DRILLING MECHANISM Russian patent published in 2007 - IPC A61C7/16 

FIELD: agricultural engineering.

SUBSTANCE: invention can be used for seeding melon cultures. Proposed mechanism includes driven cellular disk with groups of cells formed over periphery. Cells are made in form of seeds to be planted. Jumpers in form of active guides are made at sides of each cell. Cellular disk is installed vertically in sealed seed box. Cells and active guides are arranged on turnable blades. The latter are mounted on disk over periphery by means of axles and are fixed at angle of 40-50° to disk plane by means of stop. Blades are equally spaced over disk periphery. Axles of blades are provided with pull-back springs. Each blade carries group of cells whose number is equal to number of seeds to be planted simultaneously in hollow. Center of cell on peripheral part of blade is displaced backwards from center of inner cell to value equal to length of seed of planted crop. Active guides of equal to 1.5-2.0 mm and height in fractions of 0.7-0.9 of seed thickness are arranged between cells. Drain hole is provided on bottom of each cell. Upper part of seed box is provided with turnable projection found before seed hole.

EFFECT: possibility of planting soaked and germinated seeds without damage.
