Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marking line coating device and a heating burner used for drawing and marking marking lines on roads, parking lots and the like.

[0002]

2. Description of the Related Art Conventionally widely used marking line coating devices are
For example, as seen in Jikaihei 4-105111 and Jikaihei 2-5412, the paint filled in the paint tank placed on the upper part of the four-wheeled machine is heated and melted by the propane gas burner below to make it liquid. Supply to the box type paint reservoir of
There are a pre-press type that discharges from the paint discharge port provided on the side of the machine body and a back-drawing type that has a discharge port on the four-wheel inner ring side. The latter type is poor in safety because it draws while moving backward. .

Since such a conventional structure uses propane gas as a heating source, it has a large volume and a high weight.
Moreover, he was forced to equip a cylinder of dangerous goods. Therefore, since the volume occupied by the propane gas cylinder is large, there is a limit to the increase in the volume of the paint tank when viewed from the entire marking line coating device. Further, as a difficulty in use, since it is heavy, it is complicated for an operator to operate and requires skill. Moreover, it is difficult to draw a line along the marked line prior to coating. Since the four wheels pick up irregularities on the road surface, line drawing is unstable, and there are irregularities in linearity, coating thickness, and the amount of beads dispersed.

Therefore, conventionally, for the lane marking after the pavement restoration in the construction having underground work contents such as the pavement business, the pipe construction business, the electric construction business and the civil engineering business, the work has been ordered from the line construction company. However, the unit price of a specialist is high because it is a complete construction work, and in many cases it is not possible to carry out prompt construction, so the delivery of that construction was naturally delayed.

The inventor of the present invention has previously proposed Japanese Patent Application No. Hei 7-95069 to solve the above-mentioned problems, and anyone can easily and accurately perform marking line application work, and an inexpensive device. Is proposed. The structure has two wheels that support the machine during coating, and a burner that uses a fuel cylinder as a heating source under the paint tank that supplies paint to the discharge ports on the rear inner wheel side of the two wheels. It was a wire coating device. The two wheels that support the machine during coating here may be only two normal wheels, but an auxiliary wheel should be provided near the paint outlet so that the wheels do not touch the ground during coating. It also includes a structure that becomes two wheels during coating, such as a structure that escapes upward.

Further, the bead discharging device comprises an outer cylinder having a discharge guide below, and a bead case of an inner cylinder rotatably provided in the outer cylinder and having a discharge port, and a handle is attached to the inner cylinder. The bead discharge operation is synchronized with the paint application by the open / close handle. Further, the paint tank is composed of a main tank on the side of the machine body and a sub tank detachably or fixedly mounted on the main tank.

In this apparatus, the heat source for heating the paint is changed from a propane gas cylinder to a lightweight butane liquefaction cylinder and its burner, so that the machine can be supported by two simple wheels during coating. The flexibility of the two-wheel axle to the ground contact surface is great, and the paint discharge port is provided on the rear inner ring side of the two wheels. With three-point support, anyone can easily and accurately draw by constructing in the front direction. And since the paint tank is composed of the main tank on the machine side and the sub tank that is detachable or fixed above it, there is a limit to the line coating (drawing) distance in the case of only the main tank,
The coating distance is extended by the sub-tank, and the coating material is added to the sub-tank, so that the line coating distance can be greatly extended in spite of the small device.
