Abstract
Abstract The track perforator has a share pointing backwards and downwards, and suspended at the bottom of a shaft via screws and springs. One both sides of the share are fitted two staggered plates. The distance between the double plates is greater towards the free outer ends. The rear edge (19b) to the front edge (19a) of the front top share (19) is thinner towards the free outer side. The front edge (18c) of the share (18) runs further back with respect to the front edge (19c) of the soil share (19), which points outwards and upwards.
