Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0030] This patent provides a variety of parallel solutions. The different expressions are improved solutions or parallel solutions based on the basic solution. Each solution has its own unique characteristics. In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other. The fixing method not described in the text can be any fixing method such as thread fixing, bolt fixing or glue bonding.

[0031] Embodiment 1: In combination with all the accompanying drawings; a gravity laminating machine with adjustable width, characterized in that:

[0032] The gravity laminating machine comprises two sets of symmetrically arranged special wheels, wherein the special wheels comprise an integrated gravity wheel body 4 and a film pressing part 5, wherein the film pressing part 5 is a circular sheet structure having a diameter larger than that of the gravity wheel body 4;

[0033] The film pressing part 5 can press the ground film, and the film pressing part 5 can press the edge of the ground film into the soil. The substantial technical effect and the realization process of the technical solution here, that is, the basic function are as follows: the ground film can be pressed tightly by using two sets of symmetrically arranged special wheels.

[0034] Double wheels refer to double special wheels: the special wheel consists of two parts, one is the film pressing wheel, and the other is the gravity wheel; the film pressing wheel is a thin sheet, and the gravity wheel has a certain thickness.

[0035] The gravity wheel has two functions. One is to increase weight. Due to the gravity, the film pressing wheel presses the ground film into the soil. Because the film pressing wheel is a thin sheet, it will automatically press into the soil due to gravity, omitting the covering process of conventional film covering machines. Although the film pressing wheel is a thin sheet, it will not damage or scratch the ground film due to the ductility of the ground film. The second is to limit the position. The diameter of the film pressing wheel and the gravity wheel is different. The diameter difference between the two wheels can control the depth of the ground film pressed into the soil by about three centimeters.

[0036] Embodiment 2: As a further improved solution or parallel solution or optional independent solution, the distance between the two sets of symmetrically arranged special wheels can be adjusted. The substantial technical effect and implementation process of the technical solution here, i.e. the basic function, are as follows: it can be adjusted to meet different laminating width requirements.

[0037] Embodiment 3: As a further improved solution or a parallel solution or an optional independent solution, the special wheel is passed through by a threaded rod 6, one side of the threaded rod 6 is threadedly installed in the functional wheel sleeve 3, and rotating the threaded rod 6 can relatively adjust the distance between the two special wheels to adapt to different widths of ground membranes. The substantial technical effect of the technical solution here and its implementation process, that is, the basic function, are as follows: rotation can adjust the width. A specific way to adjust the width is provided, and similar implementation methods are within the scope of protection of this patent. The rod between the two wheels is hollow, and its main function is reinforcement. The width between the two wheels can be adjusted to meet the needs of ground membranes of different widths.

[0038] The clamping point for installing the mulch film also has a limiting function and can be adjusted in height. For example, if there is no time to cover the film during the busy farming season, this mulching machine can also be used for covering the film when the seedlings have all grown out, and it will not damage the roots of the seedlings. The mulch film in bundles can be placed in a higher position to improve the installation position of the mulch film in bundles, and the width between the double wheels can be adjusted according to the spacing between the seedlings, so that covering the film will not damage the roots of the seedlings.

[0039] The width can be adjusted by installing the screw rod just above the ground film. This width adjustment is consistent with the width adjustment between the double wheels.

[0040] Embodiment 4: As a further improved solution or parallel solution or optional independent solution, the threaded rod 6 is connected to the support part 1 through the connecting plate 17, and the side fixing plate 15 is welded on the support part 1, and the side fixing plate 15 is arranged with a mounting groove 16, and the mounting groove 16 includes a mounting groove outlet 13, and also includes a film wheel shaft 9 that can overlap the two mounting grooves 16, and the film wheel shaft 9 passes through the central part of the ground film roll. The substantial technical effect and implementation process of the technical solution here, that is, the basic function, are as follows: The structure is used to replace the ground film.

[0041] Embodiment 5: As a further improved solution or parallel solution or optional independent solution, a position plate 12 is arranged on the support part 1, and a side fixing block 11 is fixed on the position plate 12. The side fixing block 11 is arranged with a threaded hole for passing the connecting rod 10, and the two sides of the connecting rod 10 are fixed by nuts. The substantial technical effect and implementation process of the technical solution here, that is, the basic function, are as follows: used to maintain the stability of the bracket.

[0042] Embodiment 6: As a further improved solution or parallel solution or optional independent solution, the two sides of the two sets of symmetrically arranged special wheels each include a fixing plate 7. The substantial technical effect and implementation process of the technical solution here, i.e. the basic function, are as follows: used to relatively fix the wheels.

[0043] Embodiment 7: As a further improved solution or parallel solution or optional independent solution, the end of the support part 1 is connected to the handheld part 2. The substantial technical effect and implementation process of the technical solution here, i.e. the basic function, are as follows: used to lift and push the trolley forward.

[0044] Embodiment 8: As a further improved solution or parallel solution or optional independent solution, the gravity wheel body 4 is made of metal. The substantial technical effect and implementation process of the technical solution here, i.e., the basic function, are as follows: Similar materials are within the protection scope of this patent.

[0045] Embodiment 9: As a further improved solution or parallel solution or optional independent solution, a special wheel is characterized in that the special wheel comprises an integrated gravity wheel body 4 and a film pressing part 5, and the film pressing part 5 is a circular sheet structure with a diameter larger than the gravity wheel body 4. The structure is an individual that can be sold and used separately.

[0046] Innovatively, each of the above effects exists independently, and a set of structures can be used to combine the above results.

[0047] It should be noted that the multiple solutions provided by this patent include the basic solution itself, which are independent of each other and do not restrict each other, but they can also be combined with each other without conflict to achieve multiple effects together.

[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the protection required.
