Description
Es sind Dreschkörbe für Dreschmaschinen bekannt, die aus einem gelochten Blech bestehen. Da bei dieser Einrichtung Dreschleisten fehlen, kann von einer Dreschwirkung kaum die Rede sein. Ferner sind aus gelochtem Blech bestehende Dreschkörbe bekannt, bei denen die Lochung durch Ausstanzen und Umbiegen der Lappen erzeugt wird. Da diese Körbe aus wirtschaftlichen und technischen Gründen nur aus dünnem Blech hergestellt werden können, so biegen sich die aufgebogenen Lappen sehr leicht zurück. Außerdem wirken die dünnen Lappen besonders nach eingetretenem Verschleiß alsThere are known concaves for threshing machines, which are made from a perforated sheet metal exist. As threshing bars are missing in this device, there may be a threshing effect hardly to be mentioned. Furthermore, threshing concaves made of perforated sheet metal are known, where the perforation is created by punching and bending the tabs. Because these baskets are made of economic and technical Reasons can only be made from thin sheet metal, the bent flaps bend back very easily. In addition, the thin flaps act as a
»5 Schneiden, und der Dreschkorb wirkt wie eine Reibe, so daß es nicht möglich ist, mit einem solchen Dreschkorb Langstroh zu erhalten. »5 cutting edges, and the concave works like a grater, so that it is not possible to obtain long straw with such a concave.
Der Dreschkorb gemäß der Erfindung istThe concave according to the invention is
•20 zwar auch aus einem Siebblech hergestellt, aber unterscheidet sich von den bekannten Körben dadurch, daß auf dem Blech die üblichen, über die ganze Breite des Dreschkorbes reichenden Schlagseiten aufgeschweißt sind, die kein Zerreiben und Zerreißen des Strohes hervorrufen. Durch die aufgeschweißten Schlagleisten wird eine große Festigkeit des Korbes erzielt, die noch durch von unten auf das Blech geschweißte Leisten, die senkrecht zu den Schlagleisten, d. h. in der Längsrichtung des Korbes liegen, erhöht werden kann. Dieses gehört jedoch nicht zur Erfindung.• 20 also made from a sieve plate, but differs from the known baskets in that the usual, are welded on over the entire width of the concave, which cause no rubbing and tearing of the straw. Through the welded Blow bars achieve a great strength of the basket, which is still through from below the sheet metal welded bars perpendicular to the blow bars, d. H. in the longitudinal direction of the basket can be increased. However, this is not part of the invention.
Die Fig. 1 und 2 der Zeichnung zeigen den Dreschkorb gemäß der Erfindung in zwei um 900 gegeneinander versetzten Schnitten.Figs. 1 and 2 of the drawing show the concave according to the invention in two 90 0 staggered sections.
