The global humanitarian problem of mine clearance is unsatisfactorily resolving by the world community. The intra-soil system is proposed for mine clearing by compulsory blasting. The system consists of a group of demining devices. The grouping of demining devices is based on transportation unit. The demining device consists of the flat vertical frame of two segments, is supplied with reducer, drive with power block, control unit, transport hitch with pins, electro-mechanical sensor of transportation unit manipulator position. Segments of a frame are connected among themselves by spigot connection. On the forward segment of a frame are installed rotor gear chisel which contains a disk of chisel, ring chisel, basic and aligning gear wheels. On a back segment of a frame is mounted the vertical positioning wheel of a drive. Ring chisel is supplied with the cutting bodies directed to an external surface of a ring chisel. Transport unit comprises a manipulator for every demining device. Manipulator is equipped with seizure. With the help of the manipulator a device is brought into the operating position, and returned to the transport position. The transport unit is provided with stops that fix the device in the transport position.
The device in the operating position is almost completely submerged in the soil and moves through a minefield, cutting the gap in the soil. When on the course of device there is a mine, the teeth of ring chisel pull the mine out from an installation site, eject forward and mechanically trigger the detonator of mine. According to the operation time of detonator the mine blasts. After the blow form the ring chisel the mine flies away forward and up till blasting. The explosion center is at a distance from the device, weakens the impact of a shock wave on the device and reduces a probability of its damage in result of mine blasting. The metal and energy consumption of device is low, the factor of mine clearing high, the system is reliable. Technology has a triple purpose – a) robotics, b) deserted mine clearance, c) favorable prerequisites for further humanitarian use of the area for recreational and agricultural purposes.
