[0002] In order to make the nutrients of waste such as poultry and livestock manure easily absorbed by the land, people usually air-dry the waste such as poultry and livestock manure, crush it, and then apply it to the land. Chicken manure air-drying equipment is often used for air-drying chicken manure. This equipment realizes automatic air-drying of chicken manure, which can greatly improve the air-drying efficiency.

[0003] However, during the transmission of manure on the conveyor belt, the manure has a certain weight and will cause the conveyor belt to sink. Since the gap between the upper and lower layers of the conveyor belt is 20-25cm, the upper layer of the conveyor belt will sink and droop into the gap under the action of gravity, causing resistance to the movement of the manure belt and damaging the belt, affecting the stability of the manure transportation work. Therefore, how to design and install a device at the front end of the air-drying equipment that can keep the conveyor belt in a taut state at all times is an urgent problem that technical personnel in this field need to solve.
