Material blocking and buffering device of feeding system of ore sorting machine

A material blocking buffer device of a feeding system of an ore sorting machine comprises a vibrating screen, a material blocking rubber sheet and a detection belt, the detection belt is arranged in a detection bin, a slide carriage is fixed to an inlet of the detection belt, the end of the slide carriage obliquely extends to an outlet of the vibrating screen, the material blocking rubber sheet is arranged over the slide carriage, and the detection belt is arranged in the detection bin. The top of the material blocking rubber sheet is fixed on an upper bin plate of the detection bin through a connecting piece, the bottom of the material blocking rubber sheet naturally droops, and a gap for ore particles to pass through is formed between the bottom of the material blocking rubber sheet and the slide carriage. The feeding performance of the feeding system is improved, and the detection precision and the separation precision are improved. 一种矿石分选机给料系统挡料缓冲装置，包括振动筛、挡料胶皮和检测皮带，所述检测皮带设置在检测仓内，所述检测皮带的进口处固定有溜板，所述溜板的端部倾斜延
