Liquid jetting apparatus

Abstract

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.

Description

technical field [0001] The present invention relates to a new type of liquid spraying device, for example, a liquid spraying device that sprays a liquid such as cleaning fluid to oil residue accumulated inside a fuel tank to make it flow, and in particular relates to an indication equipped with a mechanism capable of displaying and changing the inclination angle of a nozzle barrel device. Background technique [0002] Conventionally, there have been many liquid spraying devices for cleaning the inside of the fuel tank. For example, Japanese Patent Publication No. 4-33275, Japanese Patent Publication No. 58-9674, Japanese Patent Publication No. 59-36281, Japanese Patent Publication No. 4-110158, Japanese Patent Publication Japanese Patent Laying-Open No. 56-15855, Japanese Patent Publication No. 58-23435, etc., all supply cleaning liquid at high pressure, and use the supply pressure to rotate the impeller to rotate or rotate the nozzle part for spraying cleaning liquid.

Problems solved by technology

[0004] However, using the first operating lever and the second operating lever, the mechanism for setting the swinging rotation range of the spraying cylinder at the front end of the rotating cylinder of the rotating oil supply cylinder and detecting the range is very complicated. It is difficult to change the starting position of the swinging rotation of the spray cylinder
