Attitude adjusting mechanism of belt opening machine

Abstract

The invention discloses a posture adjusting mechanism of a belt opening machine, which is used for solving the problems of poor limit capability of posture mechanism adjustment and large required installation space during operation of the belt opening machine. The posture adjusting mechanism integrally comprises a movable end, a rack, a large arm, a large arm mounting seat, a pitching oil cylinder, a pitching oil cylinder mounting seat, a turnover oil cylinder mounting seat and a turnover oil cylinder. Through the reasonable arrangement of the relative position relation of all the parts and the telescopic movement of the pitching oil cylinder and the overturning oil cylinder, the extension distance of the movable end relative to the rack can be short, meanwhile, the large arm can pitch up by 24-26 degrees and pitch down by 45-47 degrees, and the movable end can be overturned by 30-120 degrees; therefore, the space size of the posture adjusting mechanism is reduced, and meanwhile the operation capacity of the belt opening machine in complex terrains is improved.
