Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1-4, the present invention provides a mower blade guard structure, which includes: a tray 10, ribs 20 and a blade 30.

The tray body 10 is provided with fixing holes 11 and connecting holes 12, the connecting holes 12 are located in the center of the tray body 10, the connecting holes 12 are used for connecting a driving shaft, the fixing holes 11 are arranged on the periphery of the tray body 10, and the fixing holes 11 are arranged at intervals along the circumferential direction of the tray body 10.

The reinforcing ribs 20 are fixedly arranged on the disc body 10, and the reinforcing ribs 20 are welded and fixed on the cutter head. The reinforcing ribs 20 are respectively arranged corresponding to the fixing holes 11, each reinforcing rib 20 comprises a first flanging 21, a second flanging 22, a first folding edge 23 and a second folding edge 24, and the first flanging 21, the second flanging 22, the first folding edge 23 and the second folding edge 24 are formed in an integrated forming mode.

The first flanging 21 and the second flanging 22 are attached to the surface of the tray body 10, the first folding edge 23 is connected with the second folding edge 24, the first folding edge 23 and the second folding edge 24 protrude out of the surface of the tray body 10, an included angle is formed between the first folding edge 23 and the second folding edge 24, and the included angle range is 0-180.
