Concrete vibration device

The invention discloses a concrete vibration device which comprises two supporting frames. A fixing frame is arranged between the two supporting frames. Two vibration motors are arranged at the top of the fixing frame; the output end of each vibration motor is connected with a vibration rod through a flexible shaft; the outer side of each flexible shaft is sleeved with a hose. Lifting mechanisms are arranged at the tops of the fixing frames; a lifting plate is arranged at the output end of the lifting mechanism; a first mounting groove is formed in the bottom of the lifting plate; a first bidirectional lead screw is rotationally connected into the first mounting groove; the first bidirectional lead screw is in threaded connection with two first sliding blocks. A first mounting seat is arranged at the bottom of each first sliding block; the hoses are fixedly connected to the first mounting seat; a driving mechanism used for driving the first bidirectional lead screw to rotate is arranged on one side of the lif
