Working mechanism of vibration spacing scarifier for grassland

In order to improve the performance of the vibration spacing scarifier for grassland, the working mechanism of the equipment should be studied. The crushing mechanism under the forced oscillation of the scarifier part was discussed in the paper by carrying out the motion simulation analysis to the single set of working parts of the equipment. The working process could be divided into two alternating actions, the soil-cutting action and the soil-throwing action. Both extrusion and vibration loosen effects were achieved during the process, which the soil mattress were loosened by the cutting, bending and stretching force. The direction of the excitation and the cutting blade had a certain angle, which helped to reduce the traction resistance and had a better effect on the soil loosen.
