摘要
【目的】研制一种自激振动深松机.这种深松机在工作过程中,由于非线性土壤耕作阻力作用到振动深松铲上,压迫弹簧往复振动,从而减小机具的牵引阻力,降低功耗.【方法】通过性能试验和查询已经成熟的技术文献,设计深松铲的结构并优化.为了评估样机性能,进行田间试验.【结果】田间试验表明,从无弹簧到Ⅱ号弹簧,深松机可减阻17.76%,深松深度为386.61~406.23mm,稳定性系数为93.30%左右,土壤蓬松度为24.18%~28.65%,土壤扰动系数为53.55%~57.06%,深松效果良好.【结论】本自激振动深松机能够有效减小牵引阻力,降低机具功耗,各项工作参数达到评定指标.
【Objective】To develop a self-excited vibration subsoiler.When working,its springs on vibrating attachments have been driven reciprocating vibration by changing of soil tillage resistance,and so the tractive resistance and energy consumption of the vibration subsoiler is reduced.【Method】The model of the subsoiler was designed and optimized by using some well-established technologies and reliable literature.To assemble every component of the vibration subsoiler and do interference check,finally finishing the structure optimization.In order to evaluate the performance of the prototype,field experiments were carried out.【Result】The tillage resistance has been decreased by 17.6%,the subsoiling depth is 381.6~406.23 mm,the stability coefficient is about 93.30%,the soil bulkiness is 24.18%~28.65% and the soil disturbance coefficient is 53.55%~57.06%.Subsoiling effect is better.【Conclusion】The self-excited vibration subsoiler effectively reduce the tractive resistance and its energy consumption.The working parameters of the test results are good enough to meet the design requirements.
