ABSTRACT:
The invention solves the problem of eliminating the transfer of the combine eight onto a conveyor through a chain instead of through a railing, in the combines which are advanced by means of a link chain meshing with a rack fixed alongside of the conveyor.
To this end the slide skid (7) forcing the chain (1) to mesh with the rack (8) is provided with a tubular slipper (10). The tubular slipper (10) encloses a railing (11) situated in the gates of the conveyor (9) close to the rack (8). The tubular slipper (10) is mounted on a cranked axle (12). The cranked axle (12) has - on the end of the pin embedded in the slide skid (7) - a splined tip (16) embedded in a grooved hole (17) which has a common geometrical axis (15) with the pin of the cranked axle (12), the said pin being embedded in the slide skid (7). The tubular slipper (10) mounted on the pin (14) of the cranked axle (12) is protected against slipping off into the tubular slipper (10).
