In the present embodiment, the blade 5 can rotate 360 degrees on the blade shaft 6.

The second embodiment is as follows: the embodiment is described with reference to fig. 1 and fig. 2, each grass blocking assembly of the crusher crushing rotor in the embodiment includes a grass blocking ring 6 and a plurality of connecting plates 7, the grass blocking ring 6 is an annular body formed by sequentially connecting a plurality of arc segments 6-1 end to end, and two adjacent arc segments 6-1 are connected through the connecting plates 7. Other components and connections are the same as those in the first embodiment.

The third concrete implementation mode: the embodiment is described with reference to fig. 1 and fig. 2, each connecting plate 7 of the crushing rotor of the crusher according to the embodiment is provided with two strip-shaped holes 7-1 arranged in a V shape, and the end parts of two adjacent arc segments 6-1 are respectively inserted into the two strip-shaped holes 7-1.

When in use, the position of the arc section 6-1 in the strip-shaped long hole 7-1 can be adjusted according to actual needs, so that the outer diameter of the grass blocking ring 6 can be adjusted.

Other components and connection relationships are the same as those in the second embodiment.

The fourth concrete implementation mode: the embodiment is described with reference to fig. 1 and 2, and the crushing rotor of the crusher further comprises a plurality of pawls 8, and each circular arc segment 6-1 is provided with one pawl 8.
