[0036] The working principle of the above embodiments is as follows:

[0037] Push the mounting rod 18 so that it is positioned between the two punching wheel frames 13. Rotate the rotating plate 19, which drives the second screw 16 to rotate. Through the threaded connection between the second screw 16 and the mounting rod 18, the mounting rod 18 is fixed to the punching wheel frame 13. Push the punching wheel 11 so that it slides on the mounting rod 18, thereby adjusting the distance between two adjacent punching wheels 11. Rotate the drive rod 24, which, through the threaded connection between the drive rod 24 and the first screw 23, and the connection between the positioning plate 26 and the positioning groove 27, ... The sliding connection between the two causes the first screw 23 to move the sliding rod 22 downward through the moving plate 25. The sliding rod 22 is inserted into the interior of the sliding groove 20. Through the fit between the rubber ring 21 and the sliding groove 20, the perforating wheel 11 is fixed on the mounting rod 18. Pulling the adjuster 3 causes the perforating wheel frame 13 to flip downward through the action of the first hinge frame 2 and the second hinge frame 4, so that the perforating rod 10 is inserted into the interior of the soil. The mulching machine frame 1 drives the perforating wheel frame 13 to move, so that the perforating wheel 11 rotates, thereby perforating the mulch film.
