Title:
AUXILIARY DEVICE AND WORK MACHINE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/230050
Kind Code:
A1
Abstract:
The present invention improves dust collection performance while suppressing an increase in body size. A dust collection device 40 comprises: an intake pipe 53 connected to a suction unit 52; a cyclone unit 60 that swirls air flowing out from the intake pipe 53 and centrifuges dust; and a filter unit 70 that accommodates a filter 72. The filter unit 70 has an outlet 74 connected to the cyclone unit 60 and discharging the air having passed through the filter 72. Therefore, the air and dust near a tip tool T can be separated by the cyclone unit 60. Furthermore, even when the dust remains, the remaining dust can be removed by the filter 72. Furthermore, the intake pipe 53 and the cyclone unit 60 are arranged at positions where the intake pipe 53 and the cyclone unit 60 overlap in a front-rear direction, and the filter unit 79 is disposed behind the cyclone unit 60. Therefore, as compared to a case where the filter unit 70 is disposed below the cyclone unit 60, an increase in the body size of the dust collection device 40 in the vertical direction can be suppressed.
