The lower tail gate arrangement has a second pivot axis located at an approximate center of the bale chamber when viewed in cross section.
Claims15
An agricultural round baler, comprising:
- a frame;
- and
- a tail gate arrangement carried by the frame and arranged in an arcuate arrangement around a bale chamber,
- wherein the tail gate arrangement includes an upper tail gate arrangement and a lower tail gate arrangement positioned below the upper tail gate arrangement, each of the upper and lower tail gate arrangements having a plurality of carrier elements arranged in an arcuate arrangement around at least a portion of a periphery of the bale chamber for rolling an expanding bale, the upper tail gate arrangement having a first pivot axis located at an upper, forward portion thereof, the first pivot axis located above the bale chamber, the lower tail gate arrangement having a second pivot axis located at an approximate center of the bale chamber when viewed in cross section of the baler, the upper tail gate arrangement having an open position achieved by pivoting the upper tail gate arrangement in an upward direction about the first pivot axis to the open position, the lower tail gate arrangement having an eject position achieved by pivoting the lower tail gate arrangement in an upward direction about the second pivot axis to the eject position to eject a completed bale from the baling chamber, and wherein when the lower and upper tail gate arrangements are in an upper position, the arcuate arrangement of the carrier elements of the lower tailgate arrangement is positioned at least partially under the arcuate arrangement of the carrier elements of the upper tailgate arrangement when viewed in cross section of the baler.
A method for operating a discharge sequence for an agricultural round baler comprising a frame and a tail gate arrangement carried by the frame and arranged in an arcuate arrangement around a bale chamber, the tail gate arrangement include an upper tail gate arrangement and a lower tail gate arrangement positioned below the upper tail gate arrangement, each of the upper and lower tail gate arrangements having a plurality of carrier elements arranged in an arcuate arrangement around at least a portion of a periphery of the bale chamber for rolling an expanding bale, the upper tail gate arrangement having a first pivot axis located at an upper, forward portion thereof, the first pivot axis located above the bale chamber, the lower tail gate arrangement having a second pivot axis located at an approximate center of the bale chamber when viewed in cross section of the baler, the method comprising the sequential steps of:
- sensing a full bale condition within the bale chamber, corresponding to a predetermined size of the bale;
- opening the upper tail gate arrangement by pivoting the upper tail gate arrangement in an upward direction about the first pivot axis to an open position;
- and
- ejecting the bale by pivoting the lower tail gate arrangement in an upward direction about the second pivot axis to an eject position to eject a completed bale from the baling chamber, wherein when the lower and upper tail gate arrangements are in an upper position, the arcuate arrangement of the carrier elements of the lower tailgate arrangement is positioned at least partially under the arcuate arrangement of the carrier elements of the upper tailgate arrangement when viewed in cross section of the baler.
