The invention relates to earth-moving machines, in particular to single-bucket excavators, and to be used in cracking a frozen substance with an excavator.

The purpose of the invention is to simplify the construction of the equipment and reduce labor costs for its erection.

Fig. 1 shows the working equipment of the single-bucket excavator - a back shovel with a breaking hammer, side view; Fig. 2 is a side view of the working equipment insert with a breaking hammer; on fig.Z - the same, top view; on figure 4 - breaking hammer, rear view; on fig.5 - the same, side view; figure 6 is the same, a longitudinal section.

The working equipment of the single-bucket-iro excavator - a backspit contains a handle 1, a bucket 2 connected to the handle 1 with the possibility of hinged rotation, mounted on the handle; 1 hydraulic cylinder 3 turns of the bucket 2 and a cracking hammer 4. Last mounted on the handle 1 with the possibility of a hinge rotation around the axis 5 of the hinge of the rotation of the bucket 2 and located between the handle 1 and the bucket 2.

The breaking hammer 4 is mounted on the handle 1 by means of an intermediate insert 6, which is hinged to the handle 1 and made in the form of a bottomless box with a cover plate 7. In the latter there is an upper part of the housing 8 of the breaking hammer 4, and the insert 6 is mounted on the covering sheet plate 7 heck 9.

The hydraulic cylinder 3 of the rotation of the bucket 2 is connected to the intermediate insert 6 "The bucket 2 is fixedly fixed to the insert 6 at an angle of more than 60 between the front edges of the 10 side

 walls 11 and a breaking hammer 4. The cover plate 7 of the insert 6 is made with a through hole 12. The breaking hammer 4 has a hook 13 that is passed through the hole 12 and supported on the latch 9, by means of which the hammer 4 is suspended with equalization of approximately 15 mm of the fence 14 between its upper surface and. the inner surface 16 of the plate 7.

The length of the hammer 4 is equal to the height of the bucket 2. FIG. I the dotted line shows the extreme position in which the bucket 2 can be rotated with the breaking hammer 4 attached.

Ladle; 2 is fixedly fixed to the insert with the help of axial pins 17 and 18 and has an additional 19.

The body 8 of the hammer 4 has an upper part with vertical surfaces and is beveled downwards towards the cutting tool 20 made, for example, of wear-resistant steel.

Between the cutting tool 20 and the body 8 there is a gap of 21 "approximately 20 mm. The fastening of the cutting tool 20 is based on a groove 22, made in its connecting part 23, which is inserted into the body 8. The locking plate 24 passes into the groove 22 through the hole 25 of the body 8 and the groove 22 is already filled by an amount corresponding to the gap 21, and which is used to attach the teeth of an excavator.

Box 6 provides an additional eyelet 26.

The equipment works as follows.

The breaking hammer 4 can be inserted freely from below into the insert 6. In this case, the hook 13 of the hammer A passes through the opening 12. Then the latch 9 manually, electrically or hydraulically turns to the position shown in FIG. 3, thereby preventing the hammer from falling out 4.

The gap 14 remains between the upper surface of the body 8 of the hammer 4 and the lower surface of the plate 7 when the hammer 4 is lifted, supported by the hook 13.

When the hammer 4 hits the ground with the help of the handle control system 1 of the working equipment, the cutting tool 20 is first inserted into the ground and stops in its surface layer. This is followed by a blow caused by a considerable body weight 8. This blow causes an additional wedge-shaped introduction of the cutting tool 20 into the ground. By virtue of the gap 14 provided for the inter-engaging handle, a bale, connected to the handle with the possibility of hinge rotation, mounted on the handle

J. A hydraulic cylinder for turning the bucket and a breaking hammer, which is mounted on the arms with the possibility of a hinged rotation around the axis of the hinge of the rotation of the bucket and is located between the handle and

10 bucket distinguishing with

By the fact that, in order to simplify the equipment design and reduce the labor costs for its reassembly, the breaking hammer is mounted on the handle by means of an intermediate insert, which is pivotally connected to the handle, made in the form of a bottomless box with a cover plate, in which upper part of the hull

Claims (1)

by the inset 6 and the hammer 4, on the next 25 angle of more than 60 between the front edges of its side walls and the breaking hammer, the cover plate of the insert is filled with a through hole, and the breaking hammer has a 30 ny on its side, pierced through the cover plate and the hook supported on the latch, by means of which the hammer is suspended with the formation of a gap between its upper top stage of the system of the handle 1 and the bucket 2 shock impact on the breaking hammer 4. Thus, a three-stage impact occurs, which affects the efficiency of loosening the soil and reducing the impact loads on the working equipment and excavator as a whole.
