に設けることが一般であるが、このようにした場合には
、運搬車からトラック等に収穫物を積替えるに際し、そ
の収穫物等を低位置から高位置へ持ち上げる必要がある
ため、作業に労力を要し、作業能率を向上し得ないもの
であった。Conventionally, in this type of power transport vehicle, the loading platform was generally installed as low as possible in order to facilitate the loading of crops, etc.; When transferring harvested products to a truck or the like, it is necessary to lift the harvested products from a low position to a high position, which requires labor and makes it impossible to improve work efficiency.
本案はかかる欠点に鑑みなされたものであって、積替え
作業時の持ち上げ作業を必要としない昇降自在な荷台を
提供するばかりでなく、昇降機能の他にダンプ機能をも

持させることで、リンク４ａ 、４ｂ間の間隔を固定さ
せて開きを防止させ、パンタグラフ機構４を折畳み状態
に保持させるものである。One end is rotatably supported by the 9 pivot pins on the link upper end 4b', and a groove 14 is formed on the side to removably engage with the 6 pivot pins on the link lower end 4a'. , the distance between the links 4a and 4b is fixed by engaging the six pivot pins when the pantograph mechanism 4 is folded, and then screwing the nut 15 onto the six pivot pins from above and fixing the nut 15. This prevents the pantograph mechanism 4 from opening and maintains the pantograph mechanism 4 in its folded state.
又この折畳み状態を保持させる他の手段としては、前方
のリンク上端４ ｂ ／／を荷台３に固持させるように
したものでもよい。Further, as another means for maintaining this folded state, the upper end of the front link 4b may be fixed to the loading platform 3.
尚図中１６で示すものは、案内枠８の摺動溝であり、間
溝１６に沿って案内枠８を摺動させることで、案内ロー
ラ７との嵌合を着脱させ、これにより、リンク下端４ａ
“の支持を着脱自在にさせるものである。The reference numeral 16 in the figure is a sliding groove of the guide frame 8. By sliding the guide frame 8 along the groove 16, the guide roller 7 is fitted into and removed from the link. Lower end 4a
``The support is removable.
又１７は開き防止金具１３を、その不使用時において荷
台３に止め付けておく収納金具である。Further, reference numeral 17 denotes a storage fitting for fixing the opening prevention fitting 13 to the loading platform 3 when the opening prevention fitting 13 is not in use.
従って、案内枠８にリンク下端４ａ“の案内ローラ１を
嵌合させるとともに、開き防止金具１３を収納金具１７
に止め付けた状態で油圧シリンダー１２を作動してピス
トンロッド１２“を進出させると、各案内ローラ７．１
０をそれぞれ案内枠８．１１に沿って移動させながらリ
ンク４ａ。Therefore, the guide roller 1 at the lower end 4a'' of the link is fitted into the guide frame 8, and the opening prevention fitting 13 is fitted into the storage fitting 17.
When the hydraulic cylinder 12 is operated to advance the piston rod 12'' with the piston rod 12'' fixed to the
0 along the guide frames 8.11, respectively, the link 4a.
４ａ、４ｂ、４ｂが開いてパンタグラフ機構４は伸長し
、これに伴って荷台３は第２図に示すように機台５と平
行に上昇するものである。4a, 4b, and 4b are opened, the pantograph mechanism 4 is extended, and the loading platform 3 is raised parallel to the machine platform 5 as shown in FIG.
そしてこの状態を保持して荷台３の収穫物をトラック等
に積替、ｔ＊のち、ピストンロッド１２〃を退入させる

これに支持された荷台３を第３図に示すように後方にダ
ンプさせるものである。Next, the guide frame 8 is slid to ensure that the link lower end 4a'' is engaged with the guide roller 7, and the opening prevention fitting 1
When the hydraulic cylinder 12 is operated with the groove 14 of No. 3 engaged with the pivot pin 6 and held firmly, the pantograph mechanism 41fi is folded into the folded housing as the Vinton rod 12'' is extended. Tilts backwards around pivot point 6,
The loading platform 3 supported by this is dumped rearward as shown in FIG.
そしてこのダンプ状態において荷台３の収穫物を落下さ
せたのち、ピストンロッド１２“を退入させると、上述
とは逆にパンタグラフ機構４が倒伏し、荷台３は原水平
位置に復帰するものである。In this dump state, when the piston rod 12'' is retracted after dropping the crops on the loading platform 3, the pantograph mechanism 4 falls down, contrary to the above, and the loading platform 3 returns to its original horizontal position. .
本案は上述のように構成したので、荷台を昇降させるだ
けでなく、ダンプをもさせ得るので、積載物の積替え、
或いは荷下しが容易になり、その作業に要する労力を軽
減させて作業能率を向上させることができるという効果
がある。Since this project is configured as described above, it is possible not only to raise and lower the loading platform, but also to dump it, so it is possible to transfer the loaded material,
Alternatively, there is an effect that unloading becomes easier, the labor required for the work is reduced, and work efficiency can be improved.
又昇降動作とダンプ動作とを共通の油圧シリンダーによ
