FIELD: physical-mechanical measurements.
SUBSTANCE: device can be used for continuous registration of hardness of soil layers during basic treatment of different types of soil, during cultivation and fertilization and/or melioration. Device for continuous measurement of hardness of soil has motor-transportation aid provided with engine, forced gas-turbo-supercharging, supercharging pressure detector connected in series with functional converter and analog-to-digital converter, soil hardness meter, coupling set point device, indicator, crankshaft frequency of rotation detector and tachometer. Output of analog-to-digital converter is connected with first input of soil hardness meter, which has output connected with indicator. Second input of soil hardness meter is connected with coupling set point device. Crankshaft frequency of rotation detector is connected with tachometer.
EFFECT: higher speed of operation; reduced labor input.
