9. AUGUST 1962AUGUST 9, 1962

Getreide - Trocknungsvorrichtungen für Mähdrescher sind bereits derart ausgebildet worden, die durch das Auspuffgas und den Kühler einer Verbrennungskraftmaschine abgeführte Wärme zu benutzen, z. B. die Kühler- und Abgaswärme des S Antriebsmotors eines Mähdreschers.Grain drying devices for combine harvesters have already been designed in such a way that to use heat dissipated by the exhaust gas and the cooler of an internal combustion engine, z. B. the cooler and exhaust heat of the S drive engine of a combine harvester.

Hier setzt die Erfindung ein. Sie löst die Aufgabe, dem Korntank bzw. der Abfüllvorrichtung des Mähdreschers eine kontinuierliche Getreidetrocknung vorzuschalten, welche weitgehend in die an sich vorhandene Fördervorrichtung für das Getreide eingegliedert ist und deren Bestandteile die bauliche Ausgestaltung dieser Fördereinrichtung nur unwesentlich verändern.This is where the invention comes in. It solves the task of the grain tank or the filling device of the combine harvester a continuous grain drying upstream, which largely in the per se existing conveying device for the grain is incorporated and its components the structural Change the design of this conveyor only insignificantly.

Die Erfindung beruht auf der Erkenntnis, daß bei dem üblichen Betrieb eines Mähdreschers und daher auch seiner Fördervorrichtungen der Wärmeinhalt des Auspuffgases und des Kühlers genügt, um feuchtes Korn im ununterbrochenen Dauerbetrieb im Zwangsumlauf so herunterzutrocknen, daß es gewohnlichen getreidetechnischen und handelsüblichen Ansprüchen genügt. Zur Lösung dieser Aufgabe besteht die neue Getreide-Trocknungsvorrichtung darin, daß dem Korntank bzw. der Abfüllvorrichtung eine aus Trockentrommeln bestehende Trocknungsanlage mit Zwangsumlauf vorgeschaltet ist, wobei die Auspuffgase zur Beheizung eines feststehenden Heizungsmantels benutzt werden, in dem die gegenüber den Auspuffgasen abgedichteten Trockentrommeln rotieren, während die aus dem Kühler austretende Warmluft dem Innern der Trockentrommeln unter Vermittlung eines Gebläses zugeführt wird.The invention is based on the knowledge that in the usual operation of a combine harvester and therefore Even its conveying devices, the heat content of the exhaust gas and the cooler is sufficient to keep it moist To dry down grain in uninterrupted continuous operation in forced circulation so that it becomes normal grain-related and customary demands. There is a solution to this problem the new grain drying device is that the grain tank or the filling device a A drying system consisting of drying drums with forced circulation is connected upstream, whereby the exhaust gases be used to heat a fixed heating jacket in which the opposite to the Exhaust gas-sealed drying drums rotate while the warm air exiting the cooler is fed to the interior of the drying drums by means of a fan.

Nach der Erfindung werden also die Auspuffgase zur mittelbaren Trocknung verwendet und die Warmluft aus dem Kühler zur unmittelbaren Trocknung des feuchten Getreides.According to the invention, the exhaust gases are used for indirect drying and the Warm air from the cooler for immediate drying of the moist grain.

Nach einer Verbesserung der Erfindung sind mit Transportschaufeln oder -schnecken beschickte, durch den Drescherantrieb rotierend betriebene Trockentrommeln von ruhenden Heizmänteln umgeben, denen Auspuffgase durch eine Leitung zugeführt werden, während ein Ventilator mittels einer Leitung die vom Motorkühler abgegebene Wärmemenge durch eine weitere Leitung dem Innern der Trockentrommeln zuführt.According to an improvement of the invention are loaded with transport blades or screws, by the thresher drive rotating drying drums surrounded by stationary heating jackets, to which exhaust gases are fed through a pipe, while a fan is fed through a pipe the amount of heat given off by the engine cooler through another line to the inside of the drying drums feeds.

Kornschnecke 3 wird das Korn der Trockentrommel 1 zugeführt. Die Trockentrommel 1 ist als rotierende Trommel mit Transportschaufeln 1 c ausgebildet und wird durch den Antrieb 4, der sich im Antriebskasten 5 befindet, in Umdrehungen versetzt. Die Trockentrommel 1 rotiert in einem feststehenden Heizmantel 6. Ein entsprechender Heizmantel 6 a umgibt auch den rotierenden Trockner 7. Durch die Kornratsche 8 wird das Korn aus der Trockentrommel 1 zu der Trockentrommel 7 geleitet. Die Trockentrommel 7 ist mit der Schnecke 18 versehen, die das aus der Trockentrommel 1 kommende Korn durch die Trockentrommel 7 führt. Auch die Trockentrommel 7 wird durch das Getriebe 4, das sich im Antriebskasten 5 befindet, angetrieben. Die Beheizung der feststehenden Heizmäntel 6 und 6 a erfolgt durch die Auspuffgase von dem Dieselmotor 9 aus. Durch die Rohrleitung 10 werden die Auspuffgase zur Eintrittsöffnung 11 der Heizmäntel 6 und 6 a geführt. Die Wege der Auspuffgase sind durch Pfeile A kenntlich gemacht, die der Heißluft durch Pfeile H. Bei 12 treten die Auspuffgase, nachdem sie die Heizmäntel durchströmt haben, ins Freie, ohne das Korn berührt zu haben. Der Dieselkühler (s. Fig. 1) ist mit 13 bezeichnet. Durch den Ventilator 14 wird die warme Luft, die im Dieselkühler 13 erwärmt wird, abgesaugt, und zwar durch die Leitung 15. Durch die Druckleitung 16 wird die warme Luft in die Trockentrommel eingeleitet. Die warme Luft durchströmt die beiden Trockentrommeln und tritt an der Stelle 17 aus. An der Stelle 19 treten aus dem Trockner 7 Korn und Luft aus.Grain screw 3, the grain is fed to the drying drum 1. The drying drum 1 is designed as a rotating drum with transport blades 1 c and is set in revolutions by the drive 4, which is located in the drive box 5. The drying drum 1 rotates in a stationary heating jacket 6. A corresponding heating jacket 6 a also surrounds the rotating dryer 7. The corn ratchet 8 guides the corn from the drying drum 1 to the drying drum 7. The drying drum 7 is provided with the screw 18, which guides the grain coming from the drying drum 1 through the drying drum 7. The drying drum 7 is also driven by the gear 4, which is located in the drive box 5. The stationary heating jackets 6 and 6 a are heated by the exhaust gases from the diesel engine 9. Through the pipe 10, the exhaust gases are guided to the inlet opening 11 of the heating jackets 6 and 6 a. The paths of the exhaust gases are indicated by arrows A , those of the hot air by arrows H. At 12, the exhaust gases enter the open air after they have flowed through the heating jackets without touching the grain. The diesel cooler (see FIG. 1) is denoted by 13. The warm air, which is heated in the diesel cooler 13, is sucked off by the fan 14, specifically through the line 15. The warm air is introduced into the drying drum through the pressure line 16. The warm air flows through the two drying drums and exits at point 17. At the point 19 emerge from the dryer 7 grain and air.

Die Wirkungsweise der Trockenvorrichtung ist folgende: Durch den Kornelevator 2 gelangt das feuchte Korn unter Vermittlung der Kornschnecke 3 zunächst in die rotierende Trockentrommel 1 undThe mode of operation of the drying device is as follows: The grain elevator 2 travels through the moist grain with the mediation of the grain screw 3 first in the rotating drying drum 1 and

dann durch die Kornrutsche 8 zum Trockner 7. Durch die Schnecke 18 wird das Korn, das nunmehr getrocknet ist, zum Korntank befördert und kann aus diesem entnommen werden.then through the grain chute 8 to the dryer 7. The screw 18 is the grain that is now is dry, transported to the grain tank and can be removed from there.

Eine derartige Trockenvorrichtung hat sich in der Praxis bestens bewährt. Die erzielten Erfolge führten zu einer Feuchtigkeitsminderung bis zu 4%.Such a drying device has proven itself very well in practice. The successes achieved led to a moisture reduction of up to 4%.
