Description

Powder pesticide sprayer {POWDERED PESTICIDE SPRAYER}

The present invention relates to a powder pesticide sprayer, and more particularly, to a powder pesticide sprayer capable of rapidly spraying the powder pesticide in a wider radius using a strong spraying power operated by wind pressure.

Conventionally, when applying granulated or powdered pesticides or powdered fertilizers to crops or soil, farmers directly touched and fertilized them, so they were directly affected by pesticides harmful to the human body.

In particular, when fertilizing pesticides or fertilizers through manual labor, labor and time were consumed excessively, and productivity was also greatly reduced. Considering the reality of rural areas where labor is greatly shortened, this was a very irrational work.

Therefore, in recognition of these problems, a'reservoir of a manual pesticide sprayer' has been proposed in Korean Utility Model Publication No. 20-0244214. The above technology has been proposed to improve the problem of spraying powdery pesticides or fertilizing granular fertilizers using a hand. It is attached to the tip of a tubular handle connected with a hose to a distributing reservoir for pesticides/fertilizers. The spreading plate attached by knowledge is blocking the tip of the tubular handle, and at the same time, the arm holding the tubular handle is struck, and at the same time, when the lever is pressed with the thumb, it tilts back and opens the tip of the tubular handle to open the tip of the tubular handle, Immediately after spraying granular fertilizer and spraying or fertilizing pesticides, when the thumb is removed from the lever, the spreading plate immediately returns by the return spring and blocks the tip of the tubular handle, so that no more pesticide spraying or fertilization is possible.

However, such a conventional manual pesticide sprayer was able to eliminate the induction of various skin diseases caused by the pesticide components to some extent, but the spraying distance was short and the spreading range was relatively narrow, and the operation of the sprayer was performed manually. As a result, there was a problem that the work efficiency was greatly reduced.
