Description

The working attachment of the EO-4121 single-bucket hydraulic excavator is a bucket configured as a "backhoe." This type of attachment is designed for excavating soil below the level upon which the machine is positioned and is widely used for digging foundation pits, trenches, and other excavations. The bucket is a welded, box-type metal structure fabricated from high-strength, wear-resistant steel. Its primary components include the bottom, side walls, rear wall, and a cutting edge. Replaceable teeth are mounted on the front of the bucket to facilitate effective penetration into the ground and the breaking up of dense or frozen soil layers. The cutting edge, which bears the primary loads during excavation, is reinforced with replaceable wear plates. The side walls prevent soil from spilling, while the bottom defines the bucket's capacity and assists in transporting the material. The bucket is connected to the dipper arm via a hinge and is actuated by a hydraulic cylinder through a linkage mechanism. This configuration allows the bucket to pivot relative to the dipper arm, which is essential for cutting, scooping, and subsequently discharging the soil. A key characteristic of the backhoe configuration is that the digging process occurs by pulling the bucket toward the excavator. The cutting force is generated through the combined action of the dipper arm and bucket hydraulic cylinders, ensuring highly efficient soil excavation. The bucket’s design allows for the rapid replacement of wear-prone components—such as the teeth and cutting edge—thereby enhancing operational reliability, minimizing downtime, and reducing maintenance costs. The working implement functions as part of the working equipment (boom, stick, and bucket), providing the required motion trajectory, digging depth, and cutting force necessary for carrying out earthworks.
