MACHINE FOR SEPARATION OF SEEDS FROM FRUIT OF CUCURBITS CROPS Russian patent published in 2012 - IPC A23N4/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to devices for separation of seeds from fruit of cucurbits crops. The machine contains a hopper, a device for destruction of fruit placed in it, a device for separation of seeds and pulp separation. On the cylindrical surface of the drum in a device for destruction of fruit in three rows in 120 degrees, the plates are mounted perpendicular to the axis which have the thickness of the working face not less than the width of the seed, with the strengthening on the working face, by one in the row, the plates in the transverse plane. On the concave the plates are installed in the spaces between the trajectories of the passage of the drum plates with smaller thickness and height of the working face. In the device for isolating and separating the seeds on the shaft the plates are fastened along a helical path through 120 degrees, without overlap on the radial racks at an angle to the shaft 3…5 degrees. The cylindrical concave of the device for isolating and separating the seeds is made composite from the semi-cylinders: upper - solid, bottom - from the bar across the axis, placed with a gap. In the bottom the screw of left winding is mounted. The device for pulp separation is made in the form of a shaft with plates reinforced by a spiral line through 120 degrees, an angle of 2…3 degrees, with overlapping, on radial racks and cylindrical shell coaxial with the shaft with circular holes smaller than the width of the seeds.

EFFECT: invention enables to reduce the damage and loss of seeds during their separation from the fruit of cucurbits crops.
