ABSTRACT:
In a single grain sowing machine, the seed grains (0) supplied out of the seed container (1) are separated by means of a feeding wheel (2). This feeding wheel (2) is covered up to a point where it leaves the housing (8). There is also a sowing wheel (4) which rolls on the ground and on the circumference of which there are means which engage the seed grains (0) that are already separated in the cells (7) of the feeding wheel (2) and transfer them out of the cells into the path of movement and the circumferential speed of the sowing wheel (4). The circumferentially measured spacing of the cells (7) of the feeding wheel (2) is to the circumferential spacing of the seed grains (0) held by the means of the sowing wheel (4) as is the ratio of the circumferential speeds of these two wheels. In the lower zone of the sowing wheel (4), the seed grains (0) are pressed into the soil and released (FIG. 1).
