| 摘要 |
The present invention relates to a method and a device for increasing the clearance effectiveness of such mechanical mine clearing tools (7) that operate on the rotary cultivator principle and which thus incorporate a number of mutually parallel demining discs (9) each one of which should have a number of teeth angled in opposite directions around its periphery. The present invention is based on the fact that impact devices (16) are located between each pair of demining discs (9) and that each said impact device is so designed that when the demining tool (7) cuts through the upper ground layer that is to be demined the ground layer between each two adjacent demining discs (9) is impacted by successive impact devices.
