Poultry carcass on-line automatic grading device

The invention relates to the technical field of poultry carcass grading equipment, and discloses a poultry carcass on-line automatic grading device which comprises a return type conveying feeding machine, a detection device frame whole is installed in one side of the return type conveying feeding machine, and the outer portion of the detection device frame whole is movably sleeved with a movable frame. The outer side of the return type conveying feeding machine is fixedly connected with a removing device. According to the on-line automatic grading device for the poultry carcasses, on-line grading can be completed through one-time manual hanging without unhooking; through data analysis, the yield of rear-end carcass processing is increased, and the difference of carcass quality in different growth cycles can be reversely deduced to provide data reference for front-end breeding; the labor cost is saved, errors caused by manual material arrangement are avoided, and automatic positioning is achieved through the h
