Since the same bagging operation can be performed, it can be used when a small amount of sandbag is produced or in a small work place. Furthermore, sales according to the scale of construction, construction sites, construction machines, etc., such as sales of the divided support frames 3 alone or sales of two or four, are possible.
[0033]
Next, a sandbag manufacturing apparatus according to another embodiment will be described with reference to FIG. The support frame 3 of this manufacturing apparatus is manufactured so that a plurality of support frames 3 can be connected and assembled by the same configuration of the connecting means as in the above-described embodiment. An appropriate number of partition frames 1 having a small diameter and a large diameter on the upper side are formed by the same arrangement as that of the above embodiment.
And the opening frame board 2a which has many input ports 11a in the upper part of the support frame 3 is formed in the same magnitude | size as the support frame 3, and is installed so that attachment or detachment is possible. The insertion port 11a is opposed to the central portion of each partition frame 1 and forms a bag locking opening frame 2 that rises upward in the periphery thereof.
[0034]
Moreover, the earth receiving cover 10 which has the insertion port 11 which positions and fixes the sandbag W similarly to the said embodiment is installed in the upper part of the said opening frame board 2a so that attachment or detachment is possible.
According to the support frame 3, the earthenware cover is manufactured by placing the earth receiving cover 10 from above in a state where the opening part of the earthen bag W inserted in the partition frame 1 is locked to the opening frame 2 of the opening frame plate 2 a. By doing so, the opening is fixed, and the soil 23 is filled and supplied from the charging port 11 into the soil bag W. Next, after removing the earth receiving cover 10 and the opening frame 2a, the string W1 is tied and the opening is closed. Then, as described above, the sandbags W can be lifted using the lifting device 50 and taken out at once.
