【割草機特點(dian)】割草機的特點(dian)是什么 割草機的發展
割草機的特點是什么
割草機特點是(shi)工作平(ping),操作簡單(dan),對(dui)所需(xu)要切(qie)(qie)(qie)(qie)割(ge)(ge)的對(dui)象(xiang),主要是(shi)草(cao)(cao)類的切(qie)(qie)(qie)(qie)割(ge)(ge)性強,適用(yong)(yong)于高(gao)產(chan)草(cao)(cao)場與大型公(gong)園等。割(ge)(ge)草(cao)(cao)機依(yi)靠切(qie)(qie)(qie)(qie)割(ge)(ge)器上(shang)動刀和定刀的相對(dui)剪切(qie)(qie)(qie)(qie)運動切(qie)(qie)(qie)(qie)割(ge)(ge)草(cao)(cao)類,其(qi)特點是(shi)割(ge)(ge)茬整(zheng)齊(qi),所需(xu)功(gong)率(lv)較小,但對(dui)牧草(cao)(cao)的適應性差,易堵塞,適用(yong)(yong)于平(ping)坦天然的草(cao)(cao)場和人工草(cao)(cao)場作業。80年代中期開始生產并使用旋轉式割草機。依靠高速旋轉刀盤上的刀片沖擊切割牧草。隨著科技的提高,新改良的割草機產品的工作能力增強許多,在速度方面提高很多,節省了除草工人的作業時間,節約了大量的人力資源。
割草機的發展
中(zhong)國(guo)在20世紀20年(nian)代開(kai)端運用蓄力來去式割草機,50年代初期和后(hou)期先(xian)后(hou)開發出產(chan)蓄力和遷(qian)延機牽引來去(qu)式(shi)割(ge)草(cao)機,隨(sui)著人工草(cao)場的發展,70年代中(zhong)期開發(fa)出產(chan)并使用改良扭轉式割(ge)草(cao)機。在畜牧業(ye)機械化高度發(fa)展(zhan)的(de)國家,新(xin)型(xing)割(ge)草(cao)機的(de)發(fa)展(zhan)趨勢正向著高速、節能的(de)方(fang)向開展(zhan)發(fa)明。
系統組成:這款小型割草機(ji)結構上(shang)可以分為5個系(xi)統(tong):1、動力系(xi)統(tong);2、動力傳遞系統;3、行走(zou)系統(tong);4、切割系統(tong);5、操作(zuo)系統。各系統相(xiang)互配合,完成機器自走和割草任務。

5、操作系統
操(cao)作(zuo)(zuo)(zuo)(zuo)系統(tong),以(yi)上(shang)幾個系統(tong)必須在(zai)操(cao)作(zuo)(zuo)(zuo)(zuo)系統(tong)的(de)(de)統(tong)一控制下(xia)才能完成各項作(zuo)(zuo)(zuo)(zuo)業操(cao)作(zuo)(zuo)(zuo)(zuo),操(cao)作(zuo)(zuo)(zuo)(zuo)系統(tong)處于(yu)整機的(de)(de)后部,所有的(de)(de)操(cao)作(zuo)(zuo)(zuo)(zuo)都在(zai)變(bian)速器操(cao)作(zuo)(zuo)(zuo)(zuo)桿和操(cao)作(zuo)(zuo)(zuo)(zuo)手(shou)(shou)把上(shang)完成,操(cao)作(zuo)(zuo)(zuo)(zuo)手(shou)(shou)把不僅是(shi)操(cao)作(zuo)(zuo)(zuo)(zuo)員的(de)(de)扶手(shou)(shou),它上(shang)面還安裝有各種操(cao)作(zuo)(zuo)(zuo)(zuo)手(shou)(shou)柄(bing)。這里是(shi)手(shou)(shou)把與機器的(de)(de)連接孔(kong),分為高、中、低三個連接孔(kong),操(cao)作(zuo)(zuo)(zuo)(zuo)手(shou)(shou)把可(ke)(ke)以(yi)根據操(cao)作(zuo)(zuo)(zuo)(zuo)員的(de)(de)身高,進行適當(dang)的(de)(de)調整。在(zai)操(cao)作(zuo)(zuo)(zuo)(zuo)手(shou)(shou)把的(de)(de)這一邊,安裝有變(bian)速箱(xiang)離合手(shou)(shou)柄(bing),手(shou)(shou)柄(bing)的(de)(de)下(xia)方與一根金屬拉線相(xiang)連,這個拉線的(de)(de)另一端(duan)與前面介(jie)紹(shao)的(de)(de)變(bian)速箱(xiang)壓帶輪相(xiang)連,因此變(bian)速箱(xiang)離合手(shou)(shou)柄(bing)可(ke)(ke)以(yi)控制動力向變(bian)速箱(xiang)傳遞。
在操作手把的(de)另一邊安裝有切割系統的(de)離(li)合(he)(he)(he)手柄(bing)(bing),同(tong)樣這個(ge)離(li)合(he)(he)(he)手柄(bing)(bing)的(de)下方也(ye)連接著一根金屬(shu)拉(la)線,它的(de)另一端與前(qian)面介紹的(de)這個(ge)壓(ya)帶輪(lun)(lun)(lun)相連,同(tong)理:當(dang)離(li)合(he)(he)(he)手柄(bing)(bing)處(chu)于前(qian)面位置時,拉(la)線拉(la)緊,壓(ya)帶輪(lun)(lun)(lun)靠緊皮帶,動(dong)力連接上(shang),通(tong)過皮帶將動(dong)力傳送到割臺(tai)部(bu)分;當(dang)離(li)合(he)(he)(he)手柄(bing)(bing)處(chu)于后面位置時,拉(la)線松弛(chi),壓(ya)帶輪(lun)(lun)(lun)松開動(dong)力皮帶,動(dong)力斷開,因此這個(ge)離(li)合(he)(he)(he)器(qi)手柄(bing)(bing)可以直接控制割臺(tai)的(de)運轉和停(ting)止。
這(zhe)(zhe)(zhe)是油門(men)(men)(men)控(kong)制手(shou)(shou)柄,它也是通(tong)過(guo)一根金(jin)屬拉線(xian)與(yu)發(fa)(fa)動(dong)機(ji)(ji)油門(men)(men)(men)相連的,這(zhe)(zhe)(zhe)個(ge)油門(men)(men)(men)控(kong)制手(shou)(shou)柄有三個(ge)位置區域(yu),分別(bie)(bie)是前面、中間(jian)(jian)、后面,分別(bie)(bie)對應油門(men)(men)(men)上的這(zhe)(zhe)(zhe)三個(ge)區域(yu),當(dang)(dang)手(shou)(shou)柄放在最后位置時(shi),油門(men)(men)(men)關閉(bi),當(dang)(dang)控(kong)制手(shou)(shou)柄放在中間(jian)(jian)位置時(shi),油門(men)(men)(men)適(shi)中,一般在發(fa)(fa)動(dong)機(ji)(ji)啟動(dong)時(shi),手(shou)(shou)柄放在中間(jian)(jian)位置,當(dang)(dang)手(shou)(shou)柄向前推時(shi),油門(men)(men)(men)逐漸加大。油門(men)(men)(men)越大,發(fa)(fa)動(dong)機(ji)(ji)輸(shu)出的動(dong)力(li)越強勁,在行(xing)走、收割時(shi)可(ke)以(yi)隨時(shi)調整油門(men)(men)(men)手(shou)(shou)柄位置,以(yi)獲得所需要的動(dong)力(li)。
再來看看變(bian)速(su)(su)(su)(su)(su)(su)箱(xiang)操作桿,它(ta)與變(bian)速(su)(su)(su)(su)(su)(su)箱(xiang)相連,其實就是(shi)(shi)檔(dang)(dang)(dang)位手(shou)柄(bing),發動機傳來的(de)動力(li)(li),必須經過變(bian)速(su)(su)(su)(su)(su)(su)箱(xiang)進(jin)行動力(li)(li)變(bian)換,才能(neng)輸(shu)(shu)出(chu)到行走輪,這(zhe)(zhe)款(kuan)割草機設計(ji)了(le)(le)六個(ge)前(qian)進(jin)檔(dang)(dang)(dang),兩個(ge)倒退檔(dang)(dang)(dang),可(ke)以(yi)區分為高(gao)速(su)(su)(su)(su)(su)(su)檔(dang)(dang)(dang)和低(di)(di)速(su)(su)(su)(su)(su)(su)檔(dang)(dang)(dang),它(ta)的(de)位置(zhi)(zhi)分布是(shi)(shi):當(dang)手(shou)柄(bing)處于(yu)最下面中(zhong)間位置(zhi)(zhi)時(shi),處于(yu)空擋(dang)位置(zhi)(zhi),變(bian)速(su)(su)(su)(su)(su)(su)箱(xiang)沒有動力(li)(li)輸(shu)(shu)出(chu);當(dang)手(shou)柄(bing)往左(zuo)搬(ban)(ban)時(shi),選(xuan)擇低(di)(di)速(su)(su)(su)(su)(su)(su)檔(dang)(dang)(dang)位,當(dang)手(shou)柄(bing)向右搬(ban)(ban)時(shi),選(xuan)擇高(gao)速(su)(su)(su)(su)(su)(su)檔(dang)(dang)(dang)位,具體操作是(shi)(shi)這(zhe)(zhe)樣的(de):先將(jiang)(jiang)(jiang)手(shou)柄(bing)向左(zuo)搬(ban)(ban)一次,然(ran)后(hou)將(jiang)(jiang)(jiang)手(shou)柄(bing)搬(ban)(ban)向這(zhe)(zhe)個(ge)位置(zhi)(zhi),則選(xuan)擇了(le)(le)低(di)(di)速(su)(su)(su)(su)(su)(su)一檔(dang)(dang)(dang),如果手(shou)柄(bing)搬(ban)(ban)向這(zhe)(zhe)個(ge)位置(zhi)(zhi),則選(xuan)擇了(le)(le)低(di)(di)速(su)(su)(su)(su)(su)(su)二檔(dang)(dang)(dang),這(zhe)(zhe)里就是(shi)(shi)低(di)(di)速(su)(su)(su)(su)(su)(su)三檔(dang)(dang)(dang);如果先將(jiang)(jiang)(jiang)手(shou)柄(bing)向右搬(ban)(ban)一次,然(ran)后(hou)再將(jiang)(jiang)(jiang)手(shou)柄(bing)搬(ban)(ban)向這(zhe)(zhe)個(ge)位置(zhi)(zhi),則選(xuan)擇了(le)(le)高(gao)速(su)(su)(su)(su)(su)(su)四檔(dang)(dang)(dang),依次類推(tui),這(zhe)(zhe)是(shi)(shi)高(gao)速(su)(su)(su)(su)(su)(su)五檔(dang)(dang)(dang),這(zhe)(zhe)是(shi)(shi)高(gao)速(su)(su)(su)(su)(su)(su)六檔(dang)(dang)(dang)。由(you)此可(ke)見,下面的(de)這(zhe)(zhe)兩個(ge)位置(zhi)(zhi)是(shi)(shi)高(gao)速(su)(su)(su)(su)(su)(su)擋(dang)和低(di)(di)速(su)(su)(su)(su)(su)(su)擋(dang)的(de)轉換位置(zhi)(zhi)。上面的(de)這(zhe)(zhe)個(ge)位置(zhi)(zhi)是(shi)(shi)倒檔(dang)(dang)(dang),同樣有高(gao)速(su)(su)(su)(su)(su)(su)和低(di)(di)速(su)(su)(su)(su)(su)(su)之分,選(xuan)擇方(fang)法(fa)和前(qian)進(jin)檔(dang)(dang)(dang)道(dao)理相同。正常(chang)作業(ye)時(shi)選(xuan)擇前(qian)進(jin)二檔(dang)(dang)(dang)作業(ye),牧草密度大時(shi),收割阻(zu)力(li)(li)增(zeng)加,應選(xuan)擇前(qian)進(jin)低(di)(di)速(su)(su)(su)(su)(su)(su)檔(dang)(dang)(dang)作業(ye)。運(yun)輸(shu)(shu)狀態(tai)下,可(ke)以(yi)根據需要(yao)隨時(shi)選(xuan)擇行走檔(dang)(dang)(dang)位。
