Abstract

Claims (19)

1 . A seeding assembly for direct seeding comprising:

a support attached to a chassis of a seeding machine;

a hydraulic cylinder comprising an upper part and a rod; and

a seeding frame supporting a coulter blade and a double disc assembly comprising two furrow opening discs, the coulter blade and the double disc assembly being in a tandem arrangement, with minimum distance or spacing therebetween, and the coulter blade being partially located within the seeding frame,

wherein the seeding frame is attached to the support through a parallelogram system, said parallelogram system comprising a first pivot arm and a second pivot arm, and said first pivot arm being located below the second pivot arm,

wherein the hydraulic cylinder is located on a lateral side of the parallelogram system, the upper part of the hydraulic cylinder being linked to the support and the rod of the hydraulic cylinder being linked to the first pivot arm, allowing the hydraulic cylinder to transmit load to the seeding frame through said first pivot arm of the parallelogram system, and

wherein the coulter blade is partially located between the first pivot arm and the second pivot arm of the parallelogram system allowing the load applied to the seeding frame to concentrate more on the coulter blade so that said coulter blade penetrates the soil.

2 . The seeding assembly according to claim 1 , wherein the seeding frame comprises at least one coupling means allowing to couple additional seeding accessories.

3 . The seeding assembly according to claim 2 , wherein the coupling means allow coupling accessories selected from the group consisting of seed metering means, seed securing means, furrow closing and ridge forming means, and soil compacting and flattening means.

4 . The seeding assembly according to claim 1 , wherein the seeding frame comprises depth regulating means comprising gauge wheels, a rocker arm support and regulation mechanism, and a rocker arm.

5 . The seeding assembly according to claim 4 , wherein the depth regulating means further comprise a load sensor located in the rocker arm support and regulation mechanism that controls and regulates the load exerted by the load generating means.

6 . The seeding assembly according to claim 1 , wherein the coulter blade has a diameter between 16″ and 20″.

7 . The seeding assembly according to claim 6 , wherein the coulter blade has a diameter of 20″.

8 . The seeding assembly according to claim 1 , wherein the coulter blade is attached to the seeding frame through tapered roller bearings.

9 . The seeding assembly according to claim 1 , wherein the seeding frame comprises position regulating means for the coulter blade, said position regulating means comprising a plurality of vertically spaced holes.

10 . The seeding assembly according to claim 9 , wherein the position regulating means allow a height difference in contact with the soil surface between the coulter blade and the furrow opening discs, said height difference being between −10 mm and 76 mm.

11 . The seeding assembly according to claim 10 , wherein the height difference is 0 mm.

12 . The seeding assembly according to claim 1 , wherein the minimum distance or spacing between the coulter blade and the double disc assembly is between 10 mm and 62 mm.

13 . The seeding assembly according to claim 12 , wherein the distance between the coulter blade and the double disc assembly is 11 mm.
