によっても行うことができるようになっている。Figure 1 shows the entire pneumatic unloader, in which cargo (2) in a bulk carrier (1) is transported through a suction nozzle (3).
It is sucked in together with air and flows into a separator (7) via a vertical telescoping pipe (4), a bend pipe (5), and a horizontal telescoping pipe (6). The transported material and air flowing into the separator (7) are separated, and the transported material is transferred to the rotary feeder (8).
The air is discharged onto the in-flight conveyor (9) and supplied to the quay conveyor 00 or 靜αD, while the air passes through the air pipe (2) and is sucked into the suction blower a3. There is. Further, the vertical telescoping pipe (4) can be extended and contracted by a vertical telescoping drive device α→ to raise and lower the position of the suction nozzle (3), and the horizontal telescoping pipe (6) is also horizontally telescoping driven. The device 00 can expand and contract to move the position of the suction nozzle (3) in the horizontal direction. Further, a levitation drive device (to) for undulating the entire suction piping system is provided so that the suction nozzle (3) can be moved up and down by the operation of the levitation drive device (to).
上記したニューマチックアンローダにおいて、従来の吸
引ノズルは第３図に示すように構成されている。In the above-mentioned pneumatic unloader, the conventional suction nozzle is constructed as shown in FIG.

せることにより前記内外筒差（−）を増減することがで
きるようにしている。That is, the conventional suction nozzle (3) is made up of an outer cylinder (,) and an inner cylinder (6), and sucks the food and primary air from the primary air and food suction port (1) at the bottom. , secondary air is sucked in from the upper secondary air suction port (d). At this time, the secondary air passes between the inner and outer cylinders (α) and (b), joins the primary air and the sprinkler at the lower part, and is sucked. In addition, in order to adjust the difference (secondary air suction gap) (e) between the inner and outer cylinders (α) and (b), the upper parts of the inner and outer cylinders (,) (6) are screwed together via a screw Cf). By rotating the outer cylinder (a), the difference (-) between the inner and outer cylinders can be increased or decreased.
しかし上記従来装置においては以下に示すような問題点
を有していた。However, the conventional device described above had the following problems.
吸引ノズル（３）の内外筒差（ｇ）の調整は前記従来装

引作業を一時中断すると荷役効率が悪くなるという理由
から、一度内外筒差（１）を設定したら、吸引作業が完
了するまで、そのままの状態で吸引作業を行っているの
が現状である。Adjustment of the difference (g) between the inner and outer cylinders of the suction nozzle (3) can also be performed with the conventional device, but in order to adjust the difference (1) between the inner and outer cylinders during suction, the bulk carrier shown in FIG. (
The worker must either enter the hatch in step 1) or temporarily suspend the suction work and move the suction nozzle (3) above the deck. However, in the former case, it is very difficult for the worker to approach the suction nozzle (3) by walking on the materials being thrown, and in the latter case, the cargo handling efficiency will deteriorate if the suction operation is temporarily interrupted. At present, once the difference (1) between the inner and outer cylinders is set, the suction operation is performed in that state until the suction operation is completed.
ところが、この内外筒差（＃）は吸引能力に大きな影響
を与える要素であり、内外筒差（＃）を大きくすれば吸
引能力と吸引圧力は小さくなり、逆に内外筒差（−）を
小さくすれば吸引能力と吸引Ｗ力は大きくなる傾向を示
す。However, this difference (#) between the inner and outer cylinders is a factor that greatly affects the suction capacity, and if the difference (#) between the inner and outer cylinders is increased, the suction capacity and suction pressure are reduced, and conversely, the difference (-) between the inner and outer cylinders is decreased. Then, the suction capacity and suction W force tend to increase.

で運転されるので荷役効率が悪い問題がある。In this regard, when performing suction work from the start to the end with the difference (1) between the inner and outer cylinders set to a certain dimension as in the latter case, the length of the suction piping system is the longest. The difference (1) between the inner and outer cylinders is set so that the maximum operating (permissible) pressure of the suction blower α1 (see Figure 1) is achieved.
The difference between the inner and outer cylinders (1) to achieve the maximum working pressure that the port has.
This is because if you set , the maximum working pressure of the suction blower will be exceeded when the length of the suction piping system becomes the longest). Therefore, as mentioned above, if the length of the suction piping system is shortened and the difference between the inner and outer cylinders (1) is left unchanged, the suction pressure of the suction blower (to) will not be used effectively. Moreover, since it is operated with low suction capacity, there is a problem of poor cargo handling efficiency.
