Abstract

A header for harvesting stalk-like plants includes a number of gatherer assemblies arranged side by side for cutting off and conveying plants to a picking device arranged downstream of the gatherer assemblies. The picking device extends transversely to a direction of travel over the entire working width of at least one half of the header and includes a picking gap and stalk roll below the picking gap to separate fruits from the plants and to deliver them for a separate utilization.

First claim

What is claimed is:

1. A header for harvesting stalk-like plants comprising a number of gatherer assemblies arranged side by side for cutting off plants and conveying the plants to a picking device arranged downstream of the gatherer assemblies, the picking device extending transversely to a direction of travel, the picking device including a picking gap and a stalk roll below the picking gap to separate fruits from the plants and to deliver them for a separate utilization, wherein the picking gap of the picking device continuously extends over at least one half of the header, and the picking gap is formed between a rear end of a cover plate arranged above the gatherer assembly and a front end of a cross conveyor auger floor of a cross conveyor.

2. The header according to claim 1 , wherein the gatherer assemblies each comprise an infeed conveyor, the infeed conveyor rotating around a vertical axis and configured for cutting off the plants and for conveying the cut plants into an arc-shaped conveyor channel.

3. The header according to claim 2 , wherein an intermediate conveyor is provided downstream of the infeed conveyor, which intermediate conveyor rotates around a vertical axis and is configured to convey the plants along the conveyor channel and pass them to the picking device.

4. The header according to claim 3 , wherein the axis of rotation of the intermediate conveyor is offset sideways in relation to the rotary axis of the infeed conveyor.

5. The header according to claim 2 , wherein the infeed conveyor has a lower feed disc and an upper feed disc, the lower feed disc is equipped with outward-facing, protruding curved fingers, which cuts the plants in combination with a fixed counter knife below the lower feed disc, wherein the upper feed disc is coaxially arranged to the lower feed disc and provided with teeth moving over the conveyor channel.

6. The header according to claim 5 , wherein the fingers of the lower feed disc are provided at the trailing edge with upwardly directed webs.

7. The header according to claim 1 , wherein coils of the cross-conveyor auger are arranged above the picking gap.

8. The header according to claim 1 , further comprising cover hoods above the gatherer assemblies, which together with a cross conveyor auger floor form a recess.

9. The header according to claim 1 , wherein below the stalk rolls a stalk chopper and below the stalk chopper a separating plate is arranged, under which a stalk mulcher is arranged.

10. The header according to claim 1 , further comprising cover hoods above the gatherer assemblies, wherein adjacent cover hoods above the conveying channels form funnel-shaped recesses.

11. The header according to claim 8 , wherein adjacent cover hoods above the conveying channels form funnel-shaped recesses.

12. A header for harvesting stalk-like plants comprising a number of gatherer assemblies and an intermediate conveyor, the gatherer assemblies arranged side by side for cutting off plants and conveying the plants to a picking device arranged downstream of the gatherer assemblies, the picking device extending transversely to a direction of travel, the picking device including a picking gap and a stalk roll below the picking gap to separate fruits from the plants and to deliver them for a separate utilization, wherein the picking device extends over at least one half of the header, the gatherer assemblies each comprise an infeed conveyor, the infeed conveyor rotating around a vertical axis and configured for cutting off the plants and for conveying the cut plants into an arc-shaped conveyor channel, wherein at the rear of the intermediate conveyor a finger roller is arranged, which is rotatable around a rotational axis oriented transverse to the direction of travel and is provided with a finger arranged eccentric to the axis of rotation, which finger moves at least partially over the end area of the conveyor channel.

13. The header according to claim 12 , wherein the rotation speeds and numbers of the respective stalk-conveying elements of the infeed conveyor, the intermediate conveyor and the finger roller are dimensioned and synchronized in such a way, that the plants are conveyed at a constant speed over the entire length of the conveyor channel and that the finger of the finger roller acts with a plant exactly when it enters through action of the intermediate conveyor into the end area of the conveyor channel adjacent to the picking gap and the finger pulls the plant down to introduce the plant between the stalk rolls.

14. The header according to claim 12 , wherein an intermediate conveyor is provided downstream of the infeed conveyor, which intermediate conveyor rotates around a vertical axis and is configured to convey the plants along the conveyor channel and pass them to the picking device.

15. The header according to claim 14 , wherein the axis of rotation of the intermediate conveyor is offset sideways in relation to the rotary axis of the infeed conveyor.

16. The header according to claim 12 , wherein the infeed conveyor has a lower feed disc and an upper feed disc, the lower feed disc is equipped with outward-facing, protruding curved fingers, which cuts the plants in combination with a fixed counter knife below the lower feed disc, wherein the upper feed disc is coaxially arranged to the lower feed disc and provided with teeth moving over the conveyor channel.

17. The header according to claim 16 , wherein the fingers of the lower feed disc are provided at the trailing edge with upwardly directed webs.
