The utility model relates to a self-propelled sprayer driving structure which is arranged in a track, which is arranged in a planting site with a C-shaped track setting, and a wheel frame is arranged on the top of the sprayer, and a steel cable is assembled in the wheel frame, so that The steel cable is surrounded by two large and small rollers fixed on the frame, and a chain gear is coupled with the large roller and the sprocket provided by the spindle of the transmission motor； thus, when the transmission motor is started During the operation, the chain of the mandrel is moved by the chain gear of the large roller, so that the wire rope surrounding the large and small rollers is horizontally moved, so that the wheel frame can move according to the C-shaped track, which is a sprinkler. The spraying work with regular displacement is simple installation, less failure, automatic spraying, reducing the artificial effect, and thus improving work efficiency.一種架設在軌道中之自走式噴灑器帶動構造，係指架設在具有C型軌道設置的栽種植場地中，在噴灑器頂上位置係設有一輪架，在輪架中並組裝著鋼索，使鋼索得環繞在兩固定於架上的大、小兩滾輪之中，並由一鍊齒條得以鍊合著大滾輪及傳動馬達的心軸所設之鍊齒輪；如此一來，當啟動傳動馬達的運轉時，得使心軸的鍊動大滾輪的鍊齒輪，以致帶動環繞在大、小兩滾輪的鋼索呈水平式移動，進而使輪架得循C型軌道做移動，是噴灑器遂而以規律性的位移來做噴灑工作，是具安裝簡便、故障少、自動化噴灑、減少人工作用，進而提昇工作效率者。
