SELF-LOADING SPREADER OF FERTILISERS Russian patent published in 2009 - IPC A01C17/00 

FIELD: agriculture.

SUBSTANCE: self-loading spreader of fertilisers consists of load-lifting device, bin-feeder and spreader. Bin-feeder by means of frame is pivotally installed on force rods of mounted tractor's hydraulic system. Inside the bin it is located supporting frame with fixed on it pyramidal tetrapetalous knife. Supporting frame is outfitted by throwaway members with profile clothing and installed on articulated suspension brackets, one ends of which are fixed on frame and other ends - on walls of bin with formation of articulated semirevolving four-link mechanism. Supporting frame with pyramidal knife allows power mechanism for directed return motion. One of pairs of co-axial suspension brackets of four-link mechanism allows common shaft. Shaft supports are located on walls of bin. One end of shaft allows cantilevered section and transcending bins. On cantilevered section it is fixed crank, to which it is connected drive of oscillating travels of supporting frame. Power mechanism corresponds hydraulic actuator of double-acting with built-in in its body valve. Rod of hydraulic actuator is pivotally connected to shaft crank, and body is pivotally fixed on frame of bin. Crank is connected to controlled reactive spring.

EFFECT: productivity improvement and conditioning of its operation.
