Description

Technical Field

[0001] This invention relates to a fixing device, and more particularly to a fixing device for preventing date palm seedlings from lodging during planting, belonging to the field of agricultural and forestry seedling planting and protection technology. Background Technology

[0002] Seedling transplanting is a crucial step in the large-scale artificial cultivation of date palms. However, seedling lodging after transplanting has become a significant factor restricting the survival rate of date palm seedlings. In the early stages of transplanting, the newly formed root system has not yet completed deep rooting and lateral extension, and the root system's ability to hold the entire seedling in place is inherently insufficient, making it extremely easy to cause lodging.

[0003] Currently, the industry commonly uses simple pole fixing methods such as single pole support, tripod support, and four-corner support to prevent date palm seedlings from lodging during planting. By inserting the lower end of the support pole into the soil around the planting hole and connecting the upper end to the seedling stem through binding or clamping, the lodging prevention effect is achieved solely by limiting and constraining the above-ground stem.

[0004] Existing support structures only provide single-point fixation for the above-ground stems of seedlings, failing to fundamentally address the problem of insufficient root holding capacity. When encountering severe weather such as strong winds and heavy rainfall, the external loads such as wind resistance and rain erosion borne by the plant will create a leverage effect through the connection between the support rod and the stem, concentrating the force on the root-stem junction and the underground root system. Continuous and repetitive external disturbances can easily damage the bond between the root system and the surrounding soil, causing the soil around the roots to loosen and the soil aggregate structure to collapse. This significantly reduces the soil's anchoring effect on the root system, further increasing the probability of seedling lodging. In practice, the effect is poor and the applicability is limited.

[0005] To address this issue, a date palm seedling planting and lodging prevention device was designed. Summary of the Invention

[0006] The main objective of this invention is to provide a device for preventing date palm seedlings from lodging during transplanting, in order to solve the problems mentioned in the background art.

[0007] The objective of this invention can be achieved by adopting the following technical solution: A date palm seedling anti-lodging fixing device includes a support post, an installation groove on the side of the support post, and an insertion positioning mechanism at the bottom of the installation groove. The insertion positioning mechanism is used to insert into the soil to fix the support post in place. The bottom of the side of the support is equipped with a bonding mechanism, which is used to compact and anchor the soil around the roots of the seedling. The top of the side of the support is equipped with a binding and connecting mechanism, which is used to support and limit the stem of the date palm seedling; A transmission box is fixed to the top of the support column. An adaptive pressing mechanism is installed inside the transmission box. The power input end of the adaptive pressing mechanism is connected to the binding connection mechanism, and the power output end of the adaptive pressing mechanism is connected to the bonding mechanism. This is used to convert the swaying displacement of the seedling stem into the downward pressure of the bonding mechanism.

The first screw is threaded into the bottom of the mounting groove, the cone block is fixed to the bottom end of the first screw, the anti-detachment block is fixed to the top of the first screw, and the mounting plate is fixed to the bottom of the support column to increase the contact area with the soil and improve the anchoring stability of the support column.

[0009] Preferably, the bonding mechanism includes a crossbar, a nut, a second screw, a mounting block, a first pressure rod, and a second pressure rod. One end of the crossbar is slidably disposed inside the mounting groove. The end of the crossbar located inside the mounting groove is connected to the power output end of the adaptive pressing mechanism.

The mounting block is rotatably mounted on the bottom end of the second screw. First pressure rods are hinged to both sides of the mounting block.

[0010] Preferably, a lever is horizontally slidably mounted on the top end of the second screw, and spherical blocks are fixed at both ends of the lever.

[0011] Preferably, the binding connection mechanism includes a hinge seat, a sleeve, a slide rod, a first positioning bolt, a slip ring, a second positioning bolt, and a strap. The hinge seat is connected to the power input end of the adaptive pressing mechanism. One end of the sleeve is fixedly connected to the hinge seat. The slide rod is slidably inserted into the inside of the sleeve. The first positioning bolt is threaded onto the outer wall of the sleeve to lock the extension and retraction position of the slide rod. The slip ring is slidably fitted onto the outer wall of the slide rod, and the second positioning bolt is threaded onto the outer wall of the slip ring to lock the sliding position of the slip ring. The straps are installed on both sides of the slip ring to bind and fix the stems of the date palm seedlings.

[0012] Preferably, limit rings are symmetrically fixed on both sides of the slide rod away from the sleeve, the strap slides through the inside of the limit ring, and a third positioning bolt is connected between the end of the strap and the outside of the slide ring to lock and fix the end of the strap.

[0013] Preferably, the end of the slide bar away from the sleeve has an arc-shaped groove, and the inside of the arc-shaped groove is provided with a rubber anti-slip pad.

[0014] Preferably, the adaptive pressing mechanism includes an upper transmission rod, a fixed block, a first return spring, a wedge-shaped pressing block, a support block, a V-groove, a second return spring, a lower transmission rod, and a limiting block. The upper transmission rod is horizontally slidably installed inside the transmission box, and one end of the upper transmission rod extends to the outside of the transmission box. The upper transmission rod is connected to the binding connection mechanism. The fixing block is fixed at the middle position of the top of the upper transmission rod, and the first return spring is located between the transmission box and the side of the fixing block, with the two ends of the first return spring abutting against the fixing block and the inner side wall of the transmission box, respectively. The wedge-shaped pressure block is fixed at the bottom end of the upper transmission rod, the support block is located below the wedge-shaped pressure block, the top surface of the support block is provided with a V-shaped groove that matches the wedge-shaped pressure block, and the second return spring is located between the bottom of the support block and the inner bottom of the transmission box. The top end of the lower transmission rod is fixedly connected to the support block, and the bottom end of the lower transmission rod slides into the interior of the mounting groove. A limit block is fixed on the outer side of the bottom end of the lower transmission rod, and the top of the limit block fits against the inner top of the mounting groove to limit the upper limit stroke of the lower transmission rod. The bottom end of the lower transmission rod is connected to the fitting mechanism.

[0015] Preferably, a guide rod is horizontally fixed at the top inner part of the transmission box, the guide rod passes through the first reset spring and the fixing block, and the guide rod is slidably connected to the fixing block.

[0016] Preferably, the top of the transmission box is evenly distributed with anti-slip strips along its length, and the anti-slip strips are parallel to the width direction of the transmission box.

[0017] The beneficial effects of this invention are as follows: This invention provides a date palm seedling anti-lodging fixing device. By setting a binding connection mechanism at the top of the side of the support, the above-ground stem of the date palm seedling can be stably supported and limited. At the same time, a fitting mechanism is set at the bottom of the side of the support to compact and anchor the soil around the seedling roots. The whole device has a dual stabilizing function of stem stabilization and underground root fixation, which improves the holding force of the root system in the early stage of date palm seedling planting. It also avoids the lever force transmission defects of the existing single support structure, avoids the external load being concentrated and transmitted to the root-stem junction, and avoids disturbing the soil around the roots, thus improving the stability of the anti-lodging effect. The binding and connecting mechanism allows for free adjustment of the support angle through the hinge seat. Combined with the telescopic structure of the sleeve and slide rod, and the axial sliding adjustment of the slip ring, it can flexibly adapt to date palm seedlings of different heights and stem diameters. At the same time, the flexible fixing structure of the binding strap replaces the rigid clamping and hard binding of the existing technology. While providing reliable limit to the stem, it effectively avoids mechanical wear and compression damage to the epidermis during the natural thickening of the stem and the shaking of the plant by external forces. This ensures the normal growth of the seedlings during the seedling establishment period and significantly improves the survival rate of date palm seedlings. The bonding mechanism, through the cooperation of the second screw and nut, ensures that the first and second pressure rods are tightly bonded to the ground. At the same time, the first and second pressure rods and the mounting block are hinged, allowing the expansion range of the first and second pressure rods to be adjusted during use, thereby adjusting the contact and pressing area with the ground. This can adapt to the planting needs of date palm seedlings with different planting hole sizes and ensure a uniform compaction effect on the soil around the roots. The adaptive downward pressing mechanism enables mechanical linkage between the binding connection mechanism and the bonding mechanism. Under severe weather conditions such as strong winds and heavy rain, when the seedling stem is impacted by external forces and causes swaying displacement, the linkage structure can convert the swaying amplitude of the stem into the downward pressure gain of the bonding mechanism. The greater the impact on the stem and the more obvious the swaying, the stronger the pressing and anchoring effect of the bonding mechanism on the soil around the roots, forming a dynamic adaptive closed-loop protection. This not only dissipates the external impact load through the flexible buffer of the stem, but also simultaneously strengthens the holding capacity of the soil around the roots, providing dual protection against the risk of lodging caused by severe weather, making it more practical.

[0020] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] Example 1: As Figures 1-9 As shown, this embodiment provides a date palm seedling anti-lodging fixing device, including a support column 1, an installation groove 2 is provided on the side of the support column 1, and an insertion positioning mechanism 3 is provided at the bottom of the installation groove 2. The insertion positioning mechanism 3 is used to insert into the soil to fix the support column 1. The bottom of the side of the support column 1 is provided with a bonding mechanism 4, which is used to compact and anchor the soil around the seedling roots. The top of the side of the support column 1 is provided with a binding and connecting mechanism 6, which is used to support and limit the stem of the date palm seedling; A transmission box 5 is fixed to the top of the support column 1. An adaptive pressing mechanism 7 is installed inside the transmission box 5. The power input end of the adaptive pressing mechanism 7 is connected to the binding connection mechanism 6, and the power output end of the adaptive pressing mechanism 7 is connected to the bonding mechanism 4, so as to convert the swaying displacement of the seedling stem into the downward pressure of the bonding mechanism 4.

[0022] After the date palm seedlings are planted, the support 1 is first placed vertically at the preset points around the planting hole. The positioning mechanism 3 is inserted into the soil to complete the overall positioning and anchoring of the support 1, ensuring the stability of the installation benchmark. Then, the binding and connecting mechanism 6 is adjusted to fit against the stem of the date palm seedling, and the stem is flexibly wrapped and fixed by the binding and connecting mechanism 6 to support and limit the stem above ground, preventing the stem from tilting significantly due to external forces. At the same time, the fitting mechanism 4 is adjusted to unfold and press against the soil surface around the seedling roots to complete the pre-compacting and anchoring of the soil around the roots.

[0023] Under severe weather conditions such as strong winds and heavy rainfall, when the seedling stems sway and shift due to wind resistance and rain impact, the binding and connecting mechanism 6 will simultaneously shift horizontally. The binding and connecting mechanism 6 transmits the displacement power to the power input end of the adaptive downward pressing mechanism 7. Through the force transmission and reversal of the adaptive downward pressing mechanism 7, the horizontal swaying displacement of the stem is converted into a vertical downward pressure, which is then transmitted to the bonding mechanism 4 through the power output end. The greater the impact of the external force on the stem and the more obvious the swaying amplitude, the stronger the downward pressure output by the adaptive downward pressing mechanism 7 to the bonding mechanism 4. The bonding mechanism 4 has a more significant effect on the pressure and anchoring of the soil around the roots, forming a dynamic adaptive closed-loop protection. This not only dissipates the external impact load through the flexible swaying of the stem, but also simultaneously strengthens the holding capacity of the soil around the roots. This avoids the defects of the existing support structure's lever force transmission that leads to root and soil loosening, achieving dual anti-lodging protection under severe weather conditions.

[0024] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details: In this embodiment, the insertion positioning mechanism 3 includes a first screw 301, an anti-detachment block 302, a cone block 303, and a mounting plate 304. The first screw 301 is threaded into the bottom of the mounting groove 2. The cone block 303 is fixed to the bottom end of the first screw 301. The anti-detachment block 302 is fixedly installed on the top of the first screw 301. The mounting plate 304 is fixed to the bottom of the support column 1 to increase the contact area with the soil and improve the anchoring stability of the support column 1.

[0025] During the positioning and installation of the device, the rotating anti-detachment block 302 drives the first screw 301 to rotate at the bottom of the installation groove 2. According to the size of the plant, the length of the first screw 301 extending out of the installation groove 2 is controlled, thereby adjusting its soil penetration depth. Then, the cone block 303 is driven downward into the soil to complete the initial positioning of the support column 1. After the installation is completed, the bottom plate 304 of the support column 1 is completely attached to the ground surface, which greatly increases the contact area between the support column 1 and the soil, prevents the support column 1 from tilting due to lateral forces, and further improves the anchoring stability of the support column 1.

[0026] In this embodiment, the bonding mechanism 4 includes a crossbar 401, a nut 402, a second screw 403, a mounting block 404, a first pressure rod 405, and a second pressure rod 406. One end of the crossbar 401 is slidably disposed inside the mounting groove 2. The end of the crossbar 401 located inside the mounting groove 2 is connected to the power output end of the adaptive pressing mechanism 7. The end of the crossbar 401 away from the mounting groove 2 is fixed with a nut 402, and the second screw 403 is threadedly connected to the inside of the nut 402. Mounting block 404 is rotatably mounted on the bottom end of second screw 403. First pressure rods 405 are hinged to both sides of mounting block 404. Second pressure rods 406 are hinged to the ends of the first pressure rods 405 away from mounting block 404. The ends of the two sets of second pressure rods 406 are hinged to each other.

[0027] During installation, first adjust the expansion range of the first pressure rod 405 and the second pressure rod 406 according to the size of the planting hole and the distribution range of the seedling roots: pull the hinged ends of the two sets of second pressure rods 406, and drive the first pressure rod 405 to rotate around the mounting block 404 through the hinge transmission, thereby adjusting the overall expansion range of the pressure rods, and thus adjusting the contact pressing area between the pressure rods and the ground to adapt to the compaction requirements of planting holes of different sizes; after the expansion range is adjusted, rotate the second screw 403, and drive the second screw 403 to move vertically downward through the thread transmission between the second screw 403 and the nut 402, synchronously The installation block 404 is pushed downwards, so that the first pressure rod 405 and the second pressure rod 406 are completely pressed against the soil surface around the roots, completing the pre-compaction of the soil around the roots, preventing soil loss and root exposure caused by rainwater erosion, and improving the soil's wrapping and anchoring effect on the roots. During use, the downward pressure output by the adaptive pressing mechanism 7 can drive the horizontal bar 401 to slide vertically downwards along the installation groove 2, and simultaneously drive the installation block 404 to move further downwards through the nut 402 and the second screw 403, increasing the holding force of the first pressure rod 405 and the second pressure rod 406 on the soil, and achieving the effect of dynamic compaction and anchoring.

[0028] In this embodiment, a lever 407 is horizontally slidably disposed at the top end of the second screw 403, and spherical blocks are fixed at both ends of the lever 407.

[0029] When adjusting the pressure by rotating the second screw 403, the lever 407 can be pulled horizontally from the top of the second screw 403. By extending the rotation lever 407, the force required to rotate the second screw 403 is greatly reduced, making it easier for operators to quickly complete the screw adjustment. Precise control of the pre-pressure pressure can be achieved without the need for additional tools.

[0030] In this embodiment, the binding connection mechanism 6 includes a hinge seat 601, a sleeve 602, a slide rod 603, a first positioning bolt 604, a slip ring 605, a second positioning bolt 606, and a binding strap 607. The hinge seat 601 is connected to the power input end of the adaptive pressing mechanism 7. One end of the sleeve 602 is fixedly connected to the hinge seat 601. The slide rod 603 is slidably inserted into the inside of the sleeve 602. The first positioning bolt 604 is threadedly connected to the outer wall of the sleeve 602 to lock the extension and retraction position of the slide rod 603. The slip ring 605 is slidably sleeved on the outer wall of the slide rod 603. The second positioning bolt 606 is threadedly connected to the outer wall of the slip ring 605 to lock the sliding position of the slip ring 605. The binding strap 607 is installed on both sides of the slip ring 605 to bind and fix the stem of the date palm seedling.

[0031] When fixing the seedling stem, first rotate the sleeve 602 via the hinge seat 601 to adjust the support angle between the sleeve 602 and the slide rod 603, adapting to the support needs of seedlings of different heights; then pull the slide rod 603 to slide along the inside of the sleeve 602, adjusting the extension length of the slide rod 603 so that the end of the slide rod 603 fits against the outer wall of the seedling stem. After adjustment, tighten the first positioning bolt 604 to lock the extension position of the slide rod 603, completing the fixing of the support length; then push the sliding ring 605 to slide axially along the outer wall of the slide rod 603, adjusting the fixing position of the binding strap 607 to adapt to different heights. After adjusting the stem height to meet the binding requirements, tighten the second positioning bolt 606 to lock the sliding position of the slip ring 605. Finally, wrap the binding straps 607 on both sides of the slip ring 605 around the outside of the seedling stem to complete the flexible binding and fixing of the stem. This not only forms a reliable limiting constraint on the stem to prevent the stem from shaking significantly due to external forces, but also adapts to the slight shaking of the stem through the rotation of the hinge seat 601 and the extension and retraction of the slide rod 603, avoiding mechanical damage to the stem caused by rigid fixing. At the same time, the shaking displacement of the stem can be synchronously transmitted to the adaptive pressing mechanism 7 to provide power input for dynamic adaptive protection.

[0032] In this embodiment, limiting rings 609 are symmetrically fixed on both sides of the end of the slide rod 603 away from the sleeve 602. The binding strap 607 slides through the inside of the limiting ring 609. When binding the stem, the binding strap 607 passes through the limiting ring 609 and surrounds the stem. The limiting ring 609 can limit and constrain the position of the binding strap 607 to prevent the binding strap 607 from shifting or twisting during the binding process, ensuring that the binding strap 607 is evenly wrapped around the outside of the stem and improving the stability of the binding. A third positioning bolt 608 is connected between the end of the binding strap 607 and the outside of the slide ring 605 for locking and fixing the end of the binding strap 607.

[0033] After the binding strap 607 is wrapped around the stem, its end is fixed to the outside of the slip ring 605 by the third positioning bolt 608. This ensures the reliability of the binding limit and avoids the binding strap 607 being too tight and compressing the stem, which would affect the normal growth of the seedling. At the same time, it can adapt to the thickening needs of the stem during the growth process and does not require frequent replacement of the fixing structure.

[0034] In this embodiment, an arc-shaped groove is provided at the end of the slide rod 603 away from the sleeve 602, and a rubber anti-slip pad is provided inside the arc-shaped groove.

[0035] The arc-shaped groove at the end of the slide rod 603 can fit against the outer wall of the cylindrical seedling stem, increasing the contact area between the slide rod 603 and the stem, improving the stability of the support, and avoiding local pressure damage to the stem epidermis caused by point contact. The rubber anti-slip pad inside the arc-shaped groove can increase the friction between the slide rod 603 and the stem, preventing relative sliding between the stem and the slide rod 603 during swaying, ensuring that the swaying displacement of the stem can be completely and accurately transmitted to the binding connection mechanism 6 and the adaptive pressing mechanism 7, ensuring the response sensitivity of the dynamic adaptive protection. At the same time, the rubber anti-slip pad can further buffer the squeezing force between the stem and the slide rod 603, preventing wear on the stem epidermis and protecting the normal growth of the seedling.

[0036] In this embodiment, the adaptive pressing mechanism 7 includes an upper transmission rod 701, a fixing block 702, a first return spring 703, a wedge-shaped pressing block 705, a support block 706, a V-groove 707, a second return spring 708, a lower transmission rod 709, and a limiting block 710. The upper transmission rod 701 is horizontally slidably installed inside the transmission box 5, and one end of the upper transmission rod 701 extends to the outside of the transmission box 5. The upper transmission rod 701 is connected to the binding connection mechanism 6 in a transmission connection. The fixing block 702 is fixed at the middle position of the top of the upper transmission rod 701. The first return spring 703 is located between the transmission box 5 and the side of the fixing block 702, and the two ends of the first return spring 703 abut against the fixing block 702 and the inner side wall of the transmission box 5, respectively. The wedge-shaped pressure block 705 is fixed to the bottom end of the upper transmission rod 701, the support block 706 is located below the wedge-shaped pressure block 705, the top surface of the support block 706 is provided with a V-shaped groove 707 that is adapted to the wedge-shaped pressure block 705, and the second return spring 708 is located between the bottom of the support block 706 and the inner bottom of the transmission box 5. The top end of the lower transmission rod 709 is fixedly connected to the support block 706, and the bottom end of the lower transmission rod 709 slides into the interior of the mounting groove 2. A limit block 710 is fixed on the outer side of the bottom end of the lower transmission rod 709. The top of the limit block 710 fits against the inner top of the mounting groove 2 to limit the upper limit stroke of the lower transmission rod 709. The bottom end of the lower transmission rod 709 is connected to the fitting mechanism 4.

[0037] Under normal conditions, the first return spring 703 pushes the fixing block 702 with elastic force, keeping the upper transmission rod 701 in its initial position and ensuring stable support of the stem by the binding connection mechanism 6; the second return spring 708 pushes the support block 706 upward with elastic force, so that the top surface of the support block 706 fits against the bottom surface of the wedge-shaped pressure block 705, while the limiting block 710 on the outside of the lower transmission rod 709 fits against the inner top of the mounting groove 2, limiting the upward stroke of the lower transmission rod 709 and ensuring that the bonding mechanism 4 maintains a stable pre-pressed holding state.

[0038] When the seedling stem sways under external force, it pushes the binding connection mechanism 6 to generate a horizontal displacement, which in turn drives the upper transmission rod 701 to slide horizontally along the inside of the transmission box 5. When the upper transmission rod 701 slides, it drives the fixed block 702 to compress the first return spring 703, and at the same time drives the wedge-shaped pressure block 705 to move horizontally. When the wedge-shaped pressure block 705 moves horizontally, it converts the horizontal displacement into a vertical downward pressure by cooperating with the inclined surface of the V-shaped groove 707, which pushes the support block 706 to compress the second return spring 708 and move downward. When the support block 706 moves downward, it drives the lower transmission rod 709 to slide downward simultaneously. The bottom end of the lower transmission rod 709 transmits the downward pressure to the crossbar 401 of the bonding mechanism 4, which drives the bonding mechanism 4 to further compact the soil around the roots. The greater the swaying amplitude of the stem, the greater the displacement of the upper transmission rod 701, the stronger the downward pressure of the wedge-shaped pressure block 705 on the support block 706, and the more significant the soil holding and anchoring effect of the bonding mechanism 4, thus achieving dynamic adaptive anti-lodging protection.

[0039] When the external force disappears and the stem returns to its original position, the first return spring 703 pushes the fixed block 702 and the upper transmission rod 701 to return to their original positions through elastic force, which in turn drives the wedge-shaped pressure block 705 back to its initial position. The second return spring 708 pushes the support block 706 and the lower transmission rod 709 to return to their original positions through elastic force. The downward pressure of the bonding mechanism 4 is synchronously restored to the pre-compacted state, completing one adaptive protection cycle.

[0040] In this embodiment, a guide rod 704 is horizontally fixed at the top inner side of the transmission box 5. The guide rod 704 passes through the first reset spring 703 and the fixing block 702, and the guide rod 704 is slidably connected to the fixing block 702.

[0041] When the upper transmission rod 701 slides horizontally, the fixed block 702 slides synchronously along the outer wall of the guide rod 704. The guide rod 704 can precisely limit the sliding trajectory of the fixed block 702 and the upper transmission rod 701, preventing the upper transmission rod 701 from shifting vertically or twisting radially during sliding, ensuring that the upper transmission rod 701 always slides smoothly in the horizontal direction, ensuring the precise fit between the wedge-shaped pressure block 705 and the V-shaped groove 707, and improving the stability and accuracy of force transmission. At the same time, the guide rod 704 can radially limit the first return spring 703, preventing the first return spring 703 from bending radially during compression and reset, ensuring the stable spring force output of the first return spring 703, and extending the service life of the spring.

[0042] In this embodiment, anti-slip strips are evenly arranged on the top of the transmission box 5 along its length direction, and the anti-slip strips are parallel to the width direction of the transmission box 5.

[0043] When inserting the device into the ground, the top of the transmission box 5 can be struck with a heavy object, or the insertion and positioning mechanism 3 can be pressed into the soil by stepping on it, which makes it easier to fix the device.

[0044] The solutions in Embodiment 1 and Embodiment 2 will be further described below with reference to their specific working methods. On-site installation and usage steps of the device: The first step is to evenly arrange 2-4 sets of devices around the planting hole after the date palm seedlings are planted. Place the support column 1 of each set of devices vertically at the preset point, rotate the anti-detachment block 302 to control the first screw 301 to extend out of the installation groove 2, adjust the insertion depth, and then insert the first screw 301 and the cone block 303 downward into the soil so that the mounting plate 304 is completely attached to the ground surface, thus completing the positioning and anchoring of the support column 1. The second step is to adjust the unfolding range of the first pressure rod 405 and the second pressure rod 406 to match the size of the planting hole. By rotating the second screw 403 through the lever 407, the first pressure rod 405 and the second pressure rod 406 are pressed onto the soil surface around the roots to complete the pre-compaction. The third step is to adjust the support angle of the sleeve 602 by adjusting the hinge seat 601, pull the slide rod 603 to adjust the extension length, so that the arc groove at the end of the slide rod 603 fits the seedling stem, and tighten the first positioning bolt 604 to lock the length. Fourth step, adjust and lock the position of slip ring 605, pass the binding strap 607 through the limiting ring 609 and wrap it around the stem, adjust the tightness and lock it by the third positioning bolt 608 to complete the flexible fixation of the stem; Fifth, in severe weather, the swaying of the stem causes the upper transmission rod 701 to slide. Through the cooperation of the wedge-shaped pressure block 705 and the support block 706, the horizontal displacement is converted into the downward pressure of the lower transmission rod 709, which drives the bonding mechanism 4 to further compact the soil and achieve dynamic adaptive lodging prevention.
