For this, the arm (P) is made of two parts connected by the hinge 5 with the vertical axis 6, 7. The non-rotary part 7 P connected to the boom 3 is made with the supporting sector and has a two-arm lever 9. One arm of the two-arm lever is connected to the hydraulic cylinder (HZ) 8 controls the mechanism of rotation of the working equipment in the horizontal plane. The rotary part 6 P has a longitudinal groove in which the end of the second shoulder is placed. two shoulders lever 9. If it is necessary to develop a trench wider than the width of the bucket 15, the HZ 8 rod will be retracted. In this case, the lever 9 rotates around the hinge 10 relative to the non-rotatable part 7 P and with a finger 11 causes the rotary part P to rotate around the hinge 5 relative to the non-rotary part 7 P. 7 Il.

The invention relates to building machines and is intended for excavation.

The aim of the invention is to increase reliability while expanding the technological capabilities of the working equipment.

cylinders 14. If, for example, according to the technological conditions, it is required to develop a trench wider than the width of the bucket 15, for example, to the left of the longitudinal axis of the base machine, keeping the vertical trench walls even, then the hydraulic cylinder rod 8 is retracted. In this case, the lever 9 rotates around the hinge 10 relative to the non-rotatable part of the arm 7 with its second shoulder turns to the same angle and with the finger 11 causes the rotatable part of the arm 6 to rotate around

the same, top view; in fig. 7 is a bottom configuration.

The excavator consists of a base tractor 1 on which equipment is mounted, consisting of a rotary column 2, to which is attached an arrow 3. To an arrow 3 is attached by means of a support sector 4 a handle that can be rotated relative to a hinge 5 with a vertical axis connecting the pivot part 6 of the arm and the rotatable part 7 of the arm pivotally connected to the boom. A hydraulic cylinder 8 of control 8 is attached to part 7 of the arm, which is connected to the double-arm lever 9 by its stem, the latter being simultaneously fixed on the non-rotary part 7 of the arm and on the part 6 of the arm, respectively, with fingers 10 and 11. Bottom of longitudinal the arm has a longitudinal I groove 12. The arm part 7 is connected to the boom 3 by the hinge 13 and through the supporting sector 4 by the hydraulic cylinders 14; 9 ow The mechanism of rotation of the working equipment in the horizontal plane.

The excavator works as follows.

When developing trenches, for example, the width equal to the width of the bucket 15, the movable part of the arm and the stationary 7 are installed coaxially in the plan. The rod of the hydraulic cylinder 8 is in some middle position. The digging is driven by turning the bucket 15c by means of the hydraulic cylinder 16 or by turning the bucket 15 and the fixed part of the handle 6 relative to the hinge 13 hydro20

parts of the arm 7. For parallelism of the longitudinal axis of the rotary part of the arm 6 with the longitudinal axis of the base car 1, the boom 3 is rotated relative to the rotary column 2. The digging is also performed by turning the bucket 15 by hydraulic cylinders 16 or by rotating the bucket 15 and the fixed part 7 With respect to the hinge 13. On the non-rotatable part of the arm Ti 7 there is a supporting sector 4, which perceives arising twisting stresses in the rotatable part of the arm 6, for the same hydraulic cylinders 14 with their rods are fixed at the extreme points of the reference projector of 4.

To develop a trench, for example, to the right of the longitudinal axis of the base machine, 1, the rod of the hydraulic cylinder 8 is swiveled by the required amount and the operation is similar.

Invention Formula

The working equipment of a single-bucket excavator, which includes articulated boom, arm and bucket, hydraulic cylinders for controlling them and the mechanism for rotating the working equipment in the horizontal plane with a hinge with a vertical axis and a control hydrocyle, which differs in order to increase reliability. expansion of the technological capabilities of the working equipment, the handle is made of two parts connected by a hinge with the vertical axis, while the part of the handle connected to the boom is made with the supporting sector and a double arm is loaded with a lever, one shoulder of which is connected to the hydraulic cylinder controlling the mechanism for turning the working equipment in the horizontal plane, and

parts of the arm 7. For parallelism of the longitudinal axis of the rotary part of the arm 6 with the longitudinal axis of the base machine 1, the boom 3 is rotated relative to the rotary column 2. Digging is also carried out by turning the bucket 15 by hydraulic cylinders 16 or by overlapping the rotation of the bucket 15 and the fixed part 7 of the arm relative to the hinge 13. On the non-rotatable part of the handle Ti 7, a supporting sector 4 is installed, which perceives arising torsional tensions in the turning part of the handle 6, for the same hydraulic cylinders 14 with their rods are fixed at the extreme points of the supports the real sector 4.

In order to develop a trench, for example, to the right of the longitudinal axis of the base machine 1, the rod of the hydraulic cylinder 8 is pushed to the required amount and the operation is similar.
