针对南方稻田区域稻烟轮作过程中,由于土壤含水率高导致的培土器抛土、输送土能力差,行驶装置驱动易打滑下陷,烟叶生产过程中机械化培土环节与农艺要求不匹配等问题,提出了采用履带底盘螺旋培土机的解决方案,设计了履带底盘螺旋培土机的行驶机构、变速器及螺旋刀盘培土器等基本结构。通过建立螺旋式培土器的运动学与动力学数学模型和对影响螺旋输土的关键指标进行正交试验研究,试验结果表明,当螺旋刀盘半径为130 mm,螺距为110 mm,刀盘入土深度为30 mm,螺旋刀盘转速为260 r/min时,螺旋式培土刀盘输土量符合设计要求。样机田间试验表明,通过合理选择螺旋培土器的基本参数,螺旋培土器能实现烟田清沟...

In order to solve the unmatched problems between mechanized ridging and agronomic requirement in the process of tobacco production,this paper suggested to adopt screw-type banking machine with track chassis,and designed a track chassis drive system with transmission and screw cutter plate and screw-type banking machine.The kinematics and dynamics mathematical model of the screw mechanism was established and the key indicators affecting the quantity of screwed soil by orthogonal experiment was studied.The experimental results showed that when the screw cutter radius was 130 mm,pitch was 110 mm,...
