4LZ-2.5型纵向轴流全喂入联合收割机是针对我国联合收获机在大草谷比和湿脱湿分离作业条件下损失大、效率低、可靠性差等问题,围绕高效纵轴流脱粒分离、清选装置,整合国内优势力量,自主创新研究适合中国国情的新一代机型。总体设计新颖、合理、结构紧奏、使用可靠、操作简单、适合大田作业等优点。总损失率、含杂率等指标均达到或超过国家行业标准的要求,在国内全喂入联合收割机中处于领先水平。
The 4LZ-2.5 longitudinal axial flow full-feed combine harvester is aimed at the problem of large loss, low efficiency and poor reliability of the combine harvester in the conditions of separation and wet dehumidification in the Grand Grass Valley, Cleansing devices, integration of domestic strengths, independent innovation to study the new generation of models suited to China’s national conditions. The overall design is novel, reasonable, compact structure, reliable, easy to operate, suitable for fieldwork and other advantages. The total loss rate, impurity content and other indicators have reached or exceeded the requirements of national industry standards, all in the domestic feed combine harvester at the leading level.
