Experimental Study of Potato Digger Based on Vibration Mechanism
To solve the potato mechanized harvest problem in southwest, part of the northern and the central plains re-gion, combined with cropping patterns and agronomic requirements of domestic, an experimental study was carried out on the single-line vibrating potato digger.Forward speed, digging depth and vibration frequency were the test factors.Trac-tion resistance was the evaluation index.The results of the orthogonal test show that when the digging depth is 139 ~155mm, the vibration frequency is 3~14Hz and the forward speed is 2.5~3.0km/h, the traction resistance reaches a minimum.Under this condition a verification test was carried out and the results show that the average traction resistance is 956.6N, decreased 36.2%compared to the operation with no vibration.While the obvious rate and the injury rate in harvest test were 97.2%and 3.52% respectively.They all comply with the relevant standards.This paper provided a solution for the potato mechanized harvest in small plots and complicated condition arable land and provided a reference for the further development of potato digger.
