    摘要:

    針對傳統(tǒng)果園種植模式迫切需要行間高通過性植保動力機械的現(xiàn)狀，設計了低矮型自走式果園噴霧機動力底盤,。通過理論計算與虛擬樣機分析,，設計了多動力輸出分動裝置,，實現(xiàn)各工作部件獨立運轉,；行走變速箱與高低速擋位配合操作,，實現(xiàn)（3+1）×2個擋位,，并可根據(jù)路面狀況進行兩驅與四驅自由切換,；整機行間最低通過高度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重心無關,；最小轉彎半徑2000mm左右,。基于Creo的仿真結果顯示機具穩(wěn)定性好,，變速范圍為1.5～16km/h,，藥箱藥液量的變化對整機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.
