Rise and Falling Automatic Control Apparatus for Pickup Part of Baler

摘要

When the agricultural vehicle (for example a tractor) to which the baler is connected passes through an uneven protruding object, the picking up unit of the baler is appropriately raised and lowered by sensing the protruding object so that the pick-up unit does not collide with the protruding object An apparatus for automatically controlling an up and down movement of a pick-up unit so that a pick-up unit provided in a bailer does not collide with a protruding object during traveling, the apparatus comprising: 1 sensing unit; A second sensing unit installed on the bailer for sensing that the protruded object sensed from the first sensing unit passes the pickup unit; A pick-up unit connected to the baler in a hinge structure so as to be lifted or lowered to the ground according to an upward or downward rotation; A driving means connected between the baler and the pick-up unit so as to provide a driving force for rotating the pick-up unit; A pickup unit ascending / descending control unit for comparing and sensing the sensing values inputted from the first and second sensing units and providing driving control of the driving means according to the determined result values; Up / down automatic control device of a pick-up unit for a baler which is configured to include an automatic up /
