Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an iron plate with a built-in water sprinkler for cleaning tires of a dump truck or the like that carries excavated earth and sand in root excavation work.

[0002]

2. Description of the Related Art Conventionally, excavated earth and sand are carried out of a construction area by a dump truck to a residual soil treatment plant. At that time, mud adheres to the tire of the dump truck, and if it goes out of the construction area as it is, it will pollute the general road. In addition, dust and sand dust will fly around, causing complaints from surrounding residents due to dust pollution. Therefore, normally, for example, a guard man or the like cleans the tire of the dump truck near the exit.

As a method of cleaning the tire, it is known to clean the tire with a tool such as a high washer.

[0004]

However, in the method of manually cleaning the tire by the guard man or the like, it takes time and the cost is increased. Also,
There is also a problem that the person who is to be washed is also soiled by the splash of mud or the like. The iron plate with a built-in sprinkler according to the present invention has been proposed to solve such a problem.

[0005]

The gist of the iron plate with a built-in sprinkler according to the present invention for solving the above-mentioned problems is to provide the washing object with the washing water at least at the portion where the object to be washed passes. Is to be equipped with a sprinkler for spraying and cleaning

The sprinkler is provided so as to cover at least the entire circumference of the automobile tire, which is the object to be washed, and detects that the object to be washed is present on the laid iron plate. And a control device that is connected to the detection device and that controls the sprinkler device so that the sprinkler device is driven for a certain period of time.

According to the iron plate with a built-in water sprinkler according to the present invention, the mud-adhering tire is automatically cleaned to remove the mud, and the entire circumference of the tire is cleaned.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Next, a spreader built-in iron plate according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3, the sprinkler built-in iron plate 1 has a thickness of 22 mm and a size of 1.5 mm, for example.
Spread 4 m × 6m existing ones.

A water sprinkler 3 is provided on the spread iron plate 2. The arrangement of the water sprinkling device 3 is provided at least in a portion through which the tire, which is an object to be cleaned, passes. Also,
It is provided so as to cover the range of the entire circumference of the automobile tire that is the cleaning target. In this embodiment, the spread iron plate 2 is divided into a front half portion and a rear half portion, and the water sprinklers 3 are arranged corresponding to the positions of the tires in each.

As shown in FIGS. 4 to 5, in the water sprinkling device 3, a water sprinkling pipe 3c is supported by a base 4 in the recess 2a of the spread iron plate 2. Sprinkler pipe 3 shown in FIG.
Reference character a is a vertical water spraying pipe for vertically spraying, and water spraying pipe 3b shown in FIG. 5B is an inclined water spraying pipe having an inclined upper surface and spraying in a slanting direction to wash the side surface of the tire.

The water spray pipe 3c is provided with a plurality of thin injection pipes 3d and 3e. This injection pipe 3d,
A nozzle for watering is provided at the nozzle of 3e.

As shown in FIGS. 3 (A) and 3 (B), the arrangement of the water spray pipe 3a and the water spray pipe 3b is such that the water spray pipe 3a is arranged in the center and the water spray pipes 3b are arranged on both sides thereof. It
This is because the tire 6a of the truck 6 that transports the residual soil is a double tire, so that the central portion and the side surface of the double tire are washed at the same time.

Below the water spray pipes 3a and 3b, as shown in FIGS. 2 and 5, a horizontal water supply pipe 5 is provided. This water supply pipe 5 is connected to an automatic washing machine 7 via a washing hose 5a. Further, the automatic washing machine 7 has
An optical sensor 8, which is a detection means disposed at an appropriate position, is electrically connected so as to detect the position of the tire 6a indexed from the position of the truck 6 on the laid iron plate 2.

The automatic cleaning device 7 includes the optical sensor 8
When the presence of the truck 6 is detected and the truck is turned on, the washing water is controlled to be sprayed from the sprinkling pipes 3a and 3b for a certain period of time by the timer setting. The detecting means is not limited to an optical sensor, and may be a known detecting means such as a mechanical sensor.

A method of using the iron plate 1 with a built-in sprinkler of the present invention thus formed will be described. First, the truck 6 loaded with the residual soil rides on the front half of the iron plate 1 with a built-in sprinkler according to the present invention (state shown in FIGS. 1 and 2). Stop once at this position. Then, the optical sensor 8
Detects the presence of the truck 6, an electric signal thereof is transmitted to the automatic washing machine 7, and the control unit starts the washing start.

The automatic washing machine 7 (iron plate 1 with a built-in sprinkler)
The cleaning action of the automatic washing machine that is in charge of the first half of the above) is activated, and the washing water is supplied from the washing hose 5a to the sprinklers 3 through the water supply pipe 5 and sprayed. In this cleaning action, as shown in FIG. 3B, the lower half of the tire 6a for the front wheels and the tire 6a for the rear wheels of the truck 6 is cleaned.

When the washing water is jetted for a certain period of time, the jetting action is stopped by the automatic washing machine 7. After that, the truck 6 advances on the spread iron plate 2, moves to the latter half of the spreader built-in spread iron plate 1, and stops (state shown in FIGS. 6 and 7).

By moving the truck 6 to the latter half,
In each tire 6a, the upper half, which is an unwashed portion in the front half of the spread iron plate 2, is changed to the lower half in the rear half. Then, the presence of the truck 6 is detected by the optical sensor 8, and the tire 6 is washed in the same manner as the cleaning operation in the first half.
The lower half of a is washed. In this way, the front half and the rear half of the laid iron plate 2 are washed over the entire circumference of the tire 6a.

Then, after the washing water is sprayed for a certain period of time, the truck 6 further advances and comes out of the construction area from the iron plate 1 with a built-in sprinkler.

In the above embodiment, the truck 6 is temporarily stopped and washed on the iron plate 1 with a built-in sprinkler, and the sprinkler 3 is used for the front and rear tires 6 of the truck.
It is arranged corresponding to the position of a. Not limited to this, the sprinkler 3 is arranged at appropriate intervals within the range where the tire 6a passes, and the truck 6 does not stop,
While slowly moving forward, wash water is sprayed to the tire 6
You may make it wash a.

In addition, in the sprinkler 3, the injection pipes 3d,
It is preferable that the nozzle of the nozzle 3e sprays the cleaning water at a wide angle so that not only the tire 6a but also the mudguard cover of the truck 6 and other vehicle body parts are simultaneously cleaned.

The iron plate 1 with a built-in water sprinkler is preferably provided near the exit not only at the construction site but also at the remaining soil treatment site so that dust will not fly.

[0023]

As described above, the spreader iron plate with a built-in sprinkler according to the present invention is a water sprayer for spraying cleaning water onto the cleaning target object at least in a portion of the flooring iron plate where the cleaning target object passes. Since the device is provided, the cleaning action is efficiently performed, and the excellent effect that the cleaning time is shortened is exhibited.

Since the sprinkler is provided so as to cover at least the entire circumference of the automobile tire which is the object to be washed, it is possible to cleanly wash the mud and the like adhering to the tire. Further, since the detection means for detecting the presence of the object to be cleaned on the laid iron plate and the control device connected to the detection means for controlling the sprinkler device to be driven at a fixed time are provided, automatic cleaning is performed. Is possible.
