Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples:

as shown in fig. 1-3, a blade disc drive structure of lawn mower, including dead lever 1, the cover has assembly cover 7 that can rotate on the dead lever 1, 7 outer wall departments of assembly cover are provided with rolling disc 4, 1 lower extreme of dead lever is provided with carries out the limiting plate 2 that the axial supported to assembly cover 7, rolling disc 4, be provided with a plurality of cutting blade 5 on the rolling disc 4, rolling disc 4 is visited to cutting blade 5's front end.

The fixed rod 1 is further sleeved with a gasket 3, one end of the gasket 3 is in contact with the rotating disc 4, and the other end of the gasket 3 is in contact with the limiting plate 2.

A bearing 8 and a bearing 9 II are arranged in the assembling sleeve 7, and the fixing rod 1 is fixed with the inner rings of the bearing 8 and the bearing 9 II.

And a driving assembly for driving the assembling set 7 to rotate is arranged on the outer wall of the assembling set.

The driving assembly comprises a driven gear 10 arranged on the outer wall of the assembling sleeve 7, and the driven gear 10 is meshed with a driving gear 13 on a main shaft of a driving motor 12.

The driving motor 12 and the fixing rod 1 are both arranged and fixed with the frame of the mower.

A plurality of ribbed plates 11 for reinforcement are arranged between the assembling sleeve 7 and the rotating disc 4.
