る。Problems to be solved by the invention C] By the way, when cleaning work is continued in the road cleaning vehicle having the structure described in 1, the suctioned dirt and sand adhere to the inner walls of the suction nozzle 4 and the suction hose 6. However, as it accumulates, the suction area inside the nozzle or hose gradually decreases. Such a reduction in the suction area causes a decrease in suction efficiency, resulting in a problem of a decrease in cleaning efficiency.
従来、上記のように（＝Ｊ着した塵芥や土砂等を取り除
くため、第２図に示すように、吸込みノズル４のノズル
［」４ａに散水器１１を設けたものが提案されている。Conventionally, as shown in FIG. 2, it has been proposed to provide a water sprinkler 11 on the nozzle 4a of the suction nozzle 4 in order to remove the dust, dirt, etc. that have landed as described above.

て離脱させ、それらを洗い流す効果がある。In this structure, when water is discharged from the water sprinkler 11, the water becomes atomized by the circulating flow of air sucked from the blower nozzle 5 into the suction nozzle 4, and spreads all over the inside of the suction nozzle 4 and the suction bowse 6. is sucked into the nozzle 4 at high speed.
While moving inside the hose 6, the mist water flows through the nozzle 4.
This has the effect of removing dirt and dust that has accumulated inside the suction bowl 6 and washing it away.

気が付（ことが多くある。However, the judgment of whether the suction nozzle 4 or the suction hose 6 is attached has traditionally been based on the experience of the operator, and for this reason, the inside of the suction nozzle 4 or the suction hose 6 is completely blocked. It is often not until you are in a certain state that you realize something is wrong.

た。However, if the interior of the suction nozzle 4 or suction hose 6 is completely blocked and the suction action of air is lost, the water washing action by water spray will no longer function. It is necessary to scrape out the dust from inside the suction nozzle 4 and the suction hose 6 using a scraping stick or the like, which sometimes requires considerable effort.

起動信号となしたものである。In order to achieve the above object, the present invention provides a dust collection box and a fan having a suction port connected to the dust collection box at the rear of the vehicle body, and a nozzle [1 is a suction nozzle facing the road surface] on the dust collection box. At the same time, connect a blower nozzle whose nozzle opening faces the road surface at a position behind the suction nozzle (1) to the discharge port of the fan (2), and inject water into the nozzle to the nozzle opening of the suction nozzle. A water sprinkler is installed, and the fan operates to circulate air through the suction nozzle, the dust collection box, the fan, and the blower nozzle, and the dust on the road is blown up by the air jet from the blower nozzle, and the suction nozzle sucks it up and collects the dust. In a road cleaning vehicle housed in a box, a detector for detecting changes in internal pressure is provided on the air circulation path, and a detection signal from the detector is used as an activation signal for the water sprinkler.

洗いする。In the road cleaning vehicle with the above structure, if the inside of the suction nozzle and suction hose become clogged with dust or sand (=J),
The amount of air sucked by the vacuum fan decreases, and the internal pressure on the air circulation path changes. When this pressure change exceeds a predetermined range, a detector detects the change and at the same time activates a water sprinkler to wash the inside of the suction nozzle and suction hose.
