Abstract
An assembly for weed cutting in the inter-furrow of both extensive and intensive crops, including a main body that operates in a horizontal plane with three mounted propellers. One propeller remains fixed at its central location, while the other two have radial movement that can be manually or computer-controlled and can be positioned in front of or behind the fixed propeller. All three propellers are driven by a motor, independent of the forward movement of the machine or agricultural implement to which it is attached via the front tool bar through components forming a parallelogram. This setup facilitates weed cutting in the inter-furrow of crops and ensures soil surface protection by incorporating two linearly arranged leveling wheels.
Claims15
A three-propeller inter-furrow weeder assembly comprising:
- a main body (4) that operates in a horizontal plane;
- three propellers (10, 15, and 16) are mounted and obtain rotation in one direction from a motor (9), independent of a forward movement of an agricultural machine or implement to which the three-propeller inter-furrow weeder is attached via the front tool bar (3) through components forming a parallelogram body (2), facilitating its operation in the inter-furrow of crops to cut weeds:
- the main body (4) defines a flat rectangular shape with rounded corners, and includes a central through-hole housing a hollow cylindrical body (7) containing a cylindrical shaft (8) with threads at both ends extending beyond the limits of the hollow cylindrical body (7), incorporating at the lower end one of the three propellers (10) fixed spatially and at the opposite end a motor;
- wherein the hollow cylindrical body (7) is linearly connected to a first trapezoidal body (29) which is solidarity linked to a second trapezoidal body (23) to which parallel arms of a parallelogram body (2) are freely attached;
- wherein the perpendicular opposite arms are fixed to a rectangular longitudinal body (3) belonging to the agricultural machine;
- wherein inside the parallelogram body (2) linked to the trapezoidal body (23) is a hollow cylindrical body (34) housing an internal threaded body through which a threaded shaft moves;
- wherein an upper end of the threaded shaft forms a crank handle (25) and at the opposite end is coupled to a fork body (26) with a wheel (27);
- wherein below the line where the hollow cylindrical body (7) and the trapezoidal body (29) are fixed, a vertical quadrangular body with a central through-hole serves as a pivot for a rectangular body (32) with a fork-shaped end (33) housing a wheel (28);
- wherein near the pivot point and on the rectangular body (32) is a horizontally developed rectangular body with a central threaded hole through which a threaded shaft (31) moves, connecting operatively at a lower end to a fixed support while an upper end forms a crank handle (35);
- wherein two rectangular bodies (5) with cylindrical through-holes (13 and 14) are incorporated above the hollow cylindrical body (7) on the upper part of the main body (4);
- wherein the two propellers (15 and 16) are correspondingly arranged in the lower section, while at the top they communicate with a threaded body (17), and an electromechanical/electro-hydraulic piston (18) is solidarity linked to the main body (4) and operatively to the body (11).
