Abstract

The present invention relates to a self-propelled combine harvester, the combine comprising a wheeled traveling device and a threshing and sorting device arranged transverse to the travel direction and operated according to an axial-flow system.

Description

Self-propelled combines with threshing and sorting devices arranged laterally

The present invention relates to a self-propelled combine having a wheel-type traveling mechanism and a threshing and sorting device which is installed in a transverse direction and operated in an axial flow system manner, and below the threshing and sorting device is a grain / A conveying device is installed to convey the bran mixture to the conveying bottom of the screen device.

Prior art self-propelled combines, such as those described in detail in DE 37 38 991, have a threshing and sorting device which is installed transverse to the direction of travel and operated in accordance with the axial flow system, which combines straw threshing and After passing through the sorting device, the straw is discharged to the side of the combine. However, such combines are equipped with a trackless traveling mechanism which is expensive in terms of manufacture and operation. In addition, the self-propelled combine disclosed in DAS 1 222 307 is similarly provided with a threshing and sorting device which is installed in the transverse direction of the traveling direction and operated in an axial flow system manner, and a wheel-type traveling mechanism.

In the structure of the traveling device and assembly of the above-mentioned combine, it is small and compact, and accordingly economical, and at the same time to manufacture a self-propelled combine having a wheel-type traveling mechanism and a threshing and sorting device which is provided transverse to the traveling direction. It is impossible. However, in the case of the compact and compact self-propelled combines disclosed in DE 37 38 991, it is not possible to simply mount the wheel drive mechanism in a known position, as disclosed in DAS 1 222 307, because the combines are not too wide. To avoid this, the threshing and sorting device must be shortened, which prevents the straw from being discharged. On the other hand, the self-propelled combine disclosed in DAS 1 222 307 also has a wheel drive mechanism, but since individual actuating members are undesirably mounted, it is not possible to produce a compact and compact accordingly.

It is an object of the present invention to provide a combine which can be equipped with a compact and compact wheeled driving mechanism of the type described in detail in the introduction.

The object of the present invention is to feed the front axle shaft of the combine in front of the threshing and sorting device, in front of the approximately vertical strut of the foremost of the main frame of the combine, and the feed opening of the inclined conveying channel and its view in the direction of travel. This is achieved by placing below the portion corresponding to about one third of the discharge end in terms of the distance between the discharge ends. According to another feature of the invention, at the straw discharging end, the rotor extends at least partially over the front wheel, and the housing surrounding the rotor and surrounding the conveying device disposed below it has its own clearance projecting inwardly. Is formed and the front wheels at least partially overlapped by the rotor move along the outer boundary of the free space. In order to use the entire space below the threshing and sorting device, a transmission for changing the driving force transmitted to the front axle shaft is disposed below the threshing and sorting device. A proposal for accommodating a braking system is to mount one or more braking discs on the output shaft of the gear mechanism. Further, in order to transmit the driving force from the transmission to the front wheels, the longitudinal distance between the transmission and the axle shaft of the front wheels is connected by one or more output shafts and two or more gear wheels which are attached to and interlocked with the output shafts. One is mounted relative to the axle shaft of the front wheel without rotation.

Hereinafter, the present invention will be described with reference to the embodiments shown in the accompanying drawings.

FIG. 1 shows a self-propelled combine 2 with wheeled drive mechanisms with front wheels 4 and 6 and rear wheels 8 and 10, which are arranged transversely in an axial flow system manner. An activated threshing and sorting device 12 is provided. At the bottom of the threshing and sorting device 12 is a conveying device 14 for conveying the grain / bran mixture to the conveying bottom of the screen device. The threshing and sorting device 12 and the conveying device 14 are surrounded by a housing 16. During harvesting, the harvest is cut by the cutting mechanism 18 and transferred to the transversely inclined conveyor 20, from the conveyor 20 to the threshing and sorting device 12. The threshed straw is threshed through the discharge opening 24 so that the threshed grain / bran mixture is lowered through the screen to the conveying device 14 disposed below it, while passing from the conveying device to the cleaning screen 22. It is discharged from the sorting device 12. The threshed straw falls from the discharge opening 24 to the transfer belt 26 and falls in a row from the rear end of the transfer belt to the ground.

FIG. 2 shows the axle shaft 28 of the front wheels 4, 6 arranged at a distance below the inclined conveyor 20, which is approximately perpendicular to the foremost front of the main frame of the combine. It is disposed in front of the strut 50. The driving force is transmitted from the motor 30 to the transmission 32 according to a known method, which is transmitted from the transmission to the drive housing 36 via the output shaft 34. On the output shaft 34 a braking device 38 is arranged. In order to position the axle shaft 28 as forward as possible, a gear wheel 40 is arranged in the drive housing 36. This gearwheel transmits the driving force from the output shaft 34 to the axle shaft 28 while connecting the distance between the axle shaft 28 and the self-propelled combine 2 body in a cost effective manner.

On the one hand, in order to make the threshing and sorting device 12 as long as possible and on the other hand the width of the device as narrow as possible, the hatched surface area 42 of the housing 16 is provided with a free space projecting toward the inside of the housing. It is. The front wheels 4 at least partially overlapped by the rotor move along the outer boundary of the clearance. The rotor of the threshing and dividing device 12 is installed at a level high enough to protrude above the front wheels 4 to reach the full width of the combine.
