Abstract

PURPOSE:To treat conveniently deposited dust by providing an opening at a part of the primary dust collecting plate in the vicinity of the primary dust collecting lid, placing a dust box directly below the plate, and arranging the box freely drawable from the same surface as the dust collecting lid in a dust collector. CONSTITUTION:An air current is generated in the direction as shown by the arrow by operating a grinder motor 1 and a dust collecting motor 12 with a switch. The heavy-weight materials such as coarse dust and sparks are deposited on the primary dust collecting plate 8 by the grinding action of a grindstone 2, or collected into a dust box 7 directly below the plate 8. Meanwhile, fine dust is allowed to flow into a filter 9, filtered, and collected, and the purified air is discharged from a discharge port 13. When a large amt. of dust is deposited on the primary dust collecting plate, the primary dust collecting lid is removed, the dust box which is arranged in the same direction as the lid 14 is drawn out, and the deposited dust is scraped out.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a dust collector, and particularly to a dust collector suitable for collecting dust generated during grinding work or the like.

[Background of the invention]

This type of dust collector generates a large amount of sparks at the same time as dust, so a primary dust collection plate M is placed over the dust collection filter to prevent it from burning out, and coarse dust and sparks are deposited on top of it. I try to do that.

Since this dust causes a reduction in the amount of suction air, it is necessary to remove this accumulated dust at regular intervals.

In this case, remove the lid of the primary dust collection section, prepare a dust receptacle on the floor, scrape out the accumulated dust, or dispose of the dust that has fallen onto the spherical surface with a vacuum cleaner, etc. It was requested. However, in either case, the process was time-consuming and extremely inefficient.

[Purpose of the invention]

An object of the present invention is to provide a dust collector that can handle accumulated dust simply and efficiently.

[Summary of the invention]

In the present invention, a hood 3 that covers the grinding wheel 2 disposed on the dust collector body 6 is provided in communication with the inside of the dust collector body 6, and a space in which the hood 3 communicates with a space having a dust collection filter 9 are provided. In a dust collector provided with a primary dust collection plate 8 divided into upper and lower parts, and a primary dust collection lid 14 that opens and closes a space with which the hood 3 communicates, the first dust collection plate 8 is divided into upper and lower parts. Next, an opening is provided in a portion close to the dust collection lid 14, and
By arranging the dust box 7 directly below the dust collector and making it possible to freely pull out the dust box 7 from the same surface as the primary dust collection lid 14, the accumulated dust can be easily disposed of. This is how it was done.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 3. The dust collector for a grinder has a grinder motor 1 mounted on the upper part of the dust collector body 6, a grinding wheel 2 attached to both sides of the rotating shaft, and a hood 3 covering the grinding wheel 2.
This hood 3 is communicated with the inside of the dust collector main body 6 from the -L side. This allows the grinder powder to be directly suction-filtered through the main body 6 without using a duct or the like. The inside of the dust collector main body 6 is divided into upper and lower parts by a primary dust collector plate 8. A primary dust collecting section lid 14 that opens and closes the space above the primary dust collecting plate 8 is provided on the side surface of the main body 6. An opening is provided in a portion of the primary dust collecting plate 8 that is close to the lid 14 . A dust box 7 is arranged directly below it. The dust box 7 can be pulled out from the same side as the lid 14. A filter 9 is arranged above the inner part of the dust box 7. Further behind the filter 9 is a fan 10.
, a fan case 11, and a dust collector motor 12 are arranged.

Thus, by operating the switch 4, the grinder motor 1 and the dust collector motor 12 are operated to generate a flow of air in the flow path shown by the solid line arrow. When grinding is performed using the grindstone 2, large particles such as coarse dust and sparks do not flow to the filter 9, and most of them accumulate on the first dust collection plate 8 or are stored in the dust box 7 due to gravity. . On the other hand, other fine dust flows to the filter 9 and is filtered and collected by the filter 9. The filtered clean air is discharged to the outside of the machine from a discharge port 13 via a fan 10.

If you use the dust collector for a grinder for a long time, a large amount of dust will accumulate on the primary dust collection plate 8, increasing the pressure loss and reducing the suction air volume. Therefore, it is necessary to periodically remove this accumulated dust. be. In this case, as shown in FIG. 3, all you have to do is remove the lid 14 of the primary dust collection section, pull out part of the dust box 7 disposed in the same direction, and scrape out the accumulated dust. Fall within 7.

〔Effect of the invention〕

According to the present invention, it is not necessary to prepare a dust receptacle or treat the accumulated dust with a vacuum cleaner, etc., each time the accumulated dust is treated, as in the past, and the accumulated dust can be easily and efficiently treated at the same time as other dust. can be processed.
