多功能刷種機作原理：

物(wu)料進入刷種(zhong)(zhong)(zhong)筒(tong)(tong)內，在彈性(xing)尼龍的推動作(zuo)用下，使種(zhong)(zhong)(zhong)子與脫絨筒(tong)(tong)壁、種(zhong)(zhong)(zhong)子與種(zhong)(zhong)(zhong)子之間(jian)相(xiang)互磨檫去(qu)除表面的絨毛。脫下的絨毛被(bei)風機吸走，進入除塵器，沉降后定期(qi)排放(fang)。達到初(chu)部清選的目的。物(wu)料依次(ci)通過三(san)個(ge)刷種(zhong)(zhong)(zhong)筒(tong)(tong)后，好種(zhong)(zhong)(zhong)子從第三(san)筒(tong)(tong)排出，進入下一道清選工序。

主要適(shi)用于無殼南(nan)瓜(gua)籽的(de)(de)脫(tuo)絨，脫(tuo)絨后種子表面光滑，流動(dong)性好(hao)，易于清選。包衣時種衣劑的(de)(de)表面附著力強，包衣效果(guo)好(hao)。

多功能刷種機調整

(1）電機軸與主軸之(zhi)間皮帶張緊度的調節

當皮帶張緊(jin)度(du)需要調節時(shi)，首(shou)先(xian)松開電機與電機座(zuo)的四個螺(luo)栓，順(shun)著電機座(zuo)上的長孔移動電機，使(shi)皮帶張緊(jin)適(shi)當，然后(hou)擰緊(jin)螺(luo)栓。

(2>刷種(zhong)間隙和刷種(zhong)時間的調節(jie)

種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)開始加工時(shi)(shi)(shi)，從出料口(kou)觀察(cha)刷(shua)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)情(qing)況(kuang)，若(ruo)(ruo)有種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)破碎現(xian)象，則應增大刷(shua)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)間隙(xi);若(ruo)(ruo)刷(shua)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)不*時(shi)(shi)(shi)，則應減小刷(shua)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)間隙(xi);若(ruo)(ruo)刷(shua)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)效(xiao)果(guo)好時(shi)(shi)(shi)，則將出料口(kou)擋板(ban)降低，使種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)在(zai)刷(shua)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)筒內停留時(shi)(shi)(shi)間（即刷(shua)種(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)時(shi)(shi)(shi)間)縮短，增加生產率。

注意:此調整均應(ying)停機(ji)進行。

(3）主軸轉(zhuan)速的調節

通過更(geng)換電機(ji)皮(pi)帶輪或(huo)調節電流頻率(lv)來實現(xian)。轉速越高，刷種效果越明顯(xian)，反之亦然(ran)。更(geng)換皮(pi)帶輪后，皮(pi)帶的(de)張緊度(du)要作相應的(de)調整。

調整毛刷與篩(shai)筒(tong)筒(tong)壁(bi)之(zhi)間(jian)(jian)的(de)間(jian)(jian)隙、改變主軸(zhou)轉速或控制(zhi)排料時間(jian)(jian)等均可改變刷種(zhong)(zhong)強度，以適應(ying)不(bu)同(tong)種(zhong)(zhong)子的(de)表面(mian)處(chu)理，但刷種(zhong)(zhong)強度不(bu)宜(yi)過(guo)高，以免使種(zhong)(zhong)子表皮產生(sheng)損傷或種(zhong)(zhong)溫增加(jia)過(guo)多，降(jiang)低種(zhong)(zhong)子的(de)發芽(ya)率。
