral wall is composed of three parts, namely a material trolley body for raw ore, movable lateral wall part, and a turnover lead screw and nut part. A movable lateral wall is telescopic so as to enable the height of the lateral wall to descend. About linear materials, after the lateral wall descends to a certain height, materials are pushed down from the trolley for unloading. The height of the movable lateral wall gradually rises (descends) along with loading (unloading) of the materials, trolley loading (trolley unloading) is convenient. After the movable lateral wall descends to the lowest height and is turned over to be opened completely, trolley loading and unloading from outer side of the movable lateral wall is more labor-saving, highly-efficient, and safer than trolley loading and unloading from two ends of the material trolley body for the raw ore or materials turning over a fixed lateral wall. Triangle brackets at two ends of the mining material trolley are exchanged from the stationary type connection into plug type connection, after the movable lateral wall is dismantled. Convenience is brought to trolley unloading of materials among the triangle brackets and the fixed lateral wall.
