一、松土機是什么
松土機是土(tu)(tu)方施(shi)工(gong)中用齒形松(song)土(tu)(tu)器(qi)耙(pa)松(song)硬土(tu)(tu)、凍土(tu)(tu)、舊路面乃(nai)至中等硬度巖(yan)石的機(ji)(ji)械。按松(song)土(tu)(tu)器(qi)與拖(tuo)(tuo)拉(la)(la)機(ji)(ji)的連接形式(shi)(shi)，有拖(tuo)(tuo)式(shi)(shi)和懸(xuan)掛式(shi)(shi)兩種。利用拖(tuo)(tuo)拉(la)(la)機(ji)(ji)提供的牽引力及松(song)土(tu)(tu)器(qi)重量使耙(pa)齒切入土(tu)(tu)內，翻松(song)硬土(tu)(tu)，機(ji)(ji)械通過后留下松(song)土(tu)(tu)地帶。常(chang)用于推(tui)土(tu)(tu)機(ji)(ji)或鏟(chan)運機(ji)(ji)作(zuo)業前(qian)的預(yu)先翻松(song)作(zuo)業。
與(yu)傳(chuan)統(tong)的(de)打(da)眼放炮施(shi)工方法相比(bi)，具(ju)有施(shi)工工藝簡(jian)化、施(shi)工機(ji)具(ju)減少、生產率高、生產安全性好(hao)等(deng)優點，為土石方工程(cheng)施(shi)工的(de)主要準(zhun)備作業機(ji)種。
二、松土機的結構組成有哪些
松(song)土(tu)機(ji)(ji)主要由電(dian)動機(ji)(ji)、減速齒輪(lun)、行走機(ji)(ji)構、松(song)土(tu)鏟(chan)、深度調節機(ji)(ji)構等(deng)組成(cheng)(cheng)。電(dian)動機(ji)(ji)提供動力(li)，通過聯(lian)軸(zhou)器(qi)與減速齒輪(lun)軸(zhou)連接(jie)。工(gong)作部件由刀(dao)盤和立(li)式松(song)土(tu)鏟(chan)組成(cheng)(cheng)，分為(wei)兩組，由減速齒輪(lun)帶動。深度調節機(ji)(ji)構由手柄(bing)、鏈輪(lun)及鏈條組成(cheng)(cheng)，通過改變機(ji)(ji)架的高(gao)度實現松(song)土(tu)深度的調節。
三、通用型松土機是什么
通用型松(song)(song)(song)土(tu)(tu)機可(ke)(ke)根據不同作(zuo)(zuo)業要求，更換不同形(xing)狀(zhuang)的松(song)(song)(song)土(tu)(tu)鏟(chan)(chan)或改變其排(pai)列(lie)方式，呈(cheng)不同的作(zuo)(zuo)業狀(zhuang)態。機架(jia)呈(cheng)框(kuang)架(jia)式，可(ke)(ke)在前(qian)后橫(heng)梁(liang)(liang)(liang)上換裝(zhuang)不同形(xing)式的松(song)(song)(song)土(tu)(tu)鏟(chan)(chan)，或改變松(song)(song)(song)土(tu)(tu)鏟(chan)(chan)的排(pai)列(lie)方式。如果在前(qian)橫(heng)梁(liang)(liang)(liang)上間(jian)隔70厘(li)米(mi)（間(jian)距(ju)可(ke)(ke)調）安裝(zhuang)三組(zu)(zu)較淺(qian)的松(song)(song)(song)土(tu)(tu)鏟(chan)(chan)，在后橫(heng)梁(liang)(liang)(liang)上對應(ying)安裝(zhuang)三組(zu)(zu)較深(shen)(shen)(shen)(shen)的松(song)(song)(song)土(tu)(tu)鏟(chan)(chan)，即可(ke)(ke)進行分(fen)層深(shen)(shen)(shen)(shen)松(song)(song)(song)作(zuo)(zuo)業，松(song)(song)(song)土(tu)(tu)深(shen)(shen)(shen)(shen)為30～50厘(li)米(mi)。如果在前(qian)橫(heng)梁(liang)(liang)(liang)上間(jian)隔70厘(li)米(mi)安裝(zhuang)三組(zu)(zu)較淺(qian)的松(song)(song)(song)上鏟(chan)(chan)，而(er)在后橫(heng)梁(liang)(liang)(liang)上交錯(cuo)安裝(zhuang)四組(zu)(zu)同樣的松(song)(song)(song)土(tu)(tu)鏟(chan)(chan)，作(zuo)(zuo)業間(jian)隔為35厘(li)米(mi)，可(ke)(ke)在一(yi)般農(nong)田中進行耕深(shen)(shen)(shen)(shen)為20～30厘(li)米(mi)的全面深(shen)(shen)(shen)(shen)松(song)(song)(song)作(zuo)(zuo)業。
這種松(song)土機作(zuo)業后既(ji)疏松(song)了深層土壤，又不打亂(luan)土層，從而改(gai)善了土壤的理化性狀，有(you)利(li)于蓄水(shui)保墑(di)，對(dui)低洼地的深松(song)可以(yi)加速地表水(shui)下(xia)滲，是已耕地排除耕層水(shui)分過多的有(you)效措施。
