    摘要： A charging box for a scrap metal shear is provided with a top opening where a compressed block of scrap metal may be loaded. A first ram is provided to the rear of the scrap metal block so that it may be pushed forward for a short distance in the charging box. A second ram is provided whose rear most position is behind the forward most position of the first ram means. After the first ram is retracted the second ram means is brought into position behind the block of scrap to continue movement of the scrap block into the shear. The two rams are so arranged that while the second ram is feeding a block of scrap metal into the shear a second block may be loaded into the charging box and moved forward by the first ram until the first ram has reached its forward most position where the block of scrap may then be engaged by the second ram when it is returned from feeding the first block of scrap into the shear. The means are provided for elevating the second ram above the block of scrap metal as the second ram is returned to its initial engaging position behind the block of scrap.

    摘要翻译： 用于废金属剪切的充电箱设置有顶部开口，其中可以装载压缩的废金属块。 第一压头设置在废金属块的后部，使得其可以在充电箱中向前推动短距离。 提供了一个第二压头，其最后部位置位于第一压头装置的最前端位置之后。 在第一压头缩回之后，第二压头装置被置于废料块的后面，继续将废料块移动到剪切机中。 两个公柱被布置成使得当第二压头将一块废金属供给到剪切机中时，第二块可以被装载到充电箱中并且被第一压头向前移动，直到第一压头已经到达其最前面的位置， 然后当从第一块废料进料到剪切器中时，废料块可以被第二压头接合。 该装置被设置用于当第二压头返回到废料块后面的初始接合位置时，将第二压头提升到废金属块上方。
