SEED-FEEDING SYSTEM 2 CONSTRUCTED BY BURKOV LN Russian patent published in 2008 - IPC A01C7/00 

FIELD: agriculture.

SUBSTANCE: seed-feeding system consists of a hopper with two departments for seeds and fertilisers, seed dispensers and fertiliser, and mechanism of seed-rate adjustment. Seed dispensers are rigidly fixed on the underside of the hopper and made as rollers with groves. Department for fertilisers in the hopper is formed by placing a removable wall at an acute angle to the vertical, starting from the middle of the tanker's bottom. Department for fertilisers presents stand alone rectangular sections with L-shaped upper edge. Sections are arranged on coupled U-shaped stands, supported by inclined stands. Inclined stands are evenly spaced at a right angle to coupled U-shaped stands. Fertiliser dispensers are made as rollers, grooves whereat are placed along helical curves to the axis of the roller, and rigidly fixed on the underside of the hopper in the common hull with seed-feeding apparatuses under corresponding department of the hopper. Fertiliser dispensers are equipped with fertiliser rate adjuster. Mechanisms of seed-rate adjustment and fertiliser-rate adjustment are made similar and placed on the opposite ends of the driving shafts of the both apparatuses. Mechanisms of seed-rate and fertiliser-rate adjustment consist of hydro-pneumatic 2-directional operation cylinder with a rod, coming outside from the both end of the cylinder. One end of the cylinder is rigidly connected by a plate with a spring-loaded rectangular indicator. Ball-bearing sliding along the scale is fixed on the underside of one of the ends of rectangular indicator. The scale is rigidly fixed to the flat end of the common hull and is applied parallel to the flat end of the indicator. Indicator enters into the vertical slot of the hull, placed on the cylinder. Other ends of guide bars of hydro-pneumo cylinders of seed and fertiliser-rate adjusters are rigidly connected with the corresponding rollers.

EFFECT: provision of complete cleaning of the fertiliser department of the hopper and increase accuracy of adjustment of fertilisers dispensing-rate.
