    摘要:

    對(duì)4HLB—2型花生聯(lián)合收獲機(jī)清土裝置進(jìn)行了機(jī)構(gòu)運(yùn)動(dòng)特性分析和清土效果試驗(yàn)研究,。拍土板拍擊線速度,、轉(zhuǎn)動(dòng)角速度均隨時(shí)間呈正弦曲線規(guī)律變化,，在一個(gè)清土周期中共完成2次拍土過(guò)程,，且出現(xiàn)2次拍土作用最強(qiáng)烈狀態(tài),。清土通道后半程的清土效果要優(yōu)于前半程,，拍土板由兩端向中間拍土強(qiáng)度逐漸降低,，清土通道中間段存在無(wú)效拍擊區(qū),。清土試驗(yàn)表明，清土率主要決定于花生果系被拍土板拍擊的次數(shù),，而落果損失主要決定于拍土板角振幅大小,，實(shí)際作業(yè)時(shí)應(yīng)選定高清土頻率、小角振幅的作業(yè)參數(shù),。

    Abstract:

    Motion analysis and experiment of clod cleaning effect were conducted on clod cleaner of 4HLB—2 type peanut combine harvester. Linear velocity and angular velocity of flap plate varied with time according to sinusoidal law. During one clod cleaning cycle, two flapping processes were completed, and the most intense flapping status appeared twice. Clod cleaning effect of the second half of the flapping path was better than that of the first half. The flapping strength of the plates decreased from the ends to the middle, and some of the middle path was viewed as invalid section. Clod cleaning experiment showed that clod cleaning rate was mainly affected by flapping times taken by peanut clusters, and dropped peanut loss was mainly determined by angle amplitude of the flap plates. Higher vibration frequency and smaller angel amplitude were preferred during field working. 
