Description

Technical Field

[0001] The utility model relates to the technical field of ground film covering structures, in particular to a cold-resistant ground film covering structure. Background Art

[0002] Ground film, also known as ground covering film, is a plastic film material commonly used in agricultural cultivation technology. It is mainly made of plastic materials such as polyethylene (PE) and its thickness is generally between 0.005 mm and 0.02 mm. The main function of ground film is to change the field microclimate by covering the soil surface, so as to increase soil temperature, maintain soil moisture, inhibit weed growth, reduce soil moisture evaporation, promote early maturity of crops and increase production. In actual use, ground film is generally used in seasons with lower temperatures and planting areas. The thickness of ground film is relatively thin, and the soil inside the ground film is easily affected by the external low temperature, resulting in a lower internal soil temperature, affecting the growth and survival of seeds and seedlings, and the cold resistance effect is poor, and it cannot be reused. Therefore, a cold-resistant ground film covering structure is now provided. Utility Model Content

[0005] Preferably, the two groups of PVC transparent plates are parallel to each other, and a hollow layer is provided between the PVC transparent plates.

[0006] Preferably, a first sealing plate and a second sealing plate are respectively provided on both sides of the frame, a clamping claw is provided on one side of the frame and the first sealing plate, and a clamping column is provided on the other side of the frame and one side of the second sealing plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] (1) The cold-resistant and heat-insulating effect is achieved by providing a frame, a window slot, a PVC transparent plate, a hollow layer and an O-ring. The fixed connection between the two groups of PVC transparent plates and the O-ring forms a sealed state between the PVC transparent plates, increases the overall thickness, and reduces the conduction of low temperature to the inside, effectively improving the cold-resistant and heat-insulating effect. At the same time, the PVC transparent plate is a transparent material, which does not affect the sunlight irradiation on the soil and plants, making the interior of the covering structure in a greenhouse state. The cooperation between the rubber ring and the through hole can fix the film, which is convenient for replacing the film, reduces the loss of the ground film, and is also convenient for reuse;

[0012] (2) The assembly effect is achieved by providing a frame, a clamping column, a clamping claw, a sealing strip, a docking convex strip and a docking groove. The clamping column and the clamping claw are arranged at the same horizontal height. The clamping claw can form a clamping state with the clamping column, and multiple sets of frames and the first sealing plate and the second sealing plate on both sides are assembled. At the same time, the cooperation of the docking convex strip and the docking groove can prevent the phenomenon of translation or misalignment between the frames. The sealing strip effectively improves the sealing effect, prevents the flow of internal and external air, and reduces the loss of temperature, so that the ground film covering structure has an assembly function;

[0013] (3) By providing a frame, a first sealing plate, a second sealing plate and a convex column, a positioning effect is achieved. The convex columns are evenly spaced at the bottom ends of the frame, the first sealing plate and the second sealing plate and can be inserted into the soil. The top frame, the first sealing plate and the second sealing plate are positioned to avoid the frame, the first sealing plate and the second sealing plate from being offset, thereby improving the flexibility of use.

[0024] Specifically, as shown in the figure, when in use, the two groups of PVC transparent plates 3 and the O-ring 13 are fixedly connected to form a sealed state between the PVC transparent plates 3, which increases the overall thickness and reduces the conduction of low temperature to the inside, effectively improving the cold resistance and heat preservation effect. At the same time, the PVC transparent plate 3 is a transparent material, which does not affect the sunlight irradiation on the soil and plants, so that the interior of the covering structure is in a greenhouse state;

[0026] Specifically, as shown in the figure, when in use, the clamping column 6 and the clamping claw 7 are set at the same horizontal height, and the clamping claw 7 can form a clamping state with the clamping column 6, so that multiple sets of frames 1 and the first sealing plates 4 and the second sealing plates 8 on both sides are assembled, and at the same time, the cooperation of the docking convex strip 11 and the docking groove 14 can prevent the phenomenon of translation or dislocation between the frames 1;

When the seedlings grow to a larger state, the film 16 can be torn off, or the rubber ring 5 and the film 16 can be directly removed. Then, a sealed state is formed between the two groups of PVC transparent plates 3, which increases the overall thickness and reduces the conduction of low temperature to the inside, effectively improving the cold resistance and heat preservation effect. At the same time, the PVC transparent plate 3 is made of transparent material and does not affect the sunlight irradiation on the soil and plants, so that the interior of the covering structure is in a greenhouse state, and finally the use of the cold-resistant mulch film covering structure is completed.
