In daily farming activities, agricultural drones are used more and more in the prevention and control of pests and diseases. The nozzle clogging caused by the problem of the liquid medicine caused the flying hand to have a headache. The nozzle clogging not only affected the efficiency of the operation, but also greatly reduced the operation effect and could not achieve the expected effect.

Today I will introduce some methods to avoid the blockage of the plant protection drone nozzle.

1.Filter the liquid in advance

Experienced friends know that some of the chemicals are extremely thick and even precipitate, which increases the chance of the nozzle being blocked and affects the working efficiency. If the medicine box filter is blocked, it is necessary to dump the medicine back into the dispensing barrel and clean the medicine box, which is a waste of time, so it is necessary to filter the liquid in advance.

To prevent clogging, filter or high-density stockings can be used to filter the liquid. It should be noted that the gap of the filter should not be too large or too dense, and the gap will be large, which will not play a good filtering effect. If the gap is too small, the filtration will be too slow and will affect the efficiency. Therefore, it is necessary to use a suitable filter to maximize the maximum. Reduce the occurrence of blockages.

2.Pesticide secondary dilution method

The second dilution method is also known as a two-step preparation method. First, the pesticide preparation is diluted into a mother liquid or a mother powder with a small amount of water or a diluted carrier, and then diluted to a desired concentration.

The “second dilution method” enables the pesticides with low solubility to be fully dissolved, the distribution to be more uniform, the precipitation of pesticides to be avoided, and the clogging of the nozzles to be reduced. In particular, when the amount of certain pesticides is extremely small, the "second dilution method" can uniformly prepare the medicament, thereby improving the utilization rate and the use effect.

3.Four parts need to be cleaned in time

That is, the medicine box, the nozzle, the strainer, and the decompression valve.

Long-term operation will form a ring of sticky film (especially powder) on the outer layer of the filter. The decompression valve will also precipitate the drug. These deposits or membranes will block the spray system and affect the spraying effect. Therefore, the above components should be cleaned in time after each operation to remove the sediment in the parts to avoid clogging.

what? You said that your nozzle is blocked, what should you do? Don't rush to change the nozzle, don't rush to clean it in the wrong way. In the next issue, Xiaobian will tell you that the plant protection drone nozzle is blocked and how to clean it properly. Stay tuned!
