Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to improvement of a burner used in a road marking line coating device for coating marking lines such as white lines on a road surface.

(Prior Art) In this type of coating device, a paint container with a slit metal fitting attached to a hand truck is slidably contacted on the road surface.
2. Description of the Related Art A slit-type coating device is widely used in which molten coating material (coating material) is caused to flow out from a slit-shaped opening of a slit fitting and is coated on a road surface. Then, in order to heat the paint container to maintain the paint at a constant temperature and allow the paint to flow out smoothly from the slit fitting, a gaz burner is arranged toward the outer wall surface of the paint container, and propane gas is supplied to the gas burner. Burning.

(Problems to be solved by the invention) However, since this gas burner is installed close to the road surface and travels with the truck, dust and dirt near the road surface are likely to adhere to the gas outlet of the burner nozzle, and dust and so on. When the gas cylinder is replaced in a high-volume environment, the sand dust that has entered through the attachment / detachment port of the hose easily reaches the nozzle and is clogged in the fuel ejection hole of the nozzle. For this reason, the nozzles are clogged to cause a combustion failure or stop, the heating of the paint container is insufficient, and the fluidity of the paint is deteriorated. This breakdown becomes a particularly serious problem when the work is performed by cutting off the traffic for a certain period of time.

This invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a burner for a road marking line coating device that can quickly and easily eliminate the clogging of the burner nozzle.

(Means for Solving the Problems) However, the burner of the present invention is a nozzle in which the wire is inserted into the fuel gas ejection hole of the nozzle body with a clearance, and the wire end protruding from the outer end surface of the nozzle body is bent. A burner for a road marking line application device, characterized in that it penetrates through a combustion cylinder connected to the main body and projects laterally, and a turning operation portion for the wire is provided at the projecting end.

(Operation) In the burner of the present invention, since the wire is inserted into the fuel gas ejection hole of the nozzle body with a clearance, the fuel gas is ejected to the outside through the clearance and the fuel is carried out without any trouble. Further, since the above-mentioned clearance exists, the wire can be freely rotated in the gas ejection hole, and if the wire is pivoted by operating the pivoting operation portion protruding to the outside of the combustion cylinder with a finger or the like, the fuel gas is ejected. The foreign matter adhered in the hole or in the vicinity of the entrance / exit of the hole can be separated from the nozzle body, and the clogging of the nozzle can be easily eliminated.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is a nozzle body, one end of which is connected to a propane gas cylinder (not shown) through a pipe 2 and a combustion cylinder 3 is connected to the other end, 4 is a fuel gas ejection hole penetrating the nozzle body 1, It is composed of a small-diameter portion 4a on the gas ejection side and a large-diameter portion 4b having a slightly larger diameter following the small-diameter portion 4a. Reference numeral 5 denotes a wire such as a stainless wire, which has a wire diameter (for example, 0.8 mm) smaller than the inner diameter (for example, 1,3 mm) of the small diameter portion 4a of the fuel gas ejection hole 4. The wire end portion 6 of the wire 5 protruding from the inner (fuel supply side) side surface 1a of the nozzle body 1 is bent at a substantially right angle to form a retaining piece that engages with the inner end surface 1a. The outside of the nozzle body 1 of the wire 5 (fuel injection side)
The wire end portion 7 projecting from the end face 1b is also bent substantially orthogonally, penetrates the air intake 8 of the combustion cylinder 3 and projects laterally, and the projecting end 9 has a metal pipe I and a plastic pipe covering the metal pipe B. A knob-shaped rotation operating portion 10 is formed by inserting and crimping.

In the burner 11 having the above structure, the fuel gas is supplied to the pipe 2
When the fuel gas is ejected from the small diameter portion 4a of the ejection hole 4 and ignited by an appropriate ignition device such as a hand burner, the fuel gas is burned in the combustion cylinder 3 and the flame is radiated to the outside of the combustion cylinder 3. Then, the paint container (not shown) is heated. When foreign matter such as dust or dust adheres to the inside of the fuel gas ejection hole 4 or the entrance / exit of the hole, and combustion becomes unsuccessful, the rotating operation 10 is operated with fingers or a thin rod, and the arrow in FIG. The wire 5 is rotated within the fuel gas ejection hole 4 as indicated by. As a result, the foreign matter separates and falls from the nozzle body 1, and the separated foreign matter in the fuel gas ejection hole 4 is also blown out by the fuel gas, so that the foreign matter can be removed.

The present invention is not limited to the above-described embodiment, and the turning operation portion 10 may be formed by bending the protruding end 9 of the wire 5, for example. In the above embodiment, the wire end 6 protruding from the inner end surface 1a of the nozzle body is bent to bend the inner end surface 1a.
Since it is engaged with a, it has the advantage of scraping and removing foreign matter near the inner end face 1a, but this wire end 6 remains straight without being bent or the wire 5 is enlarged. You may make it cut | disconnect as it is a straight line in the diameter part 4b, and do not let it protrude from the inner end surface 1a.

(Effects of the Invention) As described above, according to the present invention, a device having an extremely simple structure in which a wire is inserted into the fuel gas ejection hole of the nozzle body can remove foreign matter when the nozzle is clogged quickly and easily. It is possible to prevent the nozzle clogging in the road marking line coating device and to solve the accident.
