It can be returned upward again by (122).

The expandable bin 7 of FIG. 59 is also shown in that the bin sections 32A (not shown), 32B, 32C, 32D (not shown) can each have a filler plate 118. As shown in 60, when the lifting plate 88 and the height adjusting plate 86 are moved downward, the gap between the side plates 54 of the

barrel sections

32A, 32B, 32C, and 32D and the height adjusting plate 86 becomes a gap filling plate. It can be largely filled by (118). That is, when the lifting plate 88 and the height adjustment plate 86 are moved downward, the gap between the

barrel sections

32A, 32B, 32C, 32D and the height adjustment plate 86 is closed by the gap filling plates 118. It can be filled.

The barrel section 32A included in the expandable barrel 7 of FIG. 61 may have one or more lower height fixing hole supports 119 as shown in FIGS. 56 (A) and 56 (B). , a lower height fixing hole 120 may be formed in the lower height fixing hole support portion 119.

The lower height fixing hole support portion 119 is formed on the lower plate 52 of the barrel section 32A, but this is illustrative and not limited thereto.

The expandable barrel 7 of FIG. 61, although not shown in the drawing, has

height fixing devices

29A and 29B including height fixing bars 70 installed on the lifting plate 28 as shown in FIG. 57, or As shown in 59,

height fixing devices

29A and 29B including height fixing bars 70 are installed on the height control plate 86.

Figure 61 shows a state in which the lifting plate 28 or the height adjusting plate 86 is moved upward, the expandable barrel 7 is contracted, and the height fixing latch installed on the lifting plate 28 or the height adjusting plate 86 is shown. As (70) are respectively inserted into the upper height fixing holes 34, the height of the lifting plate 28 or the height adjusting plate 86 is fixed.

62 shows a diagram in which the elevating plate 28 is moved downward or the elevating plate 28 and the height adjustment plate 86 are moved downward in the expandable barrel 7 of FIG. 61, and the expandable barrel 7 is expanded. In addition, the height fixing bolts 70 installed on the lifting plate 28 or the height adjusting plate 86 are respectively inserted into the lower height fixing holes 120, so that the height of the lifting plate 28 or the height adjusting plate 86 can be adjusted. It indicates a fixed state.

Instead of forming the lower height fixing hole 120 in the lower height fixing hole support portion 119, although not shown in the drawing, a groove or a stopper is formed, and the height fixing latch 70 is inserted into the groove, or The height of the lifting plate 28 or the height adjustment plate 86 can be fixed by being caught on the stopper.
