Abstract

A harvesting attachment for whole plant harvesting includes a pick-up for picking up plants from a field, a first transverse conveyor belt and a second transverse conveyor belt for conveying the plants picked up transversely in a direction toward of a longitudinal center plane of the harvesting attachment, and two longitudinal conveyor belts which are arranged side-by-side and adjacent to the longitudinal center plane of the harvesting attachment and are set up to convey the plants entering from the transverse conveyor belts rearward to a rear discharge point of the harvesting attachment. The two longitudinal conveyor belts are inclined vertically upward in a direction toward the center plane at least over part of their length along the center plane.

First claim

What is claimed is:

1 . A harvesting attachment for attachment to a harvester machine, the harvester attachment comprising:
a supporting frame defining a longitudinal center plane; a pick-up supported by the supporting frame and operable to gather cut crop; a first transverse conveyor belt and a second transverse conveyor belt disposed on opposite sides of the longitudinal center plane, with each of the first transverse conveyor belt and the second transverse conveyor belt operable to convey the cut crop laterally inward toward the longitudinal center plane; a first longitudinal conveyor belt and a second longitudinal conveyor belt disposed on opposite sides of the longitudinal center plane, between the first transverse conveyor belt and the second transverse conveyor belt, with each of the first longitudinal conveyor belt and the second longitudinal conveyor belt operable to convey the cut crop longitudinally along the longitudinal center plane rearward relative to a direction of travel during operation; and wherein the first longitudinal conveyor belt and the second longitudinal conveyor belt are inclined laterally in a direction inward and upward relative to the longitudinal center plane over at least a portion of their respective length along the longitudinal center plane.

2 . The harvesting attachment set forth in claim 1 , wherein the first and second longitudinal conveyor belts each revolve around a respective front deflection roller and a rear deflection roller, and wherein an axis of rotation of the respective front deflection roller of the first and second longitudinal conveyor belts is inclined in a direction downward and outward from the longitudinal center plane.

3 . The harvesting attachment set forth in claim 2 , wherein the axis of rotation of the respective rear deflection roller of the first and second longitudinal conveyor belts has the same lateral inclination as the front deflection roller of the first and second longitudinal conveyor belts.

4 . The harvesting attachment set forth in claim 2 , wherein the axis of rotation of the respective rear deflection roller of the first and second longitudinal conveyor belts has a lesser lateral inclination as the front deflection roller of the first and second longitudinal conveyor belts.

5 . The harvesting attachment set forth in claim 2 , wherein the axis of rotation of the respective rear deflection roller of the first and second longitudinal conveyor belts is arranged substantially horizontally.

6 . The harvesting attachment set forth in claim 1 , further comprising a separating element arranged between the first and second longitudinal conveyor belts.

7 . The harvesting attachment set forth in claim 6 , wherein the separating element extends at least partially over a length of the first and second longitudinal conveyor belts along the longitudinal center plane.

8 . The harvesting attachment set forth in claim 6 , wherein the separating element extends vertically.

9 . The harvesting attachment set forth in claim 1 , wherein the pick-up includes mowing and intake devices for harvesting stalk-type plants.

10 . The harvesting attachment set forth in claim 9 , wherein the mowing and intake devices each have a lower cutting disk and conveying disks arranged thereabove, the conveying disks including recesses distributed around their circumference for receiving plants that are cut off by means of the cutting disks.
