Abstract

This invention relates to machines for cleaving compacted snow and ice from the surface of sidewalks. The purpose of the invention is to increase efficiency by reducing energy intensity and improving the quality of cleaning. The ice-cleaving device contains a platform 1, on which a vibrator 2 and a weigher 3 are mounted. From the bottom of the platform 1, there are five rows of 4, 5, 6, 7 and 8 teeth, which have a wedge shape in cross section and cross section. The tops of the teeth lie in the same plane, inclined to the plane of the platform 1 at an acute angle. Under the action of the vibrator 2, the platform 1 performs vertical and horizontal oscillations. In this case, the teeth are embedded in the ice, producing its destruction. The shape of the teeth contributes to the development of cracks in the layer being destroyed, which reduces energy intensity. 6 Il.

The invention relates to machines for the cleavage of compacted snow and ice from the surface of sidewalks.

The purpose of the invention is to increase efficiency by reducing energy intensity and improving the quality of cleaning.

FIG. 1 shows a device, side view; in fig. 2 is a view A in FIG. in fig. 3 shows a section BB in FIG. 2; Q in FIG. 4 shows a section B-B in FIG. 2; in fig. 5 a section of YYY in FIG. 3; FIG. 6 is a view of D in FIG. one.

The device comprises a flat platform 1, having an oval shape in plan, with a vibrator 2 mounted on it and a load 3 and the teeth of the first 4, second 5, third 6, fourth 7 and fifth 8 2Q transverse ps attached to it from the bottom. Dov. The vibrator 2 is connected to a source of electrical energy and has unbalances 9, mounted on shafts at an angle of 90 ° to each other, to generate a vertical driving force 25 and a shear moment. The vibrator 2 is mounted on the platform 1 in an inclined position.

The tops of the teeth of rows 4-8 are located in the same plane forming 0 with the plane of platform 1 an acute angle, while the teeth indicated themselves have a wedge shape in the plan and in cross section. The front and lower edges of the teeth of rows 4-6 are made sharp with corners “at the top of the wedges 16-18 (FIG. 3).

The front edge of the teeth of row 7 is sharp, and the bottom edge is rounded and with wedge apex angles of 22-25 °. Both edges of the teeth p - d yes 8 are made with rounding and with corners at the top of the wedges 30-35 °. The front edges of all the teeth are inclined to the plane of the platform 1 at an angle smaller than the straight line, and the distance between 45 longitudinal rows is equal to the height of the teeth of the transverse row 8.

The vibrator 2 and the load 3 are mounted for movement along the longitudinal axis with a chain of changing the position of the center of gravity of the device, and the vibrator 2 is also capable of changing the angle of inclination for changing the value of the horizontal component of the driving force and, consequently, the speed of movement of the device. The latter is selected on the basis of approximately known external data.

These conditions are the strength characteristics of ice.

The device works as follows.

The device is installed by the teeth on the ice on the surface to be cleaned and, based on the parameters of the ice, the position of the vibrator 2 and the attachment 3 is established. After a precise choice of the direction of movement, the vibrator 2 and the device turn on, under the teeth of rows 4-8 in the ice layer, under the action of the vertical component of the exciting force begins to move forward under the action of its horizontal component.

In the ice layer, when exposed to teeth of rows 4-8, cracks form and develop, penetrating to the road surface and dissecting the monolith into separate prisms. After all the teeth of rows 4–8 have been sunk, under the action of a shear moment, the chipped ice prisms separate from the road surface.

Priload 3, located in the front part of platform 1, provides a shift of the center of gravity of the device to its front part in order to increase the amplitude of oscillations of teeth of row 8, which contributes to the detachment of ice prisms from the surface of the road surface under shear loads.

When the strip passes to the end of the segment, the device is manually turned and moved in the opposite direction. In addition to cleaning the roads from ice, the proposed device can be used when working in cramped conditions, for example, in yards, in the trough zone of roads.
