    专利说明:

    The invention relates to a self-propelled harvesting machine, comprising: a chassis which is supported on the ground by means of drivable and steerable ground engagement means, a transfer device which is switched by an actuator between a transfer position for transferring crops onto a transport vehicle and a Transport position is movable; and a control device for controlling the actuator and driven crop processing means of the harvesting machine, which can be operated in a transport mode and a harvesting mode and in the harvesting mode enables the crop processing means to be switched on and the transfer device to be moved into the transfer position and, in the transport mode, the crop processing means and a Moving the transfer device into the transfer position prevented.
    PRIOR ART Self-propelled harvesting machines, such as forage harvesters or combine harvesters, comprise a chassis to which a harvesting header can be attached, means for processing the harvested crop and a loading device to transfer the processed harvested crop as required (from a grain tank of a combine) or continuously (in the case of a forage harvester ) overloaded onto a transport vehicle.
    The transfer device usually contains a screw or belt conveyor or is designed to be hollow to the one
    Post-accelerator to guide harvested crop brought to a sufficiently high speed on the transport vehicle.
    Since the drive power and possible throughputs of the harvesting machines and thus also the working widths of the harvesting headers are currently increasing, ever greater loading widths are required in order to load the harvested material from the harvesting machine onto the transport vehicle that is driving next to the harvesting head on the already harvested part of the field. This has the consequence that the transfer device during a transport trip, for which it is usually brought into a position extending backwards opposite to the direction of travel and locked there in a fixed position (see EP 1 405 555 A1), over the chassis of the harvesting machine extends backwards. With the currently required lengths of the transfer devices, however, there is the problem that a deviation given by the road traffic regulations is exceeded, i.e. Due to its length, the transfer device protrudes beyond a legally prescribed circle when the harvesting machine is cornering.
    It is known to divide the transfer device into two parts, of which the outer part can be pivoted or telescoped in relation to the inner part about the vertical axis (EP 1 330 948 A1) or about a transverse axis (DE 24 00 714 A1) ( DE 102 11 706 A1), but this also increases the mass of the transfer device and the costs incurred for it.
    Further proposals provide for the loading device to be supported on a harvesting header pulled behind the harvesting machine on a chassis by locking it to a storage device attached there and thus following the movements of the harvesting header when cornering (DE 10 2006 040 080 A1). To do this, however, it is necessary to relocate the cabin or dismantle the header so that it can be pulled behind the harvesting machine. In addition, it is necessary to deactivate the adjustment drive of the transfer device.
    Finally, it was proposed to couple the rotary position of the transfer device around the vertical axis during harvesting to the angular position of steerable wheels in order to simplify or automate the transfer process when a transport vehicle driving behind the harvesting machine is to be loaded (DE 198 48 127 A1). However, such a control of the transfer device in transport mode is not provided.
    Object The object on which the present invention is based is seen in improving a harvesting machine in such a way that the above-mentioned disadvantages are at least partially avoided.
    Solution According to the invention, this object is achieved by the teaching of patent claim 1, the further patent claims citing features that further develop the solution in an advantageous manner.
    A self-propelled harvesting machine, which can be, for example, a combine harvester with a unloading auger as a transfer device or a forage harvester with an ejection chute as transfer device, comprises a chassis that is supported on the ground by means of drivable and steerable ground engagement means, a transfer device which can be moved by an actuator between a transfer position for transferring crops onto a transport vehicle and a transport position; and a control device for controlling the actuator and driven crop processing means of the harvesting machine, which can be operated in a transport mode and a harvesting mode and in the harvesting mode enables the crop processing means to be switched on and the transfer device to be moved into the transfer position, and the crop processing means to be switched on and activated in the transport mode the transfer device prevented in the transfer position. The control device is set up (i.e. connected and programmed in such a way) to command the actuator in the transport mode depending on the steering direction of the harvesting machine in such a way that the harvesting machine with the loading device does not exceed a predetermined amount of deviation when cornering.
    In this way, it is prevented with little effort that the loading device, due to its length, protrudes beyond a legally prescribed circle when the harvesting machine is cornering, in that the actuator is actively controlled based on the steering direction of the harvesting machine in the transport mode.
    The transfer device can accordingly be rotated by the actuator when cornering around the vertical axis in the direction of the inside of the curve. There is also the possibility of telescoping the transfer device and thus shortening it when cornering in order to comply with the defined digging.
    The transfer device can extend backwards in a known manner in the transport position opposite to the direction of travel and / or positioned invariably in the transfer position (as is usual with a combine harvester) or manually adjustable by means of an operator interface or in a manner that enables automatic transfer by the actuator adjustable in position and there extend more or less transversely to the direction of travel.
    The ground engaging means may comprise steerable wheels and drivable wheels. In another embodiment, crawler tracks are used as ground engaging means, which can also be used for steering due to different drive speeds. The harvesting machine could also be designed as an articulated steering wheel. The control device can be connected to an operator input device for switching between the transport mode and the harvest mode (see DE 103 48 090 A1). Alternatively or additionally, it could be operable to automatically recognize the transport mode and / or harvest mode (cf. EP 1 405 555 A1).
    The transfer device can be supported in its transport position on a depositing device which allows the transfer device (30) to rotate about the vertical axis via the actuator (38). In another embodiment, no storage device is provided and the transfer device is held and supported in its transport position by an actuator for adjusting the transfer device about a horizontal axis at a distance from the chassis. The actuator used to adjust the transfer device around the horizontal axis can be connected to a damping device. Exemplary embodiment An exemplary embodiment of the invention is explained with the aid of the figures. 1 shows a schematic side view of a self-propelled harvesting machine in the transport mode, FIG. 2 shows a diagram of the interconnection of the control device of the harvesting machine of FIG. 1, FIG. 3 shows a plan view of the harvesting machine in the transport mode when driving straight ahead, and FIG
    4 shows a plan view of the harvesting machine in the transport mode when cornering. In FIG. 1, a self-propelled harvesting machine 10 in the form of a forage harvester is shown in a schematic side view. The forage harvester 10 is built on a chassis 12 which is carried by front driven wheels 14 and steerable rear wheels 16, which are optionally also driven. The harvesting machine 10 is operated from a driver's cab 18 from which a harvesting header 20 in the form of a pick-up can be viewed. By means of the header 20 picked up crop, z. B. grass or the like is fed via an intake conveyor 22 with pre-press rollers, which are arranged inside a intake housing 24 on the front of the harvesting machine 10, to a chopping drum 26 arranged below the driver's cab 18, which chops it into small pieces in cooperation with a shearbar 102 and it gives up a conveyor device 28 (after passing through a post-processing device with two processor rollers 32, 34, which are required for the maize harvest and which can be brought into a moved apart position for the grass harvest, as shown in FIG. 1, or removed). The crop leaves the harvesting machine 10 to a transport vehicle traveling alongside, following or coupled to it via a transfer device 30 in the form of an ejection spout. In the following, direction information, such as laterally, below and above, relate to the forward direction V of the harvesting machine 10, which runs to the right in FIG.
    The chopping drum 26 is driven from a belt pulley 48, which is connected to an internal combustion engine (not shown) via an angular gear, via a drive belt 50, which has a belt pulley 54 for driving the chopping drum 26 and a belt pulley 52 for driving the conveyor device 28. A grinding device 100 serves to grind the chopping knives of the chopping drum 26. In addition, a
    Metal detector 108 is provided in the lower, front feed roller, which may be used to stop the intake conveyor 22 quickly, and an operator input device 98 coupled to a control device 70 in the driver's cab 18. The operator input device 98 enables the chopping drum 26 to be switched on and off, including a An externally actuated clutch 36 (see FIG. 2) is inserted into the drive train between a drive motor of the forage harvester 10 and the chopping drum 26, which is controlled by the control device 70.
    The control device 70 also controls an actuator 38 for adjusting the transfer device 30 about the vertical axis, an actuator 40 for adjusting the transfer device 30 about a horizontal axis and an actuator 42 for adjusting the position of an ejection flap 44 of the discharge device 30. Another actuator (not shown ) can serve to telescope the discharge device 30 and be commanded by the control device 70. The control device 70 is also connected to feedback sensors (not shown) for the direct or indirect detection of the positions of the actuators 38, 40, 42. The actuators 38, 40, 42 are controlled in the harvesting mode by the control device 70 based on operator inputs that can be entered via the operator interface 98. It would also be possible to automate the control of the actuators 38 to 42 during the harvesting operation, e.g. based on image recognition (see, for example, DE 10 2012 211 001) or position recognition (see DE 10 2010 043 854 A1) of the transport vehicle. In normal harvesting operation, the loading device 30 is therefore more or less far to the left or right of the harvesting machine 10, in order to load the chopped crop onto a transport vehicle which is driving on the already harvested part of the field. When a field is opened, the transport vehicle can also be located behind the harvesting machine 10 and the transfer device 30 is then rotated backwards into the position shown in FIGS. 1 and 3, but raised in relation to FIG.
    The control device 70 is configured (constructed, interconnected and / or programmed) in such a way that it enables the harvesting machine 10 to be operated in a transport operating mode and a harvesting operating mode. The respective operating mode is selected by means of the operator input device 98, which comprises a so-called road / field operating switch. In the transport mode, neither the actuator 38 can move the transfer device 30 from its transport position shown in FIG. 1 into an transfer position extending to the left or right beyond the contours of the chassis 12 of the harvesting machine 10 for transferring the crop to the side, nor the actuator 40 the Swivel the transfer device 30 upwards from the transport position shown in FIG. 1 while the clutch 36 is still closed. In the harvesting mode, both the actuator 38 and the actuator 40 can move the transfer device 30 from its transport position shown in FIG. 1 into a transfer position extending to the left or right beyond the contours of the chassis 12 of the harvesting machine 10 for transferring the crop to the side Swivel the transfer device 30 upwards from the transport position shown in FIG. 1, and the clutch 36 is also closed. For this purpose, reference is made to the disclosure of DE 103 48 090 A1, the disclosure of which is incorporated into the present documents by reference. It would also be possible for the control device 70 to automatically recognize the harvesting and / or transport operating mode based on operator inputs or operating parameters of the harvesting machine 10, as described in EP 1 405 555 A1, the disclosure of which is incorporated by reference in the present documents.
    The harvesting machine 10 is steered by the rear wheels 16, using a steering wheel 60 which interacts with a (in particular mechanical, hydraulic and / or electrical) steering mechanism 62 which ultimately determines the angle of the rear wheels 16 about the vertical axis. A sensor 64 detects the steering angle specified by the steering wheel 60 or the steering angle set by the steering mechanism 62 and sends a corresponding signal to the control device 70. In another embodiment, the sensor 64 can detect the steering angle of the wheels 16. Automatic steering of the harvesting machine 10 can also be provided for the harvesting operation and possibly also the transport operation.
    In the transport mode of operation, there is the problem that the transfer device 30, due to its length, protrudes so far back beyond the contours of the chassis 12 that it protrudes beyond a legally prescribed circle when negotiating curves, i.e. exceeds a permissible deviation. To avoid this problem, it is provided that the control device 70 controls the actuator 38 in the transport mode based on the signals supplied to it by the sensor 64 with regard to the steering angle of the wheels 16 and, if necessary, rotates the transfer device 30 in the direction of the inside of the curve, as in FIG shown. In order to avoid unnecessary adjustment processes of the transfer device 30, an adjustment of the actuator 38 only takes place when the signal of the sensor 64 (or the detected steering angle of the wheels 16) depending on the desired steering angle becomes so large that the transfer device 30 without adjustment of the actuator 38 would extend beyond the given circle. The transfer device then initially remains in this position, even if the steering angle is reduced again. Only when the drive is then straight ahead will the actuator 38 move the transfer device 30 exactly to the rear, as shown in FIG. In another embodiment, the transfer device 30 follows the steering continuously. Should the transfer device 70 be telescopic, it can also be retracted while negotiating curves.
    In FIG. 1, a depositing device 96 is provided for the transfer device 30 in the transport position. When the harvesting machine 10 is in transport mode (and not in operation), the transfer device 30 is deposited on the depositing device 96, which enables the transfer device 30 resting on it to be adjusted by the
    Allows vertical axis. For this purpose, the storage device 96 and / or the transfer device 30 can be equipped with suitable sliding elements.
    It would also be conceivable to omit the depositing device 96 or to lift the transfer device 30 therefrom during transport operation. In this case, the transfer device 30 is only held by the actuator 40 in the raised position in which it is spaced from the chassis 12 of the harvesting machine 10. In order to avoid undesired vertical vibrations, a damping of the actuator 40 can be provided, as is described per se, for example, in EP 2 397 027 A2. In an embodiment in which the transfer device 30 is lifted from the depositing device 96 during the transport journey, the control device can command the actuator 40 to deposit the transfer device 30 on the depositing device 96, in particular when the harvesting machine 10 is switched off (or this lowering takes place automatically the pressure drop after switching off the internal combustion engine of the harvesting machine 10). The actuator 40 would accordingly lift the loading device 30 for the transport operation and the harvesting operation from the depositing device 96 and otherwise deposit it thereon.
