導(dǎo)讀:入冬前要對農(nóng)機(jī)的各個部位進(jìn)行除垢、清洗、調(diào)整、潤滑,氣門間隙、噴油壓力及噴油提前角等技術(shù)指標(biāo)要注意調(diào)整到規(guī)定的范圍,對離合器、制動器和操縱機(jī)構(gòu)進(jìn)行全面調(diào)整,確保拖拉機(jī)處于良好的狀態(tài),為過冬打下安全的基礎(chǔ)。

  【農(nóng)機(jī)網(wǎng) 地方農(nóng)機(jī)】 一到冬季,農(nóng)作物進(jìn)入“休眠”狀態(tài),農(nóng)機(jī)也進(jìn)入了閑置狀態(tài),一些農(nóng)機(jī)手對于農(nóng)機(jī)的保養(yǎng)不夠重視,認(rèn)為隨便保養(yǎng)保養(yǎng)就可以了。但其實(shí)不是的,農(nóng)機(jī)的保養(yǎng)跟不上,會給農(nóng)戶造成不必要的損失。那么寒冷的冬季該如何保養(yǎng)和防護(hù)農(nóng)機(jī)以便來年更好地投入農(nóng)業(yè)生產(chǎn)?
 
  入冬前要對農(nóng)機(jī)的各個部位進(jìn)行除垢、清洗、調(diào)整、潤滑,氣門間隙、噴油壓力及噴油提前角等技術(shù)指標(biāo)要注意調(diào)整到規(guī)定的范圍,對離合器、制動器和操縱機(jī)構(gòu)進(jìn)行全面調(diào)整,確保拖拉機(jī)處于良好的狀態(tài),為過冬打下安全的基礎(chǔ)。
 

  除此之外還應(yīng)注意以下幾點(diǎn):
 
  一、加強(qiáng)機(jī)體保溫
 
  1、拖拉機(jī)和其他農(nóng)業(yè)機(jī)械應(yīng)盡量停放在車庫內(nèi),防止被雨雪侵蝕和冰凍。
 
  2、檢查車輛水箱,查看防凍液抗低溫型號,不符合低溫要求的及時(shí)更換,防凍液不足的及時(shí)補(bǔ)充,未使用防凍液的將水箱放空。
 
  二、防止凍裂機(jī)件
 
  1、注意不能滿負(fù)荷大油門作業(yè),不能突然熄火和立即放水,防止機(jī)體因驟冷而開裂。放水時(shí)要打開水箱蓋和所有的放水開關(guān),務(wù)必放凈。
 
  2、適當(dāng)增大蓄電池電解液的比重(達(dá)到1.28—1.31),用補(bǔ)充充電的方法讓蓄電池保持電量充足的狀態(tài),使蓄電池不致因低溫而過多喪失電容量和凍裂蓄電池殼。
 
  三、及時(shí)更換冬季用油
 
  1、如需要使用柴油農(nóng)機(jī),可以選用凝固點(diǎn)低、流動性好的-10號、-20號輕柴油。
 
  2、對于潤滑油,應(yīng)在清洗潤滑系的基礎(chǔ)上,換用黏度較小冬用潤滑油,或者使用稠化機(jī)油,改善發(fā)動機(jī)的低溫啟動性能。
 
  四、注意駕駛陋習(xí)
 
  不注重駕駛方法,違規(guī)操作。如一些農(nóng)機(jī)手在熄火前亂轟油門, 以為能在氣缸內(nèi)存些柴油,便于下次易啟動。其實(shí),這樣做只會造成柴油在氣缸內(nèi)不能完全燃燒而造成積碳,并可能順著缸壁流入油底殼稀釋機(jī)油,不但對下次啟動絲毫無益,而且還影響機(jī)油的潤滑性能,得不償失。還有的不及時(shí)添加柴油,冬季熄火前應(yīng)向拖拉機(jī)油箱內(nèi)加滿柴油。否則,空箱內(nèi)空氣中的水蒸汽遇箱壁冷卻后液化凝結(jié)成水珠,混入柴油內(nèi),導(dǎo)致發(fā)動機(jī)無法正常工作。
 
  五、設(shè)施大棚防止大雪壓塌
 
  1、對大棚進(jìn)行加固。沿大(中)棚棚架縱向中軸線每隔2-3米用一根毛竹等支撐物對棚頂進(jìn)行支撐加固,提高大棚棚架的抗壓性,防止雪壓倒棚。
 
  3、及時(shí)清除棚頂積雪。下雪時(shí)應(yīng)及時(shí)上好草苫或保溫被,草苫或保溫被上面用防寒膜覆蓋,把緩沖室門關(guān)緊關(guān)嚴(yán),以防冷風(fēng)進(jìn)入。
 
  4、在棚頂積雪無法清除時(shí)(特別是連棟大棚),采用破膜保架的特殊應(yīng)急措施,放棄棚內(nèi)種植作物,全力保護(hù)棚架,盡量降低損失。棚架上有外遮蔭設(shè)備的,要收起收緊外遮蔭上的遮陽網(wǎng),防止雪壓毀壞。
 
  5、對溫室內(nèi)種植的瓜類、果菜類及喜光、喜溫性強(qiáng)的蔬菜有條件的農(nóng)戶可采取棚內(nèi)安裝補(bǔ)光燈、熱風(fēng)爐或電暖氣等,以增加光照提高溫度。
