Description

Self-propelled combine harvester

The invention relates to a self-propelled combine harvester operating according to the axial threshing system with front drive and rear steering axle, as well as with a front cutting unit trough, an inclined conveyor and a wind screen device, with the axial threshing and separating unit as an independent construction / unit in front of the drive axle between the inclined conveyor and the cutting unit trough and is detachable is connected to these two units, which are also designed as separate structural units and wherein the axial threshing and separating mechanism consists of at least two threshing machines mounted in a common housing and separating drums, which are separated by each one of each threshing and separating drum associated passage opening in the rear wall of the The cutting unit trough can be loaded with goods, according to patent ... (P 31 25 659.7).

In a combine harvester according to the main patent, the threshed straw is made up of two in the two end areas surrounding the threshing and separating drums Housing thrown into the field. This is particularly useful with very wide cutting troughs to a swath that makes pick-up presses difficult to pick up. The present The invention is based on the object of avoiding this disadvantage. That will be with a combine harvester of the type described in detail at the beginning

is sufficient that the threshing and separating drums are mounted at an axial distance from one another and from one another have opposite conveying directions and that the housing has only a single central one, the Delivery ends of both threshing and separating drums having associated outlet opening. An alternative solution to this is to be seen in the fact that the Threshing and separating drums in the same conveying directions have, the housing having a central and one provided in an end region of the housing Has outlet opening. According to a further feature of the invention, it has proven to be useful that chopper are assigned to the outlet openings.

In the following, the invention will be based on an exemplary embodiment and several of this schematically depicting figures are explained in more detail. It shows:

In FIGS. 1-3, 1 denotes the front part of a combine harvester, whose axial threshing mechanism 2, which is known per se, is firmly locked to the inclined conveyor 3 via quick-release couplings 4. The axial threshing mechanism 2 carries the cutting mechanism trough 5, also via quick-release couplings 6. For the purpose of road transport, both the cutting mechanism trough as well as the axial threshing mechanism can consequently be easily dismantled. Accordingly, their construction is not subject to any restrictions with regard to their width. Rather, they can only be built with a high throughput in mind. For this purpose, the cutting unit trough 5 has a central dividing finger 7 which divides the cut stalk strips into two partial streams of material. These partial material flows are each fed to one of two through openings 8 and 9 provided in the rear wall of the cutting unit trough 5. In order to achieve this perfectly, the feed roller 10 is equipped with two groups of controlled feed fingers 11 and 12 provided in the area of the through openings 8 and 9, to which the crop to be threshed is fed by two oppositely conveying pairs of screw plates 14 and 15 placed on the roller 10. As can be seen in particular from FIG. 2, insertion drums 16 and 17 with their arms 19 fitted with elastic conveyor strips 18 extend through the through openings 8 and 9 and insert the material to be threshed into the axial threshing mechanism 2. This axial threshing mechanism 2 has two threshing and separating drums arranged in a housing 20 at a distance from one another and with the conveying direction working in opposite directions

21 and 22 on which the threshed straw or Throw the like into the field through a single outlet opening 23 provided in the center of the housing 20, after it has been shredded by the chopper 24 associated with the outlet opening (see Figμr 3.) Below the threshing and separating drums 21 and 22 are each a throw conveyor 25 and 26 on both sides of the chopper 24 arranged, the separated from the threshing and separating drums 21 and 22 grain via intermediate conveyors 27, which correspond to the width of the throwing conveyor, the two at a distance parallel to each other Feed in the scraper chains 29 and 30 arranged in the inclined conveyor channel 3.

The front part of a combine harvester shown in FIG. 4 differs from that in this respect shown in Figure 1, as that the housing 20 'has two outlet openings 23' and 23 ", where the threshed straw or the like from two threshing and separating drums 21 'and 22 'is supplied, the conveying direction of the separating drums 21' and 22 'being the same. Of course it is necessary to open the through openings 8 'and 9' of the cutting unit recess 5 ' to lay so that they are in front of the task area of the threshing and separating drums 21 'and 22 'are located. The feed roller 10 'is occupied with corresponding worm plates, which The crop in front of the through openings 8 'and 9' the groups of feed fingers.
