Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cleaning tool for a road drain.

[0002]

2. Description of the Related Art The applicant of the present invention has previously proposed a cleaning tool for a circular waterway suitable for removing soil and the like E deposited on a circular waterway D1a as shown in FIG.
No.). The circular waterway D1a has a circular cross-sectional shape in the width direction, and is buried in the road as an in-road waterway on a highway or the like. A tapered gap D is formed at an upper portion, for example, with a width of 5 to 6 cm, and the opening area increases as going upward.
11 Therefore, water on the road surface D in rainy weather or the like flows into the circular waterway D1a via the gap D11, and the square D12
Is discharged to the outside. However, soil and the like are mixed in the water, so that these E accumulate in the circular water channel D1a. However, since the gap D11 is narrow, cleaning the circular waterway D1a has been a troublesome operation by hand. Therefore, the above-mentioned "cleaning device for circular waterways" has solved this troublesome work.

[0003] A high-pressure water pipe having a large number of high-pressure water injection ports opened at the lower end toward the inner wall surface of the circular water passage D1a and a suction pipe having a substantially semicircular trainer-shaped suction port at the lower end are rotatable. To be configured. At the time of use, first, both pipes are rotated so that the longitudinal direction of the lower ends of both pipes is parallel to the gap D11, and when they become parallel, both lower ends are inserted into the circular water channel D1a. After insertion, rotate both tubes 90 degrees. In this case, the surface direction of the trainer becomes the lateral direction of the circular water channel D1a. Then, high-pressure water is injected from the high-pressure water injection port to scrape the soil E or the like accumulated in the circular water passage D1a, and the water advances while sucking and removing the soil E and the like mudified by the scraping from the suction port. When the cleaning is completed, both pipes are again rotated by 90 degrees and pulled out from the gap D11.

[0004]

According to the above configuration, the circular water channel D1a can be cleaned by one worker, which greatly contributes to labor saving. However, there are the following problems. (1) The suction port has a substantially semicircular trainer shape. If the outer diameter of the trainer is made to substantially match the inner diameter of the circular channel D1a, the trainer cannot move up and down in the circular channel D1a. That is, when the soil E is hard or the sediment E is accumulated in a large amount, it becomes difficult even to insert the trainer into the circular waterway D1a. In addition, the trainer cannot advance unless all the soil E or the like on the front surface of the trainer is sucked, and therefore, the working speed is reduced. Conversely, if the outer diameter of the trainer is made smaller than the inner diameter of the circular water passage D1a, the high-pressure jet water dislodges the soil E etc., which includes the sediment E on the outer periphery of the trainer. It may flow out behind the trainer before being sucked. Therefore, the suction efficiency is not good. (2) Pavement material, snow melting material, and the like are often mixed into the circular water channel D1a. When this happens, the earth and sand E solidifies,
Further, it is fixed to the circular water channel D1a and cannot be scraped off with only high-pressure jet water or a trainer.

The present invention has been made in view of the above-mentioned problems of the prior art,
An object of the present invention is to provide a road drain cleaning tool that can efficiently clean a road drain at a high speed.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, a first embodiment of a road drain cleaning tool according to the present invention is provided.
Is a suction pipe 1 having a blade 1b and a suction port 1c at the lower end.
And a high-pressure water pipe 2 having a high-pressure water injection port 2b at the lower end. Both lower ends are inserted into the road drainage groove D1 and accumulate on the front surface of the blade 1b while jetting high-pressure water from the high-pressure water injection port 2b. In a road drain cleaning tool for sucking and removing mud from suction port 1c, (a) blade 1b is
When installed in the road drainage groove D1, the blade 1b has a front shape that can move up and down while rotating to at least half the height of the road drainage groove D1, and (b) the high-pressure water injection port 2b And pressurized water is sprayed toward the front of the blade 1b.

According to the first configuration, the following operation and effect can be obtained. The blade 1b can move up and down in the road drainage groove D1 to at least half the height of the road drainage groove D1. Therefore, the blade 1b can be inserted into the road drainage groove D1 without any resistance and can be cleaned while the hardness or the amount of sediment E does not exceed the vertical movement height. Therefore, the cleaning speed increases. Further, since the high-pressure water injection port 2b injects the pressure water toward the front of the blade 1b, the soil E or the like to be scraped is limited to the soil E or the like facing the front surface of the blade 1b. Therefore, it is possible to prevent the muddy water from flowing backward to the blade 1b. That is, muddy water suction efficiency is improved. This also means that the amount of high-pressure water may be small. Therefore, muddy water can be prevented from blowing up on the road surface D during cleaning. That is, icing on the road surface can be prevented, and thus cleaning in winter is also possible. The road drain D1 is a circular waterway D1.
It is not limited to a. Further, the wording “while rotating” in the first configuration is not limited to “it is essential that the blade 1b rotates”, and “like in the left-right direction” like the blade 1b can move up and down. There is room for this. " However, the blade 1b in the first configuration may be rotatable.

Second, the blade 1b and the suction port 1c are provided at the lower end.
And a high-pressure water pipe 2 having a high-pressure water injection port 2b at its lower end. The lower end is inserted into the road drainage groove D1 to eject high-pressure water from the high-pressure water injection port 2b, while the blade 1b (A) The high-pressure water injection port 2b injects pressurized water toward the front of the blade 1b.
(b) The suction pipe 1 and the high-pressure water pipe 2 are arranged side by side in the front-rear direction, and (c) the suction pipe 1 is horizontally rotatable.

According to the second configuration, the following operation and effect can be obtained. Since the high-pressure water injection port 2b only injects pressure water toward the front of the blade 1b, a mechanism for rotating the high-pressure water pipe 2 as in the related art can be omitted. Can be simplified. On the other hand, when the suction tube 1 is rotated horizontally, the blade 1
b also rotates horizontally. Moreover, the suction pipe 1 and the high-pressure water pipe 2 are arranged side by side in the front-rear direction. Therefore, even if the road drainage groove D1 is a circular waterway D1a, it can be cleaned. That is, first, blade 1
By making b parallel to the gap D11, the lower ends of the suction pipe 1 and the high-pressure water pipe 2 can be inserted into the circular water path D1a. Then, the lower end of the blade 1b or the high-pressure water pipe 2 is inserted into the circular water path D1a through the gap D11, and then the suction pipe 1 is rotated by 90 degrees so that the blade 1b can be laterally moved by the circular water path D1a. Cleaning can be started.

Third, a blade 1b and a suction port 1c are provided at the lower end.
And a high-pressure water pipe 2 having a high-pressure water injection port 2b at its lower end. The lower end is inserted into the road drainage groove D1 to eject high-pressure water from the high-pressure water injection port 2b, while the blade 1b A cleaning device for a road drainage ditch for sucking and removing muddy water accumulated on the front of the blade through a suction port 1c, the lower end of which is a blade 1
The rake 3 is characterized in that it has a rake 3 located in front of the lower end of b.

According to the third configuration, the following operation and effect can be obtained. Since the rake 3 is provided in front of the blade 1b, the soil and the like E solidified and deposited in the road drain ditch D1 can be excavated and scraped by the rake 3. The excavated soil E is muddy by high-pressure water. Therefore, the cleaning speed increases. In addition, high pressure water is used as in the prior art, such as earth and sand.
Instead of scraping, the main thing is to make it muddy. For this reason, high pressure water may be used at low pressure and in a small amount. Therefore, cleaning in winter is also possible.

Fourth, in the third configuration, the rake 3
The rake 3 is connected to the traveling vehicle B via a universal joint 5 that supports the rake 3 so as to float in the width direction of the road drain groove D1.

According to the fourth configuration, the following operation and effect can be obtained. Rake 3 is rigid. When such a rake 3 is directly connected to the traveling vehicle B, the rake 3 interferes with the road drain ditch D1 (for example, the gap D11 of the circular water channel D1a) due to right and left vibrations of the traveling vehicle B during traveling, and the road drain ditch D1 is easily formed. It will be destroyed. However, in the fourth configuration, the rake 3 and the traveling vehicle B are connected by a universal joint 5 that can float in the width direction of the road drainage groove D1. For this reason, the destruction of the road drain D1 can be prevented. By pulling, the driving of the traveling vehicle B becomes easy, and the cleaning speed is dramatically increased.

Fifth, in the fourth configuration, the rake 3 is provided so as to be able to move up and down with respect to the traveling vehicle B.

According to the fifth configuration, the following operation and effect occur, and are superimposed on the operation and effect of the fourth configuration. As described above, the rake 3 is rigid. Therefore, supporting such a rake 3 to the traveling vehicle B so as to be able to move up and down freely is as follows.
It makes sense in terms of strength. That is, according to the fifth configuration, not only can the cleaning tool of the road drainage ditch be raised and lowered, but also the traction force of the traveling vehicle B, that is, the excavation force of the rake 3 can be effectively extracted, and high-speed cleaning can be performed.

Sixth, in the above fourth configuration, (a) the traveling vehicle B includes a lower traveling body B2, an upper revolving body B3 rotatably provided on the lower traveling body B2, and an upper revolving body B3. This is a self-propelled vehicle having a refracting arm B1 provided to be able to move up and down, and (b) a rake 3 is provided at the tip of the refracting arm B1.

According to the sixth configuration, the following operation and effect are produced, and overlap with the operation and effect of the fourth configuration. The traveling vehicle B is a so-called power shovel. The excavator usually has a bucket at the tip of the bending arm B1. In addition, attachments such as a breaker, a pile driver, a clamshell, a log hand and the like in place of the bucket are prepared. That is, in the sixth configuration, a cleaning tool for a road drainage ditch is added as this attachment. Here, it is not necessary to explain that the refraction arm B1 of the power shovel can support the rake 3 so as to be able to move up and down similarly to the fourth configuration.
