Abstract
In a machine for working soil, the oscillating arms 6, 7 of the opposite toothed bars 2, 3, 4, 5 on different rows 27, 28 are mounted at least approximately side-by-side in a direction crosswise to the direction of advance 24.
Claims24
A machine for working soil, said machine comprising:
- (a) a chassis having a direction of advance during use of said machine;
- (b) a device mounted on said chassis for hitching said machine to a tractor source;
- (c) a first row comprising two bars at least approximately aligned in a direction crosswise to said direction of advance and equipped with tools for working the soil;
- (d) a second row comprising two bars at least approximately aligned in a direction crosswise to said direction of advance and equipped with tools for working the soil, said second row being placed behind said first row in said direction of advance;
- (e) a bearing mounted on said chassis;
- (f) a shaft having an axis of rotation which is at least approximately parallel to said direction of advance journaled in said bearing, said shaft being adapted to be rotated around its axis of rotation by a power source;
- (g) a plurality of eccentrics mounted on said shaft, said plurality of eccentrics being distributed around said axis of rotation of said shaft;
- (h) a plurality of connecting rods each one of which has a first end and a second end, the first end of each one of said plurality of connecting rods being connected to a corresponding one of said plurality of eccentrics, and the second end of each one of said plurality of connecting rods being pivotally connected to a corresponding one of said bars;
- (i) a plurality of first rigid oscillating arms, wherein;
- (i) each one of said plurality of first oscillating arms has a first upper articulation means and a first lower articulation means
- (ii) each one of said first upper articulation means is pivotally connected to a corresponding one of a plurality of first upper articulation members mounted on said chassis so as to form a first upper articulation
- (iii) each one of said first lower articulation means is pivotally connected to a corresponding one of a plurality of first lower articulation members mounted on a corresponding one of said bars of said first row, so as to form a first lower articulation and
- (iv) each one of said first upper and lower articulations has an axis at least approximately parallel to said direction of advance
- (j) a plurality of second rigid oscillating arms wherein:
- (i) each one of said plurality of second oscillating arms has a second upper articulation means and a second lower articulation means
- (ii) each one of said second upper articulation means is pivotally connected to a corresponding one of a plurality of second upper articulation members mounted on said chassis, so as to form a second upper articulation
- (iii) each one of said second lower articulation means is pivotally connected to a corresponding one of a plurality of second lower articulation members mounted on a corresponding one of said bars of said second row, so as to form a second lower articulation and
- (iv) each one of said second upper and lower articulations has an axis at least approximately parallel to said direction of advance;
- and
- (k) said first and second oscillating arms being arranged in a plurality of pairs of oscillating arms each one of which comprises a first oscillating arms and a second oscillating arm and wherein:
- (i) said pairs of oscillating arms are spaced from each other crosswise to said direction of advance
- (ii) in each one of said pairs of oscillating arms, said first and second upper articulations extend side-by-side crosswise to said direction of advance and
- (iii) in each one of said pairs of oscillating arms, said second lower articulation is offset backwardly in respect to said first lower articulation when considering said direction of advance.
