The tiered feeder is a modern farming equipment specifically designed for Type A tiered chicken houses, with its core advantage being the enhancement of farming efficiency through a scientifically optimized feeding method. The equipment is available in two mainstream drive configurations: gantry-type and chain-driven. The gantry-type system achieves precise positioning via rail-guided movement, while the chain-driven system relies on gear transmission to ensure operational stability. Farmers can flexibly select the most suitable configuration based on the structural characteristics of their chicken house.

　　During the feeding process, a feed cart equipped with a dedicated drive mechanism moves at a constant speed along the length of the chicken house, with its travel speed adjustable within the range of 0.5 to 2 meters per minute to match the flock’s feeding rhythm. The feed hopper features a conical design and is fitted with an internal screw agitator, which prevents feed from caking and ensures uniform discharge. Feed is dispensed in precise, measured amounts through adjustable-angle discharge pipes, each outlet being equipped with a flow-control valve that enables accurate portioning of 50 to 500 grams per feeding, thereby meeting the nutritional requirements of chicks, growing pullets, and mature chickens at different stages of development.

　　The equipment features a specially designed intelligent adjustment system that automatically optimizes feeding parameters based on the chickens’ age: from 1 to 14 days, chicks are fed small amounts frequently; from 15 to 42 days, the amount per feeding is increased; and for mature chickens aged 43 days and older, a timed, portion-controlled feeding program is activated. This dynamic adjustment mechanism improves feed conversion efficiency by 15% to 20%, effectively reducing waste caused by overfeeding. According to actual calculations, a flock of 10,000 chickens can save approximately RMB 12,000 in annual feed costs.

　　In terms of safety protection, the feeder is equipped with a dual safeguard system: the spill-prevention device combines silicone sealing strips with negative-pressure suction technology to keep the spill rate below 0.3%; the end-limit switch features both infrared sensing and mechanical braking for double protection—when the feeding cart reaches the end of its travel, the system completes deceleration and braking within 0.2 seconds, preventing the equipment from colliding with the chicken cages. In addition, the equipment is fitted with an emergency stop button and an overload protection device, ensuring that power can be immediately cut off in the event of an emergency to safeguard both farm personnel and the flock.

　　The equipment is constructed entirely from 304-grade stainless steel, with key components undergoing specialized anti-corrosion treatment, ensuring a service life of over 10 years even in farming environments with 85% relative humidity. Its modular design reduces installation time to less than three hours, while routine maintenance requires only weekly cleaning of the feed hopper and inspection of the drive components, significantly lowering labor costs. These features make the tiered feeder an essential piece of equipment for modern poultry farms seeking to enhance production efficiency.
