ダ（８）伸長方向に切換るようになっている。An auxiliary flow path (18) is branched from the main flow path (17) between the first cylinder (8) and the switching valve (15) and connected to the ram cylinder (13). A check push switching valve (19) is installed, and under normal conditions, the main flow path (17) is installed.
) This is a check valve (20) that restricts the flow to the side, and is provided so that it is in an open state when switched. Figure 7 is an electric circuit diagram for upward rotation of the bunker (3). By switching the switch (21) to one side (upper side in Figure 7), the solenoid SO[3 is energized and the switching valve (15) is turned to the upper side. 1 cylinder (8) is designed to switch in the extension direction.

し、その状態より第１シリンダ（８）！縮小させて第４
図の如く塵芥を容器（１）側に押込む。The present invention has the above-mentioned structure. Next, the operation will be explained. When pushing the garbage into the container (1), the second cylinder (9) is charged from the input port (4) of the bunker (3). From the state shown in the figure, the first cylinder (8) is extended and contracted to compress the debris to some extent on the pushing plate (7) as shown in Fig. 3, and from that state the first cylinder (8)! Shrink it to the 4th
Push the garbage into the container (1) as shown.
塵芥の押込みが終了すると第２シリンダ（９）を伸長さ
せることにより、第２図の元の状態に戻る。When the pushing of the garbage is completed, the second cylinder (9) is expanded to return to the original state shown in FIG. 2.
その際、ラムシリンダ（１３）−も油が供給され斧がバ
ンカ（３）がロック装置（６）にてロックされているの
でラムシリンダ（１３）は伸長ずやことはない。At this time, the ram cylinder (13) is also supplied with oil and the ax bunker (3) is locked by the locking device (6), so the ram cylinder (13) does not extend.
次に、バンカを上方回動ざぜて清掃作業等を行う場合に
は、まずロック装置（９）を解除した後スイッチ（２１

リンダ（８）とともにラムシリンダ（１３）を伸長させ
る。Next, when performing cleaning work by rotating the bunker upward, first release the locking device (9), and then release the switch (21).
) to one side, the switching valve (15) is switched, and the ram cylinder (13) is extended together with the first cylinder (8).
そして所定の位置でスイッチ（２１）をｌ；７Ｊ換れば
切換弁（１５）はロック位置になりバンカ（３）を所定
の位置に止めることができる。If the switch (21) is turned to 1;7J at a predetermined position, the switching valve (15) becomes the lock position and the bunker (3) can be stopped at the predetermined position.
その際、チェック押付切換弁（１９）が通常ｌへのまま
なのでラムシリンダ（１３）はバンカ（３）の、ト昇に
伴って伸長づるが縮小は規制されバンカ（３）を確実に
支持するようになっている。At this time, since the check press switching valve (19) normally remains at L, the ram cylinder (13) expands as the bunker (3) rises, but its contraction is restricted and it reliably supports the bunker (3). It looks like this.

Switch the first cylinder (E3) and ram cylinder (1
3) is reduced by the bunker (3)'s own weight, etc., and finally the bunker (3) is locked by the locking device (6).

に行うことができる。(f) Effects of the invention As described above, the present invention provides a ram cylinder between a container and a bunker, connects an auxiliary flow path branched from the main flow path of the cylinder forming a part of the pushing device, and connects the auxiliary flow path to the cylinder. A switching valve with a check valve is installed in the bunker, so even if the bunker attempts to descend due to oil leakage in the pushing device, it will be reliably supported by the ram cylinder and can be supported in any position, allowing cleaning work etc. to be carried out safely. I can do it.
