導讀:近日,西藏自治區(qū)農業(yè)農村廳組織開展了多功能青稞割捆機田間性能測試現(xiàn)場活動。

  【農機網 地方農機】青稞是西藏主要糧食作物,種植農藝復雜,機械化收獲存在諸多問題。一直以來,全區(qū)沒有一家農機生產企業(yè),農機裝備全部依靠從內地引進,許多農機裝備不能滿足我區(qū)農牧業(yè)生產需求,不能很好地發(fā)揮農機裝備支撐保障作用,存在使用不便、閑置率、故障率、作業(yè)損失率高等問題。為貫徹落實中央1號文件精神,深化“青稞機械化低損收獲裝備適應性改進”,加快多功能機具推廣應用。近日,西藏自治區(qū)農業(yè)農村廳組織開展了多功能青稞割捆機田間性能測試現(xiàn)場活動。
 
  青稞割捆機針對青稞秸稈柔性大,穗頭相互纏繞,導致割捆過程中易堵塞、易脫穗,造成青稞穗粒損失大等問題,采用優(yōu)化設計收割部件、夾持機構、打結機構和割捆傳送機構等方法,大大提高了作業(yè)效率,有效降低了作業(yè)損失。活動現(xiàn)場,測試人員現(xiàn)場查看了機具的安全性、適應性和作業(yè)穩(wěn)定性,并分別對履帶式青稞割捆機等3款機型進行機具原地轉向、割捆速度、割臺寬幅、割茬高度等基本參數測試,從測試情況來看,達到了預期設計效果,特別適用于小地塊、泥濘田、坡耕地等特殊作業(yè)環(huán)境,為青稞割捆機技術進一步熟化,在全區(qū)示范推廣應用奠定了堅實的基礎。
