Description

Technical Field

[0001] This invention belongs to the field of bamboo seedling technology, and particularly relates to a bamboo seedling device. Background Technology

[0002] Bamboo, as a fast-growing, economically valuable, and ecologically significant grass, has a wide range of applications in building materials, papermaking, furniture, and ecological restoration. Current bamboo seedling cultivation techniques mostly employ open-field methods or facility cultivation.

[0003] Currently, traditional bamboo seedling cultivation devices mostly use top watering or sprinkler irrigation methods. This method easily leads to the soil or substrate inside the container being "wet on top and dry on the bottom," or some parts being too dry while others are too wet. This uneven moisture environment prevents bamboo seedlings from forming a well-developed and uniform root network, which in turn affects their absorption of water and nutrients, resulting in slow growth, weak plants, and poor resistance to adverse conditions. Secondly, existing seedling cultivation devices generally lack targeted protection for the bamboo leaves of bamboo seedlings. During handling, loading, unloading, and transplanting operations, the branches of the seedlings are easily broken due to collisions, squeezing, or improper handling. This damage not only directly affects the ornamental value of the bamboo seedlings but also destroys their apical dominance, seriously delaying their recovery and growth, and even leading to transplanting failure. Summary of the Invention

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This invention provides a bamboo seedling raising device, such as... Figure 1-13 As shown, the bamboo seedling raising device includes: a base 1 and a seedling bed 2 fixedly installed on the base 1; a seedling tray 3 for bamboo seedling raising disposed in the seedling bed 2; a fixing frame 4 fixedly installed on the base 1, with a connecting plate 5 fixedly installed on one side of the fixing frame 4; a drainage pipe 6 installed on the connecting plate 5 for irrigating the top of the bamboo; an irrigation pipe 7 installed on one side of the seedling bed 2 for irrigating the bottom of the bamboo; a net cover 9 for protecting the bamboo leaves on the seedling tubes fitted onto the seedling tray 3; and a moving mechanism disposed on the fixing frame 4 for fitting the net cover 9 onto the bamboo leaves.

[0022] In this embodiment, before planting ornamental bamboo seeds, soil or substrate is filled into each seedling tube of the seedling tray 3, and then the seeds (or bamboo plants or bamboo rhizomes) are sown. During the seedling process, surface irrigation is carried out through the top drainage pipe 6, and water or nutrient solution is injected into the seedling bed 2 through the irrigation pipe 7 on one side of the seedling bed 2. The liquid level rises and the seeds are bottom-irrigated through the ventilation holes at the bottom of the seedling tray 3 to ensure a uniform supply of water. After irrigation, the water or nutrient solution in the seedling bed 2 is drained through the connecting pipe on one side of the seedling bed 2 to avoid the seedling roots from being soaked in water for a long time. After the seedlings are cultivated, before transplanting or transporting them, the moving mechanism is activated to drive the ring plate 10 to rise. The spikes 11 on the ring plate 10 lift the protective netting 9 that was originally covering the outside of the seedling tube upwards, so that it changes from covering the seedling tube to covering the branches and leaves of the bamboo seedlings, forming effective protection and preventing the branches and leaves from breaking due to collision or squeezing during subsequent operations. This is crucial for maintaining the shape and value of ornamental bamboo. After transplanting and fixing the seedlings, the netting 9 can be removed, and then a new netting 9 can be put back on the seedling tube to prepare for the next round of seedling cultivation. By combining top watering and bottom irrigation, the soil or substrate in the seedling tube is kept evenly moist, avoiding the phenomenon of "wet on top and dry on the bottom" or uneven moisture distribution. This promotes the formation of a well-developed and healthy root network in the bamboo seedlings, enhancing their ability to absorb water and nutrients. Through a liftable moving mechanism and netting system, the netting 9 can be automatically lifted from the seedling tube to cover the entire branch and leaves before transplanting. This effectively avoids collisions, compression, and breakage of the seedling branches and leaves during handling, loading, unloading, and transplanting, especially protecting the morphological value and apical growth advantage of the ornamental bamboo.

[0023] In a further preferred embodiment of the present invention, a ventilation opening for ventilation of the bottom of the seedling tray 3 is provided on one side of the seedling bed 2, and a sealing plate 8 for sealing the ventilation opening is hinged inside the ventilation opening, and a connecting groove is provided on one side of the seedling tube.

[0024] In this embodiment, after bottom irrigation is completed, in order to control the microenvironment inside the seedling bed 2, the sealing plate 8 hinged to the vent can be opened to allow air circulation, effectively reducing the temperature and humidity inside the bed and preventing high temperature and humidity from adversely affecting the seedlings. The connecting groove opened on one side of the seedling tube mainly provides a path for the piercing and fixing of the sharp needles 11 when using the net sleeve 9, ensuring that the net sleeve 9 can be stably fixed in the initial state (on the tube) and the lifted state (on the branches and leaves).

[0025] In a further preferred embodiment of the present invention, the moving mechanism includes: a one-way screw 12 rotatably mounted on the fixed frame 4; a first slider 13 threaded onto the one-way screw 12, with a support frame 14 mounted on the first slider 13; a fixed plate 15 fixedly mounted on the support frame 14, the bottom of the fixed plate 15 having an annular plate 10 adapted to the seedling tube; a spiked needle 11 located below the annular plate 10 for fixing the net sleeve 9, the spiked needle 11 being inclined and penetrating the net sleeve 9; a connecting rod 16 rotatably mounted on the top of the inner wall of the fixed frame 4; first bevel gears 17 respectively sleeved on the connecting rod 16 and the one-way screw 12, the two first bevel gears 17 meshing with each other; and a first motor 18 fixedly mounted on the top of the fixed frame 4, the output shaft of the coupling of the first motor 18 being fixedly connected to the one-way screw 12.

[0026] In this embodiment, when it is necessary to lift the netting 9 to protect the branches and leaves, the first motor 18 at the top of the fixing frame 4 is started. The output shaft of the first motor 18 drives the one-way screw 12 to rotate. Since the one-way screw 12 and the first slider 13 are threaded together, the first slider 13 moves upward along the screw. The first slider 13 drives the support frame 14 and the fixing plate 15 fixed thereon to rise synchronously. The fixing plate 15 drives the annular plate 10 to move upward together. The annular plate 10 drives the netting 9 to move upward from the outside of the seedling tube through the spikes 11 set on it. Finally, the netting 9 is completely covered on the outside of the branches and leaves of the bamboo seedling. Through the setting of the connecting rod 16 and the first bevel gear 17, a set of one-way screws 12 can rotate synchronously, so that the rotational motion is stably transmitted.

[0027] In a further preferred embodiment of the present invention, a fixing block 19 is fixedly installed at the bottom of the annular plate 10, and a first return spring 20 is fixedly installed on one side of the fixing block 19. The first return spring 20 is sleeved on the support rod of the spike needle 11, and one end of the first return spring 20 is fixedly connected to a baffle at one end of the support rod. A first take-up roller 21 is rotatably installed on one side of the annular plate 10. The first take-up roller 21 is equipped with a first pull rope 22 for pulling the spike needle 11 back. One end of the first pull rope 22 is fixedly connected to the support rod. The annular plate 10 and the fixing frame 4 are provided with a driving mechanism for driving the first take-up roller 21 to take up or release the first pull rope 22. A fixing cover 23 is fixedly installed on one side of the annular plate 10, and the fixing cover 23 is fixedly connected to the bracket of the fixing plate 15.

[0028] In this embodiment, a fixing block 19 is fixed at the bottom of the annular plate 10. The support rod of the spike 11 passes through the fixing block 19 and is fitted with a first return spring 20. One end of the spring abuts against the fixing block 19, and the other end is connected to the baffle at the end of the support rod, so that the spike 11 tends to extend outward in its natural state, thereby being able to pierce and fix the net sleeve 9. When it is necessary to separate the spike 11 from the net sleeve 9 (for example, after transplanting), the first winding roller 21 is driven by the driving mechanism to wind up the first pull rope 22. The first pull rope 22 pulls the support rod of the spike 11, causing it to overcome the elasticity of the first return spring 20 and retract inward, thereby detaching from the net sleeve 9, which facilitates the subsequent transplanting of bamboo seedlings.

[0029] In a further preferred embodiment of the present invention, the driving mechanism includes: a mounting groove formed in the annular plate 10; a first gear 24 rotatably mounted in the mounting groove, the shaft of the first gear 24 being fixedly connected to the shaft of the first winding roller 21; a guide block 26 fixedly mounted in the mounting groove, a first rack 25 slidably sleeved on the guide block 26, the first rack 25 meshing with the first gear 24; and a limiting frame 64 fixedly mounted at the bottom of the connecting plate 5 for pushing the first rack 25 down to wind up the first pull rope 22.

[0030] In this embodiment, when the moving mechanism drives the annular plate 10 to a specific height, the first rack 25 fixed inside the annular plate 10 will contact the limiting frame 64. Under the obstruction and guidance of the limiting frame 64, the first rack 25 is forced to slide downward on the guide block 26. The downward movement of the first rack 25 drives the first gear 24 to rotate. The shaft of the first gear 24 drives the first winding roller 21 to rotate, thereby winding up the first pull rope 22 and realizing the retraction of the spike needle 11.

[0031] In a further preferred embodiment of the present invention, a fixing groove is provided in the annular plate 10, and a second return spring 27 is installed in the fixing groove. A positioning block 28 is fixedly installed at one end of the second return spring 27. The positioning block 28 extends into the mounting groove and contacts one side of the first rack 25. A notch is provided on one side of the first rack 25, and the notch is adapted to the positioning block 28.

[0032] In this embodiment, during the downward movement of the first rack 25, when the notch on its side moves to a position aligned with the positioning block 28, the second reset spring 27, which was originally pressed by the side of the first rack 25, releases its elastic force, pushing the positioning block 28 into the notch of the first rack 25. This action locks the first rack 25 in its current position, preventing the spike 11 from rebounding due to external force, thereby ensuring that the first pull rope 22 is in a coiled state and the spike 11 remains retracted, preventing it from accidentally popping out and piercing the plant or hindering the operation.

[0033] In a further preferred embodiment of the present invention, the seedling bed 2 is provided with several shaking mechanisms for loosening the soil at the bottom of the seedling tray. The shaking mechanism includes: a soil loosening plate 29 disposed below the seedling tray 3; a guide rod 30 and a buffer spring 31 fixedly installed on the top of the inner wall of the seedling bed 2 for guiding the soil loosening plate 29, wherein the guide rod 30 is slidably connected to the soil loosening plate 29 and the top end of the buffer spring 31 is fixedly connected to the soil loosening plate 29; a driven rod 32 hinged to the bottom of the soil loosening plate 29; an active rod 33 rotatably installed on one side of the inner wall of the seedling bed 2 for driving the soil loosening plate 29 to move up and down, wherein the active rod 33 is hinged to the driven rod 32; a first chain drive assembly 34 disposed on the rotating shaft of the several active rods 33 for synchronously driving the several active rods 33 to rotate; and a linkage mechanism disposed on the seedling bed 2 and the support frame 14 for driving the active rods 33 to rotate.

[0034] In this embodiment, before transplanting, in order to loosen the soil at the bottom of the seedling tube, prevent the roots from sticking too much to the soil, and facilitate removal from the pot, the shaking mechanism starts to work; when the support frame 14 moves upward through the moving mechanism, it will drive the active rod 33 to rotate through the linkage mechanism. The active rod 33 drives the loosening plate 29 to shake up and down quickly along the guide rod 30 through the hinged driven rod 32. The buffer spring 31 plays the role of buffering and assisting in reset. The shaking action of the loosening plate 29 is applied to the bottom of the seedling tube (the seedling tube consists of two parts, the upper part is made of plastic and the lower part is made of elastic rubber). Through high-frequency micro-vibration, it effectively breaks up the soil clods around the roots, making the soil loose and greatly reducing the damage to the root system during transplanting. The first chain drive assembly 34 ensures that the active rods 33 under all seedling tubes move synchronously to achieve uniform soil loosening. Secondly, the first chain drive assembly 34, the second chain drive assembly 54, and the third chain drive assembly 61 are all composed of several sprockets, limit wheels, and chains. The limit wheels are located above the sprockets and mesh with the chains, effectively driving several shaking mechanisms, telescopic rods, and bidirectional screws to rotate synchronously.

[0035] In a further preferred embodiment of the present invention, the linkage mechanism includes: a protective cover 50 installed on one side of the seedling bed 2; a first differential gear 35 disposed on the rotating shaft of the drive rod 33 and on one side of the seedling bed 2, a set of the first differential gears 35 meshing together; a second differential gear 36 disposed inside the protective cover 50 and on the rotating shaft of the first differential gear 35 located on one side of the seedling bed 2, a set of the second differential gears 36 meshing together; and a second gear 37 fixedly sleeved on the rotating shaft of the second differential gear 36 located on the protective cover 50; and a second gear 37 fixedly sleeved on the rotating shaft of the second differential gear 36 located on the protective cover 50. A second rack 38 is located on one side of the second gear 37, and the second rack 38 meshes with the second gear 37; a rectangular seat 39 is fixedly installed on the top of the second rack 38, and the rectangular seat 39 extends out of the protective cover 50; a rectangular block 40 is fixedly installed on one side of the support frame 14, and the rectangular block 40 is inserted into the rectangular seat 39; a positioning rod 41 is inserted into the rectangular seat 39 and is connected to the slot of the rectangular block 40, and a magnet 42 for fixing the positioning rod 41 is installed in the slot.

[0036] In this embodiment, when the support frame 14 rises, the rectangular block 40 rises accordingly. The rectangular block 40 is connected to the rectangular seat 39 through the positioning rod 41 inserted into its slot, thereby driving the rectangular seat 39 and the second rack 38 fixed thereon to move upward together. The rise of the second rack 38 drives the second gear 37 to rotate. The power is transmitted to the shaft of the drive rod 33 through the transmission system composed of the second differential gear 36 and the first differential gear 35, causing it to rotate. Due to the setting of the differential gear, the rotation speed of the drive rod 33 is much higher than the rotation speed of the second gear 37, thereby driving the vibration mechanism to work. The magnet 42 is used to attract and fix the positioning rod 41 in the initial state to ensure reliable power transmission.

[0037] In a further preferred embodiment of the present invention, the protective cover 50 is provided with a release mechanism for pulling the positioning rod 41 to release the connection between the rectangular block 40 and the rectangular seat 39. The release mechanism includes: a mounting block 43 fixedly installed on the top of the inner wall of the protective cover 50; a second take-up roller 44 rotatably installed on the mounting block 43; a second pull rope 45 wound on the second take-up roller 44, the second pull rope 45 extending out of the protective cover 50 and fixedly connected to the positioning rod 41; and a torsion spring 46 installed on one side of the mounting block 43, one end of the torsion spring 46 being fixedly connected to the rotating shaft of the second take-up roller 44.

[0038] In this embodiment, when the support frame 14 drives the rectangular block 40 to rise to a certain height, the second pull rope 45 on the positioning rod 41 is fully straightened and tightened. At this time, the pulling force generated by the second pull rope 45 overcomes the attraction of the magnet 42, pulling the positioning rod 41 out of the slot of the rectangular block 40, thus disconnecting the rectangular block 40 from the rectangular seat 39. Then, under the restoring force of the torsion spring 46, the second winding roller 44 reverses and rewinds the second pull rope 45, pulling the positioning rod 41 back to its initial position to prepare for the next connection. This process realizes the automatic disengagement of the linkage mechanism and prevents over-running. At the same time, the reset of the second rack 38 is operated by the handle 49. Rotating the handle 49 on the shaft of the second gear 37 causes the handle 49 to drive the second gear 37 to rotate synchronously, driving the second rack 38 to slide downward.

[0039] In a further preferred embodiment of the present invention, a limiting rod 47 is installed inside the protective cover 50, and a limiting block 48 is slidably sleeved on the limiting rod 47, and the limiting block 48 is fixedly connected to the second rack 38.

[0040] In this embodiment, when the second rack 38 moves up and down, the limiting block 48 slides along the limiting rod 47, providing precise guidance for the second rack 38, preventing it from deflecting or jamming during movement, ensuring the stability of meshing with the second gear 37, thereby making the power transmission smoother and more reliable.

[0041] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a plurality of soil loosening mechanisms for loosening the soil on the surface of the seedling tray are provided above the seedling bed 2. The soil loosening mechanism includes: a set of arc-shaped rake teeth 51 disposed above the seedling tray 3; a bidirectional screw 52 rotatably mounted on the support frame 14 for adjusting the spacing of the set of arc-shaped rake teeth 51; a second slider 53 threaded onto the bidirectional screw 52; a second chain drive assembly 54 disposed on the plurality of bidirectional screws 52 for synchronously driving the plurality of bidirectional screws 52 to rotate; a second motor 55 fixedly mounted on the support frame 14 for driving the bidirectional screws 52 to rotate; and a plurality of height adjustment mechanisms disposed on the second slider 53 and the arc-shaped rake teeth 51 for adjusting the height of the arc-shaped rake teeth 51.

[0042] In this embodiment, if the soil surface becomes compacted in the later stage of seedling cultivation, a soil loosening mechanism can be used to loosen the topsoil. When in use, the second motor 55 is first started, and all bidirectional screws 52 are driven to rotate synchronously through the second chain drive assembly 54. The two second sliders 53 slide relative to each other, so that a set of arc-shaped rake teeth 51 are located inside the seedling tube. Then, the height of the arc-shaped rake teeth 51 is adjusted according to the height adjustment mechanism, so that the tips of the arc-shaped rake teeth 51 pierce the soil surface and penetrate 1-2 cm. Then, through the remote control system, the second motor 55 is set to the soil loosening mode. Subsequently, the two second sliders 53 generate relative reciprocating motion, thereby driving the set of arc-shaped rake teeth 51 at the bottom to open and close, simulating the effect of raking. By controlling the direction and speed of the second motor 55, the arc-shaped rake teeth 51 reciprocate to loosen the soil surface, effectively breaking up soil clods and improving soil permeability.

[0043] In another embodiment of the present invention, the height adjustment mechanism includes: a connecting box 56 fixedly mounted on the second slider 53; a threaded rod 57 rotatably mounted on the bottom of the connecting box 56, a threaded cylinder 58 threadedly sleeved on the threaded rod 57, the bottom end of the threaded cylinder 58 being fixedly connected to the bracket of the arc-shaped rake tooth 51; a telescopic rod 59 rotatably mounted inside the connecting box 56; second bevel gears 60 respectively fixedly sleeved on the top ends of the telescopic rod 59 and the threaded rod 57, the two second bevel gears 60 meshing with each other; a third chain drive assembly 61 respectively disposed on a plurality of the telescopic rods 59 for synchronously driving the plurality of telescopic rods 59 to rotate; and a third motor 62 fixedly mounted on one side of the connecting box 56, the output shaft of the coupling of the third motor 62 being fixedly connected to the telescopic rod 59.

[0044] In this embodiment, before loosening the soil, the depth of the arc-shaped rake teeth 51 into the soil needs to be adjusted. The third motor 62 is started, and its output shaft drives the telescopic rod 59 to rotate. The telescopic rod 59 transmits power to the threaded rod 57 through a pair of meshing second bevel gears 60. The rotation of the threaded rod 57 drives the threaded cylinder 58 to move in the vertical direction (the L-shaped rod 63 and the sliding groove structure prevent it from rotating), thereby driving the arc-shaped rake teeth 51 fixed at the bottom of the threaded cylinder 58 to rise and fall. The height of all the arc-shaped rake teeth 51 can be adjusted synchronously through the third chain drive assembly 61 to ensure that the soil loosening depth is consistent.

[0045] In another embodiment of the present invention, an L-shaped rod 63 for limiting the threaded cylinder 58 is fixedly installed at the bottom of the connecting box 56. The L-shaped rod 63 is adapted to the sliding groove on one side of the threaded cylinder 58. The connecting box 56 is composed of several box bodies and telescopic rubber cylinders 66. The telescopic rod 59 is composed of a round rod, a rectangular rod 65 and a connecting block 67. The rectangular rod 65 is slidably installed in the sliding groove of the round rod. The connecting block 67 is installed in the sliding groove and slidably connected to the limiting groove on the rectangular rod 65.

[0046] In this embodiment, the connecting box 56 consists of multiple relatively movable box bodies and an external telescopic rubber cylinder 66. This structure allows it to extend and retract as the second slider 53 adjusts the spacing, thereby protecting the internal mechanism and adapting to spacing changes. The telescopic rod 59 consists of a round rod, a rectangular rod 65 that can slide in the groove of the round rod, and a connecting block 67 that serves as a connection and limiter. This design allows the length of the telescopic rod 59 to change while transmitting torque, perfectly adapting to the axial dimension changes generated by the connecting box 56 when adjusting the spacing of the arc-shaped rake teeth 51, ensuring the stability and reliability of the entire height adjustment mechanism in dynamic operation.

[0047] In summary, compared with related technologies, this device, through its bottom and surface irrigation system, liftable branch and leaf protection mechanism, and automated root and topsoil loosening mechanism before and after transplanting, comprehensively ensures the healthy growth and physical damage protection of bamboo seedlings throughout the entire process from seedling cultivation to transplanting, significantly improving the survival rate, growth quality, and transplanting efficiency of bamboo seedlings.
