Building material belt conveying device

The utility model relates to the field of building construction, in particular to a building material belt conveying device which comprises a base, and self-locking universal wheels are fixedly installed on the periphery of the bottom of the base. The belt conveying mechanism used for conveying concrete is mounted at the top of the base; by arranging the height adjusting assembly, when the concrete conveying height is adjusted, a servo motor drives a lead screw to rotate, the lead screw is in threaded connection with a moving seat to drive the moving seat to move transversely, and when the moving seat moves, a second fixing rod at the top of the moving seat is driven to move synchronously; and a second fixing rod at the bottom of the conveying shell is driven to move up and down through conduction of a linkage rod, then the second fixing rod is matched with a supporting rod and a first fixing rod, the height of one side of the conveying shell is adjusted, and the purposes that the concrete conveying height ca
