摘要： A soil aeration device may include a plurality of arcuate blades mounted to an assembly adapted to rotate and translate the blades proximate a ground surface, thereby forming aeration pockets in the soil. In certain embodiments, the arcuate tines penetrate and fracture the soil while minimizing the amount of soil lifted from the pocket deposited on the top of the soil. In various embodiments, a planetary gear assembly imparts to the tine a translational and rotational movement which creates a fractured pocket in the soil while minimizing the amount of soil lifted from the pocket and deposited on the surface of the soil. In still other embodiments, the arcuate tine may have mounted thereon a coring tube that cuts and removes a plug from the pocket formed in the soil.

摘要： A soil aeration apparatus may include aeration tines that are actuated by a relatively compact gear system that reduces the size and weight of the apparatus. In addition, a soil aeration apparatus may operate without a centrally disposed support shaft, thus enabling the tine-holder shafts to be positioned closer to one another and reducing the size of the apparatus.

摘要翻译： 土壤曝气装置可以包括由相对紧凑的齿轮系统致动的曝气齿，其减小了装置的尺寸和重量。 此外，土壤曝气装置可以在没有中心设置的支撑轴的情况下操作，从而使得叉架轴能够彼此更靠近并且减小装置的尺寸。

摘要： In certain embodiments a soil aerator may include a hinged frame assembly that cooperates with one or more weight transferring systems adapted to permit an aeration subassembly to lift off the ground when an aeration tine impacts a hard obstacle such as a rock in the soil. The weight transferring systems may in the preferred embodiments be calibrated so that only minimal upward force, such as that caused by impact of an aeration tine with a rock, may cause the aeration subassembly to lift thereby significantly reducing or preventing damage to the aeration tines and drive assemblies and substantially prolonging the life of the aerator.

摘要翻译： 在某些实施例中，土壤充气器可以包括铰接框架组件，该铰接框架组件与一个或多个重量传递系统配合，该系统适于允许曝气组件在曝气尖撞击诸如土壤中的岩石的硬障碍物时离开地面。 在优选实施例中，重量传递系统可以被校准，使得只有最小的向上的力，例如由曝气叉与岩石的冲击引起的向上的力可能导致通气组件升高，从而显着地减少或防止对曝气叉的损坏， 驱动组件并显着延长曝气器的使用寿命。
