Claims

The invention relates to a device for cutting hay and straw into short pieces (Chaff) from the stack. Previously, the individual sheaves had to be fed to the cutting device which is particularly time-consuming when the material to be cut is stored in a different location. That Part of the property is lost here, should only be mentioned in passing.

These disadvantages are eliminated according to the invention in that a cutter consisting of several juxtaposed reciprocating knives is used at the storage location, namely on the stacked material to be cut, whereby no movement of the material is required before cutting. Another advantage is that you no longer need to cut the material used for fodder purposes and therefore no longer need a storage room for this purpose, so that it can be used for other purposes. In a short time you can only cut as much hay or straw as you need for feeding. This also has a positive effect on the thriving of the animals, which now always receive freshly cut feed. As is well known, food that has been cut in advance soon becomes stuffy and in this state no longer eagerly ingested by the animals.

In the drawing, the invention is shown schematically in one embodiment.
Fig. Ι shows the front view of the cutter; Fig. 2 shows a side view of a knife with a wavy edge;

Fig. 3 shows the conveyor connected to the cutting device, and

For example, Fig. 4 shows the cutter in use from the side.

On a stack of hay or straw α , the cutter b is placed by means of a mobile crane c and remains to secure against any sliding off the stack and to maintain the horizontal position z. B. connected to the crane by means of a pulley. The cutter itself consists of several knives d arranged next to one another at certain intervals, which, guided in slots, perform a reciprocating movement and cut the material to be cut into small pieces in its entire length and width from the top to the bottom of the stack, the size of which depends on the distance between the individual knives. The accumulated cut material is either discharged through a built-in conveyor e or by a suction device according to the open side of the stack, where it falls to the ground or in a attachable to the cutter container (ο bag. The like.) / Is collected. Since the weight of the cut material is low, the container can be designed as a light conveyor vehicle that ο by means of an elevator device. Like. Up and down can be performed. A motor g is provided for the drive, which in a known manner sets both the knives d and d, ie the built-in conveyor device e or a suction device, in motion. The cutting edge of the knife d is wave-shaped so that it has a saw-like effect. The circulating chains, which are arranged between the individual knives d and serve as a conveyor device, are provided with drivers h which are designed as pivotable links and which automatically fold when not in use.

By uncoupling several knives, the system can also be used to cut straw.
