【発明が解決しようとする課題】大型掃除車の集塵用回
転ブラシは常時地面等と接地する状態で保持され、従っ
て不使用時でも毛先が接地したまま放置されているため
ブラシが座屈して変形し、再び使用するときに、ブラシ
の先端が地面等に確実に接地しないことがあり集塵機能
を損なう。The rotary brush for dust collection of a large-sized vacuum cleaner is always kept in contact with the ground or the like. Therefore, even when not in use, the brush buckles because the tip of the brush is left grounded. When the brush is used again, the tip of the brush may not reliably contact the ground or the like, which may impair the dust collecting function.
【０００４】又、使用場所まで回転ブラシと地面等が接
触したまま移動するため回転ブラシの摩耗が著しく、メ
ンテナンスに費用及び時間がかかる。In addition, since the rotary brush is moved to the place of use while keeping the rotary brush in contact with the ground or the like, the rotary brush is significantly worn and maintenance costs and time are required.
【０００５】そこで、本発明は回転ブラシを使用しない
移動時又は停止時には地面等と接地しないように回転ブ
ラシを引上げ、保持することで回転ブラシの摩耗や悪い
癖がついて変形することを防ぎ、集塵機能を損なうこと
なく、耐久性を高めることを目的とする。Accordingly, the present invention prevents the rotating brush from being deformed due to abrasion or bad habit of the rotating brush by lifting and holding the rotating brush so as not to touch the ground or the like when moving or stopping without using the rotating brush. The purpose is to increase durability without impairing performance.
【０００６】さらに、回転ブラシの上下操作を簡易、か
つ、迅速に行えるようにした。Further, the up and down operation of the rotary brush can be performed simply and quickly.
