为了解决湖北—12型简易机耕船杠杆提升农具劳动强度大的问题,于一九七九年设计了棘轮间歇传动式机械悬挂提升机构自动提升农具。四年多来,经耐久性考核试验和在一千多台机耕船上应用,操纵轻便、效果良好、性能稳定可靠。与液压悬挂提升农具比较,其结构简单、制造维修方便、成本低、 In order to solve the problem of large labor intensity of Hubei-12 simple machine-driven lever raising farm implements, a ratchet intermittent mechanical transmission hoisting mechanism was designed in 1979 to automatically raise farm implements. For more than four years, the durability test has been applied and tested on more than 1,000 machine-driven plows. The operation is light, the effect is good, and the performance is stable and reliable. Compared with the hydraulic suspension to enhance farm tools, its simple structure, easy manufacture and maintenance, low cost,
