基于有效种植深度的甘蔗种植机开沟器设计与试验OA

Aiming at the problems of high overall power,uneven depth of trenching,and inability to ensure effective planting depth of the trenching device,a combined trenching device composed of front plow,rotary tiller blade,trenching plow,mudguard,etc.,suitable for sugarcane lateral planting machine was designed as the research object.Discrete ele-ment simulation test analysis of combined trenching device based on EDEM.The experiment showed that the primary and secondary order of factors affecting the power consumption of the furrow plow was trench depth,cutterhead speed,forward speed.The optimal parameter combination was the depth of the furrow 300 mm,the speed of the cutterhead 250 r/min,and the forward speed 0.56 m/s.The field prototype test data showed that the effective depth of sugarcane cultivation reached 302 mm,which was 50.2%higher than the first generation planting prototype.The working resistance of the fur-row plow was reduced by 37.8%,which can satisfy the design requirements of the sugarcane lateral planting machine,ensuring the effective planting depth during precise sowing.
