RU2321705C1 - Device to loosen and remove particles of soil, snow and ice from road pavements - Google Patents

Abstract

FIELD: mechanical engineering; earth-moving machinery.

SUBSTANCE: invention relates to working members of earth-moving machines used simultaneously for loosening and removing higher strength particles, for instance, soil, show and ice, from road pavements, street roads, etc. Proposed device contains ripper-pick secured on traction frame, for instance, by means of articulated joint. Said ripper-pick can be lowered and lifted by means of hydraulic cylinders. Motor grader blade on slewing circle is attached also to traction frame. Moreover, device contains bulldozer blade mounted in front on standard hitch. Ripper-pick is located between bulldozer and motor grader blades.

EFFECT: enlarged operating capabilities of earth moving machine.

Description

The invention relates to the working bodies of machines for earthmoving, used for simultaneous loosening and moving soil, snow and ice, for example bulldozers and graders used for cleaning city streets, road surfaces.

There are known designs of earthmoving machines in which a ripper-picker and a blade are installed on one machine. At the same time, the cultivator-picker is used to soften the soil, snow and ice of increased strength. The blade is used to remove loose soil, snow and ice from pavements, pavements.

So, for grading snow and ice, motor graders with a motor grader blade, a bulldozer blade and a cultivator-ripper were widely used. [Beletsky B.F. Building machinery and equipment: A reference guide. - Rostov n / a: Phoenix, 2002. - p. 133].

The reason that impedes the achievement of the required technical result is that well-known graders can only perform work operations one at a time. In this case, the hydraulic system controls each of the working bodies through its actuator.

Closest to the claimed solution is a grader DZ-143, containing a grader blade, a bulldozer blade and a cultivator-picker. [Beletsky B.F. Building machinery and equipment: A reference guide. - Rostov n / a: Phoenix, 2002. - p. 132].

The disadvantage of this machine is that the cultivator-picker is located behind the grader and bulldozer dumps. However, the possibility of alternate functioning is not provided.

The problem to which the claimed technical solution is directed is to create a machine capable of destroying the upper durable layers of soil, snow and ice by means of a cultivator-pickaxe and at the same time moving them using a grader blade.

When carrying out the invention, the task is solved by expanding the functionality of the digging machine.

The specified technical result is achieved by the fact that the device for loosening and removing soil, snow and ice from road surfaces contains working bodies in the form of a bulldozer blade on a hitch, a traction frame and a grader blade mounted on it on a turntable, as well as a ripper-picker, which is connected with traction frame via articulation and lifting cylinders. The peculiarity is that the cultivator-picker is located between the bulldozer blade and the grader blade, which is mounted on the traction frame to enable simultaneous operation of the bulldozer blade, grader blade and the cultivator-picker.

The location of the working bodies of the device allows you to exclude the cultivator from the process as a separate machine.

The drawing shows a device for loosening and removing soil, snow and ice from road surfaces, General view.

The device is mounted on a basic machine, contains a traction frame and working bodies: a cultivator-picker, a grader blade on a turntable, a bulldozer blade on a hitch.

The pick-up cultivator 1 is fixed on the traction frame 2, for example, by means of an articulated joint. The cultivator-picker 1 has two hydraulic cylinders 3 to provide the possibility of lowering and raising.

A grader blade 4 is attached to the traction frame 2 on a turntable.

The device comprises a bulldozer blade 5 located in front of the hitch hydraulic cylinders.

The device operates as follows:

The bulldozer blade 5 is lowered into the working position by the hydraulic cylinders of the hitch for cleaning the pavement of the upper less durable layer, for example, a layer of soil, snow and ice. To soften the layer of soil, snow and ice remaining after the work of the dozer blade 5, a ripper-picker 1 is used. Using hydraulic cylinders 3, the ripper-picker 1 is lowered into the working position and softens a more dense layer of soil, snow and ice. Using a grader blade 4 on a turntable, loosened soil, snow or ice are transported, for example, to the place of loading. This increases the degree of versatility of the device by combining the functions of several machines in one.

Mounting a grader blade on a turntable and a pick-cultivator on one traction frame allows you to loosen and simultaneously clean the road surface.

To reduce the load on the traction frame 2, it is possible to equip the ripper-picker with a vibrator (not shown), which will reduce the resistance force of the particles with increased tensile strength. Thus, the mass of the ripper can be reduced.
