BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled combine having a traveling mechanism and a threshing device that is installed laterally to the traveling direction and that operates based on an axial flow system. And a transporting device for transporting a mixture of grain and rice husk to a transporting surface of a filter device below the threshing device.

[0002]

2. Description of the Related Art A threshing device, which is mounted transversely to the direction of travel and which operates on the basis of an axial flow system, is described in detail in German patent application DE 37 38 991 A1 on the basis of known technology. A self-propelled combine equipped with a combine is known. Such a combine is
After the straw has passed through the threshing device, it is lowered laterally next to the combine. Such a machine as described above, however, has a caterpillar drive mechanism which is expensive to manufacture and to operate. Furthermore, Federal Republic of Germany Patent Publication No. 1222
No. 307 is likewise known as a self-propelled combine having a threshing device which is mounted transversely to the direction of travel and which operates on the basis of an axial flow system, and which is also equipped with a wheel drive mechanism. .

The arrangement of the traveling mechanism and units of the combine described above is small, compact and correspondingly inexpensive, and at the same time has a threshing device and a wheel traveling mechanism which are mounted sideways to the traveling direction. It is impossible to manufacture a self-propelled combine harvester. In a small and compact self-propelled combine as described in DE-A-3738991, the German Federal Patent Publication No. 122
It is not easy to attach the wheel traveling mechanism to the known position shown in the specification of 2307. This is because otherwise, the length of the threshing device must be shortened so that the vehicle width does not become too wide, and the straw lowering is further hindered. On the other hand, although the self-propelled combine shown in DE 122 22 307 has a wheel drive mechanism, the individual actuating mechanisms are very disadvantageously arranged and therefore With such an arrangement, it is not possible to manufacture a combine that is small, compact and reasonably cheap.

[0004]

SUMMARY OF THE INVENTION The object of the invention is to improve a combine of the type mentioned at the outset by providing a combine of the type which is small and compact on the one hand and on the other hand can be equipped with a wheel drive mechanism. Is.

[0005]

In the construction of the present invention for solving this problem, the front axle of the combine has a substantially right angle in front of the threshing device as viewed in the traveling direction and at the front of the main frame of the combine. 3 near the end of the inclined conveyor and between the feed opening and its delivery end.
It is located below the one-half part. In another aspect of the invention, the rotor at least partially overlaps the front wheel at its straw discharge end, and the casing surrounding the rotor and the transport device located below it faces the interior of the casing. It has a notch. A front wheel at least partially overlapped by the rotor is movable along the outer limiting surface of the notch. In order to make full effective use of the component space below the threshing device, a transmission for switching the drive force transmission to the front axle is arranged below the threshing device. For mounting the braking device, it is proposed to arrange at least one brake disc on the output shaft of the transmission. Furthermore, the longitudinal spacing between the transmission and the front wheel axles is intermeshed via and belonging to at least one output shaft for the transmission of the driving force from the transmission to the front wheels. At least 2
Bridged through two gears. In this case, one of the gear wheels is connected to the axle of the front wheel in a non-rotatable manner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows front wheels 4, 6 and rear wheels 8,
A self-propelled combine 2 is shown with a wheel drive mechanism consisting of 10 and a thresher 12 which is mounted sideways and operates on the basis of an axial flow system. Below the threshing device 12, there is arranged a carrying device 14 for carrying the mixture of grains and rice husks to the carrying surface of the filter device. The threshing device 12 and the transport device 14 are surrounded by a casing 16. At the time of harvesting, the cropping device 18 cuts the harvested product, and the laterally inclined conveyor 20
And further from the inclined conveyor 20 to the threshing device 12. A mixture of threshed kernels and rice husks falls through a filter opening onto a transport device 14 located below and is sent from the transport device 14 to a cleaning filter 22, whereas threshed straw is Passes through the discharge opening 24 of the threshing device 12, drops from the discharge opening 24 onto the belt conveyor 26, and from the rear end of the belt conveyor 26 into a line on the field.

In FIG. 2, the axles 28 of the front wheels 4 and 6 are three-dimensionally arranged below the inclined conveyor 20 and in front of a substantially right-most front pillar (not shown in detail) of the main frame of the combine 2. Has been done. The driving force is transmitted from the motor 30 to the transmission 32 in a known manner, and is guided from the transmission 32 through the output shaft 34 into the drive casing 36. A brake device 38 is arranged on the output shaft 34. Axle 28
Gears 40 are arranged in the drive casing 36 in order to position the wheels as far forward as possible. This gear 40
Is adapted to transmit the driving force from the output shaft 34 to the axle 28, and at the same time, bridges the distance between the axle 28 and the body of the self-propelled combine 2 in an inexpensive manner.

On the one hand, in order to be able to achieve the largest possible length of the threshing device 12 and, on the other hand, the narrowest possible vehicle width, the casing 4 has a hatched surface 4.
The region 2 has a notch facing the inside of the casing 16. Along the outer boundary of the notch, the front wheels 4 at least partially overlapped by the rotor
Exercise. The rotor of the threshing device 12 is mounted high enough to allow the front wheels 4 to completely overlap within the vehicle width.
