Abstract

FIELD: machine building.

SUBSTANCE: proposed working tool has ice-breaking tool fitted on shaft and provided with set of hammers. Said ice-breaking tool comprises two extreme drive discs fitted on opposite shaft extensions, one rigidly fitted on the shaft and another one being coupled with coupling and engaged with shaft by means of key, and working discs arranged regularly between drive discs with hammers rigidly secured thereto and made up of cutters. Every working disc is fitted on the shaft and provided with holes made regularly on disc edges to allow passage for cables via spacer springs to connect all working discs that are fastened in extreme drive discs.

Description

The invention relates to devices for cleaning roads in the winter, in particular to the working bodies of machines used for loosening and chipping snow-ice formations on road surfaces of streets, highways, sidewalks.

It is known that the working body of the machine for removing compacted snow in the form of a round comb knife is known. (Operation of special vehicles for the maintenance and repair of city roads / V.I. Balovnev, G.L. Karaban, I.A. Zasov and others; Edited by L.L. Afanasyev. - M.: Transport, 1983. - S.100.)

The disadvantage of this working body is the rigid fastening of the knives, which does not allow to bend around the irregularities of the surface being cleaned. This leads to damage to the surface being cleaned, the knives themselves or to under-cleaning of the surface.

A device for cleaving snow-ice formations on road surfaces, containing an ice cleaver, which is made in the form of a frame horizontally mounted on a vehicle boom, on which bearing bearings are located with a shaft mounted in them and with a set of disc-shaped interchangeable drums fixed to it, each which consists of a sleeve mounted on the said shaft, rigidly connected by means of a disk partition with a short cylindrical shell, the outer side of which contains at least its two rows of steel cutters and are contained on the inner side movably mounted loads which impinge on said cylindrical shell replaceable disklike drum (RU 94582, IPC E01N 5/12, publ. 27.05.2010) during vehicle movement.

The disadvantage is the rigid fastening of the cutters, which leads to increased wear of the cutters, their breakage, damage to the surface being cleaned or to under-cleaning the surface. In addition, the design is complex, which makes it difficult to repair the cleaver and replace wear parts.

A known working body of an ice chipping machine (adopted as a prototype) having a cleaving tool mounted on a shaft made up of a disk with a hub and holes uniformly along the edge of the disk, a set of percussion instruments connected to the disk by articulated axes (RU 2265104, IPC E01H 5 / 12, published on November 27, 2005).

A disadvantage of the known working body is the articulation of the strikers, since the articulated joints quickly fail, in addition, during operation, the articulated joints become clogged with snow, which reduces the efficiency of this design.

The objective of the invention is to improve the quality of cleaning road surfaces from snow-ice formations, as well as increasing the durability and reliability of the working body of the machine for breaking ice, making it easier to mount it on a vehicle.

The problem is solved by the working body of the ice chipping machine having a cleaving tool mounted on a shaft with a set of hammers. Unlike the prototype, the shearing tool contains two extreme leading disks mounted on opposite ends of the shaft, one of which is rigidly fixed to the shaft, and the second is fastened to the coupling half and connected to the shaft by means of dowels, working disks evenly located between the leading disks with hard disks fixed to them impactors made in the form of cutters, and each working disk is freely mounted on the shaft through a Central hole, the diameter of which exceeds the diameter of the shaft, and has holes that are evenly spaced disk paradise, through which ropes are passed through the spacer springs, connecting all working disks and fixed in the extreme leading disks.

According to the invention, the second drive disc is fastened to the coupling half by means of a bolted connection.

The design features of the working body allow the working disks along with the cutters fixed on them during operation to vibrate freely, oscillate on the shaft in horizontal and vertical planes. The entire surface of the working body, as it were, "wriggles", providing high quality cleaning.

The analysis of the prior art made it possible to establish that the applicant has not found an analogue characterized by features identical to those of the claimed invention. In addition, it is not known and not obvious from the prior art that as a result of the proposed distinguishing features, an improvement in the quality of cleaning road surfaces from snow-ice formations is achieved, as well as an increase in the durability and reliability of the working body of the ice chipping machine.

The invention is illustrated in the drawing, which shows the inventive working body of the machine for chipping ice.

The working body of the ice chipping machine contains a shaft 1, two extreme leading disks 2 and 3 mounted on opposite ends of the shaft, the disk 2 being rigidly fixed to the shaft, and the disk 3 fastened with a half-coupling 4 bolts (not shown), working equally spaced between the leading disks discs 5 with drummers rigidly fixed on them, made in the form of cutters 6. Each working disk is freely mounted on the shaft through a central hole (not shown), the diameter of which exceeds the diameter of the shaft. Holes (not shown) are evenly spaced along the edge of each working disk, through which ropes 8 are fastened through spacer springs 7, fixed in the extreme leading disks 2 and 3. The disk 3 is connected to shaft 1 by a key 9.

The operation of the device is as follows.

The working body of the ice chipping machine is installed as suspension equipment on utility road machines or tractors instead of standard brush equipment. When the working body of the machine rotates due to the shock movements of the front cutting edge of the cutters 6 on the ice, it is chipped. The disks 5, freely “hanging” on the shaft 1, are fixed on the sides by springs 7, in the center by the shaft 1. The whole structure is “wriggled” during operation, as a result of which the movement of the disks 5 with cutters 6 occurs both in vertical and horizontal planes, while the end part of the cutter slides along the road surface of the coating without damaging it. The design flexibility is provided by ropes 8 and spacer springs 7. The impact of the cutter 6 on ice is transmitted to the tensioned ropes 8 and to the springs 7, causing the cutters to vibrate, which increases the area of the road surface being cleaned and improves the quality. Running into obstacles (bulge, bumps), due to the flexibility of the design, the surface of the working body goes around bumps, which avoids damage and fracture of the incisors.

Due to the cushioning of the flexible ropes and the increased mobility of the disks, the service life of the cutters increases. The working body is easily mounted on any machines designed for cleaning roads, which allows you to remove ice and compacted snow in hard-to-reach areas (in yards, alleys). The working body of the ice chipping machine is easily repaired, since all parts can be replaced.

Thus, the claimed invention allows to improve the quality of cleaning road surfaces from snow-ice formations, as well as to increase the durability and reliability of the working body of the machine for breaking ice, to facilitate its mounting on a vehicle.
