    摘要:

    針對(duì)傳統(tǒng)果園種植模式迫切需要行間高通過(guò)性植保動(dòng)力機(jī)械的現(xiàn)狀，設(shè)計(jì)了低矮型自走式果園噴霧機(jī)動(dòng)力底盤,。通過(guò)理論計(jì)算與虛擬樣機(jī)分析,，設(shè)計(jì)了多動(dòng)力輸出分動(dòng)裝置，實(shí)現(xiàn)各工作部件獨(dú)立運(yùn)轉(zhuǎn),；行走變速箱與高低速擋位配合操作,，實(shí)現(xiàn)（3+1）×2個(gè)擋位，并可根據(jù)路面狀況進(jìn)行兩驅(qū)與四驅(qū)自由切換,；整機(jī)行間最低通過(guò)高度1600mm,；前輪越障高度隨藥量變化緩慢，由87mm下降到70mm,，后輪越障高度與噴霧機(jī)重心無(wú)關(guān),；最小轉(zhuǎn)彎半徑2000mm左右?；贑reo的仿真結(jié)果顯示機(jī)具穩(wěn)定性好,，變速范圍為1.5～16km/h，藥箱藥液量的變化對(duì)整機(jī)重心變化及其坡道行駛穩(wěn)定特性影響較小,。

    Abstract:

    A low self-propelled sprayer for conventional orchard was developed in order to solve the plant protection mechanization. The power distribution unit was designed by theoretical analysis and virtual prototype to realize all working parts running independently. Eight shifts were designed by main and assistant gear-box. The sprayer could switch two-wheel drive to four-wheel drive according to running condition. Its minimum trafficable height was 1600mm. In the dosage range of 0~400L, the front wheels crossed obstacles reduced from the 87mm to the 70mm, and rear wheel obstacles height was independent of dosage. The minimum turning radius was about 2000mm. The simulation result by Creo Parametric 2.0 showed the sprayer worked steadily, and the velocity was between 1.5 to 16km/h. The effects of pesticide volume on centre of gravity and stability were little.
