A working equipment of a rotary excavator is known, including a rotary wheel with forging (s, mounted on the boom, a drum feeder placed in the bottom of the rotor, and t) an orthopedic 1.

The disadvantage of this working equipment lies in the significant dimensions of the feeder, and therefore of the boom.

The closest technical solution to the invention is the working equipment of a rotary excavator, including a rotary wheel with buckets mounted on the boom, a drum holder with shaft, mounted on the boom, located in the bottom of the rotor, shaft bearings, one of which is located in the drive gear of the feeder, and conveyor 2.

A disadvantage of the known device is the considerable size of the equipment and the complexity of installation.

The aim of the invention is to increase the reliability of the equipment and reduce the complexity of its installation.

The goal is achieved by the fact that the working equipment of a rotor excavator, including a rotor wheel with buckets, mounted on a boom, a drum feeder with a shaft placed in the rotor cavity, a shaft support, one of which is located in the drive drive reducer, and a conveyor belt are equipped with a support, on which the drive of the feeder is placed, with one of the supports made in the form of a stand with spherical elements at the ends, and the other support is made of a spherical element with an axis located in the same plane with the drum shaft p itatel, and installed with the possibility of longitudinal movement along the o.xi.

FIG. 1 shows the working equipment, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. I; in fig. 4 shows a section B-B in FIG. 3; in fig. 5 is a section of YYD in FIG. 3

The working equipment of the excavator includes a rotor wheel 1 with buckets 2 mounted on the free end of the boom 3 rotatably on the shaft 4. Inside the rotor wheel 1 there is a drum feeder mounted on the base 5 mounted on the boom 3.

The drum feeder consists of a drum 6 and a drive 7. The drum 6 is rigidly fixed on the shaft 8, which at one end rests on the base 5 through its own bearing support 9, and the second part enters

the gearbox 10 of the drive 7. Drive 7 except the gearbox 10 includes the engine 11, mounted with the gearbox on a common frame 12 with supports. A gear wheel 13 is seated at the end of the shaft 8, entering the gearbox 10.

The shaft 8 on the gearbox housing 10 is supported through bearings 14, the frame 12 of the actuator 7 is supported on the base 5 through the supports 15 and 16. The support 15 of the frame consists of a spherical element 17 placed on the axis 18 with the possibility of longitudinal movement on

her. A frame 19 is made on frame 12, and the enveloping spherical element 17 is enveloped.

The center of the spherical element 17 is located in a plane, running through the axis of the shaft 8. The bearing of the frame 16 is displaced relative to the support 15 by the high speed stage of the gearbox 10. It is a rack 20 with spherical elements 21 at the ends that enter spherical sockets 22 of the frame 12 and the base 5. Inside the wheel 1 are installed trays 23, limiting the discharge zone, which take the material for its further transfer to the drum 6 and the boom conveyor 24.

The equipment is operated as follows.

When the rotor wheel 1 rotates, the buckets 2 are filled with the material being developed, lift it to the top of the wheel, and in this zone they are unloaded in the range defined by the trays 23. The material falls on the drum 6, which is rotated by the drive 7 and loads the material onto the conveyor 24. If any inaccuracies were made during the manufacture or installation, then, thanks to the supports 15 and 16 of the frame 12, the actuator 7 takes a position determined by the shaft. If the axis of the shaft 8 is curved, the gearbox 10 swings around the centers of the spherical elements 17 and 21.

The presence of supports with spherical elements allows to simplify the actuator roll-up, since its exact installation is not required.

and the alignment of the axes of the gearbox and shaft, at the same time, supports with spherical elements require much space for placement, which reduces the size of the base and the working body as a whole.
