The Bolong automatic egg collection and laying box is composed of a laying box body, a variable-speed egg collection platform, an egg conveying channel, a chicken drive and a control system. The bottom net of the laying box is designed with a standard 8 degree inclination angle, covering a special soft bottom pad, and installed in the chicken house through a modular combination; the egg aisle is installed at the lower end of the slope bottom pad with a conveyor belt inside. The chickens enter the laying box to lay eggs, and the eggs roll off the bottom pad and enter the egg belt in the egg aisle. The eggs can be transported to the egg collection platform by running the egg belt regularly. The operator completes the collection and preliminary sorting at the platform.
