Agricultural field preparation device
View Patent ↗An agricultural device associated with reduced tillage techniques in a field includes a frame and a separator supported by the frame. The separator is configured to form a strip of exposed soil in residual plant matter in the field. A crimping device associated with the separator is configured to at least partially crush stems of residual plant matter while maintaining the strip.
1. An agricultural system associated with reduced tillage techniques in a field, the agricultural system comprising:
a frame configured for attachment to a towing vehicle movable in a travel direction in a field;
one or more planter implements attached to the frame;
a plurality of crimping devices flexibly attached to the frame and extending perpendicular to the travel direction in a side-by-side configuration across a plurality of adjacent rows in the field, each crimping device of the plurality of crimping device being cylindrically-shaped and having a peripheral surface from which a plurality of helically-formed protrusions extend outwardly, each crimping device of the plurality of crimping devices further having a length that extends across at least two adjacent rows of the plurality of adjacent rows and being configured to independently roll over and at least partially crush stems of residual plant matter with adjustable down pressure; and
a separator supported by the frame in an overlapping position with at least one crimping device of the plurality of crimping devices, the separator being configured to form and maintain a strip of exposed soil in a row of the plurality of adjacent rows, the separator being positioned in a center area of the row and perpendicularly to the travel direction.
2. The agricultural system of claim 1 , wherein the plurality of helically-formed protrusions are welded to the peripheral surface.
3. The agricultural system of claim 1 , wherein each crimping device has one end that, in response to receiving an increase in terrain resistance, raises with respect to another end for maintaining a constant force applied to crush the stems of the residual plant matter.
4. The agricultural system of claim 1 , wherein each crimping device is spring-loaded with at least one compression spring.
5. The agricultural system of claim 1 , wherein the at least one crimping device is located in a leading position relative to the separator such that the at least one crimping device encounters the stems of the residual plant matter prior to the separator encountering the stems of the residual plant matter.
