Definitions

  • the present invention relates to a device for drilling soils making square or rectangular holes.
  • augers adapting to the lifting coupling of tractors or any other coupling fitted on vehicles, as well as portable augers, said augers are rotated either by means a bevel gearbox coupled to the PTO of the tractors or are driven in rotation by means of a hydraulic or pneumatic rotor or by means of an internal combustion engine, this kind of augers allows drilling of sections circular which requires to transform the circular section into a square section to intervene manually and this to correspond to certain standards, this said transformation is not always carried out over the entire height of the drilling and it is laborious and long.
  • the invention aims to overcome the drawbacks described above.
  • the subject of the invention is a device adaptable to augers intended for drilling the soil supported by the lifting hitch of tractors or any other hitch or mobile support fitted on vehicles as well as on portable augers driven in rotation by mechanical means
  • said device for performing square or rectangular section drilling is characterized in that it comprises a parallelepiped frame whose four vertical angles delimiting the section of the hole to be made are uprights in angles their wings facing two by two, the latter in the lower part are connected to each other by horizontal crosspieces and are extended by removable knives, in their upper part and intermediately each upright has spacers aligned with the diagonals of the chassis allowing each to maintain a vertical support in the upper part of which is fixed at least one bearing support axis and in the lower part a collar intended to enclose the central rod of the auger.
  • the bearings integral with the axis or axes arranged in a quadrangular manner are either sandwiched between two horizontal circular plates in the case of a single bearing at each angle or in the case of two bearings at each angle, the latter enclose a horizontal circular plate, the or the circular plates in their center are extended in the upper part by a hollow sleeve of square section intended to fit into the outlet square of the auger drive unit and in the lower part by a square axis receiving the sleeve of the tail auger.
  • the concentric rolling surface at the periphery of the plate or plates has on each face of the plate or plates corrugations according to sinusoidal curves, said corrugations having the effect of causing during the rotation of the auger a vertical reciprocating movement of the chassis in order to generate a buffering and shearing effect of the soil around the hole when the auger penetrates and thereby squaring said hole.
  • the device adaptable to augers comprises a parallelepiped frame 1 whose four vertical angles delimiting the section of the hole to be made are uprights 2 in angles their wings facing two by two, each upright 2 in the lower part is connected by a horizontal crosspiece 3 also serving to maintain the earth during the drilling, the latter may possibly constitute a box, in the lower part 4 of the uprights 2 of the removable knives 5 extend said uprights 2, the latter have a flared shape relative to the outer faces of the uprights 2 and this so as to clear the angles of the drilling of the chassis in order to facilitate its ascent, to lighten the efforts of the auger and promote the penetration of the chassis 1 into the ground, the cutting edges 5a of the knives 5 have a dipping bias oriented towards the tangent of the hole made by the auger corresponding to the face of the chassis 1.
  • a sheet 2b disposed at an angle and fixed on the wings of each upright 2 extending up to the level of the upper ferrulf
  • each spacer 8 is connected to a vertical support 9 in the upper part of which is fixed a bearing axis 10, its part lower being connected to a circular collar 12 intended to enclose the central rod 13 of the auger 14.
  • Each bearing 11 is sandwiched between two circular and identical horizontal plates 15, the latter are extended in the upper part by a hollow sleeve 16 receiving the axis square of the drive device not shown, in the lower part by a square axis not shown receiving the sleeve of the tail of the central rod 13 of the auger 14, the concentric zone around the plates 15 on which the bearings 11 rest , has undulations 17 according to identical sinusoidal curves alternated on each face of the plates, the number of undulations 17 in hollow and at the top is gen generally for each of the number of four distributed symmetrically, it goes without saying that a greater number of corrugations can be provided, the latter being in number multiple of four.
  • Said undulations 17 have the function during the rotary drive of the auger 14 to cause an alternating vertical movement of the frame 1 so that during the penetration of the auger 14 into the ground said reciprocating vertical movement generates a buffering effect and shearing of the ground by the knives 5 and thereby facilitates the squaring of the hole and the penetration of said chassis 1.
  • each vertical support 9 the fixing of two axes 10 each receiving a bearing 11, said bearings 11 enclosing a single circular plate horizontal 18 the latter having the same extensions as previously described as well as alternating corrugations 17 on each of its faces.
  • chassis so as to be able to vary the spacing of the vertical faces and this by means of crosspieces 3 and spacers 8 by means of constituent elements which are assembled together by bolts. and this in a known manner.
