[0019] like Figures 1-5 As shown, the protective cover of this utility model stubble pruning and soil loosening device includes a cover shell 1 with a cross-section nearly half-circular and reinforced with ribs 11 on the upper edge, and retaining steel plates on both sides of the cover shell 1. Two cantilever connecting plates 2 are symmetrically welded at the arc apex of the outer surface of the cover shell 1, and the cantilever connecting plates 2 are connected together to the long slender diameter shaft of the secondary rotation output borrow shaft. A bushing 2 of the long slender diameter shaft is welded on the left cantilever connecting plate 2 corresponding to the fixing hole of the long slender diameter shaft. . 1. A lifting rocker arm 3 is welded to the left side of the bushing 2.1. The lifting rocker arm 3 is integrated with the stubble tamping and loosening device housing 1 via the bushing 2.1 and the left cantilever connecting plate 2. A large retaining steel plate 4 is welded to the left end of the housing 1, and a small retaining steel plate 5 is welded to the right end. A left ear plate 4.1 is provided on the lower front end of the large retaining steel plate 4 on one side of the outer arc surface of the housing 1, and a left mounting hole a is provided on the left ear plate 4.1. A right ear plate 5.1 is provided on the lower front end of the small retaining steel plate 5 on one side of the outer arc surface of the housing 1, and a right mounting hole b is provided on the right ear plate 5.1. The left mounting hole a and the right mounting hole b are coaxial and share a smooth rod 6. A ground pressing wheel 7 is suspended on the smooth rod 6. A lifting ring 8 for rotating the housing 1 is provided on the upper part of the arc outer surface of the housing 1. The lifting ring 8 and the lifting rocker arm 3 are on the same straight line at their structural action points on the housing 1.

[0020] like Figure 2 As shown, the large retaining steel plate 4 has a shaft insertion hole c for the moving shaft structure of the stubble tiller at the bottom, and a shaft insertion hole d for the secondary rotation output shaft at the top. The large retaining steel plate 4 has several mounting holes 4.2 around its perimeter that match the flange shape of the multi-functional cover box, forming a large flange. The large flange is connected to and fixed to the flange of the multi-functional cover box via the mounting holes 4.2 and bolts. An anti-winding cover 5.2 is welded to the inner arc surface of the cover 1 on the inner wall of the small retaining steel plate 5. The small retaining steel plate 5 has a semi-circular hole e for installing the fixed shaft of the stubble tiller at the bottom of its rear vertical wall.
