DEVICE FOR SUBSURFACE MEASURING AGROTECHNOLOGICAL CHARACTERISTICS OF SOIL ARABLE LAYER IN MOTION Russian patent published in 2015 - IPC G01N33/24 A01B13/10 A01B79/00 

FIELD: agriculture.

SUBSTANCE: device relates to the field of agriculture, in particular to the technologies of precision agriculture. The device comprises a bearing frame connected to the means of moving on the field, a support element mounted on the frame and determining its position above the ground, the knife-milling chisel plough placed on a frame, creating longitudinal slit channel in the soil during motion, a measuring unit with the measuring sensors, made elongated along the direction of motion, of the same thickness with the knife-milling chisel plough and mounted behind it in the direction of motion, the assembly of stepped depth adjustment of the position of the measuring unit in the longitudinal slit channel when moving on the field, the assembly of protection of the measuring unit from damage by collision of the knife-milling chisel plough to the obstacles, the control unit of measurements, collection and conversion of the measurement information, the on-board computer and the receiver of the geopositioning system for registering measurement information and mapping. And the housing of the measuring unit is made in the form of a monolithic metal plate with a pointed and bevelled downwards and backwards frontal anterior edge and is fixedly connected to the bearing frame by the front and rear racks. The sensors are embedded in the measuring unit and located on its side walls along the common straight line with the same depth of location of the sensing elements from the soil surface. The support element is made in the form of a support skid located under the measurement unit, pivotally connected with the rack mounted on the bearing frame. And this rack is mounted on the bearing frame with the ability of a stepped change in the given distance between the sole of the support skid and the straight horizontal line with the same depth of location of the sensing elements in the measuring unit from the soil surface. The said knife-milling chisel plough mounted on the frame in front of the measuring unit, has an axial connection with the frame, ensuring the formation of a common vertical longitudinal plane of symmetry with the measuring unit and made with the ability to control the angular position of the knife-milling chisel plough in this plane. The knife with the cutting edge has a length that ensures creation of the slit channel in the soil with the depth enough for embedding the measuring unit until it stops of the support skid on the surface of the soil at any given distance between the sole of the skid and the horizontal line of position of the sensors and any specified angle of the knife-milling chisel plough mounting. The upper end part of the knife-milling chisel plough, located on the other side of the axial connection, is fixed by the safety shear bolt in the assembly of stepped fixing of the angular position of the knife-milling chisel plough located on the frame, and this assembly is equipped with a stop for fixing the position of the blade of the knife-milling chisel plough along the frontal measuring unit when collision to the stone and cutting the safety shear bolt, moreover, to retain the measuring unit in the vertical plane of symmetry coinciding with the direction of movement of the device. The bearing frame is provided with a rigid drawbar to connect with the vehicle for motion on the field.

EFFECT: unit provides measurement efficiency of agrotechnological characteristics.
