摘  要:
进行苜蓿草压扁试验台的研制,以获取苜蓿草最佳压扁效果参数。结合苜蓿草压扁效果的影响因素:压料间隙、苜蓿草田间长势、刈割压扁机作业行驶速度、压料辊转速以及预紧机构初始预紧力,进行了压扁装置、驱动装置、间隙调节机构及数据采集系统的设计。利用试验台改变压料间隙、苜蓿草喂入量、喂入速度及压料辊转速等,可对苜蓿草的压扁效果进行多因素正交试验。试验结果表明:压料辊压力变化具有一定规律,试验台可以有效模拟真机工况。各影响因素中,喂入量对压扁后粗蛋白质质量分数的影响最大,其次分别为压料间隙、喂入速度和压料辊转速。

摘  要:
To acquire better flattening performance of the alfalfa cutting and flattening machine,a kind of test bench was proposed. According to alfalfa flattening impact factors,including flattening gap and velocity,alfalfa growth,machine walking velocity and so on,the flattening device,drive system and data acquisition system have been designed. The multi-factors orthogonal test for alfalfa flattening was executed by changing the flattening roll gap,flattening roll rotational speed and feeding rate on test bench. The results of validity test showed that the pressure values between flattening rolls showed a regular change,and the most significant impact factor of the nutrient content of alfalfa is the spreading quantity,followed by the roll gap,feeding rate and roll rotational speed. This alfalfa flattening test bench can simulate the actual operation effectively,and provide the guidance of alfalfa cutting and flattening machine design.
