Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a cover device of a water drop scattering rod specification which is mounted on a rotating brush of a cleaning device.

(Prior Art) A rotating brush is generally used in a cleaning device for an aircraft, an automobile, a railway vehicle, or the like, and a cover covering the brush is usually attached to this type of rotating brush to prevent water droplets from splashing. ing.

(Problems to be solved by the invention) As a cover to be attached to a conventional rotary brush, there are many fixed type covers in which a portion of the brush facing the surface to be cleaned has a large opening within a range not disturbing the cleaning work. As shown in FIG. 7, during the cleaning operation, a relatively large gap C is formed between the cover A and the surface to be cleaned B, and water droplets such as detergent supplied from the cleaning spray nozzle D on the front surface of the brush are covered with the cover A and the surface to be cleaned B. It will be scattered from the gap C of the cleaning surface B to the outside.

By the way, since the grounding place of a cleaning device equipped with a rotating brush is generally outdoors, it may be unfavorable depending on environmental conditions if the above-mentioned splashed water droplets are carried by the wind during strong winds.

Further, even during non-cleaning, since the brush is always exposed to the atmosphere through the cover opening, the brush is contaminated by dust such as sand dust and the brush material is deteriorated by ultraviolet rays. Such dust contamination of the brush may cause minute scratches on the surface to be cleaned at the time of next use, and may be aesthetically unfavorable when the object to be cleaned dislikes minute scratches such as an aircraft.

Further, depending on the material of the brush, the material may be deteriorated by ultraviolet rays, snow, etc., and the life of the brush may be greatly impaired.

This invention has been made in view of the above-mentioned points, and imparts elasticity to the cover attached to the rotating brush to exert sealing property of splashed water droplets etc. during cleaning work, and to use the brush when not cleaning. An object of the present invention is to provide a cover device for a rotary brush, which is placed in a state of being completely housed in a cover to prevent contamination by dust and deterioration of a brush material.

(Means for Solving the Problems) The gist of the present invention for achieving the above object is to provide a central axis of a rotating brush, which covers the brush and which is expandable and contractible in the brush circumferential direction. A cover composed of side plate portions that cover both sides of the brush is attached, a skirt made of a soft sheet material is extended to the edge of the main body portion facing the cover, and a side skirt is extended to the edge of the cover side plate portion to cover the cover. A cover device for a rotary brush, characterized in that the cover device is connected to an opening / closing drive device.

(Operation) According to the present invention having the above-described configuration, during the cleaning operation, the cover is opened by the opening / closing drive device so as to face the surface to be cleaned, and the skirt edge forming the opening of the cover comes close to the surface to be cleaned. The gap between the surfaces to be cleaned is minimized to improve the sealing performance of splashed water droplets to the outside. At the standby position where the cleaning work is completed and the brush is sufficiently separated from the surface to be cleaned, the cover is closed and the brush is completely stored in the cover.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

This cover 4 forms an appropriate gap around the brush 1,
In addition, the cover main body portions 5 and 6 are configured to be split and expandable in the circumferential direction of the brush 1, and cover side plate portions 8 that are integrally provided on the cover main body portions 5 and 6 and that cover both side surface portions of the brush 1. When mounting the cover 4 on the central shaft 2, the central shaft 2 is rotatably engaged with the side plate portion 8. Cover main part 5,
A skirt 7 made of a soft sheet material is extended to the opposite edge of 6, and the skirt 7 is provided to the opposite edge of the cover side plate portion 8.
A side skirt 9 forming a part of is extended.

However, the above-described divided main body portions 5 and 6 are dimensionally different from each other and are superposed so as to extend and contract, and the skirt 7 has a large number of slits 7a at appropriate depths from its edges. Is provided.

Reference numeral 10 is a support frame that supports the central shaft 2, and is usually connected to a brush support 11 or the like, and the entire brush is fixed or moved. A drive device 12 is mounted on the support frame 10 and opens and closes the cover main parts 5 and 6 to face each other. The drive shaft 13 is connected to a pin 14 fixed to the side plate part 8 via levers 15 and 16. There is.

Incidentally, as the support frame 10, as shown in FIG. 4, a part thereof may be configured to function as the fixed cover 4a.

In the above-mentioned configuration, the apparatus is brought closer to the surface to be cleaned by the cleaning work, and the cover 4 is opened as shown in FIG. 1, that is, the cover main body parts 5 and 6 are rotated in the opening direction by the opening / closing drive device 12. In this state, the edge of the skirt 7 is brought close to the surface to be cleaned and the tip of the brush 1 is applied to the surface to be cleaned.

In this state, when the apparatus is moved while supplying washing water into the cover from a proper place such as the side plate portion 8 of the cover 4, as shown in FIG. 3, the washing by the brush 1 is performed inside the cover 4. , The main body of the cover 5, depending on the condition of the surface to be cleaned,
By rotating 6 the edge of the skirt 7 forming the opening of the cover 4 moves closer to the surface to be cleaned, and a gap is created following the surface angular displacement of the surface to be cleaned. It enhances the sealing property to prevent water droplets from scattering.

When the cleaning work is completed in this way and the brush 1 is not sufficiently cleaned from the surface to be cleaned, the cover main body parts 5 and 6 are rotated in the closing direction by the operation of the opening / closing drive device 12, so that both cover main body parts 5 are rotated. The edges of the skirts 7, 6 are butted against each other under the brush, and the side skirts 9 are also butted, the cover 4 is closed, and the brush 1 is placed inside the cover 4.
