SET OF DEVICES FOR SELECTION OF VERTICAL SOIL MONOLITHS Russian patent published in 2014 - IPC G01N1/04 E02D1/04 

FIELD: agriculture.

SUBSTANCE: set of devices for selection of vertical soil monoliths comprises a k number of thin-walled metal cylinders-monolith-selectors with tapered lower end of a triangular shape, equal to where i is the number of cylinder diameter (n≥i≥1), n is the number of cylinders of different diameters, k_i is the number of replicates of the cylinder of i diameter (k_i≥3), and is provided with cantledge. The cantledge is made in the form of (m+1) number of metal cylindrical loads of equal diameter with the ability to mount them on each other and on each cylinder-monolith-selector to form the cantledge of cylindrical shape. At that one of the metallic cylindrical loads mounted directly on the cylinder-monolith-selector, is made with a recess of the cylindrical shape in one of its ends, which diameter is equal to the outer diameter of the cylinder-monolith-selector having a maximum diameter of n cylinders-monolith-selectors, and an axis of symmetry coinciding with the axis of symmetry of the metal cylindrical load. In addition, a set is provided with (n-1) washer with outer diameter equal to the diameter of the recess and a thickness equal to the height of the recess in the end of the metal cylindrical load with the ability to mount each of them in the recess, followed by fixation in it. At that the internal diameters of the washers are not identical and equal to the outer diameter of each of the (n-1) cylinder-monolith-selector, making a pair: washer-cylinder-monolith-selector.

EFFECT: improvement of accuracy of determining the properties of soil on genetic horizons of the soil profile, reduction of time for selection of the monolith and labour intensity of work in selection of the quality sample of the soil.
