[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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 a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example
[0032] Please refer to Figures 1 to 4 This utility model provides a field support to improve the distribution of assimilates in tropical soybeans, which aims to solve the problem that tropical soybeans are prone to lodging in the middle and late stages of growth due to their thin and long stems, which in turn hinders the effective distribution of photosynthetic products to the pods.
[0033] like Figure 1 and Figure 2As shown, a field support structure for improving assimilate distribution in tropical soybeans includes a fixed pointed pile 1, an auxiliary support foot 2, and a column 3. The auxiliary support foot 2 is fixedly connected to the top of the fixed pointed pile 1, and the column 3 is vertically fixedly connected above the fixed pointed pile 1 and the auxiliary support foot 2. The fixed pointed pile 1 is used to insert deep into the soil to provide basic anchoring force and prevent the device from tipping over. The auxiliary support foot 2 is used to increase the contact area with the ground to distribute pressure and assist the fixed pointed pile 1 in forming a stable installation base. The column 3 serves as the main load-bearing component for installing subsequent functional components. A telescopic tube 15 is slidably connected to the outer wall of the column 3. An adjustment hole 16 is opened on the left side of the telescopic tube 15, and an adjustment bolt 13 is threaded into the adjustment hole 16. The telescopic tube 15 can slide up and down along the axis of the column 3 to adapt to the height requirements of soybean plants at different growth stages. The adjustment bolt 13 is screwed into the adjustment hole 16 and abuts against it. The telescopic tube 15 is locked in position on the outer wall of the column 3. A fixing buckle 14 is fixedly connected to the outer wall of the telescopic tube 15. The fixing buckle 14 is used to provide support and positioning for the upper and middle stems of the soybean plant. At the same time, a collar 6 is rotatably connected to the outer side of the column 3. A fastening hole 17 is opened on the side of the collar 6. A fixing bolt 7 is screwed into the fastening hole 17. A rotating adjustment buckle 4 is fixedly connected to the outer wall of the collar 6 through a connecting rod 5. The rotating adjustment buckle 4 is used to provide support and positioning for the lower and middle stems of the soybean plant. The fixing buckle 14 and the rotating adjustment buckle 4 form an upper and lower graded support structure in space to distribute the force on the stem. In addition, a through hole 10 is opened on the side wall of the column 3. A connecting rod 9 slides through the through hole 10. The two ends of the connecting rod 9 are respectively threaded to a threaded joint 8 and a sleeve 11. The connecting rod 9 is used to connect adjacent support devices laterally to enhance the overall wind resistance.
[0034] Please refer to Figure 2 , Figure 3 and Figure 4The telescopic tube 15 is designed as a hollow cylindrical structure and is slidably fitted onto the outer cylindrical surface of the column 3 in a coaxial manner. A precise sliding fit is maintained between the inner wall of the telescopic tube 15 and the outer wall of the column 3. An adjustment hole 16 is radially inserted into the side wall of the telescopic tube 15. An adjustment bolt 13 is installed inside the adjustment hole 16 via an external thread. The operator applies positive pressure to the surface of the column 3 by tightening the adjustment bolt 13, thereby utilizing friction to achieve stable self-locking of the telescopic tube 15 at any axial height position on the column 3. A fixing buckle 14 is fixedly connected to the outer side of the telescopic tube 15 by welding or integral molding. The fixing buckle 14 rises and falls synchronously with the telescopic tube 15 to dynamically adapt to changes in the elongation of the soybean internodes. A collar 6 is provided in the lower region of the column 3, and the collar 6 is rotatable. Surrounding the outer periphery of the column 3, fastening holes 17 are radially arranged on the side wall of the collar 6. The fixing bolts 7 are screwed into the fastening holes 17 and pressed against the outer wall of the column 3, thereby locking the collar 6 at a specific angle. One end of the connecting rod 5 is vertically fixed to the outer wall of the collar 6, and the other end of the connecting rod 5 is fixedly connected to the rotating adjustment buckle 4, so that the rotating adjustment buckle 4 can be adjusted circumferentially with the column 3 as the axis, accurately aligning with the offset direction of soybean stalk growth. In addition, the connecting rod 9 passes horizontally through the through hole 10 opened in the middle of the column 3. The threaded joint 8 at the end of the connecting rod 9 and the internal thread 12 formed by tapping inside the sleeve 11 constitute a helical transmission pair. Rotating the sleeve 11 can drive the connecting rod 9 to produce a small axial displacement, thereby finely adjusting the transverse connection span and eliminating installation gaps, ensuring the rigidity and stability of the overall support network.
[0035] In a preferred embodiment, in order to ensure the stability of the support structure and the flexibility of adjustment, a through hole 10 is provided on the side wall of the column 3, and the connecting rod 9 is slidably connected to the inside of the through hole 10. The setting of the connecting rod 9 allows a single support to extend laterally or connect with the support. The inner wall of the through hole 10 and the outer wall of the connecting rod 9 maintain a sliding fit relationship. This sliding fit allows the connecting rod 9 to move freely in the horizontal direction for initial positioning and connection.
[0036] As another preferred embodiment, in order to achieve rigid locking between the collar 6 and the column 3, after the fixing bolt 7 is screwed into the fastening hole 17, the end of the fixing bolt 7 abuts against the outer wall of the column 3, and the rotation angle of the collar 6 is locked by radial tightening friction. The fastening hole 17 is opened on the side wall of the collar 6 and is positioned opposite to the outer wall of the column 3 to ensure that the fixing bolt 7 can effectively apply locking force. When the fixing bolt 7 is not tightened, the collar 6 can rotate around the column 3 to achieve circumferential fine adjustment of the support angle of the rotation adjustment buckle 4.
[0037] In another preferred embodiment, in order to reliably fix the telescopic tube 15, after the adjusting bolt 13 is screwed into the adjusting hole 16, the end of the adjusting bolt 13 abuts against the outer wall of the column 3, and the axial height of the telescopic tube 15 relative to the column 3 is locked by friction or deformation, so as to ensure that the support height obtained by the soybean plant at different growth stages is stable. The position of the adjusting hole 16 needs to match the thread of the adjusting bolt 13 to ensure smooth screwing.
[0038] As another preferred embodiment, in order to adapt to the planting row spacing and plant growth orientation of soybeans, the collar 6 is rotatably connected to the outside of the column 3 and located below the perforation 10. This positional relationship allows the rotating adjustment buckle 4 to be in a lower position, which can support the middle and lower stems of the soybean plant without interfering with the lateral connection function of the connecting rod 9.
[0039] In another preferred embodiment, to enhance the strength and adjustability of the lateral connection, the connecting rod 9 laterally penetrates the through hole 10 of the column 3, and the sleeve 11 is located on the outside of the column 3. The two ends of the connecting rod 9 are connected to the sleeve 11 through the threaded joint 8 and the internal thread 12. The sleeve 11 serves as the end extension of the connecting rod 9, and the internal thread 12 is adapted to the threaded joint 8 of the connecting rod 9. By rotating the sleeve 11, the connecting rod 9 can be driven to extend and retract axially, thereby achieving fine adjustment of the connection length.
[0040] In another preferred embodiment, in order to provide effective graded support for soybean plants, the fixed buckle 14 is fixedly connected to the outer wall of the telescopic tube 15, and the rotating adjustment buckle 4 is connected to the collar 6 through the connecting rod 5. The fixed buckle 14 corresponds to the upper and middle stems of the soybean plant, and the rotating adjustment buckle 4 corresponds to the lower and middle stems of the soybean plant. The two form an upper and lower graded support structure, which can be independently adjusted according to the different heights and growth angles of the soybean plants. This dual buckle collaborative design effectively ensures the overall stability of the plant.
[0041] As another preferred embodiment, the threaded joint 8 of the connecting rod 9 is screwed into the internal thread 12 of the sleeve 11. The extension or retraction of the connecting rod 9 is achieved by rotating the sleeve 11, thereby achieving the purpose of fine-tuning the length of the connecting rod 9. This threaded fit structure provides a precise means of tension adjustment for transverse connections and can eliminate the cumulative tolerance when multiple connecting rods 9 are used together.
[0042] Working principle: First, the device is installed and fixed. The fixed stake 1 is vertically inserted into the soil in the field. The device is stably anchored by the friction between the fixed stake 1 and the soil and the contact area provided by the auxiliary support foot 2, ensuring that the structure can adapt to the complex outdoor ground environment. The column 3 is installed vertically above the fixed stake 1 and the auxiliary support foot 2 as the main support.
[0043] Regarding the height adjustment, the operator slides the telescopic tube 15 on the outer wall of the column 3 upwards or downwards according to the height of the soybean plant at different growth stages, and adjusts the fixing buckle 14 to the height corresponding to the upper part of the soybean plant stem. After the height is adjusted to the correct position, the operator aligns the adjustment hole 16 on the telescopic tube 15 and screws in the adjustment bolt 13. The end of the adjustment bolt 13 abuts against the outer wall of the column 3, and the telescopic tube 15 and the column 3 are rigidly locked by friction or tightening force, ensuring that the support height is stable and there will be no axial displacement. The setting of the adjustment bolt 13 allows the telescopic tube 15 to be adjusted to any position along the axial direction and locked quickly.
[0044] Regarding the support angle adjustment, the collar 6 is rotatably connected to the outside of the column 3. The operator manually rotates the collar 6, thereby driving the rotary adjustment buckle 4 connected by the connecting rod 5 to adjust the angle around the column 3 to adapt to the growth direction of the soybean plants and the planting row spacing. When the rotary adjustment buckle 4 is adjusted to the appropriate support angle, the fixing bolt 7 is screwed in. The end of the fixing bolt 7 abuts against the outer wall of the column 3 to achieve rigid locking between the collar 6 and the column 3, preventing the angle of the rotary adjustment buckle 4 from shifting.
[0045] In terms of lateral connection and fine adjustment, the connecting rod 9 passes through the column 3 laterally through the through hole 10. When it is necessary to connect adjacent support devices or adjust the tension of the lateral support, the operator can rotate the sleeve 11. Due to the threaded fit between the threaded joint 8 and the internal thread 12, rotating the sleeve 11 can drive the connecting rod 9 to produce a slight axial displacement, thereby achieving fine adjustment of the lateral connection length. The installation tolerance can be eliminated by the threaded connection, so that the connecting rod 9 and the column 3 form a rigid connection, which effectively enhances the wind resistance of the entire field support net.
[0046] In terms of tiered support, the fixing buckle 14 is fixedly connected to the outer wall of the telescopic tube 15, corresponding to the upper and middle stem position of the soybean plant. The rotating adjustment buckle 4 is fixed to the outer wall of the collar 6 through the connecting rod 5, corresponding to the lower and middle stem position of the soybean plant. The two form an upper and lower tiered support structure, which can simultaneously provide stable support for the lower and middle and upper parts of the soybean plant stem, effectively dispersing the stress of stem lodging and preventing the plant from lodging. When the soybean plant receives effective support, ventilation and light transmission conditions are improved, ensuring the smooth flow of the stem's vascular tissue, thereby effectively improving the distribution of assimilates from tropical soybeans to the pods and increasing yield.
