Abstract

The invention pertains to a driver unit of a rotation-type conveyor with a finger retaining unit that is capable of being arranged in a rotatable manner on an axle segment, and with a finger that is secured by means of retaining devices to the finger retaining unit, and with restraining devices provided on the finger retaining unit for securing the part of the finger that is spatially separated from the finger retaining unit in the event of breakage of the finger. The retaining devices and the restraining devices are constructed in the form of one single component.

Claims

1. A driver unit of a rotation-type conveyor, comprising:

a finger retaining unit capable of being arranged in a rotatable manner on an axle segment;

a finger;

a retaining device for securing the finger to the finger retaining unit; and

a restraining device provided on said finger retaining unit for securing a part of the finger that is spatially separated from the finger retaining unit in the event of breakage of the finger;

wherein the retaining device and the restraining device are constructed in the form of a single component.

2. The driver unit in accordance with claim 1, wherein the retaining device is configured in the form of a cotter pin that extends through an opening, said opening passing through the finger and the finger retaining unit, and wherein said restraining device is configured as a segment that at least partially surrounds the part of the finger that is spatially separated from the finger retaining unit.

3. The driver unit in accordance with claim 1, wherein the finger is equipped with a predetermined breakage location between the part thereof that is adjacent to the finger retaining unit, and the part thereof that operates in conjunction with the restraining device.

4. The driver unit in accordance with claim 1, wherein the finger is equipped with a region, which projects outward relative to the rest of the finger, between the part thereof, which is adjacent to the finger retaining unit, and the part thereof that operates in conjunction with the restraining device.

5. The driver unit in accordance with claim 1, wherein the finger retaining unit is formed in the shape of a closable bearing element, and it has a finger retaining unit segment that configured to accommodate the finger, and wherein a sheath is provided that is equipped for surrounding the finger retaining unit segment of the bearing element and for closing the bearing element, and by the feature that the retaining devices secure the sheath to the finger retaining unit segment.

6. A rotary conveyor, comprising:

(1) a housing that is capable of being moved in rotation and having an opening;

(2) an axle segment that is arranged eccentrically in the housing; and

(3) a driver unit further comprising;

(a) a finger retaining unit arranged on the axle segment,

(b) a finger,

(c) a retaining device for securing the finger to the finger retaining unit; and

(d) a restraining device provided on said finger retaining unit for securing a part of the finger that is spatially separated from the finger retaining unit in the event of breakage of the finger;

(e) wherein the retaining device and the restraining device are constructed in the form of a single component

7. A cutting unit for a harvesting machine comprising:

(1) a frame comprising a base, a rear wall and two lateral walls;

(2) a winder mounted on the frame;

(3) a cutter bar mounted on the frame to cut crop material; and

(4) a spiral conveyor that extends transversely across the frame and further comprises,

(a) a housing that is capable of being moved in rotation and having an opening;

(b) an axle segment that is arranged eccentrically in the housing; and

(c) a driver unit further comprising

(i) a finger retaining unit arranged on the axle segment,

(ii) a finger,

(iii) a retaining device for securing the finger to the finger retaining unit; and

(iv) a restraining device provided on said finger retaining unit for securing a part of the finger that is spatially separated from the finger retaining unit in the event of breakage of the finger,

(v) wherein the retaining device and the restraining device are constructed in the form of a single component
