SUBSTANCE: reversible drum picker bucket has symmetrically arranged cross walls with hinge-suspended cross beam with cutting edges, throw-over valve installed for overlapping charging port and hinge-connected with cross beam and cross beam and throw-over valve braking devices. Each braking device is made in form of hollow tight housing rigidly secured on cross beam and accommodating solid of revolution and stop with support side faces. Stop is installed on hinge axle for turning at reversing of picker and clamping the solid of revolution between corresponding support faces and housing. EFFECT: enhanced reliability of operation, increased service life. |
