Abstract

PURPOSE:To enable a white line drawing machine to draw a white line and to spread beads by one worker and, at the same time, to enable the white line drawing machine to draw a white line after four hours after the reconstruction of a road. CONSTITUTION:A caster 3 and wheels 7 and 7a are mounted to the body 1 to form a tricycle type white line drawing machine, and melted paint is stored in a shoe 16 and is applied to a road from a grinding port 18 thereof. Beads supplied from a bead box 22 are uniformly spread thereon through a bead spreading box 29.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to a white line drawing machine for drawing white lines such as straight lines, curved lines and characters on a pavement surface.

[0002]

2. Description of the Related Art A conventional white wire drawing machine is made on the premise of straight drawing, and a shoe in which paint is melted is placed on a vehicle body.
The white line is drawn by flowing paint from the shoe onto the pavement surface. Further, when the beads are sprinkled on the white line, conventionally, the worker manually sprinkles the beads.

[0003]

Therefore, there are the following drawbacks.

A. In particular, it is difficult to draw curved lines and letters, and skill is required for this work, so there is a shortage of skilled workers. Therefore, the restoration of the paved road surface work may be delayed,
This has led to soaring construction costs.

B. When beads are sprinkled during drawing, one person draws white lines, and then another person sprinkles beads, because it needs to be done immediately after applying the paint. For this reason, at least two workers are required for white line drawing involving bead spreading.

C. The beads are not uniform when sprinkled.

The object of the present invention is to draw straight lines,
Even if you are not an expert, you can freely draw curves and letters and you can draw white lines with one worker including bead scattering, by proposing a white drawing machine that can spread beads evenly is there.

[0008]

The structure of the white wire drawing machine according to the present invention is as follows.

[0009] A caster mounting plate is attached to the front center horizontal direction of the vehicle body and is rotatably attached to the mounting plate, wheels mounted on both sides of the rear portion of the vehicle body, diagonally upward from the rear portion of the vehicle body. A handle attached toward, a lock lever that fixes the caster straight or controls it freely, a guide bar that is foldably attached to the front and rear of the vehicle body, a gas burner is attached to the outside, and paint is put inside to use a gas burner. It can hold the heated and melted paint, forms a paint outlet on the bottom, and can be opened and closed by the shoe set on the vehicle body so that it can be moved up and down by a shoe set lever. And the shoe shutter opening / closing lever that opens and closes this shoe shutter. -Open and close the bead box with beads inside, the bead sprinkling box for sprinkling the beads supplied from this bead box on the coating surface, and the bead shutter at the spout opening provided at the bottom of the bead sprinkling box. A white wire drawing machine consisting of a bead shutter open / close lever.

[0010]

[Function] A solid paint (for example, 0.67 kg / m) is put in the shoe and the gas burner is ignited.
Dissolve in about a minute. The fuel of the gas burner uses LPG. The road surface to be white-lined should be thoroughly cleaned so that there is no sand, etc., and guide markings for white-line drawing will be performed on it. Next, beads are put in the bead box to prepare for work, the gas burner is stopped, and the LPG gas hose is removed from the hose connection port.

Next, the caster of the front wheel is set on the guide marking, the guide bar is tilted forward to align the tip with the guide marking, and the shoe set lever is operated to lower the shoe to bring it closer to the road surface. To open the shoe shutter, open the slide-out port, and let the paint flow down to the road surface from here. In this state, while pushing the handle, the white line drawing machine is slowly moved forward (for example, 1 m / 4 sec) along the guide marking to perform white line drawing.

In the above work, in the case of straight line drawing, the caster is locked by the lock lever so that the caster does not wobble. On the other hand, in the case of curve drawing and characters,
Operate the lock lever to make the casters free while allowing the direction to change freely.

Next, when the beads are sprinkled at the same time, the bead is supplied from the bead box to the bead sprinkling box by operating the bead opening / closing lever at the same time as the paint is made to flow down from the sliding outlet. Sprinkle beads from the spout of the box on the coated surface. When the specified white line has been drawn, operate the shoe shutter open / close lever to close the sliding door, operate the bead open / close lever to stop the beads, and then operate the shoe set lever to lift the shoe upward and lift the guide bar. Fold back from above and move the white wire drawing machine into place. The paint remaining in the shoe can be reheated and reused.

Since the present invention is constituted as described above,
It has the following effects.

A. The front wheel can be freely rotated and locked,
By adopting a tricycle system, not only straight lines but also curved lines and letters can be freely drawn and no skill is required. Therefore, since it is possible for anyone to easily work, it is possible to solve the problem of delay in restoration of road construction.

B. Beads can be sprinkled automatically using a box. Therefore, a worker for hand-spreading is not necessary, and it is possible to spread it evenly.

C. Since white line drawing and bead spreading can be done at the same time, one worker can do all the work. Therefore, the labor cost can be reduced.
