農(nóng)機網(wǎng) 熱點關注】 為掌握廣西現(xiàn)階段在用果園軌道
運輸機和
微耕機的整體質量狀況,確保農(nóng)機購置補貼政策發(fā)揮實效,促進農(nóng)業(yè)機械化又好又快發(fā)展,2021年,廣西壯族自治區(qū)農(nóng)業(yè)農(nóng)村廳會同自治區(qū)農(nóng)機中心開展了在用果園軌道運輸機和微耕機質量調查,并于近日對調查結果進行了通報。
果園軌道運輸機
本次共調查了湖北華聯(lián)機械制造實業(yè)股份有限公司等12家生產(chǎn)企業(yè)的12個型號120臺產(chǎn)品及用戶。對廣西全區(qū)2020年購買且使用一個作業(yè)季節(jié)以上(含)的果園軌道運輸機產(chǎn)品采取分層抽樣方法,共抽出120臺果園軌道運輸機產(chǎn)品,涉及12家企業(yè)生產(chǎn)的12個型號(見表1)。涵蓋的地區(qū)有柳城縣、鹿寨縣、融安縣、融水縣、桂林市雁山區(qū)、桂林市臨桂區(qū)、靈川縣、興安縣、全州縣、恭城縣、陽朔縣、防城港市港口區(qū)、東興市、欽州市欽南區(qū)、浦北縣、貴港市港北區(qū)、貴港市港南區(qū)、貴港市覃塘區(qū)、桂平市、平南縣、百色市右江區(qū)、百色市田陽區(qū)、平果市、田林縣、凌云縣、樂業(yè)縣、隆林縣、大化縣28個縣(市、區(qū))。
調查結果顯示,雖然絕大多數(shù)運輸機及其運輸線性能安全可靠,無故障發(fā)生,但仍有部分產(chǎn)品一般性故障出現(xiàn)較多,主要表現(xiàn)在動力不足、制動性能差、滾輪裂開、傳動箱有異響、軸承易損壞、
控制器損壞、電瓶不耐用,以及軌道支撐柱下沉等。分析原因有以下幾方面:一是機型動力選配不當;二是為降低成本外購件質量差;三是為趕工期,不考慮現(xiàn)場實際,降低安裝調試標準。
調查中發(fā)現(xiàn)廣西果園軌道運輸機總工作時長總體偏低,使用率低,機具使用小于200小時(含200小時)的最多,占50.8%,折合約25工作日(每日按8小時計);使用500小時以上的占16.7%,折合約62.5工作日(每日按8小時計)偏少。分析原因有以下幾方面:一是絕大部分運輸機在果園種植區(qū)域使用,用于平時施肥、灑藥、收獲摘果等,屬季節(jié)性使用,使得運輸機作業(yè)周期偏長,但作業(yè)時間卻較短;二是水產(chǎn)養(yǎng)殖區(qū)域運輸機使用率較高(投放餌料),但機具較少。
微耕機
本次共調查了威馬農(nóng)機股份有限公司等10家生產(chǎn)企業(yè)的10個型號100個產(chǎn)品及用戶,對2019年購買且使用一個作業(yè)季節(jié)以上(含)的微耕機產(chǎn)品及其用戶采取分層抽樣方法,確定100臺微耕機產(chǎn)品,涉及10家企業(yè)生產(chǎn)的10個型號(見表1)。涵蓋的地區(qū)有南寧市西鄉(xiāng)塘區(qū)、馬山縣、柳城縣、鹿寨縣、三江縣、融水縣、桂林市臨桂區(qū)、靈川縣、興安縣、全州縣、龍勝縣、荔浦市、恭城縣、欽州市欽北區(qū)、玉林市玉州區(qū)、北流市、容縣、興業(yè)縣、靖西市、田林縣、樂業(yè)縣、隆林縣、河池市宜州區(qū)、都安縣、巴馬縣25個縣(市、區(qū))。
調查顯示,部分微耕機一般性故障較多,用機戶年齡偏大,機具使用率偏底。調查中發(fā)現(xiàn)大部分在用微耕機在產(chǎn)品質量、性能穩(wěn)定、安全防護等方面都取得了較大進步,深受農(nóng)戶喜愛,但仍有部分產(chǎn)品存在有少量的嚴重故障和較多的一般性故障。其中,嚴重故障表現(xiàn)為發(fā)動機轉子卡死、不轉動、動力不足等故障,一般性故障表現(xiàn)為發(fā)動機漏油、化油器損壞、鏈條斷、火花塞易損壞、齒輪箱油封損壞、高速擋齒輪箱內(nèi)雜聲大、電路開關等故障。分析原因有以下幾方面:一是企業(yè)在動力選配上沒有把好質量關;二是在零部件采購上降低質量標準,造成總裝質量差,部件易損壞。
調查中發(fā)現(xiàn)用機戶年齡普遍偏大,40—60歲年齡段的占64%,60—70歲年齡段的占20%。微耕機總工作時長總體較短,使用率低;小于100小時的最多,占41%,折合約12.5工作日(每日按8小時計);400小時以上占7%,折合約50工作日(每日按8小時計)偏少。主要原因為農(nóng)村絕大多數(shù)青壯年外出務工,機具使用主要以中老年人自家耕用為主。微耕機主要使用于丘陵旱地、果園、茶園等旋耕、除草,極少數(shù)為水田耕用。因此,作業(yè)時間較短,導致工作時長和工作量偏少。
通過本次調查掌握了廣西各農(nóng)機補貼機具產(chǎn)品質量信息,摸清了在用果園軌道運輸機和微耕機的質量狀況、存在問題以及農(nóng)戶對機械化生產(chǎn)的迫切需求,為進一步提升農(nóng)機產(chǎn)品質量、售后服務和完善農(nóng)機質量投訴體系建設打下良好基礎。
