    The scooper-excavator is self-propelling and comprises a chassis having a roughly U-shape in its horizontal plane. A bucket-wheel is mounted to be rotatable about a horizontal axis which is fixed relative to the chassis and is engaged at least partly between the branches of the chassis. Discharge means are mounted on the chassis to discharge the product scooped by the bucket-wheel. The scooper-excavator is supported on the ground by three support means which define in the aforementioned horizontal plane three bearing points located at the corners of an isosceles triangle. Those of the support means corresponding to the corners at the base of the isosceles triangle are, in the course of the work of the scooper-excavator, permanently driving means and orientable about respective vertical axes. These driving and orientable means are located on each side of the chassis and respectively associated with the branches of the chassis. Means are provided for orienting the respective driving support means and comprise, on one hand, an actuating device connected to the driving support means by mechanical connections, and, on the other hand, a control device which is accessible to the operator and connected to the actuating device for achieving a permanent regulation of the orientation of the driving support means. The angle of orientation of one of the driving means is always equal to and of opposite direction to the angle of orientation of the other driving means.

    The invention relates to excavation means, in particular to multi-bucket rotary excavators. A multi-bucket excavator containing a rotary working body mounted on a self-propelled chassis and a conveyor for transporting the group to the dump dump is known. The closest technical solution to the invention is a self-propelled multi-bucket excavator containing a chassis with engines mounted on an axle rotor mounted on a frame buckets and a conveyor adjacent to the rotor. The chassis frame has an arrow hinged to it, on the end of which is mounted a rotor. The rotor bucket forces are transmitted through the frame to the landing gear 2}. Taking into account the length of the boom, the rotor boosters, which are increased by the boom reach, strongly load the base of the hyiaxia, which leads to an increase in its mass, a decrease in passability and a decrease in the diameter of the rotor. This adversely affects the performance of the machine. The small rosette dialtool causes the wheel to be used. The slope for the soil is low inclined. This leads to the impossibility of effectively using this excavator in the development of sticky soils. The purpose of the invention is to improve the stability of the excavator. The goal is achieved by the fact that in a self-propelled multi-bucket excavator with a supporting frame with movers, an axis fixed on the frame, a rotor with buckets mounted on the axis of the rotor and a conveyor belt attached to the rotor, the frame is arranged in a horizontal L-shaped plane, and the rotor is located between the frame in its opening, the frame ends having pivotally connected pivot brackets, the rotor is installed with the ability to interact with the mattes, and the propellers are attached to the frame ends with the possibility of turning in the horizontal plane a line between points of attachment motion teley 6brazuyut isosceles triangle can. The frame is equipped with vertical struts with beams, to which are swivel brackets fixed in pairs on racks and brackets on rollers and wedges with a drive for their movement, located between baps and brackets. Such an implementation of the excavator allowed to increase its maneuverability, in the best way, to determine the load on the propellers, and also, when comparing the small weight of the excavator, use a rotor of a larger diameter. Figure 1 shows a self-propelled multi-bucket excavator; in Figure 2, the same, front view in Fig. 3 - the same, top view; Figures 4-6 are a schematic representation of a multi-bucket excavator in possible movement options; 7 and 8 - multi-bucket excavator on the construction, perspective view. The self-propelled multi-bucket excavator contains chassis 1 with engines 2 and conveyor 4 installed on its frame 3 and rotor 5 having buckets 6. The chassis frame 3 has a U-shaped horizontal plane and its ends 7 and 8 are perpendicular to the rotor axis 9 5, which is located between the ends of the frame. The frame is installed with the possibility of rotation around the vertical axis. The chassis thrusters are attached to the ends 7 and 8 of the frame 3 and to the connecting part of the ends of its middle part 10 with the possibility of rotation around the vertical axes 11, 12 and 13 located at the points 14 15 and 16 of an isosceles triangle (FIG. 3). The frame is equipped with zn w with her hinges 17, swivel brackets 18, interacting with the rotor. The frame ends have vertical pillars 19 having horizontal beams 20. Rotor 5 is mounted on racks by means of two pairs of carrier rollers 21 and 22, with one pair of rollers 21 on top beams of 20 racks, and the other pair of rollers 22 on vertical racks 19. One a pair of carrier rollers 21 are mounted on pivoting brackets 18 supported on horizontal beams 20, which are provided with wedges 23 arranged between them and pivoting brackets, having a drive 24 of their movements. The rotor is coupled to a rotational drive 25 rotor. Between the pillars of the frame 3 there is a loading funnel located above the conveyor 4. The rotor 5 has guides in the form of rings 26. The excavator works as follows. When the rotor 5 rotates from the drive 25, the buckets 6 provide for cutting the soil and filling it with soil. Above the conveyor, 4 bucket soil is unloaded and transported to the loading zone thereof; When the rotor rotates, the propellers 2 ensure its movement in the given directions. For this, the propellers 2 fixed at the ends of the frame are turned in predetermined directions and at the same time they are rolled around the centers of rotation. In the vertical plane, the rotor is moved
    using wedges 23 as they move away from actuator 24.
    Thus, the present invention, mainly related to the layout of excavator assemblies, makes it possible to increase
    its performance by improving the distribution of loads on the chassis, increasing maneuverability and using a rotor of relatively large diameter in relation to the mass of the machine.
