Abstract:
1. A machine for bedding out seed or plant tapes comprising: a frame; a carrying pole to be connected to a front of a tractor frame; at least one bedding out unit provided with a plough member mounted on said frame, wherein the plough member is associated with a conveyor including at least one continuous belt, and wherein the bedding out unit is provided with a supporting plate for supporting at least one supply container for the seed or plant tape to be bedded out in a furrow produced by the plough member, the bedding out unit including a plough member of a substantially U-shaped cross section, where top webs of the U are substantially horizontally projecting stabilizing webs, and where said plough member is of a length (L) of at least approximately 30 cm and a width (b) measured across the U of 15 to 50 mm, the conveyor of said plough member being formed by an inclined main conveyor with two continuous conveyor belts arranged adjacent, but with a distance (a) to one another, said main conveyor extending over most of the entire length (L) of the plough member, the supporting plate being adjustable with respect to at least one of a height and angle, and at least two pressure wheels being mounted on a rear end of the machine for pressing down the earth around the seed or plant tape portion which has just been bedded out in the furrow; a pre-conveyor provided between the supporting plate for the supply container and the main conveyor, said pre-conveyor being adapted to run at a speed slightly slower than a speed of the main conveyor, and wherein said pre-conveyor is mounted on a slide reciprocable in the longitudinal direction of the machine; and a pair of co-acting separation rollers mounted between the main conveyor and the pre-conveyor, a peripheral speed of the separation rollers corresponding substantially to an advancing speed of the main conveyor.
