[0021] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0022] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0023] Reference Figure 1 and Figure 2 As shown, ground film is a petrochemical product used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, etc., and promote plant growth; most of the existing ground films have relatively fixed specifications and shapes, and are in a layered and stacked state. In actual use, when some soil planting locations need to be thickened due to differences in temperature or other factors, the local ground film cannot be thickened, resulting in limitations in adjustment. In order to solve such problems, an adjustable locally thickened ground film is proposed, including a ground film group 1, wherein the ground film group 1 includes a first film 11 and a second film 12 distributed at intervals, an air-filled layer 111 with an adjustable thickness is formed between the first film 11 and the second film 12, and the edges of the first film 11 and the second film 12 are connected to ensure the sealing of the air-filled layer 111, and a magnetic suction component 2 is provided between the first film 11 and the second film 12, and the magnetic suction component 2 includes a first film 11 disposed near the first film 11 A first magnetic block 21 is provided on one side of the second film 12, and a second magnetic block 22 is provided on one side of the second film 12 to cooperate with the first magnetic block 21. The first magnetic block 21 and the second magnetic block 22 are adsorbed and fitted to form a local thickened area of ​​the inflation layer 111. The second film 12 is also provided with an inflatable member 3 for inflating the inflation layer 111. The combination of the first film 11 and the second film 12 in the ground film group 1 can form an inflation layer 111, and the purpose of local sealing of the inflation layer 111 can be achieved through the adsorption of the magnetic member 2, so that the local inflation layer 111 is expanded by inflating the inflatable member 3, thereby achieving the purpose of local thickening, ensuring that the thickness of the ground film group 1 changes, and the position of the sealed inflation layer 111 can be adjusted and changed according to the mutual adsorption of different first magnetic blocks 21 and second magnetic blocks 22, so as to achieve the purpose of local thickening, which is convenient and fast while greatly improving the practicality of the ground film.

[0024] It should be noted that the above-mentioned magnetic suction parts 2 are arranged in several groups in this embodiment, and the first washing block and the second magnetic suction block 22 extend on both sides to the side connection between the first film 11 and the second film 12; the purpose of this arrangement is to ensure that when the local inflation layer 111 is sealed, its sealing effect is guaranteed, thereby preventing the air in the sealed area after inflation from leaking out, thereby affecting the thickening effect.

[0025] Further, see Figure 2As shown in the figure, the dotted line is the connection between the first film 11 and the second film 12. When the first magnetic block 21 and the second magnetic block 22 at the two positions are sealed, the inflation layer 111 between the two sealing parts is in a sealed state. At this time, the inflation part 3 on the film group of this section is inflated. At this time, the sealing inflation layer 111 of this section will expand due to the inflation, thereby achieving the purpose of local thickening of the ground film group 1.

[0026] It should also be noted that the power source for the above-mentioned inflation is achieved through inflation and pressurization of external equipment.

[0027] In addition, the first magnetic block 21 and the second magnetic block 22 can be moved closer or separated by human power, and during the expansion and thickening of the aerated layer 111, the ground film itself has a certain ductility and will not rupture due to expansion.

[0028] It is worth mentioning that, referring to Figure 3 As shown, in this embodiment, the specific structure of the inflatable member 3 is as follows: the inflatable member 3 includes a plurality of air inlet bases 31 arranged on the second film 12, and an air inlet pipe section 311 for connecting to an external air inflating pipe is provided in the air inlet base 31, the air inlet pipe section 311 extends downward into the inflatable layer 111, and two valves 32 for opening or closing the air inlet pipe section 311 are provided in the air inlet pipe section 311, and the two valves 32 are abutted against each other at one end; by the arrangement of the air inlet base 31 and the air inlet pipe section 311, the air inflating pipe of an external inflatable device can be directly inserted into the air inlet pipe section, thereby pushing the two valves 32 to open, thereby achieving the purpose of inflation, and when the air inflating pipe is pulled out, the two valves 32 will reset the valves 32 to the abutting state due to their own elasticity and the internal air pressure of the inflatable layer 111, thereby achieving the closure of the air inlet pipe section 311.

[0029] It should be noted that the specific arrangement of the two valves 32 is as follows Figure 3 As shown, they cannot continue to rotate after abutting, thereby ensuring that the rotation angles of the two valves 32 are certain and that over-travel will not occur, thereby achieving the purpose of opening the air intake pipe section 311 outward. The rotation angle here can also be determined by the structure of the rotation center. Since it is a relatively mature existing technology, it will not be elaborated here.

[0030] In addition, after the above-mentioned ground film is thickened, in order to ensure that the ground film is deflated when not in use, in this embodiment, the first film 11 is also provided with a plurality of deflation holes 121 for deflation of the inflation layer 111; the purpose of deflation of the inflation layer 111 can be achieved by opening the deflation holes 121.

[0031] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manner derived by those skilled in the art based on the technical solution of the present invention also falls within the scope of protection of the present invention.
