BUNCH SOWING DEVICE FOR SPROUTS Russian patent published in 2016 - IPC A01C7/16 

FIELD: agriculture.

SUBSTANCE: socket sowing device for sprouts comprises a cellular driving disk installed at an angle to a horizontal plane. Disc cells are made according to the form and size of the seed crop and placed at the peripheral portion by groups. Number of cells in the group is equal to the number of seeds, sown into the bunch. Cellular disc in the area of cells location is corrugated, and the cells are arranged on the outer side of the corrugation, height of which is greater than the maximum width of a sown crop seed. Cellular disc rests on a wavy pan, upper surface configuration of which corresponds to parameters of corrugations of the cellular disc. In upper part of wavy pan there is a sowing window, conjugated with a seed tube. In the area of the sowing window above the cellular disc there are roller ejectors, made from elastic material, ahead of which there is a brush reflector of extra seeds. Cellular disc drive is made via bevel gear from the support-driving wheel of the seeder. Drive shaft of the bevel gear is fixed in the support hub of the wavy pan with slide bearing, in front of which there is a seal to prevent water leakage. On the cellular disc the drive hub with square cross-section is fixed, and the drive shaft is fixed in the drive hub by means of a nut.

EFFECT: invention provides higher accuracy of sowing while reducing damage of seeds.
