Description

Technical Field

[0001] The present invention relates to the field of agriculture, and in particular to a convenient seedling raising agricultural film system which is beneficial to improving covering efficiency. Background Art

[0002] At present, in order to keep warm and moist during seedling cultivation, it is necessary to build agricultural film around the seedbed to form a suitable environment for seedling growth. Traditional seedling cultivation agricultural film has many disadvantages in the process of use, which are mainly reflected in the following aspects:

[0003] Complex construction steps: The traditional agricultural film structure construction steps are cumbersome, involving a variety of metal or bamboo and wood components such as arch beams, brackets, etc., which require professional technicians to install and multiple people to cooperate during the installation.

[0004] Many materials and components: Traditional agricultural film structures require the use of a large number of metal or bamboo and wood components and supporting structures, which not only increases material costs, but also makes the construction and disassembly process complicated and time-consuming.

[0005] Difficult to dismantle: Due to its complex structure, traditional agricultural films require a huge amount of work to dismantle and rebuild when they need to be moved or relocated, which is not conducive to quickly responding to market demand.

[0006] Inconvenient transportation: Traditional agricultural film structures are large in size and have many components during the construction process, which leads to many restrictions in the transportation process, increasing logistics costs and time.

[0007] Easy to cause environmental pollution: Traditional agricultural films are generally disposable plastic films, which are usually abandoned in the wild after use. With the large-scale use of agricultural films, it is very easy to cause "white pollution".

[0008] In addition, the current agricultural film system is in a closed state. When encountering scorching heat, ventilation is required. When ventilating, the vents on the agricultural film system need to be opened manually, and then the vents need to be closed after the temperature drops. Therefore, a lot of manpower costs are required in daily operation. Summary of the invention

[0009] In view of the deficiencies in the prior art, the present invention provides a convenient seedling cultivation agricultural film system and a method of using the same which are beneficial to improving covering efficiency. The agricultural film system and the method of using the same can realize the rapid construction and disassembly of the agricultural film system, are convenient in transfer, transportation and storage, and the materials used are simple. Automatic ventilation and air permeability can be achieved during use, no additional manpower is required, the cost is low, and the system can be recycled and reused, which is environmentally friendly and pollution-free.

[0010] To achieve the above object, the present invention adopts the following technical solution: a convenient seedling raising agricultural film system that is beneficial to improving covering efficiency, comprising:

[0011] Two longitudinally arranged water injection members, both ends of which have sealing structures;

[0012] Several gas injection members, which include longitudinally arranged gas injection cylinders fixed on the two water injection members. Between the longitudinally arranged gas injection cylinders, several transverse gas injection pipes communicating with them are connected. After gas injection, the transverse gas injection pipes arch into an arc shape, and both ends of the longitudinal air channels also have sealing structures;

[0013] An agricultural film for covering, which is fixedly connected to the water injection members, and the agricultural film covers above the gas injection members;

[0014] Two self-rolling films, which are fixedly connected to both sides of the agricultural film. The self-rolling films include agricultural film layers, and multiple vertical fiber strips are arranged on the agricultural film layers.

[0015] Furthermore, both the water injection members and the gas injection members are made of agricultural film material.

[0016] Furthermore, after water injection, the water injection members are in a flat tube shape and are closely attached to the ground.

[0017] Furthermore, multiple thin pipelines are arranged on the self-rolling films, and clear water is injected into the thin pipelines.

[0018] Furthermore, the inner surface of the agricultural film is closely attached and fixed to the gas injection members or the water injection members.

[0019] Furthermore, both ends of the water injection members are tightened and sealed through pull belts, and the longitudinal air channels of the gas injection members are also tightened and sealed through pull belts.

[0020] Furthermore, at least one ventilation hole is opened on the self-rolling films. A self-rolling curtain is connected to the top of the ventilation hole, and multiple thin pipelines are connected to the bottom of the self-rolling curtain, and clear water is injected into the thin pipelines.

[0021] The present invention also discloses a usage method of a portable seedling-raising agricultural film system beneficial to improving the covering efficiency, including the following steps:

[0022] S1: Place the water injection members and the gas injection members on both sides of the seedling bed respectively, and inject air into the gas injection members thereon to make them expand and form arches, and seal the gas injection ports. After the gas injection members expand, they will push the agricultural film thereon upward and make it form an arc shape;

[0023] S2: Fill the water injection ports of the water injection members with clear water. After filling with clear water, the bottom of the water injection members fits with the ground, and finally seal the water injection ports;

[0024] S3: Inject clean water into the thin pipeline of the self-rolling film or self-rolling curtain. Under the action of gravity, the clean water will deposit at the bottom of the thin pipeline, increasing the weight of the bottom area of the self-rolling film or self-rolling curtain. At normal temperature or low temperature, the self-rolling curtain or self-rolling film is in a stretched state. At high temperature, the clean water in the thin pipeline of the self-rolling film or self-rolling curtain will gradually evaporate to form water vapor, which will move upward in the thin pipeline and adhere to it, reducing the weight of the bottom of the self-rolling film or self-rolling curtain. Due to the effect of thermal expansion and contraction, the self-rolling film or self-rolling curtain will self-roll, making the inside of the agricultural film system communicate with the outside world and realizing ventilation.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The agricultural film system and its usage method can realize the rapid erection and disassembly of the agricultural film system, greatly improving the agricultural film covering efficiency, and can also realize automatic ventilation according to temperature changes, reducing additional labor input;

[0027] 2. During the erection process, only by injecting sufficient water into the water injection component can the function of fixing the agricultural film be achieved. At the same time, after injecting sufficient water into the water injection component, the weathering speed of the water injection component can be effectively slowed down, increasing its service life;

[0028] 3. By using the air injection component to replace the metal or bamboo and wood arch beams, the cost is greatly reduced. And due to the counterweight effect of the water injection component, its strength is also sufficient. When disassembling, only need to exhaust the air in the air injection component and the clean water in the water injection component, which is convenient for folding and storage, occupying less space; Due to the convenience of erection and disassembly, the agricultural film system can be stored when not in use, effectively extending its life, slowing down the aging speed, and can also be reused, realizing ecological environmental protection and pollution reduction;

[0029] 4. Since the self-rolling film is adopted, when the weather is hot, the clean water in the thin pipeline will evaporate. After evaporation, the weight of the self-rolling film is reduced, and it can self-roll more smoothly, making the whole system ventilate; When the weather temperature is suitable, the evaporation speed of the water in the thin pipeline is slower. Under the action of gravity, the self-rolling film will naturally droop and stretch again, making the agricultural film system keep a sealed state, promoting heat preservation and moisture retention in the agricultural film system. In addition, the automatic shrinking and drooping of the agricultural film according to temperature changes effectively reduces the additional labor input cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] As Figures 1 to 5 shown, a portable seedling - raising agricultural film system conducive to improving the covering efficiency includes:

[0038] Two longitudinally arranged water injection members 2. When building the agricultural film 1 system, the water injection members 2 are located on both sides of the seedbed. Both ends of the water injection member 2 have a sealing structure. Through the sealing structure, the water injection member 2 can be quickly sealed after water injection to prevent clear water leakage;

[0039] Several air injection members, which include longitudinal air injection cylinders fixed on the two water injection members 2. The longitudinal air injection cylinders can be bonded to the water injection members 2. Between the longitudinal air injection cylinders, several transverse air injection pipes connected to them are provided. After air injection, the transverse air injection pipes arch into an arc shape, and both ends of the longitudinal air duct 7 also have a sealing structure;

[0040] An agricultural film 1 for covering, which is fixedly connected to the water injection member 2, and the fixing method can be bonding. The agricultural film 1 covers above the air injection member;

[0041] Two self - rolling films 4, the self - rolling films 4 are fixedly connected to both sides of the agricultural film 1. The self - rolling films 4 include an agricultural film layer, and a plurality of vertical fiber strips 6 are provided on the agricultural film layer.

[0042] When the present invention is in use, first place the water injection member 2 on both sides of the seedbed. The water injection member 2 is made of agricultural film material. To enhance its strength, its thickness is 2-3 times that of ordinary agricultural film. It can also be made of PVC material or rubber material like an inflatable swimming ring, which is convenient for folding and storage. The length of the water injection member 2 matches the length of the seedbed. First, inject clear water into the water injection member 2. After the clear water is injected, seal the water injection port. Then, inject gas into the air injection member to make the air injection member expand and form. After the air injection member expands and forms, it will lift the agricultural film 1 and cover it above the water injection member 2. Among them, the agricultural film 1 can be connected to the water injection member 2 through its two side edges, such as being fixed with strong glue. In this system, when the weather is hot, due to the different thermal expansion coefficients of the fiber strip and the agricultural film layer of the self-rolling film, the thermal expansion coefficient of the fiber strip is larger. If the fiber strip expands at high temperature, it will expand along its own length direction (vertically upward). At this time, it will generate an upward pulling force on the outer bottom of the agricultural film. This upward pulling force will cause the bottom of the agricultural film to have an outward movement tendency, and finally make the bottom of the agricultural film turn outward and wind up to form a winding part. Therefore, the self-rolling film 4 can roll up and keep a certain distance from the ground, thus realizing the ventilation and air permeability of the entire agricultural film 1 system. When the temperature is suitable (such as at night), it can stretch and maintain the sealed state of the system to achieve heat preservation and moisture preservation. Through the above structure of the agricultural film 1 system, the rapid preparation of the entire agricultural film 1 system can be realized. After preparation, its rapid transportation and installation can be realized, and the construction efficiency can also be greatly improved. Moreover, the operation is simple, the technical requirements for operators are low, and it is convenient for popularization and application. The agricultural film 1 system has good environmental adaptability. Since the air injection member is used to support the agricultural film 1 and the air injection member is in a flexible state as a whole with good ductility, even when the weather is windy, the agricultural film 1 and the air injection member as a whole will deform, and after the strong wind stops, the agricultural film 1 and the air injection member will return to their original states. However, for traditional agricultural films, since the agricultural film is covered on a rigid member, the agricultural film is easily damaged when encountering strong wind weather.

[0043] Further, after the water injection, the water injection member 2 is in a flat cylindrical shape and closely adheres to the ground. Specifically, after the water injection, the water injection member 2 is in a flat cylindrical shape and closely adheres to the ground. In this way, its degree of expansion remains at a low level, and it can have ductility and is not easily damaged when encountering external forces.

[0044] Further, a plurality of thin pipelines 5 are provided on the self-rolling film 4, and clear water is injected into the thin pipelines 5. Through the arrangement of the thin pipelines 5 and the injection of an appropriate amount of clear water therein, the bottom of the self-rolling film 4 has a greater weight. When the temperature rises, the clear water in the thin pipelines 5 evaporates upward, and water vapor or water droplets condensed from the water vapor are located in the upper part of the thin pipelines 5. The amount of clear water at the bottom of the thin pipelines 5 decreases, and its weight is greatly reduced. At this time, due to the fiber strips 6 on the self-rolling film 4, under the action of thermal expansion and contraction, the self-rolling will occur better. In the case of a lower temperature, the evaporation amount decreases, and a large amount of clear water accumulates at the bottom of the thin pipes, so it can be better unfolded.

[0045] Further, the inner surface of the agricultural film 1 is closely fixed to the gas injection member or the water injection member 2. Specifically, the agricultural film 1 of the present invention is adhered to the gas injection member or the water injection member 2 through its inner surfaces on both sides. In this way, it is more convenient during its assembly.

[0046] Further, both ends of the water injection member 2 are tied and sealed through the pulling belts 8, and the longitudinal air ducts 7 of the gas injection member are also tied and sealed through the pulling belts 8. Specifically, the water injection member 2 of the present invention can be open at both ends or open at one end. When it is open at both ends, first tie and seal one end through the pulling belt 8, then inject water at the other end. After the water injection is completed, tie and seal the other end. In addition, the gas injection member can also be set to be open at both ends or open at one end. When it is open at both ends, first tie and seal one end through the pulling belt 8, then inject gas at the other end. Since the longitudinal air duct 7 is connected to the transverse air duct 3, when injecting gas from the longitudinal air duct 7, the gas will fill the transverse air duct 3 and the other longitudinal air duct 7. After the gas injection is completed, tie and seal the other end.

[0047] The present invention also includes a method for using a portable seedling-raising agricultural film 1 system that is beneficial to improving the covering efficiency, including the following steps:

[0048] S1: Place the water injection member and the gas injection member on both sides of the seedbed respectively, inject air into the gas injection member thereon to make it expand and form an arch, close the gas injection port. After the gas injection member expands, it will push the agricultural film thereon upward and make it form an arc;

[0049] S2: Fill the water injection port of the water injection member with clear water. After filling with clear water, the bottom of the water injection member fits with the ground, and finally close the water injection port;

[0050] S3: Inject clean water into the thin pipeline 5 of the self-rolling film 4 or the self-rolling curtain. Under the action of gravity, the clean water will deposit at the bottom of the thin pipeline 5, increasing the weight of the bottom area of the self-rolling film 4 or the self-rolling curtain. At normal temperature or low temperature, the self-rolling curtain or the self-rolling film 4 is in a stretched state. At high temperature, the clean water in the thin pipeline 5 of the self-rolling film 4 or the self-rolling curtain will gradually evaporate to form water vapor, which will move upward in the thin pipeline 5 and adhere to it, reducing the weight of the bottom of the self-rolling film 4 or the self-rolling curtain. Due to the effect of thermal expansion and contraction, the self-rolling film 4 or the self-rolling curtain will self-roll, connecting the inside of the agricultural film system with the outside world and realizing ventilation.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
