  【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,全區沒有一家農機生產企業,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農牧業生產需求,不能很好地發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,西藏自治區農業農村廳組織開展了多功能青稞割捆機田間性能測試現場活動。
 
  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,大大提高了作業效率,有效降低了作業損失?;顒蝇F場,測試人員現場查看了機具的安全性、適應性和作業穩定性,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、坡耕地等特殊作業環境,為青稞割捆機技術進一步熟化,在全區示范推廣應用奠定了堅實的基礎。
