Description

Portable grinder having a dust collecting structure {Portable electric grinder having a Dust Collecting Structure}

The present invention relates to a hand grinder having a dust collecting structure, and more specifically, a dust collecting structure for forming dust collecting means at a rotating part of the hand grinder to immediately collect dust generated during work to greatly improve work efficiency and working environment. It relates to a hand grinder having.

In general, the hand grinder is a kind of grinding tool used for the surface treatment and processing of wood, stone and metal materials.

That is, for example, a hand grinder for polishing a surface of various structures such as a ship and various building materials, such as interior materials and exterior materials, rotates at a high speed while a polishing head and an abrasive plate are fixed to a drive shaft, thereby polishing the surface of a workpiece such as metal or stone. It was supposed to be.

Typically, the grinder has a disk-shaped abrasive plate, and the surface of the abrasive plate is subjected to a polishing process such as sand paper, thereby polishing the surface of the workpiece by rotating at a high speed in close contact with the surface of the workpiece.

The grinder includes a drive unit formed at a predetermined position of the body, a polishing head installed on the rotation shaft of the drive unit, an abrasive plate provided on the bottom surface of the polishing head, and a fixing unit interconnecting the polishing head and the abrasive plate to the rotation shaft. Is made large.

Therefore, the grinder polishes the surface of workpieces such as ships and other structures and buildings using friction by high-speed rotation.

The conventional grinder structured as described above simply has a structure in which the polishing member rotates at high speed on the surface of the object to be polished to polish the surface. Therefore, a large amount of dust is generated during the machining operation, which makes it difficult to work. there was.

That is, a large amount of dust and stone are generated when the surface of the object and the polishing member are rotated at a high speed to generate a large amount of dust and stone. There was a dislocation that caused.

In addition, it is impossible to precisely grind the worker's view during the grinding process, and additional equipment such as a mask or goggles is required to protect the worker from dust, and even if the accessory equipment is worn, the worker's health is prevented from the dust. There was not enough to protect.

In addition, in the case of indoor interior construction, for example, the workplace is contaminated with dust, which causes inconvenience to perform dust removal work after work, and also causes pollution of the indoor environment.

The present invention has been made in view of the above problems, the object of which is to form a dust collecting means on the rotary part of the hand grinder to immediately collect the dust generated during the work to greatly improve the work efficiency, improve the working environment to more comfortable conditions It is to provide a hand grinder having a dust collecting structure to enable.

Features of the present invention for achieving the above object, the head 10 is provided with a drive means is mounted on the inside, a rotating shaft 12 for transmitting the rotational force of the drive means, and the head ( In the hand grinder composed of a grinding member 13 for rotating the shaft while being fixed to the rotary shaft 12 of 11), the cover 20 is formed with a discharge port 20a for suctioning and discharging dust to one side The cover 22 is coupled to the head 11, the suction fan 21 is rotatably coupled to the inside of the cover 20 by the rotation shaft 12, and the cover 20 has a suction hole 22a formed in the center of the cover 22. ) Is coupled to the polishing member 13, and a plurality of suction holes 13a are formed, and the polishing member 13 is spaced apart from the cover 22 to be rotatably coupled by the rotation shaft 12. Dust collection guide 23 surrounding the polishing member 13 is characterized in that coupled to the cover 20 Having a binary structure that would be achieved by a hand grinder.

In the present invention as described above, since the dust generated during the polishing process of the surface of various structures such as ships and various building materials, exterior materials, etc. can be sucked out and discharged to the outside through the dust collecting means at the same time as the working process, It is possible to improve work convenience and improve work convenience, and to perform work while processing dust generated during work quickly, thereby improving work productivity and thereby improving product reliability. It is a very useful invention

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 4, the present invention is the head 10 is provided with a body 10 is equipped with a drive means on the inside, a rotating shaft 12 for transmitting the rotational force of the drive means, and the head It consists of an abrasive member 13 which is fixed to the rotary shaft 12 of 11 and rotates together while polishing the workpiece.

Of course, the hand grinder having the above-described configuration is a known technical idea.

However, the most important feature in the present invention is to combine the dust collecting means to the head 11 to inhale and discharge the dust generated during the polishing process to the outside at the same time as the work process to improve the work convenience.

That is, the head 20 is coupled to the cover 20 is formed with a discharge port (20a) for suction and discharge dust to the outside on one side.

The suction fan 21 is coupled to the inside of the cover 20 so as to be rotated by the rotation shaft 12.

The cover 20 is coupled to the cover 22 having a suction hole (22a) in the center.

In the polishing member 13, a suction hole 13a for sucking dust is formed.

The polishing member 13 is rotated by the rotating shaft 12 to be spaced apart from the cover 22 at a slight interval.

A dust collecting guide 23 is formed around the polishing member 13 to prevent dust from scattering to the outside and is coupled to the cover 20.

The dust collection guide 23 is preferably configured as a corrugated pipe that can be adjusted up and down according to the height of the polishing member 13 and can withstand a heat source well.

Reference numeral 30 is a suction means, 31 is a connection hose.

Referring to the effects of the present invention made of the above-described configuration is as follows.

First, when performing a polishing operation using the hand grinder according to the present invention, the outlet 20a and the suction means 30 of the cover 20 are connected to the connection hose 31 and the polishing operation is performed.

When the hand grinder and the suction means 30 according to the present invention are operated and the polishing operation is performed, the polishing member 13 is rotated by the rotating shaft 12 to polish various surfaces such as ships and various structures such as ships, interior and exterior materials. will be.

Dust generated during polishing is generated by the suction fan 21 of the cover 20 as the suction shaft 21 is rotated by the rotary shaft 12 to generate suction force, so that the suction hole 13a of the polishing member 13, the polishing member 13, and the cover. Dust is sucked into the interspace of the 22 and is sucked into the cover 20 through the suction hole 22a of the cover 22.

The dust sucked into the inside of the cover 20 is discharged to the outlet 20a of the cover 20 by the suction force of the suction means 30 is sucked into the sound absorbing means through the connection hose 31.

In addition, dust is sucked into the cover 20 in the dust collection guide 23 by the dust collection guide 23 surrounding the polishing member 13, rather than scattering out of the dust collection guide 23.

Thus, dust generated during the polishing operation is sucked by the dust collecting means composed of the cover 20, the suction fan 21, the cover 22 and the dust collection guide 23 to improve the work convenience, improve the work productivity, The working environment can be improved to a more pleasant condition.

Although the preferred embodiments of the present invention have been shown and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments without departing from the spirit of the present invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.
