When the two moving wheels 14 on the same side move closer to each other, the spacing between the two moving wheels 14 on the same side decreases, and vice versa. The distance between the two moving wheels 14 on the same side depends on the row spacing of two adjacent rows of corn, until the two moving wheels 14 on the same side can move on the outside of two adjacent rows of corn, further achieving the purpose of facilitating the adjustment of the spacing of the moving wheels 14 according to the row spacing of corn planting;

[0041] During operation, the device needs to be pushed to move, and the staff will walk between two adjacent rows of corn plants, and the support base 1 will be located above the corn plants. Since a hose of sufficient length is connected between the water outlet of the booster pump 3 and the hose connector 26, the hose can adapt to the lifting and lowering of the circular tube 7, and then the liquid medicine inside the medicine box 2 is pumped into the interior of the circular tube 7 through the hose through the booster pump 3, and then enters the interior of multiple medicine distribution pipes 8, and then is sprayed on the corn plants through multiple atomizing nozzles 9, so that the corn can be sprayed with medicine.
