導讀：中國一拖研制的國內(nèi)首臺丘陵山地專業(yè)型拖拉機被《2022年中國農(nóng)業(yè)年鑒》和《2022年中國農(nóng)業(yè)機械年鑒》雙雙收錄。

　　【農(nóng)機網(wǎng) 明星企業(yè)】中國一拖研制的國內(nèi)首臺丘陵山地專業(yè)型拖拉機被《2022年中國農(nóng)業(yè)年鑒》和《2022年中國農(nóng)業(yè)機械年鑒》雙雙收錄。
 
《2022年中國農(nóng)業(yè)年鑒》
 
　　《2022年中國農(nóng)業(yè)機械年鑒》收錄內(nèi)容
 
　　作為業(yè)內(nèi)頗具權威的兩部年鑒，分別以《填補了國內(nèi)丘陵山地專業(yè)型拖拉機產(chǎn)品空白，中國一拖成功研發(fā)國內(nèi)首臺丘陵山地專業(yè)型拖拉機》《中國一拖實現(xiàn)國內(nèi)丘陵山地專業(yè)型拖拉機產(chǎn)品國產(chǎn)化替代，解決我國丘陵山區(qū)農(nóng)機“無好機用”的問題》為題將該產(chǎn)品載入年鑒，代表了全國農(nóng)機行業(yè)對該產(chǎn)品的高度認可。
 

 

「東方紅MH804產(chǎn)品」
 
　　額定功率為80馬力，最大爬坡度可達25°(較傳統(tǒng)平地拖拉機提升了10°以上)，最小轉向半徑達到3m(較同功率傳統(tǒng)拖拉機轉向半徑減小了1~1.5m以上)，極限傾翻角可達35°以上，制動減速度為4.5m/s2(較同功率傳統(tǒng)拖拉機制動性提升20%~30%)，具備正反雙向駕駛(駕駛室雙向調(diào)整)功能，主要技術指標完全滿足丘陵山區(qū)作業(yè)需求。
 
　　東方紅MH804采用的核心技術主要有折腰扭腰轉向技術、雙向駕駛室技術、四輪制動技術、電液比例輸出技術等，均由中國一拖自主研發(fā)完成，關鍵零部件的自主化率達到95%，整機成本僅比同功率傳統(tǒng)拖拉機增加了20%~25%，保障了我國對丘陵山區(qū)專用拖拉機產(chǎn)品及技術的自主、安全、可控。
 
　　目前，東方紅MH804丘陵山區(qū)拖拉機已完成了試制與功能性驗證，正在開展最終改進與生產(chǎn)準備，計劃于下半年全面推向市場。 

  

　　我國丘陵山區(qū)耕種收綜合農(nóng)業(yè)機械化率不到50%，低于全國平均水平20個百分點，是我國農(nóng)業(yè)機械化的突出短板。拖拉機為各種農(nóng)機具提供動力和搭載平臺，是丘陵山區(qū)農(nóng)業(yè)機械化的關鍵與核心所在。傳統(tǒng)拖拉機在動力性、坡道通過性、穩(wěn)定性、制動性、轉向機動性等方面難以滿足我國丘陵山區(qū)地形及作業(yè)環(huán)境需求。
 
　　在此背景下，中國一拖以解決我國丘陵山區(qū)農(nóng)機“無好機用”難題為目標，自2020年起，分別對我國川中丘陵、黃土丘陵、閔浙丘陵、兩廣丘陵等多個典型丘陵山區(qū)作業(yè)特點及農(nóng)機市場情況開展了多次專項調(diào)研，在充分考慮丘陵山區(qū)農(nóng)機作業(yè)必要技術功能的前提下，盡可能優(yōu)化整機成本，最終確定了“高效實用”的丘陵山區(qū)拖拉機技術路線，自主研發(fā)了滿足黃土丘陵地區(qū)作業(yè)的東方紅MH804型丘陵山地專用拖拉機產(chǎn)品。
 
　　此外，中國一拖在國家相關部委及國機集團的支持下，將開展適合川中丘陵、兩廣丘陵、云貴丘陵等地塊更小、地形更復雜地區(qū)作業(yè)特點的SH30-50系列丘陵山區(qū)拖拉機的研發(fā)工作；并同時針對湖南、江西等江南丘陵地區(qū)及河谷地作業(yè)需求，研發(fā)專用的水旱兼用輪式拖拉機及輕型水田履帶拖拉機產(chǎn)品。從而形成基本滿足我國不同丘陵山區(qū)作業(yè)差異化需求的丘陵山區(qū)專用拖拉機產(chǎn)品體系，助力我國丘陵山區(qū)農(nóng)業(yè)機械化率持續(xù)提升。
