SOWING DEVICE FOR SPROUTED PUMPKIN SEEDS Russian patent published in 2016 - IPC A01C7/16 

FIELD: agriculture; machine building.

SUBSTANCE: sowing device for sprouted pumpkin seeds includes cellular driving disk installed at angle to horizontal plane, which cells are made in shape and size of sown crop seeds and are arranged in groups on peripheral part. Number of cells in the group is equal to number of seeds, sown into seat. At that, cellular drive disc is made in form of hollow truncated cone, in side walls of which cells are made and arranged along cone generatrices. Latter is mounted on hub above conical base with possibility of hollow truncated cone with cells rotation relative to cone base. Hollow truncated cone with cells rotation drive shaft is installed at angle ensuring position of generatrices at the angle of friction sliding of soaked and sprouted sown crop seeds and is fixed in base hub on sliding bearing. Cellular drive disc in form of hollow truncated cone is placed in seed box, which bottom is inclined towards cellular drive disc, which provides seeds sliding to cellular drive disc. Cellular drive disc drive is made through the yoke, fixed on drive shaft with drive via bevel gear. Seed box is fixed on conical base via sealing gasket to ensure placement of soaked and sprouted seeds together with water in the seed box, in which they are soaked. Cellular drive disc is made replaceable to enable cells parameters change for various seeds. In cone base upper part a sowing window is made, in front of which a brush-reflector of extra seeds is installed above cellular drive disc, behind which a roller pusher with rollers of elastic material is installed.

EFFECT: higher accuracy of sowing while seed material saving.
