  【中國(guó)農(nóng)機(jī)網(wǎng) 市場(chǎng)行情】 植保無(wú)人機(jī)是單旋翼好還是多旋翼好?選擇電動(dòng)的還是油動(dòng)的?輪式拖拉機(jī)和履帶式拖拉機(jī)你更喜歡哪一個(gè)?二者有什么區(qū)別?聯(lián)合收割機(jī)全喂入式和半喂入式哪個(gè)性價(jià)比更高?下面小編就來(lái)一一比較一下:
 
  1、單旋翼植保無(wú)人機(jī)和多旋翼植保無(wú)人機(jī)
 
  多旋翼:續(xù)航較弱,載重和飛行速度適中,可以垂直起降,飛行操作更為靈活,可以空中懸停,受周圍環(huán)境影響較小,適用于環(huán)境比較復(fù)雜的農(nóng)田區(qū)域。

  單旋翼:從飛行速度、靈活度、穩(wěn)定性、載重、續(xù)航能力等方面來(lái)說(shuō),性能都比較適中,適合廣幅作業(yè)。
 
  總結(jié):如果田地比較分散,作業(yè)面積十幾畝或數(shù)十畝,選擇多旋翼較為合適;若作業(yè)面積有數(shù)千畝就選擇單旋翼;假如作業(yè)面積達(dá)到上萬(wàn)畝,用固定翼更為合適,固定翼式無(wú)人機(jī)具有續(xù)航強(qiáng)、載重大、飛行快、效率高的特點(diǎn),多用于農(nóng)田信息采集和農(nóng)田遙感,也可以用于農(nóng)林植保作業(yè)。
 
  無(wú)人機(jī)按動(dòng)力來(lái)分的話分為電動(dòng)型和油動(dòng)型。電動(dòng)型操作簡(jiǎn)單,輕巧靈活,故障率低和維修簡(jiǎn)單;油動(dòng)型續(xù)航時(shí)間長(zhǎng),載荷量大,能夠覆蓋大面積的農(nóng)田,但操控要求高,價(jià)錢昂貴,而且國(guó)內(nèi)單戶的種植面積較小,土地分散,因此油動(dòng)型無(wú)人機(jī)使用較少。
 
  2、輪式拖拉機(jī)和履帶式拖拉機(jī)
 
  履帶式拖拉機(jī):這種拖拉機(jī)是通過(guò)一條卷繞的環(huán)形履帶支承在地面上,驅(qū)動(dòng)輪在驅(qū)動(dòng)扭矩的作用下,通過(guò)驅(qū)動(dòng)輪上的輪齒和履帶板節(jié)銷之間的嚙合連續(xù)不斷地把履帶從后方卷起,從而推動(dòng)拖拉機(jī)向前行駛。因接地面積相比輪式拖拉機(jī)更多,所以在相同馬力時(shí),其牽引力更大;具有接地面積大、對(duì)土壤壓實(shí)及傷害小、不易打滑、更容易發(fā)揮牽引性能的特點(diǎn),同時(shí)抗顛簸性能好;能夠用于其它類型拖拉機(jī)難以勝任的開(kāi)荒、深翻和農(nóng)田基本建設(shè)等繁重的工作。

  輪式拖拉機(jī):和履帶式相比,輪式拖拉機(jī)行駛速度快、作業(yè)效率高且運(yùn)動(dòng)噪聲低,野外、城市環(huán)境都可以;缺點(diǎn)是越障能力、地形適應(yīng)能力差,地形不能太復(fù)雜,如上樓梯難以實(shí)現(xiàn)。大馬力輪式拖拉機(jī)適于大農(nóng)場(chǎng)配帶寬幅農(nóng)具進(jìn)行高速作業(yè)。目前國(guó)內(nèi)使用輪式拖拉機(jī)較為普遍。

  3、全喂入收割機(jī)與半喂入收割機(jī)
 
  全喂入聯(lián)合收割機(jī)是指割臺(tái)切割下來(lái)的谷物全部進(jìn)入滾筒脫粒的聯(lián)合收割機(jī),體積大,適合大規(guī)模收割作業(yè);半喂入聯(lián)合收割機(jī)則是指割臺(tái)切割下來(lái)的作物僅穗頭部進(jìn)入脫粒滾筒脫粒的聯(lián)合收割機(jī),一般只用于收割小麥和水稻。
 
  全喂入式結(jié)構(gòu)簡(jiǎn)單便于維修,操作便捷,收獲時(shí)不需對(duì)行,收獲速度較快,價(jià)格較低,機(jī)具的適用性高,既能收割水稻、小麥,又能收割玉米、油菜、大豆等作物,一機(jī)多用;缺點(diǎn)是含雜率及破損率高,油耗相對(duì)較高;作業(yè)時(shí)會(huì)將秸稈揉碎,使秸稈的用途大大減少,一般只能用于還田;另外收割的水稻脫粒后的品質(zhì)較差。

  半喂入式大多采用進(jìn)口柴油發(fā)動(dòng)機(jī),質(zhì)量可靠,動(dòng)力充足,耗油量相對(duì)較低;割樁的高度可以控制在3厘米,有利于倒伏的收割及來(lái)年的耕作;同時(shí)脫粒干凈,處理能力強(qiáng),浪費(fèi)少,濕脫性能強(qiáng),且動(dòng)力消耗??;半喂入式技術(shù)含量高,自動(dòng)化程度高,可整體保留稻稈,留低茬。另外含雜率相對(duì)較低,有利于送入烘干機(jī)進(jìn)行烘干。缺點(diǎn)是整機(jī)價(jià)格高,結(jié)構(gòu)復(fù)雜,一旦出現(xiàn)故障,維修麻煩,維修費(fèi)用高。
 
  結(jié)語(yǔ)
 
  還是那句話,選擇哪種機(jī)器遵循的原則就是“因地制宜”,根據(jù)自身需求和地形地理?xiàng)l件,并綜合考慮價(jià)格、補(bǔ)貼等因素,希望這篇文章可以對(duì)農(nóng)民朋友和農(nóng)機(jī)手有所幫助。
