Description

Technical Field

[0001] This utility model relates to the field of vegetable greenhouse technology, specifically to a cucumber greenhouse with a double-layer film that transmits light and provides shade. Background Technology

[0002] Cucumbers are a widely cultivated vegetable crop worldwide, and they are quite sensitive to environmental conditions such as light, temperature, and humidity. Cucumber greenhouses with double-layered films that provide both light transmission and shading are essential facilities to meet the needs of modern agriculture. The double-layered film structure effectively blocks heat transfer, providing insulation in winter and lowering the temperature inside the greenhouse in summer. Furthermore, the light transmission and shading film allows for flexible adjustment of light intensity according to the needs of different growth stages, ensuring sufficient light for cucumber photosynthesis while preventing scorching of the plants by strong sunlight. This type of greenhouse creates a stable and controllable environment for cucumber growth, playing a crucial role in improving yield and quality.

[0003] In the actual use of cucumber greenhouses, water droplets easily condense on the inner surface of the greenhouse film. These water droplets can stretch the film and affect its lifespan. When it snows, the snow accumulation on the roof can put a lot of pressure on the greenhouse, which may cause structural damage or even collapse. In view of this, we propose a cucumber greenhouse with a double-layer film that transmits light and provides shade. Utility Model Content

[0004] The purpose of this invention is to provide a cucumber greenhouse with a double-layer film that transmits light and provides shade, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cucumber greenhouse with a double-layered light-transmitting and sun-shading film includes a film greenhouse body. The film greenhouse body is supported by a structure formed by several horizontally arranged arc-shaped frame poles and several vertically arranged connecting poles that are interlocked and fixed. Several sun-shading films are installed inside the film greenhouse body. Several vertical poles are arranged horizontally inside the film greenhouse body. A straight pole is fixed between the top ends of several vertical poles. A pair of support arms are fixed at both ends of the straight pole. A film surface tapping mechanism is provided between the two support arms located on the same side of the straight pole. The film surface tapping mechanism is used to tap the inner surface of the film greenhouse body.

[0007] The membrane surface tapping mechanism includes a long shaft rotatably connected between two support arms on the same side of the straight rod, a plurality of levers rotatably rotating about the long shaft, a fixed rod fixed to the bottom end of the straight rod, and a tapping plate hinged to the bottom of the fixed rod. The levers, the fixed rod, and the tapping plate form a tapping assembly, and multiple tapping assemblies are provided on the long shaft.

[0008] A rotating motor is provided at the end of the long shaft. Several levers are fixed to the outer periphery of the long shaft in a centrally symmetrical manner. Second support rods are fixed at the left and right edges of the bottom of the striking plate. A convex shaft is fixed at the bottom end of the fixed rod. The end of the second support rod is sleeved on the outside of the convex shaft and rotatably connected to the convex shaft.

[0009] Preferably, the middle part of the shading film overlaps the straight rod, and the first and last ends of the shading film overlap the two connecting rods located at the front and rear ends of the film canopy, respectively.

[0010] In this setup, multiple overlapping points ensure that the shading film is securely laid inside the film canopy, facilitating adjustments to the shading range and angle.

[0011] Preferably, the rotary motor is fixed to the end of the support arm, and the end of the long shaft is coaxially connected to the end of the output shaft of the rotary motor;

[0012] In this configuration, the rotating motor ensures stable power transmission, guaranteeing smooth rotation of the long shaft and providing reliable power to the membrane surface tapping mechanism.

[0013] Preferably, a plurality of the levers are centrally symmetrically distributed around the periphery of two central sleeves, the central sleeves are fixed on the long shaft, and the central sleeves and the levers are fixedly connected by connecting posts;

[0014] This setting ensures uniform force distribution during long shaft rotation, reduces equipment vibration, and extends the service life of the membrane surface tapping mechanism.

[0015] Preferably, the convex shaft extends laterally through the bottom end of the fixing rod and is fixedly connected to the fixing rod. Both ends of the convex shaft are provided with stops, and the end of the second support rod is always restricted on the convex shaft by the obstruction of the stops.

[0016] This setup provides a stable pivot point for the second support rod while limiting its rotation range, ensuring the stability of the striking plate's trajectory.

[0017] Preferably, a pair of first support rods are fixed at the left and right edges of the bottom surface of the striking plate, and the ends of the first support rods are fixed to the corresponding second support rods.

[0018] This setting enhances the structural strength of the striking plate, making it less prone to deformation during striking and ensuring stable striking results.

[0019] Preferably, a through-hole is formed on the outer surface of the fixing rod, a pull rod is fixed to the bottom surface of the striking plate, and a baffle is fixed to the end of the pull rod after passing through the hanging groove;

[0020] This setting further limits the rotation angle of the tapping plate to prevent excessive rotation and improve the operational safety of the membrane surface tapping mechanism.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This cucumber greenhouse with a double-layered film that transmits light and provides shade features a film surface striking mechanism. This mechanism mechanically strikes the film during operation, causing vibrations that remove water droplets from the inner surface of the film, reducing the strain on the film. Additionally, during snowfall, it can promptly shake off accumulated snow from the roof, reducing the pressure on the greenhouse and ensuring structural stability and safe operation.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1-9 A cucumber greenhouse with a double-layered light-transmitting and sun-shading film includes a film greenhouse body 100. The film greenhouse body 100 is supported by a structure formed by several horizontally arranged arc-shaped frame rods 200 and several vertically arranged connecting rods 210, which are interlocked and fixed. The interlocking and fixing of the arc-shaped frame rods 200 and connecting rods 210 provides a stable support frame for the film greenhouse body 100, ensuring the overall structural strength of the greenhouse. Several sun-shading films 400 are installed inside the film greenhouse body 100, which can provide shade for cucumbers when the sunlight is too strong. Several vertical rods 300 are arranged horizontally inside the film greenhouse body 100. A straight rod 310 is fixed between the top of the vertical rods 300. A pair of support arms 320 are fixed at both ends of the straight rod 310. The vertical rods 300, the straight rods 310, and the support arms 320 together form a stable internal support structure, providing an installation foundation for subsequent installation of components such as the film surface tapping mechanism 500. The middle part of the shading film 400 is attached to the straight rod 310, and the first and last ends of the shading film 400 are attached to the two connecting rods 210 located at the front and rear ends of the film greenhouse 100, respectively. This overlapping method allows the shading film 400 to be stably laid in the greenhouse and is easy to install and dismantle.

[0040] like Figure 3 As shown, in this invention, a membrane surface tapping mechanism 500 is provided between two support arms 320 on the same side of the straight rod 310. The membrane surface tapping mechanism 500 is used to tap the inner surface of the film shed 100. The membrane surface tapping mechanism 500 provides an actuating component for removing water droplets and snow from the inner surface of the film shed 100.

[0041] like Figure 3 and Figure 4As shown, specifically, the membrane surface tapping mechanism 500 includes a long shaft 510 rotatably connected between two support arms 320 on the same side of the straight rod 310, a plurality of levers 520 axially rotating around the long shaft 510, a fixed rod 530 fixed to the bottom end of the straight rod 310, and a tapping plate 540 hinged to the bottom of the fixed rod 530. The levers 520, the fixed rod 530, and the tapping plate 540 form a tapping assembly, and multiple tapping assemblies are provided on the long shaft 510. The design of multiple tapping assemblies can increase the tapping range and frequency, so that the inner surface of the membrane structure 100 can be tapped more comprehensively, thereby improving the tapping effect.

[0042] like Figure 3 and Figure 4 As shown, a rotary motor 511 is further provided at the end of the long shaft 510. The rotary motor 511 is fixed to the end of the support arm 320, and the end of the long shaft 510 is coaxially connected to the end of the output shaft of the rotary motor 511. The rotary motor 511 provides a power source for the rotation of the long shaft 510 and the lever 520, ensuring that the membrane surface tapping mechanism 500 can operate continuously and stably.

[0043] like Figures 3-6 As shown, several levers 520 are centrally symmetrically distributed around the two central sleeves 521. The central sleeves 521 are fixed to the long shaft 510, and the central sleeves 521 and levers 520 are fixedly connected by connecting posts 522, so that the levers 520 are centrally symmetrically fixed to the outer periphery of the long shaft 510. The centrally symmetrical distribution of the levers 520 makes the force on the long shaft 510 more balanced when it rotates, reducing vibration and wear during equipment operation and extending service life.

[0044] like Figure 3 , Figure 4 and Figure 7 As shown, second support rods 542 are fixed to the left and right edges of the bottom end of the striking plate 540. Notably, a convex shaft 531 is fixed to the bottom end of the fixing rod 530. The end of the second support rod 542 is sleeved on the outside of the convex shaft 531 and rotatably connected to it. The convex shaft 531 extends laterally through the bottom end of the fixing rod 530 and is fixedly connected to it. Stops 532 are provided at both ends of the convex shaft 531. The end of the second support rod 542 is always restricted to the convex shaft 531 by the stops 532. The rotatable connection between the second support rod 542 and the convex shaft 531, combined with the limiting effect of the stops 532, provides a stable rotational fulcrum for the striking plate 540, preventing the second support rod 542 from detaching from the convex shaft 531 and ensuring the stability of the striking plate 540's trajectory during striking.

[0045] like Figure 7As shown, it is worth noting that a pair of first support rods 541 are fixed at the left and right edges of the bottom surface of the striking plate 540. The ends of the first support rods 541 are fixed to the corresponding second support rods 542. The setting of the first support rods 541 enhances the structural strength of the striking plate 540, making it less prone to deformation during the striking process and ensuring the striking effect.

[0046] like Figure 6 , Figure 8 and Figure 9 As shown, it should be added that a through-hole groove 533 is provided on the outer surface of the fixing rod 530, and a pull rod 543 is fixed to the bottom surface of the striking plate 540. The end of the pull rod 543 passes through the groove 533 and is fixed to a baffle 544. The cooperation of the groove 533, the pull rod 543 and the baffle 544 restricts the rotation angle of the striking plate 540, prevents the striking plate 540 from rotating excessively, and ensures the safe operation of the equipment.

[0047] It is worth noting that the rotary motor 511 involved in this utility model is existing conventional technology, and will not be described in detail here.

[0048] In this embodiment, the cucumber greenhouse with a double-layer film for light transmission and shading is used as follows: First, the rotating motor 511 is started, causing its output shaft to rotate. Power is stably transmitted to the long shaft 510 via a coaxial connection, causing the long shaft 510 to rotate. Then, the lever 520 fixed to the long shaft 510 rotates synchronously around its axial direction under the fixing action of the central sleeve 521 and the connecting column 522. When the rotating lever 520 reaches the contact position with the second support rod 542, it exerts a pushing force on the second support rod 542. Next, the second support rod 542 rotates around the sleeved convex shaft 531 as its rotation fulcrum, under the pushing action of the lever 520. The second support rod 542 is fixedly connected to the striking plate 540, thereby driving the striking plate 540 to move upward and lift the film shed 100. Subsequently, as the lever 520 continues to rotate around the convex shaft 531 and moves away from the second support rod 542, the striking plate 540, having lost its pushing force, gradually moves away from the film shed 100 under its own weight and with the assistance of the limiting structure formed by the pull rod 543, the hanging groove 533, and the baffle 544. Finally, under the continuous rotation of the rotating motor 511, the lever 520 repeatedly contacts, pushes, and separates from the second support rod 542, causing the striking plate 540 to continuously strike the film shed 100, thereby removing water droplets and snow from the inner surface of the film shed 100.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
