SYSTEM FOR ADJUSTMENT OF RIGIDITY OF ATTACHMENT OF WORKING SECTIONS OF CHISEL-DISK TOOL Russian patent published in 2024 - IPC A01B61/04 A01B63/32 A01B49/02 

FIELD: agriculture.

SUBSTANCE: system for adjusting the attachment rigidity of the working sections of the chisel-disk tool includes a hydraulic system consisting of hydraulic hoses with connecting couplings, made in the form of tees, a pressure gauge assembly, hydraulic accumulators, hydraulic cylinders installed on each post of the working section of the chisel-disk tool. On the post of the working section of the chisel-disk tool there is an accelerometer with a valid range of linear operation of not less than 10g and a frequency range of 8–11 Hz for registration of values of horizontal accelerations of section in longitudinal direction with sensitivity error of not more than 1.7% in full temperature range of -16–65 °C. Pressure gauge assembly with hydraulic valve is equipped with servo drive system Ya-AVO01, which allows reducing pressure in hydraulic system with minimum pitch of 0.07–0.09 bar and connected to control system by means of electric wires. Control system is powered from the tractor mains and consists of a power supply unit and an ESP8266 microcontroller.

EFFECT: automatic adjustment of pressure in hydraulic system of working sections of tillage tools to resonance mode of operation is provided with maintenance of this mode at varying physical and mechanical characteristics of soil background.
