Definitions

  • Applicant of the present patent application is also owner of EP Application N. 10192563.4 entitled “Device for burying slender elements, such as cables, pipes, ropes, chains, ducts and the like”.
  • the preceding EP application shows and describes a machine provided with wheels and with a motorized cutter which, by rotating about its own vertical axis, moves forward by tracing in the ground the trench in which adapted means, free to rotate about the vertical axis of the cutter, deposit the wire or cable that is carried by the machine and which a roller immediately covers with the soil removed previously by the cutter.
  • the aim of the present disclosure is to solve the described problem by providing a machine that is capable of burying automatically, simultaneously and in the same trench two contiguous portions of the electrical cable used to delimit the work area of a lawn mower robot.
  • the present disclosure provides a machine that can be applied easily to the vertical cutters that are already in use and in particular even to those already provided according to the previous patent.
  • the present disclosure also provides a machine which is economical and simple as well as original and easy to provide and also to be used.
  • FIGS. 1, 2 and 3 are side views of the excavation assembly of the machine provided according to the disclosure and shown herein in three different configurations for use;
  • FIG. 4 is a horizontal sectional view, taken along the line X-X, referred to FIG. 3 ;
  • FIGS. 5, 6, 7 and 8 show schematically four situations of use of the machine according to the disclosure.
  • the movements of the cutter 1 which excavated the trench are followed constantly by said fin 3 which is provided with a duct 4 and a roller 6 having a horizontal axis.
  • the duct 4 descends vertically along the fin and ends in a downward region with a portion that is curved backward in order to deposit on the bottom of the trench the electrical cable 5 that arrives from a spool of the machine while the roller 6 , in addition to closing the trench by pressing onto the cable 5 the soil lifted by the cutter 1 , allows the height adjustment of said cutter with respect to the rolling surface of the roller, in order to be able to arrange it in the active or transfer configuration and also in order to be able to adjust its excavation depth.
  • the roller 6 is pivoted horizontally in a fork, the arm 7 of which can be locked, by virtue of known means 9 , along the vertical guide 8 that is integral with the fin 3 .
  • the aim of the present disclosure is to allow a vertical cutter of the known type to be improved in order to simultaneously bury in the same trench two mutually contiguous portions of electrical cable
  • the vertical cutter according to the disclosure is to be equipped so that the cable of the first portion, the one which in the outgoing leg is simply placed on the ground, can be engaged by the machine on the return leg and be guided into the trench excavated by the cutter together with the second portion that arrives from the spool of the machine and exits from the duct 4 .
  • the two sliding guides 10 are fixed so as to protrude symmetrically at the two sides of the fin 3 , one on the right and one on the left with respect to the travel direction, and can be used alternately depending on whether the machine is on the right or on the left of the portion of cable 5 to be engaged thereto.
  • the sliding guides 10 necessarily have a C-shaped transverse profile in order to be able to accommodate laterally the portion after the engagement thereof in the spiral 10 S that is welded in the front end of the sliding guide 10 , which has a rectilinear part before curving toward the center of the trench where the cable is to be directed, passing between the prongs of a fork 11 which is fixed so as to protrude from the duct 4 and above the sliding guide 12 which, curved concentrically with respect to the nearby curved portion of the duct 4 , has the C-shaped transverse profile open toward the outside of the curve and toward said duct 4 together with which the descent of the cable 5 to the inside of the trench is to be ensured.
  • the arm 13 In order to facilitate the lateral insertion of the cable 5 between the duct 4 and the guide 12 , the arm 13 , to which the guide is fixed, is pivoted horizontally at 14 in order to be able, if necessary, to lift it enough or even rotate it up to the retention clip 15 which, fixed on one face of the fin 3 , keeps the guide 12 raised, preventing it from accumulating soil when it is not in use.
  • FIGS. 5 to 8 in which the buried electrical cable and the one placed above ground are shown respectively with a dashed line and a solid line, show an example of use of the cutter according to the disclosure by means of the following situations:
  • FIG. 5 shows the cutter, in the configuration of FIG. 1 and proceeding clockwise from point A to point B, that has already buried the electrical cable along the entire outside perimeter of the lawn to be delimited;
  • FIG. 6 shows the cutter, in the configuration of FIG. 2 and diverting from the outside perimeter toward the inside obstacle to be circumscribed, from point B to point C, that has deposited a portion of the electrical cable above ground;
  • FIG. 7 shows the cutter, returned to the configuration of FIG. 1 and proceeding counterclockwise from point C to point D, that has circumscribed the internal obstacle with the buried electrical cable;
  • FIG. 8 shows the cutter, in the configuration of FIG. 3 and returning to the external perimeter of the lawn, that has buried the portion DA together with the portion BC located on the same path and previously left above ground.
