SOIL-WORKING BLADE WHICH IS INTENDED, IN PARTICULAR, FOR A BLADE-BEARING CHASSIS, AND TIP FOR ONE SUCH BLADE

摘要

The invention relates to a blade (1) for a blade-bearing chassis, comprising at least one blade body (2) which can be fixed to said chassis. The aforementioned blade body (2) comprises at least one working part (3) which is vertical or which is slightly inclined laterally in relation to the vertical plane that is parallel to the axis of advancement (XX') of the blade (1). Moreover, a heel (4) is provided on at least one of the sides of the lower section of the working part (3), said heel being disposed at a positive angle to the ground and being equipped with a tip (5) which is offset laterally in respect of the front edge (6) of the working part (3) of the body (2) of the blade (1). The above-mentioned tip (5) takes the form of a long body, and a front cutting edge (7) is provided at the front part thereof. The blade is characterised in that the rear part (8) of the tip (5) rises up in the direction of the area in which the blade (1) is fixed to the chassis and in that said part (8), together with the front part of the tip (5), forms an obstacle during the advancement of the blade (1), by serving as an abutment to the strip of land that is raised by the front part of the tip (5).
