| 摘 要： | 为缓解我国秸秆焚烧及废弃所带来的资源浪费和环境污染等问题,设计了秸秆深施还田机,可一次完成秸秆捡拾、切碎和深施还田作业。同时,对其秸秆深施装置的秸秆深施量进行了正交试验研究,试验结果表明:秸秆含水率对秸秆深施量影响较大,深施螺旋转速次之,秸秆长度影响较小;秸秆深施量随深施螺旋转速的增大而增加,随秸秆长度和秸秆含水率的增大而减少。在该试验条件下,深施螺旋转速为540r/min、秸秆含水率为1 0%、秸秆长度为5 mm时,秸秆深施量最大。

| Abstract: | In order to alleviate the wasteful resource and environmental pollution problem which are caused by burning, wasting and low utilization rate of straw in China, designing the straw deep-application returning machine that can simul-taneously finish the task of picking, chopping and deep-application returning straw an operation.After analyzing the data of the amount of straw deep-application which can be found in straw deep-application device in orthogonal experiment, it showed that: the water ratio of straw had the biggest influence on the amount of straw deep -application and the influ-ence of the rotate speed of deep-application helix was smaller than straw moisture content.The length of straw ' s influ-ence was the smallest among the three elements.Also, the experiment showed that:the amount of straw deep-application had been increased when the rotate speed of deep-application helix improved while the water ratio of straw and the length of straw decreased at the same time.Under the condition of the test, when the rotate speed of deep-application is 540 r/min, the water ratio of straw is 10%and the length of straw is 5mm, the amount of straw deep-application is the largest. |
