RISE AND FALLING AUTOMATIC CONTROL APPARATUS FOR PICKUP PART OF BALER

摘要

The present invention relates to a device for automatically controlling ascending and descending of a pickup unit, wherein the pickup unit dispose din a baler does not colloid with a protruding natural feature. When an agricultural vehicle (for example, a tractor) connected with a baler passes through an uneven protruding natural feature, the agricultural vehicle senses the protruding natural feature and makes a pickup unit of the baler suitably ascend or descend, so the pickup unit is prevented from colliding with the pickup unit and the pickup unit can be prevented from being damaged. The device according to the present invention comprises: a first sensing unit installed in an agricultural vehicle to sense a protruding feature; a second sensing unit installed in a baler to sense that the protruding natural feature sensed by the first sensing unit passes through a pickup unit; a pickup unit connected with the baler in a hinge structure to be lifted to the ground or to go down to the ground according to upward or downward rotation thereof; a driving means connected between the baler and the pickup unit to provide a driving force for rotating the pickup unit; and a pickup unit ascending and descending control unit for controlling the driving of the driving means according to a result value obtained by comparing and determining sensing values inputted from the first and second sensing units.
