AUTOMATIC CONTROL DEVICE OF WORKING MECHANISM OF SOIL COMPACTING MACHINE Russian patent published in 2014 - IPC E02D3/46 E01C19/28 G01N3/02 

FIELD: construction.

SUBSTANCE: invention relates to construction, and namely to control of compaction of bulk soils. An automatic control device of an actuator of a working element of a soil compacting machine consists of an accelerometer, an amplifier, a band-pass filter, an amplifier with an adjustable amplification coefficient, a filter of the first harmonic, a frequency to analogue signal converter, an algebraic adder, a setting device of a soil compaction degree, an analogue-to-digital converter, a compactor, a trigger, a signal shaper and a memory unit. The device is equipped with monitoring converters of the number of machine passes, its movement speed, force and frequency of an impact of the working element, speed of a bell-crank mechanism, input and output normalisers for connection to a control object, an on-board microprocessor controller with a software, which is controlled with the actuator as per several optimum parameters. Primary converters are electrically connected through the input signal normaliser to Input 1 of the microprocessor controller, to Input 2 of which a signal is supplied from a comparison analyser, and control commands of the adjustable actuator kinematically connected to the working element of the machine are shaped from Input through the output normaliser.

EFFECT: higher efficiency of a soil compacting machine; improved quality of compaction of a bulk coating.
