The invention relates to earth moving machinery, namely, to bucket mnogovyshovyh sewer cleaners.

The purpose of the invention is to reduce the energy intensity of the cutting process and to improve the quality of cleaning the grooves.

FIG. 1 shows a ladle, total d, FIG. 2 shows section A-A in FIG. one; in fig. 3 - bb incision on i. ,

The excavator bucket includes a bottom 1, side walls 2 connected to it with rezhus 1 edges 3, made NIN convex in the direction of the cut-f5, the back wall 4 and the front cutting edge 5. The convex surface of the cutting edge of each side wall has the form, circumscribed by a logarithmic spiral. The sharpness angle of the cutting edges of the side walls decreases in the direction from the leading cutting edge.

The bucket's job is to look for.

When cleaning the ameliorative odno-i-pa channels, the bucket of the design allows jiHer to ensure the reversible operation of the multi-bucket channel cleaner. When the bucket is moving, cut off # 1Y sod 30–30 grooves of the channel slopes is separated from the array by the lower front cutting edge 5 and one of the lateral cutting edges 3, moving along bottom 1 and side walls 2, filled with

this bucket The cleaning is carried out by turning the rear wall 4. Changing the angle of the point along the perimeter of the side cutting edges 3 and giving them a convexity in the direction of cutting in the form of a logarithmic spiral, allows, as the bucket moves in the sodled soil, to alternate cutting of the roots and stems of the plants due to sliding cutting , with minimal energy consumption, improve the cutting of the turf cover and reduce its stripping from the slopes of the canals.
