摘要:
The present invention is related to a method for harvesting crops from a field and to a method for working a field by towing an apparatus such as a tilling apparatus, wherein the methods of the invention employ manned and unmanned vehicles. The operation and movement of the unmanned vehicles is controlled by the drivers of the manned vehicles which are continuously in the vicinity of the unmanned vehicles. The harvesting method involves at least the driver of a harvesting vehicle such as a combine harvester and the driver of a crop collecting vehicle such as a truck, wherein the drivers control the operation of one or more unmanned crop carts, operated to receive harvested crops from the harvesting vehicle during a harvesting phase and deliver harvested crop to the crop collecting vehicle during a subsequent delivery phase The control effected by the driver of the harvesting vehicle and the driver of the collecting vehicle is such that each driver is capable of visually inspecting the crop cart's operation during the totality of the harvesting and delivery phases respectively. The invention is equally related to a method for working an agricultural field wherein an agricultural apparatus, such as a tillage apparatus, is towed through the field, by one or more unmanned vehicles, while the operation of the unmanned vehicles is controlled by the operator of a manned vehicle that is moving along with the unmanned vehicles through the field.

A forage harvester including a header for picking up a swath from a ground surface. The header includes a first and a second distance sensor adapted to measure a sensor-to-target distance respectively along a first and second sensor axis. The first distance sensor is mounted at a first lateral end of the header, and the second distance sensor is mounted at a second lateral end of the header. The first and second distance sensors are positioned such that, when the forage harvester is placed on an even ground surface, the first sensor axis crosses the second sensor axis before reaching the even ground surface in front of the harvester.

An agricultural harvester including a sensor for measuring a position of an object in surroundings of the harvester. The sensor is connected to a processor for defining at least two different danger zones respectively corresponding to at least two different sets of harvester driving parameter values. The processor can determine actual harvester driving parameter values, and the processor can compare the actual harvester driving parameter values with the different sets to select a matching set and to select a corresponding one of the danger zones. The processor outputs a warning signal if the position is in the corresponding danger zone.

A controller (12) is provided for an unloading system, comprising an unloading apparatus (1) and a container (4), which are movable relative to each other. The unloading apparatus (1) is configured to direct material (3, 9) to the container (4). The controller (12) is configured to determine a build-up speed of the material (3, 9) in the container (4); in accordance with the determined build-up speed, determine a rate of change to be applied when setting an attribute of the unloading apparatus (1) and/or container (4); and set an attribute of the unloading apparatus (1) and/or container (4) in accordance with the determined rate of change in order to direct the material (3,9) from the unloading apparatus (1) to the container (4).

A controller (12) for a movable unloading apparatus (1) of an agricultural harvesting machine, wherein the movable unloading apparatus (1) is configured to direct crop material (3) from the agricultural harvesting machine to a container (4) driven in the vicinity of the agricultural harvesting machine, and wherein the controller is configured to receive image data representative of a stream (3) of crop material as it passes from the unloading apparatus (1) to the container (4); process the image data in order to determine a shape of the stream (3) of crop material in the image data; and set an attribute of the unloading apparatus (1) in accordance with the determined shape of the stream of crop material in order to direct the crop material (3) from the unloading apparatus (1) to the container (4).
摘要:
A cleaning section of an agricultural harvester. The cleaning section including a sieve, a plurality of load sensors, and a sieve slope compensating system. The sieve is positioned in the harvester to receive crop material from a threshing section. The plurality of load sensors are coupled to the sieve. The load sensors are configured to produce signals representative of a distributed load of the crop material on the sieve. The sieve slope compensating system is configured to tilt or side shake the sieve dependent upon the signals.

An agricultural combine including a residue spreading system that is steerable to influence distribution of the residue spreading system. The combine is provided with a sensor provided for emitting a wave signal through the residue when the combine is spreading the residue. The sensor is configured to measure reflections of the signal from a first zone of the residue and from a second zone of the residue. The spreading system is steered based on the reflections. The wave signal has a wavelength that is larger than 0.001 mm and that is smaller than 50 mm.
