Abstract
A device (16) for feeding granular material in an agricultural implement comprises an auger conveyor (163a, 163b), which is designed to feed the material, an agitator (162), and a drive device (167, 168a, 168b) for driving the agitator (162) and the auger conveyor (163a, 163b). The drive device (167, 168a, 168b) is adjustable between a first operating state, in which the agitator (162) is driven, but not the auger conveyor (163a, 163b), and a second operating state, in which both the agitator (162) and the auger conveyor (163a, 163b) are driven.
Claims14
An agricultural implement, comprising:
- an auger conveyor which is designed to feed granular material,
- an agitator, and
- a drive device for driving the agitator and the auger conveyor,
- wherein the auger conveyor and the agitator of the agricultural implement are rotatable about a common geometric axis,
- an upwardly concave bottom along which the granular material is transportable with the aid of the auger conveyor, and an outlet in said bottom, wherein the agitator is located at the outlet;
- the drive device is adjustable between:
- a first operating state, in which the agitator is driven, but not the auger conveyor, and
- a second operating state, in which both the agitator and the auger conveyor are driven,
- wherein the drive device comprises an actuator, which is configured to drive the agitator, and a coupling device, which is configured to cause the auger conveyor to be driven together with the agitator,
- wherein the coupling device is configured, in a first direction of rotation of the actuator, only to drive the agitator, such that the first operating state is obtained, and, in a second, opposite direction of rotation of the actuator, to drive both the agitator and the auger conveyor, such that the second operating state is obtained;
- and
- wherein the auger conveyor comprises first and second spaced apart auger conveyors with said agitator being disposed between the first and second auger conveyors, and wherein said outlet is disposed directly beneath said agitator and wherein said first and second auger conveyors are configured to convey granular material past the agitator and to the outlet.
Method of feeding granular material to ground over which an agricultural implement travels, wherein the agricultural implement comprises an agitator, an auger conveyor, and a drive device which is arranged to drive the agitator and the auger conveyor,
- which method comprises adjusting the agricultural implement between:
- a first operating state, in which the agitator is driven, but not the auger conveyor, and
- a second operating state, in which both the agitator and the auger conveyor are driven,
- wherein the adjustment is performed by changing a direction of rotation of a drive device, wherein the auger conveyor is activated with the aid of a coupling devices;
- and
- obtaining a higher speed of rotation in the second operating state than in the first operating state.
An agricultural implement, comprising:
- an auger conveyor which is designed to feed granular material,
- an agitator, and
- a drive device for driving the agitator and the auger conveyor,
- wherein the auger conveyor and the agitator of the agricultural implement are rotatable about a common geometric axis,
- an upwardly concave bottom along which the granular material is transportable with the aid of the auger conveyor, and an outlet in said bottom, wherein the agitator is located at the outlet;
- the drive device is adjustable between:
- a first operating state, in which the agitator is driven, but not the auger conveyor, and
- a second operating state, in which both the agitator and the auger conveyor are driven,
- wherein the drive device comprises an actuator, which is configured to drive the agitator, and a coupling device, which is configured to cause the auger conveyor to be driven together with the agitator,
- wherein the coupling device is configured, in a first direction of rotation of the actuator, only to drive the agitator, such that the first operating state is obtained, and, in a second, opposite direction of rotation of the actuator, to drive both the agitator and the auger conveyor, such that the second operating state is obtained;
- and
- wherein the drive device is configured to drive the agitator and auger conveyor at a higher speed in the second operating state than the speed at which the agitator is driven in the first operating state.
