SOWING DEVICE FOR BED SOWING OF SWOLLEN AND GERMINATED SEEDS Russian patent published in 2011 - IPC A01C7/16 A01C7/18 

FIELD: agriculture.

SUBSTANCE: sowing device comprises a sowing conveyor with cells and active guides arranged on the conveyor. Active guides have height equal to minimal thickness of a sown crop seed. At the same time length of active guides at one side of the cell is more than at the other by value equal to the average length of a sown crop seed. The sowing conveyor is installed in the side wall of a seed box and is arranged as a hollow cylindrical drum. The drum is installed on bearings, which have glands to prevent water leakage. Cells are located on the side surface of the drum and are shaped and sized same as sown crop seeds. At the same time the cells depth is equal to the average thickness of the seed. The bottom of the cells has a slot connected to water draining grooves, which also serve as guides for pusher rolls. The pusher is installed on a spring-loaded lever in the upper part of the seed box, which is coupled with the receiving vortex of a seed duct. The bottom of the seed box is inclined towards the cylindrical drum, and the seed duct is arranged with ribbed walls. Air or gas with head providing for seeds transportation along the seed duct is supplied by means of a nozzle to coupling of the seed box and the seed duct funnel.

EFFECT: invention makes it possible to increase productivity and technical reliability of swollen and germinated seeds sowing.
