Device for shaping a furrow profile, sensing soil properties and dosing fluids

A device for shaping a profile of a furrow, sensing soil properties and dosing fluids in the soil of an agricultural field, comprising:

• a body comprising an upper portion and a lower portion defining a right lateral face and a left lateral face that are laterally opposite, a front face and a rear face that are longitudinally opposite, and an upper face and a lower face that are vertically opposite, wherein the laterally opposite faces at the lower portion of the body are angled relative to a vertical direction forming a V-shaped profile cross section for V-shaping furrows;
• damping and biasing means linked to the upper face of the body;
• at least one fluid dosing conduit comprising an inlet and an outlet, and being longitudinally arranged within the body;
• sensing means on at least one face of the body for measuring soil properties;
• and
• a sensing unit for commanding the sensing means and receiving information thereof,
• wherein the damping and biasing means comprise a coupling arm and a support arm, wherein the coupling arm comprises two parallel and spaced apart bars that are linked to the body at one end and each has a through-hole at another end, and wherein the support arm is between the parallel bars of the coupling arm supporting the latter and has a through-hole collinear with the coupling arm holes, thereby forming together a space that defines a pivoting axis and comprises a rubber bushing or a metal torsion spring.
