SU70025A1 - Fitting to a multi-bucket excavator for closing buckets at the initial moment of their lifting - Google Patents

Description

When dredging a lot of excavators with excavators, their full power is not used because of structural defects. In particular, a major disadvantage of the known excavators is the dumping of soil from the bucket at the lower drum, which lowers the performance of the excavator and often causes debris.

The proposed device, which serves to close the KOBuieii at the initial moment of their ascent, is intended to eliminate the noted 1x deficiencies of the excavators.

A distinctive feature of the adaptation is the use of a blade, which is hinged at the lower end of the bucket frame when the two rods are flattened so that the buckets can pass between these rods and the hook when they leave the linear frame.

FIG. I shows the position of the bucket on the lower end of the KOBiHeBoii frame with the railing of the frame in the excavator and the driver next to it (dotted line); FIG. 2 — plast in FIG. one.
