Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dust collection device suitable for implementation in a rotary brush type cleaning machine that cleans a floor or road surface with a rotating brush while running.

[Prior Art] Conventional rotary brush cleaning machines use the rotation of a rotating brush to sweep and collect dust on the floor or road surface into a bucket, and the collected dust is collected by removing the bucket from the cart or by was carried to a dust disposal site (garbage dump) while still attached to a trolley and disposed of.

[Problem that the invention attempts to solve]

However, in the bucket used in the conventional rotary brush cleaning machine mentioned above, the wide dust sweep port directly serves as the dust disposal port, so when disposing of the collected dust, the bucket is used. After lifting the whole thing and removing it from the trolley, you have to turn the sweep opening downward to let the dust fall out, which makes the work surprisingly troublesome and requires a lot of strength, making it difficult for women and children to remove the dust. There was a problem that people with weak powers could not easily dispose of it.

In addition, if the collected dust is fine dust with a light specific gravity, when the dust is disposed of through the sweeping opening by turning the bucket upside down, the dust will fly up and cause secondary pollution, which is a sanitary issue. There are problems such as being undesirable or polluting the surrounding area.
Further, as a result of contaminating the surrounding area, the dust must be disposed of in a bucket or the cleaning machine itself must be transported directly to a dust treatment plant, which is a hassle.

Therefore, the technical problem of the present invention is to enable anyone to easily and quickly dispose of dust collected in a bucket on the spot without causing secondary pollution.

[Means for solving problems]

The measures taken in the present invention to solve the above technical problems are as follows.

In a rotary brush cleaning machine configured such that a rotating brush rotates and sweeps dust into a bucket when the machine is run, (1) the bucket for collecting dust is configured to be removable from the cart; Arms are provided on both left and right sides of the cart to support support shafts protruding from both sides of the removed bucket cart and to support the entire bucket cart so that it can fall and rotate freely.

(2) A dust discharge port is provided at the tip of the bucket, and a discharge lid is hinged to this discharge port, which opens when the bucket is turned over so that the discharge port faces downward.

(3) A hook shall be provided on the bucket to which a dust collection bag can be hung and attached to the discharge port.

[Effect]

The elements (1) and (2) above each operate as follows.

The element (1) above is achieved by removing the bucket from which the dust has been collected from the box attached to the cart, and attaching support shafts protruding from both sides of the box to arms projecting upward from both sides of the cart so that they can rotate freely. By supporting it, it is possible to extremely easily and smoothly overturn and rotate the bucket, which is necessary for disposing of the collected dust, with a small amount of force.

The reason for (2) above is that when the left and right support shafts are supported by the left and right arms and the bucket is turned over so that the outlet is facing downward, the outlet cover opens and the outlet opens automatically. , allowing dust to be quickly discharged from this outlet.

The factor (3) above is that when the bucket is turned over, a dust collection bag is hung on the outlet using a hook, and the dust is scattered or thrown around. All collected dust can be discharged into the inside of the dust collection bag without causing any secondary pollution, and the collected dust can be disposed of in a sanitary manner without causing secondary pollution.
However, it can be done easily.

As described above, the above-mentioned technical problem can be solved by the means consisting of the above-mentioned elements (1), (2), and (3), and the problems of the above-mentioned conventional technology can be solved. .

(Omitted) A rotating brush 7 is attached which always rotates clockwise in the drawing to clean the floor or road surface. Furthermore, in FIGS. 1 and 2, 8 is a side brush that rotates in conjunction with the rotating brush 7,
This has the effect of scraping the dust accumulated on the floor or the corner of the road surface onto the running surface of the rotating brush 7.

Next, 10 is a bucket for collecting dust that is detachably attached to the above-mentioned trolley 3, and the tip surface 10
This bucket 10, which is formed into a substantially hopper-like shape with the a side tapered, has the tip surface 10a.
A dust exhaust port 10b is opened at the part, and a large dust sweep port 10c (see FIG. 4) is opened at the rear surface to sweep the dust as the rotating brush 7 rotates. Entrance 1
0c fits into the opening of the box 6 described above.

Further, 11 is a discharge port 10b of the bucket 10.
A discharge lid that opens and closes, and this discharge lid 11 always closes the discharge port 10b to prevent dust leakage. However, when the bucket 10 is turned over so that the discharge port 10b faces downward as shown in Fig. 4, , is hinged to the tip end surface 10a of the bucket bag 10 by a spring-loaded hinge 12 so as to be opened by its own weight and the weight of dust to open the discharge port 10b.

Next, reference numerals 13 and 13 indicate support shafts protruding from both the left and right sides of the bucket cart 10, and 14 and 14 indicate arms for supporting the bucket cart which are provided upwardly projecting from both the left and right sides of the cart 3. At the upper ends of the arms 14, 14, as shown in FIGS. 2 to 4, there are support shafts 13, 1 for the bucket 10 which has been removed from the cart 3 and lifted.
