Since the impact sample is relatively small in size and relatively large in quantity, the operator needs to perform frequent feeding operations, which not only affects work efficiency but also poses certain safety hazards. In view of this, some steel enterprises have developed automatic sample feeding devices for impact samples. Although these devices have relatively high automation and can improve work efficiency, they have certain limitations, mainly because the design structure of these devices is relatively complex and the manufacturing cost is relatively high. Therefore, it is necessary to develop a relatively economical impact sample feeding device.
