RU64485U1 - BRUSH CLEANER BRUSH - Google Patents

Abstract

The utility model relates to the field of tools for cleaning road surfaces, namely, brushes mounted on sweepers.

The technical result of the proposed utility model is to improve the alignment during the installation of brush discs.

The brush of the sweeper consists of a drive shaft 1, on which brush disks 2 are mounted, oriented relative to the shaft 1 by means of protrusions 3.

At the ends 4 of the disk 2 there are hollows 5 displaced relative to each other.

The depressions 5 of the adjacent disks 2 form closed cavities 6.

These closed cavities 6 can be made in the form of bee honeycombs, or in the form of rectangles, or in the form of rhombs.

Beams 7 of the pile are fixed around the circumference of the disk 2, which form a broken line along the disk profile.

Along the drive shaft 1, rods 8 are rigidly mounted, interacting with the protrusions 3 made on the hubs of the disks 2.

In addition, on each disk 2 an additional protrusion 9 is made.

The locking protrusion 9 interacts with the rods 8, but on the opposite side of the protrusion 3. (4 zp, 7 ill.)

Description

The utility model relates to the field of tools for cleaning road surfaces, namely, brushes mounted on sweepers.

Known brushes, which are disks mounted on a drive shaft, around which tufts of tufts are fixed (see ed. Certificate of the USSR No. 1313420 according to class A46B 3/08 of April 13, 1984 BI No. 20 for 1987)

Known brush sweeper, consisting of mounted on the drive shaft drives, around the circumference of which are fixed tufts of pile. At the ends of the disks there are hollows displaced relative to each other and forming closed cavities with the hollows of adjacent disks, which can be in the form of honeycombs or in the form of rectangles, or in the form of rhombs. (See certificate for utility model of the Russian Federation No. 9367 according to class A46B 3/08 dated July 6, 1998 BI No. 3 for 1999)

A brush of a sweeper is also known, consisting of installed by means of connecting devices made in the form of protrusions on the hubs of disks interacting with rods rigidly fixed along the drive shaft, and tufts of pile are fixed around the circumference of the disks.

The rods are fixed at an angle of 120 ° relative to each other. (See RF patent of utility model No. 39793 according to class A46B 3/08 of April 19, 2004; BI No. 23 of 2004)

A disadvantage of the known brush sweeper is the lack of alignment of the brush disks mounted on the shaft and the resulting imbalance.

The technical result of the proposed utility model is to improve the alignment during the installation of brush discs. The proposed brush, consisting of installed by means of connecting devices made in the form of protrusions on the hubs of disks interacting with rods rigidly installed along the drive shaft, additionally has a locking protrusion interacting with the rods, but from the opposite side. These essential features are in a causal relationship with the technical result.

Figure 6 is a General view of the brush with disks having cavities in the form of rhombuses.

The brush of the sweeper consists of a drive shaft 1, on which brush disks 2 are mounted, oriented relative to the shaft 1 by means of protrusions 3.

At the ends 4 of the disk 2 there are hollows 5 displaced relative to each other.

The depressions 5 of the adjacent disks 2 form closed cavities 6.

These closed cavities 6 can be made in the form of bee honeycombs, or in the form of rectangles, or in the form of rhombs.

Beams 7 of the pile are fixed around the circumference of the disk 2, which form a broken line along the disk profile.

Along the drive shaft 1, rods 8 are rigidly mounted, interacting with the protrusions 3 made on the hubs of the disks 2.

In addition, on each disk 2 an additional protrusion 9 is made.

The locking protrusion 9 interacts with the rods 8, but on the opposite side of the protrusion 3.

The brush works as follows.

The shaft 1 of the sweeper drops to the cleaned surface until the tufts 7 of the pile come into contact with it. Then the shaft 1 is driven into rotation and the material to be removed (dust, dirt, snow, etc.) is given not only rotational movement but also radial displacement due to the broken line of the arrangement of the tufts 7 of the pile.

Harvested material enters the hopper of a street sweeper (not shown in the drawing)

Moreover, in the process, the harvested material falling into the closed cavity 6 of the disks 2, working as closed buckets also enters the hopper.

The different shape of the closed cavities 6 allows you to optimize the cleaning of various types of harvested material.

Using the proposed utility model allows to increase the efficiency of the sweeper brush by improving the alignment of the brush discs and reducing their imbalance.
