FIELD: agriculture. ^ SUBSTANCE: felling-bunching machine (FBM) includes self-propelled chassis on which the bottom motionless part of rotary roller support is rigidly fixed. The bottom motionless part of the support is supplied by a gear wreath on an internal circle. On the top mobile part of the rotary roller support the rotary platform with the manipulator and the mechanism of turn of the platform in a horizontal plane against the frame of the self-propelled chassis is rigidly established. The mechanism of turn of the platform includes an engine and a reducer; the drive gear is in gearing with the gear wreath of motionless part of the support and is rigidly fixed on the output shaft. The manipulator is supplied on its free end by the claw-like felling unit. The device for formation of a pack of trees is executed in the form of the drum established vertically between a rotary platform and the top mobile part of a rotary roller support and with possibility of winding on the drum carrying cable. The free end of the cargo rope is supplied with a hook. The FBM has simple design, allows generating pack for logging of any volume, thus the FBM it is not made heavier by the pack. ^ EFFECT: increase of efficiency of use of machine and logging tractor; ecology improvement. ^ 4 cl, 3 dwg |
