2、極大的人力和物力的同時(shí),清雪效果還不好,不能及時(shí)的清掃積雪,導(dǎo)致壓榨后的積雪更難清理。因此,我們要尋找一種高效,而成本不高的清雪方法成為當(dāng)務(wù)之急。本文研究的對(duì)象為氣力式小型除雪機(jī)的結(jié)構(gòu)設(shè)計(jì),通過對(duì)鏟雪裝置進(jìn)行結(jié)構(gòu)設(shè)計(jì)及氣力傳動(dòng)的設(shè)計(jì),設(shè)計(jì)出一種規(guī)模小氣動(dòng)式清雪車,用于工作環(huán)境,家庭,社區(qū)道路積雪的清除,從而方便人們出行,免去可預(yù)知的安全問題。通過本題目設(shè)計(jì),也能夠進(jìn)一步理解機(jī)械原理、農(nóng)用機(jī)械設(shè)計(jì)、氣壓傳動(dòng)等專業(yè)課程知識(shí),掌握專用機(jī)械設(shè)計(jì)的原理和方法。關(guān)鍵詞:氣力式除雪機(jī)初雪鏟機(jī)構(gòu)氣缸;IV西安思源學(xué)院畢業(yè)論文(
