BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a transport and cutting unit for loading wagons with an upwardly directed transport channel in the loading space of the carriage and several at the upper end of the transport channel with mutually spaced, adjacent cutting blades.

Such aggregates are e.g. described in DE utility model specification 19 32 424. In the embodiments proposed here, the cutting blades are positioned in the transport direction after the crank loops that are controlled by crankshafts, that considerable frictional and clogging losses occur during the transport between the moving conveyor teeth and the rotating teeth. driven cutting blades yet remaining transport channel part. Furthermore, large frictional losses occur when transporting the crop along the bottom and cover plates in the transport channel.

Another example of an assembly according to the invention is described in DE utility model specification 19 60 114.

The invention has for its object to provide a transport and cutting unit with a particularly low energy demand, which works gently for the material and enables a simple construction.

According to the invention, it is achieved that the conveying channel for reducing wall friction in the crop stream to be transported upwards is formed on its front and rear side by transporting means and that there is no adjacent fixed housing and transport channel wall behind the cutting blades that stand in contact with a rotary driven conveyor tooth rotor and behind the conveyor tooth rotor in the conveying direction.

The missing house wall could result in a wrong stop of the crop-25 stream by sectioning. Therefore, it can be further suggested that the cutting blades outside the operating range of the transporting tools in the conveying apparatus have a hook-shaped projection which can support the harvested material during the cutting.

The transporting means arranged to reduce the wall friction consist of several drums arranged one behind the other. These drums can carry or be lightly profiled, but also smooth.

In a particularly simple embodiment, it is suggested that the drums are driven in one row (e.g. the rear) while in the other row they are not driven but are rotatable.

35 The drawing schematically shows a transport and cutting unit according to the invention, seen from the side.

On the front of a loading cart not shown further, a recorder 1. Located behind it are mounted three driven rear transport drums 2, 2 ', 2 "which rotate in the direction of arrows A in the side walls of the loading cart.

5 Above and in front of them are mounted two similarly driven front conveyor drums 3, 3 'which rotate in the direction of arrows B. The recorder 1 has teeth 4. Above it is a guide plate 5.

Above and behind the rear conveyor drum 2 "and the front conveyor drum 3 'is rotatably mounted a rotary conveyor 6 in the direction of arrow C, on whose core 7 is attached a plurality of disc-shaped conveyor stars 8, each carrying four rearwardly bent teeth 9. The wipers 10, which are attached to a transverse carrier 11, engage the space between two adjacent transport stars 8.

On one frame carrier 12, fixed or pivot in gt are mounted several ice cutting knives 13. They also engage in the area of the transport apparatus 6 between two adjacent transport stars 8. The cutting blades 13 have a cutter 14 and a hook-shaped projection 15 which extends up to near it. rear transport roller 2 ”circumference.

In the operation of the loader, a material strand is taken up from the ground 20 by the teeth 4 and passed between the recorder 1 and the guide plate 5 to the rear transport drum 2. It takes over the material stream which is then transported upwards in a transport channel 16 formed by the rear transport drums. 2 ', 2' and the front conveyor drums 3, 3 '.

At the end of this transport channel 16, the material string of the teeth 9 is gripped onto the transport stars 8 and pressed in a direction towards the stationary cutting blades 13 and cut into pieces. The broken tea straw then enters the connecting cargo space 17. The pieces of material found between the transport stars 8 are removed from the wipers 10.

The transport channel 16 may also be formed by other than the transport elements shown here. It is only important that the material string is transported upwards in uncut mode and that it is first cut at the upper end of the transport channel 16.
