[0001] The present application relates to the technical field of lawn mowing robot equipment, and in particular to a lawn mowing robot blade protection structure and a lawn mowing robot. Background Art

[0002] A lawn mower robot is a widely used gardening weeding equipment, also known as a weeding robot or a lawn mowing robot. The lawn mower robot is used to mow lawns and vegetation. The main components include a cutter disc, a blade, a drive device, a running wheel, a running mechanism, and a control system. The blade rotates at high speed under the drive device to cut the lawn or vegetation, saving labor costs and manual operation time, and improving weeding efficiency. It is widely used in lawn mowing and maintenance in green spaces, golf courses, etc. During the movement of the lawn mower robot, the cutter disc and the blade are easily affected by various factors such as uneven terrain and stone obstacles on the ground, and may be stuck or damaged during the mowing process. Therefore, a blade protection mechanism is usually required to be set around the blade to protect the cutter disc and the blade. Usually, the blade protection structure is provided with a comb-tooth structure. Through the comb-tooth structure, while filtering obstacles, the grass can be moved to the inside of the cutter disc protection structure to contact the blade to complete the mowing. However, the comb-tooth structure usually adopts a suspended installation method, and the comb-tooth structure itself is suspended on the blade protection structure, which causes the comb teeth to be easily bent or broken when encountering uneven terrain and stone obstacles on the ground. In addition, the tip of the open comb teeth is easy to get caught on the rope, increasing the risk of the lawn mower robot being entangled in the rope. Summary of the invention

[0003] Based on this, it is necessary to provide a lawn mower robot blade protection structure and a lawn mower robot to address the problem that the comb teeth of the blade protection structure of the lawn mower robot are easy to bend and break and have a high risk of entanglement.
