Description

Ρλτεν τ-Anspruch:Ρλτεν τ-claim:

Unteres Putzwerk für Dreschmaschinen, bei dem die nicht ausgedroschenen Ähren durch einen Exhaustor einer nochmaligen Behandlung zugeführt werden, dadurch gekennzeichnet, daß dieser Exhaustor in an sich bekannter Weise als Dreschtrommel ausgebildet ist und die in ihm gedroschenen Ähren wieder dem ' Siebkasten zuführt. ' 'Lower cleaning unit for threshing machines, in which the ears that have not been threshed out through an exhaustor are repeated Treatment are supplied, characterized in that this Exhaustor is designed in a manner known per se as a threshing drum and the ears threshed in it are returned to the ' Sieve box feeds.

Bei Stiftendreschmaschinen mit Reinigung ist es üblich, die vom Ährensieb kommenden abgezwickten und unausgedroschenen Ähren in einem Korb aufzufangen, um sie zum nochmaligen Durchdrusch in die Dreschtrommel zu schütten, oder wie bei bekannten amerikanischen Maschinen, dieses vermittels eines endlosen Förderers zu bewerkstelligen.
, Dieses nochmalige Dreschen durch die ίο Dreschtrommel hat jedoch den Nachteil, daß die abgezwickten und dünneren Ähren zum größten Teil wieder durch die Trommel gehen, ohne ausgedroschen zu werden, da der Durchgang für das Dreschen voller Ähren - 15 eingestellt ist. Ein engeres Stellen während ' des Betriebes hat das Zerschlagen vieler Körner zur Folge.
In pen threshing machines with cleaning, it is customary to collect the nipped and unthrown ears of corn coming from the ear sieve in a basket in order to pour them into the threshing drum for further threshing, or, as with known American machines, to do this by means of an endless conveyor.
However, this repeated threshing by the threshing drum has the disadvantage that the pinched and thinner ears go through the drum for the most part without being threshed, since the passage for threshing full ears - 15 is set. Closer positioning during operation results in the breaking up of many grains.
Die Erfindung hat den Zweck, diesen Nach- | teil aufzuheben und diese nochmalige Bev»o handlung der Ähren unabhängig von der Dreschtrommel auszuführen. Sie erreicht es dadurch, daß es die vom Ährensieb im Siebkasten übergeblasenen Ährenteile durch einen Exhaustor ansaugt, in diesem ausdrischt »5 und wieder dem unteren Putzwerk zuführt.The invention has the purpose of this post | cancel part and these repeated Be execute v »o treatment of the ears, regardless of the threshing drum. It achieves it by sucking in the ear parts blown over by the ear sieve in the sieve box through an exhaustor, threshing it out in this and then feeding it back to the lower cleaning unit. Fig. ι zeigt die Erfindung im Längsschnitt und Fig. 2 im Querschnitt.Fig. Ι shows the invention in longitudinal section and Fig. 2 in cross section. Die vom Ährensieb «kommenden abgezwickten Ährenteile werden durch das verstellbare Brett b aufgefangen, und fallen in den seitlich abführenden Kanäle, dessen Boden als Sieb ausgebildet ist. Durch dieses fallen die ebenfalls übergeblasenen, leichten Körner, sowie die durch die Bewegung des Siebkastens aus den Ähren sich lösenden Körner auf den Boden cf und von hier in den Auslauf e. The pinched ear parts coming from the ear sieve are caught by the adjustable board b and fall into the laterally discharging channels, the bottom of which is designed as a sieve. Through this, the light grains, which are also blown over, as well as the grains loosening from the ears due to the movement of the sieve box, fall to the bottom cf and from here into the outlet e. Die über den Siebboden c gleitenden Ähren 'werden jedoch von dem Exhaustor g angesaugt, in diesem von den am Rande der Flügel h befestigten Stiften oder Zähnen i erfaßt und durch das mit einigen Reihen gleichartiger Stifte oder Zähne besetzten Segment k hindurchgerissen. Hierbei werden die Ähren von sämtlichen Körriern befreit und beide durch den Windkanal in wieder in den Siebkasten zur nochmaligen Reinigung geblasen.The ears' sliding over the sieve bottom c , however, are sucked in by the exhaustor g , grasped by the pins or teeth i attached to the edge of the blades h and torn through the segment k , which is occupied by several rows of similar pins or teeth. Here, the ears are exempt from all Körriern and both blown by the wind tunnel back into the screen box for repeated cleaning. Um den Durchgang zwischen den Zähnen oder Stiften verstellen zu können, ist das Segment fe, in bekannter Weise, beweglich angeordnet und durch die Stellschraube I regelbar. ' >' ■·.■ f;;v: '■ Vx':-.': ■· <-■■'■■ ' . ■In order to be able to adjust the passage between the teeth or pins, the segment fe is movably arranged in a known manner and can be regulated by the adjusting screw I.
