Poultry seedling constant temperature transport vehicle: fully enclosed intelligent temperature control and air circulation system, the vehicle equipped with refrigerated truck manufacturing technology, a molding plate splicing structure. The interior and exterior materials of the compartment are glass steel plates with 8cm thick polyurethane insulation plates sandwiched in the middle. The compartment is equipped with refrigeration unit equipment (optional dual-temperature unit or additional heating system), which is evenly distributed in the compartment and mixed with cold air through the shunt channel to fully ensure that the temperature in the compartment meets the physiological requirements of chickens. Both sides and front and rear panels of the compartment are designed with ventilation windows according to the volume of the compartment (the windows can be opened or closed according to the ambient temperature), and a skylight with strong exhaust fan function is opened at the top, which can provide sufficient fresh air and oxygen for the compartment. Small ventilation windows (blinds) can also be installed at the front and rear of the compartment according to customer requirements. On the way of vehicle driving, natural wind will blow into the pipeline through the window and enter the compartment through the air outlet, without blowing chicken seedlings directly. The temperature monitoring equipment is installed in the compartment, which can be monitored intuitively in the cab and adjusted at any time. A water heating device is installed at the bottom of the compartment body, so that the temperature in the compartment body can be ensured to be warm as spring in cold winter, and the compartment body can truly achieve a constant temperature effect. The other compartment can be customized according to user requirements. The seedling transport vehicle has the functions of heating, refrigeration, ventilation, oxygen supply, moisture retention and the like, can create a comfortable living environment for poultry chicks such as chickens, ducks and geese, and effectively ensures the survival rate of poultry chicks. This vehicle is mainly used for specialized transportation of chicks, ducklings, pigeons and birds, with high transportation efficiency and large loading capacity.
