  Dirty soil, straw scraps, and the like fall and adhere to the road surface where the agricultural machine, the construction machine, and the like have traveled, and therefore, a spiral brush roller is often used to clean these garbage. However, it is difficult to complete the cleaning of the dust scattered on the road surface wider than the travel width of the machine body of the vacuum cleaner only once, and sweeps the dust to the side edge of the road surface width while traveling multiple times or reciprocally. There are many cases. In such a case, the spiral brush roller that spirals in one direction can be rotated forward and backward to sweep up to the left or right side with respect to the traveling direction. Then, in addition to the switching operation mechanism for switching the rotation direction of the brush roller between the normal rotation direction and the reverse rotation direction, a switching transmission mechanism and the like are required, and the configuration becomes complicated.

By reversing, it is possible to sweep toward the same side of the road by a cleaning operation such as traveling back and forth on the same road surface. In addition, since these brush rollers 1 and 2 are rotated at the ground contact portion toward the side where the front side portion rises, the garbage swept from the road surface is subjected to the left feed or right feed action in the floating state. Then, it is conveyed to the ends of the brush rollers 1 and 2 so that efficient cleaning can be performed. Although the pair of upper and lower brush rollers 1 and 2 is used, the use period can be lengthened accordingly, and the transmission mechanism, operation, and the like can be simplified.

  According to the second aspect of the present invention, the left feeding brush roller 1 and the right feeding brush roller 2 can be moved up and down with respect to the machine body 3 and can be turned upside down. In the ascending / descending position, it is possible to easily move and travel in the non-cleaning action posture, and to easily perform the reverse switching action of the brush rollers 1 and 2. In addition, when the upside down switching is performed in the non-cleaning action posture in which the brush rollers 1 and 2 are lifted during the cleaning operation process, the reverse switching operation can be easily performed without the ground resistance of the brush rollers 1 and 2. In addition, the number of operations can be reduced and performed accurately.

  According to the third aspect of the present invention, the dust attached to the brushes of the brush rollers 1 and 2 is easily washed away by the flow of water spray, and the cleaning effect of the brush can be maintained well. The humidification effect of the scattered dust can be improved, and the dust scattering prevention effect can be enhanced.
