JPS58186522A - Electric motor driven smoothing grinder with dust collector - Google Patents

Abstract

PURPOSE:To eliminate the injury of worker's health, by surrounding powdery dust generated at grinding with a dustproof cover mounted to a grinding machine and completely catching the dust through a dust collector and a vacuum cleaner. CONSTITUTION:A disc attaching sand paper is supported with a lock nut to the bottom part of a grinding machine 1 of sanders or the like and rotated by an electric motor. Then a through hole is formed to a part of the peripheral wall of a dustproof cover 3, and one end of a hose 4a is connected to said hole while the other end of this hose 4a is communicated to an air suction side of a blower 5, and an exhaust side of the blower 5 is communicated to the suction port of a dust collector 10 by a hose 4b. Further fine dust not caught even by a porous plate of the collector 10 is discharged from its delivery port to pass through a hose 4c finally seized by a vacuum cleaner 16. In this way, health of the worker can not be injured.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an electric leveling device with a dust collector, which is composed of an electric leveling device and a dust collector, which serves as a scattering protection cover to prevent dust from scattering during leveling work. It is related to.

The city of Jukihito said that it was possible to carry out the level-leveling work, but the dust from the leveling would scatter around the area, causing health problems for workers in the surrounding area and workers in 11. It had become. or,
There were many problems such as having to clean up the dust scattered around the area, and the dust being scattered in the air during cleaning, making it impossible to clean completely.

(1) The invention reduces the scattering of dust during leveling work.
The purpose of this project is to solve the health problems of workers.

B. Did you make a drawing of the invention's electric leveling device with a dust collector? Splash protection 1 with defeat protection hair! ! Attach the i3 with bolts and nuts, attach the hose q that sucks out dust from the side of the blowout protection cover 3, and connect it to the dust collector 10 via the blower S and the hose.

As shown in FIG. 2, this dust collector 10 is provided with opposing windshield walls. This windshield wall is caused by dust sent into the inside of the dust collector by a blower or directly by a large vacuum cleaner.
This is to ensure that there are no rows in A, and to allow dust to fall to the dust receiving box provided in F direction.

The perforated dust adhesion plate /q, which is provided almost in the center of the dust collector 10, allows fine dust that has not fallen into the dust receiving box to adhere thereto, and removes the adhered fine dust by rotating the rotary handle 7 at regular intervals. The dust pan below is a perforated plate for dust to fall into the box.

The ultrafine dust that does not fall into the dust receiving box is connected to a large vacuum cleaner/B via a hose to collect the ultrafine dust.

) This leveler with a dust collector does not scatter dust during leveling work, so it can create an extremely good working environment for the health of workers, and it can be used after leveling work is completed. It has many advantages, including being extremely easy to clean.

Prevents the scattering of dust that sometimes occurs 11? There are some things related to the equipment. Traditionally, when renovating the exterior of a building, such as grinding old paint or polishing the surface of exposed concrete, dust is scattered and causes a nuisance to the neighborhood. There were also health issues for the company's employees. The present invention was made in view of the problems mentioned above.The 11th objective of the present invention is to remove dust generated from a grinding machine very efficiently, and to trap even fine dust to prevent it from scattering to the outside. 11-16 to provide a device. The powder cleaning blowout prevention device according to the preferred embodiment of the present invention will now be described. In the figure, 1 is a grinding machine called a nonder.
Attach 9 sills of lint paper to the grinding machine 1/1/J group.
This grinder 20 is rotated by an electric motor (not shown) and is supported by a II rack 21. A steel-like dustproof/J bar 3 is attached with bolts and knots 1), and the bottom peripheral edge of this dustproof cover 3 has an f-notch shape [, 2 is attached +J].

Armor 6 is placed on one side of 0. One end of a third hose 4C having a capacity of 1.1 +iJ is connected to the discharge 1-1 of the dust 1110, and the other end of this hose is connected to a known vacuum cleaner 16. - When using the equipment listed in F, first grinder 1, air blower 11
5 and the vacuum cleaner 16 are turned on and driven, and then a predetermined floor surface, etc., is ground by grinding Ill. At this time, the dust generated during the grinding work is trapped inside by the dust cover and the brush wiper 2, and then transferred to the blower 5 (from the first hose 4a to the second hose 4b).
The light is sent to the strong III in the collection 1181110. The dust that has entered the inside of the dust collector 10 through the suction 11h) is swept away by the windshield wall (and blown onto the water surface of the aquarium).

0 and the vacuum cleaner 16 completely captures C1. As in the past, the dust is scattered around and harms the health of the workers (l, unfortunately, there are many cases of dust that are relatively common in the history). The dust is first captured by the dust collector, and then only the fine dust that is not captured is captured by the Teikoku Button Remover. The clogging of the dust collector and vacuum cleaner can be relatively slowed down, and the combination of clogging of the dust collector and vacuum cleaner can be prevented by extending the usage time (filter cycle) of both. In this case, since the water tank and the perforated plate are used to remove dust separately, the clogging of the perforated plate is extended, and the usage time (filter cycle) can be extended. 4.
