In the work of removing), and the work of removing the latance (such as slag and slag that has hardened due to the rise of impurities) before the concrete splicing, the wire brush, It was extremely troublesome because it was manually peeled off using a tool such as a glass and then swept away with a broom. For this reason, recently, a machine equipped with a rotary grinding body composed of a cutter blade group that rotates at a high speed by driving a motor has been transformed into a mechanical work for pressing the surface to be ground of concrete.

Workers are forced to wear dust-proof masks and eyeglasses so that they do not inhale dust and cause diseases such as pneumoconiosis, which is troublesome and hinders work efficiency. This is the same even if the work site is a structure on the ground (buildings, railways, highways, bridges, etc.), but in particular, the laitance removal work that is indispensable in concrete placing work on the deep foundation of a transmission line tower (large tower) Then, the place is diameter 3 ~
Since it is carried out in a deep foundation pile of 4 m, more dust than necessary is needed, so a conventional concrete grinder without a dust suction device cannot handle it. Moreover, this deep foundation is troublesome because many reinforcing bars are finely planted, so that the concrete grinder shown in FIG. 9 (see, for example, Japanese Utility Model Publication No. 54-18008) is conventionally known. Like,
In the type in which the rotary grinding body a and the drive motor b are arranged at the front and rear positions (planar) of the machine body c, and the fixed gripping handles d and e are arranged at the front and rear of the machine body, the width is inevitably wide and the narrow arrangement is narrowed. It is difficult to insert between the streaks, and the dust f of the scraped concrete is scattered and polluted to the surrounding (front in the drawing) because it is not equipped with a dust collector.

なる周囲に粉塵を漂わすことがない。As described above, the rotary grinding body in which a plurality of spindles for arranging the cutter blades are arranged around the opposing flywheels is provided in the lower portion of the vertical casing, and a part of the cutter blades is provided. The bearing is arranged so that it protrudes from the opening, and this rotary shaft is linked to the cutter motor arranged on the upper part of the vertical housing with a gear transmission mechanism and is collected in the suction port of the vertical housing. Since a dust hose is connected and the whole body (machine) has a vertically long compact structure, the grip part of the stick-shaped operation handle protruding from the lower part of the vertical housing is held, and the vertical housing is a latance layer generated on the concrete surface. Place it on the top surface of. In this case, since the main body has a narrow width structure in which the rotary grinding body and the motor are installed in a vertical casing that has two upper and lower stages, the main body can be easily placed on the concrete surface between the narrow reinforcing bars and has a predetermined length. Since the operator's handle (stick) is held, it is possible to work in a standing posture. Here, if the cutter motor and a dust collector separately arranged are driven, the laitance on the concrete surface is scraped by the cutting operation of the cutter blade of the flywheel that rotates in high speed in contact with the concrete surface. Moreover, the concrete dust scattered here is forcibly sucked to the dust collector side by the suction action of the dust collection hose facing the suction port of the vertical casing that houses the cutter blade group (rotary grinding body), and the outside of the casing Does not drift dust.

It is also possible to raise the foldable handle on the side of the machine and squeeze the fixed handle on the rear side to perform the grinding work only with the main body of the grinder. Of course, even here, the scraped dust is sucked up by the dust collecting hose side.

面とか天井面等の普通の処理面にも対応できる。As described above, the concrete grinding machine with a dust collector of the present invention accommodates the rotary grinding body in which a part of the cutter blade is exposed from the lower end opening in the vertical casing having the cutter motor arranged on the upper part thereof. In addition, a dust collection hose connected to the dust collector is connected to the suction port provided in the vertical housing via a pipe-shaped operation handle that is projecting on the housing, or the dust collection hose is directly connected to the suction port, A part of the dust hose is detachably guided to the vertical housing with a protruding rod-shaped operation handle, so when performing grinding work on the laitance of a concrete surface, you can hold the operation handle and operate it easily while standing. Can be ground with a cutter blade. In this case, since the vertical casing and the motor for driving the rotary grinding body are arranged in two stages, upper and lower, and the total load is applied to the cutter blade, it is possible to perform light grinding in combination with pressing of the rod-shaped operating handle, and The concrete surface can be easily moved. Further, the entire machine body has a vertically elongated and narrow width grinding machine in which the motor section and the rotary grinding body section are vertically arranged in two stages, and can be easily inserted even between narrow reinforcing bars.
Of course, since the grinder has a compact structure, it can also be used for ordinary processing surfaces such as concrete wall surfaces and ceiling surfaces.

がる。Moreover, the present invention forcibly removes the grinding dust, which is the most problematic problem in concrete grinding, by the suction action of the dust collecting hose of the dust collector facing the suction port of the vertical housing, so that the surroundings are not polluted. Needless to say, there is no risk that workers will inhale dust. This allows the user to work without wearing a dust mask or the like, which in turn leads to improved work efficiency.

の効果を有する。For work in narrow places such as corners, a detachable type handle is used. If necessary, the handle is detached from the vertical casing and the folded handle is grasped. Grinding work can be done easily by pressing. Here again, a dust collecting hose is connected to the vertical housing, which has the effect of forcibly removing dust.
