Title:
DUST COLLECTION COVER FOR CUTTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/057183
Kind Code:
A1
Abstract:
Dust collection covers for efficiently collecting dust are used in cutting machines used to cut stone and concrete. A dust collection cover of the present invention makes it possible to sufficiently collect dust by self dust collection without using a separate dust collector (forced dust collection). Two dust collection passages (11, 12) are provided within a dust collection cover. Coarse dust is collected in a first dust collection passage (11) on the outer periphery side, and fine dust is collected in a second dust collection passage (12) on the inner periphery side. The front end of a dust collection wall (13) that partitions the first dust collection passage (11) and the second dust collection passage (12) is positioned near a tangent line (S) that passes through a cutting site (C) so as to prevent coarse dust from rebounding.
