Description

[Detailed Description of the Invention] The present invention is intended to provide a vibrationless cleaning machine having a novel configuration.

Conventionally, this type of device is as follows.

Traditionally, during concrete floor construction work, the concrete used for this work spilled onto the floor surface.
This will harden. As it is impossible to treat the surface as it is, a time-consuming process is being carried out to scrape it off.

The present invention is intended to fully solve this problem, and details of its embodiments will be described below with reference to the drawings.

1 is the vibration-free cleaning machine of the present invention.

The configuration is such that a front rectangular rear frame 3 is erected at the rear end of a planar rectangular base plate 2 provided with moving wheels 2A on the lower surface, and a planar rectangular frame 3 is erected on the rear frame 3 in a state parallel to the base plate 2. An upper frame 4 is provided in series, a handle 5 is made to stand up on the upper part of the rear frame 3, and a chisel guard plate 6 having a rectangular plane is provided in series in the horizontal direction on the front edge of the board 2. In the frame F consisting of the substrate 2 and the upper frame 4,
The main body 7A of the electric hammer 7 is located between, and
The main body 7A of the electric hammer 7, which is supported so that the tip of the hammer 7 only for cleaning 7B is almost in contact with the floor surface, is vertically stretched between the rear part of the main body 7A and the upper frame 4 of the frame F. A horizontal rubber 8 is stretched between the tip of the main body 7A and the rear frame 3 of the frame F when the electric hammer 7 is pulled in the direction of the upper frame 4. At 9, while the electric hammer 7 is being pulled in the direction of the rear frame 3, an electric hammer 10 is applied to the diagonal rubber 10 stretched between the rear part of the main body 7A and the guard plate 6 only in the frame F. The hammer 7 is supported in a state where it is pulled in the direction of action of the hammer 7B only for cleaning.

7A1 is a lead wire.

8A, 9A, 10A are metal fittings for pulling the rubbers 8, 9, 10 in the direction of the frame F, and are composed of bolts having a ring at the tip, and nuts 8B, 9B, 10
By rotating B, the tension state of the rubber can be adjusted.

11 is a light installed as necessary; 12
is a side rest rubber band attached as required.

Furthermore, the relationship between the chisel guard plate 6 and chisel 7B is such that the chisel guard plate 6 and chisel 7B penetrate through the planar square opening 6A formed in the chisel guard plate 6 and protrude to the front.

Next, how to use the proposed product will be explained along with its effects.

Install it on the concrete floor surface that you want to treat,
When the electric hammer is activated, the chisel 7B moves diagonally downward as shown by arrows A and B.

As a result, the hardened concrete spilled onto the floor surface can be scraped off by a tapping action.

During such work, the electric hammer is supported by rubber in a tensioned state from multiple directions, so vibrations are not transmitted to the worker, making the work easier and preventing the negative effects of vibration on the body. can.

In the present invention, two electric hammers are installed as shown in FIG. 2, but it is also possible to install one electric hammer or two or more electric hammers.

Furthermore, if the wheels on the guard plate side, that is, the front wheels, are swivel wheels, it is of course easier to operate.
