ELECTRIFIED WATER PARTICLE SPRAYING DEVICE

PROBLEM TO BE SOLVED: To provide an electrified water particle spraying device which is advantageous for suppressing generation of dust by a construction machine and improving work efficiency.SOLUTION: By excavating a ground G by a bucket 20 of a backhoe 10, dust is generated. An orientation control unit 38A controls an actuator 26 so that the direction of an electrified water particle ejecting unit 24 is directed to a place where dust specified by a generated portion identifying unit 28A is generated. The direction of the electrified water particle ejecting unit 24 is directed to the place where dust is generated. When a dust detection unit 30A detects dust, an operation control unit 38B turns on power supply of a pump 34 and a power source 36 for electrifying water and causes a dust suppression operation to be executed. Electrified water particles 2 ejected from the electrified water particle ejecting unit 24 are transported toward space S. The electrified water particles 2 that have reached the space S adsorb the dust in the space S by Coulomb force and then fall on the ground due to the weight of the electrified water particles 2 and the dust.SELECTED DRAWING: Figure 1 【課題】建設機械による粉塵の発生の抑制を図り作業効率の向上を図る上で有利な帯電水粒子散布装置を提供する。【解決手段】バックホウ１０のバケット２０によって地盤Ｇが掘削されることで粉塵が発生する。向き制御部３８Ａは、帯電水粒子噴出部２４の向きを発生箇所特定部２８Ａで特定された粉塵が発生する箇所に向けるようにアクチュエータ２６を制御する。帯電水粒子噴出部２４の向きが粉塵が発生する箇所に向けられる。粉塵検出部３０Ａが粉塵を検出すると、動作制御部３８Ｂは、ポンプ３４、帯電化電源３６の電源をオンさせ、粉塵抑制動作を実行させる。帯電水粒子噴出部２４から噴出された帯電水粒子２が、空間Ｓに向けて移送される。空間Ｓに到達した帯電水粒子２は、空間Ｓの粉塵をクーロン力によって吸着したのち、帯電水粒子２および粉塵の自重により地面に落下する。【選択図】図１
