This creation is a kind of related self-propelled sprayer of what,It includes there is a vehicle frame,Wheel group is equipped with below the vehicle frame,What vehicle frame front end pivot group has the movable spraying device that can be folded,What vehicle frame is equipped with a power source and one for fluid cylinder again,This for fluid cylinder connection spraying device to supply liquid required by spraying,And the line shaft of the power source links wheel group and pressurization side Pu via clutch respectively,The pressurization helps Pu to link with for fluid cylinder; Thereby,Allow the spraying function with needed for environment and activity folds injection spray pipe,And spraying machine can be driven to walk and control simultaneously liquid spray pressure certainly by same power,To mitigate the gravity that user bears,Reach it is time saving,Laborsaving,Energy-efficient practical effect person again.本創作係有關於一種自走式噴霧機,其包含有一車架,該車架下方設有輪組,於車架前端樞組有可收合的活動式噴霧裝置,再於車架上設有一動力源及一供液筒,該供液筒連結噴霧裝置以供應噴霧所需的液體,而該動力源之動力軸經由離合器而分別連結輪組及加壓幫浦,該加壓幫浦與供液筒連結;藉此,讓該噴霧機能隨環境所需而活動收合噴霧管,且能藉由同一動力來驅動噴霧機自走及同時控制液體噴霧壓力,以減輕使用者背負的重力,達到省時、省力、又節能的實用功效者。
