Feeding device

A feeding device is provided. The feeding device comprises a feeding box, a discharging assembly and a weighing assembly. A feeding channel is arranged in the feeding box to contain materials, and the feeding channel is communicated with the outside of the feeding box through the discharging port. The discharging assembly can move along the path of the feeding channel so that the materials can leave the feeding channel through the discharging port. The weighing assembly is arranged on the feeding channel to weigh materials. Therefore, the materials with certain mass can be automatically fed into the mixing machine, and the feeding efficiency is improved. In addition, an operator can keep a certain distance from the mixing machine, so that the operator is prevented from being exposed to a severe working environment. 提供了一种投料装置。该投料装置包括投料箱、出料组件和称量组件。投料箱内部设置有投料通路以容纳物料，投料通路通过出料口与投料箱的外部连通。出料组件能够沿投料通路的路径移动使物料经由出料口离开投料通路。称量组件设置于投料通路以称量物料。这样，物料能够以一定的质量自动投入混合机，投料的效率得到了提升。此外，操作人员能够与混合机保持一定的距离，防止操作人员暴露于恶劣的工作环境。
