This topic design of crawler type sprayer can satisfy the fruit wood machinery operation agronomic requirements, realize the spray, reasonable design, simple structure, convenient operation, under the condition of improving the utilization of pesticide, and can meet the requirements of environmental protection, high efficiency, realize the high efficiency, energy saving, environmental protection requirements. Keywords: Spray 。 Efficiency 。目前我國(guó)植保機(jī)械的發(fā)展程度還處于一個(gè)快速發(fā)展期,隨著農(nóng)業(yè)的發(fā)展,想輔的農(nóng)業(yè)機(jī)械也要更著一并向前改進(jìn),在噴霧機(jī)這一研究領(lǐng)域,根據(jù)液壓泵、風(fēng)機(jī)、噴射部件、噴頭、噴嘴的形狀規(guī)格不同,同時(shí)可以應(yīng)用到不同經(jīng)濟(jì)作物的施肥作業(yè)。另外,我國(guó)南方地區(qū),山區(qū)和丘陵約占60%以上,道路路況差,機(jī)械行走困難;果林行間機(jī)械化作業(yè)難,根據(jù)我國(guó)南方噴霧機(jī)發(fā)展現(xiàn)狀,設(shè)計(jì)出果林丘陵履帶噴霧機(jī)可以滿足其經(jīng)濟(jì)作業(yè)的要求。4 整體方案設(shè)計(jì)如圖1所示,該機(jī)由動(dòng)力系統(tǒng)[3]、行走系統(tǒng)、噴霧系統(tǒng)、操縱控制系統(tǒng)和機(jī)架等部件組成。 行走系統(tǒng)支架操作系統(tǒng)動(dòng)力系統(tǒng)噴霧系統(tǒng) 圖1 丘陵履帶式果園噴霧機(jī) Fig1 Hilly crawler orchard sprayer 作
