Agricultural tool-holder
View Patent ↗Agricultural tool-holder having a central chassis with a coupling system for coupling with a tractor and at least one lateral chassis that can slide closer to or away from the central chassis, which has a longitudinal axis and includes an adjacent parallel pair of tubular beams orthogonal to the longitudinal axis and suitable for slidingly receiving two rods provided in the lateral chassis, moved by a main actuator mounted in the central chassis.
1. An agricultural tool holder comprising:
a central chassis adapted to support a three-point coupling system for coupling with an agricultural tractor, said central chassis housing hydraulic and electrical parts that actuate articulated components of the tool holder;
at least one lateral chassis mounted so as to be slideable toward or away from said central chassis, wherein said central chassis has an axis of symmetry and comprises a parallel pair of tubular beams disposed orthogonal to the axis of symmetry of said central chassis, wherein said at least one lateral chassis has a parallel pair of rods respectively inserted and slidable within the parallel of tubular beams so as to telescopically support said at least one lateral chassis; and
at least one actuator cooperative with said at least one lateral chassis so as to move said at least one lateral chassis, said at least one actuator being mounted on said central chassis, wherein the parallel pair of rods are rigidly connected by a pair of spacing bars, one sparing bar of the pair of spacing bars being interposed between the parallel pair of rods and screwed to the parallel pair of rods, another spacing bar of the pair of spacing bars being interposed between the parallel pair of rods and screwed of the parallel pair of rods at a center of the parallel pair of rods, the parallel pair of rods being inserted into the respective parallel pair of tubular beam by a section equal to approximately one-half of a length of the parallel pair of rods.
2. The agricultural tool holder of claim 1 , wherein the pair of spacing bars support a bridge element, the bridge element supporting a tool-holding plate and a depth wheel.
3. The agricultural tool holder of claim 2 , wherein the bridge element has a pair of shaped flanges having holes therein, the holes allowing the pair of spacing bars to be inserted therein.
4. The agricultural tool holder of claim 3 , wherein a pair of collars are interposed and welded between the pair of shaped flanges, wherein the depth wheel is supported by a leg, the leg being inserted inside the pair of collars.
5. The agricultural tool holder of claim 4 , wherein said at least one actuator is a hydraulic jack having a stem, one of the pair of shaped flanges having a perforated shank to which the stem is coupled.
6. The agricultural tool holder of claim 3 , wherein the bridge element supports the tool-holding plate, the tool-holding plate having a flange with a pair of brackets, each of the pair of brackets having a sickle shape and having a hole at an proximal end thereof into which the spacing bar is inserted.
7. The agricultural tool holder of claim 6 , wherein each of the pair of brackets has a hole at a distal end thereof into which a pin is inserted, the pin having a sleeve.
8. The agricultural tool holder of claim 1 , said at least one lateral chassis is a pair of identical lateral chasses support respectively on opposite sides of said central chassis, each lateral chassis of the pair of identical lateral cases being slidable toward or away from said central chassis along an orthogonal direction relative to the axis of symmetry of said central chassis.
