Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water sprinkler tank structure for tire rollers, and more particularly to a technique for preventing clogging of a spray nozzle of a wheel sprinkler or a filter.

[0002]

[Prior Art]

 As a roller machine used for compacting roads, there is a self-propelled tire roller. The tire rollers are equipped with a plurality of air tires (about 3 to 6 tires) (hereinafter abbreviated as tires) at the front and rear of the lower part of the vehicle body so that the rear wheels can roll the portion left untouched by the front wheels. In addition, the front and rear wheels are arranged in odd-even or even-odd. Generally, the vehicle body of the tire roller is made of a thick steel plate, but the total weight becomes 2 to 3 times its own weight by adding ballast such as water or iron ingot. The tire rollers are equipped with sprinklers for wheel sprinkling and road sprinkling, respectively, to prevent soil and pitch from adhering to the tires, and to prevent water content on the road surface (roadbed, roadbed). It can be adjusted. A small amount of water is sprayed on the tire from a spray nozzle with fine spray holes, and a large amount of water is sprayed on the road from a spray nozzle with a relatively large slit. Is sprinkled on. From the economical point of view, river water, etc. pumped by a suction / dispersion pump is used as the water of several thousand liters used for watering, and it is also stored in a watering tank inside the car body and also serves as part of the ballast.

[0003]

[Problems to be solved by the device]

 However, such a conventional tire roller has the following problems. In the tire roller described above, the water sprinkling tank is generally formed by partitioning the inside of the vehicle body. Therefore, the inner wall of the water sprinkler tank is a steel plate surface that is relatively susceptible to rust, and it was extremely difficult to completely perform surface treatment (corrosion preventive coating, etc.) from the structural viewpoint. Therefore, during repeated storage and release of river water, red rust and scale were generated on the inner wall of the water sprinkling tank, and these were often removed and mixed into the water. These red rusts may float in the water and block the sprinklers for wheel sprinkling, especially the filters and the injection holes of the injection nozzles, thus impairing the sprinkling function. In addition, minute dust, algae, etc. are originally present in river water, etc., but these have also been factors that have clogged the injection nozzles, etc., like red rust and scales. The sprinkler of the road surface sprinkler does not have a filter and the slit of the sprinkler nozzle is relatively large, so that the above-mentioned problems do not occur.

The present invention has been made in view of such conventional problems, and it is a tire roller that prevents the filter of the wheel sprinkler or the injection nozzle from being blocked by red rust or the like without significantly impairing the economical efficiency. It is an object of the present invention to provide a sprinkler tank structure.

[0005]

[Means for Solving the Problems]

 Therefore, in order to solve this problem, the present invention has a structure of a water sprinkler tank attached to a tire roller that sprinkles wheels and roads while driving, in which a sprinkler tank for sprinkling wheels is used. In addition to this structure, we proposed a tire roller sprinkler tank structure characterized in that the sprinkler tank for sprinkling the wheels was formed using a rust preventive material. This is a proposal for a water tank tank structure for tire rollers, in which a water tank for watering is arranged on the center line passing through the center of gravity of the vehicle.

[0006]

[Action]

 Large-capacity road surface sprinkler tanks store river water, etc. as before, but comparatively small-capacity wheel sprinkler tanks are made of synthetic resin and other rust-preventive materials. And tap water. Unlike steel plates, no red rust occurs on the inner wall of the water spray tank for wheel sprinkling, which prevents the filters and injection nozzles from being closed. On the other hand, if the water sprinkling tank for wheel sprinkling is placed on the center line that passes through the center of gravity of the vehicle, the center of gravity does not change even if the water in the sprinkling tank decreases in response to wheel sprinkling. Further, since this water sprinkling tank is smaller than the water sprinkling tank for road surface water sprinkling, the water sprinkling tank can be easily attached and detached and the inside can be cleaned.

【Example】

 Hereinafter, embodiments of the present invention will be described 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 thereof. In these figures, reference numeral 1 is a vehicle body of tire rollers, and a front wheel 3 which is a steered wheel composed of four tires 2 and a rear wheel 4 which is a driven wheel composed of five tires 2 are attached to the lower part thereof. ing. A front wheel sprinkling pipe 6 is supported at the center of the front surface of the yoke 5 that holds the front wheel 3. As shown in FIG. 3 (enlarged view of portion A in FIG. 1), the front wheel sprinkler pipe 6 is equipped with the injection nozzles 7 for the number of tires 2 on the front wheel 3 side (4 tires). The atomized water is jetted toward the tread surface of the. 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 this hose 8.

On the other hand, one rear wheel water sprinkling pipe 9 and a pair of left and right road surface water sprinkling nozzles 10 are attached to the lower surface of the rear end of the vehicle body 1. Similar to the front wheel sprinkling pipe 6, the rear wheel sprinkling pipe 9 is equipped with injection nozzles 7 for the number of the tires 2 on the rear wheel 4 side (five). Further, the road surface water spray nozzle 10 sprays water in the form of fine droplets in a fan shape in a substantially horizontal direction, and sprays water on the road surface in a wide range. The front wheel sprinkling pipe 6 and the rear wheel sprinkling pipe 9 are both made of stainless steel.

As shown in FIG. 4 (section B-B in FIG. 1) and FIG. 5 (section C-C in FIG. 1), the vehicle body 1 is divided into upper and left parts by partition walls 11 and partition walls 12. The partitioned lower part is a watering tank for road surface watering (hereinafter referred to as road surface watering tank) 13. In the case of the present embodiment, the road surface sprinkling tank 13 has a capacity capable of storing approximately 4500 liters of water. At the center of the tip of the upper part of the vehicle body 1 (that is, on the center line passing through the center of gravity of the vehicle body), a water sprinkling tank 14 for water sprinkling wheels made of synthetic resin (hereinafter referred to as a water sprinkling tank for wheels) is housed. The sprinkling tank 14 for wheels can be easily attached and detached and the inside of the sprinkling tank 14 can be cleaned. Therefore, good quality water is always supplied to the jet nozzle 7. In the case of this embodiment, the wheel sprinkling tank 14 has a capacity capable of storing approximately 200 liters of water. In addition, in order to avoid complication, the power train, the steering mechanism, and the like located in the center of the vehicle body 1 are not shown in these drawings.

FIG. 6 is a perspective view showing the entire structure of the wheel sprinkler. In the figure, reference numeral 15 is an electric pump attached to the front surface of the lower portion of the vehicle body 1, which sucks and discharges water from the wheel water spray tank 14 via the hose 16. The electric pump 15 is drive-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. The water pumped by the electric pump 15 is filtered by the filter 18, and then supplied to the front wheel sprinkling pipe 6 and the rear wheel sprinkling pipe 9 via the hoses 8 and 19. On the other hand, the road surface sprinkler is completely independent of the wheel sprinkler, and consists of a relatively large water pump and pipes driven by the engine, but not shown.

Next, the operation of this embodiment will be described. In the tire roller of the present embodiment, before performing the compacting work, first, fresh water is pumped up from a river or the like by a water pump of a road surface water spraying device and stored in a road surface watering tank 13. In addition, tap water, river water, or the like is injected into the wheel sprinkling tank 14 for storage. In the compaction work, the road surface water spray nozzle 10 sprays the road surface water according to the condition of the road surface, and the front nozzles 6 and the rear wheel water spray pipes 9 spray nozzles 7 to the front and rear wheels 3 and 4 tires 2. Water the wheels. At this time, wheel sprinkling can be performed continuously or intermittently by operating the control device described above.

In the tire roller of this embodiment, the wheel sprinkling tank 14 is made of synthetic resin as described above. Therefore, the 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 are not present in the water. As a result, the filter 18 and the injection nozzle 7 are not clogged with foreign matter even after long-term use, and the maintenance interval can be dramatically increased. In addition, even when river water is used, red rust and scale are eliminated, and by properly removing and cleaning the inside, it is possible to always supply good quality water to the injection nozzle 7, while the filter 18 itself The size 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 if there is no water in the sprinkler tanks 13 and 14, the water is balanced in the left-right direction, and the center of gravity is on the center line of the vehicle body 1. Further, in the present embodiment, since the vehicle water sprinkling tank 14 is arranged on the center line passing through the center of gravity of the vehicle body 1, there is no possibility that the position of the center of gravity will move due to the change of the internal volume during the process of water sprinkling the wheels, which is stable. You can work.

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