[0001] The utility model relates to the technical field of ground film recovery tools, in particular to a ground film recovery device for tobacco fields. Background Art

[0002] In tobacco production, mulch films are used to maintain moisture and heat during cultivation. Since the research, demonstration, and promotion of mulch film cultivation in the 1980s, the area of ​​tobacco cultivation has steadily expanded and is now an essential technology for producing high-quality tobacco leaves. However, the mulch films currently in common use are primarily composed of polyethylene, which is difficult to degrade under natural conditions. To avoid soil contamination, the tobacco leaves must be promptly recycled and disposed of after harvest.

[0003] Tobacco is mostly grown in mountainous areas, and currently, artificial mulch is mostly used. One or two people are needed to pick up one end of the mulch and roll the mulch ball to the other end. This is labor-intensive, with low efficiency in removing the mulch and requiring long periods of bending over to operate, which is time-consuming and labor-intensive. Commonly used mulch film recycling machines are large in size and difficult to adapt to small and scattered mountainous areas, and are not flexible enough to operate.

[0004] Therefore, the utility model provides a ground film recovery device that is simple and convenient to operate. Utility Model Content

[0029] Example 1

[0030] like Figure 1-5The device, shown in Figure 1, includes a support frame 1 with an inverted U-shaped structure. A handle 2 is attached to the top of the support frame 1. The handle 2 can be provided with a non-slip pad for easy gripping. The handle 2 is connected to the support frame 1 via two connecting rods 3. The angle between the connecting rods 3 and the support frame 1 is 120-150 degrees, making it easy for workers to pull the support frame 1 with the handle 2 to achieve mulch film recovery.

[0031] The bottom ends of the support frame 1 are rotatably connected to a film roll assembly. This assembly comprises several rollers connected in series, each radially provided with a plurality of film roll teeth 11. The ends of the rollers away from the rollers are conical, and the length of the teeth 11 is 8-12 mm. This structure allows the teeth 11 to easily penetrate and lift the ground film, eliminating the difficulty of retracting the film due to a short length and the increased resistance due to an excessive length.

[0032] The rollers include a symmetrically arranged first roller 4, a second roller 5, and a third roller 6. A rotating shaft 10 is arranged at both ends of the support frame 1. One end of the rotating shaft 10 is fixedly connected to the support frame 1, and the other end is rotatably connected to one end of the first roller 4. The other end of the first roller 4 is rotatably connected to the second roller 5 via a first connecting member 7, and the two second rollers 5 are rotatably connected to the third roller 5 via a second connecting member 8. The first roller 4 and the third roller 5 are both arranged horizontally. The angle between the axis of the first roller 4 and the adjacent second roller 5 is 45-60°. The use of the first roller 4, the second roller 5, and the third roller 5 in combination can better fit the tobacco field ridges and facilitate the winding and recycling of the ground film.

[0033] A limiting ring 9 is provided inside both ends of the roller. The limiting ring 9 can slide along the inner wall of the roller. A bearing 13 is provided between both ends of the roller and the limiting ring 9. The roller and the limiting ring 9 can rotate freely. Two support rings are provided on the inner wall of the roller corresponding to each bearing 13. The bearing 13 is embedded between the support rings, which can limit the bearing 13 to prevent it from falling out of the roller. The outer wall of the limiting ring 9 is provided with a stepped protrusion, which can abut the outermost support plate 12 to limit the position of the roller. The other end of the limiting ring 9 is detachably connected to the rotating shaft 10, the first connecting member 7 or the second connecting member 8. The limiting ring 9 can be mounted on the outside of the rotating shaft 10, the first connecting member 7 or the second connecting member 8, and the side wall of the limiting ring 9 is provided with a through hole 14, through which a bolt can pass to connect to the rotating shaft 10, the first connecting member 7 or the second connecting member 8.

[0034] Installation process:

[0035] Sleeve the limiting ring 9 on the rotating shaft 10 and fix it with the rotating shaft 10 through bolts. Sleeve one end of the first roller 4 on the outside of the limiting ring 9 so that the first roller 4 is rotatably connected to the limiting ring 9. Then, fix the limiting rings 9 at both ends of the first connecting member 7. Insert the limiting rings 9 into the first roller 4 and the second roller 5 respectively. Then connect the limiting ring 9 at one end of the second connecting member 8, insert the limiting ring 9 into the inside of the second roller 5, sleeve the limiting ring 9 on the other end of the second connecting member 8, place the third roller 5 in the target position, and then slide the limiting ring 9 until the outer wall of the limiting ring 9 bulges against the outer support plate 12 of the third roller 5. At this time, rotate the limiting ring 9 so that the bolts are inserted into the through holes 14 and threadedly connected to the second connecting member 8. The installation is now complete.

[0036] Usage process:

[0037] During use, the film rolling assembly is placed on the ridge, the first roller 4 is close to the interval between the ridges, the second roller 5 is close to the side wall of the ridge, and the third roller 5 is at the top of the ridge. The film rolling teeth 11 on the surface of the roller can be inserted into the ground film. Then the staff pulls the support frame 1 through the handle 2, and the first roller 4, the second roller 5 and the third roller 5 all move along the surface of the ridge. The ground film is wound on the surface of the roller with the cooperation of the film rolling teeth 11 and the rotation of the roller. The operation is simple and convenient, and the recycling efficiency is high.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
