Description

one

The invention relates to the field of construction engineering, in particular to the working equipment of a single-bucket excavator, i.e., to it means of quick-detachable attachment of the bucket to the handle.

Working equipment of the single-bucket excavator according to ed. St. No. 386076 includes a handle with an adapter, a bucket and a block hoist block. In order to provide accelerated conversion of the bucket, the adapter is made with a folding gripper installed with the possibility of fixing it relative to the bucket with your fingers and a block of polyspast bucket mounted on it. To attach the bucket to the handle, the latter, together with the adapter, is lowered onto the bucket, while the grip is in the open position. Bucket lugs are inserted into the adapter lugs and secured with your fingers, then the hinged grip is locked with your fingers.

A disadvantage of the known equipment is that the attachment of the adapter to the bucket is carried out with the help of ears and fingers, which make it difficult to guide the handle to the bucket, and the fixation of the folding grip with your fingers and ears increases the complexity of refitting the excavator.

In order to simplify the design of the working equipment, one end of the adapter is made in the form of an open gripper, and the folding gripper is provided with a drive made, for example, in the form of a hydraulic cylinder.

The drawing shows the working equipment single-bucket excavator unassembled.

The working equipment contains a handle 1 with an adapter 2, a ladle 3, a block 4 of a bucket polyspast and a pull 5.

Adapter 2 has a folding gripper 6 with a drive made in the form of a hydraulic cylinder 7. One end of the adapter is made in the form of an open gripper 8. T ha 5, a handle 1, a block 4 and a folding gripper 6 are connected to each other by means of fingers. The bucket 3 has cylindrical elements 9 and 10 for engaging with grippers 6 and 8.

Works equipment excavator as follows.

Combine the longitudinal axes of the elements 9 and 10 with the axes of the grippers 6 and 8 by lowering the handle on the bucket. Next include the cylinder 7 and turn the grip 6 in the vertical plane.

At the same time, the claws 6 and 8 fix the bucket on the handle, which facilitates the combination of the fastening elements due to their self-centering. The presence of an open grip from one end of the adapter and a folding grip drive furthermore simplifies the design and reduces the laboriousness of re-equipping the excavator by half.

Formzla invention

Working equipment of the single-bucket excavator according to ed. ev No. 386076, GTC from the fact that, in order to simplify the construction, one end of the adapter is made in the form of an open grip, and the folding grip is equipped with a drive made, for example, in the form of a hydraulic cylinder.
