[0029] See also Figures 1 to 6 As shown, a crop sowing film covering device includes a film covering device body, which is a model commonly used in existing crop sowing. The film covering device body includes a shell 1, a push rod 2 is installed on the rear side of the shell 1, and first connecting frames 3 are symmetrically installed on the left and right side walls of the shell 1. The bottom ends of the outer walls of the two first connecting frames 3 are rotatably connected with traveling wheels 4 through bearings. When the push rod 2 is driven to move, it can drive the shell 1 and the traveling wheel 4 to move backward.

The reeling component includes a film roll 11, and the guide and limiting component includes a guide roller 16 and a wheel body 20. The film roll 11, the guide roller 16 and the wheel body 20 are sequentially arranged in a downward trend from back to front to ensure that the film extended from the film roll 11 can pass through the guide roller 16 and the wheel body 20 in sequence to achieve directional guidance and limitation before laying. The film extended from the outer wall of the film roll 11 extends to the front side via the lower surface of the guide roller 16 and is limited under the action of the wheel body 20.

[0030] See also Figure 1 and Figure 2As shown, the unwinding assembly includes a connecting seat 5 installed at the bottom end of the outer wall of the shell 1, and the second connecting frame 6 is symmetrically installed on the left and right side walls of the connecting seat 5. A supporting seat 7 is vertically installed on the front side of the second connecting frame 6. A placement groove 8 is opened on the top of the outer wall of the supporting seat 7. A baffle 9 perpendicular to the inner wall of the placement groove 8 is installed on the top of the placement groove 8.

The film extended from the film roll 11 can be limited by the guide roller 16, and the rotatable guide wheel 16 can reduce the friction force on the film, so that the film can be laid more smoothly; the guide and limiting component also includes a cylinder 17 installed at the top end of the top plate 13, the output end of the cylinder 17 downwardly penetrates the outer wall of the top plate 13 and is connected to a top frame 18, and the left and right sides of the bottom end of the outer wall of the top frame 18 Two fourth connecting frames 19 are vertically installed on both sides, and the wheel body 20 is rotatably connected to the bottom end of the fourth connecting frame 19. As the equipment moves toward the rear side, the film is laid along the lower surface of the guide roller 16 and the bottom end of the wheel body 20. At this time, the guide roller 16 performs the first limiting guidance on the film extending from the outer wall of the film roll 11, and at the same time, with the help of the guiding effect of the wheel body 20, the film at the guide roller 16 is laid flat into the ridge; in order to ensure that the top frame 18 can move in the vertical direction, a limiting rod 21 is provided through the outer wall of the top plate 13 to move up and down, and the limiting rod 21 is connected to the top end of the outer wall of the top frame 18. When the top frame 18 moves, the limiting rod 21 can be driven to move up and down along the outer wall of the top plate 13 to limit the movement of the top frame 18;

[0033] The film extended from the film roll 11 is extended to the front side through the lower surface of the guide roller 16, and the two side edges of the film are pressed against the bottom ends of the two wheel bodies 20 respectively, and the free end of the film is first fixed in the ground with the help of soil.

As the equipment continues to move, the fifth connecting frame 22 drives the soil-building plate 24 to suddenly bury the ridge at the edge of the film, so as to achieve the laying and soil-building of the side of the film at the ridge, and the outer wall of the fifth connecting frame 22 is installed with a fixed seat 26, the outer wall of the fixed seat 26 is rotatably connected to a worm 27 through a bearing, and the worm 27 is meshed with the outer wall of the worm wheel 25. By driving the worm 27 to rotate, the worm wheel 25 is prompted to be adjusted circumferentially, thereby realizing that the connecting shaft 23 drives the soil-building plate 24 to adjust the inclination angle, so as to enable soil-building plates 24 with different inclination angles to achieve the soil-building requirements of ridges of different widths.

[0035] See also Figure 1 and Figure 6 As shown, the plowing assembly includes a sixth connecting frame 28 respectively installed on the left and right side walls of the shell 1, and two plowing wheels 29 are symmetrically arranged at the bottom end of the outer wall of the sixth connecting frame 28, and the two plowing wheels 29 are arranged with a contraction trend from front to back.
