Spraying machine

A spraying machine propelled by a pulse jet engine mainly comprises a pesticide liquid box, a machine frame, an oil tank, a pesticide conveying tube, a battery as well as a hand air pump. The utility model is characterized in that: the other end of the pesticide conveying tube connected with the pesticide liquid box is connected with a jet pipe of the pulse jet engine. The utility model adopts the advanced pulse jet engine with higher spraying speed, thereby not only simplifying machine structure and manufacture technique, but also more importantly improving greatly the atomization of pesticide liquid particles, improving spraying distance and providing an effective tool for controlling damage by disease and insect in high arbors and forests. The utility model has the advantages of pesticide particle thinning, long spraying distance, high efficiency, low pesticide consumption, good insert killing effect, low cost and labor intensity, easy operation as well as convenient use and maintenance, thereby being a novel pesticide application machine with bright prospect and wide application.
