Description

Technical Field

[0001] The invention relates to the technical field of soilless cultivation of medicinal materials, in particular to a seedling breeding device for rhizome Chinese medicinal materials which is convenient for transplanting. Background Art

[0002] Rhizome Chinese herbal medicines refer to Chinese herbal medicines with roots or rhizomes as the main medicinal parts. These herbs usually have high medicinal value and are widely used in traditional Chinese medicine treatment.

[0003] Announcement No. CN118058184B discloses a root-stem Chinese medicinal material seedling breeding device that is easy to transplant, including a breeding box, a box cover is hinged at the upper end of the breeding box, a water tank is fixedly connected to the inner side of the bracket of the breeding box, a return pipe is fixedly connected to the upper left part of the water tank, the return pipe is fixedly connected to the breeding box, the breeding box and the left end of the box cover are jointly provided with a positioning mechanism, and the right end of the water tank is provided with a feeding mechanism. This application adds a lifting frame, a modular transplanting mechanism and a feeding mechanism inside the breeding box, and during use, the seedlings can be soillessly cultivated through modular breeding strips. Soilless cultivation can avoid damaging the roots during the transplanting process, so that the seedlings can be more easily transplanted, and the roots of the seedlings can be supplied with nutrients through the feeding mechanism and the slow flow mechanism, so that the seedlings can be more easily cultivated.

[0004] The growth state of the rhizomes of rhizomes of rhizome Chinese medicinal materials directly affects their medicinal value and quality. Nutrient storage: The rhizomes of rhizome Chinese medicinal materials such as ginseng, astragalus, angelica, etc. are the main nutrient storage and transportation organs. Most rhizome medicinal materials need to grow for one or two years before they can be harvested to ensure the accumulation of medicinal ingredients. The influence of soil on rhizome medicinal materials is extremely important. The soil should have good drainage and air permeability to prevent rhizomes from rotting.

[0005] The existing breeding devices have the following two conflicts when performing soilless cultivation:

[0006] Only the upper part of the medicinal material is used, and the rhizomes of the medicinal materials are allowed to grow freely in the breeding box. When the medicinal materials are closely spaced, the rhizomes will be entangled with each other. When the medicinal material seedlings are separated when transplanted into the soil, it is easy to cause damage to the rhizomes. When the medicinal materials are widely spaced, there will be differences in the number of breeding;

[0007] The rhizomes of medicinal materials are confined in barrel-shaped or square planting troughs, and the rhizomes of medicinal materials will grow along the inner wall of the planting trough. When the medicinal materials are transplanted from soilless cultivation into the soil, the root system cannot fully extend. When landfilling, the soil cannot smoothly enter the space formed by the root system, causing trouble during landfilling. Summary of the invention

[0008] One of the purposes of the present invention is to provide a rhizome Chinese medicinal material seedling breeding device that is easy to transplant, to ensure the growth state of the medicinal materials, to avoid the roots and stems from being entangled with each other when the medicinal materials are cultivated in close soilless culture, to ensure the growth state of the medicinal materials, and to make the transplanting into the soil for burial smoother, thus avoiding damage to the roots and stems.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: a seedling breeding device for rhizomes of Chinese medicinal materials that is convenient for transplanting, comprising:

[0017] The laminating plate is arranged in a ring with the central axis of the connecting frame as the center. The laminating plate is in an outer arc shape and is flexibly arranged to support the seedlings and position the seedlings;

[0018] The guide frame is arranged between the laminating plate and the connecting frame, the guide frame connects the laminating plate and the connecting frame and can control the position of the laminating plate, and the guide frame is configured in two states, one is a supporting state, in which the guide frame supports the laminating plate, and the laminating plate forms an inverted cone to support the seedlings, and the second is a contraction state, in which the guide frame drives the laminating plate to retract, and the seedlings lose the support of the laminating plate;

[0019] The card slot is arranged on the inner side of the connecting frame and limits the guide frame when the guide frame is in the retracted state.

[0020] In one or more embodiments of the present invention, the breeding unit further comprises:

[0021] The arc-shaped plate is arranged outside the connecting frame and extends outwards. The arc-shaped plate is arranged in a ring shape with the central axis of the connecting frame as the center, and the roots and stems of the seedlings extend into the inner side of the arc-shaped plate;

[0022] A frame for supporting the curved plate is arranged inside the curved plate. The curved plate is flexibly arranged. The frame changes the curvature of the curved plate. When the connecting frame moves up and down, the curvature of the curved plate is changed through the frame.

[0023] In one or more embodiments of the present invention, the frame is composed of a frame for supporting the arc plate to present an arc state, a deformation groove, a paddle and an elastic body, the elastic body is arranged inside the frame for supporting the frame, and under the supporting force of the elastic body, the frame changes the arc and can be reset;

[0024] The deformation groove is triangularly opened in the middle of the frame, and the angle of the triangle formed by the deformation groove changes when the frame is bent;

[0025] The paddle contacts the connection unit, and when the connection frame is adjusted through the connection unit, the paddle is continuously moved to change the angle of the arc plate.

[0026] In one or more embodiments of the present invention, the connecting unit includes:

[0027] The synchronous adjustment knob is rotatably arranged on the outside of the connecting frame and is coaxially arranged on the connecting frame. A clamping head is arranged inside the synchronous adjustment knob and extends into the inside of the connecting frame. The connecting frame is provided with a thread groove, and the clamping head extends into the thread groove.

[0028] The bottom of the synchronous adjustment knob is a gear meshing transmission, an idler wheel is arranged between the synchronous adjustment knobs to change the rotation direction of the synchronous adjustment knobs, and the synchronous adjustment knobs are provided with teeth meshing transmission with the idler wheel.

[0029] In one or more embodiments of the present invention, a hydraulic chamber is configured inside the synchronous adjustment knob to adjust the telescopic state of the chuck. The synchronous adjustment knob is a split design, including a coaxially arranged synchronous knob and a cover plate. A spring plate is arranged between the cover plate and the synchronous knob to support the cover plate, and the cover plate rotates to squeeze the hydraulic chamber.

[0030] In one or more embodiments of the present invention, the connecting unit further comprises:

[0031] The individual adjustment knob is rotatably arranged on the outside of the connecting frame. The individual adjustment knob is arranged on the outside of the synchronous adjustment knob and is arranged coaxially with the synchronous adjustment knob. An air chamber is arranged inside the breeding frame. A push rod is arranged on one side of the air chamber. The change of gas pressure inside the air chamber pushes the push rod to support the connecting frame to move upward.

[0032] An annular magnet is arranged inside the individual adjustment knob, and a magnetic plate is arranged correspondingly outside the air chamber. When the individual adjustment knob is rotated until the annular magnet corresponds to the magnetic plate, the air chamber is squeezed.

[0036] Through the above technical solution, the present invention has the following beneficial effects:

[0037] 1. The present invention limits the growth state of medicinal materials. During the growth of seedlings, the growth extension direction of the root system of the medicinal materials can be limited. When converting from soilless cultivation to soil cultivation, damage to the root system of the medicinal materials can be avoided, and soil filling is convenient. The restriction on root extension makes it easier to fill the soil, thereby ensuring a good transplanting state for the medicinal material seedlings.

[0038] 2. During the growth of seedlings, the root system is restricted so that the root system will stick to the outside of the curved plate. The surface curvature of the curved plate is adjusted by the action of the paddle. The root system is separated from the outer wall of the curved plate by pulling and contracting the outer wall of the curved plate. This makes transplanting more convenient and there is no need to manually separate the root system and the curved plate.

[0039] 3. Through the individual adjustment and synchronous adjustment of the breeding units, the seedlings can be transplanted according to the growth status of the seedlings. The height position of one of the breeding units can be changed individually, and the height positions of multiple breeding units can be adjusted synchronously, so that the breeders can transplant according to the growth status of the seedlings.

[0040] 4. During the up and down movement of the connecting frame, the arc block and the paddle are used to change the surface state of the arc plate, so that after the connecting frame moves upward, the arc plate and the rhizomes of the seedlings can be separated. There is no need for the breeder to use an additional scraper to separate the roots from the arc plate to avoid damage to the rhizomes.

[0063] The following will disclose multiple embodiments of the present invention with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not necessary. And if it is possible to implement, the features of different embodiments can be applied interchangeably.

[0064] Unless otherwise defined, all words (including technical and scientific terms) used herein have their usual meanings, which can be understood by those familiar with this field. Furthermore, the definitions of the above words in commonly used dictionaries should be interpreted in the content of this specification as consistent with the meanings of the relevant fields of the present invention. Unless otherwise clearly defined, these words will not be interpreted as idealized or overly formal meanings.

[0065] The relationships and terms used in the present invention are explained below:

[0066] Parallelism: The parallelism defined in the present invention is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, which allows for non-absolute parallelism due to factors such as assembly tolerance, design tolerance, and influence of structural flatness. Small angular errors are allowed. For example, an assembly error range of less than 10 degrees can be understood as a parallel relationship.

[0067] Vertical: The verticality defined in the present invention is not limited to an absolute vertical intersection (angle of 90 degrees). It allows for non-absolute vertical intersections caused by factors such as assembly tolerance, design tolerance, and influence of structural flatness. It also allows for errors in a small angle range. For example, the assembly error range of 80 to 100 degrees can be understood as a vertical relationship.

[0068] Ground: The ground defined in the present invention is not limited to a certain material or region, but only a platform for carrying the present invention, and stacking, tilting, and flatness changes are allowed. For example, cement ground, tile ground, work platform, etc. can all be interpreted as ground.

[0069] The above explanation does not completely include the relationship definitions given in the present invention, but only represents a part of the present invention.

[0070] The invention provides a rhizome Chinese medicinal material seedling breeding device which is convenient for transplanting, and is used for breeding seedlings of rhizome Chinese medicinal materials, ensuring the growth state of the rhizome, and ensuring the integrity of the rhizome of the Chinese medicinal materials when transplanting them into the soil from soilless cultivation.

[0071] See also Figure 1-2 In one embodiment, the breeding device comprises:

[0072] The machine body 1 is arranged in the shape of a cabinet or a box, the machine body 1 is placed on the ground, and the machine body 1 is arranged with a door that can be opened and closed for sealing, and at least one planting trough 2 for soilless propagation of seedlings is arranged inside the machine body 1, and the planting trough 2 is filled with nutrient solution for seedling propagation;

[0073] A temperature control system 3 is installed inside the machine body 1 and is used to change and control the growth temperature and humidity changes of the seedlings inside the machine body 1. The temperature control system 3 can change the temperature change of the nutrient solution;

[0074] A breeding rack 4 is installed on the upper part of the planting trough 2 and is used to limit the position of the seedlings. The breeding rack 4 is equipped with a plurality of breeding units 41 for placing the seedlings. The breeding units 41 limit the arc-shaped extension of the seedlings outward with the central axis as the center, and the growth position of the seedling rhizome is limited by the breeding units 41;

[0075] The connection unit 5 is arranged inside the breeding frame 4. Under the connection of the connection unit 5, the breeding unit 41 can be adjusted individually or multiple breeding units 41 can be adjusted synchronously. The connection unit 5 is equipped with two adjustment knobs corresponding to the individual adjustment and synchronous adjustment of the breeding unit 41.

[0076] In one practicable manner, the temperature control system 3 is set as a conventional setting, which does not affect the growth position of the seedling rhizome and the detachment of the root seedling. Optionally, the temperature control system 3 is a conventional setting of: a heating tube, a humidifier, and a temperature and humidity detection sensor. Another option is that the temperature control system 3 is: a nutrient solution circulation unit, a heating unit, a humidifier, and a temperature and humidity detection sensor. When in use, the heating unit changes the temperature of the nutrient solution during the circulation of the nutrient solution. The present invention does not limit the specific implementation scheme of the temperature control system 3, and it only needs to be able to control the breeding environment of the seedlings inside the body 1.

[0077] Since the different seeds selected during the breeding process correspond to different growth states of the seedlings, when the seedlings grow to the stage where they need to be transplanted, in order to facilitate the transplantation of single or multiple seedlings, the breeding unit 41 can be controlled through individual and synchronous adjustments, which makes it more convenient to handle the seedlings.

[0078] See also Figure 3-4 In one embodiment, the breeding frame 4 includes an adjustment frame 6 for changing the height of the seedlings inside the planting trough 2, and a guide rail 7 for limiting the up and down movement of the breeding frame 4 is arranged between the adjustment frame 6 and the breeding frame 4. The guide rail 7 is installed on the outside of the planting trough 2, and the breeding frame 4 is embedded on the outside of the guide rail 7. A support unit 8 is arranged between the breeding frame 4 and the planting trough 2, and the support unit 8 changes the height of the breeding frame 4 compared to the planting trough 2.

[0079] In one feasible manner, since the breeding device is not targeted at breeding a certain type of Chinese medicinal material seedlings, and the growth length of the rhizomes of each Chinese medicinal material seedling is different, the adjustable breeding rack 4 can better adapt to different Chinese medicinal material seedlings.

[0080] Optionally, the supporting unit 8 supports the breeding frame 4 with bolts, and the height position of the breeding frame 4 can be changed by adjusting the length of the bolts on both sides of the breeding frame 4.

[0081] Alternatively, the support unit 8 is an electric telescopic rod to support the breeding rack 4. The extension and retraction of the electric telescopic rod can remotely change the height of the breeding rack 4 at any time according to the status without opening the cabinet.

[0082] See also Figure 5-8 In one embodiment, the breeding unit 41 comprises:

[0083] A connecting frame 411 is connected to the breeding frame 4 and can move up and down relative to the breeding frame 4;

[0084] The laminating plate 412 is arranged in a ring shape with the central axis of the connecting frame 411 as the center. The laminating plate 412 is in an outer arc shape and is flexibly arranged to support the seedlings and position the seedlings;

[0085] The guide frame 413 is arranged between the laminating plate 412 and the connecting frame 411. The guide frame 413 connects the laminating plate 412 and the connecting frame 411 and can control the position of the laminating plate 412. The guide frame 413 is configured in two states, one of which is a supporting state, in which the guide frame 413 supports the laminating plate 412, and the laminating plate 412 forms an inverted cone to support the seedlings. The second state is a contraction state, in which the guide frame 413 drives the laminating plate 412 to retract, and the seedlings lose the support of the laminating plate 412.

[0086] The slot 414 is provided inside the connecting frame 411 to limit the guide frame 413 when the guide frame 413 is in the retracted state.

[0087] In one feasible method, during the seedling breeding process, the seedlings are supported by the bonding plate 412, and the bonding plate 412 is set to be flexible. During the growth of the seedlings, the bonding plate 412 is prevented from restricting the growth of the seedlings. After the seedlings are positioned, changing the height of the connecting frame 411 relative to the breeding frame 4 can also synchronously drive the position of the seedlings to change.

[0088] The guide frame 413 is hinged to the connecting frame 411 and can swing relative to the connecting frame 411. The swing of the guide frame 413 is used to change the position of the bonding plate 412. When the seedlings grow, the bonding plate 412 is squeezed to bend.

[0089] See also Figure 6-8 In one embodiment, the breeding unit 41 further comprises:

[0090] The arc plate 415 is arranged outside the connecting frame 411 and extends outward. The arc plate 415 is arranged in a ring shape with the central axis of the connecting frame 411 as the center, and the roots of the seedlings extend into the inner side of the arc plate 415;

[0091] A skeleton 416 for supporting the arc plate 415 is disposed inside the arc plate 415 . The arc plate 415 is flexibly arranged. The skeleton 416 changes the curvature of the arc plate 415 . When the connecting frame 411 moves up and down, the curvature of the arc plate 415 is changed through the skeleton 416 .

[0092] In one feasible method, the growth of the rhizomes of the seedlings is restricted by the curved plate 415, so the rhizomes will fit the curved plate 415 and adhere to the outer wall of the curved plate 415, resulting in adhesion between the rhizomes and the curved plate 415. The skeleton 416 is used to change the curvature of the curved plate 415, which can cause the outer wall of the curved plate 415 to deform, stretch or shrink. During stretching and shrinkage, the rhizomes of the seedlings are separated from the curved plate 415, and damage to the root system of the seedlings can be avoided when transplanting the seedlings.

[0093] See also Fig.15 In one embodiment, the skeleton 416 is composed of a frame 4161 for supporting the arc plate 415 to present an arc state, a deformation groove 4162, a paddle 4163 and an elastic body 4164. The elastic body 4164 is arranged inside the frame 4161 to support the frame 4161. Under the supporting force of the elastic body 4164, the frame 4161 can be reset after changing the arc.

[0094] The deformation groove 4162 is triangularly formed and opened in the middle of the frame 4161. When the frame 4161 is bent, the angle of the triangle formed by the deformation groove 4162 changes.

[0095] The paddle 4163 contacts the connection unit 5 , and when the connection frame 411 is adjusted through the connection unit 5 , the paddle 4163 is continuously moved to change the angle of the arc plate 415 .

[0096] In an optional embodiment, the skeleton 416 supports the arc plate 415 to ensure the stable bending state of the arc plate 415. The paddle 4163 extends into the interior of the frame 4161 and bends when the paddle 4163 is pushed, thereby changing the surface bending state of both sides of the arc plate 415. After the arc plate 415 is bent, there is a stretching of the surface area of ​​the arc plate 415, thereby allowing the roots to detach from the surface of the arc plate 415.

[0097] The formation of the deformation groove 4162 gives the frame 4161 a larger swing range, so that the curvature can be changed significantly, so that the surface can obtain a greater deformation, ensuring the detachment effect of the root system.

[0098] See also Figure 9-11 In one embodiment, the connection unit 5 comprises:

[0099] The synchronous adjustment knob 50 is rotatably arranged outside the connecting frame 411 and is coaxially arranged with the connecting frame 411. A clamping head 51 is arranged inside the synchronous adjustment knob 50 and extends into the connecting frame 411. The connecting frame 411 is provided with a thread groove 52. The clamping head 51 extends into the thread groove 52. The synchronous adjustment knob 50 is rotated to change the height of the connecting frame 411 through the clamping head 51.

[0100] The bottom of the synchronous adjustment knob 50 is a gear meshing transmission. An idler wheel 53 is arranged between the synchronous adjustment knobs 50 to change the rotation direction of the synchronous adjustment knob 50. The synchronous adjustment knob 50 is provided with teeth 54 that mesh with the idler wheel 53 for transmission.

[0101] In one feasible method, the rotation of the synchronous adjustment knob 50 will change the position of the clamping head 51, and the interior of the connecting frame 411 is set as a threaded groove 52, and the connecting frame 411 is restricted by the breeding frame 4. Through the cooperation between the clamping head 51 and the threaded groove 52, the height position of the connecting frame 411 can be adjusted. In order to facilitate the control of the synchronous adjustment knob 50 at different positions, the idler wheel 53 is configured to ensure that the rotation direction of the synchronous adjustment knob 50 is consistent.

[0102] See also Figure 10-11 In one embodiment, a hydraulic chamber 501 is configured inside the synchronous adjustment knob 50 to adjust the telescopic state of the clamping head 51. The synchronous adjustment knob 50 is a split design, including a coaxially arranged synchronous knob 502 and a cover plate 503. A spring 504 is arranged between the cover plate 503 and the synchronous knob 502 to support the cover plate 503. The cover plate 503 rotates to squeeze the hydraulic chamber 501.

[0103] In one practicable manner, the rotation of the cover plate 503 compresses the spring piece 504, and the cover plate 503 pushes the medium inside the hydraulic chamber 501 to move, pushing the chuck 51 outward, so that the chuck 51 is inserted into the thread groove 52, and the connection frame 411 is moved up and down by utilizing the restrictions of the chuck 51 and the thread groove 52. Under the action of the spring piece 504, the cover plate 503 can be reset. In order to be able to synchronously control multiple chucks 51, the teeth 54 are arranged on the outside of the cover plate 503 and mesh with the idler wheel 53 for transmission.

[0104] The cover plate 503 extends into the hydraulic chamber 501 . When the cover plate 503 rotates, it can squeeze the medium in the hydraulic chamber 501 . The supporting force of the spring 504 on the cover plate 503 is smaller than the resistance of the medium in the hydraulic chamber 501 pushing the chuck 51 , which is smaller than the rotation resistance of the synchronization knob 502 .

[0105] See also Figure 12-14 In one embodiment, the connection unit 5 further includes:

[0106] The individual adjustment knob 55 is rotatably arranged on the outside of the connecting frame 411. The individual adjustment knob 55 is arranged on the outside of the synchronous adjustment knob 50 and is arranged coaxially with the synchronous adjustment knob 50. An air chamber 56 is arranged inside the breeding frame 4. A push rod 59 is arranged on one side of the air chamber 56. The change of gas pressure inside the air chamber 56 pushes the push rod 59 to support the connecting frame 411 to move upward.

[0107] An annular magnet 57 is disposed inside the individual adjustment knob 55 , and a magnetic plate 58 is correspondingly disposed outside the air chamber 56 . When the individual adjustment knob 55 is rotated until the annular magnet 57 corresponds to the magnetic plate 58 , the air chamber 56 is squeezed.

[0108] In one feasible method, through the cooperation of the annular magnet 57 and the magnetic plate 58, after the individual adjustment knob 55 is rotated to a specified position, the air chamber 56 is squeezed, so that the air inside the air chamber 56 changes the extension length of the push rod 59, and the push rod 59 is used to support the connecting frame 411, so that the connecting frame 411 moves outward, so that a single breeding unit 41 can be controlled and the height of the connecting frame 411 can be changed.

[0109] See also Fig.14 In one embodiment, a plurality of arc blocks 510 for supporting the paddles 4163 are arranged on the inner side of the breeding frame 4. The paddles 4163 fit the outer wall of the arc blocks 510 and are supported by the arc blocks 510. The paddles 4163 are arranged with uniform intervals and staggered positions. When the connecting frame 411 moves up and down, the arc blocks 510 squeeze the paddles 4163.

[0110] In one feasible manner, the setting of the arc block 510 can form a support for the paddle 4163, and the paddle 4163 is attached to the outer walls of the upper and lower sides of the arc block 510. When the connecting frame 411 moves up and down, the arc plate 415 moves up and down with the connecting frame 411. Synchronously, the arc block 510 squeezes the paddle 4163 to make the paddle 4163 swing, and the outer wall of the arc plate 415 is pulled, so that the root system is separated from the arc plate 415.

[0111] In one embodiment, the breeding frame 4 restricts the connecting frame 411, and the connecting frame 411 can only move up and down relative to the breeding frame 4, and adjacent connecting frames 411 are staggered;

[0112] The air chamber 56 is set as an opening, and the air chamber 56 is an elastic compressible cavity. The magnetic plate 58 is fixed to the outer wall of the air chamber 56. The annular magnet 57 controls the magnetic plate 58 to squeeze the air chamber 56. The air chamber 56 is provided with an air outlet, and the push rod 59 is inserted into the air chamber 56 through the air outlet. The air chamber 56 fits tightly with the push rod 59 through its own elasticity.

[0113] In one feasible manner, the air chamber 56 is set to be elastic and have only one outlet to avoid gas leakage. In order to further ensure that the medium inside the air chamber 56 does not leak, the gas can be replaced with a liquid medium to further ensure the stability of the medium inside the air chamber 56.

[0114] Due to the elastic setting of the air chamber 56, the repulsive force between the annular magnet 57 and the magnetic plate 58 is used to control the magnetic plate 58 to compress the air chamber 56. In this state, the air chamber 56 is only confined to the inside of the breeding rack 4 and is not fixed to the breeding rack 4, so that the air chamber 56 is squeezed.

[0115] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
