摘　　要：为满足硬质土壤或板结土壤的深松作业要求,一次性完成土地的深松和平整,设计了一种1SZL-300型振动深松整地联合作业机。开展了深松部件设计和深松铲入土过程受力分析,进行了基于EDEM的深松铲正交试验。同时,采用三因素三水平的Box-Behnken试验设计原理进行仿真组合试验,仿真试验,结果显示:当入土角度为31.42°、入土深度为392.59 mm、作业速度7.02 m/s时,模型预测的土壤蓬松度为44.903%,土壤扰动系数为57.845%。最后,针对样机进行了田间试验,结果表明:深松深度382 mm,深松耕深稳定性系数96.8%,地表10 cm内,碎土率达62.8%,纯工作小时生产率为2.2 hm^(2)/h,作业效果满足设计要求。In order to meet the requirements of deep loosening operation of hard soil or compact soil and realize the deep loosening and land leveling at one time,this paper designed a 1SZL-300 vibrating joint machine for deep loosening and soil leveling.This paper carried out the subsoil component design and the force analysis of the subsoil shovel into the soil,studied the EDEM-based orthogonal test of the subsoil shovel,and used the three-factor and three-level Box-Behnken test design principle to carry out the simulation combination test.The results of simulation experiment indicates that when the soil penetration angle is 31.42°,the depth of deep loosening is 392.59 mm,and the working speed is 7.02 m/s,the predicted soil looseness is 45.42%,and soil disturbance coefficient is 57.60%.Field experiment shows that the subsoil depth of the prototype is 382 mm,the stability coefficient of subsoil depth is 96.8%,the soil crushing rate(within 10 cm of the surface)is 62.8%,and the productivity of net time is 2.2 hm^(2)/h.
