To provide a herbicide spreading machine that eliminates the need for mechanical maintenance, is safe, reduces production cost, and can spread the herbicide of emulsion even if being an extremely slight paddy field.SOLUTION: A herbicide spreading machine is used in a paddy field with water being spread. The herbicide spreading machine includes at least a flat-shaped vessel body made by styrene-foam, a tow thread, a tank for herbicide, a discharge pipe for discharging the herbicide, and a discharge device for opening and closing an outlet of the discharge pipe. Also, the discharge device has at least a turning shaft pivoted so as to be horizontally perpendicular to the traveling direction of the vessel body, a resistor fixed to the turning shaft, and a packing fixed to the turning shaft. Also, the discharge device is pulled or stopped by the tow thread, and thereby the resistor is turned by the resistance of water, and the outlet is opened and closed by the turning of the packing therewith to make the herbicide be spread.SELECTED DRAWING: Figure 1
【課題】機械的なメンテナンスが不要で、安全で、製作費が安価であり、かつ、極端に浅い水田であっても乳液の除草剤を散布できる除草剤散布機を提供する。【解決手段】水を張った水田で使用する除草剤散布機であって、発泡スチロール製の扁平形状の船本体と、牽引糸と、除草剤用タンクと、除草剤を吐出させる吐出パイプと、該吐出パイプの吐出口を開閉させる吐出装置と、を少なくとも備え、かつ、前記吐出装置が、前記船本体の進行方向に対し水平に直交すように枢着された回動軸と、該回動軸に固定された抵抗体と、前記回動軸に固定されたパッキンと、を少なくとも有し、かつ、前記牽引糸で牽引又は停止することで、前記水の抵抗により前記抵抗体が回動し、それに伴って、前記パッキンも回動することによって、前記吐出口を開閉して前記除草剤を散布させることを特徴とする。【選択図】図1
