Definitions

  • An excavator tool comprising an auger rotatable in a support by a motor, the motor being coupled to the auger through a vibration-generator which will impose a variable rotation on the auger over the rotation imposed by the motor, the generator including a ram coupled to the motor or its shaft and to the auger drive shaft, eccentrically relative to one of them at least.
  • a regulator controls feed of fluid to the working chamber of the ram and discharge of fluid therefrom.
  • the object of the present invention is to provide an improved continuous-motion auger.
  • an excavator tool comprising a support, an auger mounted rotatably with respect to the said support, a motor for driving the auger in rotation, linked between the support and the auger, and a vibration-generator interposed between the support and the auger, which in operation generates a vibratory rotational motion coaxial with the main rotation of the auger
  • the generator comprising a fluid-operable ram having at least one working chamber, and means for placing the chamber alternately in communication with a source of fluid under pressure and with a discharge tank, the ram being linked between one of the relatively movable elements of the motor, the frame or the output shaft, which is movable with respect to the support, and the shaft of the auger, and eccentrically with respect to at least one of these parts comprising the movable element of the motor and the shaft of the auger.
  • a regulator effects the alternate communication of the working chamber and comprises a central hub linked to the movable element of the motor and inserted in a sleeve fixed with respect to the support of the tool.
  • the ram has one working chamber, two apertures are arranged in the inner face of the sleeve and are connected, the first to the source of fluid under pressure, and the second to the discharge tank, whilst a duct is bored into the hub, which opens in the course of a rotation of one revolution of the hub with respect to the sleeve, during one portion of this rotation into the first aperture and during another portion of the said rotation into the second aperture, and is connected to the said working chamber.
  • FIG. I is an elevation of an embodiment of tool in accordance with the invention.
  • FIG. 2 is a partial axial section of the tool shown in FIG. 1',
  • FIG. 3 is an axial section similar to that of FIG. 2 but illustrating the detail of the vibration-generator; this Figure is moreover a section along the line III-ll] in FIGS. 5, 6 and 7;
  • FIGS. 4, 5, 6 and 7 are sections respectively along lines lVlV, VV, Vl-VI and VII-VII of FIG. 3;
  • FIG. 8 illustrates the diagram of a hydraulic circuit for control of the vibrator-generator illustrated in FIG. 3.
  • the tool illustrated in FIG. 1 comprises a support 1 fixed with respect to the ground and comprising, for example, the end beam of a public works machine.
  • a flange 2 is hinged on support 1 by means of ears 3 integral with the flange and a connector pin 4.
  • a housing 5 of a hydraulic motor is attached by bolts 6 to the flange 2, a flange 5a of the housing 5 being arranged for this purpose which abuts flange 2.
  • Another housing 8 shielding a vibration-generator and furnished with a flange 9 is connected with the housing 5 of the motor by means of bolts 10 and of a second flange 5b of the housing 5 abutting the flange 9.
  • a hub 39 is integral with the plate 26 and is mounted rotatably in and with a seal against a bore 290 in the sleeve 29.
  • the shaft 27 and the hub 39 are maintained axially locked by a bolt 40.
  • the ducts 37 and 38 extend into the hub 39 and emerge through ducts 37a, 38a and 38b facing the bore 29a in the sleeve.
  • a regulator 44 consisting in this instance of the assembly of the sleeve 29 and the hub 39 is linked to the motor with the housing 5.
  • the pipes and 36 are connected respectively to the chambers of the ram 32, of small working section 32b and large working section 320.
  • the regulator 44 has two positions which are alternately selected in the course of the rotation of the shaft of the motor in the housing 5 and which correspond, one to the putting in communication of the pipes 19 and 36, 38, the other to the putting in communication of the pipes 36, 38 and 20.
  • the chamber 32b is permanently in communication with the pipe 19, through the pipes 35, 37 and 370.
  • the auger may equally be subjected to longitudinal vibratory motion which also facilitates its penetration. Finally, the vibrations generated can have forward and return paths of different durations and forms.
  • the communication means includes a regulator operable to alternately connect the chamber to the source and the tank to the regulator, comprising a central hub linked to the movable element of the motor and received in a sleeve fixed with respect to the support of the tool and which includes, when the ram has one working chamber, two
