Excrement pollution-free treatment device for pig breeding

The invention discloses an excrement pollution-free treatment device for pig breeding, and belongs to the technical field of excrement treatment. An excrement pollution-free treatment device for live pig breeding comprises a driving mechanism and a treatment mechanism; airflow enters an inner cavity of a communication transverse pipe through a communication cavity, a communication bent pipe is of a U-like structure, and the airflow moves towards the two sides of the communication bent pipe; at the moment, the airflow enters an inner cavity of a treatment box, the two-way airflow carries out opposite flushing, and in the airflow opposite flushing process, the vortex is in opposite rotation directions, so that the vortex converges into opposite-impact airflow, the two-way opposite-impact vortex improves the flowing of the airflow in the device, and the opposite airflow generated at intervals due to reciprocating rotation of the driving motor can enable the excrement to be treated to be subjected to aerobic ferm
