DEVICE FOR MEASURING SOIL HARDNESS Russian patent published in 2023 - IPC G01N3/40 

FIELD: measuring equipment.

SUBSTANCE: invention relates to instruments for measuring physical properties of soils. The device contains a handle, a cylindrical spring with plates, a rod with a calibrated tip, a platform for paper with paper, and a support shoe. On the handle, there are additionally a guiding sleeve for the rod, a vertical bracket with a tape measure, a horizontal bracket with a video camera, a vertical ruler, and a limiting bar.
