Definitions
- the present invention is related to agricultural harvesting machines, such as combine or forage harvesters, and in particular to the automatic coupling of a header to the feeder of the harvesting machine.
- the coupling of a header to the feeder or straw elevator of the combine is an operation involving a number of steps, several of which require manual intervention by the combine operator.
- the header is positioned on the ground and the operator drives the combine up to the header. Thereby first lowering the feeder and subsequently lifting the header up, for example by means of a hydraulic lifting system, until an interlocking contact is established, e.g. between a cradle on the feeder and an interlocking beam on the header.
- the feeder then further lifts up the header until the header rests against the front surface of the feeder.
- the operator needs to manually secure the header by a suitable locking mechanism, e.g.
- Patent publication EP-A-1884151 discloses a system comprising a movable gearbox and a telescopic jack shaft assembly for establishing an automatic connection of the drive shafts after the initial interlocking.
- Patent publication US-A-2008/0256914 is related to another system, involving a stationary gearbox secured to the feeder, and a telescopic jack shaft assembly.
- the present invention provides an agricultural machine comprising a feeder and a detachable header, the feeder comprising a means for lifting up the header from the ground, the lifting means comprising a cradle or similar lifting surface for supporting a beam or the like of the header, characterized in that: - the feeder comprises at least one or more rotatable cams located lower than the cradle, and actuating means for rotating the cams around an axis, wherein the cams and the actuating means are configured to : - maintain the header at a distance from the feeder, after the header has been lifted from the ground, by extending the cams towards a support surface of the header, - gradually reduce the distance between the feeder and the header, by rotating the cams away from the support surface of the header, the support surface with which the cams are in contact during at least a part of their rotation, - the feeder further comprises one or more hooks, configured to be able to rotate – actuated by the same actuating means - around the same axis as the cam
- the agricultural machine according to the invention offers the advantage that a reliable, automatic drive coupling becomes possible requiring only a minimal amount of actuators.
- the invention also provides a method for coupling a header to a feeder of an agricultural machine , comprising the steps of: - Driving the agricultural machine with the feeder attached at the front, up to the header; - Positioning cams on the feeder, located lower than the cradle, to maintain the header at a distance from the feeder; - Lowering the feeder until a cradle on the feeder is placed under a beam on the header and driving the agricultural machine a little bit forward; - Lifting up the header with the feeder, so that it hangs on to the cradle; - Rotating cams away from the header, thereby reducing the distance between the feeder and the header; - Simultaneously with the rotation of the cams, rotating the hooks around the same rotation axis as the cams, until the hooks grip a bar or pin located on the header, to thereby secure the header.

- Figure 5 is a blow-up of parts of the automatic coupling mechanism according to a preferred embodiment of the invention.
- Figures 6a to 6c show three different stages in the coupling action between the header and feeder drive shafts in a header and feeder combination according to the invention.
- Figure 1 shows a side view of a combine straw elevator or feeder 1 and a grain header 2 according to the present invention.
- the feeder 1 is operatively attached to the combine frame (not shown) in a known manner.
- the feeder comprises a lateral float frame 5 ( Figure 5), mounted at the front of the feeder, and arranged to be able to rotate with respect to the line of travel, to thereby allow lateral floatation of the header.
- the lateral float frame 5 can be a frame as known in the art.
- the invention is preferably related to a feeder comprising such a lateral float frame, but not limited thereto.
- the initial connection between the feeder 1 and the header 2 is established by interlocking the elevator cradle 3 of the feeder with an upper horizontal beam 4 of the header.
- Cradle 3 and beam 4 can be identical to parts in existing feeder/header combinations.
- the feeder of the invention comprises a hydraulic cylinder 10, attached to a fixed point 11 on the lateral float frame 5 of the feeder.
- the telescopic rod 12 of the cylinder 10 is shown in its most extended state in Figures 1 and 2.
- the movement of the rod 12 actuates the rotation of a lever 13 and a transverse shaft 14, to which a cam element 15 and a hook element 16 are attached, i.e. the hook and cam rotate together with shaft 14 and are fixed with respect to each other.
- the hook and cam extend from the shaft 14, in such a manner that their respective rotations combine to rotate the lower part of the header towards the feeder, while the hook moves forward to secure the header, by grabbing a pin or hook 18 (see detail in fig. 2b).
- the header is provided with abutments, such as plate elements 17, located in the same vertical plane as the cam elements 16.
- a hydraulic cylinder 10 and a lever 13 is arranged on one side of the feeder and the shaft 14 extends towards the other side, carrying a hook and a cam on both sides of the feeder. It is also possible to provide a cylinder and lever on both sides of the feeder.
- the hook/cam mechanism is cooperatively arranged with respect to an automatic drive shaft coupling mechanism 6, as shown in Figure 4.
- this drive shaft coupling mechanism is arranged to the left hand side of the feeder/header combination. It is the gradual movement of the header 2 towards the feeder 1 which is also the actuating movement for establishing the drive shaft coupling, as will be described in further detail hereafter.
- the drive shaft coupling mechanism 6 itself is coupled to the drive shaft 20 of the feeder, by means of a belt transmission.
- the rotation of the drive shaft is converted into rotation of a transversely oriented shaft in the gearbox 21.
- the rotation of the transversely oriented shaft in turn is transmitted onto an auxiliary shaft 22 by a pulley and belt transmission 23.
- the auxiliary shaft 22 finally drives the rotation of the universal joint 24 through auxiliary gearbox 25.
- the location of the auxiliary shaft 22 is fixed with respect to the feeder by a first support bracket 26.
- the coupling takes place by a pair of axial interlocking claws.
- the first claw 30 is mounted on the first axis of a 90° gearbox 33 attached to the header, the second axis of this gearbox being the header’s drive shaft 34, which is configured to drive the rotating parts of the header (not shown), and which is essentially parallel to the rotation axis of these rotating parts.
- the orientation of the drive shaft 34 and type of gearbox 33 could be different from the one shown in Figure 4, depending on the header type. What counts is that the coupling claw 30 facing the feeder is rotatably coupled to the header drive shaft, i.e. rotation of the coupling claw 30 causes rotation of the header drive shaft.
- the second claw 31 is mounted at the end of the coupling shaft 32, whose rotation is actuated by the universal joint 24.
- the first claw 30 gradually approaches the second claw 31, until both claws interact and the coupling is established, when the rotation of the coupling shaft is started.
- Figure 5 shows a blow-up of the different machine parts arranged according to the preferred embodiment between the universal joint 24 and the second claw 31, and configured to guide the coupling shaft 32 during the coupling action.
- the coupling shaft 32 is fixed to a cylindrical coupling element 40, itself coupled to the end of the universal joint 24.
- the coupling shaft 32 is furthermore arranged to be axially slidable with respect to a slider element 43, having a cylindrical front and rear portion 44, 45 and a cylindrical central portion 46 with a higher diameter than the side portions. While being axially slidable with respect to the slider element 46, the coupling shaft 32 and the slider element 43 are coupled rotationally.
- This coupling is established by a radial protrusion 55 on the coupling shaft, which fits into a corresponding slat in the slider element.
- the protrusion 55 may be a separate coupling element fitted between the shaft and the slider.
- the rear portion 44 of the slider element 43 is clamped inside the rotatable inner ring of a ball bearing 47, which is itself mounted in a bearing housing 48.
- Bearing housing 48 is mounted in slidable contact with a second support bracket 49, fixed to the lateral float frame of the feeder.
- the support bracket 49 comprises an opening 50 through which the coupling shaft 32 extends.
- the opening 50 has a diameter which is larger than the diameter of the coupling shaft 32.
- a helical spring 51 is mounted between the central cylindrical portion 46 of slider element 43, and between a support plate 52, fixed to shaft 32 and to which support plate the claw 31 is attached.
- the claw 31 is provided with a central protrusion 60, which serves to align the claws into a mutually corresponding radial position.
- the facing claw 30 is then provided with a corresponding depression (described further in this description).
- the bearing housing 48 is pushed against the face of the bracket 49 by the spring force exerted by the spring 51, and is thus able to slide with respect to the bracket while staying in contact with the bracket.
- the bracket 49 may be provided with blocking means for limiting the movement of the bearing housing and thus for limiting the radial movement of the coupling shaft 32 within the hole 50, and thus to avoid contact and damage.
- the resulting system allows for an axial movement of the coupling shaft 32 during coupling, as well as a limited radial movement, within the perimeter defined by the opening 50. These movements make it possible to establish the coupling automatically, as explained in detail hereafter, with reference to Figures 6a, 6b, 6c.
- the coupling takes place by rotating the header towards the feeder through actuation of the hydraulic cylinders 10 from an extended state (rod 12 telescopically extended) to a retracted state (rod 12 retracted).
- This movement starts from a starting position, shown in Figure 6a.
- the claw 30 connected to the header gearbox 33 gradually approaches the claw 31 attached to the coupling shaft 32.
- the coupling shaft 32 is not rotating. Due to the allowed radial displacement of the coupling shaft (within opening 50), the claws 30 and 31 can be brought to face each other, with the help of the central protrusion 60 on claw 31, which serves to align the claws into a mutually corresponding radial position (see Figure 6b) .
- the facing claw 30 is provided with a corresponding depression 61, arranged to receive the protrusion 60.
- the approach of the header towards the feeder further causes the spring 51 to be compressed, i.e. the coupling element 40 is pushed back with respect to the support bracket 49, and the coupling shaft slides with respect to slider element 43, see Figure 6c.
- Figures 6a-6c show an embodiment wherein the bracket 49 is provided with blocking means 62, to limit the movement of the bearing housing 48.
- the means for actuating the rotation of the cam/hook combinations may be any suitable actuating means, other than a hydraulic cylinder.
- the plate elements 17 can be any suitable abutment surface for the cams 15.
- the coupling of the universal joint 24 may take place without the belt transmission, but by directly coupling the joint 24 to the feeder drive shaft 20.
- the embodiment of Figure 4 is specifically designed for a feeder equipped with gearbox 21 arranged for actuating a lateral rotation axis, as known in existing machines. The presence of an automatic coupling does not require such a gearbox.
- the bracket 49 is fixed to the side of the feeder, and no lateral floatation is possible, hence no or very limited radial movement of the coupling shaft 32 must be provided for.
