Abstract

The invention relates to machines for cleaning roads from snow-ice formations. The aim of the invention is to increase efficiency by reducing energy consumption. The working unit for breaking the ice is the drive shaft 1, on which pairs of discs 2 are installed. Springs 3 are mounted between the disks 2 of each pair. The impactors 13 are mounted on the rods 9 with the possibility of being moved in the radial direction. Between each pair of disks 2 are placed slides 5 associated with levers 17. When the shaft 1 rotates, the impactors 13 deflect by centrifugal force and strike blows on the ice-snow formations, destroying them. To increase the energy of the strikers 13 in increased ice thickness, the levers 17 move the sliders 5 and bring the disks 2 of each pair together. The rods 9 move and increase the rotational radius of the strikers 13. I Cp f-ly, 4 ill. S (l

WITH

The invention relates to machines for cleaning roads from snow-ice formations.

The aim of the invention is to increase efficiency by reducing energy consumption.

Figure 1 schematically shows the proposed working body, side view; figure 2 is a view of And figure 1; on fig.Z - section bb in figure 2; figure 4 - section bb In figure 2.

The working member contains a drive shaft 1 with a horizontal axis of rotation. On the shaft 1, a pair of disks 2 are mounted on a sliding slide 1, with a landing that can be moved along it and between the disks 2 of each pair there are springs 3 of compression. On shaft 1 in

the splines 4 are arranged with the possibility of spring 20 springs 3, and the discs 2 each displace along the shaft 1 are slider 5 with supports 6 fixed to the slide 5 with bolts 7. On the peripheral part of the discs 2 are hinged by one condom by means of kinematic pairs 8 and 9 the other ends of which, using hinges 10, are housings 11 with axes 12 drummers 13. On the latter, there are removable bolts 14. The drummers 13 have oval grooves in which axes 12 are placed, which allows the drummers 13 to move in the radial direction. At the ends of the shaft 1, bushings 15 are fitted with support bearings 16 associated with movement levers 17 abutting on sliders 5 and rolling bearings 18. Depending on the width of the removed strip of ice, several pairs of disks 2 can be mounted on the shaft 1 so that the pullers 14 cross the entire strip to be cleaned. In order to better balance the loads on the shaft 1, a pair of disks 2 are offset one relative to another by an angle determined by the number of impactors 13 installed on one pair of disks 2.

The working body works as follows.

After installing the working body to its original position, i.e. at a certain height from the road surface, the rotation of the shaft I is turned on and at the same time a basic machine (not shown) is set in motion, on which the tool is mounted. When rotating shaft 1 with disks 2 under the action of the centrifugal force of freedom25

Do a pair to each other. The rods 9 move closer and the distance of the browsers 14 from the longitudinal axis of the shaft 1 increases. Thus, the kinetic energy of the cleavers 14 increases, which makes it possible to develop a large amount of ice without increasing the speed of rotation of the shaft 1 and the speed of movement of the base machine. This allows more economical use and distribution of drive energy.

In the case of a decrease in the thickness of the ice layer being stained, the levers 17 return to their original position, the pairs of disks 2 by the springs 3 are moved apart, the rotation radius of the cleavers 14 decreases, and at the same time the energy of the scalgoi decreases.

1. A working body for breaking ice and compacted snow on road surfaces, containing a drive shaft with a horizontal axis of rotation, disks mounted on the shaft, on the peripheral part of which there are articulated impactors, characterized in that, in order to increase efficiency by reducing energy consumption, it is equipped with tongs, each of which is pivotally attached at one end to the disk, with the disks mounted in pairs, with sliders located on the shaft between the pairs of disks with the possibility of movement along the shaft together with the dis kami, and compression springs mounted on 55 but the hanging drummers 13 acquire the necessary kinetic energy and, when they encounter ice, the cleavers 14 destroy it. When rockers meet 4 with materials whose strength characteristics are higher than ice, road pavement, sewer manholes, etc. drummers 13 not only rotate around axis 12, but also move along it in the radial direction, thereby copying the profile of the road surface. In the case of increasing the thickness of the layer ice bearings 16 act on the levers 17 and move the slide blocks 5 with the supports 6 along the slots 4, thereby moving the disks 2 of each pair, respectively, which compress Do a pair to each other. The rods 9 move closer and the distance of the browsers 14 from the longitudinal axis of the shaft 1 increases. Thus, the kinetic energy of the cleavers 14 increases, which makes it possible to develop a large amount of ice without increasing the speed of rotation of the shaft 1 and the speed of movement of the base machine. This allows more economical use and distribution of drive energy.
