| 针对目前贻贝卸苗工序存在自动化程度低、操作繁琐及工人配置不合理等问题，课题组提出了一种螺杆传动式贻贝卸苗设备。借助目前所使用的卸苗设备，课题组从工作环境进行分析，确定卸苗需要的拉力，作为新型设备的设计依据；采用了SolidWorks软件和Simulation模块分别对设备进行结构建模和关键部件的有限元仿真，同时对设备控制系统进行了设计。仿真结果表明：该设备的部件之间装配合理且无干涉存在；卸苗钩和卸苗模具最大应力分别为33.9 MPa和5.89 MPa，均未超出屈服极限206 MPa，最大变形量分别为1.800 mm和0.049 mm，均不影响卸苗作业要求；机架前5阶共振频率段为13~19 Hz，未与卸苗作业振动频率发生重合。设计的贻贝卸苗设备安全可靠,可长时间运行。 |

| Aiming at the problems of low automation, cumbersome operation and unreasonable configuration of workers in the current mussel breeding rope removal process, a screw drive type mussel breeding rope removal equipment was designed.With the aid of the breeding rope removal equipment currently used, the work environment was analyzed to determine the pulling force required for breeding rope removal, as the basis for the design of new equipment.SolidWorks software and Simulation module were used to carry out structural modeling and finite element simulation of key components of the equipment, respectively, and the equipment control system was designed.The simulation results show that the components of the equipment are reasonably assembled and with no interference; the maximum stress of the breeding rope removal hook and the mold are 33.9 MPa and 5.89 MPa respectively, neither of which exceeded the yield limit of 206 MPa, and the maximum deformation is 1.800 mm and 0.049 mm, which does not affect the requirements for operation of breeding rope removal; the first 5th order resonance frequency section of the frame is 13 19 Hz, which does not coincide with the vibration frequency of breeding rope removal process. The designed mussel breeding rope removal equipment is safe, reliable and can run for a long time. |
