The present invention is equipped with a fan back to the engine and the drug in a liquid of agricultural and livestock bangyeokgi be drug barrel mounted thereon to diffuse spray the drug stored in a drug through a strong wind that occurs going it is up to the fans of the engine back to the farm by supplying the air pressure in the fan inside of the stored drug barrel to mix uniformly the drug give rise, of course, also prevent the drugs inside the back flow of the air supply pipe for supplying air and at the same time drug through the engine to a discharge pressure of a medicament to be configured on the drug through a portable agricultural and livestock bangyeokgi the drug accumulated in one thing both sides of the deflection unit while plight to look like trousers to spray the drug in a stable condition by lowering the center of gravity to be smoothly discharged to the negative sides, bottom inside drug bottle the jimyeo connection ventilation so that air pressure entering arising from the pan and the top of the bend in n-shape protruding upward in the n-type upper middle configuring the damper passage increasing the air supply pipe is configured by drilling the upper one in one place through the pores of the damper configuration, and end the center and the left and right sides three place its end of the air distribution hoses are distributed, including to the air supply is that the air is injected configured to reach the Yang - di through the floor to mix the drug stored inside drug bottle and to act to give, wherein the configuring the control valve to form exhaust holes has closed the lid of the medicine barrel to circulate the air at the same time as adjusting the air pressure of the inside, the drug barrel so that the engine left and right sides sagging consists of a pants shape, and is connected to one injector at the bottom of one side constitutes a discharge hole for coupling the drug supply hose to feed the medicines, by connecting the remaining one side of the inner bottom is not formed ball the exhaust ball and discharged to the discharge hose and configure the drug inside the drug is discharged through the exhaust side of the ball is not struck emissions formed on the other side.
