When driving the tube body 10 into the soil, the tube body 10 is driven into the soil up to a reference line 13 provided on the outer peripheral surface of the side wall 11 of the tube body 10.

  Accordingly, as shown in FIG. 12 (c), the distal end portion of the tubular body 10 is driven into the soil to a position below the lower end portion of the soil collecting can 80. And the soil can 80 is inserted in the cylinder part main body 10 through the soil S around it.

  Next, as shown in FIG. 10A, the rotary handle 30 is inserted into the insertion hole 17 of the cylindrical body 10 and is mounted so that the rotary handle 30 extends from both sides of the cylindrical body 10. Then, the operator rotates the rotary handle 30 to rotate the cylinder body 10 with respect to the ground. In the present embodiment, the cylinder body 10 is rotated about 90 ° (see FIG. 12C). In addition, the rotation angle of the cylinder part main body 10 is not limited to about 90 °, and may be any angle as long as the cylinder part main body 10 can be separated from the soil.

  Accordingly, as shown in FIG. 12 (c), the cylindrical portion body 10 is in a state where the contact between the outer peripheral surface of the side wall 11 of the cylindrical portion main body 10 driven into the soil and the soil is separated, and the cylindrical portion body. The soil S inside the lower end of 10 is separated from the lower soil S ′ adjacent thereto, and the tube body 10 can be easily pulled out of the soil. And the cylinder part main body 10 is pulled up via the rotation handle 30 (refer FIG.12 (d)). When the tubular body 10 is pulled up, the soil can 80 is inserted into the tubular body 10 through the soil S whose entire outer peripheral surface is hardened. There is no risk of falling off from the tube body 10. Then, the support member 40 is inserted into the tube portion main body 10 from the upper side of the tube portion main body 10, the tube portion main body 10 is turned upside down, and the tube member main body is supported by the support member 40 as shown in FIG. 10 is supported in a standing state (third step).

  When the tubular body 10 is pulled out from the soil, as shown in FIG. 10 (c), the soil collecting can 80 is pulled out together with the soil S, so that the soil in the soil can 80 can be reliably affected. Can be dug into.

  Next, the cylinder body 10 is pressed downward against the support member 40, and the upper end of the soil can 80 is positioned above the upper end of the cylinder body 10. Then, as shown in FIG. 11, excess soil at the upper end of the soil collecting can 80 positioned above the cylindrical body 10 supported by the support member 40 is shaved with a spatula 60 or the like, and the upper end of the soil can 80 is After shaping the end face, a lid 83 is attached to the upper end portion of the soil can 80 (fourth step). In addition, description of the cover part 83 is abbreviate | omitted in FIG. Therefore, when shaping the end face of the soil collecting can 80, the end face faces upward, so that the possibility of soil spilling from the end portion of the soil collecting can 80 can be reduced.

  And the cylinder part main body 10 is further pressed below with respect to the support member 40, and the soil can 80 is taken out from the cylinder part main body 10 (5th process). In addition, as described above, since the soil collecting can 80 is inserted into the cylindrical body 10 through the hardened soil, the soil collecting can 80 may not be easily removed from the cylindrical body 10. . In this case, the soil S outside the soil collecting can 80 is removed through the hole 15 provided in the side wall 11 of the tubular body 10. Therefore, the soil collecting can 80 can be easily taken out from the cylindrical body 10.

  In addition, as described above, when collecting the soil collecting can 80 from the soil, the tube body 10 is driven into the soil so as to surround the soil can 80, and the tube body 10 is rotated and pulled up. The soil can 80 can be recovered from the inside. Further, the earthmoving can 80 can be taken out of the cylinder part body 10 simply by moving the cylinder part body 10 with respect to the support member 40. For this reason, the soil can 80 can be easily recovered from the soil even in hard soil.

  Further, when soil is taken in a deep place such as a cultivating layer, a hole that is large enough to drive the cylindrical body 10 is dug and a long rotating handle 50 (see FIG. 5A) is used. However, other sampling methods may be performed in the same manner as described above. For this reason, compared to the conventional method, which required drilling a large survey hole in advance to insert a hand or scoop when digging, not only collecting the soil can 80, but also significantly reducing the labor for drilling the survey hole can do.
