    摘要:

    設(shè)計(jì)了一種適合作物株間作業(yè)的八爪式機(jī)械除草裝置，采用Pro/E進(jìn)行了虛擬樣機(jī)設(shè)計(jì)，建立了除草裝置的裝配模型，利用ADAMS軟件對(duì)該裝置進(jìn)行運(yùn)動(dòng)學(xué)仿真，得出在不同速比下的除草鏟齒運(yùn)動(dòng)軌跡，通過計(jì)算得到除草鏟齒與土壤接觸部分的面積，并對(duì)每個(gè)鏟齒的覆蓋區(qū)域以及相鄰鏟齒覆蓋的重合區(qū)域進(jìn)行分析，確定的合理速比為λ=0.754，優(yōu)化了裝置的結(jié)構(gòu)和運(yùn)動(dòng)參數(shù)。

    Abstract:

    An intra-row mechanical weeding device was designed. The device is one part of intelligent weeding machine. It has eight hoes that could turn in or turn out of intra-row area in the intelligent control system to eliminate the intra-row weeds. A 3-D parametric model of intra-row mechanical weeding device was built up with Pro/E, and was input ADAMS. The device was simulated on kinematics by ADAMS to get the track of each hoe. By analyzing the tracks, the area for each hoe with the superposition of adjacent hoe were figure out. Based on analysis result, the optimal proportion of rotation speed and forward speed was obtained (λ=0.754). Simulation proved that the device could satisfy the need of intra-row weeding.
