  Dreschkorb für Getreidedreschmaschinen. 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 schienen g mit weiter Teilung der Löcher wie in Fig. 6 gegen solche mit enger Teilung wie in Fig. 7 ausgetauscht werden können ; diese beiden Figuren zeigen auch, dass die Stege zwischen den Löchern der Schienen um 90 Grad verdreht bzw. verwunden sind, um den Rost in sich zu versteifen. 



   Es ist sohin möglich, jede mit dem Dreschkorb gemäss der Erfindung ausgerüstete Dreschmaschine durch Austauschen des Rostes ohne besondere Umbauarbeiten aus einer Stiften-in eine Schlagleistendreschmaschine und umgekehrt umzuwandeln. Dabei kann bei Beschädigung einer Dreschleiste oder einer Korbschiene diese rasch an Ort und Stelle ausgewechselt werden. Desgleichen kann bei sehr brüchigem Getreide, wenn der Korb viel Kurzstroh durchlässt, dieses Übel durch Einsetzen enger gelochter Korbschienen beseitigt werden. Für die Fabrikation bringt die Erfindung den Vorteil, dass künftighin nur Maschinen mit neutralen Korbseitenteilen angefertigt werden brauchen, in die jeweils erst bei Abruf ein Rost für eine Schlagleisten-oder für eine Stiftendreschmaschine eingeschoben wird. Hiedurch wird die Fabrikation und Lagerhaltung verbilligt. 



   PATENT-ANSPRÜCHE :
1. Dreschkorb für Getreidedreschmaschinen, dadurch gekennzeichnet, dass die Dreschleisten   (e,     Cl)   und die Korbschienen (g) untereinander lösbar verbunden sind und einen selbständigen, sich selbst tragenden Rost bilden, der in die Korbseitenteile (a) eingeschoben und in diesen durch lösbare Quertraversen (b) festgehalten ist.

 rails g with a wide pitch of the holes as in FIG. 6 can be exchanged for those with a narrow pitch as in FIG. 7; These two figures also show that the webs between the holes in the rails are twisted or twisted by 90 degrees in order to stiffen the grate.



   It is thus possible to convert any threshing machine equipped with the threshing concave according to the invention from a pin threshing machine and vice versa by exchanging the grate without any special conversion work. If a threshing bar or basket rail is damaged, it can be quickly replaced on the spot. Likewise, in the case of very brittle grain, if the basket allows a lot of short straw to pass through, this evil can be eliminated by inserting narrow, perforated basket rails. For manufacturing, the invention has the advantage that in future only machines with neutral basket side parts will need to be manufactured, into which a grate for a blow bar or for a pin threshing machine is only inserted when requested. This makes manufacturing and storage cheaper.



   PATENT CLAIMS:
1. Threshing concave for grain threshing machines, characterized in that the threshing bars (e, Cl) and the concave rails (g) are releasably connected to one another and form an independent, self-supporting grate which is pushed into the basket side parts (a) and releasable in these Cross members (b) is held.
