2. Description of the Related Art Conventionally, there is a road cleaning vehicle having a structure shown in FIG. 3 as a road cleaning vehicle used for cleaning paved surfaces such as asphalt roads. This road cleaning vehicle is equipped with a garbage collection box 2 at the rear of a traveling vehicle body 1, and a vacuum fan 3 having a suction port 3a connected to the garbage collection box 2. A facing suction nozzle 4 is connected via a suction hose 6, and a blowing nozzle 5 whose nozzle opening 5a faces the road surface A is connected to the discharge port 3b of the vacuum fan 3 at a rear position of the suction nozzle 4. Further, a rotary brush 7 and a water sprinkling nozzle 8 are provided at the lower part of the traveling vehicle body 1, located in front of the suction nozzle 4. It is connected to a water tank 10 provided therein.

By the way, in the road cleaning vehicle having the above structure, in order to efficiently suck up dust through the suction nozzle 4, it is necessary to adjust the angle of air injection of the blower nozzle 5 to the road surface A within an appropriate range. That is, if the above-mentioned angle is not appropriate, the air jet flow escapes to the front of the suction nozzle 4, and the dust is blown away to the vicinity of the nozzle opening 4a of the suction nozzle 4, resulting in a problem that the suction efficiency is significantly deteriorated.
この発明は、上記の不具合に鑑みてなされたも

ている。 As shown in FIGS. 1 and 2, the suction nozzle 4 is located near the nozzle opening 4a of the suction nozzle 4.
A blower frame 11 surrounding the front and rear sides is attached. A flexible ventilation hose 12 connected to the discharge port 3b of the vacuum fan 3 is connected to the upper part of the ventilation frame 11, and the bottom plate 11' of the ventilation frame 11 is connected to the front and rear of the nozzle opening 4a of the suction nozzle 4. Air blow nozzle ports 13 and 14 are provided at the respective locations.

てもよい。 This embodiment has the above-mentioned configuration, and when the suction nozzle 4 is about to pass over the dust accumulated on the road surface A, the air flow jetted from the front nozzle port 13 loosens the dust, and the rear nozzle It is made to float by the jet air flow from the mouth 14. At this time, the airflow ejected from the rear side is prevented from blowing away forward by the airflow ejected from the nozzle port 13 on the front side, and thereby the dust is carried below the nozzle port 4a of the suction nozzle 4. It is absorbed efficiently. In addition, the jet air flow coming out from the front nozzle port 13 is directed to the guide blade 15.
Since the dust is directed toward the suction nozzle 4, the blowing of dust forward from the air blowing frame 11 is reliably stopped, and dust and the like are prevented from flying up, allowing clean cleaning work to be performed. In the above embodiment, the blower frame 11 is provided to combine the front and rear blower nozzles, but separate blower nozzles may be provided before and after the suction nozzle.

掃車にも本発明を適用することができる。 In addition, although we have shown a road cleaning vehicle that uses a vacuum fan 3 to blow and suck air from the blower nozzle and suction nozzle, an air circulation system is used. The present invention can also be applied to a cleaning vehicle configured to blow air using an independent mechanism.
以上の説明したように、この発明は、吸込みノ

As explained above, in this invention, air blowing nozzles are provided before and after the suction nozzle to prevent the air jet from the rear air blowing nozzle from being blown away forward, thereby preventing dust from dispersing to the outside. This allows the suction nozzle to suck it up efficiently, allowing for efficient cleaning work.
