Description

Technical Field

[0001] The present invention relates to the field of greenhouse greenhouses, and particularly to an agricultural greenhouse for fruit and vegetable cultivation. Background Art

[0002] The application of greenhouse greenhouses in fruit and vegetable cultivation has significant advantages. Through environmental regulation, resource intensification, and technology integration, it solves many limitations of traditional open-field cultivation. It not only significantly improves yield and quality but also reduces natural and market risks, conforming to the development direction of modern agriculture towards intensification, intelligence, and greenness, and has become an important tool for improving the quality and efficiency of modern agriculture.

[0003] During the use of greenhouse greenhouses, water droplets often adhere to the inner wall of the shed roof, which are formed by the condensation of internal water vapor. The plants in the greenhouse release a large amount of water vapor through transpiration, and the water on the surface of the irrigated or moist soil evaporates into the air and liquefies when it encounters the cold inner wall of the greenhouse. On the one hand, the condensed water droplets fall onto the leaves or the soil surface, increasing humidity and easily inducing fungal diseases (such as gray mold and downy mildew); on the other hand, the water droplets adhere to the surface of the covering material, reflecting or scattering sunlight, reducing the light transmittance, and affecting plant photosynthesis.

[0004] Currently, the methods for preventing condensed water droplets are as follows: improving the covering material, such as using an anti-dew film or coating a nano-hydrophobic coating, but the cost is high; optimizing the structural design of the greenhouse, increasing the inclination angle of the shed roof, etc. However, only when the water droplets accumulate to a large size can the gravity be used to accelerate the sliding of the water droplets, and small water droplets still have a light-reducing effect, and there is a lack of collection effect on the water droplets, and the water droplets falling on the ground still have a disease impact.

[0005] The present invention provides an agricultural greenhouse for fruit and vegetable cultivation, which physically removes and collects the attached water droplets by mechanical means and has a significant cost advantage. Summary of the Invention

Detailed implementation manners

[0029] Next, in combination with the attached Figures 1-8 A specific embodiment of the present invention will be elaborated in detail.

[0030] Referring to the attached Figures 1-2 , an agricultural greenhouse for fruit and vegetable planting includes a floor component. The floor component is buried underground and is used to stabilize the overall greenhouse. The floor component includes a fixed column 1. The fixed column 1 is directly buried in the soil layer, and a plurality of outward expanding rods 2 are rotatably connected thereto. The outward expanding rod 2 is rotatably connected to a first connecting rod 3. The end of the first connecting rod 3 is rotatably connected to a second connecting rod 4. The second connecting rod 4 is rotatably connected to the fixed column 1. The fixed column 1, the outward expanding rod 2, the first connecting rod 3, and the second connecting rod 4 form a collapsible or expandable umbrella-like structure. When in the non-installed state, the fixed column 1 and the outward expanding rod 2 are close to each other, reducing the space occupied. When directly buried in the soil layer, first dig a foundation pit, then place the expanded floor component in the foundation pit, and then backfill the soil to cover the floor component. By expanding the outward expanding rod 2, the contact area with the soil is increased, enhancing the wind resistance of the greenhouse.

[0031] Referring to the attached Figure 1 and Figure 3 , a straight bone rod 5 is connected to the fixed column 1. The upper end of the straight bone rod 5 is connected to a bent skeleton 6. A rod seat 7 is connected to the straight bone rod 5. A hoop 8 is rotatably provided on the rod seat 7. The hoop 8 is locked on the rod seat 7 through a fastener, so that the hoop 8 and the rod seat 7 can form a ring for locking the cross bone rod 9. The cross bone rod 9 plays a role in strengthening the stability of the greenhouse.

[0032] Referring to the attached Figure 5 and Figure 6, a slide rail 10 is connected to the bent framework 6, a slide seat 11 is slidably arranged on the slide rail 10, a bracket 12 is horizontally connected between adjacent slide seats 11, a sponge body 13 is arranged on the bracket 12, and the sponge body 13 abuts against the inner wall of the greenhouse roof. The slide seat 11 has the freedom to slide within the slide rail 10. During its sliding process, the sponge body 13 connected thereto makes an arc rotational movement, sweeping across the inner wall of the greenhouse, adsorbing the water droplets attached to the inner wall of the roof, preventing the water droplets from blocking sunlight, and avoiding the water droplets from sliding down along the inner wall of the greenhouse and falling on the soil layer.

[0033] A guide rod 14 equidistant from the slide rail 10 is also connected to the slide rail 10. The guide rod 14 penetrates the slide seat 11 to guide the sliding of the slide seat 11. At the same time, a through chute is arranged on the slide rail 10, and a support arm 15 is connected to the slide seat 11. The support arm 15 penetrates and cooperates with the chute on the slide rail 10. The chute also has a guiding effect on the support arm 15, eliminating the rotational freedom of the slide seat 11 relative to the guide rod 14.

[0034] Reference appendix Figures 5-8 , a sliding cylinder 16 is connected to the bracket 12, the sponge body 13 is connected to a connecting plate 17, a sliding convex 18 is connected to the connecting plate 17, the sliding cylinder 16 and the sliding convex 18 are slidably matched, a first spring 19 is sleeved outside the sliding cylinder 16, and both ends of the first spring 19 respectively contact the bracket 12 and the connecting plate 17. The first spring 19 is in a pre-compressed state, and the generated elastic force gently presses the sponge body 13 against the greenhouse wall.

[0035] A track convex 171 is arranged on the connecting plate 17, and a dovetail groove adapted to the track convex is arranged on the sponge body 13. The track convex 171 and the dovetail groove are matched. During installation, only need to laterally align the sponge body 13 with the track convex 171 on the connecting plate 17, and laterally push to install the sponge body 13 on the connecting plate 17, and complete the vertical position positioning of the sponge body. Further, limiting rods 20 are rotatably connected to both side walls of the connecting plate 17. After the sponge body 13 is laterally pushed and installed on the connecting plate 17, rotate the limiting rods 20 so that the two limiting rods 20 fit against the side wall of the sponge body 13 to position the sponge body 13 horizontally and prevent it from sliding out of place with the connecting plate.

[0036] The water absorption of the sponge body is mainly based on its unique porous structure and surface tension. The inside of the sponge body is composed of a large number of tiny pores and channels, which can accommodate water molecules. When the sponge contacts the water droplets on the inner wall of the greenhouse, the water molecules quickly diffuse into the interior through the pores, forming an adsorption force and fixing the water. The sponge body has a water absorption limit, which is jointly determined by the porosity, pore diameter, material type and crosslinking degree. Therefore, after using for a period of time in this embodiment, the adsorbed water droplets need to be squeezed out.

[0037] The bracket 12 is provided with guide posts 21, and an extrusion plate 22 is horizontally arranged above the sponge body 13. The extrusion plate 22 is slidably matched with the guide posts 21. When it is necessary to extrude the water adsorbed in the sponge body, the extrusion plate 22 can be pressed down. The extrusion plate 22 slides under the guidance of the guide posts 21 without dislocation.

[0038] Refer to the attached Figure 1 , the water extruded from the sponge body 13 needs to be collected to prevent the water from falling on the soil and changing the soil humidity and increasing the disease risk to crops. The operating position when extruding water in this embodiment is the position where the sponge body is close to the top of the straight bone rod 5, aiming to highly adapt to the human operating height, and the position of squeezing the sponge body each time is fixed. A water storage tray 23 is connected to the slide rail 10. When the sponge body 13 slides on the slide rail 10 to the bottom limit position of the slide rail 10, that is, above the water storage tray 23, the sponge body can be squeezed at this time to collect the extruded water through the water storage tray 23.

[0039] Refer to the attached Figures 5-8 , based on the characteristic that the position of the water storage tray 23 is fixed and the position of squeezing water from the sponge body each time is also fixed, in this embodiment, the extrusion plate 22 is linked to squeeze the sponge body through the extrusion action of the slidable bracket 12 and the positioning plate 24 fixed on the slide rail 10. Specifically, the positioning plate 24 is connected to the bottom of the slide rail 10; a first screw rod 25 is rotatably arranged on the support arm 15. The bottom end of the first screw rod 25 is connected with an extrusion disc 26. A second spring 27 sleeved on the first screw rod 25 is arranged between the extrusion disc 26 and the support arm 15. The top end of the first screw rod 25 is connected with a first runner 28. A second screw rod 28 is rotatably arranged on the bracket 12. A moving block 29 is arranged on the second screw rod 28. Both sides of the extrusion plate 22 are connected to the moving block 29 through a third connecting rod 30. A second runner 31 is key-connected to the second screw rod 28. The first runner 28 and the second runner 31 are connected through a conveyor belt 32.

[0040] When the bracket 12 slides to the bottom end of the slide rail 10, the extrusion disc 26 first contacts the positioning plate 24, and then the extrusion disc 26 stops at the positioning plate 24. The bracket 12 continues to move down. Based on the rotational limiting effect of the slide rail 10 on the support arm 15, the first screw rod 25 rotates under the thread fit of the support arm 15, the second spring 27 is compressed, and the rotating first screw rod 25 drives the second screw rod 28 to rotate, thereby driving the extrusion plate 22 to press down and squeeze the sponge body 13.

[0041] Refer to the attached Figures 4-5, the height of the greenhouse is beyond the limit that can be directly affected by the human height. In this embodiment, the following technical solution is adopted to control the sliding of the bracket 12 on the sliding rail 10: The sliding rail 10 is also connected with a wire rack 33. Rotating bead wheels 34 are provided at both ends of the wire rack 33. A pulling bead 35 is connected between the two bead wheels 34. And the support arm 15 is connected to the pulling bead 35. By pulling the pulling bead 35 to rotate between the two bead wheels 34, the sliding seat 11 is driven to slide on the guide rail 10, so as to control the sponge body 13 to completely sweep across the inner wall surface of the greenhouse.

[0042] The pulling bead 35 is in a tightened state, so that the part between the guide rail 10 and the wire rack 33 can be received by the wire rack 33. Without restriction, the pulling bead on the other side is straightly connected between the two bead wheels, which causes an obstacle to the spatial action of the drone and other devices. In this embodiment, the following technical solution is adopted to make the pulling bead close to the wire rack 33 section by section: A plurality of positioning bead wheels 36 are also rotatably connected to the wire rack 33. The pulling bead bypasses the bead wheels 34 at both ends and is close to the wire rack 33 under the action of the positioning bead wheels 36.

[0043] For the agricultural greenhouse for fruit and vegetable planting of the present invention, the wind resistance stability after the greenhouse is buried in the ground is strengthened through the floor component. The sponge body is controlled to slide closely along the inner wall of the greenhouse by the pulling bead, and the water droplets adsorbed on the inner wall of the greenhouse are adsorbed into the sponge body, ensuring the light transmittance of the greenhouse and reducing the influence of diseases on crops. After a period of time, the bracket can be pulled to the extreme position, and through the extrusion action with the positioning disc, the linkage extrusion plate extrudes the sponge body, and the accumulated water is extruded from the sponge body and received by the water storage tray.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
