RU2990U1 - Dump of the bulldozer - Google Patents

Abstract

The blade of the bulldozer, including sliding sections with knives and guides and a hydraulic section control, characterized in that the sliding sections are located in front on the blade and pivotally attached to it.

Description

The utility model relates to the field of road construction machinery, namely, earthmoving machines of the Yuldozero type.

Known dozer blade, including a retractable middle section with guides and a drive extension section (copyright certificate N 366252 E 02F 3/76)

The disadvantage of this design is that this design cannot work on soils with rocky inclusions, low productivity, the inability to work on frozen soils, the complexity of the design.

E of the closest analogue (a. With N 759663 cells, IPC E 02F 3/76) retractable sections are included in the bulldozer blade with knives located on the sides of the blade and pivotally connected to the blade in the middle part.

But the above construction has several disadvantages. there are great efforts in the x-cylinders of the sliding sections and large loads on the hinges, the inability to work on frozen soils and soils with rocky inclusions.

Utility Model Disclosure

The task of creating the proposed utility model was to extend the service life through the use of removable sections, the ability to work in frozen soils with inclusions, increase the productivity of the bulldozer.

This is achieved by the fact that in the blade of the bulldozer, including sliding sections with knives and guides and a hydraulic control section, the sliding sections are located in front on the blade and pivotally attached to it.

Brief Description of the Drawings

The utility model is illustrated by drawings, which depicts a basic machine with a blade and movable sections, front view, on Fikh-. 2 blade with movable sections, rear view.

The best option for implementing the resulting model

The blade 1 of the bulldozer 2 is attached to the base machine. It includes retractable sections 3 mounted in front of the blade and attached to the front end of finger 4, the second end of which is connected to the rod 5, hingedly mounted in the absorber: 6. The middle part of each rod 5 is connected to the rods of the hydraulic cylinder 7, the body of which is rigidly attached to atE : and lu.

Technical field

State of the art

The bulldozer blade works as follows: when the blade 1 is deepened using the hydraulic cylinder 7, the distance between the sections 3 changes due to the displacement of the hydraulic cylinder rods 7, while the section 3 loosens the soil layer 1 in front and below the blade 1, the inclusions are turned out of the soil. When used on frozen soils, the plows of the retractable sections 3 loosen the layer under and in front of the blade 1, facilitating the development of the soil. As wear, the sliding sections 3 can be replaced by removing the finger 4 from the rod and attaching a new plow to it.

Industrial applicability A utility model may be road construction, development

applied on preparatory work; frozen ground with inclusions.
