Description

Technical Field

[0001] This invention relates to the technical field of forestry seedling cultivation, and in particular to a tetrapod cutting device. Background Technology

[0002] Tetrapanax is an ancient, relict, endangered plant belonging to the Zygophyllaceae family. It is a monotypic genus and has extremely high value in plant taxonomy and paleobotanical research.

[0003] In traditional tetrapod propagation by cuttings, it's crucial to ensure the substrate is loose, well-aerated, and nutrient-rich. Next, use chopsticks to make holes in the substrate, typically 8-10 cm deep. The hole walls should be slightly loose; if they are too tight, poor contact between the substrate and seedlings will occur later, severely impacting survival rates. After making the holes, insert the treated seedlings with good growth potential into them, ensuring they are upright and inserted to the appropriate depth. Finally, press the substrate around the seedling with your fingers to ensure close contact, providing a stable and suitable growing environment.

[0004] However, in the actual practice of manual cutting propagation, the depth of seedling insertion is often concealed, making it difficult for outsiders to directly observe. If the cutting is inserted too deeply, the roots may suffer from oxygen deficiency and root suffocation, severely impacting normal root respiration and growth. If the cutting is inserted too shallowly, the seedlings are prone to lodging and failing to establish stable growth. Furthermore, current cutting methods are quite cumbersome, requiring multiple steps such as punching holes, inserting seedlings, and sealing the holes. This necessitates a significant investment of time and effort from operators when cultivating individual seedlings, as each seedling involves numerous steps. More critically, during the sealing process, if the substrate is compacted during the initial punching, the pressed substrate cannot ensure proper pressure on the bottom and adhere to the seedling roots during subsequent sealing. This results in insufficient compaction between the substrate and the seedling roots. In such cases, the seedling roots remain suspended, unable to fully contact the substrate, severely hindering subsequent rooting and growth, and reducing the propagation success rate. Summary of the Invention

[0005] This invention proposes a four-section wood cutting propagation device, which has the advantages of first planting seedlings at a fixed height / spacing and then covering the roots with soil, in order to solve the problems mentioned in the background art of multiple procedures and inability to guarantee the planting depth when planting single seedlings.

[0006] To achieve the above objectives, this application adopts the following technical solution: a four-ply wood cutting propagation device, comprising: a seedbed, on which a female plate and a male plate are movably mounted; a positioning seat is fixedly mounted on one side of the surface of the female plate, and a positioning groove is provided on the side of the positioning seat; a locking seat is fixedly mounted on one side of the surface of the male plate, and a clamping component is provided on the side of the male plate; after the sides of the male plate and the female plate are attached together, the clamping component clamps and limits the seedlings between the positioning seat and the locking seat; a breathable bottom plate, with a locking component at the bottom, so that the breathable bottom plate is locked to the bottom of the inner side of the seedbed; during cutting, the seedling is inserted between the positioning seat and the locking seat, and its root touches the breathable bottom plate, and its side is limited by the clamping component; after the seedling cutting is completed, the seedbed is turned over, the breathable bottom plate is removed, and the substrate is spread on the roots of the seedlings.

[0007] Furthermore, handles are symmetrically fixed to the sides of the seedbed.

[0008] Furthermore, the seedbed surface is threaded with locking bolts to limit the position of the placed mother and male boards.

[0009] Furthermore, the positioning groove is a "V" shaped groove.

[0010] Furthermore, the clamping assembly includes a cotton block fixed to the side of the male board.

[0011] Furthermore, the clamping assembly also includes: a locking tongue, which is movably mounted on the top inner side of the locking seat, and a torsion spring is fixedly mounted on the rotating shaft at the top of the locking tongue, with the torsion spring being fixedly connected to the locking seat.

[0012] Furthermore, a locking slide is movably installed on the side of the locking seat, and a counterweight plate is fixedly installed in the middle of the surface of the locking slide.

[0013] Furthermore, the end of the locking slide is provided with an angle.

[0014] Furthermore, a vent pipe is fixedly installed on the surface of the vent plate below one end of the locking slide, and a reset push rod is fixedly installed on one side of the locking slide above the locking tongue.

[0015] Furthermore, the vent pipe is a cylindrical tube with mesh openings on the side.

[0016] The beneficial effects of this invention are as follows: This invention provides a four-ply wood cutting propagation device, in which multiple female and male boards are sequentially installed on the top of a seedbed, with the female and male boards cooperating with each other; simultaneously, a breathable bottom plate is fixed at the bottom of the seedbed. During the four-ply wood cutting propagation process, the operator only needs to insert the seedling between the female and male boards. Because a gap is reserved between the female and male boards, the spacing between seedlings is ensured to be relatively consistent; when the seedling is inserted, the root rests against the breathable bottom plate, while the side of the seedling is clamped and fixed by the female and male boards, thus ensuring that the depth of each seedling remains highly consistent during the cutting process.

[0017] After the cuttings are planted, the next step is to cover the roots with soil. At this stage, the operator simply flips the seedbed so that the roots of the seedlings, which were originally at the bottom, are facing upwards. Next, the aeration base is removed, and the roots can then be directly covered with soil. During this process, the substrate is evenly spread over the roots, ensuring complete coverage. Unlike traditional methods, this method avoids gaps between the substrate and the roots caused by compaction through holes, thus achieving the goal of covering the roots with soil.

[0018] In summary, the tetrapod cutting propagation method described in this application, on the one hand, utilizes a pre-fixed height / spacing method, ensuring that each seedling is inserted at a relatively consistent height through the positioning of the mother and male boards; on the other hand, the subsequent covering with soil ensures close contact between the substrate and the seedlings, creating favorable conditions for nutrient and water absorption. Furthermore, using this method, operators can perform the cutting operation on all seedlings uniformly before covering them with soil, eliminating the need for individual cutting and compaction processes for each seedling, thus reducing the operator's workload.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figure 1 and Figure 2 As can be seen, the seedbed 1 is a rectangular prism with a central through-section, and handles 101 are symmetrically fixed to the sides of the seedbed 1. The handles 101 allow the seedbed 1 to be moved and subsequently turned over. The seedbed 1 also has mounting protrusions symmetrically fixed to the sides below the handles 101. After the saplings are inserted into the seedbed 1, the entire seedbed 1 can be placed on the cultivation rack using the mounting protrusions at the bottom of the seedbed 1.

[0023] A female plate 2 and a male plate 3 are movably installed on the surface of seedbed 1. Specifically, rectangular grooves are cut into the surface of seedbed 1. As the ends of the female plate 2 and male plate 3 move along these grooves, they are guided and positioned. The female plate 2 and male plate 3 form a set. Figure 1 As can be seen from the above, this application has four sets, and the actual number can be adjusted according to the needs of use. After all four sets of female plates 2 and male plates 3 are movably installed on the surface of the seedbed 1, locking bolts 13 are threadedly connected to the surface of the seedbed 1. The locking bolts 13 can limit the placement of the female plates 2 and male plates 3, ensuring that the sides of the female plates 2 and male plates 3 are relatively close together.

[0024] from Figure 5 As can be seen, multiple positioning seats 4 are fixedly installed at equal intervals on one side of the surface of the mother plate 2. The positioning seats 4 are semi-cylindrical in shape, and positioning grooves 401 are opened on the side of the positioning seats 4. The positioning grooves 401 are "V" shaped grooves, which facilitate the positioning of the *Tetracentron sinense* seedlings. Figure 4As can be seen, multiple locking seats 5 are fixedly installed at equal intervals on one side of the male plate 3, and the locking seats 5 are also semi-cylindrical in shape. The radius of the locking seats 5 is the same as the radius of the positioning seat 4. Therefore, when the sides of the male plate 3 and the female plate 2 are attached together, the positioning seat 4 and the locking seats 5 form a cylinder with a through-center. It should be noted that both the female plate 2 and the male plate 3 are porous boards to facilitate substrate aeration and subsequent irrigation during the subsequent cultivation of tetrapods.

[0025] A clamping assembly is provided on the side of the male plate 3. In this embodiment, the clamping assembly is mainly fixed to the cotton block 8 on the side of the male plate 3, and the cotton block 8 is located below the locking seat 5. Figure 4 As can be seen, the locking seat 5 has an arc-shaped groove on its side, and the cotton block 8 is located at the bottom of the arc-shaped groove. In this way, when the male plate 3 and the female plate 2 are relatively close to each other and form a group, the seedling can be inserted between the positioning seat 4 and the locking seat 5. During the insertion process, the seedling is restricted by the cotton block 8, which forces the seedling to be arranged in a vertical clamping state after insertion.

[0026] A breathable bottom plate 7 is movably installed on the inner bottom of seedbed 1, located below the mother plate 2 and male plate 3. Each of the four corners of the bottom of the breathable bottom plate 7 is equipped with a locking component 701, primarily composed of bolts. To secure the breathable bottom plate 7, it is placed at the bottom of seedbed 1, and the bolts are threaded onto the bottom of the breathable bottom plate 7. By tightening the bolts, the ends of the bolts abut against the inner bottom of seedbed 1, thus securing the breathable bottom plate 7 firmly to the inner bottom of seedbed 1. During actual installation, adjusting the height of the breathable bottom plate 7 at the inner bottom of seedbed 1 adjusts the distance between the breathable bottom plate 7 and the mother plate 2 / male plate 3, i.e., the insertion depth of the seedlings.

[0027] The actual seedling cutting propagation process in this embodiment is as follows: First, install the female board 2 and male board 3 sequentially on top of the seedbed 1, and finally tighten the locking bolts 13 to ensure that the sides of the female board 2 and male board 3 are always in close contact. Install the breathable bottom plate 7 at the bottom of the seedbed 1, and adjust the spacing between the breathable bottom plate 7 and the female board 2 / male board 3 to adjust the actual cutting depth of the seedlings. Figure 6 The state shown is represented by the cylindrical rod, which symbolizes a seedling.

[0028] After pruning and chemical treatment, the seedlings are inserted between the positioning seat 4 and the locking seat 5. During insertion, the seedlings simultaneously pass through the cotton block 8. The deformation of the cotton block 8 under pressure clamps the seedlings, keeping them upright. Because adjacent positioning seats 4 / locking seats 5 are equidistantly arranged, the seedlings inserted between the positioning seats 4 and locking seats 5 are also equidistantly distributed. As more seedlings are inserted, their bottom ends eventually reach the surface of the ventilated bottom plate 7. At this point, the insertion depth of the seedling is equal to the distance between the ventilated bottom plate 7 and the female plate 2 / male plate 3. As more seedlings are sequentially inserted between the positioning seats 4 and locking seats 5, it ensures that the insertion depth of each seedling is relatively consistent.

[0029] After the seedlings have been planted in seedbed 1, the operator rotates seedbed 1 180° using handle 101. Then, the locking assembly 701 is removed and the breathable bottom plate 7 is taken out. Since seedbed 1 is now positioned with its bottom facing upwards, the seedlings are held in place by the cotton blocks 8, ensuring their roots are facing upwards. The operator then lays substrate at the bottom of the inner cavity of seedbed 1, ensuring that the substrate covers the roots of each group of seedlings.

[0030] Finally, the breathable bottom plate 7 is reinstalled at the bottom of the inner cavity of the seedbed 1. Then, the seedbed 1 is rotated 180° again and placed on the cultivation rack. The seedlings after the cuttings are planted will be treated later.

[0031] After the seedlings have been cultivated, remove the locking bolt 13 and then take out the male plate 3, female plate 2, and seedlings in sequence. In this way, the disassembled female plate 2 and male plate 3 can still be used, allowing the cutting device to be reused.

[0032] It should be noted that in this application, the turning operation is only performed during the soil covering stage, and its duration is short, not a long-term inverted growth. Furthermore, the polar transport and geotropic response of auxin are continuous and cumulative physiological processes; short-term, reversible directional turning is insufficient to cause heritable or cumulative hormonal disorders. In Tetrapanax papyrifer cuttings, the key stress affecting difficult-to-root species of Tetrapanax papyrifer is not short-term directional change, but rather cut damage, water loss, infection, and environmental fluctuations. Short-term mechanical turning does not increase cut damage, change temperature and humidity, or exacerbate oxidative browning; therefore, it does not constitute additional substantial physiological stress.

[0033] Example 2 is a further improvement on Example 1. Please refer to Example 1. Figures 6-8 As shown, the clamping assembly may further include a locking tongue 9, one end of which is movably mounted on the top inner side of the locking seat 5. A torsion spring 901 is fixedly mounted on the pivot at the top of the locking tongue 9, and the torsion spring 901 is fixedly connected to the locking seat 5. Under normal conditions, the locking tongue 9 tends to deflect away from the locking seat 5 due to the elastic force of the torsion spring 901. Figure 6 and Figure 7As shown, when the seedling is inserted between the positioning seat 4 and the locking seat 5, the seedling will first cause the locking tongue 9 to rotate clockwise along the top pivot. As the seedling is continuously inserted, the locking tongue 9, under the elastic force of the torsion spring 901, will always press against the side of the seedling. This ensures that after the seedling is inserted, the locking tongue 9 pushes the seedling against the positioning groove 401 of the positioning seat 4, thereby clamping and securing the seedling. This ensures that after the seedling is flipped over, it will be clamped by the locking tongue 9 and will not come off between the positioning seat 4 and the locking seat 5.

[0034] Furthermore, a locking slide 11 is movably mounted on the side of the locking seat 5, and the locking slide 11 can only move up and down along the axial direction of the side of the locking seat 5. The end of the locking slide 11 located in the inner cavity of the locking seat 5 is provided with an angle. A counterweight plate 12 is fixedly mounted on the middle of the surface of the locking slide 11. Under the influence of gravity, the counterweight plate 12 can drive the locking slide 11 to move up and down along the axial direction of the locking seat 5 before and after the locking seat 5 is rotated. Specifically, when the male plate 3 is on top and the seedling cutting work begins, the counterweight plate 12 is pressed against the locking slide 11 by gravity, so that the locking slide 11 is relatively away from the locking tongue 9. At this time, the locking tongue 9 is only subjected to the elastic force of the torsion spring 901 to complete the clamping of the seedling. Similarly, when the seedbed 1 is rotated 180°, the male plate 3 is below the seedbed 1. At this time, the counterweight plate 12 is pulled by gravity to the side of the locking tongue 9. During this process, the locking slide 11 presses down on the locking tongue 9, forcing it to increase its clamping strength on the seedlings, further enhancing the clamping force on the seedlings and preventing the seedlings from detaching from the positioning seat 4 and the locking seat 5 after being inverted. Secondly, the locking slide 11 abuts against the locking tongue 9, restricting the locking tongue 9 from deflecting towards the locking seat 5, thus ensuring that the locking tongue 9 can only deflect outwards and stably clamp the seedlings at this time.

[0035] Based on this, from Figure 3 , Figures 6-8 As can be seen, a ventilation pipe 6 is fixedly installed on the surface of the ventilation base plate 7, located below one end of the locking slide 11. The number of ventilation pipes 6 corresponds to the number of locking slides 11. The ventilation pipe 6 is a cylindrical tube with mesh openings on the side. During the seedling cutting propagation process, the ventilation pipe 6 extends from the male plate 3 and abuts against the locking slide 11. Correspondingly, a reset push rod 10 is fixedly installed on one side of the surface of the locking slide 11, located above the locking tongue 9. The reset push rod 10 is n-shaped and extends from... Figure 7It is clearly visible that one end of the reset push rod 10 is fixedly connected to one side of the surface of the locking slide 11, ensuring that the reset push rod 10 can move up and down with the locking slide 11. The other end of the reset push rod 10 is located above the locking tongue 9. When the locking slide 11 pushes the reset push rod 10 up / down, the reset push rod 10 can move relatively away from / close to the locking tongue 9. More specifically, when the vent pipe 6 pushes the locking slide 11 upward, the reset push rod 10 moves relatively away from the locking tongue 9. At this time, the reset push rod 10 does not restrict the movement of the locking tongue 9. When the seedling is inserted between the positioning seat 4 and the locking seat 5, the locking tongue 9, which is subjected to the elastic force of the torsion spring 901, will press down on the seedling, achieving pressure and clamping of the seedling. Similarly, when the vent pipe 6 no longer supports the locking slide 11, such as Figure 7 As shown, the locking slide 11 is pressed down by the gravity of the counterweight plate 12, which pulls the reset push rod 10 downward. During the downward movement of the reset push rod 10, its end will abut against the right side of the locking tongue 9, forcing the locking tongue 9 to have a clockwise rotation tendency. As the reset push rod 10 continues to move downward, the reset push rod 10 eventually causes the locking tongue 9 to retract to the inside of the locking seat 5, and the locking tongue 9 will eventually move away from the seedling.

[0036] In practical application, the specific details of this second embodiment are as follows: Before transplanting the seedlings, the ventilated base plate 7 is first fixed in place. At this time, the ventilated pipe 6 needs to extend from the male plate 3 and push the locking slide 11 upward. At this time, the locking slide 11 is not in contact with the locking tongue 9, and the reset push rod 10 is also relatively far away from the locking tongue 9. Since the locking slide 11 leaves a certain distance from the upper locking tongue 9, the ventilated base plate 7 can move up and down within a certain range to adjust the actual depth of seedling transplanting.

[0037] Afterwards, when the treated seedlings are inserted between the positioning seat 4 and the locking seat 5, the roots of the seedlings press against the breathable bottom plate 7, while the sides are held in place by the locking tongue 9. At this time, the pressing strength of the locking tongue 9 comes from the elastic force of the torsion spring 901.

[0038] After the seedlings are planted, the seedbed 1 is rotated 180°. Under the action of gravity, the counterweight plate 12 pulls the locking slide 11, causing it to press against the locking tongue 9. This strengthens the pressure of the locking tongue 9 on the seedlings and restricts the deflection of the locking tongue 9 towards the locking seat 5, ensuring that the seedlings will not fall off between the positioning seat 4 and the locking seat 5 during the soil covering process. At the same time, when the ventilated bottom plate 7 is disassembled, the ventilated pipe 6 is also disassembled simultaneously. Subsequently, the substrate spreading work is carried out according to the description in Example 1.

[0039] Since the seedling roots need to be completely buried after the substrate is spread, a gap is left between the breathable base plate 7 and the seedling roots due to the presence of the substrate after the breathable base plate 7 is reinstalled. This gap ensures that the top of the breathable pipe 6 is lower than the surface of the male plate 3. Furthermore, when the breathable pipe 6 is inserted into the substrate, it enables ventilation and drainage between the substrate and the outside. After the seedbed 1 is covered with soil and rotated 180° again, the counterweight plate 12 is pressed down by gravity, causing the locking slide 11 to move downwards. At this time, the lower part of the locking slide 11 is no longer obstructed by the breathable pipe 6, so the locking slide 11 will descend to the bottom, driving the reset push rod 10 to descend simultaneously. During the descent of the reset push rod 10, it will reach the locking tongue 9 and deflect towards the locking seat 5, releasing it from clamping the seedlings. Ultimately, this ensures that the seedlings are no longer excessively clamped after planting and covering with soil, thus avoiding problems caused by clamping that interfere with seedling growth.
