Abstract

An agricultural device that can include a frame; and a plurality of roller-crimping devices supported by the frame arranged in at least one row oriented in a direction that is transverse to a direction of travel of the agricultural device. Each of the plurality of roller-crimping devices having an exterior surface configured to at least partially crush stems of residual plant matter, and being individually movably mounted to the frame such that each of the plurality of roller-crimping devices will move at least vertically with respect to the frame when subjected to a temporary increase in resistance caused by an encounter with a non-uniform region in the field.

First claim

The invention claimed is:

1. A modular rolling crimping device for crushing and terminating cover crops or plants materials comprising:
a mounting plate to affix the device to an agricultural frame,
parallel arms linkages pivotally attached to the mounting plate on a rearward side and extending away from the mounting plate having a crossbar member on a frontward side,
a tensioning mechanism attached to the parallel arm linkages at the crossbar member on the frontward side and connecting to the mounting plate on the rearward side, the tensioning mechanism connected between the crossbar member and the mounting plate such that the tensioning mechanism is about parallel relative to the ground,
a rolling-crimping cylindrical drum attached to the parallel arm linkages such that the rolling-crimping cylindrical drum can rotate and the rolling-crimping cylindrical drum comprising a plurality of outwardly projecting blades,
the parallel arm linkages comprising a telescoping parallel arm system,
the telescoping parallel arm system comprising a mounting plate with rigidly connected open channel parallel arms having internal telescoping parallel arms rigidly connected to the crossbar member,
the telescoping parallel arms sliding within the open channels to fluidly and dynamically adjust in height to tension provided by the tensioning mechanism,
the tensioning mechanism connected between the crossbar member and the mounting plate such that the tensioning mechanism is about parallel relative to the ground, a stop bolt positioned perpendicular through the open channel and the telescoping parallel arms to manipulate a minimum and maximum height adjustment ramie.

2. The modular rolling crimping device of claim 1 , each of the plurality of blades arranged evenly about the cylindrical drum.

3. The modular rolling crimping device of claim 2 , the plurality of blades arranged about the cylindrical drum in a helical pattern.

4. The modular rolling crimping device of claim 1 , further comprising a stalk guide separator.

5. The modular rolling crimping device of claim 1 , the tensioning mechanism is a pneumatic cylinder.

6. An agricultural device
comprising: a frame; and
a plurality of modular roller-crimping devices supported by the frame arranged in at least one row oriented in a direction that is transverse to a direction of travel of the agricultural device,
each of the plurality of modular roller-crimping devices having an exterior surface configured to at least partially crush stems of residual plant matter, and being individually movably mounted to the frame such that each of the plurality of roller-crimping devices will move at least vertically with respect to the frame when subjected to a temporary increase in resistance caused by an encounter with a non-uniform region in the field,
each of the plurality of modular crimping devices for crushing and terminating cover crops or plants materials comprising:
a mounting plate to affix the device to an agricultural frame,
parallel arm linkages pivotally attached to the mounting plate on a rearward side and extending away from the mounting plate having a crossbar member on a frontward side,
a tensioning mechanism attached to the parallel arm linkages at the crossbar member on the frontward side and connecting to the mounting plate on the rearward side, the tensioning mechanism being connected between the crossbar member and the mounting plate such that the tensioning device is about parallel relative to the ground,
a rolling-crimping cylindrical drum attached to parallel arm linkages such that the rolling-crimping cylindrical drum can rotate,
the parallel arm linkages comprising a telescoping parallel arm system, the telescoping parallel arm system comprising a mounting plate with rigidly connected open channel parallel arms having internal telescoping parallel arms rigidly connected to a crossbar member,
the telescoping parallel arms sliding within the open channel parallel arms to fluidly and dynamically adjust in height to tension provided by the tensioning mechanism, the tensioning mechanism connected between the crossbar member and the mounting plate such that the tensioning mechanism is about parallel relative to the ground, a stop bolt positioned perpendicular through the open channel allowing the telescoping parallel arms to manipulate a minimum and maximum height adjustment range.

7. The agricultural device of claim 6 , the plurality of roller-crimping devices comprising at least one row middle unit.

8. The agricultural device of claim 6 , the plurality of roller-crimping devices comprising at least one strip unit.

9. The agricultural device of claim 6 , the plurality of roller-crimping devices comprise at least two row middle units.

10. The agricultural device of claim 8 , wherein the at least one strip unit is flanked on opposite sides by a respective one of at least two row middle units.

11. The agricultural device of claim 8 , the at least one strip unit is positioned on the frame to operate on plant material located in a planted row area.

12. The agricultural device of claim 9 , the at least two row middle units are positioned on the frame to operate on plants located between planted rows.

13. The agricultural device of claim 10 , each of the at least one strip unit and the at least two row middle units are attached to the frame and located alternately in rows so that adjacent ones of the plurality of roller-crimping devices are located in a different row.

14. The agricultural device of claim 13 , the at least two row middle units are located in a different row than the at least one strip unit.
