Flexible wing sections for a field cultivator
An agricultural tillage implement for use in a field. The agricultural tillage implement including a frame section and a plurality of wing sections. The frame section has a pull hitch extending in a travel direction. Each of the plurality of wing sections are coupled to the frame section and/or a wing section. The wing sections each have an articulated portion pivotal about an axis substantially perpendicular to the travel direction.
1. A plurality of wing sections coupled to an agricultural tillage implement having a frame section including a pull hitch extending in a travel direction, each wing section of the plurality of wing sections comprising:
an aft portion extending behind and connected to a transverse frame of the frame section, the transverse frame oriented transversely relative to the travel direction, the transverse frame also connected to each of the plurality of wing sections; and
an articulated portion positioned in front of the transverse frame, the articulated portion extending between and operatively connected to the transverse frame at one end and operatively connected to at least one gauge wheel at an opposite end, the articulated portion including
a plurality of shank frames position horizontally relative to each other and transversely relative to the travel direction:
a pair of longitudinal shank frame members oriented in the travel direction, one of each of the pair of longitudinal frame members positioned to carry each lateral end of each of the plurality of shank frames;
a bracket operatively connected to a portion of the transverse frame, the bracket extending downward, and including a pivot axis positioned below the transverse frame, the pivot axis positioned transversely relative to the travel direction;
wherein one end of each longitudinal shank frame member is pivotally connected at the one end to the bracket via the pivot axis, and at an opposite end each longitudinal shank frame is operatively connected to at least one gauge wheel, and
wherein pivotal movement of each of the pair of longitudinal shank frame members permits the plurality of shank frames to move below the level of the transverse frame, the plurality of shank frames and the pair of longitudinal shank frame members moving upward and downward relative to the ground below the transverse frame while traveling in the travel direction;
wherein each of the plurality of wing sections is pivotally coupled to at least a portion of the frame section and one of the plurality of wing sections,
wherein each of the plurality of wings sections is pivotally connected to at least one other of the plurality of wing sections to allow for a side-to-side flexure of the plurality of wing sections, and
wherein each articulated portion of each of the plurality of wing sections permits longitudinal flexure of each of the plurality of wing sections.
2. The plurality of wing sections of claim 1 , wherein each axis of each bracket is generally parallel with a ground surface beneath each articulated portion.
3. The plurality of wing sections of claim 1 , wherein each wing section further comprises:
a lift wheel coupled to the wing section.
4. The plurality of wing sections of claim 1 , wherein the aft section further comprises a rear auxiliary implement.
5. A plurality of wing sections coupled to an agricultural tillage implement having a frame section including a pull hitch extending in a travel direction, each wing section of the plurality of wing sections comprising:
an articulated portion positioned in front of a transverse frame of the frame section, the transverse frame oriented transversely relative to the travel direction, the articulated portion extending between and operatively connected to the transverse frame at one end and operatively connected to at least one gauge wheel at an opposite end, the articulated portion including
a plurality of shank frames positioned horizontally relative to each other and transversely relative to the travel direction;
a pair of longitudinal shank frame members oriented in the travel direction, one of each of the pair of longitudinal frame members positioned to carry each lateral end of each of the plurality of shank frames;
a bracket operatively connected to a portion of the transverse frame, the bracket extending downward, and including a pivot axis positioned below the transverse frame, the pivot axis positioned transversely relative to the travel direction;
wherein one end of each longitudinal shank frame member is pivotally connected at the one end to the bracket via the pivot axis, and at an opposite end each longitudinal shank frame is operatively connected to at least one gauge wheel, and
wherein pivotal movement of each of the pair of longitudinal shank frame members permits the plurality of shank frames to move below the level of the transverse frame, the plurality of shank frames and the pair of longitudinal shank frame members moving upward and downward relative to the ground below the transverse frame while traveling in the travel direction;
wherein each of the plurality of wing sections is pivotally coupled to at least a portion of the frame section and one of the plurality of wing sections,
wherein each of the plurality of wings sections is pivotally connected to at least one other of the plurality of wing sections to allow for a side-to-side flexure of the plurality of wing sections, and
wherein each articulated portion of each of the plurality of wing sections permits longitudinal flexure of each of the plurality of wing sections.
