Abstract: Meat pigeon breeding is an emerging farming industry with a high economic benefit. There are some fundamental problems that need to be addressed, such as the fact that artificial feeding work takes a lot of labor power when breeding in a large scale, the low level of feeding precision, and the high waste forage rate, which is also a disadvantage existing in meat pigeon breeding at present. An automated feeding device for meat pigeons which is suitable for three ladder cages was designed in order to solve the problems of automated feeding for large-scale breeding of meat pigeons. The automated feeding device was mainly composed of feeding troughs, a control box, travel switches, three-phase asynchronous motors, wheels, a driveline, and a frame. The frame mainly uses 40 mm× 40 mm× 4 mm square steel welded together. Feeding troughs were mounted on each layer of the frame respectively. The track was made up of 40 mm× 40 mm× 4 mm angle iron, which was bolted to the ground. The automated feeding device for meat pigeons was equipped with cast iron wheels mounted in the bottom of the frame on both sides. The travel switches were located in the outside of underlying level support of the frame and used to control the stroke of the automated feeding device for the meat pigeons. The driveline selected sprocket and chain to transmit output dynamic of the three-phase asynchronous motors to the wheels. The transmission ratio was 1:1. The control system of the device was mainly composed of a frequency converter, the travel switches, time relays, AC contactors, an air switch, buttons, and an indicator light. In the device's control system, a frequency converter was adopted to control the speed of two three-phase asynchronous motors; the travel switches were used as a position detecting component; a time relay was used to set the running time and residence time in the feeding process; and AC contactors were used to control the start and stop of the frequency converter. The control system realized stroke control of the automated feeding device with high precision such as moving, stopping, and reversing. The prototype of the automated feeding device for meat pigeons was designed and tested for the stroke precision and feed wastage rate. And experimental results showed that the stroke precision of the system was controlled at more than 98%. The feed wastage rate was controlled at less than 1%. In conclusion, the automated feeding device for meat pigeons was applicable to factory farming, and had a good stability; feeding.
