Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a dust bag protection device.

[Background of the idea]

BACKGROUND ART Conventionally, when wood is processed using a woodworking machine (planer, saw, etc.), there are cases in which the cutting waste produced by the processing is sucked up by a dust collector. In this case, the dust collector may be used by connecting a dust bag for collecting cutting waste to the side of the dust collector body.

Conventionally, the dust bag attached to these dust collectors was attached directly to the exhaust port of the dust collector, so if large pieces of wood were mixed in with the discharged cuttings, they would be pushed onto the inside of the dust bag. Direct contact caused problems such as damage to objects that were in contact with the outer surface of the dust bag or injury to people who were in contact with the outer surface of the dust bag.

[Purpose of invention]

The purpose of the present invention is to eliminate the problems of the prior art described above and to improve the safety of dust collection work.

[Summary of the idea]

The present invention proposes that by installing a pipe member between the outlet of the woodworking dust collector and the dust bag to guide the sucked cuttings toward the bottom of the dust bag, it is possible to prevent large pieces of wood from directly hitting the inner surface of the dust bag. Focusing on things that can be prevented, the relationship between the dust collector, dust bag, and pipe members has been devised.

[Example of idea]

An embodiment of the present invention will be described with reference to FIG.

1 is a dust collector. 1c is the suction port of a dust collector that is normally connected to the cutting waste outlet of a woodworking machine, 1a is the discharge port of the dust collector that conveys the cutting waste sucked in from the suction port 1c to the next stage, and 1b is the side surface of the discharge port 1a. This pin 1b constitutes a guide groove 2b and attachment/detachment means, which will be described later.

Further, numeral 3 is a dust bag for collecting cutting waste discharged from the discharge port 1a, and is provided with a handle 3a for transporting the dust bag and a fastener 3b for taking out cutting waste.

A pipe member 2 is interposed between the dust collector 1 and the dust bag 3 and connects the two, and has a bent part 2a formed on the side to be inserted into the dust bag 3, and is connected to the discharge port 1a. By guiding the hook-shaped guide groove 2b provided on the side with the pin 1b and connecting it to the dust collector 1, the pipe member 2 can be attached with the discharge port facing toward the bottom of the dust bag 3.

Therefore, in the above configuration, when dust collection is performed, the cutting chips 4 discharged from the discharge port 1a of the dust collector 1 hit the bent portion 2a of the pipe member 2, and the debris 4 hits the bottom surface of the dust bag 3 with its force weakened. Since the cutting chips 4 are dropped, there is no possibility that the cutting chips 4 directly hit the inner surface of the dust bag 3 with force and damage those that were in contact with the outer surface of the dust bag 3, as in the conventional case.

[Effect of idea]

According to the present invention, in a dust bag that is connected to an outlet of a woodworking dust collector and collects cuttings conveyed from the dust collector, at least a portion connected to the outlet of the dust collector is formed into a cylindrical shape. A pipe member formed in the dust collector is detachably connected to the pipe member, a bending part is provided on the side of the pipe member to be inserted into the dust bag, and the pipe member is connected to the dust bag through an attachment/detachment means provided at the connection part between the outlet of the dust collector and the pipe member. By attaching the pipe member to the discharge port of the dust collector, the discharge port of the pipe member is regulated toward the bottom of the dust bag, so even if cuttings such as large pieces of wood are sucked in, the buffering effect of the pipe member will prevent It reduces the force of the cutting debris, guides the cutting debris toward the bottom of the dust bag, and eliminates pieces of wood that come into direct contact with the inner surface of the dust bag, solving the problems of the conventional method with an extremely simple configuration. can.

[Brief explanation of the drawing]

Claims (1)

[Claims for Utility Model Registration] In a dust bag that is connected to an outlet of a woodworking dust collector and collects cuttings conveyed from the dust collector, at least a portion connected to the outlet is connected to the outlet of the dust collector. Attachment/detachment means for detachably connecting a cylindrical pipe member, having a bent part on the side of the pipe member to be inserted into the dust bag, and providing a connecting part between the outlet of the dust collector and the pipe member. A dust bag protection device, characterized in that the pipe member is attached to the discharge port of the dust collector through the pipe member, so that the discharge port of the pipe member is regulated toward the bottom surface of the dust bag.
