[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a rotary scraper used for peeling off paint or adhesive layers.

〔従来の技術とその問題点〕[Conventional technology and its problems]

Conventionally, there are two methods for removing paint and adhesive layers applied to floors and walls: scraping them off using a spatula;
There is a method of attaching a circular wire brush to a disc grinder, rotating it, and scraping with the tip of the brush.

ところで、ヘラを用いる方法は、作業が面倒で

By the way, the method of using a spatula is laborious and inefficient, and is difficult to use when removing large areas.
requires a very long time. Furthermore, an adhesive layer that is strongly adhered to a floor surface or the like cannot be sufficiently removed simply by scraping with a spatula.

On the other hand, with the method of rotating a wire brush, the bristles of the brush break quickly, making it difficult to scrub, and at the boundary between the floor and wall, the bent part interferes with the wall or floor and causes damage. There is a drawback. Furthermore, there is a problem in that when a hard adhesive layer or the like is rubbed with force with a brush, the bristles of the brush fall out from the roots, making it impossible to remove them cleanly.

In order to achieve the above object, in this invention, a plurality of blade plates are attached at predetermined intervals in the circumferential direction on one side of a face plate that is fixed to the rotating shaft of the disc grinder, and the tips of the blade plates are attached to the tip of each blade plate. A cutting blade is formed parallel to the face plate, one end of the cutting blade is located forward in the rotation direction of the face plate, and the other end is located further away from the rotation center axis of the face plate than the one end and rearward in the rotation direction, and The other end is made to protrude outward from the outer periphery of the face plate, and the cutting edge is inclined so as to be located on the outside of the attachment edge to the face plate.

Attach the face plate to the disc grinder, press it against the paint or adhesive surface of the blade plate, and rotate. The cutting edge of the blade plate continuously contacts the adhesion surface along the circumferential slope from the part closest to the rotation center axis to the part farther away, scooping up paint and adhesive and scraping it off.

As shown in FIG. 2, the face plate 2 includes two discs 2
A and 2b are formed facing each other, and the rotary shaft 5 of the disc grinder 4 is inserted into a mounting hole 6 provided in the center, and the disc grinder 4 is mounted by tightening a bolt 9 from the front.

As shown in FIG. 1, the disc 2b on the front side of the face plate is provided with a plurality of grooves 8 at predetermined intervals in the circumferential direction, and a blade plate 3 having an arcuate surface in the longitudinal direction.
is installed.

As shown in FIG. 3, this blade plate 3 is made by bending the base into a dogleg shape, fitting the small piece 3a into the groove 8, and caulking the adjacent position with a pin 10. It is held between disks 2a and 2b.

ところで、この小片部3aには、多数の切欠き
7が形成されており、その各々の切欠き7の幅が
少しずつ縮まることによつて、刃板3を均一な円

By the way, a large number of notches 7 are formed in this small piece portion 3a, and by gradually reducing the width of each notch 7, the blade plate 3 can be formed into a uniform arc surface. It's summery.

Note that the small piece portion 3a may be directly fixed onto the disk 2b by pinning or welding.

On the other hand, the bent portion of the blade plate 3 from the small piece portion 3a protrudes forward and outward from the groove 8, and a cutting edge 3b parallel to the attachment edge 3c to the face plate 2 is formed at the tip thereof. The protruding direction of the blade plate 3 is inclined so that the cutting edge 3b is located on the outside with respect to the mounting edge 3c. Therefore, the cutting edge 3 at the tip is placed on the surface to which the paint or adhesive layer is attached.
It digs in from b and scoops up and peels them off, reducing peeling resistance.

また、刃板3が受ける剥離抵抗が、突出方向に
ほぼ一致するので、刃板3の横方向の曲がりが小
さく抑えられて、小片部3a付根からの曲がりや
破損が防止される。
Further, since the peeling resistance that the blade plate 3 receives is substantially the same as the protrusion direction, the bending of the blade plate 3 in the lateral direction is suppressed to a small extent, and bending and damage from the base of the small piece portion 3a are prevented.

Further, as shown in FIG. 1, the blade plate 3 has one end 3d of the cutting blade 3b connected to the other end 3
e, it is positioned forward with respect to the rotational direction indicated by arrow P in the figure, and the end 3e that is rearward in the rotational direction is further away from the rotation center axis of the face plate 2 with respect to one end 3d. It is located.

In this way, when the cutting blade 3b is tilted with respect to the rotation direction, the cutting blade 3b moves from one end 3d close to the rotation center axis to the other end 3e farther away from the surface to which the paint and adhesive layer are attached. Continuous contact cuts through the attached surface as if pulling with a knife. In combination with the above-mentioned axial inclination, the blade plate 3 scoops up the attachment surface from the bottom, and at the same time, the cutting edge 3b
It peels off as if tearing along the slope of the surface.

Furthermore, the peeled paint and adhesive are repelled outward and backward by the inertia of rotation and the inclination of the blade plate 3.

On the other hand, the edge 3e, which is the outer end of the cutting edge 3b, protrudes outward from the outer periphery of the face plate 2 due to the inclination of the blade plate 3b in both directions. Machining can be carried out to every corner without the face plate 2 interfering with the barrier.

In addition, in this embodiment, since the blade plate 3 is formed into an arcuate surface, the contact between the cutting blade 3b and the surface to which the paint or adhesive layer is adhered becomes smoother, and the impact received by the blade plate 3 is reduced. It can be suppressed. In addition, since the arc shape has a bowed shape with a bulge in the center with respect to the peeling direction, a geometrical repulsion force is generated against the force that attempts to deform the cutting edge 3b, and the straight cutting edge Compared to the shape, the overall cutting edge strength is improved. Therefore, it becomes possible to move the surface to which the paint or adhesive layer is attached at a high speed against peeling resistance.

The rotary scraper 1 has the above-mentioned configuration, and when removing deposits, it uses the disk grinder 4.
The cutting blade 3b is attached to the rotating shaft 5 and rotated at high speed.
Move it while pressing it against the surface to which the paint or adhesive layer will be applied. As a result, deposits such as paint can be removed by the cutting blade 3b, which is inclined in both the axial and circumferential directions.
As it is scooped up from the bottom, it is torn and scraped off, and the adhesive layer that is stuck to it is also uprooted.
