Abstract
The process serves for the loosening of soil in the subsoil and topsoil areas and for introduction of fertilizers as well as subsoil loosening and/or for soil cultivation as well as the introduction of other additives with the use of digging tools 2, 2', and 2" by which the soil is broken up. In this case, the digging edge of digging tool 2, 2', and 2" is guided in an elliptical motion and this motion is superimposed by a straight motion, i.e., the driving motion. A cycloid is therefore produced for the digging edge. The longer axis of the ellipse in this case is directed from the soil surface into the soil in this manner and exhibits an angle to the travel direction. The additive, such as, for example, fertilizers, can be blown into the fissure forming behind tool 2.
Claims20
Soil loosening apparatus to partake of a predetermined travel distance, comprising a crossbeam (1) serving a support for digging tools (2, 2', 2") and linked through a first knuckle joint (P4) aligned perpendicular to the travel direction on a frame connected tightly with a traction vehicle and tiltable in a vertical plane extending in the travel direction by means of crank or eccentric drive (4) around said first knuckle joint (P4) engaging through a second knuckle joint (P5) with crossbeam (1), characterized by the fact that first knuckle joint (P4) is arranged at the lower end of a lever (3) with preselectable lever length (l.sub.5, l.sub.5'), whose upper end is linked on the frame connected tightly with the traction vehicle in a preselectable position through a third knuckle joint (P1 . . . P3) aligned perpendicular to the travel direction, that the distance of the third knuckle joint (P1 . . . P3) from said knuckle joint (P5) is smaller than the sum of lengths (l.sub.5, l.sub.5') of said lever (3) and the distance (l.sub.1) of said first knuckle joint (P4) from said second knuckle joint (P5), that the diameter of the circle described by crank drive does not intersect with the connecting line between said first knuckle joint (P4) and said third knuckle joint (P1 . . . P3), and that the length of lever (3) is larger than the radius of the circle described by the crank drive;
- further characterized by the fact that the eccentric drive (4) and crossbeam (1) are suspended on a transverse support (19) with a side piece (20) projecting generally perpendicularly therefrom, which side piece has various longitudinally spaced holes (21) to which the upper end of lever (3) may be variantly connected with corresponding variance in the longitudinal displacement of knuckle joint (P3), which is the center of motion, compared to knuckle joint (P4) thereby varying the longitudinal distance of the center of motion compared to knuckle joint (P4).
