Development of a heavy demining machine

Heavy demining machines are intended for humanitarian demining of larger mine-suspected areas. Two combinations of tools were considered herein: a working tool with two-flails, and a design with one flail and one tiller, and analyze the function of these variants. Some time ago, it was unimaginable to combine a flail and tiller, mostly because power demands were too high. Nonetheless, by suitably allocating the power to the working tools a realistic option was designed, which should be feasible even for smaller sized machines. In order to destroy AP and AT mines, the primary role is given to a flail of high diameter, and a backup function to the tiller whose diameter is two times lower. The depth and rpm of the tiller may be controlled independently of the flail, which ensures that digging depth is good enough. With two independent and different tools the density of hammer strikes is immediately adaptable to the conditions of mine density at different depths. The required force of the hammer impulse is determined in order to be able to overcome the resistance from digging the soil resistance. Furthermore, the independence of tool adaptation together with remote control improves the speed of mine clearing. A high reliability of mine destruction is thereby ensured. The results of machine testing show high graded performance regarding mine-clearance quality.
