Plough beds for cable type laying - has shares on both sides whose cutting edges are arranged at acute angle to direction of cut
Реферат: Plough body for the trench-less laying of cable-type pipes, especially flexible drain pipes with shares on both sides, enclosing a prismatic earth breaker where the cutting edges (2) of the shares (1) are arranged at an acute angle and with respect to the direction of cut (7). This angle is such that is does not allow the side breakages of the soil to remain in the soil. An intermediate base joins the shares (1) and at its front edge, this projects beyond the bottom part of the side breakages and is arranged at a slope with respect to the horizontal which permits the breaking up of the soil.
Ploughing device for maintenance of e.g. vineyard, has ground pressing units arranged on both sides of sub-soiling plough tooth above shell and each constituted of skate with ends curved upwards
