This plough adapted to be mounted on a railroad tracklaying machine comprises in its plough area members capable of disaggregating and/or thrusting aside the old compact ballast. These members consist of ejectors acting like pistons and extending through apertures formed in the ploughshares; the ejectors movable across the normal direction of travel of the plough under the control are driven by an actuating mechanism imparting a reciprocating motion thereto, and may be replaced by blades disposed beneath, and substantially parallel to, the ploughshares, the actuating mechanism being adapted to impart to these blades a movement substantially of translation along a closed path.

Railroad track relaying machine comprising a plough

A plough to be applied to a machine for rehabilitating a railway track, for performing the operation consisting in displacing the ballast to be renewed. Lateral ejectors are applied to the lower portion of the plough and actuated alternatively for breaking the compact ballast and push the gravel so as to gradually accumulate same on the sides and afford and easy forward travel of the plough for making a relatively deep cutting into which the new ties can be laid without requiring a subsequent sinking thereof. The lateral ejectors are actuated two at a time, one to the right and the other to the left, for compensating side stress. A possible mechanism for actuating the lateral ejectors comprises rockers having unequal arms and actuated by a hydraulic cylinder.
