Title: Penetrating machine
Claims: What is claimed is: 1. A perforating machine for forming rows of holes in the ground comprising: a perforating roller which is adapted to roll on the ground and whose peripheral surface carries perforating tubes mounting for pivotal movement about axes extending parallel to the axis of the roller in such a manner that from the beginning to the end of their contact with the ground their axes remain substantially perpendicular to the ground, at least a part of the periphery of the roller being enclosed by guide means for intercepting plugs of earth formed by the perforating tubes. 2. A machine as claimed in claim 1 including a collecting vessel mounted for lateral tipping on a frame joined to the body of the roller and disposed in front of the roller in the direction of travel of the latter. 3. A machine as claimed in claim 1 including guide plates forming a polygonal body disposed in the interior of the roller. 4. A machine as claimed in claim 3 in which outlet slots are provided between the guide plates. 5. A machine as claimed in claim 3 in which the guide plates are pivotally mounted. 6. A machine as claimed in claim 1 including perforating tube carriers for carrying the perforating tubes, each perforating tube carrier being in the form of a square-section bar mounted in a reset, an abutment being provided to limit pivotal movement of said bars. 7. A machine as claimed in claim 1 including transport wheels which can be moved to a transport position by a power drive. 8. A machine as claimed in claim 1 in which the perforating tubes of two adjacent rows of perforating tubes are staggered relative to one another. 9. A machine as claimed in claim 1 including a spring comb whose teeth extend rearwards under the perforating roller and lie between the perforating tubes. 10. A machine as claimed in claim 9 including spring means for urging said teeth into contact with the ground, said spring means being adjustable. 11. A machine as claimed in claim 9 in which the teeth are sprung individually or in pairs in the longitudinal direction. 12. A machine as claimed in claim 9 in which the teeth are inserted into holes extending parallel to one another in a square section carrier which is secured, for axial adjustment, on two lateral carrier arms, coil compression spring means being disposed between the square-section member and a projecting end of the teeth. 13. A machine as claimed in claim 12 in which an L-section member, which forms an abutment for the projecting ends of the teeth, is attached to the square-section member. 14. A machine as claimed in claim 12 in which the square-section member is fastened on the carrier arms by means of damping means so as to be angularly adjustable. 15. A machine as claimed in claim 12 in which the teeth are formed in a U-shape as pairs of teeth. 16. A machine as claimed in claim 9 including a plurality of hose means through which seeds and/or fertiliser are discharged from a container between the teeth at a position behind the perforating roller in the direction of travel. 17. A machine as claimed in claim 16 in which an inlet end of each hose means is provided with a feed funnel above which is disposed an outlet slot of a spreading device provided with a metering roller. 18. A machine as claimed in claim 16 in which the hose means are transparent.
