Perforator for lawn aerator and lawn aerator having same

Abstract

Disclosed are a perforator and a lawn aerator. The perforator includes a main portion and a plurality of perforating portions. The main portion is in a disk shape, and the plurality of perforating portions are integrally formed with the main portion. The plurality of perforating portions extend radially outward from an outer periphery of the main portion, and arranged at intervals in a circumferential direction. Each perforating portion is recessed in an axial direction, so that two opposite surfaces of the perforating portion in the axial direction are respectively a first concave surface and a first convex surface. According to this configuration, both a relatively high density of the aeration holes and a relatively large aeration hole size can be obtained. In addition, the first concave surface and the first convex surface can help to strengthen the perforating portion, thereby preventing the perforating portion from deforming.
