Claims15
A seed coulter arranged to place one or more inputs in a groove behind a tine of a direct seed drill for field crops, the direct seed drill comprising one or more tines for soil tillage, and each tine comprising a front and a back, and the seed coulter comprising at least one delivery channel for carrying said input into the groove behind the tine, wherein:
- the seed coulter is arranged for displaceable connection to the tine, wherein the seed coulter is freely displaceable in the longitudinal direction of the tine between a lower position and an upper position;
- the seed coulter is arranged for connection to a depth-control device for keeping a seeding depth of the seed coulter constant when a working depth of the tine is lowered or raised during seeding;
- and
- the seed coulter comprises an attachment for connection to a rotary joint on the back of the tine, the rotary joint forming a rotary axis directed vertically or substantially coinciding with the longitudinal direction of the tine.
A seeding unit for a direct seed drill for field crops,
- wherein the seeding unit comprises a seed coulter, wherein the seed coulter is arranged to place one or more inputs in a groove behind a tine of the direct seed drill for field crops, the direct seed drill comprising one or more tines for soil tillage, and each tine comprising a front and a back, and the seed coulter comprising at least one delivery channel for carrying said input into the groove behind the tine, wherein:
- the seed coulter is arranged for displaceable connection to the tine, wherein the seed coulter is freely displaceable in the longitudinal direction of the tine between a lower position and an upper position;
- the seed coulter is arranged for connection to a depth-control device for keeping a seeding depth of the seed coulter constant when a working depth of the tine is lowered or raised during seeding, and the seed coulter is connected to the tine;
- and
- the seed coulter comprises an attachment for connection to a rotary joint on the back of the tine, the rotary joint forming a rotary axis directed vertically or substantially coinciding with the longitudinal direction of the tine.
A direct seed drill for field crops, wherein the direct seed drill comprises a plurality of seeding units, wherein the seeding units comprise a seed coulter, wherein the seed coulter is arranged to place one or more inputs in a groove behind a tine of the direct seed drill for field crops, the direct seed drill comprising one or more tines for soil tillage, and each tine comprising a front and a back, and the seed coulter comprising at least one delivery channel for carrying said input into the groove behind the tine, wherein:
- the seed coulter is arranged for displaceable connection to the tine, wherein the seed coulter is freely displaceable in the longitudinal direction of the tine between a lower position and an upper position;
- the seed coulter is arranged for connection to a depth-control device for keeping a seeding depth of the seed coulter constant when a working depth of the tine is lowered or raised during seeding, and the seed coulter is connected to the tine;
- and
- the seed coulter comprises an attachment for connection to a rotary joint on the back of the tine, the rotary joint forming a rotary axis directed vertically or substantially coinciding with the longitudinal direction of the tine.
