FIELD: construction. ^ SUBSTANCE: invention is related to earth-moving machines, namely to working equipment of single-bucket excavator. Working equipment of single-bucket hydraulic excavator comprises handle 1, bucket 7, fixed by means of bracket 5 on handle 1, hydraulic cylinder 9 for bucket 7 rotation in horizontal plane and hydraulic cylinder 2 for bucket 7 rotation in vertical plane. Moreover, bracket 5 is connected to bucket 7 by finger 8, and hydraulic cylinder 9 for bucket rotation in horizontal plane is connected to bracket 5 and bucket 7 with the help of spherical hinges 10. Working equipment additionally comprises traction rod 3, which is fixed in bracket 5 by means of cylindrical hinges 6 and hydraulic cylinder 2 for rotation in vertical plane, and two levers 4, which are fixed in handle 1 and traction rod 3 symmetrically to traction rod 3. Hydraulic cylinder 2 for bucket 7 rotation in vertical plane is fixed by its one end on handle 1, and by the other - in traction rod 3. Hydraulic cylinder 9 for bucket rotation in horizontal plane is fixed with one end in bucket 7, and with the other one - on bracket 5. ^ EFFECT: improved operational properties, simplified design and reduction of cost. ^ 2 cl, 3 dwg |
