[0002] Ground film has the functions of increasing ground temperature, inhibiting surface water evaporation, inhibiting weeds, inhibiting salt and protecting seedlings, increasing the uniformity of crop canopy illumination and increasing scattered light. It has become the fourth most important material for agricultural production after seeds, fertilizers and pesticides. The application of ground film covering technology has also significantly improved agricultural productivity. However, its material is polyethylene (PE). While the ground film covering the field effectively promotes crop growth, if it is not cleaned up in time, the PE ground film will remain in the soil and will be difficult to degrade, which will cause pollution and damage to the soil, which is not conducive to maintaining soil structure and the growth of later crops. Therefore, the ground film needs to be recycled, and the ground film recycling machine is a mechanical equipment specially used to recycle the residual ground film in farmland. When using a mulch film recycling machine to recycle mulch film, the rolled up mulch film often carries a large amount of soil, root stubble, stones and other impurities, resulting in a large amount of debris between the mulch rolls that are finally rolled up, affecting recycling and use. Therefore, we have proposed a farmland mulch film recycling machine that can effectively separate the mulch stubble. Summary of the invention

The V-shaped thin plate 116 is pulled by the electric push rod 115 to move in the direction of the adjusting mechanism 112. When the V-shaped thin plate 116 moves in the direction of the adjusting mechanism 112, the soil, stones and other debris accumulated on the inner side of the V-shaped scraper 111 are scraped and discharged. The V-shaped thin plate 116 is close to the When the ground film 14 is recovered, the screening holes 117 on the surface are intermittently inserted into the contact with the root stubble and other thin strips of debris on the surface of the recovered ground film 14. By opening a plurality of screening holes 117 on the surface of the V-shaped thin plate 116, the root stubble and other thin strips of debris on the recovered ground film 14 are stripped and screened. When the inner side surface of the recovered ground film 14 is not in tight contact with the side surface of the V-shaped scraper 111, the distance between the V-shaped scraper 111 and the inner side surface of the recovered ground film 14 is adjusted by the adjustment mechanism 112. When the position of the V-shaped scraper 111 needs to be adjusted, the cross block 1121 is twisted to drive the threaded rod 1122 on one side to rotate. When the threaded rod 1122 rotates, it moves in threaded cooperation with the internal threaded cylinder 1123. The cross block 1121 is twisted to drive the threaded rod 1122 to The threaded fit of the internal threaded barrel 1123 is used to adjust the distance between the V-shaped scraper 111 and the inner side of the recovered ground film 14. When the cross block 1121 rotates, the threaded rod 1122 and the threaded fit of the internal threaded barrel 1123 rotate and move together with the threaded rod 1122. When the cross block 1121 moves, it drives the docking ring block 1125 and the vertical rod 1126 on one side to move together. When the docking ring block 1125 moves, it drives the corrugated ring piece 1124 on one side to stretch or contract. By arranging a corrugated ring piece 1124 that cooperates with the stretching or contraction on the outside of the threaded rod 1122 to wrap and cover the outside of the threaded rod 1122, the corrugated ring piece 1124 is driven to stretch or contract by the rotational connection between the docking ring block 1125 and the cross block 1121.The vertical rod 1126 that rotates together with the cross circle 1121 drives the side brush 1127 on the outer surface to rotate together. The side brush 1127 rubs and cleans the outer surface of the corrugated ring piece 1124 as the vertical rod 1126 rotates. The square pressing plate 123 is pushed downward by the electric push rod 122. When the square pressing plate 123 moves downward, it pushes the square sponge pad 124 at the bottom to move downward together. When the square sponge pad 124 moves down and contacts the recycled ground film 14 on the surface of the linkage roller 9, it is continuously squeezed and compressed by the square pressing plate 123. A flexible square sponge pad 124 is provided between the square pressing plate 123 and the recycled ground film 14 to press the recycled ground film 14. When the square sponge pad 124 is squeezed, the inner The square pressing plate 123 compresses the return spring 127, and the gradually downwardly moving square pressing plate 123 and the thin through rod 128 penetrating the square pressing plate 123 are relatively displaced. The square sponge pad 124 is fixed and limited by arranging the thin through rod 128 penetrating the square pressing plate 123 on the circular gasket 126. The circular gasket 126 is elastically spaced between the square sponge pad 124 and the thin through rod 128. When the recycled ground film 14 is not required to be flexibly pressed, the square pressing plate 123 is driven upward by the electric push rod 122. At this time, the return spring 127 loses the pressure of the square pressing plate 123. The return spring 127 that loses the pressure drives the square sponge pad 124 to expand and recover through the extension force.
