Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei dem durch das Haupt-Patent geschützten Schüttelwerk für Dreschmaschinen werden die Sammel- und Siebböden s direct und unmittelbar durch die Strohschüttler / m von der Strohschüttelwelle c aus hin- und herbewegt.In the shaking mechanism for threshing machines protected by the main patent, the collecting and sieving trays s are moved back and forth directly and immediately by the straw shaker / m from the straw shaking shaft c.

Es hat sich nun bei Anwendung dieser Construction auf Sammelböden gröfserer Maschinen der Uebelstand herausgestellt, dafs der durch das Beharrungsvermögen der Siebböden bei jedem Hubwechsel entstehende Stofs ungünstig auf die Strohschüttelkörper I m einwirkt, und zwar deshalb, weil die Angriffstellen der Kraft, die Punkte i und f bezw. k und e in der Patentschrift Nr. 53822, aufserhalb der Richtung der Kraftäufserung liegen und dadurch, bei jedem Hubwechsel in den Körpern m I der Schüttler ein Biegungs- und Drehmoment in wechselnder Richtung erzeugen, durch welches die Haltbarkeit derselben beeinträchtigt wird.When this construction is used on collecting trays of larger machines, the disadvantage has now been found that the substance created by the inertia of the sieve trays with every stroke change has an unfavorable effect on the straw shaking bodies I m , namely because the points of application of the force, the points i and f or k and e in patent specification no. 53822, lie above the direction of force accumulation and thereby generate a bending and torque in alternating directions with each stroke change in the bodies m I , which affects the durability of the same.

Um das Dreh- und Biegungsmoment zu beseitigen, sind nun in vorliegender Neuerung die Hebelarme q und r in der Patentschrift Nr. 53822 über i bezw. k hinaus bis 0 und ρ verlängert und mit den Punkten d dY aufserdem in eine gerade Linie verlegt, so dafs die nunmehr geschaffenen starren Verbindungsstangen dio und dx kp der vorliegenden Construction bei jedem Hubwechsel fast nur auf Zug- und Druckfestigkeit in Anspruch genommen werden. Die Bewegung und Construction des Armschüttelwerkes bleibt im übrigen dieselbe und unverändert.To eliminate the rotational and bending moment, the lever arms are now in the present innovation q and r BEZW in the patent no. 53822 on i. k extended to 0 and ρ and also laid in a straight line with the points dd Y , so that the rigid connecting rods dio and d x kp of the present construction are almost exclusively used for tensile and compressive strength at every stroke change. The movement and construction of the arm-shaking mechanism remains otherwise the same and unchanged.

Claims (1)

Patent-Anspruch:Patent claim: Eine Ausführungsform des durch Patent Nr. 53822 geschützten Armschüttelwerkes für Dreschmaschinen, dadurch gekennzeichnet, dafs die Hebelarme r und q des Haupt-Patentes drehbar mit den Querträgern i k verbunden und zu Zugstangen d ο und dx ρ verlängert sind, welche unmittelbar an den nicht mehr mit dem Strohschüttler verbundenen Siebböden s angreifen, zum Zweck, bei der Umkehr der Bewegung der Siebböden die Stöfse auf die Strohschüttelkörper zu vermeiden.An embodiment of the General Patent rotatably connected to the cross beams ik and ο to tie rods D and D x ρ extended the through Pat. No. 53822 protected Armschüttelwerkes for threshing machines, characterized in that the lever arms DAF r and q, which directly to the no longer with the straw walkers associated trays s attack, for the purpose, in the reversal of movement of the sieve trays to avoid the percussions on the Strohschüttelkörper.
