step four, a motor output shaft drives a pesticide filter vat (2) to rotate by taking an angle adjusting shaft (3) as a circle center through a transmission belt, and drives a first sector transmission gear (21) at the rear end to rotate while rotating, and the first sector transmission gear (21) drives a water discharge spray head (23) to rotate through a second sector transmission gear (22);
step five, a pair of guide strips (9) and a pipeline limiting strip (20) between the two guide strips (9) pull the transmission hose (17) so that the transmission hose (17) is wound and placed between the two guide strips (9);
step six, after the liquid is discharged through the water discharge nozzle (23), the pesticide filter screen (24) is flushed firstly, the powder on the surface of the pesticide filter screen (24) after flushing can be loosened, and along with the continuous discharge of the water discharge nozzle (23), the liquid can be converged by the device base (1) and gradually soak the pesticide filter screen (24);
starting an ultrasonic wave generating assembly (26), wherein ultrasonic waves generated by the ultrasonic wave generating assembly (26) vibrate the pesticide filter screen (24) to enable loose fragments on the surface of the pesticide filter screen (24) to fall off;
and step eight, discharging the liquid from the water outlet (12) after discharging, and discharging the liquid from the second water outlet (14) to another position.
