The tiered chicken cage manure removal machine is a high-efficiency manure-clearing device specifically developed for modern multi-tier H-shaped chicken cage farming systems. The equipment adopts a modular design, with each independent cage group equipped with its own dedicated manure-removal conveyor belt. These belts are manufactured from high-strength engineering plastics or galvanized steel plates, offering excellent corrosion resistance and aging durability. In terms of the drive system, the machine can be configured either as a single-axis centralized drive, in which a single main drive shaft synchronously powers multiple conveyor belts, or as a grouped-drive control system tailored to the scale of the farm, where each cage group is fitted with an individual motor to enable precise start–stop control and variable-frequency speed regulation. This flexible drive configuration not only meets the cost-effectiveness requirements of small and medium-sized farms but also supports the intelligent management needs of large-scale operations.

　　The equipment safety protection system employs a dual safeguard mechanism: core components are equipped with overload protection devices. When the manure-removal belt becomes jammed by foreign objects or experiences excessive load, pressure sensors immediately trigger power-off protection, causing the drive motor to shut down automatically within 0.3 seconds and effectively preventing equipment damage such as belt rupture and drive shaft deformation. In addition, the control system incorporates a built-in current-monitoring module that continuously tracks the motor’s operating current; if the current rises abnormally above the set threshold, the system not only cuts off the power supply but also activates an audible alarm to alert operators to promptly troubleshoot the fault.

　　The surface of the manure-removal belt is treated with a special process to create a smooth, mirror-like finish, reducing the coefficient of friction by more than 40% compared with conventional conveyor belts. This design allows chicken manure to slide off naturally under gravity, reducing residual buildup by 65% compared with standard equipment. Combined with an adjustable-angle rubber scraper assembly, it enables secondary, thorough cleaning. The scraper is made from food-grade silicone, ensuring effective cleaning while protecting the belt surface; its unique curved design efficiently removes stubborn contaminants lodged in the belt’s grooves.

　　In terms of noise reduction, the equipment incorporates multiple sound-insulation measures: an external soundproof enclosure for the drive motor reduces noise by 8 to 10 decibels; rubber vibration-damping pads are installed on the transmission components to minimize noise generated by mechanical vibrations; and high-performance polymer wear strips are used on the manure-removal belt’s running track to prevent direct metal-on-metal friction and the resulting harsh squealing. Actual measurements show that the equipment’s operating noise remains consistently below 55 decibels—roughly equivalent to the volume of normal conversation—well below the national environmental noise standards for livestock farms. This minimizes disturbance to the chickens’ rearing environment, helping to maintain their stable physiological rhythms and consistent egg-production performance.
