With advances in sprinkler and drip irrigation technologies, integrated water and fertilizer systems have been widely adopted in my country, increasing the workload associated with mixing pesticides and fertilizers. To ensure that pesticides and fertilizers are thoroughly mixed and dissolved before spraying, a method using powered mixing not only reduces labor intensity but also prevents worker poisoning from prolonged pesticide exposure.

To be precise, the input path of the power flexible shaft is at a different height than the mixing barrel, resulting in bends in several parts. Due to the high-speed transmission of power, the flexible shaft at the bends is prone to breakage, resulting in a short service life of the equipment. Summary of the Invention
