摘要:
A control system (100) is disclosed for an agricultural implement (40), such as an agricultural sprayer, used to dispense a product to the ground wherein the dispensing units (10) for the product are provided with control valves (14) that can reduce the flow rate of product through selected dispensing units (10) to zero. By controlling the rate of flow through the dispensing units (10), overlap of the application of the product to the ground can be substantially eliminated. In alternative embodiments of the invention, the control system (100) can receive data from a remote source, such as a central controller (57) or another implement (40) operating in the field, to define where the product needs to be applied to the ground. The application of the product can also be controlled through or in conjunction with a prescription map. Preferably, each dispensing unit (10) is provided with a control valve (11) operable associated with the control system (100) so that each dispensing unit (10) can be independently controlled to provide a variable flow rate of the product to the ground.
摘要:
Bodenbearbeitungsgerät mit einem Geräterahmen, der sich mittels vorderer und hinterer auf dem Boden abrollender und in Fahrtrichtung gesehen beabstandet zueinander angeordneter Laufräder und/oder Walzen abgestützt und die an dem Geräterahmen angeordneten Bodenbearbeitungswerkzeuge in ihrer Arbeitstiefe in den Boden führen, wobei die Bodenbearbeitungswerkzeuge gegenüber dem Geräterahmen in aufrechter Richtung verstellbar angeordnet sind. Um das Bodenbearbeitungsgerät hinsichtlich seiner Arbeitsqualität zu verbessern, ist vorgesehen, dass in der elektronischen Steuer- und/oder Regeleinrichtung eine Feldkarte mit ortsspezifischen Angaben zur Eindringtiefe der Bodenbearbeitungswerkzeuge im Boden abgespeichert ist, dass aufgrund der abgespeicherten Daten die Einstellmittel zwecks Einstellung der Eindringtiefe ortsspezifisch angesteuert werden, dass die Bedieneinheit der elektronischen Steuer- und Regeleinrichtung zumindest ein manuell betätigbares Element aufweist, mittels welchem die abgespeicherten Daten übersteuer- und/oder überregelbar sind, so dass aufgrund des manuellen Eingriffes die aufgrund der abgespeicherten Daten eingestellte Arbeitstiefe der Bodenbearbeitungswerkzeuge veränderbar und/oder übersteuerbar ist.
摘要:
Die Erfindung bezieht sich auf eine Einrichtung zur Positionsbestimmung eines landwirtschaftlichen Arbeitsfahrzeugs (10), mit einer Auswertungseinrichtung (46), die mit einem ersten Positionssignal und einem zweiten Positionssignal beaufschlagt wird und zur Berechnung der jeweiligen Position des Arbeitsfahrzeugs (10) eingerichtet ist, wobei das erste Positionssignal und das zweite Positionssignal jeweils eine Information über die derzeitige Position des Arbeitsfahrzeugs (10) enthalten, und der Auswertungseinrichtung (46) eine Qualitätsinformation über die Qualität eines der Positionssignale vorliegt. Es wird vorgeschlagen, dass die Auswertungseinrichtung (46) bei der Berechnung der Position das erste Positionssignal und das zweite Positionssignal entsprechend der Qualitätsinformation gewichtet berücksichtigt.
摘要:
An optical soil survey device to survey the optical characteristics of a given underground soil, a soil survey device to survey the soil, a soil survey system and a mobile soil survey vehicle to survey the soil are disclosed. The disclosed devices and systems may be used to survey the characteristics of a given soil for agricultural purposes. This survey can be carried out without experiencing significant resistance from the soil. A plow-shaped optical soil survey device may be provided with a plow-shaped main unit, whose forward extremity turns up soil; a frame, which supports the sensor and connects a tractor and a main unit; a spectrometer, which is mounted on the frame; a wheel, which surveys the depth of the furrow and is connected to the main unit via an arm; and a survey control unit, which is mounted on the tractor.

A control device (14) is provided for controlling the operation of boom-mounted agricultural equipment having a plurality of individually-operable boom sections (20). The control device (14) includes a switching device (28) for switching individual boom sections on and off, a timing device (26) connected to the switching device (28) for controlling the timing of the switching operations, and an input device (24) connected to the timing device (26) for entering the data required to determine the timing of the switching operations, and for initiating operation of the device.
摘要:
An agricultural harvesting machine (10) (harvester) is automatically controlled and steered so as to completely harvest all crop in a field. A Global Positioning System (54) (GPS) and an Inertial Navigation System (56) provide data regarding the position and orientation of the harvester in a field. A Field Coverage Planner (116) constructs a field coverage plan which defines a path for the harvester (10) to follow in cutting crop from a field. Video images of the field in front of the harvester are derived alternately from two video cameras (42, 44) mounted on opposite sides of the harvester. The video images are processed in a Video Processing Computer (48) to detect the crop line (16, 16') between cut and uncut crop and generate steering signals for steering the harvester along the crop line. Video images are also processed to detect the end of a row (18) at the end of a field and supply a measure of the distance to the end of the row. When the end of a row is reached, the harvester (10) executes a 180 DEG spin turn and traverses the field in the opposite direction.
摘要:
A distributed network product applicator control system uses object-oriented software, windows interfacing, distributed network technology and Echelon LonWorks network technology allowing a fixed loop system to be expanded by adding a multiplicity of additional loops to the system with only a transparent effect on the whole. Each loop is independent thereby allowing application of a product in response to an application map for an area which is unique only to that particular loop.
摘要:
The present invention relates to an agricultural machine (1), which has front tool elements (14) with vertically symmetrical earth-working tools, such as discs, which are arranged in predetermined positions relative to the driving direction of the machine, and rear tool elements (15) in the form of roller elements for forming a coherent roller. The disc-supporting tool is pivotable in such a way that the long side of the front unit facing towards the driving direction can be directed away from the driving direction, and vice versa, so that essentially two-mirror images of the machine along a central plane in the driving and longitudinal direction are achieved for the purpose of giving an adjusted and even working of the ground.
