Rolling lawn aerator

A rolling lawn aerator, comprising a perforating device, wherein the perforating device is capable of rolling on a lawn so as to perforate and aerate soil under the lawn;

• the perforating device comprises a body assembly and a plurality of perforating assemblies, and the plurality of perforating assemblies are arranged in a circumferential direction of the body assembly;
• each of the perforating assemblies comprises:
• a perforating pipe, wherein the perforating pipe is rotationally connected to the body assembly, and under the condition of no external force, an extension direction of the perforating pipe does not coincide with a radial direction of the body assembly;
• and
• a limiting member, wherein the limiting member comprises an elastic member, and the elastic member is connected to the body assembly and the perforating pipe;
• and
• when the perforating device rolls in a first direction to perform a perforating operation, each of the elastic members is configured to be connected to the respective perforating pipe in contact with the ground of the lawn and is capable of limiting rotation of the perforating pipe with the body assembly, so that the perforating pipe is inserted into the soil under the lawn at an approximately vertical angle and pulled out of the soil at an approximately vertical angle;
• and
• wherein each of the perforating pipes comprises a first end portion, a second end portion and a connection portion, the first end portion and the second end portion are respectively located on two sides of the connection portion, the first end portion is connected to the respective elastic member, and the connection portion is rotationally connected to the body assembly.
