ABSTRACT:
The harvesting device for harvesting corn or other grains is embodied as an attachment for a combine and provided with a draw-in device (3) and one picking gap for separating the cobs from the plants (stalks). Furthermore, the harvesting device has one driven picking roller (4) with beater plates per row, as well as a cheek-like guide plate associated with this picking roller (4) and partially enshrouding it, or alternatively, a bracing support extending paraxially to the picking roller and embodied as a driven counter-roller (5). A connection piece (20) acting as a separating and comminuting cutter and stabilizing the distance between the picking roller (4) and the bracing support (5) is disposed in the plant intake (PE) between the picking roller (4) and bracing support (5). This connection piece (20) extends crosswise, preferably at right angles to the plant intake (A) and thus to the longitudinal axis of the picking roller (4) and is formed by a sheet metal plate with an upper cutter edge (21) extending at least almost vertically in respect to the longitudinal axis of the picking roller.
