Abstract

The main on-board computer adjusts guide actuators and signal controllers associated with spreader discs (8) and their hydraulic drive motors (9). A satellite positioning system (DGPS) establishes the spreader unit location, control data being generated accordingly, to control quantity and distribution. Control varies the spreader coverage quantity and width to each side, by means of the guides and disc speed(s).

Fig. 3 das Prinzip der Ausbringung anhand einer Bodenkarte. Fig. 3 shows the principle of application based on a soil map.

Der Schleuderdüngerstreuer 1 weist den Rahmen 2 und den Vorratsbehälter 3 auf. Über den Rahmen 2 ist der Schleuderstreuer 1 an den Dreipunktkuppler eines Ackerschleppers ankuppelbar. Dem Vorratsbehälter 3 sind Dosierorgane 4 zugeordnet. Diese Dosierorgane 4 sind als über Schieber 5 einstellbare Auslauföffnungen 6 ausgebildet. Die Schieber 5 werden über elektrische Stellelemente 7 eingestellt, so daß die Auslauföffnungen 6 in der für die jeweils auszubringende Düngermenge erforderliche Stellung einzustellen ist. Über die Dosierorgane 4 wird das sich im Vorratsbehälter 3 befindliche Streugut, beispielsweise Dünger, den unterhalb der Auslauföffnungen 6 angeordneten Schleuderscheiben 8 zugeführt. Diese Schleuderscheiben 8 werden über hydraulische Antriebsmotore 9 rotierend angetrieben. Diesen hydraulischen Antriebsmotoren 9 sind Regelelemente 10 zur Einstellung der Drehzahl der hydraulischen Antriebsmotore 9 und somit der Schleuderscheiben 8 zugeordnet. Sowohl den elektrischen Stellelementen 7 zur Einstellung der Dosierorgane 4 wie den Regelelementen 10 der hydraulischen Antriebsmotoren 9 der Schleuderscheiben 8 sind Sensorelemente zugeordnet, über welche die Ausbringmenge (Größe der Auslauföffnungen 6 und Stellung der Schieber 5) und die Drehzahl der Hydraulikmotoren 9 bzw. die Drehzahl der Schleuderscheiben 8 ermittelbar ist.The centrifugal fertilizer spreader 1 has the frame 2 and the storage container 3 . The centrifugal spreader 1 can be coupled to the three-point hitch of an agricultural tractor via the frame 2 . Dosing elements 4 are assigned to the storage container 3 . These metering elements 4 are designed as outlet openings 6 which can be adjusted via slide 5 . The slides 5 are adjusted via electrical actuating elements 7 , so that the outlet openings 6 are to be set in the position required for the amount of fertilizer to be applied in each case. The spreading material located in the storage container 3 , for example fertilizer, is fed via the metering elements 4 to the centrifugal disks 8 arranged below the outlet openings 6 . These centrifugal disks 8 are driven in rotation via hydraulic drive motors 9 . These hydraulic drive motors 9 are assigned control elements 10 for setting the speed of the hydraulic drive motors 9 and thus the centrifugal disks 8 . Both the electrical control elements 7 for setting the metering elements 4 and the control elements 10 of the hydraulic drive motors 9 of the centrifugal disks 8 are assigned sensor elements via which the application rate (size of the outlet openings 6 and position of the slide 5 ) and the speed of the hydraulic motors 9 or the speed the centrifugal discs 8 can be determined.

Die Regelelemente 10 der hydraulischen Antriebsmotore 9 und die Stellelemente 7 der Dosierorgane 4 sind über Leitungen mit einem Bordcomputer 11 verbunden. In dem Bordcomputer 11 ist eine Feldkarte des zu bedüngenden Feldes 12 mit der Kontur des Feldes 12 und der Nährstoffversorgung bzw. der jeweils auszubringenden Düngermenge standortspezifisch hinterlegt. Der Bordcomputer 11 arbeitet mit einem Standortbestimmungssystem, beispielsweise DGPS zusammen.The control elements 10 of the hydraulic drive motors 9 and the control elements 7 of the metering elements 4 are connected to an on-board computer 11 via lines. In the onboard computer 11 is a field map is stored the location specific to bedüngenden field 12 with the contour of the field 12 and the nutrient supply or respectively auszubringenden amount of fertilizer. The on-board computer 11 works together with a location determination system, for example DGPS.

Die Planung und Erstellung der in dem Bordcomputer 11 hinterlegten Karten und Daten über Kontur des Feldes 12, der Fahrspuren 13, auszubringende Menge je Standort und Arbeitsbreite je Standort werden auf einem Hof-PC erstellt und über eine geeignete Datenübertragungseinrichtung, beispielsweise Chipkarte etc. nach der Erstellung auf dem Bordcomputer 11 übertragen.The planning and creation of the maps and data stored in the on-board computer 11 about the contour of the field 12 , the lanes 13 , amount to be deployed per location and working width per location are created on a farm PC and via a suitable data transmission device, for example chip card etc. according to Creation transferred to the on-board computer 11 .

Die erstellten Daten weisen neben der auszubringenden Menge auch die jeweilige standortspezifische Arbeitsbreite des Schleuderstreuers 1 beinhaltend auf. In addition to the quantity to be spread, the data created also include the respective site-specific working width of the spreader 1 .

Desweiteren ist die Abhängigkeit zwischen der Drehzahl der Schleuderscheiben 8 bzw. den hydraulischen Antriebsmotoren 9 und der Wurfweite der Arbeitsbreite des Schleuderdüngerstreuers 1 in den Daten enthalten. Desweiteren sind in den Daten die Werte für das Grenzstreuen, Randstreuen, Normalstreuen und sonstige Gegebenheiten auf dem zu bestreuenden Feld 11 enthalten.Furthermore, the dependency between the speed of the centrifugal discs 8 or the hydraulic drive motors 9 and the throwing distance of the working width of the centrifugal fertilizer spreader 1 is included in the data. Furthermore, the data contain the values for border spreading, edge spreading, normal spreading and other conditions on field 11 to be spread .

Wenn die Arbeitsbreite bzw. Wurfweite durch Reduzierung der Drehzahl der hydraulischen Antriebsmotoren 9 der Schleuderscheiben 8, wie für die Fahrt an der Stelle entlang der Straße 14 oder des Gewässers 15 gegenüber der Darstellung des Streufächers 16 zurückgenommen werden muß, wie die Darstellung der Streufächer 16' und 16'' zeigt, wird gleichzeitig berücksichtigt, daß über die Stellelemente 7 die Dosierorgane 4 verändert werden müssen, damit bei einer Reduzierung der Arbeitsbreite auch die von dem Dosierorgan 4, welches der Schleuderscheibe 8, deren Drehzahl zur Reduzierung der Wurfweite reduziert ist, ausgebrachte Menge reduziert wird, damit pro Flächeneinheit die gewünschte Streugutmenge ausgebracht wird, siehe hierzu die Darstellung in Fig. 3.If the working width or throwing distance has to be reduced by reducing the speed of the hydraulic drive motors 9 of the centrifugal disks 8 , as for the travel along the road 14 or the water 15 compared to the representation of the spreading fan 16 , as is the case for the spreading fans 16 '. and 16 '', it is taken into account at the same time that the dosing elements 4 have to be changed via the adjusting elements 7 , so that when the working width is reduced, that of the dosing element 4 , which the centrifugal disc 8 , the speed of which is reduced to reduce the throwing distance, is applied Quantity is reduced so that the desired quantity of grit is spread per unit area, see the illustration in FIG. 3.
