MACHINE FOR OVERSOWING GRASSES AND FERTILISER APPLICATION ON MOUNTAIN SLOPES Russian patent published in 2015 - IPC A01C15/00 A01C17/00 

FIELD: agriculture.

SUBSTANCE: machine for oversowing grasses comprises a frame, support wheels, a technological capacity, two centrifugal discs with blades, a fertiliser guide and a metering valve. One of the centrifugal discs is fixed on the hydraulic motor shaft with the ability of adjustment of inclination angle depending on the slope steepness in rotation with respect to the axis under the action of traction and the lever and the hydraulic cylinder rod pivotally interconnected with it. The stroke of the hydraulic cylinder depends on the pressure change in the hydraulic system when movement of the rod of the slide hydraulic valve due to rolling of the roller, mounted on its end, on the straight-line cam of the slider. The latter is moved in turn on the horizontal due to rolling of the roller, mounted on its end, on the straight-line cam of the pusher. At one end of the pusher a gauge wheel is pivotally secured, which has a continuous contact with the soil surface due to the elastic forces of the spring.

EFFECT: invention enables to improve operational reliability and eliminate the possibility of a vehicle turnover when oversowing grasses and fertiliser application on mountain slopes.
