草地振动式间隔松土机设计与试验（Design and Experiment on Vibration Spacing Scarifier for Meadow）
松土机 振动 草原改良 虚实耕作 设计 试验
2010/2/26
针对我国草原长期过载放牧，造成土壤板结严重，导致草原退化的问题，设计了9ST-460型草地振动式间隔松土机。该机采用间隔配置的梯形框架式松土部件，利用曲轴连杆机构产生的向上激振力，对通过松土部件的土壤进行强制振动疏松，实现了在不破坏草原植被的条件下，对高坚实度草原土壤的松土作业。田间试验表明：机具在前进速度1m/s、振动频率10.0Hz情况下，作业稳定，松土效果明显。经检测，松土平均深度20.01...
