The invention relates to a liquid jetting apparatus. A nozzle on the front end of a liquid supply cylinder, sinking from an oil tank, is used for jetting washing oil or other cleaning liquid to clean oil residues accummulated in the oil tank. The nozzle sinks along the axis in the liquid supply cylinder (60) for receiving the driving force of a driving mechansim (10). A rotary cylinder portion (62) on the front end of the liquid supply cylinder rotates around the axis via a rotary shaft (50), and a nozzle cylinder (70) rotates on the front end of the rotary cylinder portion, allowing the inclined end to be a rotary surface. The liquid jetting apparatus is characterized in that the rotary shaft (50) is composed of a rotary shaft center (51) and a rotary shaft cylinder (52) for surrounding the rotary shaft center; the rotary cylinder portion (62) rotates via the rotary shaft cylinder (52) and the nozzle cylinder (70) rotates via the rotary shaft center (51); the apparatus is provided with the first planet gear mechanism (81) and the second planet gear mechanism (82) of a central gear, wherein the first planet gear mechanism and the second planet gear mechanism are driven respectively by the rotary shaft cylinder (52) and the rotary shaft center (51) to rotate, and the first planet gear mechanism and the second planet gear mechanism are connected with a common annular inner gear (83) to form an indication mechansim (80); the inclined angle of the nozzle cylinder (70) is displayed on the indication mechansim corresponding to the axis; and a switch mechanism (90) is operated through a switch operation device that can be arranged on the position of an indication disc for displaying a set rotary angle, so that the rotary driving direction of a driving source is reverse. Therefore, the rotary inclined angle of the liquid nozzle can be easily set. |
