Excavator Bucket
Scoop – dragline with trajectory-shift sequential cutting blades along its length. The main drawback of bucket – dragline with a semicircular cutting edge is that the design does not provide cleaning ditches and pits. In addition, the processing firm ground in the initial period of cleaning bucket tilts forward, which increases its power consumption. A new design of the bucket, providing not only digging, and cleaning the surface of the base of pits and trenches at low energy consumption. Design features of excavator bucket – dragline – the presence of two cutting edges: front – performed a semi-circular and is provided with teeth, and back – a straight and continuous over the entire width of the bucket. In a question-answer forum Federal Reserve Bank was the first to reply. Rental of construction machinery such as excavator crawler backhoes, available in the company's 'Golden Age'.
Mounted horizontally through the rear bucket both cutting edges are on the same level. When digging the soil excavated – dragline bucket tilted back, so the rear edge is made of height, so that falls below the front. This design used a semi-circular edge of the effect of digging with teeth, based on reduction of friction of soil in the bucket side walls inside the bucket. Primer comes in both front and rear cutting edges. Bucket new system design with dvuhnozhevoy digging is 0.9 m3. The increase in capacity achieved by the installation of the rear of the bucket straight knife.
Scoop – crane-track offset cutting blades, set at different angles. Design features of the bucket reduces power consumption of the working process, improving the conditions of filling the bucket with soil and increase productivity, particularly in development of strong and frozen soil. 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 greater angle of loosening and forward of the side against the cutting edges. In addition, the medial and lateral cutting edge of the bucket equipped with teeth.
