Equipment principle
In a closed pipe, the chain piece is used as the transmission component, and the animal material is moved along the pipeline. When conveying horizontally, the material particles are pushed by the chain in the direction of motion. When the internal friction between the material layer is greater than the external friction between the material and the pipe wall, the material moves forward with the chain piece to form a stable material flow; when the vertical conveying, the material particles in the pipe are pushed upward by the chain piece, because the lower feeding prevents the upper material from sliding, resulting in lateral pressure, so the internal friction of the material is enhanced. When the internal friction between the materials is greater than the internal and external friction between the materials and the tube wall and the weight of the materials, the materials will be conveyed upward along with the chain, forming a continuous material flow.
