SOWING MACHINE Russian patent published in 2007 - IPC A01C7/04 

FIELD: agriculture mechanical engineering.

SUBSTANCE: sowing machine comprises housing provided with the hopper for seeds. The housing receives the vertical cell member mounted at the axis of the housing and used for sampling seeds. The sowing machine is additionally provided with the roller-deflector, device for displacement of seeds from the cells, and controller of cell depth. The member for sampling seeds is made of a hollow round thick-walled cylinder freely mounted on the axle. The cells of the cylinder are arranged radially in the transverse plane on their side. The controller of cell depth is mounted in the space of the cylinder extending from the zone of seed charging to the sowing zone. The controller is made of a round sector whose diameter does not exceed 0,999 of the inner diameter of the cylinder. The sector is mounted at the axis of the cylinder with an eccentricity and can rotate around its axle. The axle is set on the housing for permitting rotation with the axis of rotation of the cylinder. The device for displacing seeds from the cells is made of a sprocket mounted in the bottom section of the cylinder space. The teeth of the sprocket engage the cells of the cylinder.

EFFECT: enhanced efficiency.
