Introduction to Crawling Manure Cleaning Technology

Over recent years, the standardized scale of commercial laying hen farming has transitioned to using crawling manure cleaning systems, especially in multi-tier cage operations. This technology effectively reduces the moisture content of manure, lowers harmful gas emissions, enhances manure quality as raw material, and significantly boosts biosecurity in chicken houses. The method has gained widespread adoption in chicken house renovation projects, particularly during manure clearing system upgrades.

Ideal Application Scenarios

This method is best suited for:

• Farming Models: Closed chicken houses or those with windows.
• Cage Configurations: 4 to 8-tier stacked cage systems or 3 to 5-tier step cage systems.
• Ventilation Systems:
  • Summer: Wet curtain + fan longitudinal ventilation cooling system.
  • Winter: Mixed ventilation mode with side window or eave air intake.

Installation and Operational Details

The crawling manure cleaning system includes:

1. Key Components:

   • Inside the Barn: Longitudinal crawling manure cleaning equipment.
   • Outside the Barn: Transverse crawling manure cleaning equipment and inclined conveyors.
   • Core Parts: Motors, reducers, chain drives, active/passive rollers, and crawling belts.

2. Material Selection:
   Crawling belts are a critical cost factor. High-quality, high-strength belts resistant to expansion and contraction are essential for durability.

3. Configuration:

   • Stacked Cage Systems: Longitudinal belts are installed under each layer.
   • Step Cage Systems: A single manure belt is installed 10-15 cm above the ground beneath the bottom cage layer.

Key Operational Advantages

1. Efficient Moisture Reduction:

   • Chicken manure drops directly onto the cleaning belt.
   • Longitudinal airflow within the barn dries the manure, reducing its water content significantly.

2. Enhanced Biosecurity:

   • Manure exits the barn without contact with the ground, reducing contamination risks.
   • Granulated manure facilitates easier post-processing and lowers ammonia levels in the barn.

3. Streamlined Process:
   The system ensures a seamless transfer of manure from the barn to trucks or organic fertilizer plant pipelines.
