A ton bag moving trough 1 and a safety guardrail 4 are fixedly installed on the upper end surface of the steel structure frame 24, a bag breaking device 17 is fixedly installed on the lower end surface of the protective cover 2, a dust removal pipe 3 is fixedly installed on one side of the protective cover 2, the dust removal pipe 3 is fixedly connected to the vibrating screening machine 5, a plurality of hopper scales 18 are arranged on the lower end surface of the vibrating screening machine 5, a belt conveyor 9 is also fixedly installed on the lower side of the steel structure frame 24, the belt conveyor 9 is arranged below the plurality of hopper scales 18, a standing plate 6 is also fixedly installed inside the steel structure frame 24, a ton bag pushing cart 7 is also arranged on the bottom side of the steel structure frame 24, and a safety escalator 10 is also fixedly installed on one side of the steel structure frame 24.

[0021] In this embodiment, the connection between the steel structure frame 24 and the ton bag moving trough 1 and the safety guardrail 4 is welded. The main purpose of this arrangement is to prevent casualties caused by workers falling or accidentally stepping into the bag breaking device 17 when working on it. The protective cover 2 and the bag breaking device 17 are connected by bolts. Its main function is to be able to quickly and easily break the ton bag 8 during work. The connection between the protective cover 2 and the dust removal pipe 3 is welded. The connection between the dust removal pipe 3 and the vibration screening machine 5 is a pipe connection. The main function of the dust removal pipe 3 is to absorb the smoke generated during screening inside the vibration screening machine 5. Two hopper scales 18 are installed on the lower end face of the vibration screening machine 5. The main function of the hopper scale 18 is to measure alloy steel particles that meet the specifications. The main function of the belt conveyor 9 installed on the lower side of the hopper scale 18 is to reload the screened materials into the ton bag 8. The main function of the standing plate 6 installed inside the steel structure frame 24 is to facilitate the observation of the conditions inside the vibration screening machine 5.
