With the expansion of industrial production scale and the improvement of automation level, traditional fixed heavy-duty plate feeders can no longer meet the needs of frequent adjustment of working positions in scenes such as open-pit mining and large-scale material yard transportation, and self-moving heavy-duty plate feeders have come into being. This type of equipment can move autonomously to adapt to changes in the material stacking position through the integrated walking mechanism, which greatly improves the flexibility and scope of operations and becomes the core equipment for material transportation under high load and harsh working conditions. However, in actual applications, the existing self-moving heavy-duty plate feeder cannot achieve coordinated control of feeding operations and walking movements. It is usually necessary to stop walking before stable feeding can be carried out, or during the walking process, the mismatch between feeding parameters and walking speed leads to uneven material transportation, seriously affecting the continuity and efficiency of subsequent processes.
