Abstract

This application discloses an automatic filling device for gravity pre-loading columns, relating to the field of automatic filling technology. It includes a main body, a transfer box, and a fixed cylinder. The main body has a discharge port on one side and a pushing mechanism installed inside. The transfer box is fixedly connected to one side of the main body, with an inlet on one side that matches the discharge port. The fixed cylinder is fixedly connected to the outside of the main body and installed above the transfer box. A vibration mechanism is installed on the lower side of the fixed cylinder, and an offset mechanism is installed on the upper side of the transfer box. This device combines spiral propulsion with material agitation to break up agglomerates during transport. It also utilizes a rotating plate to periodically trigger high-frequency vibration of a sliding rod, simultaneously achieving material anti-blocking and compaction. The automatic linkage vibration during filling eliminates gaps through mechanical transmission, resulting in a dual effect that improves compaction. The structural linkage optimizes efficiency and quality.
