一、松土機是什么
松土機是土(tu)(tu)(tu)(tu)(tu)(tu)方(fang)施工中用齒形松(song)土(tu)(tu)(tu)(tu)(tu)(tu)器耙松(song)硬土(tu)(tu)(tu)(tu)(tu)(tu)、凍土(tu)(tu)(tu)(tu)(tu)(tu)、舊路面乃至中等硬度巖(yan)石的(de)機械。按(an)松(song)土(tu)(tu)(tu)(tu)(tu)(tu)器與拖拉(la)機的(de)連接形式(shi),有拖式(shi)和懸(xuan)掛(gua)式(shi)兩種。利用拖拉(la)機提供的(de)牽引力(li)及松(song)土(tu)(tu)(tu)(tu)(tu)(tu)器重(zhong)量使耙齒切(qie)入土(tu)(tu)(tu)(tu)(tu)(tu)內,翻松(song)硬土(tu)(tu)(tu)(tu)(tu)(tu),機械通過后(hou)留下松(song)土(tu)(tu)(tu)(tu)(tu)(tu)地帶。常用于(yu)推土(tu)(tu)(tu)(tu)(tu)(tu)機或鏟(chan)運(yun)機作(zuo)業前的(de)預先翻松(song)作(zuo)業。
與傳統的打(da)眼放炮施(shi)(shi)工(gong)方(fang)法(fa)相比,具有施(shi)(shi)工(gong)工(gong)藝(yi)簡化、施(shi)(shi)工(gong)機具減少、生產率高、生產安全性好等優點,為土石方(fang)工(gong)程施(shi)(shi)工(gong)的主要準備作業機種。
二、松土機的結構組成有哪些
松(song)土(tu)機(ji)(ji)主(zhu)要(yao)由(you)電動(dong)(dong)機(ji)(ji)、減(jian)速齒(chi)輪、行走機(ji)(ji)構、松(song)土(tu)鏟(chan)、深度(du)調節機(ji)(ji)構等組(zu)(zu)成。電動(dong)(dong)機(ji)(ji)提供動(dong)(dong)力,通(tong)過聯軸器與減(jian)速齒(chi)輪軸連(lian)接。工作部件由(you)刀盤和(he)立式(shi)松(song)土(tu)鏟(chan)組(zu)(zu)成,分為兩組(zu)(zu),由(you)減(jian)速齒(chi)輪帶動(dong)(dong)。深度(du)調節機(ji)(ji)構由(you)手柄、鏈輪及鏈條組(zu)(zu)成,通(tong)過改變機(ji)(ji)架的(de)高度(du)實現松(song)土(tu)深度(du)的(de)調節。
三、通用型松土機是什么
通用型松(song)(song)土(tu)機可(ke)根(gen)據不同作(zuo)業要求,更換不同形狀(zhuang)的(de)松(song)(song)土(tu)鏟(chan)(chan)或改(gai)變其(qi)排列方式(shi)(shi),呈不同的(de)作(zuo)業狀(zhuang)態。機架呈框架式(shi)(shi),可(ke)在前(qian)后(hou)橫梁(liang)上換裝不同形式(shi)(shi)的(de)松(song)(song)土(tu)鏟(chan)(chan),或改(gai)變松(song)(song)土(tu)鏟(chan)(chan)的(de)排列方式(shi)(shi)。如(ru)果(guo)在前(qian)橫梁(liang)上間隔(ge)70厘米(間距可(ke)調)安(an)裝三組(zu)較(jiao)淺的(de)松(song)(song)土(tu)鏟(chan)(chan),在后(hou)橫梁(liang)上對應安(an)裝三組(zu)較(jiao)深(shen)(shen)的(de)松(song)(song)土(tu)鏟(chan)(chan),即可(ke)進行(xing)分層深(shen)(shen)松(song)(song)作(zuo)業,松(song)(song)土(tu)深(shen)(shen)為30~50厘米。如(ru)果(guo)在前(qian)橫梁(liang)上間隔(ge)70厘米安(an)裝三組(zu)較(jiao)淺的(de)松(song)(song)上鏟(chan)(chan),而在后(hou)橫梁(liang)上交錯安(an)裝四(si)組(zu)同樣(yang)的(de)松(song)(song)土(tu)鏟(chan)(chan),作(zuo)業間隔(ge)為35厘米,可(ke)在一般農田中進行(xing)耕深(shen)(shen)為20~30厘米的(de)全(quan)面深(shen)(shen)松(song)(song)作(zuo)業。
這種松土(tu)機作業(ye)后既(ji)疏松了(le)深(shen)層(ceng)土(tu)壤,又不打亂土(tu)層(ceng),從而(er)改善(shan)了(le)土(tu)壤的(de)理化性狀,有(you)利于蓄(xu)水保(bao)墑,對低(di)洼(wa)地的(de)深(shen)松可(ke)以加速地表水下(xia)滲,是已耕(geng)地排(pai)除耕(geng)層(ceng)水分過多的(de)有(you)效措施。
