Description

Bei den bisher bekannt gewordenen, aus einem Stück hergestellten Fingerbalken für Mähmaschinen sind an den Enden keinerlei besondere Vorrichtungen vorgesehen, um den äußeren und inneren Schuh in sicherer Weise zu befestigen. Überdies werden bei den bekannten Vorrichtungen die mit den hin und her beweglichen Messern zusammenarbeitenden Gegenmesser an den Enden des Fingerbalkens mit den zugehörigen Schuhen verbunden. Die Art der Verbindung der Schuhe und der Gegenmesserplatten mit dem Fingerbalken hat zur Folge, daß die Schuhe wähtrend der Benutzung der Mähmaschine sich häufig lockern, wodurch naturgemäß auch die mit den Schuhen verbundenen Gegenmesserplatten ihre Lage ändern, so daß die erforderliche scherenartige Wirkung von Messern und Gegenmessern nicht mehr erzielt, d.h. die Leistung der Mähmaschine beträchtlich herabgemindert wird.In the one-piece finger bars for Mowers are not provided with any special devices at the ends to secure outer and inner shoe. In addition, the well-known Devices the counter-knives working together with the knives that can be moved back and forth at the ends of the finger bar connected to the associated shoes. The way in which the shoes and the counter knife plates are connected to the finger bar As a result, the shoes turn off while the mower is in use often loosen, which of course also change the position of the counter knife plates connected to the shoes, so that the required Scissor-like effect of knives and counter knives is no longer achieved, i.e. the performance of the mower is considerable is degraded.

Der Zweck der Erfindung ist nun, diesen Nachteil zu beseitigen, und zwar wird dies in erster Linie dadurch erreicht, daß an beiden Enden der Schiene des. Fingerbalkens in Richtung der Finger vorspringende, mit ihrer Oberfläche bündig mit der Unterfläche der Gegenmesserplatten liegende Ansätze zur Befestigung zusätzlicher Gegenmesserplatten und des äußeren bzw. inneren Schuhes vorgesehen sind und der innere Schuh zwei Aussparungen hat, in die die Ansätze bündig eingelassen werden können.The purpose of the invention is now to obviate this disadvantage, as is shown in primarily achieved by the fact that at both ends of the rail of the finger bar in the direction the finger protruding, with their surface lying flush with the lower surface of the counter knife plates for attachment Additional counter knife plates and the outer or inner shoe are provided and the inner shoe has two recesses has, in which the approaches can be embedded flush.

Der Fingerbalken gemäß der Erfindung wird dabei zweckmäßig noch so ausgebildet, daß der Raum zum Einlassen des Balkens im inneren Schuh hinten so breit gehalten wird, daß verschieden breite Fingerbalken verwendet werden können, ohne in irgendeiner Weise die gute Befestigung des Schuhes an dem Balken zu beeinträchtigen. Schließlich sind in dem Balken noch zusätzliche Bolzenlöcher vorgesehen, um die Messerschiene mit dem Balken verbinden zu können, wenn die Schuhe von dem Balken abgenommen worden sind, wodurch der Fingerbalken sich für den' Versand leicht verpacken läßt.The finger bar according to the invention is expediently designed in such a way that that the space for admitting the bar in the inner shoe is kept so wide at the back, that finger bars of different widths can be used without in any way to impair the good attachment of the shoe to the beam. After all, in The beam still has additional bolt holes provided to connect the knife rail to the beam to be able to connect when the shoes have been removed from the bar, whereby the finger bar is ready for shipping easy to pack.

Der Fingerbalken 1 ist in bekannter Weise aus einem Stück mit den Fingern 2 hergestellt, die durch Stege 6 voneinander getrennt und zwecks Bildens einer Aussparung 3 zur Aufnahme der Messer oder Klingen 9' mit einer Zunge 4 ausgerüstet sind. Die Messer 9' sitzen an einer Messerschiene 9, die mit Hilfe der durch Schrauben 11 befestigten Bügel 10 gehalten wird. Die Messerschiene 9 ist verschiebbar in einer über die ganze Länge des Fingerbalkens 1 sich erstreckenden und gleichzeitig zur Verstärkung dienenden Nut 7 angeordnet. In der Nut 7 sind von Zeit zu Zeit Löcher 8 vorgesehen, durch welche etwaige zwischen der Messerschiene und dem Balken sich ansammelnde Teilchen hindurchfallen können. Unterhalb der Zungen 4 liegen zweckmäßig die mit den Klingen 9' scherenartig zusammenarbeitenden Gegenmesserplatten 5.The finger bar 1 is in a known manner made of one piece with the fingers 2, which are separated from one another by webs 6 and for the purpose of forming a recess 3 for receiving the knives or blades 9 'with a tongue 4 are equipped. The knife 9 'sit on a knife rail 9, which with the help the bracket 10 fastened by screws 11 is held. The knife rail 9 is displaceable in one over the entire length of the finger bar 1 extending and at the same time for reinforcement serving groove 7 arranged. In the groove 7 holes 8 are provided from time to time through which any particles that collect between the knife rail and the beam fall through can. Below the tongues 4 are expediently those with the blades 9 'like scissors cooperating counter knife plates 5.

Erfindungsgemäß weist der Fingerbalken 1 an seinem äußeren Ende einen ebenfalls aus einem Stück mit ihm bestehenden Ansatz 12 auf, der einerseits zur Befestigung des äußeren Schuhes 14, andererseits aber auch zur Befestigung der mit der letzten Klinge 9' zusammenarbeitenden Gegenmesserplatte 13 dient. Die Oberfläche des Ansatzes. 12 liegtAccording to the invention, the finger bar 1 also has one at its outer end a piece with it existing approach 12, on the one hand to attach the outer Shoe 14, but on the other hand also for fastening the with the last blade 9 ' cooperating counter knife plate 13 is used. The surface of the approach. 12 lies

Claims

in the same plane as that used to accommodate the counter knife plates 5. Surfaces, the finger 2. The shoe 14 is, as Fig. 3 shows, by a screw 15 and a rivet 16 is connected to the beam 1, and for the passage of these fasteners 12 holes 17 and 18 are provided in the rail 1 and in the extension 12, respectively. the Beam rail 1 engages with lug 12 in the usual recess 19 'of the outer shoe 14 into it.

Except for the double connection of the shoe with the beam rail 1 through the parts 15 and 16 achieved better fastening of the shoe 14 is through the construction described above still achieved that, even if the shoe 14 should loosen, the counter knife plate 13 remains firmly connected to the extension 12 and therefore the correct one Maintains position with respect to the cooperating blade 9 '.

Next, two lugs 20, 21 are provided at the inner end of the finger bar ι which if desired, can be replaced by a single approach of the appropriate width, the surface of the lugs 20, 21 is also in the same plane as that of the counter knife plates 5 bearing surfaces of the fingers 2. A counter-knife plate 22 is attached to the surface of the lugs 20, 21 by rivets 23, which is connected to the first blade 9 ' the knife bar 9 cooperates like scissors.

The in the usual way with Scharniexansätze 25 for receiving the hinge pin The inner shoe 24, which is equipped for tilting the entire finger bar, has recesses 26 (Fig. 6), which correspond in their dimensions to the projections 20, 21 of the rail 1, and in which the lugs 20, 21 when connecting the shoe 24 with the Insert finger bars. The actual connection of the two parts is done by the bolts 27, 28, 29 and 30. As the lip that is otherwise common on the shoe 24 to hold on to the beam rail is omitted, there is enough free space between the hinge attachments and a smooth surface, so that here, as in Fig. 4 and S, by dotted boundary lines show that beam rails 1 of different widths can be accommodated. Of the The same inner shoe 24 can therefore be of different types, in particular of different types, for finger bars Width, find use, as it is with different lengths of the whole finger bar is common.

The connecting bolts 27, 28, 29 and 30! serve, as Fig. 4 shows, at the same time for the attachment of knife holders j 31 and 32, through which the knife rail 9 with the blades 9 provided thereon 'also:' is held and guided in the vicinity of the inner end of the beam ι. However, since the inner shoe 24 and the rail 1 are not connected by the screw bolts 27, 28, 29 and 30 during shipping, the knife holders 31 and 32 could also not be attached. However, in order to be able to pack the finger bar for shipment easier to be in the rail 1, and in the presence [sets 20 and 21 holes for receiving ^f auxiliary bolt 23> 34> 35 ^{un (i} 36 provided, as shown in Fig. 7 shows, 31 and 32 also connect the knife holder already with the rail 1 to when the shoe 24 is not yet attached to the beam 1 ^can.! this auxiliary bolt the knife bar 9 can be attached to the finger bar 1 during shipment.
