초록 ▼

A towable soil pulverizer having a longitudinal center section, and foldable wings mounted by hinges on opposite sides of the center section to fold upwardly or downwardly about substantially longitudinal hinge axes. The wings and center section have ground working rollers. Each hinge has a spaced ball joint and guide roller in roller slot. A wing float axis for each wing extends substantially perpendicular to the longitudinal hinge axis in a transverse direction, each wing also being pivotal about the float axis. The hinge design with the float axis prevents weight transfer between the center section and wing sections when the pulverizer operates over uneven soil, to provide uniform soil conditioning over the width of the pulverizer. The center section rollers are positioned ahead of (or behind or co-linear with) the wing rollers. Components of the ball joint and roller guide in slot are fixedly and non-rotationally attached to the center section.

1. A towable agricultural implement for working the soil, comprising in combination a longitudinally extending center section including a center section frame with leading and trailing edges and foldable wings mounted on opposite sides of the center section, each wing having a wing frame with leading and trailing edges; the foldable wings being hinged at their inner ends to opposite sides of the center section and pivotable about a longitudinal hinge axis to fold upwardly over the center section for transport or to unfold downwardly from the folded position for field operation; the center section and wings having ground-working elements; each wing being connected to the center section by a hinge having a ball joint located at said center section frame and wing frame leading edges and a guide roller located at said wing frame trailing edge and rotatable received in a vertical roller slot formed by a slotted retainer bracket extending from said center section frame or said wing frame at a respective center section or wing frame trailing edge; the ball joint having one of a ball and socket attached to the center section at a respective opposite side of the center section, and the other of the ball and socket attached to the wing at a respective wing inner end; the guide roller in roller slot having one of the guide roller and slotted retainer bracket attached to the center section, and the other of the guide roller and slotted retainer bracket attached to the wing; a wing float axis passing through the ball joint and extending perpendicular to the longitudinal hinge axis in a transverse direction, the wing being pivotal about the float axis and the extent of the pivoting being determined by the ambit of the floating motion of the roller in the roller slot; the hinge preventing substantial weight transfer between the center section and wing section when the implement operates over uneven soil and the guide roller in the roller slot is positioned between the ends of the slot; each said ball joint and said guide roller in roller slot hinge being positioned generally along a respective longitudinal hinge axis with said ball joint located in spaced relation in front of said guide roller in the roller slot; and each said guide roller in a respective roller slot restraining a respective wing against movement relative to said center section, except for limited rotation around said wing float axis. 2. The towable agricultural implement of claim 1, wherein the ball of the ball joint is mounted to and toward the front of the center section, the socket of the ball joint is mounted to the wing section, the guide roller slot is mounted to and toward the rear of the center section, and the guide roller is mounted to the wing section. 3. The agricultural implement of claim 1, wherein the wing float axis intersects the hinge axis. 4. The agricultural implement of claim 1, wherein the wing float axis is perpendicular to the hinge axis. 5. The agricultural implement of claim 1, which includes: each said ball joint being aligned with a respective longitudinal hinge axis with one of said ball and socket being located behind the other of said ball and socket.
