DEVICE FOR STUDY OF PHYSICAL AND MECHANICAL CHARACTERISTICS OF SOIL LAYER Russian patent published in 2015 - IPC G01N33/24 

FIELD: agriculture.

SUBSTANCE: device comprises a frame consisting of a steel plate and racks. Two guides are attached to the plate from the bottom, on which the slider is moved with the support plate, connected to the die block through the hollow extension and the thrust bearing. The axis of the die block, passing through the hollow extension, is a mechanism of shear loading of the soil layer. The mechanism of the vertical load of the soil layer is provided with a vibration exciter and a set of loads for transmission of vertical dynamic and static loads, connected through the slide to the support plate to the die block. The synchronisation mechanism of loads provides simultaneous joint application of vertical and shear loads on the die block. In the process of deformation by the die block of the soil layer the registration of the sensor readings of vertical and angular displacement of the die block to the computer is carried out. The registered readings enable to calculate the physical and mechanical characteristics of soil with the program "Registration of linear displacements".

EFFECT: use of device enables to improve accuracy of measurements and testing efficiency and to expand multi-functionality of the tests.
