摘  要:
针对原9ST-460型草地振动式间隔松土机在草原试验中出现的问题,对机具的传动系统、激振部件以及松土部件进行改进设计,并进行了草原试验。试验结果表明,改进的机具运行平稳可靠、草地作业效果好,能够满足退化草场改良的需要。作业后草地的土壤容积密度降低、含水率增加,作业后的草地3年内平均每公顷年增收155元。

摘  要:
Aimed to the problems revealed in latest grassland tests of the 9ST-460 vibration spacing scarifier,optimizations were carried out on the transmission mode of the parts,vibrating and loosening components.The results of comparing test indicated that the improved device ran steadily and showed good performance.The bulk density of soil decreased but water content increased after scarifying.The yearly average economic benefit increased by 155 RMB/hm2 in next 3 years after scarifying,which well fulfilled the requirements of grassland improvement procedure.
