Is connected to a frame 12 that is fixedly attached to the side portion of the arm, and its operating shaft 11B is connected to a cross rail portion 10A that is fixedly attached by bridging both arm portions of the arm 10.

Therefore, due to the expansion and contraction of the cylinder device 11, the arm 10 swings, whereby the position where the fifth wheel 9 is installed on the road surface (during normal running) and the position where the fifth wheel 9 falls to the vehicle body 3 side (slope surface). (While running) and is selectively rocked. The water sprinkler sprays a water tank 13 installed on the upper surface of the front part of the vehicle body 3 and sprays water stored in the water tank 13 from a nozzle provided on a rotary shaft 14 of a brush portion 4 of a rotary brush device 5. It is composed of a device (not shown).

On the other hand, the rotary brush device 5 includes a brush portion 4 constructed by implanting a large number of bristles 15 on an outer peripheral surface of a rotary shaft 14 extending in a substantially horizontal direction, and a motor 16 for rotationally driving the brush portion 4. The drive shaft of the motor 16 is directly connected to one end of the rotary shaft 14. Then, the brush portion 4 of the rotary brush device 5 is freely rotatable about a substantially vertical shaft passing through a substantially intermediate portion in the axial direction of the rotating shaft 14 and passes through a substantially intermediate portion in the axial direction of the rotating shaft 14 and the rotating shaft 14. Supporting means for freely swinging about a substantially orthogonal horizontal axis and slidably supporting along the axial direction of the rotary shaft 14, swiveling means for swiveling the brush portion 4, and swinging means for swiveling.
And a slide means for sliding.

The respective means are specifically configured as follows. That is, in FIGS. 4 to 7, the brush portion 4 has a first end in which both end portions are connected to both end portions of the rotating shaft 14.
Support bracket 17 is provided. An end portion of a substantially L-shaped second support bracket 18 is rotatably connected to an intermediate portion in the longitudinal direction of the first support bracket 17.

A rail device 19 extending in the left-right direction of the vehicle body 3 is provided as the sliding means on the bottom surface of the vehicle body 3 at a substantially middle portion in the front-rear direction.
Is rotatably supported on the bottom of the vehicle body 3 by the rotation support shaft 20. Further, the rail device 19 is provided with a pulling mechanism 22 by a wire 21. The rail device 19 includes the pulling mechanism 22 as the sliding means.
A traveling body 23 that slides along the rail direction is mounted by the. The traveling body 23 has the second
One end of the support bracket 18 is connected and supported so as to be swingable in the left-right direction of the vehicle body 3.

Therefore, when the traveling body 23 slides on the rail device 19, the brush portion 4 of the rotating brush device 5 is slid. Further, the rail device 19 includes an operating rod 24A of the cylinder device 24 as the turning means.
Is rotatably connected to the body 24 of the cylinder device 24.
The B base is rotatably connected to the vehicle body 2, and the extension / contraction operation of the cylinder device 24 causes the rail device 19 to pivot,
The brush part 4 of the rotary brush device 5 revolves.

Further, an operating rod 25A of a cylinder device 25 as the swinging means is rotatably connected to one side portion of the second support bracket 18, and the cylinder device 25
The base of the main body 25B is rotatably connected to the bottom of the rail device 19, and the expansion / contraction operation of the cylinder device 25 causes the brush portion 4 of the rotary brush device 5 to swing with respect to the rail device 19.

In FIG. 1, reference numeral 26 is a towing winch mounted on the rear portion of the vehicle body 3 and is used when the vehicle body 3 is towed from the top of the slope to perform work. The slope sweeper 1 having such a configuration is made to run on the slope when cleaning is performed as a pretreatment in the slope asphalt pavement construction, and the rotary brush device 5 is slid by the sliding means while water is sprinkled by the sprinkler, and the brush thereof is used. Cleaning is performed by rotating the part 4.

In this case, the slope is divided into a plurality of lanes extending in the circumferential direction from the top to the bottom of the slope, and the cleaning is performed while the slope sweeper 1 travels in the circumferential direction of each lane. Since the slope angle of the slope is different for each lane, the brush portion 4 of the rotary brush device 5 is swung and swung according to the slope shape. The slope sweeper 1 having such a configuration has the following advantages (1) to (4). (1) Since cleaning can be performed by traveling on a slope, cleaning work on the slope can be performed without relying on human power,
It can save labor, time and cost, and is excellent in safety. (2) The rotating shaft 1 is provided with the brush portion 4 of the rotating brush device 5.
4 is swung about a substantially vertical axis passing through a substantially intermediate portion in the axial direction, and is swung about a horizontal axis passing through a substantially intermediate portion in the axial direction of the rotary shaft 14 and substantially orthogonal to the rotary shaft 14. By swinging and swiveling the brush portion 4 of the rotary brush device 5 according to the shape of the slope, the brush 4 can effectively contact the slope and the cleaning performance can be improved. (3) The rotating shaft 1 is provided with the brush portion 4 of the rotating brush device 5.
Since it is configured to slide along the axial direction of 4, it is possible to take a large cleaning width of the slope by the sliding operation of the brush portion 4, and it is not necessary to frequently move the cleaning place, which is excellent in workability. . (4) In addition to the pair of steering wheels 7 and the pair of drive wheels 8, the self-propelled vehicle is provided with a fifth wheel 9 for assisting slope support which extends laterally from one side portion of the vehicle body 3. Therefore, the vehicle body 3 can be supported more stably on the slope, and in particular, the fifth wheel 9
Since it has a foldable configuration, it can be folded down and stored on the vehicle body 3 side during general traveling, and it does not get in the way during general traveling.

[0017]

As described above, according to the first aspect of the invention, the cleaning work on the slope can be performed without relying on the human power, the labor can be reduced, the time and the cost can be reduced, and the safety can be improved. In particular, the brush portion of the rotary brush device is effectively brought into contact with the slope, cleaning performance can be improved, and workability is excellent.

According to the invention of claim 2, the vehicle body can be supported more stably on the slope. According to the invention of claim 3, since the fifth wheel has a retractable structure, the fifth wheel can be tilted toward the vehicle body for storage during general traveling, and can be kept out of the way during general traveling.
