During the mulching process, the two No. 2 compression springs 33 press the pressure roller 34 down, and at the same time the pressure roller 34 presses the film to adhere to the surface of the soil.

[0025] Please see Figures 1-3As shown, fixing components 2 are provided on the same side of both mounting plates 1. Each fixing component 2 includes a support plate 21, which is fixedly connected to the mounting plate 1. A conveying component 22 is provided on the side of the support plate 21 away from the mounting plate 1. The conveying component 22 includes a first slider 221, which is slidably disposed on one side of the support plate 21. A first compression spring 222 is fixedly disposed on the upper side of the first slider 221, and the upper side of the first compression spring 222 is fixedly connected to the top of the support plate 21. A scraper 223 is slidably disposed on the side of the support plate 21 away from the first slider 221. A slot matching the rotating shaft of the scraper 223 is provided on one side of the support plate 21. A motor 224 is fixedly installed on one side of the support plate 21. The shaft of the motor 224 is fixedly connected to the shaft of the scraper 223. When the mulching machine is started, the user starts the motor 224 to drive the scraper 223 to rotate. Under the pressure of the first compression spring 222, the scraper 223 is always in contact with the ground. At the same time, the scraper 223 lifts the soil upward. A guide component 23 is provided on the side of the support plate 21 near the conveying component 22. The guide component 23 includes a collecting plate 231. One end of the collecting plate 231 is slidably connected to one side of the support plate 21. A connecting rod 232 is symmetrically fixed between the collecting plate 231 and the first slider 221. The connecting rod 232 is slidably disposed on one side of the support plate 21. While the first compression spring 222 presses the scraper 223 downward, the collecting plate 231 slides downward with the scraper 223. A first guide plate 233 is fixedly installed on the lower side of the collecting plate 231, and the first guide plate 233 is inclined towards the side closer to the scraper 223.

The user adjusts the position of the second slider 235 according to the position of the film edge. After adjusting the second slider 235 to above the edge of the film, the user tightens the screw 236 to fix the second slider 235. The soil raised by the scraper 223 falls to the upper side of the second guide plate 234. Then the soil falls along the first guide plate 233 and the second slider 235 to the edge of the film and fixes the film.

[0026] In this embodiment, the anti-blowing device during film covering is first installed on the underside of the film covering machine. Then, the user passes the film through the underside of the pressure roller 34 and fixes one end of the film in the soil. Under the pressure of the two second-order pressure springs 33, the pressure roller 34 presses the film into contact with the soil surface. Then, the user starts the motor 224 to drive the scraper 223 to rotate. The scraper 223 lifts the soil and transports it to the upper side of the second-order guide plate 234. The soil falls along the second-order guide plate 234 and the first-order guide plate 233 to the edge of the film and fix the film. During the film covering process, the device automatically presses the film into contact with the soil and transports the surrounding soil to both ends of the film to fix the film.
