Description

Building tools, dust absorbers, tile tools, auxiliary tools for electric grinder cutters, dust collectors, building tools, plastering tools, civil engineering tools, block tools, sheet metal tools, mechanical tools, etc.

Dust and dust are polluted not only by the person but also by the surrounding people, and in recent years it has been an urgent issue to be corrected in urban areas.

When cutting wet materials such as tiles, stones, blocks, concrete, etc. with a small electric grinder cutter (hereinafter referred to as a small electric cutter), and when cutting iron, aluminum, etc., be sure to use dust, iron powder or dust. Etc. have occurred.

The use of a small electric cutter is said to be necessary and maneuverable because of its good turning, and is considered to be inconvenient for a large-scale equipment only for handling dust.

In the case of cutting a fixed-size object at a fixed position and location, although the protection of dust and dust is improving year by year, considering the mobility of a small electric cutter, such a fixed position and location The cutting process is not always performed.

Absorption of dust and dust transmitted to the bottom of the groove after cutting is the most difficult problem that has not been solved by conventional dust absorbers.

Conventionally, there has been a metal cover that acts to prevent dust and dust from directly colliding with an operator's face.

The dust collector absorbs 99% of the dust, dust, etc. that accompany the cutting process of everything.

Due to the nature of mobility, it is best not to equip anything, but that doesn't mean that dust and dust can be scattered. It is the lightest possible and remains easy to use while leaving it out of the way. Deal with dust.

When processing distorted curves, circles, ellipses, etc., you must normally use it as a small electric cutter.

Small electric cutters are also called hand cutters, and they are often used with the same level of elasticity and are not often used to cut things at the same position. Even if it is a scene, it is meaningless unless it can prevent dust and dust from spreading.

Each manufacturer is hurting their heads to deal with dust and dust that crawls at the bottom of the groove after cutting, as well as dust and dust from the cutting edge. I came to the conclusion that I had no choice but to deal with it.

A metal cover that is directly exposed to dust or dust is practically too narrow to cover.

There are two types of dust and dust scattering, one that is pushed directly back by cutting and the other that is scattered backward through a narrow groove in the cut end. Most dust, dust, etc. are absorbed by a double dust suction device consisting of a dust suction hose and a dust cover bag. This is a structure that has not yet been discovered in the world.

The present invention is not difficult to use if it is made of iron or stainless steel as the main structural bar and made of light, rubber, cloth, or plastic.

One-touch is an absolute requirement for attachment and removal, and the device of the present invention should not significantly impair the original workability of a small electric cutter.

For dust and dirt flowing at a low position along the cut groove, the dust bag must be spread to a position where the momentum of the airflow flowing while the momentum of the drill rotation is reduced.

In order to cut while looking at the cutting line, the line of sight of the face must be moved slightly away from the cover, so the current metal cover width is completely useless, and in order to avoid dust and dust, It was found that it was necessary to extend the dust suction port with a transparent cover.

When cutting tiles with a small electric cutter so far, there are many examples of dusting and dusting work. To remove it, hold the dust collector hose separately and place it on the cut end. You need someone to get it. Also, it is dangerous to work with one dust collecting hose and one small electric cutter alone, and clean cutting is impossible. With this product, even a single person can hold a small electric cutter firmly with both hands to perform safe and stable cutting, and dust and dust hardly spread due to the double structure.

The small electric cutter does not have a guide for cutting mainly, and it is more difficult to see the line drawn on the object than to look away from the metal cover that protects against dust and dust. It will be white when exposed to dust and dust, and it will be necessary to cut the eye with a narrowed eye, but by extending the transparent dust suction port, the eyes can be fully opened and cut. Become.

A screw hole is attached to the metal cover (Fig. 1) 3 of the main body to prevent dust and dirt from directly falling on the face attached to the small electric cutter. 1) The transparent cover 4, the dust suction port 5, the dust suction hose 6, the dust suction cloth cover bag (Fig. 3) 5, and the dust collection port 7 (Fig. 1) where the dust merges are integrated. Because of its light weight, it can be attached and detached with a single touch.

Dust absorption with a transparent cover (Fig. 1) 4 formed at the tip along the semicircle of the existing metal cover so that the cut line can be identified while suppressing dust scattering while being made of transparent plastic apparatus.

When cutting, a circular dust suction port (Fig. 1) that is made continuously from a transparent cover with rubber, plastic, etc. as a means to directly absorb dust, chips, dust, etc. 5 or connected with a connecting cloth tape or the like, and added with flexibility of movement up and down, left and right, and connected to 6 of the next dust absorption hose (FIG. 1) with a connecting cloth tape or the like.

The bottom of the dust suction hose connected to the dust suction port (5) in Fig. 1 and the connecting cloth tape is uniformly cut to a width of 50 mm, making it easier to absorb dust, chips and dust scattered from the middle. A dust suction device that attaches to the dust collecting port of the connecting part where the plastic dust at the end merges with a connecting cloth tape and sends the dust etc. to the dust collecting hose.

The entire dust collector is connected to the central portion of the main body small-sized electric cutter body and the dust suction hose with a connecting cloth tape because it is necessary to prevent the entire dust collection device from moving unnecessarily when cutting.

Claims (1)

Small electric grinder cutters (hereinafter referred to as small electric cutters) on site and in factories, cutting tiles, concrete, blocks, exterior boards and their processed products, as well as diamond cutter rotary blades, etc. When cutting with, most of the dust and chips and dust that come out automatically are sent to the dust collecting hose connected to the dust collector without leaking outside, and dust is also scattered around the operator's eyes, mouth and nose. To prevent this, attach a plastic transparent cover to the existing iron cover attached to the small electric cutter with a flexible and easy-to-remove connection cloth tape, and use it together with a dust suction port or a connection cloth. It is made of spiral rubber or plastic, 400mm long and 100mm in diameter, made of iron, stainless steel or plastic as the main memory of shape memory. Connected to a duct-like dust suction hose or a duct-like spiral dust suction hose that does not require a shape memory main line, and the bottom of the dust suction hose is about 50 mm in width from the dust suction port to the dust collection port. Cut up to the connecting joint and open it, connect the dust collection hose and the rear end of the dust collection port connected with the connection cloth tape to the dust collection hose from the dust collector, and add a thicker fabric to the dust collection hose. A dust-absorbing cloth cover bag is used to cover the upper surface and the left and right sides of the cover with glue, bond, or connecting cloth tape, etc. In addition, dust, chips, and dust that are fed backwards through the groove that has been cut at the same time while cutting, touch the remaining part of the fabric to the ground, ground, or leave no gap on the table By cutting while placing The dust absorbing hose cover bag prevents the dust, chips, and dust from leaking out of the bag by losing momentum from the groove by adsorbing, rubbing, and shielding the cloth, and the bottom of the dust absorbing hose is opened as it is. A double-type dust suction device that is sent to the dust collector from the dust collection port and dust collection hose via the part.
