LIQUID SPRAYING DEVICE FOR GREENHOUSE

To provide a liquid spraying device for greenhouse in which a mechanism is simplified and can be inexpensively acquired, and which is light weight and can be easily handled.SOLUTION: A liquid spraying device 1 comprises: rail support members 2 which are a right and left pair and attached to a transverse beam B of a greenhouse on an upper side; a rail 3 which is supported to a rail support part at a lower part of the rail support members in an orthogonal direction to the transverse beam B; and a spraying machine 4 for self-traveling along the rail for spraying a liquid such as an agrochemicals which is sent through a transfusion hose 5. A Travel body 6 of the spraying machine 4 comprises a front and rear pair of drive wheels 65 and driven wheels 66 rolling on the rail 3. A multi-head spraying nozzle 8 is supported in a horizontal direction at a lower part of a lifting pole 7 which suspends from the travel body 6 and which can be freely extended/contracted. The transfusion hose 5 is coupled to the mult-head spraying nozzle 8 through a pump P from a tank T which is at an external side of the greenhouse, and advances into the greenhouse according to movement of the spraying machine 4.SELECTED DRAWING: Figure 2 【課題】機構が簡易で安価に得られるると共に、軽量で取り扱いが容易な温室内用液体散布装置を提供する。【解決手段】液体散布装置１は、上部で温室の横梁Ｂに左右一対取り付けられるレール支持部材２と、それの下部のレール支持部に横梁Ｂと直交方向に支持されるレール３と、これに沿って自走しながら輸液ホース５を介して送られる農薬等の液体を散布する散布機４とを具備する。散布機４の走行体６は、レール３上を転動する前後各一対の駆動車輪６５と従動車輪６６とを具備する。走行体６から垂下し伸縮調整自在の昇降ポール７の下部に水平方向に多頭噴霧ノズル８が支持される。輸液ホース５は、温室外のタンクＴからポンプＰを介して多頭噴出ノズル８に接続され、散布機４の移動に応じて温室内へ進出する。【選択図】図２
