The invention belongs to the technical field of concrete vibration, and particularly relates to a movable concrete mechanical vibrating device. Aiming at the problems that when concrete is vibrated, adevice needs to be continuously pushed manually to move, and manpower is consumed, the following scheme is proposed, the movable concrete mechanical vibrating device comprises a top plate, two firstmounting blocks which are symmetrically distributed are fixed to the outer wall of the bottom of the top plate, first rectangular grooves are formed in the outer wall of the bottom of the first mounting blocks, first sliding rails are fixed to the inner walls of the left sides and the right sides of the first rectangular grooves, sliding blocks are slidably connected to the inner walls of the first sliding rails, and first movable plates are fixed to the outer walls of the bottoms of the sliding blocks. Through the arrangement of a third motor, a rotating disc, a connecting rod, a mounting sleeve and a fixing plate, an output shaft of the third motor drives the rotating disc to rotate so as to drive the upper end of the connecting rod to do circular motion, the lower end of the connectingrod drives the mounting sleeve to move up and down, so that a vibrating rod continuously moves up and down in concrete, the honeycomb pitted surfaces with different depths of the concrete are vibratedand compacted, the vibrating efficiency is high, and manpower is saved.
