(57) Abstract:

The invention relates to utilities and roads, namely, devices for cleaning of roads from snow and ice formations. The disk carrying levers with salivates attached to the shaft of the drive base of the machine perpendicular to the shaft. The levers are fixed to the disc bottom hinge and divided in the place of attachment in short, facing toward the center of the disc shoulder and a long shoulder, on which are mounted salavatli. When the device is under the action of centrifugal forces produced by the rotation of the shaft, the levers are moved relative to the hinge, closer to the disk surface. Their movement limit lugs are installed in the holes on the disk and are located below it. When this stops interacting with the compression spring arranged on the disk at the top, and hold the levers in position, ensuring effective implementation of scalinatella in snow-ice formation. 1 C.p. f-crystals, 3 ill.

The proposed device relates to the field of utility and road infrastructure, and more precisely to a device for the destruction of the snow and ice formations on the roads and sidewalks, and can be used to clear roads and sidewalks from the ice formations.with. 2022082, CL E 01 H 5/12), comprising a vertical shaft with radially fixed spokes, which means rigidly mounted vertical axes, with the possibility of free rotation installed shearing cones. On the side surface of each cone above its Foundation is made, the teeth of the forming stars.

Asterisks protect the cones from slipping contribute to the concentration of mechanical stresses in the lower part of the face, thus increasing the efficiency of cleavage. However, at the stage of cutting cones in ice formation is hard interaction of the device with the surface to be cleaned, which reduces the reliability of the device and may result in damage to, or destruction of the surface of the pavement. The closest in technical essence is the device (and.with. 1783036, CL E 01 H 5/12) containing pivotally connected with a vertical drive shaft levers, which at the ends are rigidly fixed axis. On the axes set the cone salavatli. The levers are connected by springs with a splined coupling mounted on the lower part of the shaft below the hinges. Due to the spring provides the necessary rigidity with simultaneous flexibility of the device. However, in atomi cones, are in the area of the destroyed material, which, falling into the spring, reduce the effectiveness of their work. When podpisovanie destroyed material, which often occurs at the center of rotation, the system: "the spring, the movable clutch turns into a monolithic snowball. The whole effect from the action of the springs will come to naught. The condition of the springs is determined by the possibility of introducing cones in the surface of the snow-ice formation. Levers to the drive shaft should form a maximum angle. The rise of the springs above the level of the springs slightly stretched, for example, and centrifugal forces are not enough to set the levers perpendicular to the axis of rotation) does not allow the process of cutting. The incision in this case does not occur because of snow-ice formation interacts not front face shearing cones and back. In other words, the springs have no restrictor and with some stretching device becomes inoperative, i.e., spallation snow-ice formation does not occur. The problem is that along with the possibility of effective implementation of scalinatella in snow-ice formation to provide reliable operation at all stages (preseizure, containing vertical drive shaft connected with the shaft and radially mounted levers, mounted on hinges can be rotated in a vertical plane, salavatli mounted on the ends of the levers, and springs further comprises rigidly attached to the shaft and perpendicular to it, the disk, and stops to limit the rotation of the levers installed in the holes on the drive with the possibility of a limited vertical movement. Levers attached to the bottom disk, and each relative to the attachment is divided into two shoulder. Short one shoulder facing toward the center of the disk, as long fixed salavatli. The spring working in compression, are mounted on the disk top with an opportunity to interact with the stops. Salavatli made in the form of plates facing the ground up. Thus the inventive device differs from the prototype in that it further comprises a disk rigidly mounted on the shaft and perpendicular to it, has stops to limit rotation of the levers, the levers attached to the bottom disk and relative to the attachment have two shoulder, short, facing the centre, and long, which is fixed to salavatli, the springs are in compression and are installed on top of the disk with the possibility of the>/P>Two shoulders to pivot the levers mounted on the bottom of the disk, separated from the compression spring mounted on top of the disk, and at the initial moment of cutting short one shoulder rests on the disk under the action of gravity of scalinatella mounted on the long arm, and in the process, due to centrifugal forces and reactive caused by the interaction of scalinatella with snow and ice environment, the long arms of the levers are moved up, the interaction stops. Because dogs are placed in the holes on the drive with the possibility of vertical movement, while interacting with the springs, moving levers stops compress the spring, which turn provide the necessary rigidity and at the same time reliable operation of scalinatella for bumping into snow-ice formation. But vertical movement stops is limited, so the more the depth of the incision, the more hard pressing of scalinatella to snow and ice formations. This increases the efficiency of cleavage, because with increasing cutting layer increases the resistance. Moreover, the increasing efforts of the pressing and cutting is ensured even when a few settled the spring. The implementation of the levers two shoulders and the establishment of the bottom d is the thickness of snow and ice formations. Spring is not in contact with destructible environment and creating the necessary rigidity and malleability of the levers with salivates in the process of all the work, ensure the reliability of the device at all stages. The bottom surface of scalinatella made in the form of plates (edge of the plates), has a small area of the bearing, i.e. the cutting edges due to abrasive particles pavement sharpened, which has a positive impact on the efficiency of cleavage.

In Fig. 1 schematically shows a side view of the device for spallation snow and ice formations in the off position, Fig. 2 - the same, after the introduction of scalinatella in snow-ice formation to the level of the road surface, in Fig. 3 shows a diagram of the installation it stops and mounting of the spring relative to the disk.

The device consists of a motor 1 driving a vertical shaft 2, mounted on the base machine (not shown) by means of a parallelogram suspension, which includes the lever 3, the diagonal lift cylinder 4 and the cylinder 5 of the tilting device. The drive shaft 2 is rigidly connected to the carrier disk 6, the plane of which is perpendicular to the shaft 2. On the lower part of the disk pairs are attached to the brackets 7, between which the insert is ICA lever 9 is divided into two shoulder short and long. Short facing toward the center and is used for secure retention of the lever 8 with scalinatella in a fixed position, and long for the posting of salivates 10 and collaboration with 11 stops.

In an unusable state between the stop 11 and a long lever arm there is a gap (see Fig. 1), and between the lever and the plane of the disc, the angle b. The slot in the lever 8, the bracket 7 and the finger 9 to form a hinged connection. The lugs 11 are installed in the holes on the disk 6 (see Fig. 3) and have a stepped shape. Part of the emphasis is on the bottom of the disk and has a hanger and the upper part is held in the opening drive, has a pressure washer 12. The washer 12 is rigidly connected with the stop 11. The spring 13 is closed by a glass and one side abuts against the cover 15, and the other in a pressure washer (12) while holding the stop 11 so that between his shoulders and the bottom surface of the disk 6, a gap. The upper part of the Cup 14 has a thread on which is screwed the cap 15, and the lower flange to strengthen the disk 6. Salivating 10 has the form of a plate facing the ground up and installed on the axis 16. The axis 16 is rigidly fixed to the lever 8.

The operation of the device is as follows. At the beginning of the work drive shaft 2 Ustari forward movement of the device along arrow a (see Fig. 2) and the rotation shaft 2 of the motor 1, the device is lowered by the hydraulic cylinder 4. The levers 8 under the action of centrifugal force moves in the direction of the disk 6 and rest against the stops 11, between the plane of the disk and the lever is set to a small angle b1(see Fig. 2). Under the sequential interaction of scalinatella 10 with the medium 18 by centrifugal action and reaction forces, the lever 8, moving up, raises the stop 11 and through the bottom of the washer 12 compresses the spring 13. Adjusting the pressure of the spring 13 on the stop 11 and the stroke is carried out by screwing or unscrewing the cap 15 on the glass 14.

The lever and with it salivating in the final position of the incision not held by the spring 13, and the disk 6, which is based on the stop 11. The greater the depth of the incision, the more hard pressing of scalinatella 10 to snow-ice formation 18, which is necessary because with the increase in cutting layer increases the resistance. Increase efforts pressing scalinatella 10 during their movement over the layer of snow-ice formation 18, and the cutting is ensured even when a few settled the spring 13. At the end of cutting a coat hanger stops 11 are in contact with the disk 6, the lever 8 is set relative to the of alaveteli 10 slides on the surface of the road surface, without damaging it, and cutting edge Kalyway snow-ice formation 18. The speed of lowering of the hydraulic cylinder device 4 must be coordinated with the speed of the translational motion of the base of the machine on the arrow And to ensure the effective cutting of scalinatella 10 in the layer formation 18. After introduction of the device driving shaft 2 is mounted a hydraulic cylinder 5 is perpendicular, and the 6 disc parallel to the road surface. When the lugs 11 through a pressure washer by a spring 13 holds the levers 8 parallel to the plane of the disc 6, and salavatli 10, sliding the bottom surface road surface 17, with its cutting edge effectively chop off the snow-ice formation 18. The separation of the arm from the spring allows you to have one attachment point that provides a relatively quick shift levers with other types of scalinatella. Each type of salivates works effectively at a certain thickness of the snow-ice formation. The possibility of using different types of scalinatella can make the device more versatile, at the same time to ensure its effective operation on a different layer thickness of the snow-ice formation. Spring in the proposed device are closed cups Rojstva. The bottom surface of scalinatella has a significantly smaller area of the bearing compared to the prototype, which on one hand reduces the power losses on the other provides a sharpening of the cutting edge. Sharpening is because the road surface includes abrasive particles. Department of the lever by a spring, and the presence of the short arm allows you to set the device levers with different shearing elements. Shearing elements can be performed also in the form of basic profiles or standard cutters, rigidly connected with a lever or rotating bodies with riffles on the periphery, located both on the vertical and horizontal axes.
