Abstract
A harrow device for the conditioning and leveling of sowing soils in a single step, and a disc for the harrow, which allows these processes to be carried out in the proper way, guaranteeing a better quality of subsequent sowing, and also preventing premature wear of parts, jamming of materials, and/or emergency stops, and which, in turn, is constituted and built in a simple way, in order to reduce costs and facilitate both its realization and its replacement.
Claims11
A harrow device for the conditioning and leveling of sowing soils, the harrow device comprising:
- a frame which has a front pulling part;
- wheels mounted on said frame;
- and
- a plurality of harrow means arranged below the frame,
- wherein each harrow means of the plurality of harrow means comprises:
- at least a plurality of discs removably connected to each other by means of connecting members comprising at least one base plate removably fixed to each of said discs and joint means fixed to the base plate, such that the joint means of two adjacent discs are articulately connected to each other;
- and
- at least one tensioning means mounted on said frame and connected to said harrow means.
A harrow disc for a harrow device that comprises at least a plurality of said discs removably connected to each other by means of connecting members comprising at least one base plate removably fixed to each of said discs and joint means fixed to the base plate, such that the joint means of two adjacent discs are articulately connected to each other, the harrow disc comprising:
- at least one disc plate provided with a plurality of fixing holes;
- said joint means comprising at least one pair of half-links, where at least one of said half-links is arranged on each side of the disc plate, each of said half-links having one of said at least one base plate that is in operative contact with a face of said plate disc and is provided with holes that coincide in alignment with respective holes of the plurality of fixing holes of the disc plate;
- at least one pair of counterweight plates, where at least one of said counterweight plates is provided on each side of the disc plate, each of said counterweight plates having holes that are aligned with respective holes of the fixing holes of said disc plate;
- and
- fixing elements that pass through the holes made in the counterweight plates, the base plates of the semi-links and the disc plate, operatively fixing them to each other in a removable manner.
