 Details of each part will be described below with reference to the drawings.

As shown in FIGS. 4 to 8, the packer 40 includes a pair of left and right lifting column columns 41, 41 that symmetrically oppose the center line of the silo, a receiving port 48 and a clamp 47, respectively, in a hydraulic cylinder (or air cylinder) 46a ,. It is composed of a mounting column 45 for pin-supporting the upper flat plate 46 supported by 46b. The hoisting column 41 is a pin fulcrum for the hook 44 that suspends the hanger 100b of the flexible container bag.
It is tiltable around a hydraulic cylinder 43 around 44, and is erected so as to be tiltable near the floor of the carriage 4 via a hydraulic cylinder 42 by a hinge. The chain double-dashed line in FIG. 5 shows a state in which the height of the lifting hand 100b is lowered due to the tilting of the lifting hand column 41 as the bulk material is filled.

On the other hand, the mounting column 45 constitutes a parallelogram link in this embodiment, and the upper flat plate 46 is formed by the two pin fulcrums at the upper end.
In addition to being pin-joined to the electric bogie 4 at the lower end, it is also pin-jointed to the floor near the floor of the electric carriage 4 so that it can be tilted by the operation of the hydraulic cylinder 45a. Then, the receiving port 48, the upper receiving port 48a and the lower bag mouth mounting port 48c are vertically connected via an elastic bellows tube 48b in the middle, and the outer periphery of the bag port mounting port 48c is
A pair of clamps 47, into which an elastic body 47a such as rubber is fitted, and which are divided into two substantially semicircles, are moved forward and backward by the air cylinder 47b, and the intake 100a of the flexible container bag 100 is detachably attached to the bag mouth attachment port 48c.
