PATENT OFFICE,

As is well known, the potato harvesting machines are made in their effect by the machine frequently constipating chewy potato haulm hampered. You already have devices suggested which the herb should cut up before the actual harvesting machine. So is in the Swiss patent specification 21087 the arrangement of a circular saw-like knife disc in a slotted one Bracket described. The hanger is here to lift the herb so that it can be removed from the knife disc is cut up; but the cutting length of the knife disc is so small that the Herb, if it is in a dense tangle, can be found partly over the knife disc can push up and then uncut the machine · clogs. It also appears possible that the herb lies against the bracket from below without being lifted; in this case it can, with its great toughness, differ from the slowly rotating one Knives are not cut at all. In the device of the German patent 88190 a horizontally working knife wheel is used, which the herb through a downwardly resilient fork is fed. Here, too, it is possible that the Herb can dodge by sliding it over the knife.

The present invention now relates to a potato cabbage cutter in which prevents the herb from escaping not only downwards, as before, but upwards is. For this purpose, the known knife wheel is arranged in a slot of a bracket in a manner similar to that in FIG of the cited Swiss patent specification and illustrated. At the bottom A downwardly movable shoe, which is also known per se, is attached at the end and lifts the herb lying on the ground in a known manner. To evade To prevent the herb over the knife wheel is a downwardly curved one at the upper end of the knife slot Bracket attached, over which the herb cannot pass. So the herb is at of the present device retained by the upper fixed bracket so that here an upward evasion of the herb is made impossible. Since only the as Haulm lifter, the lower part of the device, is designed to cope with the unevenness of the ground can adapt, so it is possible that the knives strike into the earth. This The problem is eliminated by attaching a hinge over the knife slot.

The drawing shows the new cabbage cutter, namely:

Fig. Ι a side view, Fig. 2 is a front view and

Fig. 3 shows a modified embodiment.

In an iron knee I is in a slot 2, a knife wheel of any ' Arranged type. It is advisable that the cut surface of the knife is not too small. choose to process the heavily accumulating herb quickly. The knee must be be strong enough to allow space for the knife wheel and not to bend. The shaft of the knife wheel is purposeful

moderate in the knee of the piece

I arranged

and carries a gear 4, which is covered from the front by a protective plate 5 (Fig. 2), so the herb does not get into the teeth of the wheel 4. The lower end of the knee 1 is designed as a haulm lifter and for this purpose it is pointed at the front, but downwards rounded it off. cannot burrow into the ground. Around. to prevent yourself the lower end of this lifter works into uneven ground, and on the other hand, to ensure that the potato leaves lying directly on the ground the knife wheel is fed, a joint 6 is arranged so that the as Haulm lifter serving part adapt to the ground elevations in a known manner, but cannot go down beyond a certain position. The knife slot in the elbow expediently extends to approximately that Joint so that the herb lifted by the haulm lifter is immediately exposed to the action of the Knife wheel is exposed. In order to prevent the herb from being too abundant over the knife wheel "after at the top, there is a at the top of the knife slots. Bracket 10 arranged, which is bent downwards and, due to its position and shape, allows the potato herb to descend further under all circumstances prevented. The cabbage cutter designed in this way can be opened by means of a known clamping bracket Attach 7 to each potato harvester in the desired position. Simultaneously a sprocket 8 must be attached to the front axle of the machine, which is his Movement by means of the chain on the wheel respectively. the shaft of the knife wheel 3 transmits.

With this design it can happen that the knives hit the ground when the Haulm lifter is raised by a raised ground. To prevent this from happening, will after 'the embodiment of Fig. 3 that Joint 6 arranged over the knife wheel 3 so that the haulm lifter is still the knife wheel and includes the bracket. The knife wheel then makes the movement of the herb, hebers with. The chain is over two rollers 9 on the immovable part of the knee guided so that the rotary movement of the lower part with the knives is possible.

As a result of the arrangement of the two haulm supply means, the haulm lifter and of the bracket 10 at both ends of the knife slot is an evasion of the potatoes safely prevented up or down.
