Abstract

In accordance with an example embodiment, a method and a machine for planting seeds or plants in a field to enable a planting of the seeds or plants in an established spacing based on two-dimensional coordinates output by a positioning system and the slope of the field in the working direction.

First claim

What is claimed is:

1. A method for planting seeds or plants in a field, comprising the following steps:
making available a machine for planting the seeds or plants, the machine movable over the field in a working direction and equipped with a positioning system that outputs two-dimensional, horizontal coordinates,
establishing a spacing measured in the working direction, the seeds or plants being planted in the field with the spacing between adjacent seeds or plants,
determining a slope of the field along the working direction of the machine,
planting the seeds or plants at the established spacing based on the two-dimensional coordinates output by the positioning system and the slope of the field in the working direction, and
activating the machine to plant a seed or plant when x=l target ·cos (α), where x is a horizontal distance traveled since the last activation according to the two-dimensional positioning system, l target is the established spacing, and α is the determined slope of the field.

2. The method of claim 1 , wherein the slope of the field is determined by means of at least one of a slope sensor, elevation information made available from the positioning system which comprises at least one antenna, and a three-dimensional map of the field.

3. The method of claim 1 , wherein the machine comprises a plurality of seeding or planting devices disposed laterally side by side transverse to the working direction, which are controlled separate from each other to maintain a two-dimensional pattern of the planted seeds or plants.

4. The method of claim 3 , wherein in addition to the spacing of adjacent seeds or plants in the working direction of the machine, at least one parameter of the pattern relates to the relative offset of seeds or plants in the working direction of the machine of two rows that are adjacent along the working direction of the machine.

5. The method of claim 4 , wherein the machine as it traverses adjacent swaths of the field is controlled corresponding to a position of the seeds or plants across the working direction in order to enable subsequent work in the field in a direction running at least one of across and diagonal to the working direction of the machine.

6. An arrangement for planting seeds or plants in a field, having a machine for planting the seeds or plants, the machine movable over the field in a working direction and coupled to a positioning system that outputs two-dimensional, horizontal coordinates, having:
means for establishing a spacing measured in the working direction at which adjacent seeds or plants are to be planted in the field,
a device for determining a slope of the field along the working direction of the machine, and
a control means, connected by signal transmission to a seeding or planting device for planting the seeds or plants, said control means being operable to control the seeding or planting device and plant the seeds or plants in the established spacing in the field, based on the two-dimensional coordinates output by the positioning system and the slope of the field in the working direction;
wherein the control means is operable to activate the seeding or planting device to plant a seed or plant when x=l target ·cos (α), where x is a horizontal distance traveled since the last activation according to the two-dimensional positioning system, l target is the established spacing, and α is the determined slope of the field.

7. The arrangement of claim 6 , wherein the device for determining the slope of the field comprises at least one of a slope sensor and the positioning system, the device consists of at least one antenna, and the device provides elevation information and a three-dimensional map of the field.

8. The arrangement of claim 6 , wherein the machine comprises a plurality of seeding or planting devices disposed laterally side by side across the working direction, and the control means is operable to separately control each of said plurality of seeding or planting devices to maintain a two-dimensional pattern of the planted seeds or plants.

9. The arrangement of claim 8 , wherein in addition to the spacing of adjacent seeds or plants along the working direction of the machine, at least one parameter of the pattern relates to the relative offset of seeds or plants in the working direction of the machine of two rows that are adjacent along the working direction of the machine.

10. The arrangement of claim 6 , wherein the control means is operable to control the machine as it goes over adjacent passes in the field to position the seeds or plants across the working direction in order to enable subsequent work in the field in a direction running at least one of across and diagonal to the working direction of the machine.
