[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water spray tank structure for tire rollers, and more particularly to a technique for preventing clogging of a spray nozzle or a filter for spraying wheels.

[0002]

2. Description of the Related Art There is a self-propelled tire roller as a roller machine used for compacting a road or the like. The tire roller is provided with a plurality (about 3 to 6) of pneumatic tires (hereinafter, abbreviated as tires) at the front and rear of the lower part of the vehicle body. , The front and rear wheels are arranged in an odd-even number or an even-odd number. In general, the body of the tire roller is made of a thick steel plate, but the total weight becomes two to three times its own weight by adding ballast such as water or iron lumps. Each of the tire rollers is provided with a watering device for watering the wheels and watering the road surface to prevent the soil and pitch from adhering to the tires and to prevent the water content of the rolling contact road surface (roadbed, roadbed). Adjustments can be made. In addition, a small amount of water is sprayed on the tire from a spray nozzle having a fine spray hole, and a large amount of water is sprayed on a road surface from a spray nozzle having a relatively large slit. You. As the thousands of liters of water used for watering, river water or the like pumped up by a water suction pump is used from an economic viewpoint, and is stored in a watering tank provided inside the vehicle body and also serves as a part of ballast.

[0003]

However, such a conventional tire roller has the following disadvantages. In the above-described tire roller, the watering tank is generally formed by partitioning the inside of the vehicle body. Therefore, the inner wall of the watering tank is a relatively rust-resistant steel plate surface, and it is extremely difficult to completely perform surface treatment (such as rust-proof coating) from the structural point of view. Therefore, red water rust and scale are generated on the inner wall of the watering tank during repeated storage and discharge of river water and the like, and these are often flaked and mixed into the water. And these red rusts float in the water,
In some cases, a watering device for watering a wheel, particularly a filter, an injection hole of an injection nozzle, or the like is closed to impede a watering function.
In addition, fine dust, algae and the like are originally present in river water and the like, but these also become factors that block injection nozzles and the like like red rust and scale. In addition, since the road surface watering device does not have a filter and the slit of the watering nozzle is relatively large, the above-described problem does not occur.

[0004] The present invention has been made in view of such conventional problems, without greatly impairing the economy.
It is an object of the present invention to provide a water spray tank structure of a tire roller in which a filter or an injection nozzle of a wheel watering device is prevented from being blocked by red rust or the like.

[0005]

In order to solve this problem, the present invention is directed to a structure of a watering tank attached to a tire roller for watering the wheels and the road surface during traveling, and comprising a watering tank for watering the wheels. A watering tank is provided independently of a watering tank for road surface watering, and a watering tank structure for tire rollers, wherein the watering tank for wheel watering is formed using a rustproof material, is also proposed. In addition to the structure, the present invention proposes a watering tank structure for tire rollers, wherein the watering tank for watering the wheels is arranged on a center line passing through the center of gravity of the vehicle.

[0006]

[Function] A large-capacity watering tank for watering roads stores river water as before, but a relatively small-capacity watering tank for wheel watering is made of rust-proof material such as synthetic resin. Stores river water and tap water. Unlike the steel plate, red rust does not occur on the inner wall of the watering tank for watering wheels, so that the filter and the injection hole of the injection nozzle are prevented from being blocked. On the other hand, in the case where the watering tank for watering the wheels is arranged on the center line passing through the center of gravity of the vehicle, the center of gravity does not change even if the water in the watering tank decreases in accordance with the watering of the wheels.
Further, since the sprinkling tank is smaller in size than that for road surface sprinkling, it can be easily attached and detached and the inside can be washed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a side view of a tire roller according to an embodiment of the present invention, and FIG. 2 is a front view of the same. In these figures, reference numeral 1 denotes a vehicle body of a tire roller, and a lower part of a front wheel 3 consisting of four tires 2 is a steering wheel.
And a rear wheel 4 which is a driving wheel composed of five tires 2. One front wheel sprinkling pipe 6 is supported at the center of the front surface of the yoke 5 holding the front wheel 3. FIG.
As shown in FIG. 1 (enlarged view of part A), the front wheel sprinkling pipe 6 is provided with the same number (four) of injection nozzles 7 as the number of tires 2 on the front wheel 3 side. The atomized water is sprayed toward the mist. A hose 8 from the lower surface of the vehicle body 1 is connected to the center of the front wheel sprinkling pipe 6, and water is supplied through the hose 8.

On the other hand, one rear wheel watering pipe 9 and a pair of left and right road surface watering nozzles 10 are attached to the lower surface of the rear end of the vehicle body 1. As with the front wheel sprinkling pipe 6, the rear wheel sprinkling pipe 9 has the same number (5) as the number of tires 2 on the rear wheel 4 side.
Are mounted. In addition, the road surface watering nozzle 10 injects a small droplet of water in a fan shape in a substantially horizontal direction,
Sprinkle the road surface extensively. The front wheel sprinkling pipe 6 and the rear wheel sprinkling pipe 9 are both made of stainless steel.

FIG. 4 (cross section taken along line BB in FIG. 1) and FIG.
As shown in FIG. 1 (cross section taken along line CC in FIG. 1), the vehicle body 1 has a watering tank for watering a road surface (hereinafter referred to as a watering water for a road surface) in which a left and right upper portion partitioned by a partition 11 and a lower portion partitioned by a partition 12 are provided. 13). In the case of this embodiment, the road surface watering tank 13 has a capacity capable of storing about 4500 liters of water. At the center of the top end of the upper part of the vehicle body 1 (that is, on the center line passing through the center of gravity of the vehicle), a watering tank 14 made of synthetic resin for watering wheels (hereinafter referred to as a wheel watering tank) is housed. Since the wheel watering tank 14 can be easily attached and detached and the inside can be washed,
The injection nozzle 7 is always supplied with high quality water. In the case of this embodiment, the watering tank 14 for wheels is about 2
It has a capacity to store 00 liters of water. still,
In these figures, to avoid complications,
The power train, steering mechanism, and the like located at the center of the vehicle body 1 are not shown.

FIG. 6 is a perspective view showing the entire structure of the wheel sprinkler. In the figure, reference numeral 15 denotes an electric pump attached to the front surface of the lower part of the vehicle body 1, and sucks and discharges water from the wheel watering tank 14 via a hose 16.
The electric pump 15 is driven and controlled by a control device (not shown) provided in a driver's seat or the like, and pumps water through a hose 17 to a filter 18 installed behind the vehicle body 1.
After the water pumped by the electric pump 15 is filtered by the filter 18, the water is supplied to the front wheel watering pipe 6 and the rear wheel watering pipe 9 via the hoses 8 and 19. On the other hand, the road surface watering device is completely independent of the wheel watering device, and is composed of a relatively large water pump and pipes driven by an engine, but is not shown.

Next, the operation of this embodiment will be described. In the tire roller of the present embodiment, before compaction work is performed, fresh water is first drawn from a river or the like by a water pump of a road surface watering device and stored in the road surface watering tank 13. Tap water or river water is injected into the wheel watering tank 14 and stored. In the compacting operation, the road surface watering nozzle 10 performs watering of the road surface according to the condition of the road surface, and the injection nozzle 7 of the front wheel watering pipe 6 and the rear wheel watering pipe 9 transfers the wheel to the tires 2 of the front and rear wheels 3 and 4. Sprinkle water.
At this time, by operating the above-described control device, the watering of the wheels can be performed continuously or intermittently.

In the tire roller of the present embodiment, as described above, the wheel watering tank 14 is made of a synthetic resin. Therefore, generation of red rust and scale is completely prevented on the inner wall of the wheel watering tank 14, and when clean water such as tap water is stored, dust and algae do not exist in the water. As a result, even after long-term use, clogging of the filter 18 and the injection nozzle 7 with foreign substances is eliminated, and the maintenance interval can be dramatically increased. In addition, even when river water or the like is used, red rust and scale no longer exist, and by desorbing and cleaning the inside appropriately, high-quality water can always be supplied to the injection nozzle 7, while the size of the filter 18 itself is reduced. Also, it could be made smaller than the conventional one.

On the other hand, in the tire roller, the driver's seat is located on either the left or right side of the upper surface of the vehicle body 1, but the weight is balanced by mounting a heavy object such as a battery on the opposite side. Therefore, even in a state where water does not enter the two watering tanks 13 and 14, the horizontal direction is balanced, and the center of gravity is in the center line shape of the vehicle body 1. In this embodiment, since the wheel sprinkling tank 14 is arranged on the center line passing through the center of gravity of the vehicle body 1, the position of the center of gravity does not move due to the change in the internal capacity in the process of sprinkling the wheels, and the work is stable. Can be done.

Although specific embodiments have been described above, embodiments of the present invention are not limited to these embodiments.
For example, in the above-described embodiment, the material of the watering tank 14 for wheels is made of synthetic resin. However, it may be made of FRP or a normal steel plate or a stainless steel plate whose inner surface is subjected to rust prevention treatment. Also, when the watering tank 14 for wheels is mounted on a center line passing through the center of gravity of the vehicle, the position is not limited to the tip of the vehicle body 1.

[0015]

As described above, according to the tire roller watering tank structure of the present invention, the watering tank for wheel watering is
Since it is made independent from the watering tank for road surface watering and formed using a rust-preventive material, red rust does not occur in the watering tank, preventing the filter and the injection hole of the injection nozzle from being blocked. It works. Further, in the case where the watering tank is arranged on the center line passing through the center of gravity of the vehicle, the position of the center of gravity does not move due to the change in the internal capacity, and an effect that stable work can be performed.
