SYSTEM FOR ADAPTATION OF WORKING SECTIONS OF CHISEL-DISK TOOL TO RESONANCE MODE OF OPERATION Russian patent published in 2025 - IPC F15B15/00 A01B61/04 A01B63/32 A01B49/02 

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machine building and can be used for automatic adjustment of working sections of chisel-disk tools to resonance mode of operation. System for adaptation of working sections of a chisel-disk tool to a resonance mode of operation 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, at that, 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 10 g and a frequency range of 8.5-8.9 Hz for registration of values of horizontal accelerations of section in longitudinal direction with sensitivity error of not more than 1.8% in full temperature range of -14.5...-15 °C, pressure gauge assembly with a hydraulic valve is equipped with a servo drive system Ya-AVO01, which enables to reduce the pressure in the hydraulic system with a minimum pitch of 0.08-0.085 bar and connected to the control system by means of electric wires, wherein control system is powered by tractor electric circuit and consists of power supply unit and ESP8266 microcontroller.

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