UNDISTURBED SOIL SAMPLING DEVICE Russian patent published in 2023 - IPC E02D1/04 

FIELD: sampling.

SUBSTANCE: invention relates to devices for sampling soils with undisturbed composition (structure) and can be used to extract various types of soil and soil samples in the field for a comprehensive analysis of agricultural land. The device for soil sampling with undisturbed structure comprises an outer cup with a multi-start helical spiral, an inner cup, inside which a hollow element is installed, a sampling element and a handle. It has an electric motor with a control unit and a gearbox, the shaft of which is connected through a coupling to the upper parts of the outer and inner sleeves, while the control unit consists of a power source connected in series, a program relay, a frequency converter with a start button and a speed sensor connected electrically to the program relay and mechanically with a gear shaft. The inner cup has a longitudinal hole for installing a hollow element inside it, made in the form of a removable capsule with a diameter of 3-4 mm less than the inner diameter of the inner cup, formed from two semi-cylinders interconnected in the upper part. The intake element is made in the form of a cutting conical head, in the upper part of which there is a thread for connection with the inner sleeve, and in the lower part it has a protrusion to stop the end of the outer sleeve, and at the end of the conical part it has a cutting edge.

EFFECT: expanding the functionality, reducing labour costs and increasing the productivity of the device for sampling soil with undisturbed addition.
