Description

The utility model relates to machines designed for chipping snow and ice formations from the surface of the road and sidewalks.

A device for the destruction and cleaning of ice formations [RF patent No. 2606280 25.03.2015, IPC E01H 5/12. Device for destruction and cleaning of ice formations / V.D. Cherepanov, V.M. Volkov, S.V. Cherepanov, L.M. Volkov] consists of a working body, a drum with a folding tool in the form of a set of drummers, which, at their end, are equipped with an inclined end plate forming a bucket. The device provides cleaning of surfaces from any ice formations and snow.

However, the known device has the following disadvantage: the destruction of the ice surface is due to impact, which increases the wear of the working body and increases the likelihood of damage to the road surface.

A device for chipping snow and ice formations is known [RF patent 2022081 10/30/1994, IPC E01N 5/12, Working body for chipping snow and ice formations on roads and sidewalks / A.B. Ermilov, M.N. Rusinov]. The device contains a vertical axis, a sleeve rotating around the vertical axis from the drive shaft, radial spokes are mounted on the sleeve, along which sliders with vertical axes move, on which shearing cones are mounted with the possibility of free rotation, the sliders are connected by springs with a fixed axis through the sleeve with the possibility of adjustment the center of rotation of the cones. This design allows you to destroy snow and ice formations without damaging the road surface.

However, the use of such a device for the destruction of thin layers of ice formations up to 10 mm thick is difficult, since the design does not allow for the proper pressing force of the shearing cones to the road surface.

There is an invention "Vibrating cleaver" for cleaving ice and compressed snow from road surfaces [RF patent 2355845 20.05.2009, IPC E01N 5/12, Vibrating cleaver / I.I. Blekhman, L.A. Weisberg, V.L. Levenharts]. The invention consists of a body, inside of which are placed holders with tools that destroy the coating, and a mechanism for its drive. An oscillating plate with crushing and splitting tools is installed on the springs. The tools drive one or two unbalance vibration exciters with counter-rotating rotors into vertically directed motion.

The disadvantage of this invention is the increased likelihood of damage to the road surface associated with the impact of working tools and the need to adjust the device to a certain thickness of compacted snow or ice. If the thickness of the compacted snow or ice is less than that set in the device, then the contact of the working tool with the road surface will inevitably lead to damage to the road surface.

A device for chipping ice and compacted snow is known [RF patent 2100524 26.12.1991, IPC E01H 5/12. Device for chipping ice and compacted snow / S.V. Pogorelsky, applicant and patent holder S.V. Pogorelsky - 5018185/28; dec. 12/26/1991; pub. December 27, 1997]. The device contains two working bodies located at an angle to each other in a vertical plane. The device allows to destroy ice and snow formations on the surface of roads and sidewalks.

However, the known device has the following disadvantages: the penetration of disk working bodies into the thickness of the compacted snow is carried out only due to the mass of the device, the performance of this design is relatively small due to the small working area.

Of the known technical solutions, the closest in technical essence to the claimed object is the invention [patent CN103835257 (A), IPC E01H5/12. Ground ice and snow sweeper / KONG DEMING; publ. 06/04/2014]. The invention contains a working body - a shaft with a set of ratchet wheels, the shaft is driven from the engine by means of a belt drive. This machine can be used for cleaning snow and ice formations, as well as when cleaning oil sludge from the ground surface.

The destruction of snow and ice formations is carried out due to the penetration of ratchet gears, which are supplied with torque from the engine, the ratchet wheel shaft is equipped with an eccentric, which adds vibration to the cutting process, this is an effective process for breaking snow and ice formations, however, the contact of the teeth of the ratchet wheels and the surface road surface will lead to damage to both the road surface itself and the working body.

The objective of the utility model is the destruction of formations of compacted snow and ice on the surface of roads and sidewalks with a decrease in the likelihood of damage to the road surface and tools.

This achieves the following technical result: the destruction of formations of compacted snow and ice with a low probability of damage to the road surface and tools.

This technical result is achieved by the fact that the device for destroying formations of compacted snow and ice on the surface of roads and sidewalks contains disc knives, the axis of rotation of the disc knives, characterized in that they are installed on the bucket of a front loader, the axis of rotation of the disc knives is pivotally connected to the bucket through the levers and axis of the levers, in order to reduce the likelihood of damage to the road surface, it has two spring racks, which at one end are attached to the bucket with the help of scarves, and at the other end are attached to the axis of rotation of the disc knives.

The utility model is illustrated in FIG. 1, which shows the design of the proposed device: a) the position of the blade when the disc knives are in the working position, b) the position of the blade for snow removal.

The figure shows 1 - bucket (front loader), 2 - axes of levers, 3 - levers, 4 - axis of rotation of disk knives, 5 - disk knife, 6 - spring rack, 7 - scarves, 8 - compacted snow (ice), 9 - pavement.

The main difference of this utility model is that the disc blades 5 penetrate into the thickness of compacted snow (ice) 8 under the action of the mass of the bucket 1. The possibility of rotating the disc blades 5 around its axis 4 and its attachment to the bucket 1 due to the levers 3 and spring struts 6 reduces the likelihood of damage to the road surface 9.

This principle of destruction of compacted snow and ice reduces the likelihood of destruction of the road surface, due to the absence of shock loads.
