By mounting a plurality of anti-tangling plates 3 on the blade sets 2 and a plurality of weed-chopping mechanisms 4 on the anti-tangling plates 3, weeds contacted by the anti-tangling plates 3 can be cut during rotary tillage, preventing weeds from tangling onto the anti-tangling plates 3. The sequential and intervally arranged weed-chopping mechanisms 4 on the anti-tangling plates 3 along the axial direction improve the anti-tangling effect of the anti-tangling plates 3.
[0036] The anti-winding plate 3 is a toothed plate 33. By making the anti-winding plate 3 a toothed plate 33, the strength of the anti-winding plate 3 can be improved, and the anti-winding effect of the anti-winding plate 3 can be improved.

By having a plurality of bent triangular teeth 332 spaced apart on the flat plate 331, and by having the grass-chopping mechanism 4 disposed on the ridge of the bent triangular teeth 332 and / or on the flat plate 331, the strength of the anti-tangling plate 3 can be improved, and the grass can be cut by the anti-tangling plate 3, preventing the grass from getting tangled on the anti-tangling plate 3.
[0038] The cutter barrel 1 is provided with several support plates 5, which are set on the shredding blade groups 2 at both ends of the cutter barrel 1 or on adjacent shredding blade groups 2.

[0039] The support plate 5 is one or more of a circular plate, a triangular plate, and a toothed circular plate; the teeth of the toothed circular plate face the same direction as the cutting portion 42 of the chopped grass. The support plate 5, being one or more of a circular plate, a triangular plate, or a toothed circular plate, provides stable support for the crushing device. The fact that the teeth of the toothed circular plate face the same direction as the cutting portion 42 of the chopped grass facilitates rotary tillage by the crushing device.
[0040] Crawling blocks 6 are provided on the support plates 5 at both ends of the cutter cylinder 1. The crawling blocks 6 are L-shaped plates.
