SOIL-CULTIVATING FRONTAL COMBINED PIERCING-PACKING UNIT Russian patent published in 2023 - IPC A01B35/16 A01B37/00 

FIELD: agriculture.

SUBSTANCE: soil-cultivating frontal combined piercing-packing unit contains a space frame (1) consisting of profiled tubular rods (2, 3, 4, 5, 6) connected to each other and mounted on gusset stops (7) with power hinges. On the space frame (1) there are beam-shaped decompressing piercing bodies (10) and a loading hydraulic cylinder (12) with a bracket (13) is fixed. The soil-cultivating frontal combined piercing-packing unit contains a press roller (14), which, with its central axis (15), is fixed with a pin stopper in the mounting hole in the lower part of the shock absorbers (17), made in the form of a metal tubular axle with through mounting holes, on which a compression spring is installed. The upper part of the shock absorber (17) passes through a hole in the angle brackets, welded by electric arc welding to the longitudinal tubular rods (5, 6), and is fixed with a pin stopper in the upper mounting hole of the shock absorber (17).

EFFECT: improved water permeability of the soil layer, leveling and compaction of the upper layers of the soil, high-quality preparation of fields for sowing with a single passage of a tillage unit, reduction of the man-made impact of running systems of wheeled tractors on cultivated soils in order to maintain and improve fertility and increase crop yields, increase the productivity of the tractor when using a simple device, which is easy to manufacture, highly reliable, durable, easy to maintain and operate.
