FIG. 7 is a partially enlarged longitudinal sectional view showing a state in which the inner tube is being inserted into the outer tube.
FIG. 3 is an enlarged plan view of an outer tube. [0007] As shown in FIGS.
Is a piercing portion 2 having a closed end and a sharpened tip, a pipe-shaped outer tube 3 having a base end open on the opposite side to the piercing portion 2, and a tightly inserted state inside the outer tube 3 from the distal end. The inner tube 5 is made insertable, and is rotatable relative to the outer tube 3 around each center line in the inserted state. The inner tube 5 is provided with a grip 4 at its base end. In the outer tube 3, five outer tube holes 6 are arranged in a straight line at a fixed interval between the vicinity of the piercing portion 2 and the base end, while the inner tube 5 is in the inserted state. A case portion 8 having five inner tube holes 7 is provided on a side surface corresponding to each of the outer tube holes 6. As shown in FIGS. 6 and 7, at the base end (upper end in FIG. 1) of the outer tube 3, a rotation guide groove 9 is formed in an inner periphery in a ring shape. A connector 11 having an insertion guide groove 10 extending to an end opposite to the pipe 3
Are fitted and fixed. Also, in the rotation guide groove 9,
The first pin stopper 9a is located in the vicinity of the insertion guide groove 10, and the first pin stopper 9a is
The second pin stopper 9b is protruded at a position rotated by 80 degrees. On the other hand, in the vicinity of the grip 4 of the inner tube 5, there are provided a ring-shaped stopper 12 and a guide projection 13 which can be movably fitted in the rotation guide groove 9 via the insertion guide groove 10. Then, the inner tube 5 is inserted into the outer tube 3, and when the connecting ring 11 and the ring-shaped stopper 12 approach each other, the guide projection 13 of the inner tube 5 is connected to the connecting ring 1 of the outer tube 3.
When inserted into the rotation guide groove 9 through the first insertion guide groove 10, the double-tube type spine 1 is configured (see FIG. 1). Subsequently, the inner pipe 5 is moved relative to the outer pipe 3 by approximately 1
Rotationally displaces 80 degrees counterclockwise (in FIG. 7), the second
The guide projection 13 hits the pin stopper 9b and stops. The second pin stopper 9b has a guide projection 1
3 is a state in which the outer tube hole 6 and the inner tube hole 7 overlap and the case 8 is opened (see FIG. 3).
The state in which the inner pipe 5 is rotationally displaced clockwise (as shown in FIG. 7) with respect to the outer pipe 3 and stops against the first pin stopper 9a is the outer pipe hole. 6 and each inner tube hole 7 does not overlap, and the case 8 is closed (see FIGS. 4 and 5). [0010] As shown in FIG.
Is formed by partitioning the inner space of the inner tube 5 with partition walls 14 in the form of bamboo nodes corresponding to both axial end portions of each inner tube hole 7 to form the same number as the outer tube holes 6. Grains and the like surely flow into and out of each case portion 8 from each inner tube hole portion 7 corresponding to the outer tube hole portion 6. Next, a method of using the double-tube type grain stick 1 will be described. The outer tube 3 and the inner tube 5 are relatively rotated and displaced on their center lines, and the second pin stopper 9b is brought into contact with the guide projection 13 and stopped (the case portion 8 shown in FIGS. 4 and 5 is closed). State), for example, after inserting the piercing portion 2 at the tip from the upper part of the cereal piled up on the ship to the floor of the hold, the outer pipe 3 and the inner pipe 5 are relatively moved in the opposite direction to the above. By rotating and displacing, the first pin stopper 9a is brought into a state where the guide projection 13 comes into contact with the first pin stopper 9a and stops (the state where the case portion 8 shown in FIG. 2 is opened), and the surrounding grains are poured into the case portion 8. Subsequently, the outer pipe 3 and the inner pipe 5 are again rotationally displaced in the opposite direction to the above, and the case section 8 is closed as shown in FIGS. The outer tube hole 6 and the inner tube hole 7 are overlapped, each case 8 is opened, and sample grains are taken out of the case 8 on a sheet or the like. The present invention is not limited to the above-described embodiment.
