Abstract

The utility model belongs to the technical field of grinding equipment, and relates to an agricultural harvesting machinery serrated knife efficient grinding device which comprises a serrated knife disc fixing frame and a serrated knife disc rotationally arranged on the serrated knife disc fixing frame, a serrated knife is installed on the serrated knife disc, and a grinding machine frame is detachably installed on the serrated knife disc fixing frame. A horizontal pushing base plate is arranged on the grinding machine frame in a sliding mode, an angle grinder acting on the tooth cutter disc is connected to the horizontal pushing base plate through an angle grinder fixing base, and a corner locking rod capable of adjusting the inclination angle of the angle grinder fixing base is arranged on the horizontal pushing base plate. The horizontal pushing base plate is arranged on the grinding rack in a sliding mode, and the distance between the angle grinder and the serrated knife is controlled to be adjusted. And the inclined grinding angle of the angle grinder relative to the serrated knife can be adjusted through the corner locking rod, the adaptability to the serrated knife can be improved, and then the stability of the grinding quality is guaranteed.
