A catch engagable with a catch pivot ring for capturing and releasing a stunning rod moveable along a longitudinal axis in a pneumatic animal stunner for stunning an animal. The catch comprises a plurality of arcuate sections substantially forming a cylinder, each arcuate section having a forward end and a rearward end. The catch includes an inner wall toward the longitudinal axis and an outer wall away from the longitudinal axis. The catch includes a flange at the rearward end of the arcuate section extending outwardly directly from the outer wall and away from the longitudinal axis and a lip at the forward end of the arcuate section extending inwardly from the inner wall and toward the longitudinal axis. Each of the arcuate section flanges is engagable with an inner lip of the catch pivot ring allowing the arcuate sections to pivot about the catch pivot ring inner lip.

A bolt tool system includes a tool housing, a bolt guide, a bolt, an activator, a pin casing, and a lock pin. The bolt guide is attached to the tool housing. The bolt is moveably received within the bolt guide for movement between a retracted position and an extended position. The activator is moveably received on the bolt guide for movement between a safe position and a fire position. In the fire position, the bolt is moveable from the retracted position to the extended position. The pin casing has a passage in communication with an aperture formed in the activator. The lock pin is slidably received within the pin casing. The lock pin is moveable between a disengaged position and an engaged position in which the lock pin retains the activator in the fire position.

A pneumatic animal stunner employing a stunning rod includes a catch mounted within the housing for alternately holding and releasing the stunning rod. A catch piston is disposed adjacent the catch on a side away from the longitudinal axis, and is in sliding contact adjacent the catch end portion and out of contact with the catch body portion. The catch piston slides between a first position urging the catch end portion toward the stunning rod longitudinal axis in the hold position, thereby holding and preventing the stunning rod from being driven forward, and a second position permitting the catch end portion to move to the release position away from the stunning rod longitudinal axis releasing and permitting the stunning rod to be driven forward. Valves control air flow to cause the catch piston to move between the first and second positions.

A poultry stun detection system is designed for using with a poultry slaughter platform, wherein the poultry stunning detection system includes at least: a first camera device, a second camera device, a network transmission device, and a computer processing device. The poultry stun detection system utilizes visual devices to immediately determine whether the stunned poultry still has perception in real time, and employs the YOLOv4 deep learning model to enhance the recognition accuracy of whether the poultry has lost its consciousness after stunning.
