[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sweeper which can be used as a cleaning vehicle for a golf course, a park, a road or the like or a grass collecting vehicle.

[0002]

2. Description of the Related Art A conventional sweeper of this type is shown in FIGS.
Will be described. In the figure, 1 is a traveling vehicle, 2 is a sealed tank mounted on a chassis 1a of the traveling vehicle 1, and has an upper inlet 2a and an outlet (not shown) with a sealed lid. Reference numeral 3 denotes a rotary brush located below the chassis 1a and having a width that is the full width of the chassis 1a. The rotating brush 3 is rotatably fitted to the horizontal shaft 4 and acts as a scraping member for scraping up dust and the like. Reference numeral 5 denotes a cover which covers the rotary brush 3 and forms a dust collecting chamber 5a, which is installed on the horizontal shaft 4. Reference numeral 6 denotes a circulating air device arranged between the closed tank 2 and the rotating brush 3, and an outward passage portion 6a in which an inlet 601 is opened in the upper center of the cover 5 and an outlet 602 communicates with an inlet 2a of the closed tank 2, A fan chamber 6b provided in an intermediate portion of the outward path portion 6a and an inlet 603 are opened in the central portion near the outlet 602 of the outward path portion 6a and an outlet 604 is provided.
Is composed of a return path portion 6c opening to the center of the upper portion of the cover 5 and a fan 6d provided in the fan chamber 6b. 7
Is a rotating shaft of the fan 6d, and is driven by the engine 8 by transmission of the band 9. Reference numeral 10 denotes an iron plate fan casing that forms the fan chamber 6b, and is installed on the chassis 1a. The fan 6d is composed of a rotating disk 11 having a boss portion 11a and a plurality of blade plates 12 each of which is inserted and joined into a plurality of cut grooves 11b arranged around the rotating disk 11. ing. The rotating brush 3 may be driven by the engine 8 or a separate engine.

Next, the operation will be described. When the fan 6d is driven, the circulating air that circulates from the dust collecting chamber 5a to the closed tank 2 through the outward path 6a and from the closed tank 2 to the dust collecting chamber 5a through the return path 6c (indicated by the arrow in FIG. 3). (Indicated by) occurs. Therefore, the dust and the like picked up by the driven rotating brush 3 rides on this circulating wind and is accommodated in the closed tank 2. For a detailed description of the operation and device of this circulating air, see, for example, Japanese Examined Patent Publication No. 63-1024.
No. 1 publication.

[0004]

In the conventional sweeper as described above, when the rotary brush 3 scrapes grass turf, fine sand is simultaneously scraped together with the grass dust. At the time of renewal, the sand is scraped up together with the turf by the rotating brush 3, so that the spirally wound body plate 10a of the iron plate fan casing 10 is worn by the sand, and thus cracks are produced, thereby fulfilling the function of the fan 6d. There was a problem that it could not be done.

The present invention has been made in order to solve such a problem, and an object thereof is to obtain a sweeper capable of remarkably reducing the wear of the fan casing due to sand to prevent the generation of cracks and maintaining the fan function for a long time. .

[0006]

In order to achieve the above object, a sweeper according to the present invention is configured such that a portion of a fan casing of a spirally wound body plate that is most exposed to dust or the like is detachable, and the duster is detachable. The cushioning material is adhered to the portion where the most is hit.

[0007]

In the present invention, the abrasion of the spirally wound body plate of the fan casing due to the sand is eliminated by the cushioning material, the cushioning material can be easily attached and replaced, and the shock caused by the centrifugal force of the sand is also produced by the cushioning material. Will be alleviated.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. 1 is a cross-sectional view showing a fan casing, and FIG. 2 is an exploded perspective view showing FIG. 1. The same or corresponding parts as those of the conventional one are designated by the same reference numerals, and the description thereof will be omitted. In the figure, 13a to 13e are fan casings 1.
Openings formed in 0 spiral body plate 10a, 14a to 14
Reference numeral e denotes a divided body plate that closes each of the openings 13a to 13e from the outside, and is detachably attached to the outer peripheral surface of the spirally wound body plate 10a by a bolt nut 15. 16
Reference numerals a to 16e denote cushioning materials that are attached to the inner surfaces of the respective divided body plates 14a to 14e by means such as lining and baking, and are made of rubber sheets having a size and a thickness that fit into the respective openings 13a to 13e. . In addition, 1 in the figure
Reference numeral 7 denotes a detachable side plate formed on the fan casing 10, which allows the fan 6d to be inserted and removed.

When the spiral wound body plate 10a of the fan casing 10 is provided with the cushioning materials 16a to 16e in this manner,
The sand hits the cushioning materials 16a to 16e, and the sand is the fan 6 among others.
Since the cushioning material 16a located at the deadline portion of d and the cushioning material 16e located at the final curved portion of the swirl winding having the fastest flow velocity hit most, the spiral wound body plate 10a of the iron plate fan casing 10 is worn by sand, There are no cracks. In addition, the shock absorbing materials 16a to 16e reduce the impact of the centrifugal force of sand. Moreover, each cushioning material 16a-
16e can be easily attached and replaced by attaching / detaching the divided body plates 14a to 14e.

[0010]

As described above, according to this invention, the wear of the fan casing due to sand is remarkably reduced, cracks are eliminated, and the fan function can be maintained for a long time.
