An automatic locking mechanism for the doors of H-shaped, tiered chicken cages has been developed, facilitating mechanized chick handling.

The automatic locking mechanism for H-shaped tiered chicken cages has recently undergone a technological upgrade, delivering an innovative design that balances efficiency and safety for large-scale poultry farms. By optimizing the cage-door opening-and-closing mechanism, this innovation enables seamless mechanized integration with chicken-handling operations. Traditional cage doors require frequent manual operation during handling, which is inefficient and can easily startle the flock; in contrast, the new automatic locking system features a dual-design approach—spring return combined with mechanical limit stops. When a chicken-handling device (such as a robotic arm or conveyor belt) contacts the cage door, the locking mechanism automatically releases, allowing the door to open smoothly; once handling is complete, the door automatically returns to its closed position and locks securely under spring action, eliminating the need for any manual intervention throughout the entire process.
This design is specifically optimized for the vertical space layout of tiered chicken cages, enabling unified management of cage systems ranging from 3 to 12 tiers. For instance, in a 12-tier ultra-high-density rearing setup, the automated locking mechanism works in tandem with a bottom-mounted pull-out cage grid: when it’s time to catch the birds, simply activating the conveyor system allows the broilers to automatically slide down the inclined cage grid onto the conveyor belt, thereby eliminating stress responses and feather damage that can result from manual handling. In addition, the locking mechanism is constructed from hot-dip galvanized steel, offering corrosion resistance for more than 20 years—matching the service life of the cage structure itself and reducing long-term maintenance costs.
Technical tests demonstrate that this system can increase chicken-handling efficiency in individual poultry houses by 40%, while its robust mechanical design ensures a failure rate of less than 0.5%, thereby providing reliable support for the smart and intensive transformation of poultry farms.
