Description

The invention relates to devices for removing unwanted substances from roads and similar surfaces, in particular to devices for clearing snow from curbs [E01H1/00, E01H5/00, E01H8/00, E01H1/003, E01H1/105, E01H5/06 , E01H8/02].

Known from the prior art is a MOUNTED SNOW BLOWER [US4074448(A), publ.: 02.21.1978], containing a vertically extending hinge, sections of blades on both sides, and the plow can be located in the form of a protruding V-shaped, recessed cup-shaped or at an angle in any direction or sideways across the width of the vehicle.

The main disadvantage of this technical solution is the high labor intensity of clearing snow from the surfaces of curbs (curbs), which may lead to damage to the surfaces of curbs (curbs).

Known in the prior art is a DRIVEWAY SNOW Blower [US4754562 (A), publ.: 07/05/1988], containing a snow blower assembly for various vehicles, while the plow blade is fixed at the desired angle by inserting one pin through a plurality of aligned holes , formed in the stabilizing rod, tongue and support bracket.

The main disadvantage of this technical solution is the high labor intensity of clearing snow from the surfaces of curbs.

Known from the prior art, adopted as a prototype, is a SNOW CLEARING MACHINE [RU2015115738(A), publ.: November 20, 2016], containing a vehicle and a passive actuator for dumping snow, with the scrapers located under the vehicle with a ledge to shift (dump) snow in one direction.

The main technical problem of the prototype is the inability to clear snow from the surfaces of curbs (curbs), since the plow blades are located under the vehicle.

The objective of the invention is to eliminate the disadvantages of analogues and the prototype.

The technical result of the invention is to reduce labor and time costs when carrying out road work to remove snow from curbs (curbs) and maintain their integrity, as well as increase the versatility of the device.

The specified technical result is achieved due to the fact that the device for clearing snow from curbs, containing a main scraper and an additional means for clearing snow, is characterized in that the main scraper is fixed on the frame, and the additional means for clearing snow is removable and can be moved in a vertical plane, in this case, it is mounted on a movable block, the drive of which is hydraulic.

In a particular case, a scraper with a layer of material that ensures the integrity of the surface being cleaned is used as an additional means of clearing snow.

In a particular case, a brush is used as an additional means of clearing snow, the rotation drive of which is hydraulic.

Brief description of the drawings.

In fig. 1 is a front view of a snow clearing device;

In fig. 2 shows a top view of a snow clearing device;

In fig. Figure 3 shows a three-dimensional rear view of a movable scraper.

The figures indicate:

Implementation of the invention.

The claimed design of the device for clearing snow (see Fig. 1,2) contains a frame 1 on which the frame levers 2 are mounted, interconnected by a jumper 3, a double ear 4 for attaching to the front eye 5 the hydraulic cylinder for raising and lowering the device 6 for clearing snow , the main scraper 7, the movable block 8, as well as the hydraulic cylinder 9 for extending the movable block 8. In this case, the frame 1 on its rear side in the lower part has an internal cavity 10 for moving the guide rod 11 of the movable block 8 in it, and the arms of the frame 2 are mounted to frame 1 at an angle that ensures the snow shifts in the required direction when clearing it.

The main scraper 7 is mounted in the middle part of the frame 1, while in its lower part, replaceable knives 13 are installed using, for example, riveted joints 12, made of a material with increased wear resistance, and on its reverse side they are installed, for example, welded to the frame 1 and the rear part main scraper 7 stiffeners 14.

The movable block 8 (see Fig. 1 - 3) contains a base 15 on which an additional means of clearing snow 16 (in a particular case - a scraper) is mounted, connected to a slider 17, the upper part of which is connected using a removable pin to the front eye 18 a hydraulic cylinder for raising and lowering 19 of an additional means of snow removal 16, mounted on the outside of the restrictive box 20 and connected to it with its lower part. In this case, the working surface of the additional snow cleaning device (scraper) 16 has a layer 21 of material that ensures the integrity of the curbs when clearing snow. In a particular case, the working surface of the additional snow clearing agent (scraper) 16 is rubberized.

A guide rod 11 is mounted from the bottom of the base 15, located in the internal cavity 10 of the frame 1, while the dimensions of the internal cavity 10 and the guide rod 11 are designed to ensure unhindered movement of the guide rod 11 in the internal cavity 10, and a fastener 22 is mounted on the upper part of the base for connecting the movable block 8 with the hydraulic cylinder 9 for its extension.

To adjust the angle of inclination of the additional means of cleaning snow (scraper) 16, if necessary, holes 23 are made in its rear part, using which, by inserting two fingers into them, the scraper 16 is connected to the slider 17 at the required angle of inclination.

The snow clearing device is used as follows.

The structure of the claimed device for clearing snow, installed as an attachment on equipment, for example, on a tractor with hydraulic equipment, is located at the edge of the curbs on the surface to be cleared in the direction of travel. In this case, the additional snow cleaning device (scraper) 16 with the slider 17 of the movable block 8 is raised to a height slightly higher than the height of the curb (curb), and the main scraper 7 is installed at its edge.

After that, by combining two holes 23 in the movable block with two fingers, the required angle of inclination of the additional snow clearing device 16 is set. Then, using the drive of the extension 9 hydraulic cylinders and the lowering lift 19, the movable block 8 is extended to the distance required for clearing curbs, and the additional cleaning device 16 snow falls on the surface of the curbs.

When the equipment moves forward, thanks to the tilt of the frame 1, snow is shifted from the curbs and from the surface to be cleared by a distance depending on the width of the main scraper 7, and a snow ridge is formed, which is subsequently removed using municipal equipment.

If necessary, as an additional means of clearing snow 16, a brush is used, the rotation of which is carried out using a hydraulic drive (not shown in the figures), thereby increasing the versatility of the device for clearing snow.

Clearing snow from curbs (curbs) and shifting it for further removal is carried out in one pass of equipment with the declared design of a device for clearing snow, thereby achieving a reduction in labor and time costs when carrying out road work to remove snow from curbs (curbs), and thanks to the layering of working surfaces of an additional means of snow cleaning (scraper) 16 - the integrity of the curbs (borders) is maintained.
