CULTIVATOR SECTION WITH OSCILLATION GENERATOR Russian patent published in 2025 - IPC A01B35/20 A01B35/32 A01B63/12 A01B61/04 

FIELD: agriculture.

SUBSTANCE: cultivator section with oscillation generator includes post (1) with duckfoot (2) hingedly (3) fixed on frame (4) by means of lower and upper brackets (5 and 6) connected by an elastic element in the form of cylindrical spring (7), equipped with screw adjustment mechanism (8). Vibration generator of eccentric type (9) is rigidly fixed on post (1) of duckfoot (2). Vibration acceleration sensor (10) with operating temperature range of -55…+85 °C, operating frequency range 3…650 Hz, acceleration range 0.2…85 m/s² is rigidly fixed under duckfoot (2), which transmits a signal to the automated control unit of system (11) for controlling the frequency of additional disturbances on eccentric-type oscillation generator (9), which is required to introduce post system (1) and duckfoot (2) into the resonant operating mode. Eccentric-type oscillation generator (9) consists of a DC motor with degree of protection IP54 and a shaft on both sides of which two eccentric weights are fixed. Stiffness of elastic element (7) is adjusted to generate frequency of natural oscillations of cultivator section corresponding to oscillations of soil reaction within 8.2…12.2 Hz.

EFFECT: enabling reduction of energy consumption during soil cultivation operations due to use of dynamic effects in the process of interaction of the working tool with soil.
