After the spraying operation is completed, the operator can choose to continue to supplement the water source into the water storage tank 1 or discharge the residual liquid through the drain pipe at the bottom of the water storage tank 1, and simultaneously, the device can be transferred to other operation points through the universal wheels 35.
