Description

An orchard spraying machine

technical field

The utility model relates to the technical field of orchard pesticide application, in particular to an orchard pesticide application machine.

Background technique

At present, the method of spraying pesticides in orchards is to apply artificial electric sprayers. Artificial electric sprayers usually include chemical liquid tanks, spraying pipelines, booster pumps, and spraying rods. During the spraying process, fruit farmers need to hold and shake the spraying rods. In order to make the liquid evenly spread on the whole fruit tree.

However, the size of the fruit tree crown is not consistent from bottom to top. Usually, the width of the middle part of the fruit tree crown is the largest, while the width of the bottom and top is relatively small. Therefore, the air resistance of the middle part of the fruit tree crown is the largest. The air resistance is relatively small. For this reason, sprayers need to frequently adjust the output pressure of the electric sprayer to ensure that the internal branches and leaves can be sprayed evenly.

Since the spraying rod needs to change the spraying position frequently, even if the spraying pressure is often adjusted, it still cannot match the resistance of the branches and leaves at the corresponding position. Drift of the medicine solution and the mismatch between the application amount and the demand of the tree canopy. Uneven application of the medicine is likely to have a negative impact on the fruit trees, and the drift of the medicine solution is likely to cause harm to the health of the fruit growers.

Therefore, how to uniformly apply the medicine to the crown of the fruit tree and avoid the drift of the medicine liquid is a technical problem urgently needed to be solved in this field.
