The invention relates to self-propelled machines, mainly to small-sized tractors with working equipment for non-industrial construction designed for carrying out excavating, transportation of bulk cargo to the destination, the exact mechanized unloading.

In the technique known use of tractors with work equipment designed for excavation and loading, such as road-building machines "international" (USA), containing reverse shovel and front loading equipment [1] . A common shortcoming of models 3820 And, 3600 And 2400 In and the other is the complexity of the design due to equipment tractors working equipment to separate technological operations excavation and Petelino narrows their scope.

It is also known that the operation of the self-loading and transportation of soil are special machines, scrapers, such as road-building machines company "international" models 444, 442, 431, and others. However, the principle of soil samples typical scraper unacceptable when performing work associated with excavation, fence materials from the mound and a number of other operations.

In domestic engineering industry has a similar design of wheeled tractors with excavation equipment, front loading equipment, as well as scrapers.

For example, nepolnomernyj hydraulic excavator on the basis of wheel tractors [2], scrapers DZ-13 (D-392), DZ-67 [3].

These road-building machines have all the above-mentioned disadvantages.

Closest to the invention is a technical solution that contains a self-propelled chassis, a body, a hinge mounted on the chassis frame can be rotated in a vertical plane by a hydraulic cylinder, lifting jib, mounted to rotate in a vertical plane by a hydraulic cylinder, lifting body, made in the form of a bucket mounted to rotate in Weert who has all of the above-mentioned disadvantages.

The aim of the invention is to improve the operational capabilities of the vehicle devices bootstrap and sambursky.

This objective is achieved in that in the vehicle containing the self-propelled chassis, a body, a hinge mounted on the chassis frame can be rotated in a vertical plane by a hydraulic cylinder, lifting jib, mounted to rotate in a vertical plane by a hydraulic cylinder, lifting body, made in the form of a bucket, mounted to rotate in a vertical plane by a hydraulic cylinder, and a hydraulic control cylinders, the chassis frame is made of two semiframes, pivoted between a vertical hinge can be rotated in a horizontal plane, and provided with a casing and a body mounted on the first and second Palermo, with the possibility of turning in a horizontal plane by a hydraulic cylinder, which is equipped with lifting boom with the handle and lifting body, hinged to the ends of the boom and dipper with rotations in the vertical plane hidrocilindrii, and the hydraulic control cylinders contains d is with cavities cylinders rotate arrows, arm, hauling and unloading, and the second section two-section pump communicated through the appropriate distributors with cavities cylinder turning, body, and drain.

In contrast to the process and prototype vehicle expands the scope of technology operations include excavation or fence from the mound of soil or other cargo, its loading dump hopper, transportation to the destination, measured (due to different angles of inclination of the body) the exact sapovirus. In addition, in the cycle of self-loading provided independent combination of on-time operations through the use of combined hydraulic control cylinders made with two independent hydraulic circuits from two sections of the pump.

In Fig. 1 shows a vehicle; Fig. 2 - hydraulic control cylinders.

Self-propelled chassis 1 of the vehicle includes two semi-frames 2 and 3, connected by a hinge 4 to ensure rotation of one semi-frames relative to the other in a horizontal plane.

On the front end 2 is mounted excavation equipment, for example, in the form of a return of the shovel,the handle 7, at the end of which is mounted a lifting body, such as the bucket 8. The rotation of the column 5 in the horizontal plane is accomplished by a hydraulic cylinder 9, the arrows 6 in a vertical plane by a hydraulic cylinder 19, the handle 7 is a hydraulic cylinder 11, the bucket 8 reverse shovel - hydraulic cylinder 12.

On the rear section 3 pivotally mounted dump body 13 shown in Fig. 1 in the transport position and at discharge. The translation of the body 13 from one position to another due to its rotation in the vertical plane is accomplished using a hydraulic cylinder 14.

Both hollow cylinders 9, 10, 11, 12, 14 reported in the neutral position with the corresponding section two-section pump 15 through the corresponding section of the distributors 16, 17 with safety valves 18, 19 that are configured on different levels of pressure, the outputs are communicated through the filter 20 to the tank 21. In hydroscheme work equipment provided by the backup line to the additional hydraulic cylinder 22.

Excavating equipment vehicle operates as follows.

For excavation or loading of bulk cargo from the embankment a vehicle is installed in a convenient to carry technologiesare equipment using hydraulic cylinders 9, 10, 11, 12 allows goods to be moved from the work area fill bucket 8 reverse shovels in the space above the dump body 13 is unloaded. After filling the dump body 13 of the bucket 8 reverse spade fit into the body 13. After performing the above operations, the vehicle is ready for transportation.

Unloading of bulk cargoes is carried out by tilting the body 13 by a hydraulic cylinder 14. In the case of freezing of cargo can when unloading to use excavation equipment. The combining operations in a loop by using the simultaneous response of one of the cylinders 10, 11, 12 with the hydraulic cylinder 9 or 14 two independent hydraulic circuits hydraulic control.

The economic effect is achieved by improving the operational capabilities of the vehicle.
