    摘要:

    設(shè)計(jì)了結(jié)構(gòu)緊湊、轉(zhuǎn)向半徑小的履帶自走式果園定向風(fēng)送噴霧機(jī)。對(duì)傳動(dòng)系統(tǒng)、履帶行走系統(tǒng)和風(fēng)送系統(tǒng)等關(guān)鍵部件進(jìn)行了設(shè)計(jì)和計(jì)算，對(duì)定向噴霧機(jī)構(gòu)進(jìn)行了設(shè)計(jì)和試驗(yàn)驗(yàn)證。試驗(yàn)結(jié)果表明：有風(fēng)送時(shí)霧滴沉積量比無(wú)風(fēng)送時(shí)提高了42.9%，變異系數(shù)降低了18.5%；定向噴霧比普通噴霧霧滴個(gè)數(shù)提高了30.9%，變異系數(shù)降低了55.3%。

    Abstract:

    A kind of self-propelled crawler directional air-blowing orchard sprayer was developed. The working principle and transmission line of the machine were introduced firstly. Adopting theoretical calculation, the design of whole structure and the technical parameters of the key components were determined. In order to achieve the directional spraying, the multi-degree of freedom framework was designed. The experiment showed that, compared with no wind spraying, the deposit rate of droplets increased by 42.9% and the coefficient of variation decreased by 18.5%. Compared with ordinary spraying, the number of droplets increased by 30.9% and the coefficient of variation decreased by 55.3%.
