The present invention relates to a rotary chemical injection device for a plastic greenhouse, which comprises blower motors mounted on both sides of a lower body and connected to inclined blower pipes having a spray nozzle installed thereon respectively; a ″���″ shaped cover body having a central bolt and a connection bolt installed in the center of the planar surface; an upper body having a chemical water level detector, a twin timer, a relay and a relay timer arranged thereon and connected with a wire respectively; a bearing insertion part formed on one side of a crank installation stand and fixated with a nut by inserting the central bolt projected from the center of the planar surface of the ″���″ shaped cover body so as to support the lower body horizontally; and the connection bolt connected to a through hole of a crank arm of a crank device mounted on the other side so as to interlock the lower body according to the driving range of the crank arm. The air introduced to a compressed air hose is connected to the spray nozzle through a solenoid valve in the cover body, and the chemical introduced through a chemical hose dipped in a chemical container is connected to the spray nozzle so as to be sprayed to both sides. The upper body is hung on a support stand of a plastic greenhouse so that the chemical is automatically sprayed by compressed air of a compressor and operation of the switch of a control unit in a wide range. |
