Description

The invention relates to the excavation and movement of soil, in particular to the working equipment of a single-bucket backhook excavator with cable management, mainly for fragments of trenches by means of a wall in the ground.

The purpose of the invention is to increase the stability of the excavator when opening a trench to an increased depth.

The drawing shows the working equipment of the single-bucket excavator shovel.

Working equipment of the single-bucket excavator 1 back shovel: includes boom 2 with block 3 and block 4, which goes around the hoisting rope 5, arm 6 pivotally connected to the boom, bucket 7 pivotally connected to the arm. On the bucket 7, a block 8 is installed, which bends around the haul rope 9 fixed in the lower part of the arm. The bucket 7 is made with emphasis. 10 to limit its rotation. Block 4 is placed in the upper part of the shooter at a distance of 0.6-0.8 of its length from the support part.

The working equipment works in an obscure manner.

iС

At the beginning of the working cycle (position A), the boom 2 is lowered and the handle 6 occupies a vertical position. At the end of the cycle, when unloading, the boom 2 lifts and the arm 6 occupies the vertical position B. The bucket 7 has a corresponding design, allowing Composer G. Novikova Editor M.

The starting load and unloading should be carried out from the vertical position of the handle.

When the rope 9 is tightened, the bucket 7 from the vertical position A rotates and occupies the optimum position for cutting the soil in the path of the arm 6 due to twofold pulling force. When the rope 9 is loosened, the bucket in position B under the action of its own weight and soil weight turns and the soil unloaded in otial. The stop 10 does not allow the bucket 7 to turn to the outside in a more vertical position when lowering it into a trench.
