Description

Technical Field

[0001] The invention relates to the technical field of seedling extractors, and in particular to a seedling extractor used for vegetation reconstruction. Background Art

[0002] Vegetation reconstruction is an ecological restoration measure. It mainly aims to re-establish vegetation communities through human intervention in areas where vegetation has been destroyed or where vegetation coverage is insufficient. During the vegetation reconstruction process, vegetation seedlings are transplanted and planted by artificial transplanting. Usually, transplanting and planting are assisted by special seedling removers to improve planting efficiency.

[0003] When using the existing seedling remover, the operator is mostly required to hold it with both hands to remove and put in the seedlings. In actual use, since the bottom of the seedling remover is not provided with a specific fixed structure according to the soil conditions, when the soil is relatively loose, the seedlings are easily scattered during removal due to the looseness of the soil, exposing the root system of the seedlings. As a result, when the seedlings are placed in the transplanting pit, there is not enough soil to protect the seedlings, so that the transplanting and planting risks of the seedlings are high and the survival rate of the seedlings is reduced. In this case, new soil needs to be taken for supplementation to complete the seedling planting and transplanting operations, which makes the seedling transplanting efficiency slow during vegetation reconstruction. Summary of the invention

[0004] In order to reduce the problem of reduced survival rate of seedlings due to soil scattering caused by a seedling remover during seedling transplanting operations, the present invention adopts the following technical solutions:

[0005] A seedling extractor for vegetation reconstruction, comprising a seedling extractor tube and a support frame, wherein the support frame is fixed to the top of the seedling extractor tube, a blade ring is threadedly sleeved on the bottom end of the seedling extractor tube, installation windows are provided on both left and right sides of the seedling extractor tube, a seedling stem notch is provided on the front of the seedling extractor tube, a soil clamping plate is provided on the inner side of the installation window, a locking frame is provided on the outer side of the soil clamping plate, a fixed shaft is rotatably provided on the top of the soil clamping plate, two ends of the fixed shaft are respectively connected to the inner top of the installation window, and a torsion spring A located inside the soil clamping plate is provided on the fixed shaft;

[0006] The seedling taking tube is provided with a guide convex strip, the seedling taking tube is movably provided with a positioning ring, the seedling taking tube is movably provided with a seedling withdrawing ring, and connecting rods are provided on both sides of the left and right sides of the seedling withdrawing ring.

[0007] Preferably, a first guide groove which is slidably fitted with the guide ridge is provided on the outer side of the positioning ring, and a second guide groove which is slidably fitted with the guide ridge is provided on the outer side of the seedling withdrawal ring.

[0008] Preferably, a locking rod is provided on the positioning ring, a rod-penetrating hole is provided on the top of the seedling-taking tube for the locking rod to pass through and enter the locking frame, and a balancing hole is provided on the positioning ring to be movably fitted with the connecting rod.

[0009] Preferably, a limiting hole is opened on the side of the support frame, a handle is provided on the inner side of the support frame, a mounting plate is provided on the top of the connecting rod, a limiting groove that is movably fitted with the limiting hole is provided at the end of the mounting plate, and a straight rack located on the outside of the support frame is provided at the end of the mounting plate.

[0010] Preferably, an extension plate is provided at the end of the handle, and a rotating shaft is provided on the inner side of the support frame.

[0011] Preferably, a synchronous gear meshing with the spur rack is provided at one end of the rotating shaft, and a power storage mechanism is provided at the other end of the rotating shaft.

[0012] Preferably, the force storage mechanism comprises a ratchet disc connected to a rotating shaft, an assembling frame is provided on the extension plate, and a pressure rod is rotatably provided on the assembling frame.

[0013] Preferably, the assembly frame is provided with a torsion spring B connected to a pressure rod, and the end of the pressure rod is provided with a ratchet rod which is unidirectionally engaged with the ratchet disc.

[0014] Preferably, a locking assembly is rotatably mounted on the ratchet disc, and the locking assembly includes a fixed disc fixedly mounted on the inner side of the support frame, and a cover plate rotatably sleeved with the axis of the ratchet disc is provided on the other side of the fixed disc, and a mainspring with one outer end connected to it is provided inside the fixed disc, and an inner end of the mainspring is fixedly connected to the end of the ratchet disc.

[0015] Preferably, a seedling protection tube is provided on the inner side of the seedling withdrawal ring, a reset spring is provided on the positioning ring, and a baffle for connecting the top of the reset spring is provided on the top of the guide convex strip.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By installing a soil clamping plate inside the window, during the seedling removal process, the soil clamping plate can clamp the soil carried by the seedlings taken out of the seedling tube at the bottom, and a fixed shaft is provided at the top for rotation. The fixed shaft is provided with a torsion spring A located inside the soil clamping plate. After the locking frame releases the lock on the soil clamping plate, the elastic potential energy of the torsion spring A can drive the soil clamping plate to rotate around the fixed shaft. This design can effectively prevent the soil from scattering due to loose soil, ensure the soil integrity at the root of the seedling, and is conducive to the survival of the seedlings after transplanting.

[0018] 2. A guide convex strip is provided in the seedling taking tube, a first guide groove is provided on the outer side of the positioning ring and is slidably fitted with the guide convex strip, and a second guide groove is provided on the outer side of the seedling withdrawing ring and is slidably fitted with the guide convex strip. The setting of the guide convex strip allows the positioning ring and the seedling withdrawing ring to move straight up and down inside the seedling taking tube, and the provision of the first guide groove and the second guide groove allows the guide convex strip to provide a stable guide for the positioning ring and the seedling withdrawing ring when they are adjusted in height inside the seedling taking tube, thereby ensuring the stability and accuracy of the movement of each component during the seedling taking and withdrawing process, and reducing the damage to the seedlings caused by factors such as component shaking.

[0019] 3. Connecting rods are provided on both sides of the seedling withdrawing ring, and a seedling protection tube is provided on the inner side of the seedling withdrawing ring. During the process of taking and withdrawing seedlings, the seedling protection tube can protect the roots and stems of the seedlings, reduce the damage to the roots and stems of the seedlings during the operation, and improve the survival rate of the seedlings after transplanting.

[0020] 4. By setting up the power storage mechanism, the power of the winding spring is utilized to store power, so that when the seedling taking tube is taking seedlings, the spring can store power. When the seedling taking tube needs to withdraw the seedlings, the early power storage of the spring can drive the seedling withdrawing ring to press down the seedlings and the accompanying soil, thereby improving the efficiency of seedling taking and planting, and no additional power source is required.

[0021] In summary, the present invention overcomes the shortcomings of the prior art. When performing seedling removal operations, the bottom and sides of the soil can be clamped according to the looseness of the soil, thereby preventing the loose soil from falling and affecting subsequent planting operations and the normal growth of subsequent seedlings. The present invention has high social use value and application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

A locking frame 21 is provided on the outer side of the soil clamping plate 2, and a fixed shaft 201 is provided at the top of the soil clamping plate 2 for rotation. The two ends of the fixed shaft 201 are respectively connected to the top of the inner side of the installation window 102, and a torsion spring A202 located inside the soil clamping plate 2 is provided on the fixed shaft 201. After the locking frame 21 releases the lock of the soil clamping plate 2, the elastic potential energy of the torsion spring A202 can drive the soil clamping plate 2 to rotate around the fixed shaft 201, so that the soil clamping plate 2 can be adjusted by 5 degrees around the fixed shaft 201. During actual use, the clamping force and angle of the soil clamping plate 2 can be replaced and adjusted according to the actual elastic potential energy of the torsion spring A202;

[0035] A guide convex strip 105 is provided in the seedling taking tube 1, a positioning ring 3 is movably provided in the seedling taking tube 1, a seedling withdrawing ring 4 is movably provided in the seedling taking tube 1, and connecting rods 42 are provided on the left and right sides of the seedling withdrawing ring 4. Through the setting of the guide convex strip 105, the positioning ring 3 and the seedling withdrawing ring 4 can move straight up and down inside the seedling taking tube 1.

[0036] Specifically, refer to Figure 1-6 A first guide groove 301 is provided on the outer side of the positioning ring 3 and is slidably fitted with the guide ridge 105. A second guide groove 401 is provided on the outer side of the seedling withdrawing ring 4 and is slidably fitted with the guide ridge 105. The provision of the first guide groove 301 and the second guide groove 401 enables the guide ridge 105 to provide stable guidance for the positioning ring 3 and the seedling withdrawing ring 4 when the height is adjusted inside the seedling taking tube 1.

[0037] Specifically, refer to Figure 1 and Figure 4-6When the locking rod 31 is in the locked state, the locking rod 31 is in the locked state, and the locking rod 31 is in the locked state again, so that the locking rod 31 is locked in the locked state again.

During the downward movement of the seedling withdrawing ring 4, the soil clamping plate 2 will be squeezed, so that the soil clamping plate 2 is reset and embedded in the installation window 102.

[0039] Example 2

[0040] Reference Figure 1-8 The difference between this embodiment and embodiment 1 is that a limiting hole 501 is provided on the side of the support frame 5, a handle 51 is provided on the inner side of the support frame 5, a mounting plate 421 is provided on the top of the connecting rod 42, a limiting groove 422 which is movably fitted with the limiting hole 501 is provided at the end of the mounting plate 421, and a straight rack 7 located on the outer side of the support frame 5 is provided at the end of the mounting plate 421. Through the opening of the limiting hole 501, when the connecting rod 42 drives the mounting plate 421 to move upward, the guiding set between the limiting groove 422 and the limiting hole 501 is cooperated, so that the mounting plate 421 can smoothly drive the straight rack 7 to move upward.

[0041] Specifically, refer to Figure 1-3 and Figure 5An extension plate 511 is provided at the end of the handle 51 , a rotating shaft 6 is provided inside the support frame 5 , and the connection between the rotating shaft 6 and the support frame 5 is arranged in a rotating manner, so that the rotating shaft 6 can rotate relative to the support frame 5 .

[0042] Specifically, refer to Figure 2 A synchronous gear 61 meshing with the spur rack 7 is provided at one end of the rotating shaft 6, and a force storage mechanism 8 is provided at the other end of the rotating shaft 6. When the spur rack 7 moves upward, the spur rack 7 can mesh with the synchronous gear 61, so that the spur rack 7 can drive the synchronous gear 61 to rotate. When the synchronous gear 61 is driven by the rotating shaft 6 to rotate in the opposite direction, the synchronous gear 61 can mesh with the spur rack 7, so that the spur rack 7 moves downward, thereby driving the mounting plate 421 and the connecting rod 42 to move downward, so that the seedling withdrawing ring 4 pushes the seedlings and seedling soil inside the seedling taking tube 1 downward.

[0043] Specifically, refer to Figure 2 , Figure 3 and Figure 8 The force storage mechanism 8 includes a ratchet disc 801 connected to the rotating shaft 6, an assembly frame 802 is provided on the extension plate 511, and a pressure rod 803 is rotatably connected to the assembly frame 802. When the synchronous gear 61 drives the rotating shaft 6 to rotate, the rotating shaft 6 can drive the ratchet disc 801 to rotate.

[0044] Specifically, refer to Figure 2 , Figure 3 and Figure 8 A torsion spring B804 connected to the pressure rod 803 is provided on the assembly frame 802, and a pawl rod 8031 ​​unidirectionally engaged with the ratchet disc 801 is provided at the end of the pressure rod 803. When the ratchet disc 801 is driven by the rotating shaft 6 to rotate forward, the pawl rod 8031 ​​will not affect the rotation of the ratchet disc 801.

[0045] Specifically, refer to Figure 2 , Figure 3 and Figure 8The ratchet disc 801 is rotatably mounted with a locking assembly 805, which includes a fixed disc 8051 fixedly mounted on the inner side of the support frame 5, and a cover plate 8052 rotatably sleeved with the axis of the ratchet disc 801 is provided on the other side of the fixed disc 8051, and a spring 8053 is provided inside the fixed disc 8051 at one end of the outer side connected thereto, and an inner end of the spring 8053 is fixedly connected to the end of the ratchet disc 801. When the ratchet disc 801 rotates, the spring 8053 is wound inside the fixed disc 8051, so that the spring 8053 accumulates potential energy, and the rotation of the pawl rod 8031 ​​and the ratchet disc 801 When the pressure rod 803 is pressed to release the rotation restriction of the ratchet disc 801, the winding force of the mainspring 8053 will be released, so that the ratchet disc 801 can drive the rotating shaft 6 to reverse, thereby allowing the synchronous gear 61 to engage and match with the spur rack 7, so that the spur rack 7 can move downward, and the spur rack 7 can cooperate with the mounting plate 421 and the connecting rod 42 to drive the seedling withdrawal ring 4 to push the soil with the seedlings downward, so that the soil can be pushed into the predetermined pit to complete the reconstruction and planting of vegetation.

[0046] For other structures not described, refer to Example 1.

[0047] Working principle: In the present invention, the handle 51 can be held with one hand first, and then the seedling taking tube 1 is passed through the seedling stem notch 103 to allow the seedling to be inside the seedling taking tube 1, and then the blade ring 101 is inserted into the soil, and then the seedling taking tube 1 can be inserted into the soil;

[0048] When the seedling-taking tube 1 is inserted into the soil, the soil around the seedlings will push the seedling-removing ring 4 upward, allowing the seedling-removing ring 4 to move upward, so that the seedling-removing ring 4 releases the side limit of the soil clamping plate 2. When the seedling-removing ring 4 quickly moves to the top of the seedling-taking tube 1, the top surface of the seedling-removing ring 4 can contact the bottom surface of the positioning ring 3. As the seedling-removing ring 4 continues to move upward, the positioning ring 3 can be driven upward synchronously. At this time, the return spring 32 will be compressed. At the same time, the locking rod 31 will follow the positioning ring 3 to move upward, so that the bottom end of the locking rod 31 is pulled out from the inside of the locking frame 21. The soil clamping plate 2 will rotate under the action of the fixed shaft 201 and the torsion spring A202 to clamp the bottom of the soil side inside the seedling-taking tube 1;

[0049] When the seedling withdrawing ring 4 moves upward relative to the seedling taking tube 1, the connecting rod 42 and the mounting plate 421 drive the spur rack 7 to move upward, and the spur rack 7 engages with the synchronous gear 61, so that the rotating shaft 6 drives the ratchet disk 801 to rotate, so that the mainspring 8053 can be wound up and store force, and cooperates with the one-way rotation restriction between the pawl rod 8031 ​​and the ratchet disk 801, so that the mainspring 8053 is in a rotation restriction state;

[0050] After the seedlings and the soil attached thereto are completely inside the seedling taking tube 1, the handle 51 can be held to pull the seedling taking tube 1 upwards, so that the seedling taking tube 1 is withdrawn from the soil pit formed by the seedling taking;

[0051] The seedling-taking tube 1 loaded with the seedlings and the accompanying soil is aligned with the top of the soil pit where vegetation reconstruction is required, and then the thumb of the hand holding the handle 51 is used to press the pressure rod 803, so that the rotation restriction of the ratchet plate 801 by the pawl rod 8031 ​​is released, so that the winding and storage force of the mainspring 8053 will be released, and the ratchet plate 801 drives the rotating shaft 6 to rotate in the opposite direction, so that the synchronous gear 61 and the spur rack 7 are meshed and matched, so that the spur rack 7 moves downward, thereby driving the seedling-removing ring 4 to move downward, so as to allow the seedling-removing ring 4 to transport the seedlings and the accompanying soil loaded in the seedling-taking tube 1 into the soil pit for vegetation reconstruction, so that the seedlings can be pushed into the reserved soil pit, and with the downward pressure of the seedling-removing ring 4, the accompanying soil around the seedlings can be compacted downward;

[0052] After the contact between the seedling withdrawing ring 4 and the positioning ring 3 is separated, the elastic deformation of the reset spring 32 will be restored, so that the positioning ring 3 can move downward relative to the seedling removing tube 1, so that the locking rod 31 can cooperate with the elastic potential energy of the reset spring 32. After the soil clamping plate 2 is completely embedded in the installation window 102 by the downward movement of the seedling withdrawing ring 4, the locking rod 31 will be inserted into the locking frame 21, so that the locking rod 31 cooperates with the seedling withdrawing ring 4 to complete the position locking of the soil clamping plate 2.

[0053] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
