Title:
WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/014479
Kind Code:
A1
Abstract:
A work machine according to the present invention optimally collects work chips, such as dust, produced during work. In a circular saw 10, a sawdust discharge port 27H and a cover opening 27J are formed in an inner cover 27, and a dust collecting chamber inlet 62L1 and a dust collecting chamber outlet 62L2 are formed in a dust collecting case 60. With this configuration, it is possible to deliver sawdust in a tool accommodating space 28 into a dust collecting chamber 62J through the sawdust discharge port 27H and the dust collecting chamber inlet 62L1 and to deliver air AR1, which has been delivered into the dust collecting chamber 62J, toward the tool accommodating space 28 through the dust collecting chamber outlet 62L2 and the cover opening 27J. Furthermore, at least a portion of the dust collecting chamber inlet 62L1 and at least a portion of the dust collecting chamber outlet 62L2 are arranged at the same position in the vertical direction. Hence, it is possible to inhibit the sawdust discharged from the dust collecting chamber inlet 62L1 into the dust collecting chamber 62J from flowing back from the dust collecting chamber 62J to the dust collecting chamber outlet 62L2.
