Automatic positioning device for moving plate type feeder

The utility model belongs to the technical field of plate-type feeders, and particularly relates to an automatic positioning device for a movable plate-type feeder, which comprises a transport frame and support legs, a feeding device is arranged on the left side of the transport frame, a positioning device is arranged in the middle of the transport frame, and a buffer blanking device is arranged on the right side of the transport frame. According to the automatic positioning device for the moving plate type feeder, the feeding units are mutually spliced to form the plate type conveying belt, the plate type conveying belt is driven by the driving unit to operate and feed materials, more convenience and rapidness are achieved, the plate type conveying belt is stopped and positioned through the positioning device, impact force generated during discharging is avoided, and the feeding efficiency is improved. When discharging is carried out, mineral aggregate firstly falls onto a buffer plate, the impact force gene
