MACHINE FOR EXTRACTION OF TOMATO SEEDS FROM BREEDING BATCHES Russian patent published in 2024 - IPC A23N15/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building and can be used for extraction of tomato seeds from breeding batches. Machine contains a frame, an electric motor, a V-belt transmission, a hopper, a shaft, an auger, flails, a sieve, a casing, a shield, a collector, a tray of separator sections and a seed separator. Sections of separator and seed separator are installed on common frame and equipped with drives of drive shafts through V-belt transmission from one electric motor. Separator drive shaft accommodates auger, propeller and blades. Auger is cone-shaped and has trapezoidal cut-out segments. There is an inclined semi-conical bottom under the auger. Propeller is different-flange two-bladed. Two pairs of serially arranged flail bars with holes for fastening elastic pads are fixed on spiral brackets with fixed advance angles. Propeller and flails are located in sieve cylinder. Frames are equipped with a pair of fixed square cross-section contractors located towards each other between the propeller and the flail plates. Seed separator has a cylindrical auger on the drive shaft and a sieve semi-cylinder under it. Four flails are installed in pairs on fixed bracket and movable bracket for adjustment of advance angle. Separator and seed separator have unified cylindrical sieves differing in size of hole. Rotation frequency of shafts of their drives is controlled and is different through the established diameters of the double-strand pulley of the separator, the single-strand pulley of the seed separator and the three-strand pulley of the electric motor.

EFFECT: use of the invention will make it possible to increase efficiency of seeds extraction.
