    摘要： A combination weighing and mixing apparatus for fertilizer or the like comprising a skip loader normally freely supported on a weigh scale and which is pivotal about one of its upper ends by a hydraulic cylinder means to facilitate the dumping of the material therefrom into a mixing drum after the material has been weighed. The mixing drum is of the type used in the cement-mixing industry and is designed to mix the material deposited therein while revolving in one direction and to discharge the material therefrom while revolving in the opposite direction. The apparatus also includes means for automatically freeing the skip loader from the cylinder means and the skip loader support means while the skip loader is supported on the weigh scale. The cylinder means includes means thereon to insure that the skip loader will be gently placed on the weigh scale after the material has been dumped therefrom.
