Description

Technical Field

[0001] This invention relates to the field of agricultural greenhouse technology, and in particular to a protective device for agricultural greenhouses and an agricultural greenhouse. Background Technology

[0002] With the development of modern agriculture, greenhouses have been widely used as an important production tool. Existing agricultural greenhouses are usually equipped with winch systems, which adjust the ventilation and sealing of the greenhouse by rolling up the plastic film. For example, CN220630287U discloses a rainwater harvesting irrigation system, including a greenhouse frame and a roof. The roof is a transparent plastic film. The greenhouse frame includes several columns, with crossbeams movably connected to the columns. A drive mechanism (winch) on the columns drives the crossbeams to move up and down. Vertically arranged connecting rods are fixed on the crossbeams. The top of the connecting rods is connected to the middle of the roof, and the two sides of the roof are fixed to the greenhouse frame.

[0003] However, in practical applications, the direct friction between the connecting rods and the greenhouse beams can damage the plastic film over time. This not only shortens the lifespan of the plastic film and increases maintenance costs, but may also affect the growing environment of crops, leading to a decline in agricultural production efficiency.

[0004] Therefore, an effective solution is urgently needed to address this problem. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art by providing a protective device for agricultural greenhouses and an agricultural greenhouse. The protective device isolates the connecting rod of the winch from the greenhouse beams, thereby preventing the plastic film from being damaged by friction.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] The first objective of this invention is to provide a protective device for agricultural greenhouses, the protective device comprising a film-pressing groove pad body and film-pressing groove fasteners; the film-pressing groove fasteners are connected to both sides of the bottom of the film-pressing groove pad body; a first film-pressing groove and a second film-pressing groove are formed between the film-pressing groove pad body and the film-pressing groove fasteners; the first film-pressing groove is disposed on both sides of the second film-pressing groove; the first film-pressing groove is used to cooperate with the greenhouse beam frame to press the plastic film between the first film-pressing groove and the greenhouse beam frame; the film-pressing groove pad body has a strip-shaped structure.

[0008] Furthermore, multiple pressure groove fasteners are connected to both sides of the bottom of the pressure groove pad body, and the multiple pressure groove fasteners connected to each side are spaced apart to increase the stability of the connection.

[0009] Furthermore, both the pressure liner pad body and the pressure liner fastener are plastic parts, made of high-strength, wear-resistant and weather-resistant materials, specifically polyethylene (high-density polyethylene), polycarbonate, etc., which ensures sufficient flexibility to adapt to contact surfaces of different shapes and has excellent durability; the pressure liner pad body and the pressure liner fastener are integrally formed.

[0010] Furthermore, the main body of the pressure-molding groove pad has a bendable structure.

[0011] Furthermore, the main body of the pressure molding groove pad is provided with through holes; multiple through holes are arranged along the length of the main body of the pressure molding groove pad. The through holes can save materials on the one hand, increase flexibility on the other hand, facilitate bending, and facilitate observation of whether the installation is in place.

[0012] Furthermore, one end of the pressure-molding groove pad body is provided with a first connecting part, and the other end is provided with a second connecting part; the first connecting part and the second connecting part are shaped to match; two adjacent pressure-molding groove pad bodies are connected by the cooperation of the first connecting part of one pressure-molding groove pad body and the second connecting part of the other pressure-molding groove pad body.

[0013] Furthermore, the protective device for the agricultural greenhouse also includes reinforcing ribs; the reinforcing ribs are located at the bottom of the main body of the film pressing groove pad, and the reinforcing ribs can increase the strength of the main body of the film pressing groove pad, making it more durable.

[0014] Furthermore, the top of the pressure film groove pad body includes a connecting rod support surface and inclined surfaces that connect with both sides of the connecting rod support surface; the connecting rod support surface is used to support the connecting rod; the inclined surfaces are inclined and connect with the connecting rod support surface at their highest point.

[0015] The second objective of this invention is to provide an agricultural greenhouse that includes the aforementioned protective device, wherein the agricultural greenhouse further includes a greenhouse frame, a plastic film, and connecting rods; the greenhouse frame, plastic film, protective device, and connecting rods are arranged sequentially from bottom to top.

[0016] Furthermore, the greenhouse beam frame includes a beam frame body and snap-fit ​​parts connected to both sides of the beam frame body; the snap-fit ​​parts cooperate with the first pressing groove; the snap-fit ​​parts on both sides of the beam frame body are arranged opposite to each other.

[0017] Furthermore, the plastic film includes a film body and a movable curtain; the film body is connected to the movable curtain; the film body is located between the greenhouse beam and the protective device; the movable curtain can be rolled up on the connecting rod or laid out.

[0018] Furthermore, the film body has a notch in the middle, and the movable curtain can be laid out above the notch and completely cover the notch. The size of the movable curtain is larger than the size of the notch.

[0019] Furthermore, by sliding the connecting rod, the length of the movable curtain wound on the connecting rod can be adjusted to regulate the ventilation and sealing status inside the agricultural greenhouse. When the movable curtain is fully wound on the connecting rod, it is most conducive to ventilation and least conducive to sealing. When the movable curtain is fully unfolded, it is least conducive to ventilation and most conducive to sealing.

[0020] Furthermore, the greenhouse beam frame is an arc-shaped structure, a straight structure, or a combination of arc-shaped and straight structures; the shape of the pressure-film groove pad body matches that of the greenhouse beam frame.

[0021] Furthermore, multiple protective devices are connected end to end in sequence; multiple greenhouse beams are arranged in parallel; and the connecting rod is horizontally mounted on multiple greenhouse beams.

[0022] Furthermore, the agricultural greenhouse also includes a winch connected to a connecting rod for winding and unwinding plastic film.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1) This technical solution provides a protective device for agricultural greenhouses, which is used to isolate the connecting rod of the winch from the greenhouse beam frame. It effectively separates the main body of the plastic film from the connecting rod, thereby avoiding damage to the plastic film due to friction, ensuring the integrity and service life of the plastic film, reducing the need for frequent replacement, and also avoiding direct friction between the connecting rod and the greenhouse beam frame.

[0025] 2) This technical solution provides a protective device for agricultural greenhouses. The protective device is equipped with a film pressing groove fastener and adopts a snap-fit ​​connection to ensure that it will not shift during operation, thereby improving stability and operating efficiency, reducing maintenance costs, and facilitating installation and disassembly, as well as subsequent maintenance and replacement.

[0026] 3) The protective device for agricultural greenhouses provided by this technical solution is durable and easy to use. Attached Figure Description
