Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a dust collector that can perform work while collecting shavings generated when grinding building materials such as ALC plates and gypsum boards with a dust collector. Regarding file tools.

[Conventional technology]

As is generally known, at construction sites,
The length, width, and shape of building materials such as gypsum board are processed each time. As a processing means of the building material at that time, a grinding process with a file may be used. According to this processing means, it is possible to accurately process into a required shape, and the processed surface is also very beautiful.

[Problems to be solved by the device]

However, according to the above-mentioned conventional technique, since the building material is ground by a file, a large amount of extremely fine shavings are generated. Then, there is a problem that the shavings are scattered in the air to deteriorate the working environment and enter the human body to impair health. There is also a problem that the shavings spread on the floor and the floor becomes slippery, and the slip is likely to cause an injury. Furthermore, since the shavings are extremely fine, it is difficult to clean them, and therefore, there is a problem in that cleaning after the work is troublesome.

[Means for Solving the Problems]

The dust collecting file of this invention was made in view of the above circumstances, and the specific means is to install a dust collecting hose connected to the dust collector on one side and to the other side. In a dust file comprising a shell provided with a suction port, and a mesh file attached to the suction port of the shell, the mesh file includes a large number of claw-shaped projections,
A plurality of holes are provided corresponding to each of the claw-shaped projections and adjacent to the rising portion of the claw-shaped projections.

[Action]

When the building material is ground by using the dust collecting tool by the above means, the building material is scraped off by the claw-like projection while moving the dust collecting tool in the direction opposite to the claw-like projection of the mesh file. The shavings of the building material generated here are generated at the rising portions of the claw-shaped projections corresponding to the claw-shaped projections, and at the same time, the shavings are generated by the suction force of the dust collector. Through the holes adjacent to the front of the shell, through the suction port of the shell, the inside of the shell, and the suction port of the shell, all are sucked and collected into the dust collecting hose and the inside of the dust collector.

〔Example〕

An embodiment of the dust collecting file of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 3, the dust collecting file 1 of this embodiment has a mesh file 2, a dust collecting hose 3, and the mesh file 2 mounted on one side, and the dust collecting hose 3 And a shell body 4 mounted on the other side.

The mesh file 2 includes a large number of claw-shaped projections 5 and a plurality of holes 6 corresponding to each of the claw-shaped projections 5 and formed adjacent to the rising portions of the claw-shaped projections 5. It is a plate-shaped file. One hole is always formed corresponding to one claw-shaped projection. One of the dust collecting hoses 3 is connected to the shell 4 and the other is connected to the dust collector C. Since the dust collecting hose 3 is used by being bent at various angles according to the movement of the dust collecting file tool 1, a flexible one such as a bellows is suitable. The shell body 4 is a mesh file 2
Is equipped with a suction port 7 on the side where it is mounted, and a suction port 8 on the side to which the dust collecting hose 3 is connected. The shell 4 has a substantially funnel shape in which the side to which the mesh file 2 is attached is large and the side to which the dust collecting hose 3 is connected is small. It is preferable that the suction port 7 has such a size that the suction port 7 is hidden by the mesh file 2 when the mesh file 2 is attached to the shell body 4. Further, the suction port 8 is preferably of a size that allows the dust collecting hose 3 to be fitted on the outside.

A procedure for using the dust collecting file 1 having the above configuration will be described.

First, the other side of the dust collecting hose 3 is connected to the dust collector C. Then, the dust collector C is turned on and operated to bring the inside of the shell body 4 and the dust collecting hose 3 into a negative pressure state to generate a suction force. On the other hand, as a reference for grinding, a portion to be ground a of the building material A (3rd
Marks D and the like are put in the one-dot chain line portion in the figure). When grinding the building material A with this dust collecting tool 1, first,
The mesh file 2 of the dust collecting file 1 is brought into contact with the ground portion a of the building material A. Then, the dust collecting file 1 is moved in a direction against the claw-shaped projections 5, and the building material A is scraped off by the claw-shaped projections 5. As a result, shavings B of the building material A are generated at the rising portions of the claw-shaped projections 5 corresponding to each claw-shaped projection 5. The shavings B are generated by the suction force of the dust collector C from the holes 6 adjacent to the rising portions of the claw-shaped projections 5 to the suction port 7 in correspondence with each of the claw-shaped projections 5 at the same time. Be sucked. This shavings B sucked into the suction port 7 is the shell 4
It moves through the inside to the suction port 8 and is sucked into the dust collecting hose 3. Then, the shavings B sucked into the dust collecting hose 3 pass through the inside thereof and are collected and accumulated in the dust collector C. As described above, since the dust collector C is constantly operated while the grinding work is repeated to scrape off the portion a to be ground, the shavings B are collected in the dust collector C at the same time as they are generated. Therefore, the shavings B are not scattered in the air or spread on the floor.

In addition, as another embodiment, several kinds of mesh files 2 having claw-shaped projections 5 having different shapes and arrangements are prepared, and when the grinding amount is large, the rough mesh file 2 is used for grinding and grinding. When the amount becomes small, the fine ground mesh file 2 is used to finish the ground surface. In this case, the mesh file 2 is detachably attached to the shell body 4. As described above, the work efficiency and the finish state are improved by appropriately selecting and using the mesh file 2 according to the use conditions.

[Effect of device]

As is clear from the above description, the dust-collecting file tool of the present invention causes shavings due to the grinding work of grinding the building material with a large number of claw-shaped projections of the mesh file, at the same time,
By operating the dust collector, the shavings of building materials are sucked into the suction port of the shell, the inside of the shell, and the suction port of the shell through the holes of the mesh file, and from there, through the dust collecting hose to ensure that all dust collectors are collected. As it is inhaled, shavings are not scattered in the air. Further, since the shavings do not fall on the floor, the floor is not soiled and the labor for floor cleaning is saved. Furthermore, it is possible to perform an efficient work according to the grinding amount and the finishing state by appropriately selecting a mesh file having different shapes and arrangements of the claw-shaped projections.
