用联合收割机收获小麦,一次作业可完成切割、脱粒、分离、清选、麦粒进仓和卸粮等工序。但是,机具在作业过程中,由于调整、使用不当,往往会增加各种损失(如落粒、切穗、掉穗、脱不净、破碎、漏粮和漏割)。为了减少各种损失或将其控制在一定范围内,必须在了解机具结构和工作性能的基础上,对机具各部分进行正确调整,使机具保持在最佳技术状态下作业。下面简单介绍联合收割机收获小麦损失的原因和防治措施。一、收割机喂入部分损失收割机喂入部分损失包括:拨禾损失、漏禾损失和割茬高度不当造成的损失。一般说来,三部分损失 Wheat harvest with a combine harvester, a job can be completed cutting, threshing, separation, cleaning, grain into the warehouse and unloading food and other processes. However, due to improper adjustment and improper use of the equipment during operation, various losses (such as falling, cutting ears, falling ears, shredding, crushing, missing grains and leakage) are often added. In order to reduce or control a variety of losses within a certain range, we must understand the structure and work performance of the machine on the basis of the correct adjustment of the various parts of the machine so that the machine to maintain the best technical conditions for homework. The following is a brief introduction of the harvester combine harvester loss of the causes and prevention measures. First, the harvester feed part of the loss Harvest feed part of the loss include: dial Wo loss, loss of Wo Wo and stubble height caused by improper loss. In general, three parts are lost
