Bulk material and strip-lump material separation device of belt conveyor

The utility model relates to a material conveying device, in particular to a bulk material and strip-lump material separation device of a belt conveyor. A grating enclosing board is arranged at a position which is distant from the discharge end of an upper belt conveyor. The enclosing frame of the grating enclosing board is an inverted-U-shaped frame which consists of a top fence board and two side guard boards which are perpendicularly fixed at the two ends of the top fence board, wherein the opening of the inverted-U-shaped frame faces towards the belt conveyor. A grid mesh is fixed in a cavity at the lower end part of the inner wall of the enclosing frame. The width of the grid mesh is smaller than the width of the belt of the upper belt conveyor. The grid mesh is slightly inclined rearwards. The front end part of the grid mesh is lower than the upper plane of the belt conveyor. The two side boards of the enclosing frame are respectively fixed with the upper end parts of two supporting bars. The lower ends
