Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is for asphalt pavement compaction work that evenly compacts the asphalt pavement surface. Regarding machines.

0002

[Conventional technology]

Generally, the final finish of asphalt pavement is compacted flat using compaction machines. Rolling machines now have rubber tire rollers and steel rolling wheels. Road rollers are generally known.

0003

[Problem that the idea aims to solve]

As mentioned above, the asphalt pavement surface is compacted flat by a compaction machine. However, especially for tire rollers whose rolling wheels are made of rubber, If the tires are cold, asphalt may stick to the tire side during compaction work, causing damage. There was a problem that a good finished surface could not be obtained.

0004 In this case, for example, by pouring boiling water heated to around 80 degrees Celsius onto the rolling contact surface of the tire. Although it has been found through experiments that it is possible to prevent asphalt from adhering, there are many Large-scale heating equipment is required to maintain and manage the amount of hot water used in rolling mills. This is undesirable as it may lead to larger industrial machines.

[0005] Therefore, with this idea, spraying light oil on the rolling surface will prevent asphalt from adhering. This was done with a focus on the fact that it can be prevented, and it greatly reduces the amount of light oil used This method can also be easily applied to conventional tire rollers and road rollers. Ru.

[0006]

[Means to solve the problem]

In order to achieve the above object, this invention has a machine body equipped with rolling wheels at the front and rear. In contrast, the water pumped out from the water tank is replaced by the water pumped out from the diesel tank. A spraying device is installed to mix the mixed light oil and spray it from the first and second spraying nozzles. Place the first spray nozzle on the front rolling wheel and the second spray nozzle on the rear rolling wheel. Distribute it on the rolling surface of each rolling wheel.

[0007]

[Effect]

According to this asphalt paving compaction machine, light oil is mixed with water and used. Therefore, the amount of oil used is small, and it can be transferred by spraying the mixed oil from the spray nozzle. Asphalt does not adhere to the pressure ring. Also, set the spraying device on the aircraft. It can be easily implemented on conventional tire rollers and road rollers. .

【Example】

Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 and 2. .

[0009] In the figure, 1 indicates the body of the tire roller 3. There are rubber rollers at the front and rear of fuselage 1. Pressure wheels 5 and 7 are arranged, and the front pressure wheel 5 is moved in the left and right direction by the steering wheel 9. It has a steering wheel that can change direction. The rear rolling wheel 7 receives power from the engine 11. It serves as a driving wheel to which power is transmitted via a transmission 13 and a transmission chain 15.

0010 Furthermore, a spraying device 17 is mounted on the aircraft body 1 as shown in FIG. The spraying device 17 includes a water tank 19, a light oil tank 21, and first and second spray nozzles 2. 3 and 25, and the water tank 19 contains water and is fixed to the abdomen of the aircraft 1. It also connects with the first and second spray nozzles 23 and 25 via the water pump 27. It continues. The water pump 27 is connected to the engine by a transmission means such as a belt 29. Rotational power is given from engine 11, and it is always on at the same time as engine 11 starts. It will be destroyed. As a result, the water in the water tank 19 is distributed to the first and second spray nozzles 23 and 25. It will be sent towards. In addition, when not in use, the pressure adjustment valve 31 The water then returns to the water tank 19.

[0011] The light oil tank 21 contains cheap and easily available light oil, and is located behind the driver's seat 33. It is fixedly supported by the fuselage 1. The light oil tank 21 has a manual on-off valve 35 and an oil pump. The water pump 37 is connected and communicated with the suction side of the water pump 27 via the solenoid valve 39. The oil is injected into the suction side in a foamy state. oil pump 3 7 becomes activated when a manual switch (not shown) is turned on, and the electromagnetic The valve 39 is also controlled to open at the same time, and this solenoid valve 39 is opened when the oil pump 37 is turned on. When it becomes closed, it can be switched to close.

0012 The first and second spraying nozzles 23 and 25 spray mixed oil by opening the on-off valve 41. The first spraying nozzle functions to spray toward the rolling surfaces 5a, 7a of the rolling wheels 5, 7. The nozzle 23 is fixedly supported on the machine body 1 above the front rolling wheel 5, and the nozzle 23a is The number corresponds to the number of rolling wheels 5, and in this embodiment, four are provided.

[0013] The second spray nozzle 25 is fixedly supported on the machine body 1 above the rear rolling wheel 7. The number of nozzles 25a corresponds to the number of rolling wheels 7, and in this embodiment, five nozzles are provided. There is.

[0014] According to the asphalt pavement compaction machine configured in this way, it is possible to drive into the asphalt pavement and compact the surface. At this time, open the on-off valve 41. After that, by activating the oil pump 37, the light oil is pumped out from the light oil tank 21. The light oil is injected in a foamy state into the water sent out from the water tank 19. From the first and second spray nozzles 23, 25, the front and rear rolling wheels 5 are mixed together. , 7 toward the rolling surfaces 5a, 7a. As a result, the rolling wheel 5, No more asphalt adhesion to 7 and a clean finished surface can be obtained. Also, light oil The amount used will also be reduced. From these first and second spray nozzles 23 and 25 Spraying continues until each rolling wheel 4, 7 warms up and no asphalt adheres to it. .

[0015] In this example, tire rollers were explained, but road rollers also have Similar effects can be obtained even if

[0016]

[Effect of the idea]

As explained above, according to the compaction work machine of this invention, conventional tire rollers and This can be easily implemented on road rollers. Also, by mixing light oil with water, To reliably prevent asphalt from adhering to rolling wheels by a simple method of spraying At the same time, the amount of light oil used can be reduced.
