Kind Code:
A1
Abstract:
A cutting mechanism, and a lawn mower (90). The cutting mechanism comprises a driving apparatus (200), and a cutting apparatus (100) connected to the driving apparatus (200). The cutting apparatus (100) is configured to execute a cutting task under the driving of the driving apparatus (200), the cutting apparatus (100) comprises a plurality of cutting units (101, 102, 103, 104, 105) stacked along a first direction A1, each cutting unit (101, 102, 103, 104, 105) comprises at least one cutting element (1011, 1021, 1031, 1041, 1051), and each cutting unit (101, 102, 103, 104, 105) forms a cutting area when the cutting task is executed. On at least one second direction A2 perpendicular to the first direction A1, a first preset distance S1 is provided between edges of the cutting areas of the two cutting units (101, 102, 103, 104, 105) closest to a working surface, the first preset distance S1 satisfies aa, and the edge of the cutting area of the cutting unit (101, 102, 103, 104, 105) closest to the working surface is closer to the driving apparatus (200) on the second direction A2. V represents the moving speed of the cutting apparatus (100) when executing the cutting task, n represents the rotating speed of the cutting apparatus (100) when executing the cutting task, and N2 represents the number of cutting elements (1011, 1021, 1031, 1041, 1051) in each cutting unit (101, 102, 103, 104, 105).
