Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice seedling technology, and in particular to an anti-lodging device for rice seedlings. Background Technology
[0002] In rice cultivation, lodging prevention during the seedling stage plays a crucial role in ensuring the healthy growth and final yield of rice. However, traditional methods for preventing lodging in rice seedlings have many shortcomings, causing numerous problems for rice farmers.
[0003] In the early days, some rice farmers used manual stalks to tie the rice plants to prevent lodging. This method was not only labor-intensive and time-consuming, but also extremely inefficient. Furthermore, the slightest mistake during the tying process could damage the rice seedlings, affecting their normal growth. As the scale of rice cultivation continued to expand, this method became increasingly inadequate to meet the demand.
[0004] Some simple lodging prevention devices, such as fixed-height fence-like protective structures, can provide some protection, but they cannot adapt to the height changes of rice at different growth stages. As rice grows, its height continuously increases, and the protective height applicable in the early stages becomes ineffective in the later stages, failing to provide continuous lodging protection for the rice.
[0005] Existing adjustable lodging prevention devices have serious flaws in their adjustment methods. For example, some devices have complex adjustment structures, making them difficult to operate. Rice farmers need to spend a lot of time and energy learning and operating them, which is a huge burden during the busy farming season. Moreover, these complex adjustment structures are prone to failure after frequent use, resulting in high maintenance costs and difficulties, thus reducing the practicality of the devices.
[0006] Furthermore, traditional anti-lodging devices also have problems with soil stabilization. Many devices rely solely on simple straight rods inserted into the soil, which are not securely fixed in the face of severe weather such as wind and rain, and are prone to displacement, significantly reducing their anti-lodging effectiveness. At the same time, the components of these devices are easily damaged during long-term use due to friction, wind, and sun exposure, resulting in a shorter lifespan and increased planting costs.
[0007] With the advancement of agricultural modernization, rice cultivation is developing towards large-scale and high-efficiency operations, which places higher demands on anti-lodging devices for rice seedlings. Developing an anti-lodging device that is easy to operate, adaptable to different growth stages of rice, and is stable and durable has become an important problem that urgently needs to be solved in the current rice cultivation field. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides an anti-lodging device for rice seedling cultivation, which solves the technical problems of traditional anti-lodging methods for rice seedlings, such as high labor costs, inability to adapt to height changes at different growth stages of rice, complex adjustment methods prone to failure, insecure soil fixation, and easy damage to device components.
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A lodging prevention device for rice seedling cultivation includes a main rod and an insertion rod. The main rod has two vertical placement slots, each with a set of equidistant T-shaped grooves on its wall. A sliding strip is placed in each placement slot. A baffle plate is fixed to the middle part of the insertion rod, and the baffle plate has four annularly arranged slots. A guide rail is fixed at the opening of each slot, and a collar is fixed on each guide rail. An expanding rod is movably fitted inside each collar. A set of equidistant T-shaped locking blocks is fixed to the surface of the sliding strip facing the T-shaped grooves.
[0011] Preferably, each slide bar has a set of retaining rings fixed on its side, each slide bar has a connecting piece fixedly connected to its upper end, and each connecting piece has a positioning screw threaded onto it.
[0012] Preferably, the upper surface of the main rod has two threaded holes, and the positioning screws on the two connecting pieces are respectively threaded into the two threaded holes.
[0013] Preferably, each collar has a rubber pad fixed to its inner wall.
[0014] Preferably, the lower end of each expansion rod is a tapered end, and the upper end of each expansion rod is fixedly connected to a stop block.
[0015] Preferably, the upper ends of the four guide rails are fixedly connected to the upper end of the insertion rod, and the slot diameter is the same as the rod diameter of the expansion rod.
[0016] Preferably, the lower end of the insertion rod is a tapered end, and the upper end of the insertion rod is fixedly connected to the lower end of the main rod.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] I. Through the unique T-shaped groove and sliding strip design on the main pole, the position of the sliding strip can be conveniently and quickly adjusted according to the height of the rice at different growth stages, thereby flexibly changing the height of the elastic net. During the rice growth process, the end of the elastic net can be hung on the corresponding height ring at any time. When wind and rain strike, the elastic net can promptly confine the rice plants within a safe range, effectively preventing lodging and providing continuous and efficient support and protection for the normal growth of rice. This significantly improves the rice's resistance to lodging under severe weather conditions and ensures rice yield.
[0019] Second, the tapered end of the insertion rod facilitates easy insertion into the soil, while the central baffle precisely controls the insertion depth, preventing excessive insertion from affecting the device's performance and enhancing its stability in the soil. After the adjustable expansion rod is pulled out of the slot, its tapered end inserts into the surrounding soil, significantly increasing the contact area and gripping force between the device and the soil, ensuring the entire device is firmly rooted and resists external displacement. Simultaneously, the rubber pads on the inner wall of the collar not only increase the stability of the expansion rod after adjustment but also reduce wear between components, extending the overall service life of the device, lowering long-term operating costs, and providing durable and reliable lodging protection during the rice seedling stage.

[0026] This application provides an anti-lodging device for rice seedling cultivation, which effectively solves the technical problems of traditional anti-lodging methods for rice seedlings, such as high labor costs, inability to adapt to height changes at different growth stages of rice, complex adjustment methods prone to failure, unstable soil fixation, and easy damage to device components.
[0027] Example
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the overall technical solution in this application embodiment is as follows:
[0029] To address the problems existing in the prior art, this utility model provides an anti-lodging device for rice seedling cultivation, including a main rod 1 and an insertion rod 3. The main rod 1 has two vertical placement slots 4, and each placement slot 4 has a set of equidistant T-shaped sliding grooves 5 on its wall. Each placement slot 4 contains a sliding strip 6. The middle part of the insertion rod 3 is fixed with a baffle 15, and the baffle 15 has four ring-shaped slots 14. Each slot 14 has a guide rail 17 fixed at its opening, and each guide rail 17 has a collar 16 fixed on it. Each collar 16 contains an outwardly expanding rod 13. The sliding strip 6 has a set of equidistant T-shaped locking blocks 11 fixed on its surface facing the T-shaped sliding grooves 5.
[0030] Each slider 6 has a set of retaining rings 7 fixed to its side, and a connecting piece 8 fixedly connected to the upper end of each slider 6. Each connecting piece 8 has a positioning screw 9 threadedly fitted onto it. The upper surface of the main rod 1 has two threaded holes 10. The positioning screws 9 on the two connecting pieces 8 are threadedly fitted into the two threaded holes 10 respectively. When installing the device, first place the slider 6 into the mounting groove 4 on the main rod 1. The T-shaped retaining block 11 on the slider 6 cooperates with the T-shaped sliding groove 5 on the groove wall of the mounting groove 4. The T-shaped structure design allows the slider 6 to slide laterally in the mounting groove 4 without disengaging from it, ensuring the stability and flexibility of the slider 6 installed on the main rod 1. This sliding connection method allows for rapid movement of the slider 6, creating a gap between the retaining ring 7 and the main rod 1, facilitating the attachment of the elastic net 2. The slider 6 is fixed in position using the positioning screw 9. Two threaded holes 10 are provided on the upper surface of the main rod 1. The positioning screw 9 is screwed into the corresponding threaded holes 10. By tightening the positioning screw 9, the connecting piece 8 is tightly fitted against the upper surface of the main rod 1, thereby firmly fixing the slider 6 to the main rod 1. This ensures that the slider 6 will not slide arbitrarily due to external forces or other factors during rice growth, maintaining the stability of the anti-lodging device.
[0031] Each collar 16 has a rubber pad fixed to its inner wall. The lower end of each expansion rod 13 is tapered, and the upper end of each expansion rod 13 is fixedly connected to a stop block 12. The upper ends of the four guide rails 17 are fixedly connected to the upper end of the insertion rod 3. The groove diameter of the slot 14 is the same as the diameter of the expansion rod 13. The lower end of the insertion rod 3 is tapered, and the upper end of the insertion rod 3 is fixedly connected to the lower end of the main rod 1. An elastic net 2 is hung between two adjacent main rods 1 through a retaining ring 7. The tapered lower end of the insertion rod 3 facilitates its insertion into the soil of the rice seedling field. A baffle 15 is fixed to the middle part of the insertion rod 3. The baffle 15 limits the insertion depth to prevent the insertion rod 3 from being inserted too deeply and affecting the overall performance of the device. It also increases the stability of the device in the soil. The baffle 15 has four ring-shaped slots 14. A guide rail 17 is fixed at the opening of each slot 14. The expansion rod 13 is movably fitted inside the collar 16 fixed on the guide rail 17. The upper ends of the four guide rails 17 are fixedly connected to the upper end of the insertion rod 3, ensuring the stability of the entire structure. The groove diameter of the slot 14 is the same as the rod diameter of the expansion rod 13, allowing the expansion rod 13 to slide smoothly within the slot 14 and maintain a relatively stable position. The lower end of the expansion rod 13 is tapered, facilitating insertion into the soil, and the upper end is fixedly connected to a stop block 12 to prevent the expansion rod 13 from coming out of the collar 16. Each collar 16 has a rubber pad fixed to its inner wall, which increases the friction between the collar 16 and the expansion rod 13, making it less likely for the expansion rod 13 to slide freely after being adjusted to the appropriate position; on the other hand, the rubber pad reduces wear between the expansion rod 13 and the collar 16, extending the service life of the device.
[0032] Working principle:
[0033] During installation, the slider 6 is first placed into the mounting slot 4 on the main rod 1. The T-shaped locking block 11 on the slider 6 cooperates with the T-shaped sliding groove 5 on the groove wall of the mounting slot 4. The T-shaped structure design allows the slider 6 to slide laterally within the mounting slot 4 without detaching from it, ensuring the stability and flexibility of the slider 6 on the main rod 1. Through this sliding connection method, the slider 6 can be moved quickly to create a gap between the retaining ring 7 and the main rod 1, facilitating the attachment of the elastic net 2. The positioning screw 9 is used to fix the position of the slider 6.
[0034] Two threaded holes 10 are provided on the upper surface of the main rod 1. The positioning screw 9 is screwed into the corresponding threaded hole 10. By tightening the positioning screw 9, the connecting piece 8 is tightly attached to the upper surface of the main rod 1, thereby firmly fixing the slide bar 6 to the main rod 1. This ensures that the slide bar 6 will not slide arbitrarily due to external forces or other factors during the rice growth process, thus maintaining the stability of the anti-lodging device.
[0035] The lower end of the insertion rod 3 is tapered, facilitating its insertion into the soil of the rice seedling bed. A baffle 15 is fixed to the middle part of the insertion rod 3, limiting the insertion depth to prevent excessive insertion and maintain the overall performance of the device, while also increasing its stability in the soil. The baffle 15 has four annularly arranged slots 14, each with a guide rail 17 fixed at its opening. An expansion rod 13 is movably fitted within a collar 16 fixed to the guide rail 17. The upper ends of all four guide rails 17 are fixedly connected to the upper end of the insertion rod 3, ensuring the stability of the entire structure. The diameter of the slot 14 is the same as the diameter of the expansion rod 13, allowing the expansion rod 13 to slide smoothly within the slot 14 and maintain a relatively stable position. The lower end of the expansion rod 13 is tapered for easy insertion into the soil, while a stop block 12 is fixedly connected to its upper end to prevent the expansion rod 13 from detaching from the collar 16. Each collar 16 has a rubber pad fixed to its inner wall. On the one hand, the friction between the collar 16 and the outer expansion rod 13 is increased, making it less likely for the outer expansion rod 13 to slide freely after being adjusted to the appropriate position. On the other hand, the rubber pad can reduce the wear between the outer expansion rod 13 and the collar 16, and extend the service life of the device.
[0036] When installing the entire device in the seedling field, first insert the insertion rod 3 into the soil. Since the lower end of the insertion rod 3 is tapered, it can penetrate the soil relatively easily. As the insertion rod 3 is gradually inserted, the baffle 15 contacts the soil surface and prevents the insertion rod 3 from going any deeper, ensuring a suitable insertion depth. At this point, depending on the looseness of the soil and the actual conditions of the rice planting area, insert the expansion rod 13. Pull the expansion rod 13 out of the slot 14 along the guide rail 17. The tapered end of the expansion rod 13 inserts into the surrounding soil. Through the outward expansion of the expansion rod 13, the contact area and gripping force between the device and the soil are increased, making the entire anti-lodging device more stable in the soil and less prone to displacement due to external forces such as wind.
[0037] During the rice growth process, the ends of the elastic net 2 are hung on the clips 7 at different heights according to the growth height of the rice. The elastic net 2 is around the rice plants. When encountering severe weather such as wind and rain that may cause the rice to lodging, the elastic net 2 restricts the rice plants within a certain range to prevent them from lodging due to external forces, thus providing stable support and protection for the normal growth of rice.
[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
