Die Getreidesortierzylinder werden aus einem Stab gebildet, der schraubenförmig auf einem Zylindermantel aufgewickelt ist, so daß durch Zusammendrücken oder Auseinanderziehen der Durchgang zwischen den Stäben verkleinert oder vergrößert werden kann. Damit die Stäbe, welche den Mantel des Sortierzylinders bilden, gegeneinander sich nicht verschieben, werden sie auf der Innenseite mittels Schraubenfedern abgestützt, und es wird je ein Stab des Mantels mit je einem Gewindegang der Schraubenfeder fest verbunden. Dazu benutzt man bisher Bindedraht. Da aber die Stäbe des Sortierzylinders nur 2 mm auseinander stehen, so ist es umständlich und schwer, den Draht an jeder Stelle mehrmals hindurchzuziehen und die Bindung zwischen den Schraubenfedern und den Stäben fertigzustellen. Ist dies geschehen, dann wird durch Lötung die Verbindungsstelle gesichert. Das Zusammenbinden mit Draht hat indessen auch den Fehler, daß die Verbindungsstelle stark wird und infolgedessen die Stäbe des Sortierzylinders nicht nahe genug gegeneinander zusammengedrückt werden können.The grain sorting cylinders are formed from a rod that is helical is wound on a cylinder jacket, so that by squeezing or pulling apart the passage between the bars can be made smaller or larger. So that the rods that make up the mantle of the sorting cylinder, do not move against each other, they will be on the inside supported by coil springs, and there is a rod of the jacket with one each Thread of the helical spring firmly connected. Up to now, binding wire has been used for this purpose. But since the bars of the sorting cylinder are only 2 mm apart, it is cumbersome and difficult to pull the wire through several times at each point and the bond between the coil springs and to finish the bars. Once this is done, the connection point is made by soldering secured. However, tying it with wire also has the defect that the joint becomes strong and as a result the bars of the sorting cylinder are not compressed close enough to one another can be.

Um diesen Übelstand zu beseitigen, soll nun nach vorliegender Erfindung die Verbindungsnaht zwischen den einzelnen Stäben und den sie abstützenden Schraubenfedern mittels eines Blechstreifens anstatt eines Drahtes hergestellt werden.In order to eliminate this drawback, the connection seam should now be made according to the present invention between the individual rods and the helical springs that support them can be made using a sheet metal strip instead of a wire.

In den Zeichnungen ist die Erfindung veranschaulicht, und zwar stellen dar:The invention is illustrated in the drawings, namely:

wegen die Schraubenlinien nicht als solche gezeichnet sind, Fig. 2 und 4 zwei Ansichten, Fig. 3 und 5 zwei Schnitte für die Blechverbindung im größeren Maßstabe. Fig. 6 zeigt die Stirnansicht des Sortierzylinders.because the helical lines are not drawn as such, Figs. 2 and 4 are two views, 3 and 5 two sections for the sheet metal connection on a larger scale. Fig. 6 shows the front view of the sorting cylinder.

Der Sortierzylinder wird aus den Stäben a gebildet, welche schraubenförmig aufgewickelt und mittels der Schraubenfedern c, c abgestützt sind. Gewöhnlich werden acht bis zehn derartige Schraubenfedern zum Abstützen des Zylinders von innen benutzt.The sorting cylinder is formed from the rods a , which are wound in a helical shape and supported by means of the helical springs c, c . Usually eight to ten such coil springs are used to support the cylinder from the inside.

Zur Verbindung nun, welche zwischen den Stäben α und den einzelnen Gliedern c der Schraubenfedern b hergestellt werden muß, soll nach vorliegender Erfindung eine Blechklemme d benutzt werden. Nach Überbringen der Blechklemme d über die beiden zu verbindenden Glieder wird diese geschlossen und die Verbindungsstelle durch Lötung gesichert. Die Verbindung kann dabei eine zweifache sein, entweder so, daß die Enden der Blechklemme übereinander gelegt werden, entsprechend Fig. 2 und 3, oder daß sie nebeneinander gelegt werden, entsprechend Fig. 4 und 5. In dem letzteren Falle wird die Verbindungsstelle noch weniger verstärkt, wie in dem ersteren, und es ist dadurch möglich, die einzelnen Stäbe α des Sortierzylinders mehr aneinander zu bringen.For the connection now which has to be made between the rods α and the individual members c of the coil springs b , a sheet metal clamp d is to be used according to the present invention. After the sheet metal clamp d has been brought over the two links to be connected, it is closed and the connection point is secured by soldering. The connection can be twofold, either so that the ends of the sheet metal clamp are placed on top of each other, as shown in FIGS. 2 and 3, or that they are placed next to each other, as shown in FIGS. 4 and 5. In the latter case, the connection point is even less reinforced, as in the former, and it is thereby possible to bring the individual rods α of the sorting cylinder closer together.

Die Blechnaht kann entweder dadurch hergestellt werden, daß an jeder Verbindungsstelle eine Blechklammer über die beiden zu verbindenden Teile geschoben und. diese geschlossen wird, es kann aber auch ein Blechstreifen benutzt werden, der an der Verbindungsstelle so weit durchgezogen wird, daßThe sheet metal seam can either be produced in that at each connection point a sheet metal clamp pushed over the two parts to be connected and. this closed is, but it can also be used a sheet metal strip, which is at the connection point is pulled through so far that

Claims

a sufficiently long leg for the clamp connection on both sides is available. After this point has been cut open, those in this Way formed sheet metal clips closed.

Fig. 2 and 3 shows the Schlußverbindimg,

when the legs of the clamps are simply folded over one another.

4 and 5 show the connection at which brought the legs of the clamps side by side over the junction have been.

Figs. 7, 8 and 9 give intermediate stages for one type of fastening, Figs. 10, 11 and 12 for a second type of fastening of the sheet metal strip.

If a sheet metal strip is to be used to produce the sheet metal seam, this is inserted from the inside into the links c of the helical spring. Then it is pulled upwards at each of the connection points, as shown in FIG. 7. The eyelets that are formed are cut open and the sheet metal strip is held from the inside by a bolt, as shown in dotted lines, throughout this time. The cut eyelets, as shown in FIG. 8, are prevented from falling through by the bolt. The legs of these sheet metal clips formed in this way are then bent over the rods α , as shown in FIG. 9, so that they now connect the turns of the helical spring c with the rods α . Finally, the sheet metal clip is adapted by means of a pair of pliers \ the shape of the two connecting parts. If sheet metal clips are used for the connection, an abutment I must be inserted into the helical spring, which takes up the individual turns c of the helical spring and adapts to its cylindrical shape. The sheet metal clamps d are now, as shown in FIG. 10, pushed from above over the triangular bars so that the legs of the sheet metal clamps protrude into the recess of the abutment /. When the sheet metal clips are depressed, they are bent around the helical thread of the helical spring c , as shown in FIG. 11, following the path of the abutment. It is assumed that the legs, as shown in FIG. 4, run side by side and not on top of each other. Using a pair of pliers% of the connection of the sheet metal clip as Fig. 12 shows can be completed.

Grain sorting cylinder of the present type offer the particular advantage that one even finer types of grain and fruit can be sorted by means of the same, since one in is able to bring the bars close enough together.

Godfather ν T-A ν SPRU CH:

Connection of the bars of grain sorting cylinders with the inserted support springs, characterized in that the connection between each rod (a) and each thread (c) of the support springs (b) is made by means of a sheet metal bracket (d) and this connection is secured in a known manner by soldering , for the purpose of making production easier and keeping the slots as narrow as possible.
