发明名称 Mine clearer has support with roller made from used tyres, long handle and shields
摘要 The mine clearer consists of a support (1) for a roller (2) made from a series of used vehicle tyres joined together by bolts (7) through their side walls. The ends of the roller are closed by flanges, and it is weighted with rocks, pebbles or shot. The roller is connected by a long handle (2) with a wheel (8) to a crossbar (6), and the clearer is fitted with shields (4) over the roller and in front of the crossbar. In a variant the roller tyres can be replaced by plates vibrated by electric motors.
