One driving end of the double-shaft motor is fixedly connected with a semi-bevel gear, and the semi-bevel gear meshes with the first bevel gear and the second bevel gear in turn.

[0008] The swinging assembly can make the nozzles swing reciprocally around the axis of the water pipe, and pump the liquid medicine to the water pipe, the square water pipe, the flow dividers and the nozzles during the swinging process.

[0009] Furthermore, a support plate is fixedly installed on the inner wall of the hollow column, and the water pipe passes through the support plate and is rotatably connected with it.

[0010] Further, a medicine storage barrel and a water pump are fixedly installed on the upper surface of the trolley, and the water inlet end of the water pump is communicated with the inner bottom of the medicine storage barrel. The water outlet end of the water pump is communicated with a medicine delivery hose, and the other end of the medicine delivery hose penetrates through the outer wall of the hollow column and is communicated with a water pipe.

[0011] Further, the other driving end of the double-shaft motor is connected with a stirring assembly. The stirring assembly includes a worm fixedly connected to the other driving end of the double-shaft motor. A worm gear is arranged on the upper surface of the medicine storage barrel.
