Designed for underground mine car transportation, this machine is capable of taking material from 1-ton and 1.5-ton mine cars. It features a screw gathering device with mixing functionality and utilizes a bucket elevator for material pickup. The maximum pickup capacity is 7 cubic meters per hour, and the pickup rate can be automatically adjusted to match the demand of the shotcreting robot. The self-loading shotcreting machine can automatically take material from mine cars, perform shotcreting, support upper computer monitoring, voice broadcast, line-of-sight remote control, and automatically adjust the material feed rate on demand. It works in conjunction with a self-developed shotcreting robot to form a practical intelligent shotcreting operation system, achieving intelligent shotcreting operations.
