Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a slime agent spraying machine that spreads a slime agent such as coal tar in a strip along the roadside near the shoulder of the road.

``Prior art'' The area near the shoulder of the road is used to create a separation from the sidewalk, to prevent wheels from falling off the shoulder, and to prevent rainwater from flowing to the side of the road. Therefore, blocks of small height and width are laid in a strip shape.

This block is usually made of concrete and is buried in a predetermined location on the road surface, but there are also blocks made of a bituminous mixture such as asphalt.

In particular, as a preliminary step to laying bituminous mixtures such as asphalt as blocks, a slime agent as an adhesive is spread on the road surface in a strip along the roadside near the shoulder. ing.

``Problem that the invention aims to solve'' This mucus agent is generally applied in a strip with a designated brush, but it is extremely time-consuming because it is done at long intervals along the road surface. There were problems such as inefficiency, high labor costs, uneconomical costs, inability to apply accurately in strips, and unevenness.

In addition, the above-mentioned mucilage is an emulsion whose main component is coal tar, etc., and although it is a mucus, it flows easily, so after application, it flows out to the center of the road surface, staining it, damaging vehicle tires, etc. If the mixture flows out, the amount of coating will be relatively small, so there is a disadvantage that when the mixture is laid as a block, the reliability of fixation is lost.

The present invention is a slime spraying machine devised to eliminate the above-mentioned conventional drawbacks and inconveniences, and its purpose is to provide a slime sprayer that is easy to construct, has a good-looking finish, and can spray slime reliably. do.

"Means for Solving the Problem" Hereinafter, the configuration of the present invention will be described based on drawings showing embodiments of the present invention.

The slime agent spraying machine of the present invention sprays a slime agent such as coal tar in a strip along the roadside near the shoulder of the road. In addition to a nozzle body 10 projecting from the nozzle body 10, guide pieces 11 and 12 with lower ends substantially in contact with the road surface are suspended from the inside and rear side of the nozzle body 10.

The main body 1 is capable of at least forward movement, and therefore the guide piece 12 located on the rear side of the nozzle body 10
This means the rear side with respect to the forward direction of the main body 1.

"Operation" With the above-mentioned configuration, if the main body 1 of the slime spraying machine of the present invention is run along one side edge of the road with its nozzle body 10 positioned at a predetermined side edge of the road. , the mucus agent ejected from the nozzle body 10 can be reliably sprayed at a predetermined position on the road surface,
Inner guide piece 11 that moves while tracing the road surface
prevents the sprayed mucilage from flowing toward the center of the road surface, and the rear guide piece 12, which moves while tracing the road surface, evenly applies the sprayed mucus to the road surface. You will be able to do so.

That is, the rear guide piece 12 functions as a brush for reapplying the sprayed mucus agent.

In addition, when the main body 1 is run, the nozzle body 10
The nozzle body 10 is disposed at the side end of the main body 1 so that the direction in which the mucus agent is ejected from the body can be visually confirmed when viewed from the side.

"Embodiment" The main body 1 has a storage tank 2 for a mucus agent and a tank 3 for storing water, and the mucus agent tank 2 communicates with the nozzle body 10 via a connecting pipe 13.
The mucus agent is pumped by a pump 4 disposed in the middle of the connecting pipe 13 and is ejected from the nozzle body 10.

The nozzle body 10 is arranged at the lower end of one side of the main body 1, and is movable up and down in this position, so that the distance between the jet opening end and the road surface can be adjusted. This controls the ejection range of the mucus agent.

Further, the guide pieces 11 and 12 are made of flexible rubber material, etc., but especially the rear guide piece 12
A brush-shaped one is preferable because it functions to level out the ejected mucus agent.

The main body 1 has front wheels 6 and rear wheels 8, and is capable of running smoothly.As a means of running, it is conceivable to use a predetermined power, but it is also possible to move slowly with delicate control. It is preferable to use human power to move the robot forward, and therefore, a handle 9 for pushing by hand is provided at the rear end of the main body 1.

It is desirable that the wheels have a so-called caster structure that allows them to freely turn around an axis at a predetermined angle to the wheel axis so that they can smoothly turn a certain curve. If all of them have this structure, the caster shaft will rotate too much and become unstable, making it difficult to control.

Therefore, in the illustrated embodiment, the pair of front wheels 6 are rotatably assembled to the main body 1 via the axle 7, and
The rear wheel 8 has a caster structure and is attached to the center of the rear end of the main body 1.

As mentioned above, the nozzle body 10 is arranged at the side end of the main body 1 so that the state of the mucus agent ejected from the nozzle body 10 can be visually confirmed. It is designed to prevent it from being stepped on by the rear wheels 8 of the main body 1 or by the operator.

The pump 4 described above is driven by a power source 5 built into the main body 1.

Next, in the illustrated embodiment, the main body 1 is
Storage tank 2 for storing mucus agent and tank 3 for storing water
and.

Since the mucilage agent is an emulsion whose main component is coal tar, etc., after use, the nozzle body 10 and the connecting pipe 1 must be
There is a problem that the space between the two and three is easily clogged. Therefore, in order to clean the inside of the connecting pipe 13 after use, water in the tank 3 is pumped between the nozzle body 10 and the connecting pipe 13.

FIG. 4 shows a specific means for this purpose, in which the end of the connecting pipe 13 connected to the pump 4 is
A mucus agent communication pipe 14 communicating with the mucus agent storage tank 2
and a water communication pipe 15 that communicates with the water storage tank 3, and a cock 16 is provided in the mucus agent communication tube 14 and the water communication tube 15, respectively. Only the socket 16 of the communication pipe 14 is opened, and when water is to be spouted, only the socket 16 of the water communication pipe 15 is opened.

"Effects" The present invention has the structure and functions as explained above.

Therefore, when spreading a slime agent such as coal tar in a strip along the roadside shoulder, it is possible to spread it evenly and reliably without spilling out, and work efficiency is improved because it is not done manually. It is economical because the number of workers can be kept to a minimum, and the aesthetic appearance is ensured because the mucus agent does not flow out onto the road surface. It has many excellent effects, such as making it possible to securely and easily lay a block formed by compacting the mixture.
