Description

약제 분사기{A drug sprayer}A drug sprayer

본 발명은 약제분사기에 관한 것으로 보다 구체적인 것은, 약제공급호스로부터 공급되는 약제를 연결관에 수용하고, 연결관에서 분사노즐로 전달하되, 약제분사관이 연결관에서 회전되게 하여 약제의 분사방향을 자유롭게 변화시키면서 약제를 분사할 수 있게 하여 약제공급호스의 꼬임을 방지하고, 회전되는 약제분사관의 연결부에서 약제가 누출되지 않게 연결부를 형성하여 사용이 편리하고, 안전이 보장되게 한 것이다.The present invention relates to a drug injector, and more specifically, accommodates the drug supplied from the drug supply hose in the connecting pipe, and delivers it to the injection nozzle from the connecting pipe, but rotates the drug injecting pipe in the connecting pipe to change the spraying direction of the drug. By allowing the drug to be sprayed while changing freely, the drug supply hose is prevented from being twisted, and the connection part is formed so that the drug does not leak from the connecting part of the rotating drug injection pipe, so that it is convenient to use and safety is ensured.

일반적으로 농가에서는 농작물의 병충해를 예방하기 위하여 방제용 약제를 분사하게 되는데 종래의 약제분사기는 약제분사관이 약제를 연결하는 연결관에서 회전되지 않으므로, 약제의 분사방향을 변경시킬 때는 분사기 전체를 회전시키면서 약제를 분사해야 하는데 이때 연결관에 연결된 약제공급호스도 함께 회전하게 되어 약제공급호수가 꼬이게 되므로 수시로 이를 풀어주어야 하는바, 약제 살포작업이 원활하게 이루어지지 못하고, 작업피로도가 증가하는 불편이 있었다.In general, farmhouses spray pesticides to prevent pests and pests in crops. Conventional chemical sprayers do not rotate in the connecting pipe connecting the chemical spraying pipe to the chemical. At this time, the drug supply hose connected to the connecting pipe also rotates, causing the drug supply hose to be twisted, so it must be loosened frequently.
