AI Technical Summary
Technical Problem
The blade of the lawn mower is prone to break when it encounters hard objects such as stones, resulting in unstable use of the equipment and frequent maintenance.
Method used
By controlling the hardness on the blade body, it is kept within the 5-45 HRC range under high walking speed and linear speed conditions, while increasing the hardness of the cutting part to enhance wear resistance.
Benefits of technology
It effectively reduces the risk of blade fracture, improves the equipment's use stability and maintenance cycle, and meets the needs of high cutting efficiency and wear resistance.

Abstract
The present disclosure provides a mower. The mower comprises: a mower body; a moving module for driving the mower to move; and a cutter head, wherein the cutter head is provided with at least one blade, the cutter head is driven by a cutting motor to rotate so as to drive the blade to rotate, and the blade comprises a blade body adapted to be connected to the cutter head and a cutting part connected to the blade body and used for executing mowing operation; and when the locomotion speed is greater than or equal to 1 m / s and the linear speed of the blade is greater than or equal to 30 m / s and less than or equal to 70 m / s, the hardness value range of the blade body is 5-45 HRC. According to the mower, on the premise of increasing the locomotion speed and the linear speed and ensuring that the thickness of the blade cannot be too thick and the extending length of the blade cannot be too small, the risk of blade breakage is reduced by reducing the hardness of the blade body.
