Description

Bei Dreschmaschinen gelangen die durch den Dreschkorb hindurchfallenden Körner mit den durch die Strohschüttler ausgesonderten Körnern, Kurzstroh und Spreu über das schwingende große Ährensieb zur ersten Reinigung. Es ist weiterhin bekannt, die durch den Dreschkorb hindurchfallenden Körner der ersten Reinigung zuzuführen, ohne daß diese das Ährensieb berühren und erst in der ersten Reinigung wieder mit den ungereinigten vereinigt werden. Bei diesen Anordnungen wird die erste Reinigung in jedem Falle stark überlastet.
Durch diese Erfindung wird nun eine wesentliche Entlastung der ersten Reinigung dadurch erreicht, daß vor dem großen Ährensieb ein Abfangsieb mit Führungsrinne zum Elevator angeordnet ist. Die durch den Dreschkorb hindurchfallenden, also schon vor-
In threshing machines, the grains falling through the concave, along with the grains, short straw and chaff separated by the straw shaker, are cleaned for the first time via the large vibrating ear sieve. It is also known to feed the grains falling through the concave to the first cleaning process without them touching the ear sieve and only being reunited with the uncleaned ones in the first cleaning process. With these arrangements, the first cleaning is heavily overloaded in any case.
With this invention, a significant relief of the first cleaning is achieved in that a collecting sieve with a guide channel to the elevator is arranged in front of the large ear sieve. Those falling through the concave, i.e. already in front of

ao gereinigten Körner berühren bei dieser Ausbildung die erste Reinigung nicht mehr, sondern gelangen direkt zum Elevator und von dort zum Entgranner oder der zweiten Reinigung. In this training, cleaned grains no longer touch the first cleaning, but rather get directly to the elevator and from there to the deburrer or the second cleaning.

Der Vorteil der Erfindung besteht darin, daß die durch den Dreschtrommelwind vorgereinigten Körner nicht mehr mit den übrigen ungereinigten zusammengelangen; hierdurch wird die erste Reinigung um mindestens 5o<y0 entlastet; Körner- und Zeitverluste, welche durch Siebverstopfungen entstehen, werden beseitigt, die Reinigung verbessert, die Leistung erhöht und die Bedienung vereinfacht.The advantage of the invention is that the grains pre-cleaned by the threshing drum wind no longer come together with the other uncleaned ones; this relieves the burden on the first cleaning by at least 50 <y 0; Grain and time losses caused by clogging of the sieve are eliminated, cleaning is improved, performance is increased and operation is simplified.

Der Erfindungsgegenstand ist in den Abb. 1 und 2 in schematischer Weise dargestellt.The subject of the invention is shown in Figs. 1 and 2 in a schematic manner.

Bei der Dreschmaschine nach der Erfindung ist der unter dem nicht dargestellten Dreschkorb befindliche Teil als Abfangsieb α ausgebildet. Dieses Sieb α bildet also die Verlängerung des bekannten großen Ährensiebes δ. Die durch die Trommel ausgeworfenen Körner gelangen für sich allein ohne Ähren durch diesen Siebteil a und werden durch die Führungsrinne c, d dem Sammeltrichtern zugeführt. Von hier gelangen sie in den Elevator/, der sie dem Entgranner oder der zweiten Reinigung direkt zuführt, ohne daß die vorgereinigten Körner mit den durch das Ährensieb b behandelten Körnern in der ersten Reinigung g zusammenkommen.In the threshing machine according to the invention, the part located under the concave, not shown, is designed as a trap screen α. This sieve α thus forms the extension of the known large ear sieve δ. The grains ejected by the drum pass by themselves without ears through this sieve part a and are fed to the collecting funnel through the guide trough c, d. From here they get into the elevator /, which feeds them directly to the deburrer or the second cleaning, without the pre-cleaned grains coming together with the grains treated by the ear sieve b in the first cleaning g .
