Abstract

Use: relates to machines for cleaning urban roads. SUMMARY OF THE INVENTION: Two oval brushes are mounted on the frame of the machine, mounted on gears 5 made in the form of closed-loop rails. Brushes have a shape identical to the contour of the rails. The brushes are made from, gear KO / fec-OBanbH e wheels 5 are engaged with b round wheels 7, which are kinematically connected to each other through other round wheels, one of which is connected to the shaft 9 of the drive of the machine. The axis of rotation 10 of the oval wheels 5 is installed in grooves made along their large diameters. Depending on the direction of movement of the drive shaft 9, the MuguT brush grows oppositely or counter-directionally, along a complex trajectory that increases the width of the treated strip 3 sludge.

WITH

The invention relates to machines for cleaning urban areas, in particular roads, pavements, squares, and the like.

The famous sweeper-collector KO-309 (Production of machines for cleaning urban areas: Reference manual. M .: Stroyizdat, 1986. p. 17-20), containing two chute brushes with vertical axes of rotation, pneumatic vacuum pick-up, including a brush with a horizontal axis of rotation.

The disadvantage of this machine is the small width of the surface to be treated, as well as poor-quality cleaning, due to the fact that the brushes, rotating around their axes, scatter debris, so a small part of it falls on the cylindrical brush. In addition, due to the long length of the cylindrical brush, the pneumatic vacuum unit pulls out debris unevenly across the entire width of the cleaning strip.

Also known sub-cleaning-on machine Foreign sweepers-cleaning machines, no. 2, M .: (TsNIITEstroymash, 1985, p. 879), comprising two brushes with vertical axes associated with the drive and pneumatic vacuum pick-up located on the chassis for movement on the chassis. The disadvantage of this is low efficiency, but low efficiency of the treated surface. „„

The purpose of the present invention is to increase the cleaning efficiency by increasing the width of the surface to be treated. For this purpose, in a sweeping machine that contains two brushes with vertical axes of rotation associated with the drive and pneumatic vacuum picker along the movement of the chassis, they are made oval

I ate with

Waters of rotation of each brush are formed from meshing-on-one with each other outer sides of the round m dump wheel, the last of which is made in the appropriate shape of a bristle, with the axis of rotation of the round holas connected kinematically, and one for them 2p1e1. Each of the oval wheels is mounted in a groove that is made along its large diameter.

Sharp execution allows the brushes to be informed of both opposing and opposing complex movements between co-movements, which increases the cleaning efficiency, increases the width of the treated surface and increases the brush service life.

On F ig. 1 shows the proposed sub-metal cleaning machine, side view; pas figs. 2 is the same section A-A in FIG. one; in fig. 3 shows the setting of 5-B in FIG. 2

On the chassis 1 of the machine there are two brushes 2 with vertical axes of rotation, a drive of the brushes, a pneumatic vacuum pick-up, a screwdriver. A horizontal axis of rotation and a pneumatic vacuum installation (partially shown).

The brushes 2 and gears 5 are mounted on movable protective covers G and are oval in plan. Gears 5 are engaged with round gears; IMH wheels 7, which are kinematically connected to each other through 1 round gear teeth / scr 8.

One of the gear wheels 8 is connected via an axis 9 with a machine drive (not shown). The axis 50 of the gear wheels are rigidly fixed on the housing 11, Suspended on the chassis 1 on the shock absorbers 12, and installed in the grooves 13. oval gear wheels 5 made along large diameters,

On the housing 11 is fixed in an arc-shaped plan, a shower 14 for supplying water and ps 15 shaped P-shaped, the side walls of which are made in the form of a comb.

Sweeping machine works as follows. When the shaft shaft 9 is rotated, the gear wheels 8, 7, and 5 are rotated. As the gear wheels 5 and brushes 2 are mounted on protective covers

6, the latter are brought into complex motion: linear - both brushes move in the same direction; arcuate - brushes make a counter arcuate movement,

Depending on the direction of rotation of the drive shaft 9, the brushes may rotate in opposite or opposite directions. The latter can be applied if necessary to clean the passage.

When counter-rotating the brushes, they act on the debris on the road surface, move it inward (arc-shaped movement), then, in a straight-line movement, feed the scoop to the cylindrical brush 3, which supplies it to the vacuum unit.

In the arcuate movement of the brush 2, it passes through the combs of the combs 15 and is freed from debris stuck in the fibers of the brushes.

Due to the fact that the brushes receive complex movements of variable direction, the cleaning efficiency is increased,

the width of the surface to be treated increases. During the work of the brush, with an arc-like movement, it goes beyond the limits of the dimensions of the machine, which makes it possible to remove debris from curbs and walls.
