Description

Von einer guten Hackmaschine verlangt man, daß der Schnittwinkel der Hackmesser ohne großen Zeitverlust bei der Hackarbeit verstellt werden kann. Es sind Vorrichtungen bekannt geworden, bei denen dieses dadurch erreicht werden soll, daß die Hackrahmenschienen, an welchen die Parallelogramme befestigt sind, dem gewünschten Schnittwinkel entsprechend gedreht werden, indem ίο der Hackrahmen mehr oder weniger schräg gestellt oder die Schiene gedreht und in Höhenrichtung verstellt wird. Dieses hat bei zweireihigen Hackmaschinen aber den Nachteil, daß die vorderen Parallelogramme tiefer zu stehen kommen als .die hinteren. Da bei der Arbeit durch die entstehende Zugwirkung die Verbindungsteile der Parallelogramme sich parallel zum Erdboden einstellen, werden die Hackmesser vorn leichter und tiefer in den Boden eindringen als hinten, was im Interesse einer guten Hackarbeit vermieden werden muß. Bei anderen Maschinen wird der Scihnittwinkel durch Verstellung jedes einzelnen Parallelogramms ader jedes einzelnen Messers verändert, was aber sehr umständlich und zeitraubend ist. Es sind auch Hackmaschinen bekannt geworden, bei welchen die Parallelogramm-Befestigungsschienen, zwecks Aushebung der Hackmesser, um ihre Längsachse gemeinsam drehbar gelagert sind. Der Hackrahmen dieser Maschinen ist aber in Höhenrichtung nicht parallel verstellbar, sondern schwingt um die Radachse, wodurch bei einer Schnittwinkelverstellung der oben betonte Übelstand des verschiedenen Tiefganges der beiden Messerreihen eintritt. Die vorliegende Erfindung betrifft eine Vorrichtung, mit welcher an einer zweireihigen Hackmaschine mit in Höhenrichtung parallel zum Erdboden verstellbaren Hackrahmen und in bekannter Weise um ihre Längsachse gemeinsam drehbaren Parallelogramm-Befestigungsschienen der Schnittwinkel aller Hackmesser, ohne Beeinträchtigung der Wirkung einer Messerreihe, geändert werden kann. Zur Erläuterung der neuen Vorrichtung dienen die Abb. 1 und 2 der Zeichnung, bei welchen als Beispiel für die Verdrehung der Befestigungsschi'enen eine Schraubenspindel mit Mutter gewählt worden ist. Diese Ver-A good chopping machine is required to have the cutting angle of the chopping knives can be adjusted without losing a lot of time while chopping. They are devices become known, in which this is to be achieved by the fact that the hoe frame rails, to which the parallelograms are attached, are rotated according to the desired cutting angle by ίο the hoe frame is more or less inclined or the rail rotated and in Height direction is adjusted. However, this has the disadvantage of two-row hoeing machines that the front parallelograms come to stand lower than the rear ones. Included the work through the resulting pulling action, the connecting parts of the parallelograms adjust themselves parallel to the ground, the chopping knives are lighter and deeper in the front penetrate the ground than behind, which is avoided in the interests of good hoeing must become. With other machines, the cutting angle is adjusted by adjusting each individual parallelogram vein of each individual knife changed, which is very cumbersome and is time consuming. Chopping machines have also become known in which the parallelogram mounting rails, for the purpose of lifting the chopping knives, are rotatably mounted together about their longitudinal axis. The hoe frame of these machines is but not adjustable in height in parallel, but swings around the wheel axis, whereby In the event of an adjustment of the cutting angle, the above-mentioned inconvenience of the different depths of the two rows of knives occurs. The present invention relates to a device with which on a two-row chopping machine with a chopping frame adjustable in height parallel to the ground and parallelogram mounting rails which can be rotated together in a known manner about their longitudinal axis the cutting angle of all chopping knives can be changed without impairing the effect of a row of knives. To explain the new device, Figs. 1 and 2 of the drawing serve which as an example of the rotation of the fastening rails is a screw spindle has been elected with mother. This ver

Der Hackrahmen besteht aus den beiden Befestigungsschienen α für die Parallelogramme c und den Traversen b. Die Schienen α sind vermittels der Lagerringe d in den Traversen b drehbar gelagert. Mit einer Handkurbel e, welche auch während' des Ganges der Maschine schnell und leicht zu bedienen ist,· können durch Drehen der Schraubenspindel f die Muttern g, welche mit den Führungsstücken h gelenkig verbunden sind, vorwärts oder rückwärts verschoben werden. Dadurch findet eine Drehung der Führungsstücke h und der mit diesen ver- 6g bundenen Rahmenschienen α ohne Veränderung der Höhenlage statt. Mit den Schienen werden auch die daran befestigten Parallelogramme gedreht und können so in eine für jeden gewünschten Schnittwinkel passende Stellung gebracht werden. Der Fortschritt, den diese Erfindung gegenüber den bisherigen Einrichtungen vermittelt, besteht darin, daß nicht nur die Verstellung des Schnittwinkels aller Hackmesser wie bisher gemeinsam durch die auch während des Ganges der Maschine mittels Handkurbel zu bedienende Schraubenspindel oder einer anderen Vorrichtung erfolgt, sondern insbesondere auch die Stellung des Hackrahmens unverändert parallel zum Erdboden bleibt, so daß alle Parallelogramme stets die gleiche Höhenstellung behalten und alle Hackmesser gleichmäßig tief in den Boden eindringen.The hoe frame consists of the two mounting rails α for the parallelograms c and the crossbars b. The rails α are rotatably mounted in the cross members b by means of the bearing rings d. With a hand crank e, which is also quick and easy to operate while the machine is in motion, the nuts g, which are hinged to the guide pieces h , can be moved forwards or backwards by turning the screw spindle f. As a result, the guide pieces h and the frame rails α connected to them rotate without changing the height. The parallelograms attached to them are also rotated with the rails and can thus be brought into a position suitable for any desired cutting angle. The progress that this invention conveys over the previous devices is that not only the adjustment of the cutting angle of all chopping knives is carried out jointly as before by the screw spindle or some other device that can be operated by means of a hand crank while the machine is running, but in particular also the The position of the chopping frame remains unchanged parallel to the ground, so that all parallelograms always maintain the same height position and all chopping knives penetrate evenly deep into the ground.
