 The invention relates to multi-purpose earth-moving machines, in particular, single-bucket hydraulic excavators equipped with mechanisms for replacing the working bodies.

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

FIG. 1 shows the working equipment of a hydraulic excavator, general view; fig 2 is the same, equipped with a bucket; in fig. 3 view A in FIG. 2

The working equipment of the hydraulic excavator consists of the boom 1, the arm 2, pivotally attached to the boom and controlled by the hydraulic cylinder 3. The arm 2 is equipped with a device 4 for connecting the shafts 5 to the arm 2 о. It has a traverse pivotally mounted on the arm 2 6 with a wedge protrusion 7 and a retainer 8, an etched hydrodipindrome 9; On the bucket 5, guides 10 are fixed, forming a wedge groove with inclined surfaces for connection with the wedge-protrusion 7; A double-jaw grip of jaw 11 of which is rigidly fixed on traverse 6 to forms an L-shaped hook with it, and jaw 12 is set to rotate in a plane perpendicular to the plane of rotation of traverse 6, and is controlled by a hydraulic cylinder 13. The bottom of the bucket 5 is fitted with a covering jaw grip with a safety visor 14, the movable jaw 12 is equipped with a ca-mo ™ settable sponge 15

, about - . (Equipment operation is carried out by

with as follows

1 „Equipment according to nos. 1 and 2, that is, so that the turning jaw of the grip has a self-adjusting sponge.

In the initial stage, with the help of a grip, oversized stones and bulgashikov, logs, etc. are collected, the removal of which from the construction site is always associated with certain difficulties. The load is clamped between the fixed PI of the movable 12 jaws of the grip of the hydrocylinder 3, and the self-alignment of the sponge 15 contributes to the actual seizure of the load. Subsequently, the load is lifted by turning the yoke 6 and the handle 2 and moves to the place of unloading.,

If it is necessary to preliminarily disintegrate the soil before it is excavated, the device can work as a gripper. The loosening of the soil is performed by the unsteady jaw i 1 with hydraulic strings 9 and 3. In this case, the movable jaw 12 can be moved inside the jaw 1i.

If it is necessary to excavate the soil and load it into a vehicle, the working equipment is equipped with: a bucket 5 "For this bucket, 5 kpzs will be delivered to the ram down, the wedge 7 traverse 6 with a narrow end, as far as possible, into the guides 10 fixed on the bucket 5, and fix it with the help of the latch 8. The jaws of the grip are located behind the bottom of the bucket 5. The working equipment is ready for excavation work. The digging of the soil occurs, ts11T by extending the rod of the hydraulic cylinder 9 5 which acts on the traverse 6 s fixed on the bucket with a bucket 5. Thanks to the visor on the bucket 14, the bucket is easily inserted into the soil and protected from getting into the bucket. tsuku bucket 5

and the capture of the remains of reinforcement, wires, cables, etc. The bucket 5 is detached in reverse order.

The availability of a two-jaw grab at the working equipment allows us to quickly move from excavating to loading and unloading of individual loads.
