| 中文摘要: |
| 为实现石灰窑内狭小空间的石灰石二次破碎作业,设计了一种四推杆破碎装置。在完成破碎装置总体结构设计的基础上,通过静力学分析得到了沿镐钎路径的应力分布情况,最大应力值为139 MPa,满足使用要求;通过动力学分析得到了镐钎前六阶的固有频率(第六阶最大值为8 118.7 Hz)及模态振型,并对照仿真数据对破碎装置进行了样机试制,对破碎过程中装置的稳定性进行了校验。结果表明,破碎装置可有效节省窑内二次破碎作业的人力成本且能提高破碎效率和安全性,同时能提升石灰石破碎作业的经济效益。 |

| To realize secondary limestone crushing in the confined space inside a lime kiln, a four-push-rod crushing device is designed. Based on the overall structural design, static analysis was conducted to obtain the stress distribution along the pickaxe path, with a maximum stress of 139 MPa meeting operational requirements; Dynamic analysis yields the first six natural frequencies (maximum value of 8 118.7 Hz for the sixth order) and modal shapes, and prototype testing of the crushing device was conducted compared with simulation data,verifying the stability of the device during the crushing process. The results show that the device can effectively reduce labor costs for secondary crushing operations in the kiln,enhance efficiency and safety, and improve economic benefits in limestone crushing. |
