旋转锹式油茶垦复装置的仿真分析与试验OA

At present,the tillage of the reclamation machines for Camellia forest were shallow and the soil-turnover was not realized.Therefore,a rotary spade reclamation device for Camellia forest was designed according to the principle of the deep-digging of shovel and soil-turnover.The principle of rotary spade reclaiming parts was analyzed,and the dis-crete element model of the interaction between soil and spade was established by means of EDEM software.The stress and strain regularity after the interaction between soil and spade was simulated and analyzed.The motion trajectory of the end point of the spade was analyzed without leakage tillage and secondary tillage,and the rotation speeds of the reclama-tion device with its matching forward speeds were determined.In order to verify the reclamation effect of the reclamation device,the reclamation experiment was carried out in Camellia forest with the plough depth as the index and the rotating speed of the rotating shovel as the factor.Experimental results showed that with the 70° soil inclination,the tillage opera-tion of the reclamation device was normal under the rotating speed of 20～40r/min with the corresponding forward speed of the reclamation device,the average value of the tillage depth was 159～166mm,and the stability coefficient of the tillage depth was 92.72%～94.82%.
