Description

Technical Field

[0001] The utility model relates to the field of agricultural greenhouses, in particular to an anti-ultraviolet double-film greenhouse. Background Art

[0002] As greenhouse planting gradually matures, greenhouse insulation blankets are increasingly valued by farmers as the "cotton-padded clothes" of greenhouses. However, the traditional straw curtains and quilts used as greenhouse insulation blankets are heavy, have poor light transmittance, and are not waterproof, which greatly restricts the use and insulation effect of greenhouse insulation blankets.

[0003] In recent years, a greenhouse insulation blanket made of multiple layers of non-woven fabric has appeared. Although it is lighter, more translucent and more flexible to use than traditional straw curtains and quilts, farmers need to cover the upper and lower parts of the insulation blanket with a layer of film when using it. The laying operation is repetitive, time-consuming and labor-intensive, and the insulation effect is poor. Once the insulation blanket gets wet in rainy and snowy weather, it will lose its insulation effect and affect plant growth.

[0004] The existing greenhouse structure frame is simple, and the simple greenhouse frame will lead to poor overall stability of the greenhouse. When encountering strong winds, the greenhouse itself will bear the wind pressure. The outside of the traditional greenhouse is only covered with a layer of plastic film, which cannot withstand the wind pressure generated by strong winds. The plastic film is easily damaged, resulting in damage to the entire greenhouse. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the above-mentioned traditional technology and provide a UV-proof double-film greenhouse which is waterproof, heat-insulating and easy to lay and roll.

[0006] The purpose of this utility model is achieved through the following technical measures:

[0007] A UV protection double-film greenhouse, characterized in that: it includes a greenhouse support frame, a plurality of the greenhouse support frames are provided, and the plurality of the greenhouse support frames are evenly distributed, the plurality of the greenhouse support frames are fixedly connected with an arc-shaped greenhouse top frame, a plurality of frame connecting rods are fixedly connected between the plurality of the greenhouse top frames, a plastic greenhouse film is fixedly connected to the greenhouse top frame and the outer side of the greenhouse support frame, a winding assembly is connected to one side of the greenhouse support frame, a pulling assembly is connected to the other side of the greenhouse support frame, the winding assembly is connected to an outer protective film, the outer protective film includes a high-tensile non-woven fabric, the upper surface of the high-tensile non-woven fabric is fixedly connected with a non-glue cotton cloth, the upper surface of the non-glue cotton cloth is connected with a waterproof layer, the lower surface of the high-tensile non-woven fabric is fixedly connected with an upper layer of pure white felt, and the lower surface of the upper layer of pure white felt is fixedly connected with a lower layer of pure white felt.

[0008] As an improvement: the winding assembly includes a winding fixed plate, two of which are provided, a winding motor is fixedly connected to the side of one of the winding fixed plates, and an output end of the winding motor passes through the winding fixed plate.

[0009] As an improvement: the output end of the winding motor is fixedly connected to one end of the winding roller, the other end of the winding roller is rotatably connected to another winding fixed plate, and the winding roller is arranged to be wrapped with an outer protective film.

[0010] As an improvement: a partition is fixedly connected to the outside of the greenhouse support frame, and a plurality of partitions are provided. The winding roller passes through the plurality of partitions, and a protective shell is fixedly connected between two of the winding fixed plates.

[0011] As an improvement: the pulling assembly includes a pulling fixing plate, two pulling fixing plates are provided, and the two pulling fixing plates are fixedly connected to the outer side of the greenhouse support frame.

[0012] As an improvement: a pulling motor is fixedly connected to the side of the pulling fixed plate, the output end of the pulling motor passes through the pulling fixed plate, the output end of the pulling motor is fixedly connected to one end of a pulling roller, and the other end of the pulling roller is rotatably connected to another pulling fixed plate.

[0013] As an improvement: a plurality of winding wheels are fixedly connected to the pulling roller, a pulling rope is wound around the plurality of winding wheels, and the pulling rope is fixedly connected to the high-tensile non-woven fabric.

[0014] As an improvement: the plastic greenhouse film comprises a lower plastic film, the lower plastic film is fixedly connected to the greenhouse support frame and the greenhouse top frame respectively, and the outer side of the lower plastic film is fixedly connected to the upper plastic film.

[0015] Due to the adoption of the above technical solution, compared with the prior art, the utility model has the following advantages:

[0016] The outer protective film can be effectively waterproofed through the waterproof layer. When encountering rainy and snowy weather, water can be prevented from penetrating into the lower layer to affect the thermal insulation effect of the outer protective film. The multi-layer structure composed of the non-glue cotton cloth, the upper pure white felt and the lower pure white felt can effectively isolate the sunlight and ultraviolet rays. The high-tensile non-woven fabric can provide stability for the whole. The high-tensile non-woven fabric can ensure the pressure resistance for the whole and ensure its own strength during the pulling process. The outer protective film can be conveniently rolled up and stored through the winding component. The rolled up and stored outer protective film is stored in the protective shell to prevent the influence of rain and snow. By setting a pulling component and winding the pulling rope around the winding wheel, the rolled-up outer protective film can be unfolded again. The pulling rope is connected to the high-tensile non-woven fabric to ensure the stability of the pulling. Through the cooperation of the winding component and the pulling component, the outer protective film can be retracted and released conveniently and efficiently. The double-layer design of the plastic greenhouse film can not only achieve better thermal insulation effect, but also increase the overall strength. When damage occurs, it can be discovered and replaced and repaired while ensuring normal use. The double-layer structure of the plastic greenhouse film can also achieve better wind resistance, which can prevent damage to the plastic film caused by excessive wind pressure.

The arc structure can also better disperse the pressure from top to bottom of the greenhouse, and the multiple frame connecting rods 3 can ensure the integrity of multiple greenhouse support frames 1 and multiple greenhouse top frames 2, thereby ensuring the stability of the greenhouse support frame 1 and the greenhouse top frame 2, thereby increasing the wind and pressure resistance of the present application.

[0026] The upper pure white felt 54 and the lower pure white felt 55 are provided to ensure the thermal insulation performance of the outer protective film 5. The non-glue cotton cloth 52, the upper pure white felt 54 and the lower pure white felt 55 form a multi-layer structure to achieve ultraviolet protection. The waterproof layer 51 can effectively prevent rainwater from wetting the outer protective film 5, thereby ensuring the thermal insulation performance of the outer protective film 5. The high-tensile non-woven fabric 53 can ensure the overall strength and the flatness of the outer protective film 5 when unfolded.

[0027] The winding assembly 6 includes a winding fixed plate 64, two of which are provided. A winding motor 61 is fixedly connected to the side of one of the winding fixed plates 64, and the output end of the winding motor 61 passes through the winding fixed plate 64. The output end of the winding motor 61 is fixedly connected to one end of a winding roller 62, and the other end of the winding roller 62 is rotatably connected to the other winding fixed plate 64.

When the upper plastic film 41 is damaged, the lower plastic film 42 can also be used normally, thereby ensuring that the upper plastic film 41 is replaced and repaired even if it is found under the premise of normal use.

[0032] Working principle: When the greenhouse needs to be opened and the outer protective film 5 needs to be rolled up, the winding motor 61 rotates to drive the winding roller 62 to rotate, thereby winding the outer protective film 5 around the winding roller 62. The protective shell 63 can protect the outer protective film 5 in the stored state.
