Description

The invention relates to a sweeper for the winter and summer maintenance of urban areas.

The purpose of the invention is to increase production efficiency by changing the direction of the flow of the thrown snow.

Figure 1 shows the working body of the sweeper, side view;

figure 2 is the same, top view; on

fig.Z - the same, rear view.

The working body of the sweeper contains a cylindrical brush 2-f mounted on a lifting frame 1 and mounted perpendicular to the longitudinal axis of the machine. Frame 1 using levers 3 and 4 parallelogram suspension and hydraulic cylinder 5 is connected to Koppus 6. Inside the circle of rotation of the pile of the brush 2, there are elements 7 of the reflector, which are made of circular cross-section with the front ends bent at an angle to the horizontal plane (Fig. 2). 8, directed in the direction of snow throwing with a brush along arrow A. With respect to the axis of rotation 2, the front ends 8 are located in the indicated projection at an acute angle of 90 ° - ft. The rear ends of the reflector elements 7 are each located in the radial plane of rotation of the brush 2, which coincides with the plane of movement of the machine, and are mounted with the possibility of rotation around their longitudinal axis on the beam 9 installed behind the brush 2 parallel to the axis of its rotation. The inflection points B of the reflector elements 7, separating their front ends 8, are located under the axis of rotation of the brush 2. The rear ends of the reflector elements 7 are equipped with cranks 10 and fingers 11, which are connected by means of a movable rod 12 parallel to the axis of rotation of the brush 2, between themselves and with the control hydraulic cylinder 13 mounted on the transverse plate 14. The beam 9 and the plate 14 are mounted with the help of brushes 15 on the lifting frame 1 with the possibility of vertical fixed movement relative to the frame 1 by shifting the holes on the pins Tille 16. A bent front end of the cranks 8 and 10 of each reflector element are arranged in one plane. The angle in this plane between the element 7 of the reflector and its transducer

hertz - the true angle between the element 7 of the reflector and its front end 8;

v is the angle of inclination of the front end 8 of the element 7 of the reflector relative to the horizon in the radial plane of rotation of the brush 2 (Fig. 1); V is the angle of inclination of the element 7 of the reflector relative to the horizon in the radial plane of rotation of the brush 2 (Fig. 1); ft is the acute angle between the element 7 of the reflector and its front end 8 in the horizontal plane, equal to the angle of rejection of contaminants relative to the direction of movement of the machine along arrow G. (figure 2);

Oi is the angle of rotation of the crank 10 relative to the neutral average position (Fig. 3), corresponding to the angle A from; brushing snow and dirt 2.

When sweeping is cylindrical, the brush 2 interacts with the road surface 17 within the contact zone B (figure 2) and throws snow or pollution along the arrow G oriented at an angle C relative to the horizon (figure 1).

The working body of the sweeper produces road surface cleaning as follows.

The pile of the rotating cylindrical brush 2 is divided by the reflector elements 7 located in the radial planes. In the process of rotating the brush 2 after passing the vertical position corresponding to the B point of the bend of the element 7, the pile interacts with the bent front end 8 of each element 7 and bends axially at an angle of 90 ° - | 3 relative to the axis of rotation of the brush. At the same time, the pile bars are peeled off from the road surface 17 and snow or dirt is thrown off in the direction of arrow A (Fig. 2). As the bristles of the brush 2 wear out, the reflector is adjusted by periodically shifting the holes 16 in

brushes 15 relative to the lifting frame pins 1.
