Abstract
The present invention provides a tillage point having a ground engaging structure configured to adjust with respect to the ground so that the tillage point can flexibly adapt to various field conditions. The ground engaging structure can comprise wings for increasing soil fracture below the ground surface and/or a cover board for moving soil along the ground surface. The ground engaging structure can variably adjust using an actuator, such as a hydraulic cylinder, connected to linkage which can move the ground engaging structure through multiple angles about a pivot point during tillage operations. In addition, a controller can adjust the actuator to maintain an angle of the ground engaging structure according to a location on a prescription map.
Claims20
A tillage tool, comprising:
- a shank mount including a shank connected at one end thereof;
- a body connected to a free end of the shank and configured to engage soil along a direction of travel;
- a nose connected to and extending from the body in the direction of travel;
- a ground engaging structure disposed above the nose, the ground engaging structure extending outwardly relative to the body in lateral directions with respect to the direction of travel;
- linkage including a plurality of links connected together, more than one link of the plurality of links positioned over a portion of a lateral surface of the shank, the linkage connected to at least one of the body and the ground engaging structure;
- and
- an actuator connected to the linkage, the actuator and the linkage being configured to actuate the ground engaging structure to move with respect to at least one pivot point positioned on at least one of the body and the ground engaging structure to adjust an orientation of the ground engaging structure with respect to the ground.
An agricultural implement, comprising:
- a tillage tool framework configured to be towed behind a vehicle in a direction of travel, including a plurality of tillage tools mounted to the tool framework, each tillage tool of the plurality of tillage tools including
- a shank mount configured at one end to mount to the tool framework and including a shank connected to an opposite end thereof;
- a body connected to a free end of the shank and configured to engage soil along the direction of travel;
- a nose connected to and extending from the body in the direction of travel;
- a ground engaging structure disposed above the nose, the ground engaging structure extending outwardly relative to the body in lateral directions with respect to the direction of travel;
- linkage including a plurality of links connected together, more than one link of the plurality of links positioned over a portion of a lateral surface of the shank, the linkage connected to at least one of the body and the ground engaging structure;
- and
- an actuator connected to the linkage, the actuator and the linkage being configured to actuate the ground engaging structure to move with respect to at least one pivot point positioned on at least one of the body and the ground engaging structure to adjust an orientation of the ground engaging structure with respect to the ground.
