COMBINED IMPLEMENT FOR CRUSHING, GRUBBING, DECOMPACTION AND WORKING OF THE SOIL

摘要

Said implement comprises agricultural tools rotating with respect to teeth fixed to a frame. Said rotating agricultural tools, of large and small diameters, are combined into a rotor so that the large diameter tools are arranged between the teeth (5) and that the small diameter tools are arranged in planes defined by said teeth. The profile of the front part (5a) of the teeth (5) is comprised, at the top portion, of an arc of a circle (C1) of which the center is situated on the axis X1 of the rotor and of which the radius (R1) is slightly bigger than the minimum working radius (R2) of the small diameter rotating tools and, at the bottom portion, of an arc of a circle (C), having the same radius (R1) as that of the top portion, but of which the center is situated on an axis (X2) parallel to the axis (X1) of the rotor offset in the vertical plane by a distance (D) in order to obtain a progressive contraction of the distance separating the front part (5a) of the teeth (5) from the crushing blades (24) of the small diameter rotating agricultural tool (8). The rotating agricultural tools are comprised of a side plate (20 or 23) at the periphery of which are mounted crushing (24), mixer (22) or scraper blades. The working part of said blades is twisted to form a helix and laterally inclined alternatingly to the right and to the left of the side plates.
