Abstract

A tiles or bricks shoveling device includes a body having front wheels and rear wheels, and a handle is connected to a rear end of the body. A motor is connected to the body and drives a circular member by its eccentric shaft. A block is fixed to the body and two posts movably extend through the block. A front board and a rear board are connected to the front and rear ends of the posts. Two springs are connected to the two posts to return the rear board. A shoveling blade is connected to the front end of the front board such that when the motor is activated, the posts are moved reciprocally and the shoveling blade moves linearly back and forth with the front board to shovel the tiles and bricks up.
