Abstract

A driving device of a conveyor device such as an intake finger assembly of an auger of a harvesting device includes a feeder aid disposed in an interior of the conveyor device, a swivel bearing for supporting the feeder aid on a control shaft, a first fastening section assigned to the swivel bearing, and a second fastening section. The second fastening section is disposed at a distance from the first fastening section, between which a predetermined breaking point is disposed on the feeder aid. The first fastening section and the second fastening section are interconnected by a resiliently elastic connecting element.

Claims

1. A driving device (22) of a conveyor device (4), comprising;

a feeder aid (11) disposed in an interior of the conveyor device (4),

a swivel bearing (15) for supporting the feeder aid (11) on a control shaft (12),

a first fastening section (16) assigned to the swivel bearing (15), and

a second fastening section (18), which is disposed at a distance from the first fastening section (16), between which a predetermined breaking point (21) is disposed on the feeder aid (11),

wherein the first fastening section (16) and the second fastening section (18) are interconnected by a resiliently elastic connecting element (17), which embodies a helical tension spring (24).

2. The driving device (22) according to claim 1, wherein a spring travel of the connecting element (17, 24) is limited by a limiting element (19).

3. The driving device (22) according to claim 2, wherein the limiting element (19) has a length that corresponds at least to a length of the section that is effective for a deflection of the connecting element (17, 24).

4. The driving device (22) according to claim 2, wherein the limiting element (19) extends substantially parallel to the connecting element (17, 24).

5. The driving device (22) according to claim 2, wherein the limiting element (19) encloses spring coils (26) of the helical tension spring (24), at least in sections.

6. The driving device (22) according to claim 2, wherein the limiting element (19) has a substantially C-shaped contour.

7. The driving device (22) according to claim 2, wherein the limiting element (19) has a substantially oval, annular contour.

8. The driving device (22) according to claim 1, wherein the second fastening section (18) is an annular disk disposed coaxially to the feeder aid (11).

9. The driving device (22) according to claim 1, wherein the conveyor device (4) is an intake finger assembly of an auger of a harvesting device.

10. An agricultural harvesting machine, comprising a conveying device (4) configured with a driving device (22), the driving device (22) comprising:

a feeder aid (11) disposed in an interior of the conveyor device (4),

a swivel bearing (15) for supporting the feeder aid (11) on a control shaft (12),

a first fastening section (16) assigned to the swivel bearing (15), and

a second fastening section (18), which is disposed at a distance from the first fastening section (16), between which a predetermined breaking point (21) is disposed on the feeder aid (11),

wherein the first fastening section (16) and the second fastening section (18) are interconnected by a resiliently elastic connecting element (17), which embodies a helical tension spring (24).
