SU1259999A1 - Cylindrical brush - Google Patents

Description

The invention relates to means for cleaning surfaces, namely cylindrical brushes mounted on sweepers.

The purpose of the invention is to improve the quality of surface cleaning.

FIG. 1 depicts the proposed cylindrical brush; in fig. 2 - the same, side view; in fig. Figures 3 and 4 show the layouts of the pads on the scan of the cylindrical surface of the brush, variants.

The cylindrical brush contains discs 2 installed at opposite ends of the drive shaft 1, brackets 3 arranged along their circumference and spring-loaded holders 4 of a diode 5 with brush elements 6 parallel to the shaft axis 1 and brackets 3 mounted parallel to the shaft axis 1, - The holder 4 has a pair of rocker arms 7, a ball connected with it some ends, the other congres of which are pivotally connected to the bracket 3 and located perpendicular to the axis of the shaft 1.

The pads 5 are connected to their holders 4 by means of a hinge 8. The disks 2 have radially arranged grooves 9 and the brackets 3 are installed in these pairs to compensate for the wear of the brush elements 6. A spring 10 is installed between each holder 4 and the bracket 3 brush elements are placed around the circumference of the brush in rows, with each subsequent row being offset by SNAP 2599992

the previous one, and the pads installed, at the ends of the brush, are placed at an angle to the shaft axis.

On the brackets 3 fixed hinges 5 levers 11.

The brush works as follows.

When the brush rotates, the brush elements 6 tend to disperse under the action of centrifugal force in the radial direction, overcoming the resistance of the spring 10 and the elastic material of the brush element interacting with the surface to be cleaned. The presence of rocker arms 7 provides

15 moving the holder 4 with the pads 5 relative to the fixed joints 11 without turning in the plane of rotation, copying the surface to be cleaned in the working limits of the spring Y.

20 Hinge 8 allows the block 5 with the brush elements 6 to rotate in its plane and copy the surface along the length of each brush element 6 regardless of the movement

25 springs 10.

Installed at an angle, the pads with the brush elements cast scoops in the direction of the pads located in the center part, in order to avoid material being knocked out

sides of the brush.

The device allows a solid elastic brush element, regardless of the others, to copy the irregularities of the surface being cleaned, improving the quality of cleaning and increasing the cleaning efficiency.
