DOUBLE DRUM GRANULAR FERTILIZER SPREADER Russian patent published in 2023 - IPC A01C17/00 

FIELD: agricultural engineering.

SUBSTANCE: agricultural engineering, devices for distributing granular fertilizers over the soil surface. Granular fertilizer spreader includes a frame and a body with a divider installed on the running system and a belt conveyor located in the bottom, a central spreading disc fixed on the frame behind the body between two fertilizer spreaders, and control dampers. A low-sided body is mounted on the frame in such a way that with a road clearance of 500 mm from the field surface, the upper border of the sides is at a height of 1100 mm from the field surface. Fertilizer spreaders are made in the form of drums with unloading windows and dosing holes, represented by casings with rotary bladed throwers with a mechanical drive installed inside. At the same time, the adjusting dampers are installed in the area of the dosing openings of the casings of the vane throwers, and removable adjustable parabolic deflectors are installed above the unloading windows of the casings of the vane throwers to adjust the uniformity of the flow of spread fertilizers. The divider has a mechanism for adjusting the supply of the introduced material to the rotary vane throwers and the spreading disc.

EFFECT: invention will improve the uniformity of the distribution of fertilizers and reduce the time for loading fertilizers.
