SECTIONAL CUTTER OF DISPENSER AND AGRICULTURAL MACHINE THAT CONTAINS IT Russian patent published in 2013 - IPC A01C7/08 A01C15/04 

FIELD: agriculture.

SUBSTANCE: agricultural machine for application of a material in soil consisting of seeds, fertilisers or seeds and fertilisers comprises a central frame and multiple extended mounting arms attached to the central frame. Each of the mounting arms is movable from a raised transport position to a lowered working position of the soil tillage facility mounted on each of the mounting arms adapted for tillage of soil, when the mounting arms are in the working position. Facilities for release of the material at each of the mounting arms are located near the soil tillage facility for application of the material into the soil. Facilities for release of the material are connected to dispensing facilities adapted for distribution and dispensing of the material into the facilities of material release on each of the mounting arms. Additionally the device comprises a mapping unit of the satellite navigation systems GPS and GLONASS, and the facility for closing the flow of material from the selected material of the dispenser during operation of the machine in response to an input signal received by means of the satellite navigation mapping system GPS or GLONASS. When the mapping unit of the satellite navigation system determines that the specified plant or a part of the specified plant extends over an area of soil, to which the specified plant has already applied the material, the facility for closing the flow of material cuts the material flow from the selected dispenser of the material through the automatic device of lifting of the specified mounting arms, to which the material supply from the selected facility of material release was blocked, into the raised position, as the specified mapping unit of GPS and GLONASS identifies areas, where this agricultural unit has already passed, and where the specified materials have already been applied.

EFFECT: invention will prevent duplication of planting and destruction of already planted beds.
