The invention relates to agricultural and construction engineering, in particular to machines used in land reclamation.

The closest technical solution known is the working equipment of a hydraulic excavator, having a handle, the main working body in the form of a bucket connected in series with it by a common hinge and a narrow additional working body located behind it, control hydraulic actuator, the mechanism of which is mounted on the handle and st. It is connected with the last organ, and the fixed connection of the bucket with the hand or with an additional working body. Additional working body is made in the form of a loosening rack O 3.

A disadvantage of the known equipment is the limited technological capabilities for reclamation work, including with the passage of narrow cracks PL laying drainage pipes

The purpose of the invention is the expansion of the technological capabilities of the working equipment.

This goal is achieved by the fact that in the working equipment of a hydraulic excavator, an additional working body is made in a narrow scoop, in the bottom of which a window is made with a width equal to the width of the narrow scoop, and the main bucket is equipped with its placement in the cavity of a narrow bucket.

FIG. 1 shows the working equipment, side view; in fig. 2 is the same, the process of digging with the posterior jaw 5 in FIG. 3 - the same, the process of ejection of the soil from the cavity of the posterior jaw; in fig. 4 - Vic L in FIG. one; in fig. 5 is a view B in FIG. 1.

The working equipment of a hydraulic excavator consists of a main bucket 1, equipped with teeth 2, a bottom 3 and an unloading knife 4, which is connected with a hinge 5 to handle 6, and a narrow bucket 7 equipped with teeth 8 and through a two-lever linkage 9 coupled with hydraulic control 10 laziness.

In the lower part of the bottom 3 of the anterior jaw, longitudinal ribs 11 are installed.

the main position of the main bucket 1 and the installation of the teeth 2 and 8 at the same level, in the longitudinal ribs 11 and the side walls of the narrow bucket 7 there are holes 12 with the possibility of fixing the pin 13.

To install the main bucket 1 in the off position in the upper part of it is mounted eyelet 14,

10 cooperating with the pro-horn 15 of the arm 6. The fixation is secured by the pin 16.

Working equipment works as follows.

15 With a trench section equal to the width of the bucket, the main bucket 1 is turned on. In this case (Fig. 1), the narrow bucket 7 adjoins the bottom 3 of the main bucket 1 and is fixed by pin 13 through coaxial

holes 12 in the side walls of the narrow bucket 7 and the longitudinal ribs 11. The discharge knife 4 is located in the cavity of the narrow bucket 7, and the tooth 2

5 and 8 are set at the same level (Fig. 5).

The rotation of both buckets relative to the hinge 5 of attachment to the handle 6 is carried out by means of the hydraulic control drive 10 through the lever-pull two-link 9.

With a snatch of narrow trenches, a narrow additional bucket 7 is put into operation. Initially, using

5 of the hydraulic actuator 10, both buckets turn clockwise to the extreme position until the holes of the lugs 14 and 15 are aligned and the main bucket 1 is fixed by the pin 16 (Fig. 2).

- e After that, pin 13 is removed and the process of excavation is carried out with the formation of a narrow channel. The ground, between the side walls of the narrow bucket 7, pulled out with the unloading knife 4 as the narrow bucket 7 approached the main bucket 1 (Fig. 3). The narrow bucket 7 is also controlled by the hydraulic cylinder 10 through a two-link lever linkage 9.

The proposed design of the working equipment will significantly expand the technological capabilities of hydraulic excavators and can be used in various construction areas for land reclamation in rural areas.
