The invention relates to earthmoving machines and is intended to improve the working equipment of excavators.

The purpose of the invention is to expand the technological capabilities of the working equipment.

Figure 1 shows the working equipment of the cleaning machine, general view; figure 2 - the same, in the form of a grab; FIG. 3 shows the process of scooping bulk material; figure 4. - the process of unloading bulk material; Fig. 5 illustrates the process of capturing and transporting piece goods.

The working equipment of the digging machine contains a bulldozer blade rotated by means of hydraulic cylinders 2 and extended by means of hydraulic cylinders placed in telescopic supports 3, boom 4, hydraulic cylinders 5 for boom control 4, handle 6, hydraulic cylinder 7 for handle 6, the working body, made in as a fork grab 8 and one of the interchangeable elements, t gu 9, double-arm lever 10, hydraulic cylinder 11

turning the fork for the grip 6 and hydraulic cylinders 12

forklift control 8.

The dozer blade 1 is equipped with a stop 13 at the rear, and a finger 14 at the top to interact with the two-arm lever notch 15 10. The forks 8 can hold various interchangeable elements: a bucket 16, a blade, a hook clip, a roller compacting the slab and others, along with the working body of the earthmoving machine.

T ha 9, a double-arm lever 10, at one end connected to the hydraulic cylinder 11, form the mechanism for turning the operating element. The telescopic supports 3 are connected to the base machine 17. The groove 15 is made in the second shoulder of the two shoulders lever 10.

Working equipment of the earthmoving machine works as follows.

Bulldozer blade 1 is extended, rotated relative to the hinge of the mount with the help of hydraulic cylinders 2. Forks 8, controlled by the hydraulic spindle 11, can be rotated in the plane of symmetry of the equipment relative to the hinge of the arm 6 and Managed with hydraulic boom 5 and 7 and boom 4 and maneuver hand 6,

it is possible to achieve an increase in the range of the working equipment. By means of hydraulic cylinders 12, the interchangeable elements of the working member, for example, the bucket 16, as well as other quick-release organs, are gripped, depending on the type of work performed. When performing loading and unloading operations related to loose, small-gritty materials, when the need arises to equip the earthmoving machinery with grab equipment, dozer blade 1 and forks 8 with a wide

In this case, the width of the blade, the bucket 16 is displaced towards each other, and then the finger 14 is inserted into the groove 15 of the two shoulders lever 10 and the working equipment is transformed into a clamshell (Fig. 2).

The hydraulic cylinder II ensures synchronous rotation of the dozer blade 1 and the forks 8 with the bucket 16.

When the hydraulic cylinder rod 11 is pulled in, the double-arm lever 10 pulls the forks 8 behind t gu 9, turning it counterclockwise. At the same time, the two shoulders lever 10, interacting with the finger 14, placed in the longitudinal groove I5, exerts pressure on the dozer blade 1, rotating it clockwise. Then, control the boom 4 and

With the help of hand 6, the purposeful movement of the working equipment and the introduction of working bodies into the material being developed is achieved. At the time of pushing the rod of the hydraulic cylinder 1J, the cutting edges of the dozer blade 1 and the bucket 16 approach each other, scooping up the material (Fig. 3). The work equipment is then moved to the place of discharge. In that

In the case of a dozer blade 1, it is moved in the desired direction with the help of an arrow 4 and a handle 6 due to the presence of a hinge connection in the form of a feather 14 placed in the groove 15, the hydraulic cylinders

2 and 3 are thus set to the floating position.

The subsequent duty cycle is similar. Such working equipment can also carry out the capture of various piece goods and objects and their transportation (Fig. 5).
