Design of a Subsoiler’sauto Reset Shank Using Automotive Leaf Spring
Soil compaction is a severe problem in mechanized crop production. Although measures of avoiding the causes are
recommended, theyhavestill some difficulties in effective implementation. Existing subsoilers used to alleviate soil
compaction are safety bolt types. It is a large cost and time consumption for replacement of the safety bolt when it shears due
to hitting a strong obstacle. In this study, the subsoiler's auto reset shank using automotive leaf spring was to be designed in
order to help ease difficulty of safety bolt replacement. Analysis of the design based on typical subsoiler's configuration was
conducted. Also, new design to meet the practical requirements was proposed.
