【発明が解決しようとする課題】しかしながら、上記の
岩盤清掃作業では次のような課題がある。However, the above-described bedrock cleaning work has the following problems.

スの引き回し等ホース処理に多大な人力を必要とする。Further, in the bed surface cleaning device described in Japanese Patent Laid-Open No. 9-32033, the scrap collecting machine and the vacuum tank are not separated and integrated, but are connected by a water hose and a vacuum hose. . For this reason, a great deal of human power is required for hose processing such as routing of the hose.

招いている。Further, in the green cut surface misalignment recovery devices disclosed in Japanese Patent Laid-Open No. 6-26024 and Japanese Patent Laid-Open No. 8-232474, the vacuum device and the tank are mounted on the trolley, and it is not necessary to pull the hose. Since the cleaning water in the sludge collection tank is recycled or forcedly drained by the drainage pump, the collected sludge is concentrated and compacted on the bottom of the sludge collection tank, which makes it difficult to drain the earth and sand, resulting in a decrease in work efficiency.

力による仕上げ清掃を実施せざるを得なく、作業効率が
低下する。Further, in the above-mentioned cleaning machine, since the scrap recovery unit also having a green cutting function is provided with the rotating mechanism, a slight cleaning scrap is regenerated by the rotation of the brush, and the uncleaned sand remains. For this reason, finally, it is unavoidable to manually perform the final cleaning again, and the work efficiency is reduced.

しやすい。In addition, since the sliding recovery section is provided with the rotating brush mechanism, the sliding suction section becomes large, the mechanism is complicated, the air flow inside the sliding recovery section is obstructed, and the required wind speed cannot be maintained. The scrap collection rate decreases, and uneven cleaning is likely to occur.

を実施しなければならない。Further, since the scrap collecting section is provided within the width of the vehicle, the traveling device (tires or crawlers) of the base machine travels again on the cleaning surface when moving forward,
After cleaning, the rock surface may be damaged, and the dirt attached to the traveling equipment may stain the cleaning surface, so that the final cleaning must be performed manually again.
