特開2006−28948号公報JP 2006-28948 A

しかしながら、特許文献1の側溝切断機は、ブレードに給水することで、粉塵の飛散を抑制できるものの、給水された水は、粉塵が混入された汚染水となる。この汚染水の処理は、多大な労力を必要とし、作業効率を低下させていた。   However, although the gutter cutting machine of Patent Document 1 can suppress the scattering of dust by supplying water to the blade, the supplied water becomes contaminated water mixed with dust. The treatment of this contaminated water requires a great deal of labor and has lowered the work efficiency.

本発明は、側溝の側壁に水平方向に延びる切り込みを入れるときに、汚染水を発生することなく、粉塵の飛散を抑制し、作業効率を向上することができる乾式水平切断機を提供することを目的とする。   The present invention provides a dry horizontal cutting machine capable of suppressing dust scattering and improving work efficiency without generating contaminated water when a cut extending in the horizontal direction is made in the side wall of the side groove. Objective.

A base that holds the cutter slidably in a horizontal direction in a state where the blade is horizontal,
The cutter has a cover that covers a part of the peripheral edge of the blade;
The cover covers a portion of the peripheral edge of the blade that is not inserted into the side wall from the vicinity of the side wall in a state where the blade is inserted into the side wall,
A dry horizontal cutting machine further comprising a suction unit connected to the cover and sucking dust that is generated when the blade cuts the side groove and scatters inside the cover.

(1)の発明によれば、乾式水平切断機は、側溝の側壁に水平方向に延びる切り込みを入れ、カッタと、ベースと、吸引部と、を備える。
カッタは、円形状に形成され、回転した状態で周縁が側壁に当接されることで、側溝を削りながら側壁に挿入され、側壁に切り込みを入れる刃を有する。
ベースは、刃を水平にした状態でカッタを水平方向にスライド自在に保持する。
また、カッタは、刃の周縁の一部を覆うカバーを有する。
このカバーは、刃が側壁に挿入された状態において、刃の周縁のうち、側壁に挿入されていない部分を、側壁近傍から覆う。
吸引部は、カバーに接続され、刃が側溝を削ることにより発生してカバー内部において飛散する粉塵を吸引する。
According to the invention of (1), the dry horizontal cutting machine is provided with a cutter, a base, and a suction portion, with a cut extending in the horizontal direction in the side wall of the side groove.
The cutter is formed in a circular shape, and has a blade that is inserted into the side wall while cutting the side groove, and has a notch in the side wall, while the peripheral edge is in contact with the side wall in the rotated state.
The base holds the cutter slidable in the horizontal direction with the blade horizontal.

そして、カッタ30の刃32の回転を開始し、吸引部40の吸引を開始し、刃32を側溝50の側壁51に当接させ、乾式水平切断機1を後側から前側に移動させることで、側溝50の側壁51に水平方向に延びる切り込みが入る。
このとき、刃32により側溝50が削れられることにより発生した粉塵は、カバー33内部に飛散し、カバー33の吸引口331aから吸引部40により吸引される。
Next, the inner cover 332 is protruded from the inside of the outer cover 331 of the cutter 30, and the elastically deformable portion 333 is pulled out from the inside of the inner cover 332.
Then, rotation of the blade 32 of the cutter 30 is started, suction of the suction portion 40 is started, the blade 32 is brought into contact with the side wall 51 of the side groove 50, and the dry horizontal cutting machine 1 is moved from the rear side to the front side. A cut extending in the horizontal direction is made in the side wall 51 of the side groove 50.
At this time, dust generated by cutting the side groove 50 by the blade 32 is scattered inside the cover 33 and sucked by the suction portion 40 from the suction port 331 a of the cover 33.

本実施形態に係る乾式水平切断機1によれば、以下の作用効果を奏する。
乾式水平切断機1によれば、刃32の周縁のうち、側壁51に挿入されていない部分を、側壁51近傍から覆うカバー33を設けたことで、カッタ30の刃32により側溝50を削ることで発生した粉塵は、カバー33内部に飛散する。そして、このカバー33内部に飛散した粉塵は、吸引部40により吸引される。
したがって、側溝50の側壁51に水平方向に延びる切り込みを入れるときに、給水せずに、粉塵を処理するので、汚染水を発生することなく、粉塵の飛散を抑制し、作業効率を向上することができる乾式水平切断機1を提供できる。
The dry horizontal cutting machine 1 according to the present embodiment has the following operational effects.
According to the dry horizontal cutting machine 1, the side groove 50 is shaved by the blade 32 of the cutter 30 by providing the cover 33 that covers the portion of the peripheral edge of the blade 32 that is not inserted into the side wall 51 from the vicinity of the side wall 51. The dust generated in is scattered inside the cover 33. The dust scattered inside the cover 33 is sucked by the suction unit 40.
Therefore, when the cut extending in the horizontal direction is made in the side wall 51 of the side groove 50, the dust is processed without supplying water, so that the scattering of the dust is suppressed and the working efficiency is improved without generating contaminated water. It is possible to provide a dry horizontal cutting machine 1 capable of

また、乾式水平切断機1によれば、カバー33の側壁51近傍側に弾性変形可能な素材で形成された弾性変形可能部333を配置することで、カバー33を側壁51に当接させても、側溝50や乾式水平切断機1が損傷することがない。また、カバー33を側壁51に当接させることで、より確実に粉塵がカバー33の外部に飛散するのを防止できる。   Further, according to the dry horizontal cutting machine 1, the cover 33 can be brought into contact with the side wall 51 by disposing the elastically deformable portion 333 made of an elastically deformable material near the side wall 51 of the cover 33. The gutter 50 and the dry horizontal cutting machine 1 are not damaged. In addition, by bringing the cover 33 into contact with the side wall 51, dust can be more reliably prevented from scattering outside the cover 33.

なお、本発明は前記実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。   It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
