<p>The invention relates to an intelligent sowing device meant for precision sowing machines using various types of seeds, especially for sowing machines equipped with pneumatic distributors. According to the invention, the device consists of a control unit (UCC), a seed tube (b), a photo-electric sensor (1) and a light source (2), all of them mounted on the disk (a) of a sowing machine with pneumatic distribution, so that the light source crosses the holes of the rotation disk and activates the photo-electric sensors (3 and 6) of the light source, mounted on the tube (b), the pneumatic electrovalves (5 and 8) provided, at one end, with some sieves (4 and 7, respectively), some tubes (c and d), positioned in a right angle, which are provided at the lower side with the normally closed electromagnetic vane valves (9 and 12), comprising the electromagnet (11) with the return spring (10) and the electromagnet (14) with the return spring (13), a bifurcated channel (f), a box (h) and an elevator (g).</p> |
