  • the connection pin 23 is rivet-shaped with a head 23a that is hemispherical on at least the earth auger side.
  • the head 23a is hemispherical, but the shape of the head 23a may be spherical.
  • This jig is an earth auger jig for directly gripping with a grapple 17.
  • This jig requires the following structure. (1) Since the grapple 17 is a device for gripping a cylindrical utility pole, the gripping portion 21 must be cylindrical so that it can be gripped by the grapple 17. (2) At least the lower side (earth auger side) of the head 23a of the connection pin 23 is semi-spherical in shape so that the connection portion 22 is semi-movable with respect to the gripping portion 21. With this structure, when the jig is gripped by the grapple 17, the weight of the earth auger 15 makes the longitudinal direction of the earth auger 15 perpendicular to the ground (perpendicular to the horizontal plane).
  • connection portion 22 There are two or more connecting pins 23 so that the earth auger 15 rotates when the grapple 17 rotates.
  • a conventional pin fastening structure 24 is adopted for the connection portion 22.
  • the earth auger 15 is attached to the connection portion 22 by a pin 26 as shown in FIG.
  • the jig preferably has the following structure: (5) All or all but one of the holes 21a of the grip portion 21 are elliptical, oval, or long polygonal in the longitudinal direction of the grip portion 21.
  • Fig. 5 is a diagram for explaining the definitions of (A) an oval and (B) a long polygon.
  • An ellipse is a shape formed when a circle is cut at one diameter and there are four cut points (a1, a2, a3, a4), and the cut points a1 and a3, and the cut points a2 and a4 are connected by two parallel line segments (ls1, ls2).
  • a long polygon is a regular polygon (a regular octagon in FIG. 5) with an even number of vertices of four or more, in which the length of one pair of opposing sides (re1, re2) is longer than the other sides.
  • the range in which the earth auger 15 is perpendicular to the horizontal plane under its own weight (the allowable range of inclination of the gripping portion 21 when gripped by the grapple 17) can be expanded.
  • All holes 21a may be elliptical, oval, or rectangular, or holes 21a other than one hole 21a may be elliptical, oval, or rectangular.
  • FIG. 6 is a diagram explaining the procedure for attaching the earth auger 15 to the heavy equipment 10 using this jig.
  • This jig is composed of a gripping part 21 and a connection part 22.
  • the gripping part 21 is cylindrical in shape so that it can be gripped by the grapple 17 attached to the heavy equipment 10, and has a hole 21a for connecting to the connection part 22.
  • the connection part 22 has a connection pin 23 for connecting to the gripping part 21, and has a pin hole 26 for connecting the earth auger 15 with a pin.
  • the grapple 17, heavy equipment 10, and earth auger 15 are commercially available products.
  • FIG. 7 is a diagram for explaining the relationship between the head 23 a of the connection pin 23 and the hole 21 a of the grip portion 21 .
  • the head 23a of the connection pin 23 is hemispherical so that the connection part 22 can be suspended in a semi-fixed state from the hole 21a of the grip part 21.
  • the inner diameter d1 of the grip part 21 is 15 cm to 30 cm.
  • the diameter d2 of the head 23a is 5 cm to 15 cm.
  • the width of the hole 21a (the width in the direction perpendicular to the longitudinal direction of the hole 21a) at its widest point does not exceed the diameter d2. This is to prevent the head 23a from falling out of the hole 21a.
  • Figure 8 is a diagram explaining the process of excavating a post hole 51 using this jig.
  • Figure 8 (A) explains the excavation process when the long axis direction of the gripping part 21 can be kept parallel to the ground 50 (parallel to the horizontal plane).
  • the rotation is transmitted to the connection part 22, causing the earth auger 15 to rotate, and the post hole 51 can be excavated.
  • Figure 8 (B) illustrates the excavation process when the longitudinal direction of the gripping portion 21 cannot be kept parallel to the ground 50 (parallel to the horizontal plane).
  • the positional relationship between the connection pin 23 of the connection portion 22 of the jig and the hole 21a of the gripping portion 21 changes, so that the earth auger 15 becomes perpendicular to the horizontal plane due to its own weight. Therefore, by rotating the grapple 17, the rotation is transmitted to the connection portion 22, and the earth auger 15, which is perpendicular to the horizontal plane, rotates, and the post hole 51 can be excavated.
