联合收获机是小麦机收的关键,机具的状态如何将决定机收的成败,而做好小麦联合收割机作业前的各项检修与保养,对于延长机具使用寿命,提高其安全性和作业效率确保机收取得成功至关重要。一、做好机具作业前的各项技术检查1、检查切割器的技术状态。主要检查刀片是否完好,刀片固定是否牢固,割刀间隙、压刃器间隙是否合理,活动刀片与护刃器中心线是否重合。2、检查脱粒间隙的均匀性和安装是否合乎技术要求。若脱粒不均匀,工作时即可造成脱粒 Combine harvester is the key to the harvest of wheat, how the status of the machine will determine the success or failure of the machine, and do all the maintenance and repair work before the combine harvester, which can prolong the service life of the machine and improve its safety and work efficiency It is important to ensure that the machine is successfully received. First, do a good job before the technical inspection of the machine 1, check the technical status of the cutter. The main check whether the blade is intact, the blade is fixed firmly, knife gap, blade clearance is reasonable, the active blade and the guard blade center line coincide. 2, check the uniformity of threshing gap and whether the installation meets the technical requirements. If the threshing uneven, working can cause threshing
