Description

Technical Field

[0001] This utility model relates to the technical field of plant cultivation auxiliary tools, and in particular to a plant seedling anti-lodging fixing frame. Background Technology

[0002] During the cultivation of plant seedlings, seedlings are susceptible to lodging due to their underdeveloped root systems and slender stems. This can be caused by factors such as wind, rain, or human impact, which can not only damage the seedling's growth pattern but also lead to root damage, hinder photosynthesis, and in severe cases, even seedling death, significantly reducing the survival rate of seedlings. Therefore, plant seedling anti-lodging fixing frames are needed to secure them.

[0003] The existing single-point support design of the fixing frame essentially concentrates all the external forces on the seedlings onto a single support point. When the seedlings tilt slightly due to factors such as phototropism and wind, the support components will misalign with the stem, resulting in localized stress concentration. This not only loses effective support but may also exacerbate seedling lodging or stem bending. Therefore, we propose a plant seedling anti-lodging fixing frame. Utility Model Content

[0004] The purpose of this utility model is to provide a plant seedling anti-lodging fixing frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plant seedling anti-lodging fixing frame, comprising a rotating fixing mechanism and an anti-lodging mechanism disposed around it. The anti-lodging mechanism includes a ring frame, with four sets of threaded columns fixedly installed in the middle of the ring frame. Multiple sets of sliding frames are slidably connected to the outer walls of the four sets of threaded columns. Limiting nuts are threadedly connected to the upper and lower ends of the four sets of threaded columns at the multiple sets of sliding frames. The sliding frames are connected to threaded rotating rods through threaded sleeves. The threaded rotating rods are connected to arc-shaped frames through collars. Multiple sets of support members are fixedly installed on the inner wall of the arc-shaped frames.

[0006] As a preferred embodiment, multiple sets of second grounding cones are fixedly installed at the bottom of the ring frame, and the four sets of threaded columns are equidistantly distributed along the circumference of the ring frame.

[0007] As a preferred embodiment, one end of the threaded sleeve is fixedly installed on the outer wall of the sliding frame, and the threaded rod is threadedly connected to the inside of the threaded sleeve.

[0008] As a preferred embodiment, the arc-shaped frame is fixedly mounted on the collar, and the collar is sleeved on the outer end of the threaded rotating rod.

[0009] As a preferred embodiment, the rotating fixing mechanism includes a fixing column, with multiple sets of first ground-piercing cones fixedly installed at the bottom of the fixing column, and a connecting frame rotatably connected to the outer wall of the fixing column.

[0010] As a preferred embodiment, the fixed column is internally threaded with a threaded rod, and a rotating frame is fixedly installed at the upper end of the threaded rod. Four sets of fixing rods are equidistantly provided on the upper circumferential surface of the rotating frame, and the internal threads of the fixing rods are connected with limit bolts.

[0011] As a preferred embodiment, a stabilizing frame is rotatably connected to the outer wall of the fixed rod, and an extension frame is inserted into the inside of the stabilizing frame, with the extension frame being fixedly connected to the ring frame.

[0012] The technical effects and advantages of this utility model are as follows: 1. Through the anti-tipping mechanism, multiple sliding frames slidably connected to the outer wall of the threaded column, combined with the limiting nuts at both ends, allow for free vertical adjustment of the sliding frames. The position of the sliding frames can be adjusted according to the different growth heights of the seedlings to match the support needs of the seedlings. Multiple supports are provided. At the same time, the threaded rod connected to the sliding frame through the threaded sleeve can be rotated to adjust the length, thereby moving the arc-shaped frame closer to or away from the seedling. Multiple sets of support components can form flexible contact with the seedling stems, providing support for the seedlings while avoiding damage to the seedling stems. With the addition of the collar for fine adjustment of the angle of the arc-shaped frame, it can adapt to seedling varieties of different thicknesses and growth forms. The same fixed frame can be used continuously throughout the entire growth cycle of the seedlings, improving the utilization rate of the equipment. 2. Through the set rotating fixing mechanism, after the first ground-piercing cone penetrates into the soil, it provides a central anchoring effect for the fixing frame. The threaded rod connected inside the fixing column, together with the upper rotating frame, can realize the vertical raising and lowering of the threaded rod through rotation operation, thereby driving the rotating frame and the fixing rod above to adjust the height synchronously. It can adjust the overall height of the fixing frame according to the terrain difference of the planting area to ensure that the anti-tipping mechanism is adapted to the growth height of the seedlings. It can also gradually increase the support height as the seedlings grow, avoiding the restriction of seedling growth caused by the support position being too low. At the same time, the limiting bolt inside the fixing rod can fix the rotation angle of the stabilizing frame. The extension frame can be extended inside the stabilizing frame, which makes it convenient for growers to adjust the support angle of the stabilizing frame according to the distribution density and growth direction of the seedlings, adapting to the needs of different planting spacing and layout.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 A seedling anti-lodging fixing frame includes a rotating fixing mechanism 1 and an anti-lodging mechanism 2 arranged around it. The anti-lodging mechanism 2 includes a ring frame 201. Four sets of threaded columns 202 are fixedly installed in the middle of the ring frame 201. Multiple sets of sliding frames 204 are slidably connected to the outer walls of the four sets of threaded columns 202. Limiting nuts 205 are threadedly connected to the upper and lower ends of the four sets of threaded columns 202 at the multiple sets of sliding frames 204. The sliding frames 204 are connected to threaded rotating rods 207 through threaded sleeves 206. The threaded rotating rods 207 are connected to arc-shaped frames 209 through collars 208. Multiple sets of support members 210 are fixedly installed on the inner wall of the arc-shaped frames 209.

[0017] Four sets of threaded posts 202 are fixedly installed in the middle of the ring frame 201. The outer wall of the threaded posts 202 is machined with external threads, which serve as a carrier for the sliding frame 204 to slide and be fixed. The four sets ensure that the sliding frame 204 is evenly stressed after adjustment. The center of the sliding frame 204 has a through hole that matches the threaded posts 202, allowing it to slide up and down along the outer wall of the threaded posts 202. The inner wall of the limiting nut 205 is machined with internal threads that match the external threads of the threaded posts 202. After tightening, the sliding frame 204 can be fixed in position by friction. In actual use, the sliding frame 204 can slide to the corresponding height according to the height of the seedling, and then be clamped and fixed by the upper and lower sets of limiting nuts 205 to meet the support height requirements of the seedling at different growth stages. The support component 210 is made of elastic materials such as rubber blocks and soft plastic protrusions, and is fixed to the inner wall of the arc frame 209. When it comes into contact with the seedling stem, it can avoid rigid friction damage. At the same time, it fits the stem surface through elastic deformation to ensure stable support, which is in line with the actual growth characteristics of seedling stems that are fragile and need flexible protection.

[0018] Multiple sets of second ground-holding cones 203 are fixedly installed at the bottom of the ring frame 201, and four sets of threaded columns 202 are equidistantly distributed along the circumference of the ring frame 201.

[0019] The second ground cone 203 is a cone-shaped metal part. When planting, it is inserted into the soil to fix the ring frame 201 to the ground, preventing the ring frame 201 from shifting due to wind or water erosion. This solves the problem that the traditional ring frame 201 is easy to move when placed on the ground, and is especially suitable for soft soil, potted plant edges and other easy-to-slip scenarios.

[0020] One end of the threaded sleeve 206 is fixedly installed on the outer wall of the sliding frame 204, and the threaded rod 207 is threadedly connected to the inside of the threaded sleeve 206.

[0021] The threaded rod 207 can smoothly extend and retract along the axis of the threaded sleeve 206. In actual operation, no additional tools are required; it can be adjusted by manual rotation, which meets the actual needs of planting personnel for convenient operation. At the same time, the threaded connection has self-locking properties, so the threaded rod 207 is not easy to loosen after adjustment, ensuring stable support.

[0022] The arc-shaped frame 209 is fixedly installed on the collar 208, and the collar 208 is sleeved on the outer end of the threaded rotating rod 207.

[0023] The collar 208 is a ring structure. One end of the arc frame 209 is welded or bolted to the outer wall of the collar 208. After fixing, the arc direction of the arc frame 209 faces the seedling side, ensuring that the arc frame 209 can accurately fit the stem after the collar 208 is fitted with the threaded rotating rod 207.

[0024] Specifically, the multiple sliding frames 204 slidably connected to the outer wall of the threaded column 202, combined with the limiting nuts 205 at its upper and lower ends, allow for free vertical adjustment of the sliding frames 204. The position of the sliding frames 204 can be adjusted according to the different growth heights of the seedlings to match their support needs. Simultaneously, the threaded rotating rod 207 connected to the sliding frame 204 via the threaded sleeve 206 can be rotated to adjust its length, thereby moving the arc-shaped frame 209 closer to or further away from the seedling. The multiple support components 210 can form flexible contact with the seedling stem, providing support while avoiding damage to the stem. Combined with the fine-tuning of the angle of the arc-shaped frame 209 by the collar 208, it can adapt to seedling varieties of different thicknesses and growth forms, enabling continuous use of the same fixed frame throughout the entire seedling growth cycle and improving equipment utilization.

[0025] Please see the appendix Figure 1 - Appendix Figure 3 The rotating fixing mechanism 1 includes a fixing column 101, with multiple sets of first ground-piercing cones 102 fixedly installed at the bottom of the fixing column 101, and a connecting frame 103 rotatably connected to the outer wall of the fixing column 101.

[0026] The connecting bracket 103 is used to connect adjacent fixed brackets to form a whole.

[0027] The fixed column 101 is internally threaded with a threaded rod 104. A rotating frame 105 is fixedly installed on the upper end of the threaded rod 104. Four sets of fixed rods 106 are equidistantly opened on the upper circumferential surface of the rotating frame 105. The fixed rods 106 are internally threaded with limit bolts 107.

[0028] The fixing rod 106 has a screw hole inside that matches the limiting bolt 107, which is used to fix the rotating frame 105.

[0029] A stabilizing frame 108 is rotatably connected to the outer wall of the fixed rod 106, and an extension frame 109 is inserted into the inside of the stabilizing frame 108. The extension frame 109 is fixedly connected to the ring frame 201.

[0030] The connection between the extension frame 109 and the stabilizer frame 108 has a certain damping, and the two will not move automatically to each other after adjustment.

[0031] Specifically, after the first ground-piercing cone 102 penetrates the soil, it provides a central anchoring function for the fixing frame. The threaded rod 104 connected internally to the fixing column 101, together with the upper rotating frame 105, can be vertically raised and lowered by rotation, thereby driving the rotating frame 105 and the fixing rod 106 above to adjust their height synchronously. This can adjust the overall height of the fixing frame according to the terrain differences of the planting area, ensuring that the anti-tipping mechanism 2 is adapted to the growth height of the seedlings. It can also gradually increase the support height as the seedlings grow, avoiding the restriction of seedling growth caused by the support position being too low. At the same time, the limiting bolt 107 inside the fixing rod 106 can fix the rotation angle of the stabilizing frame 108. The extension frame 109 can be extended inside the stabilizing frame 108, which makes it convenient for growers to adjust the support angle of the stabilizing frame 108 according to the seedling distribution density and growth direction, adapting to the needs of different planting spacing and layout.

[0032] The working principle of this utility model is as follows: This utility model is a seedling anti-lodging fixing frame. The fixing column 101 of the rotating fixing mechanism 1 is placed vertically next to the seedling. By manually pressing or tapping the top of the fixing column 101, the multiple sets of first ground-piercing cones 102 at the bottom of the fixing column 101 are driven into the soil, thus anchoring the bottom of the fixing column 101 and preventing it from tipping over or shifting during subsequent use.

[0033] Based on the current seedling height, rotate the threaded rod 104 connected to the internal thread of the fixed column 101. When rotating the threaded rod 104 clockwise, the threaded rod 104 extends upward along the axial direction of the fixed column 101; when rotating counterclockwise, it retracts downward until the height of the rotating frame 105 fixed at the upper end of the threaded rod 104 matches the position of the upper part of the seedling stem, and then stop rotating the threaded rod 104.

[0034] Rotate the four sets of fixed rods 106 that are equidistantly distributed around the upper circumference of the rotating frame 105 and connect them to the outer wall of the stabilizing frame 108. Adjust the stabilizing frame 108 to an angle that tilts outward. At this time, do not tighten the limiting bolts 107 inside the fixed rods 106 to reserve adjustment space for the subsequent connection of the anti-tipping mechanism 2.

[0035] The extension frame 109 inserted inside the tension stabilizing frame 108 is stretched until the ring frame 201 is directly above the seedling. Then, the top of the ring frame 201 is pressed down, allowing the multiple sets of second ground-holding cones 203 at the bottom of the ring frame 201 to insert into the soil, completing the initial fixation of the ring frame 201 and forming an outer protective frame around the seedling. Then, the limiting bolts 107 inside the fixing rod 106 are tightened, so that the ends of the limiting bolts 107 press against the outer wall of the stabilizing frame 108, fixing the angle of the stabilizing frame 108, realizing the rigid connection between the rotation fixing mechanism 1 and the anti-tipping mechanism 2, forming a complete support frame.

[0036] Observe the four sets of threaded columns 202 fixed in the middle of the ring frame 201, loosen the limiting nuts 205 at the upper and lower ends of the sliding frame 204 on the outer wall of the threaded column 202, and push the sliding frame 204 to slide up and down along the axis of the threaded column 202 until the height of the sliding frame 204 corresponds completely to the position of the stem that the seedling needs to support; then tighten the limiting nuts 205 at the upper and lower ends of the sliding frame 204 respectively, and clamp the sliding frame 204 with the thread friction between the limiting nuts 205 and the threaded column 202 to fix its position.

[0037] The threaded rod 207 inside the threaded sleeve 206 fixed to the outer wall of the rotating sliding frame 204 extends towards the seedling along the axial direction of the threaded sleeve 206 when the threaded rod 207 is rotated clockwise; when rotated counterclockwise, it retracts outward until the arc-shaped frame 209 connected to the outer end collar 208 of the threaded rod 207 approaches the seedling stem, at which point the rotation of the threaded rod 207 stops.

[0038] Rotating the collar 208 fitted to the outer end of the threaded rod 207 causes the arc-shaped frame 209 fixed on the collar 208 to rotate synchronously, so that the inner wall of the arc-shaped frame 209 is in contact with the surface of the seedling stem; at this time, the multiple sets of support members 210 on the inner wall of the arc-shaped frame 209 are in flexible contact with the stem, which not only provides support but also avoids squeezing and damaging the stem, thus completing the installation and debugging of the entire fixing frame.

[0039] As the seedling grows taller, loosen the limiting nut 205 on the sliding frame 204 of the threaded column 202, push the sliding frame 204 upward to the new support height, and then tighten the limiting nut 205 to ensure that the support position always matches the upper part of the seedling stem. If the seedling stem thickens, rotate the threaded rod 207 counterclockwise to slightly move the arc frame 209 outward to avoid excessive compression of the stem by the support 210; conversely, if the stem grows off-center, the angle of the arc frame 209 can be adjusted by rotating the collar 208 to maintain the support fit.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
