Richard Hey in Bernburg. Parallelführung für die Hackmesser von Hackmaschinen. Richard Hey in Bernburg. Parallel guidance for the chopping knives of chipping machines.

Patentiert im Deutschen Reiche vom 17. Dezember 1925 ab.Patented in the German Empire on December 17, 1925.

Bei Hackmaschinen, deren Hackmesser an Parallelogrammbebem befestigt sind, legt man bekanntlich. Wert darauf, daß die Gelenke der ParaJLdogrammhiebel gut und dauernd geführt werden, um ein seitliches Schwanken der Messer und damit eine Beschädigung der Pflanzenreihen sicher zu verhüten.In chopping machines whose chopping knives are attached to parallelogram bevels, one lays as is well known. It is important that the joints of the ParaJLdogrammhiebel are well and continuously guided to avoid sideways swaying of the knife and thus damage to the rows of plants safe to prevent.

Gegenstand der Erfindung ist eine diesem Erfordernis nachkommende Hackmesserparallelführung, die in ähnlicher Weise arbeitet wie die bekannten Parallelogrammhebel, diesen gegenüber jedoch den Vorteil größerer Einfachheit und außerdem die Fähigkeit besitzt, das seitliche Schwanken der Messer dauernd zu; verhindern. .The subject of the invention is a chopping knife parallel guide that meets this requirement, which works in a similar way to the well-known parallelogram levers, this one however, has the advantage of greater simplicity and also the ability to the sideways swaying of the knives steadily; impede. .

Die Zeichnung veranschaulicht eine Ausführ uingsform des Erfindungsgegenstandies.The drawing illustrates one embodiment of the subject matter of the invention.

Abb. ι ist eine Seitenansicht,Fig. Ι is a side view,

Abb. 2 eine Draufsicht der neuen Einrichtung. Fig. 2 is a plan view of the new facility.

Wie aus den. Abbildungen rsichtlich, ist das Hackmesser α an einem im Querschnitt U-förmijgen Eisenstück b angebracht. An dieses Eisenstück b sind mittels eines Querzapfens c Lenker d angelenkt, deren, nach vom gerichtete Enden durch einen Gefenkzapfen / mit einem am Querbalken g· befestigten Tragstück h schwinigbar verbunden sind. Der hintere Teil des Tragstückes h ist als kreisbogenförmige Kulisse / ausgebildet. In dieser Kulisse ist eine Rolle / geführt, welche auf einem im U-förmigen Eisenstück b festsitzenden Zapfen k lose gelagert ist. Der Krüm-'■ inungsradius r dler Kulisse / besitzt die gleiche Länge wie die die Mittelpunkte der Zapfen c und / verbindende Gerade, und der Mittelpunkt des mit diesem Krümmungsradius r As from the. In view of the figures, the chopping knife α is attached to a piece of iron b which is U-shaped in cross section. To this iron piece b are articulated by means of a transverse pin c links d , the ends of which are pivotably connected to the front end by a pivot pin / with a support piece h attached to the cross beam g. The rear part of the support piece h is designed as an arcuate gate /. In this setting, a roller / is guided, which is loosely mounted on a pin k that is firmly seated in the U-shaped iron piece b. The radius of curvature r dler coulisse / has the same length as the straight line connecting the centers of the pins c and /, and the center point of the radius of curvature r with this

ao beschriebenen Kreisbogens s entspricht dem vierten Eckpunkt des diurch die Lage der Zapfen k, c, f bestimmten Parallelogramms.The circular arc s described above corresponds to the fourth corner point of the parallelogram determined by the position of the pins k, c, f .

Die beschriebene Einrichtung sichert mit einfachen Mitteln die Parallelführung der Hackmesser in gleicher Weise wie bei Anwendung eines Parallelogrammhebelsystems, liefert aber zugleich den Vorteil, daß die Seitenflächen des 'die Kulisse / umfassenden U-förmigen Eisenstückes b das seitliche Schwanken des Hackmessers dauernd verhindern, also auch daran, wenm 'die Gelenkbolzen c, k, f schon abgenutzt sind.The device described ensures the parallel guidance of the chopping knife with simple means in the same way as when using a parallelogram lever system, but at the same time provides the advantage that the side surfaces of the 'the backdrop / U-shaped piece of iron b permanently prevent the lateral swaying of the chopping knife, so too see if the hinge pins c, k, f are already worn out.

Claims (1)

Patent-Anspruch:Patent claim: Parallelführung für die Hackmesser von Hackmaschinen, dadurch gekennzeichnet, daß jedes Hackmesser (ß) an einem im Querschnitt U-förmigen Eisenstück (b) angebracht ist, welches mittels Lenker (d) an ein am Querbalken (g) befestigtes Tragstück (h) angelenkt ist und mit seinen Seitenflächen eine mit dem Tragstück (A) fest verbundene, kreisbogenförmig gekrümmte Kulisse (i) umfaßt, in welcher eine auf einem durch die Seitenflächen dies U-förmigen Eisenstückes quer hindurchgesteckten Zapfen lose gelagerte Rolle (/) in Gemeinschaft mit den Lenkern (d) die Parallelführung des Hackmessers übernimmt. Parallel guide for the chopping knives of chopping machines, characterized in that each chopping knife (ß) is attached to an iron piece (b ) with a U-shaped cross-section, which is hinged by means of a link (d) to a support piece (h) attached to the crossbar (g) and with its side faces a crank (i ) firmly connected to the support piece (A), in which a roller (/) loosely mounted on a pin inserted transversely through the side faces of this U-shaped iron piece in common with the links ( d) takes over the parallel guidance of the chopping knife.
