Non-linear chaotic vibrating bar

The invention relates to a non-linear chaotic vibrating bar, belongs to non-linear chaotic vibrating bars applied to industries such as buildings, food, medicine and the like and mainly aims to solve the technical problems that vibrational excitation of an existing vibrating bar cannot comprehensively reach a material area, materials are not vibrated densely and stirring is not uniform. According to the technical scheme, the non-linear chaotic vibrating bar comprises an electric motor, a transmission flexible shaft and a chaotic bar head, wherein the electric motor is connected with a driving end of the transmission flexible shaft, a rotating shaft is arranged in an inner cavity of the chaotic bar head, one end of the rotating shaft is fixed at an opening of the inner cavity of the chaotic bar head, an eccentric block is arranged at the other end of the rotating shaft, the tail end of the transmission flexible shaft is connected with the fixed end of the rotating shaft, an L-section curve of the inner wall of
