Description

Technical Field

[0001] This utility model relates to the field of agricultural crop cultivation technology, specifically a protective device for melon cultivation. Background Technology

[0002] Cucurbit cultivation protection devices are growth aids specifically designed for cucurbit crops (such as pumpkins, watermelons, and melons). They primarily provide protection for key growth parts and vulnerable areas of cucurbit crops, while also preventing the impact of extreme weather and pests on them.

[0003] When the weather is too hot, the growth of melons is affected. Existing melon cultivation protection devices usually use shade nets to protect the melon plants from direct sunlight, which can cause sunburn on the plants and fruit peels and affect subsequent growth.

[0004] However, existing technologies have the following shortcomings:

[0005] The inability to flexibly adjust the unfolding range of the shade net makes it impossible to adjust the degree of shading, thus failing to meet the light requirements of different types of melons, affecting melon ripening, reducing the taste and quality of melons, lowering market competitiveness, and impacting sales.

A connecting plate moves the corresponding first or second sliding rod, thereby covering the greenhouse with the corresponding shading film. By switching the connecting plate to different fixed plates, the device switches between first and second shading films with different shading intensities to meet the different shading needs of different melons. Simultaneously, a controller adjusts the output power of a third motor, thereby adjusting the number of rotations of the third motor and the sliding distance of the first and second sliding rods, thus adjusting the unfolding range of the shading film. This satisfies the light requirements of the same melon at different growth stages, preventing excessive sun exposure or insufficient light, promoting faster ripening, improving the taste and quality of the melons, and ultimately enhancing market competitiveness and facilitating sales.

[0019] 2. The present invention provides a protective device for melon cultivation. By designing a first sliding sleeve and a second sliding sleeve, when the rotating component drives the first sliding rod and the second sliding rod to slide inside the corresponding slide rail, the first sliding rod and the second sliding rod will simultaneously drive the first sliding sleeve and the second sliding sleeve on their outer walls to move together. By designing a sliding sleeve that is rotatably connected to the sliding rod and slides in the groove opened in the slide rail, the friction force of the sliding rod sliding in the slide rail can be reduced, which is beneficial to reducing the wear of both, increasing the service life of the device, improving the maintenance efficiency of the device, and reducing maintenance costs.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0034] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] Examples, such as Figures 1-10 As shown, a protective device for melon cultivation includes a greenhouse 1 located at the top of the ground 28 and multiple base plates 33, as well as a shading mechanism and two drive mechanisms. The two drive mechanisms are located between the multiple base plates 33, and the shading mechanism is located between the two drive mechanisms. It should be noted that support piles (not shown in the figure) are pre-embedded in the soil of the ground 28 at the bottom of the greenhouse 1, and the top of the support piles is fixedly connected to the bottom of the base plate 33.

[0036] The shading mechanism includes a first shading film 2, a second shading film 3, a first shading component, and a second shading component. The first shading component is positioned above the greenhouse 1, the second shading component is positioned above the first shading component, the first shading film 2 is positioned inside the first shading component, and the second shading film 3 is positioned inside the second shading component.

[0037] Each drive mechanism includes an arc-shaped strip 4, a mounting plate 13, a rotating assembly, a guide assembly, and a connecting assembly. The arc-shaped strip 4 is fixed between two base plates 33. The mounting plate 13 is located on one side of the arc-shaped strip 4. The guide assembly is located between the arc-shaped strip 4 and the mounting plate 13. The connecting assembly is located on one side of the mounting plate 13. It should be noted that both ends of the bottom of each arc-shaped strip 4 are welded to the base plate 33 at the top of the support pile.

[0038] like Figures 1-10 As shown, the first shielding assembly includes a first storage box 5, a first sliding rod 6, a first motor 29, a first roller 30, two first slide rails 7, and four first support frames 8. Each first support frame 8 is fixedly mounted on the top of the base plate 33. The first storage box 5 is fixedly mounted on the top of the ground 28 and is located between two of the first support frames 8. Each first slide rail 7 is fixedly mounted between the tops of two of the first support frames 8. The two ends of the first sliding rod 6 are slidably connected to the two first slide rails 7 respectively. The first motor 29 is fixedly mounted. Installed at one end of the first storage box 5, the first roller 30 is rotatably set at both ends inside the first storage box 5, the output end of the first motor 29 passes through the first storage box 5 and is fixedly connected to one end of the first roller 30, the first sunshade film 2 is located inside the first storage box 5, one end of the first sunshade film 2 is fixedly connected to the outer wall of the first roller 30, and the other end of the first sunshade film 2 is fixedly connected to the outer wall of the first sliding rod 6. Here, it should be noted that each first slide rail 7 is welded to the bottom plate 33 at the top of the support pile through two first support frames 8.

[0039] When shading is needed for the melon plants inside greenhouse 1, and the light intensity is relatively strong, the connecting component connects to the first sliding rod 6. The rotating component moves the connecting component along the arc-shaped strip 4, thereby moving the first sliding rod 6. Simultaneously, the first motor 29 drives the roller 30 to rotate, causing the roller 30 to release the first shading film 2. The released first shading film 2, in conjunction with the movement of the first sliding rod 6, keeps the first shading film 2 in a relatively taut state. As the first sliding rod 6 moves, it moves under the guidance of the two first slide rails 7. When the movable rod 6 moves from left to right along the two first slide rails 7, it will drive the first shading film 2, which is fixedly connected to the first sliding rod 6, to move together. Since the other end of the first shading film 2 is fixed inside the first storage box 5, when the first sliding rod 6 slides from the leftmost end to the rightmost end along the two first slide rails 7, it will drive the first shading film 2 to cover the outside of the greenhouse 1. Thus, the first shading film 2 on the first sliding rod 6 covers the outside of the greenhouse 1, protecting the melon plants inside the greenhouse 1 and preventing them from being damaged by the high temperature outside.

[0040] When the light intensity decreases and the melon plants can receive sunlight, the controller drives the rotating component to move in the opposite direction on the arc-shaped bar 4, thereby driving the first sliding rod 6 to move in the opposite direction. At the same time, the first motor 29 rotates, driving the first roller 30 to rotate in the opposite direction, rolling up the first shading film 2 until the first sliding rod 6 moves above the first storage box 5. At this time, the first shading film 2 will be rolled up inside the first storage box 5, making it convenient for the next shading operation of the melon plants inside the greenhouse 1.

[0041] like Figures 1-10As shown, the second shielding assembly includes a second storage box 9, a second sliding rod 10, a second motor 31, a second roller 32, two second slide rails 11, and four second support frames 12. Each second support frame 12 is fixedly mounted on the top of the base plate 33. The two second slide rails 11 are respectively fixedly mounted on the top of the four second support frames 12. The second storage box 9 is fixedly mounted on the top of the ground 28, and the second storage box 9 is located between two of the second support frames 12. Each second slide rail 11 is fixedly mounted between the tops of two of the second support frames 12. The two ends of the second sliding rod 10 are respectively connected to the two second slide rails 12. The second motor 31 is fixedly installed at one end of the second storage box 9. The second roller 32 is rotatably set at both ends inside the second storage box 9. The output end of the second motor 31 passes through the second storage box 9 and is fixedly connected to one end of the second roller 32. The second sunshade film 3 is located inside the second storage box 9. One end of the second sunshade film 3 is fixedly connected to the outer wall of the second roller 32. The other end of the second sunshade film 3 is fixedly connected to the outer wall of the second sliding rod 10. It should be noted that each second slide rail 11 is welded to the bottom plate 33 at the top of the support pile through two second support frames 12.

[0042] When shading is needed for the melon plants inside greenhouse 1, and the light intensity is very strong, the connecting component is connected to the second sliding rod 10. The rotating component moves the connecting component along the arc-shaped strip 4, thereby moving the second sliding rod 10. Simultaneously, the second motor 31 drives the second roller 32 to rotate, causing the second roller 32 to release the second shading film 3. The released second shading film 3, in conjunction with the movement of the second sliding rod 10, keeps the second shading film 3 in a relatively taut state. As the second sliding rod 10 moves, it moves under the guidance of the two second slide rails 11. When the second sliding rod 10 moves along the two second slide rails 11, it will drive the second shading film 3, which is fixedly connected to the second sliding rod 10, to move from left to right. Since the other end of the second shading film 3 is fixed inside the second storage box 9, when the second sliding rod 10 slides along the two second slide rails 11 from the leftmost end to the rightmost end, it will drive the second shading film 3 to cover the outside of the greenhouse 1. Thus, the second shading film 3 on the second sliding rod 10 covers the outside of the greenhouse 1, protecting the melon plants inside the greenhouse 1 and preventing them from being damaged by the high temperature outside.

[0043] When the light intensity decreases and the melon plants can receive sunlight, the controller drives the rotating component to move in the opposite direction on the arc-shaped bar 4, thereby driving the second sliding rod 10 to move in the opposite direction. At the same time, the second motor 31 drives the second roller 32 to rotate in the opposite direction, rolling up the second shading film 3 until the second sliding rod 10 moves above the second storage box 9. At this time, the second shading film 3 will be rolled up inside the second storage box 9, making it convenient for the next shading operation on the melon plants inside the greenhouse 1.

[0044] like Figures 1-10 As shown, the rotating assembly includes a third motor 14, a gear 15, and a rack 16. The rack 16 is fixedly disposed on one side of the top of the arc-shaped bar 4. The third motor 14 is fixedly disposed on one side of the mounting plate 13. The gear 15 is fixedly disposed on the side of the mounting plate 13 away from the third motor 14. The output end of the third motor 14 passes through the mounting plate 13 and is fixedly connected to the middle of the gear 15. The gear 15 and the rack 16 mesh with each other.

[0045] When the drive connection component needs to be moved, the third motor 14 is controlled to work, which drives the gear 15 to rotate. Since the mounting plate 13 moves on the arc strip 4 under the guidance of the guide component, when the gear 15 rotates, it will move itself under the action of the rack 16, thereby driving the mounting plate 13 and the connection component to move under the guidance of the guide component, and driving the required shading film to cover the outer wall of the greenhouse 1.

[0046] like Figures 1-10 As shown, the guide assembly includes a first guide rail 17, a second guide rail 18, and multiple guide wheels 19. The first guide rail 17 and the second guide rail 18 are respectively fixed on the inner and outer side walls of the arc-shaped strip 4. Each guide wheel 19 is rotatably mounted on one side of the mounting plate 13 via a connecting shaft, and the multiple guide wheels 19 are slidably connected to the two first guide rails 17 and the two second guide rails 18 respectively.

[0047] When the mounting plate 13 moves, the multiple guide wheels 19 rotatably mounted above the mounting plate 13 will move on the first guide rail 17 and the second guide rail 18. The first guide rail 17 and the second guide rail 18 limit and guide the multiple guide wheels 19 to prevent the gear 15 from deviating when it moves on the rack 16, which would cause the mounting plate 13 to deviate and affect the coverage effect of the shading film on the fruits and vegetables inside the greenhouse 1, resulting in shading omissions.

[0048] like Figures 1-10As shown, the connecting assembly includes a connecting plate 20, two fixing plates 21, two bolts 22 and two threaded grooves 23. The connecting plate 20 is fixedly disposed on one side of the mounting plate 13. The two fixing plates 21 are respectively fixedly disposed on one end of the first sliding rod 6 and the second sliding rod 10. Each bolt 22 is inserted into one fixing plate 21, and each threaded groove 23 is opened on the connecting plate 20. Each bolt 22 is threadedly connected to one threaded groove 23.

[0049] When shading is required for the fruits and vegetables inside greenhouse 1 under different light intensities, the greenhouse 1 is covered with a shading film of the corresponding intensity. The fixing plate 21 on one side of the sliding rod connected to this shading film is connected to the connecting plate 20. The bolts 22 on the fixing plate 21 are screwed into the corresponding screw grooves 23 on the connecting plate 20. The movement of the mounting plate 13 drives the connecting plate 20 to move, thereby driving the corresponding sliding rod to move, and thus driving the corresponding shading film to cover the greenhouse 1. By switching the connection plate 20 with different fixing plates 21, the switching between the first shading film and the second shading film with different shading intensities can be realized, meeting the different shading needs of different fruits and vegetables, greatly increasing the flexibility and practicality of this device.

[0050] like Figures 1-10 As shown, each first slide rail 7 has a first slide groove 24 inside, and each second slide rail 11 has a second slide groove 25 inside. Two first slide sleeves 26 are rotatably provided at both ends of the first sliding rod 6, and two second slide sleeves 27 are rotatably provided at both ends of the second sliding rod 1. Each first slide sleeve 26 is slidably connected to a first slide groove 24, and each second slide sleeve 27 is slidably connected to a second slide groove 25.

[0051] When the rotating component drives the sliding rod to slide inside the corresponding slide rail, the sliding rod will simultaneously drive the sliding sleeve on the outer wall surface to move together. The sliding sleeve, which is rotatably connected to the sliding rod, slides in the groove opened in the slide rail, reducing the friction of the sliding rod sliding in the slide rail. This helps to reduce the wear of both components, extend the service life of the device, improve the maintenance efficiency of the device, and reduce maintenance costs.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
