Excavator Bucket

Excavator bucket – dragline with trajectory-shift sequential cutting blades along its length. The main disadvantage of excavator bucket – draglines with a semicircular cutting edge is that the design does not provide stripping trenches and pits. In addition, the processing firm ground in the initial period of stripping bucket topples forward, which increases its energy consumption. A new design of the bucket, providing not only digging, and cleaning of the ground surface pits and trenches at low energy consumption. Feature construction excavator bucket – dragline – the presence of two cutting edges: front – performed a semi-circular and is provided with both cutting edges are located on one level. While digging the soil excavated – dragline bucket tilted back, so the rear edge is made of height, so that falls below the front.

In this design used the effect of digging a semi-circular edge with teeth, based on reduction of friction of soil in the bucket sidewalls inside the bucket. Primer comes in both front and rear cutting edges. Bucket capacity of the new designs with system digging is 0,9 m3. The increase in capacity achieved by the installation of the rear of the bucket straight knife. Excavator bucket – dragline-track bias cutting knives installed at different angles. The construction features bucket reduces power consumption of the working process, improving the fill the bucket with soil and increase productivity, particularly when development of strong and frozen soils. The essential difference between this excavator bucket – dragline from known analogues is the construction of the middle part of cutting edge width of the V / 3 (B – bucket width) having a wider angle of loosening and extended forward from the side cutting edges. Furthermore, the average and the side cutting edge of the bucket fitted with teeth.
