, And has a suction pipe 60.

A metal holding frame 6 is provided in front of the apparatus body 1 in the running direction K, and a driving source, for example, a motor 8 is fixed on the upper plate 7 of the holding frame 6. Holding frame 6
Thrust bearings (or sleeves) 10 and 11
The thrust bearings 10 and 11 hold a plurality of rotating shafts, for example, a rotating shaft 12 and a rotating shaft 13 vertically.

The rotating shaft 12 and the rotating shaft 13 are provided at different positions on a line (not shown) perpendicular to the running direction K of the apparatus main body 1 as shown in FIG.

The rotating shaft 12 and the rotating shaft 13 are vertically movable. Disc-shaped holders 14 and 25 made of metal are attached to lower ends of the rotating shafts 12 and 13, respectively.
A wooden rotating body 15 is attached to a lower surface of the reference numeral 25.

FIG. 4 is a plan view of the rotating body 15 as viewed from below, and FIG. 5 is a side sectional view taken along line RR of FIG.
The rotating body 15 is formed in a plane cross shape in which concave portions 16 and convex portions 17 are alternately formed on the outer periphery. Then, the convex portion 17 is positioned toward the concave portion 16.

On the lower surface of the convex portion 17, a plate-like holder 5 is separately provided.
The brushes 24 are respectively implanted on the lower surface of the holder 50.

The holder 50 is a fixed member, for example, the holder 5
The nut 51 and the screw portion 51 provided on the upper surface of the bracket 0 make it detachable from the rotating body 15. The rotating body 15 is provided with a shaft hole 53, and the screw portion 51 is inserted into the shaft hole 53.

A gear 18 is provided at the upper end of the rotary shaft 12, and the gear 20 of the drive shaft 19 of the motor 8 is engaged with the gear 18.

An annular plate 22 is mounted on the upper part of the holder 14 via a support rod 21. A compression spring 23 wound around the rotary shaft 12 is mounted between the holder 14 and the thrust bearing 10. is there.

A pulley 29 is provided at the upper end of the rotary shaft 13, and a timing belt 31 is hung on the pulley 30 and the pulley 29 of the drive shaft 19.

An annular plate 33 is attached to the upper portion of the holder 25 via a support rod 32, and a compression spring 34 wound around the rotary shaft 13 is mounted between the holder 25 and the thrust bearing 11. is there.

A circuit board (not shown) is mounted on the main body 1 of the apparatus.
It is configured to be able to wirelessly and remotely control the drive and the like. A motor 36 is fixed on the upper plate 7 of the holding frame 6, and a screw shaft (not shown) of the motor 36 is connected to a rod 61 in a sleeve 37.

A lifting frame 38 is provided at the lower end of the rod 61, and the lifting frame 38 is in contact with the lower surfaces of the plates 22 and 33.

The supply pipe 39 of the cleaning liquid tank 4 has reached the vicinity of the holders 14 and 25.

The cleaning device J travels linearly on a cleaning surface (for example, a floor surface, a road surface, etc.) M along the traveling direction K, and the motor 8 is driven by the rotation shaft 12 and the rotation shaft 13. The rotation is transmitted to the body 15, and the rotating body 15 rotates in the opposite directions to each other, and the cleaning surface M is cleaned by the brush 24.

During this cleaning, the cleaning liquid in the cleaning liquid tank 4 is supplied to the cleaning surface M through the supply pipe 39 to enhance the cleaning effect, and the compression springs 23 and 24 are moved by the brushes 24.
To the cleaning surface M to increase the frictional force. Further, the sewage after the washing is vacuum-suctioned by the suction pipe 60 and collected in the sewage collection tank 42.

When the cleaning of the cleaning surface M is completed, the motor 36 is operated to raise the rod 61 as shown in FIG. 4, and the lifting frame 38 is moved through the rotating shafts 12 and 33 via the plates 22 and 33.
The rotating shaft 13 is raised, and the brush 24 moves away from the cleaning surface M.

In this embodiment, when the brush 24 is partially deteriorated (for example, worn or damaged), the brush 24 can be partially replaced by using the holder 50 as a unit. Therefore, the economic burden on the user is reduced, and the components can be used without waste.

(Second Embodiment) FIG. 6 is a plan view showing another configuration example of the rotating body and the holder, and FIG. 7 is a side sectional view of the rotating body of FIG.

Each of the projections 17 of the rotating body 15 has a bearing 5
The disk-shaped holder 55 having the brush 24 is separately provided on the lower surface of the convex portion 17.

The bearing 54 rotatably supports a screw 56, which is screwed into a holder 55. In this embodiment, the holder 55 is freely rotatable with respect to the rotating body 15. Other configurations, operations, and effects are the same as those of the first embodiment.

(Third Embodiment) FIG. 8 is a partial side sectional view of the rotating body 15. A pulley 5 is provided on the upper end of the screw 57 held by the bearing 54 of the rotating body 15.
A belt 6 is attached to a rotating member provided on the rotating body 15, for example, a pulley 60 and a pulley 58 of a motor 59.
Multiplied by one. The above configuration is provided on each of the projections 17, and the other configuration is the same as in the first and second embodiments.

In this embodiment, the holder 55 revolves around the rotation axis of the rotating body 15 and the motor 59 cleans the holder 55 while rotating.

For this reason, the locus of movement of the brush 24 is lengthened, and the cleaning function is improved. Other functions and effects are the same as those of the first embodiment.

The motor 59 may be provided separately for each screw 57, or all the screws 57 may be rotated by a single motor. Further, the motor may be provided on the apparatus main body side.

Brush 24 used in the first to third embodiments
For example, a material obtained by attaching abrasive grains to resin fibers may be used.

Also, different types of brushes may be used for each holder. The brush type is the cleaning characteristics of the brush,
In other words, it means a function, that is, to change the amount of abrasive particles to be attached to the resinous fiber, or to change the thickness, material, and strength of the brush. Then, the cleaning surface M may be properly used depending on the use such as sharpening and shaving.

In this way, the cleaning function of the brush differs for each holder. Therefore, even if the state of the cleaning surface M, for example, dirt, unevenness or the like changes, appropriate cleaning is performed in accordance with the condition. The function can be demonstrated.

Further, the rotating body may have a circular planar shape, and a plurality of holders may be detachably provided on the lower surface along the circumferential direction, and a brush may be embedded in each holder.

Further, the number of concave portions of the convex portions of the rotating body may be set to a number other than the above embodiment. Furthermore, the number of rotating bodies may be one or three or more.

[0040]

As described above, the present invention provides an apparatus main body running on a cleaning surface, a rotating body attached to the apparatus main body and rotatable in the horizontal direction, and provided below the rotating body. And a plurality of holders having brushes, a fixing member for separately attaching and detaching the plurality of holders to and from the rotating body, and a driving source provided on the apparatus main body and rotating the rotating body. Since the types of the brushes are different from each other, the brushes can be partially replaced with the holder as a unit when the brushes are partially deteriorated (for example, worn or damaged). Therefore, the economic burden on the user is reduced, and the components can be used without waste.

Further, since the cleaning function of the brush differs for each holder, even if there is a change in the state of the cleaning surface, for example, dirt, unevenness, etc., an appropriate cleaning function can be exhibited according to the condition. And so on.
