Description

Technical Field

[0001] The invention belongs to the technical field of traditional Chinese medicine planting, and in particular relates to a three-dimensional cultivation device for planting picrorhizome. Background Art

[0002] As a traditional Chinese medicinal material, Picrorhizoma Coptidis has a continuously growing market demand due to its high medicinal value. However, wild Picrorhizoma Coptidis resources are decreasing due to over-harvesting and other reasons, and artificial cultivation has become an important way to meet market demand.

[0003] At present, flat seedbeds are mostly used for the cultivation of Picrorhizoma Ceratitis seedlings, and the number of seedlings that can be planted per unit area is limited. In the context of increasingly tight land resources, this cultivation method limits the planting scale and yield of Picrorhizoma Ceratitis. In flat cultivation, the seedlings are distributed more dispersedly, and a large amount of manpower and time are required for daily management work such as watering, fertilizing and prevention. At the same time, due to the large distance between plants, it is not conducive to real-time monitoring and unified management of the growth status of seedlings. The root system of the seedlings grows more disorderly and is closely integrated with the soil. During transplantation, the root system of the seedlings is easily damaged, affecting the survival rate and later growth of the seedlings. Moreover, it takes a lot of effort to separate the seedlings from the seedbed during the transplantation process, which increases labor intensity and cost. Summary of the invention

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The embodiment of the present invention provides a three-dimensional cultivation device for planting Picrorhizoma Coptidis, such as Figure 1-10 As shown, the three-dimensional cultivation device for planting Coptis chinensis includes: a planting frame 1 that can be erected in a planting shed, a plurality of cultivation troughs 2 are placed on the planting frame 1 from top to bottom, and a liftable net basket 7 is provided in the cultivation trough 2, and a plurality of pull-out and detachable cultivation frames 8 are provided in the net basket 7; a base plate 3 is provided on one side of the planting frame 1, and a water tank 4 for containing irrigation liquid is provided on the base plate 3; a water supply pipe 6 fixedly connected to the water tank 4, and the water supply pipe 6 is used to connect a water supply device to replenish water into the water tank 4; a lifting mechanism is provided on the planting frame 1 and the net basket 7, and the lifting mechanism is used to regulate the lifting of the net basket 7; and an irrigation mechanism is provided on the base plate 3 for pumping water into the cultivation trough 2.

[0021] In this embodiment, the planting frame 1 can be erected in the planting shed, and a plurality of cultivation troughs 2 are placed thereon from top to bottom. In actual use, the picrorhizoma serrata seedlings are planted in the cultivation frame 8 in the net basket 7. The cultivation frame 8 can be pulled out and disassembled to facilitate subsequent transplanting. The cultivation frame 8 is provided with a partition to separate the space for holding the culture soil for planting picrorhizoma serrata. The separation can prevent the roots of similar picrorhizoma serrata plants from being connected together. When transplanting, the soil can be removed together with the compacted culture soil. The provision of a plurality of cultivation troughs 2 expands the planting space in the vertical direction, increases the number of plantings per unit area, effectively solves the problem of the limited number of seedlings planted per unit area in plane cultivation, improves the utilization rate of land resources, and provides conditions for expanding the scale of picrorhizoma serrata planting. The liftable net basket 7 can be raised and lowered under the action of the lifting mechanism, which is convenient for the operator to separate the net basket 7 from the cultivation trough 2, reducing the labor intensity. Compared with the scattered layout of seedlings in plane cultivation, this centralized lifting is convenient for transplantation and management. The water tank 4 provided on the base plate 3 is used to hold the irrigation liquid, and the water supply pipe 6 fixedly connected to the water tank 4 is used to connect the water supply equipment to replenish water into the water tank 4. During use, the water tank 4 is replenished to a suitable water level through the water supply pipe 6, and the water tank 4 provides a water reserve for subsequent irrigation. Compared with the decentralized watering method in plane cultivation, this setting can realize the centralized management and allocation of irrigation water, reduce the waste of manpower in the watering process, and improve the efficiency of watering. In addition, a moisturizing pad is specially provided in the cultivation trough 2. The moisturizing pad has good water absorption and moisturizing properties, can effectively maintain the humidity of the cultivation environment, and create suitable growth conditions for the picrorhizoma serrata seedlings. At the same time, air holes are carefully arranged on the cultivation frame 8 and the net basket 7. These air holes can promote air circulation, ensure that the roots of the seedlings can obtain sufficient oxygen, and are conducive to the healthy growth of the seedlings, further improving the scientific nature of picrorhizoma serrata planting; The lifting mechanism is arranged on the planting frame 1 and the net basket 7, and is used to control the lifting and lowering of the net basket 7. When the seedlings need to be transplanted, the net basket 7 can be lifted by the lifting mechanism, so that the operator can pull out the cultivation frame 8, and then take out the seedlings together with part of the soil. Due to the partition design of the cultivation frame 8, the roots of the seedlings will not be overly entangled and tightly attached, which effectively avoids root damage, improves the survival rate and later growth quality of the seedlings, and reduces the difficulty of separating the seedlings from the seedbed during transplantation, reducing labor intensity and cost. The irrigation mechanism arranged on the base plate 3 is used to pump water into the cultivation trough 2. The mechanism can automatically or manually transport the water in the water tank 4 to the cultivation trough 2 according to the growth needs of the seedlings, so as to achieve precise irrigation. Compared with the manual scattered irrigation during plane cultivation, it saves manpower and time, improves the accuracy and efficiency of management, and provides strong support for the sustainable development of the Picrorhizoma Coptidis planting industry.

[0022] In a further preferred embodiment of the present invention, the lifting mechanism includes: a mounting frame 9 fixedly mounted on the top of the planting frame 1, a winding drum 10 symmetrically rotatably mounted in the mounting frame 9 through a bearing, and a connecting rod 12 is assembled on the shafts of the winding drums 10 close to each other through a coupling; a steel wire rope 11 is arranged on the winding drum 10, a first rope ring 13 is fixed to the bottom end of the steel wire rope 11, and the first rope ring 13 is fixedly connected to the net basket 7 located at the top of the planting frame 1; a second rope ring 16 symmetrically fixedly mounted on two adjacent net baskets 7 in the lower layer, and a corresponding suspension rope 17 for pulling is fixedly mounted on the second rope ring 16; a first guide rod 14 symmetrically fixedly mounted on the inner walls on both sides of the planting frame 1, a guide frame 15 is slidably sleeved on the first guide rod 14, and the guide frame 15 is fixedly connected to the net basket 7.

[0023] In this embodiment, in the lifting mechanism, the mounting frame 9 is fixedly installed on the top of the planting frame 1, providing a stable support foundation for the entire lifting mechanism. The winding disc 10 is symmetrically and rotatably installed in the mounting frame 9 through bearings, so that the winding disc 10 can rotate flexibly, which provides convenience for the subsequent retraction and release of the wire rope 11. The connecting rod 12 is assembled on the shafts of the winding discs 10 that are close to each other through a coupling. This connection method ensures that the two winding discs 10 can rotate synchronously, thereby making the lifting process smoother. The first guide rod 14 is symmetrically and fixedly installed on the inner walls on both sides of the planting frame 1, providing a guide for the lifting and lowering of the net basket 7, and preventing the net basket 7 from shaking or deflecting during the lifting process. The guide frame 15 is slidably mounted on the first guide rod 14 and fixedly connected to the net basket 7, further enhancing the stability and reliability of the lifting and lowering of the net basket 7. Compared with the device without a guide structure, this design can better protect the seedlings and prevent damage to the seedlings caused by shaking; The steel wire rope 11 is arranged on the winding drum 10, and a first rope ring 13 is fixed at the bottom end thereof. The first rope ring 13 is fixedly connected to the net basket 7 located at the top of the planting frame 1. When the net basket 7 needs to be lifted, the steel wire rope 11 is wound around the winding drum 10 by rotating the winding drum 10, thereby driving the top net basket 7 to rise. Second rope rings 16 are symmetrically fixedly installed on the two adjacent net baskets 7 of the lower layer, and a lifting rope 17 is fixedly installed on the corresponding second rope rings 16. The lifting rope 17 is used to pull the net basket 7 of the lower layer. When the top net basket 7 rises, the pulling action of the lifting rope 17 can drive the net baskets 7 of the lower layer to rise in turn. This connection method enables the entire group of net baskets 7 to be lifted and lowered synchronously, which greatly improves the operating efficiency and reduces the operating time and labor costs compared to the method of lifting a single net basket 7 separately. When transplanting the Coptis chinensis seedlings or performing other operations that require lifting the net basket 7, the operator can rotate the connecting rod 12 through external force to drive the two winding discs 10 to rotate synchronously, realize the retraction and release of the wire rope 11, and then regulate the lifting and lowering of the net basket 7. Since the various components of the lifting mechanism work together, the lifting height of the net basket 7 can be accurately controlled, which is convenient for the operator to pull out the cultivation frame 8 and take out the seedlings. In this process, since the net basket 7 is smoothly lifted and lowered under the action of the first guide rod 14 and the guide frame 15, and each net basket 7 moves synchronously, it effectively avoids damage to the seedling root system caused by shaking or collision during the lifting process, and improves the survival rate and later growth quality of the seedlings. At the same time, the design of this lifting mechanism makes the transplanting process more convenient and efficient, reduces labor intensity and cost, and provides more powerful support for the planting and management of Coptis chinensis.

[0024] In a further preferred embodiment of the present invention, the irrigation mechanism includes: an installation box 18 fixedly mounted on the base plate 3, a water guide shell 19 is assembled in the installation box 18 through a support; a rotating shaft 20 rotatably mounted in the water guide shell 19 through a sealed bearing, an impeller 21 is fixedly mounted on the rotating shaft 20; a water outlet pipe 22 fixedly connected to the water guide shell 19, a plurality of diversion pipes 23 are fixedly connected to the water outlet pipe 22, and the water outlet end of the diversion pipe 23 is connected to the cultivation trough 2; a water suction pipe 24 fixedly connected to the water guide shell 19 and the water tank 4.

[0025] In this embodiment, in the irrigation mechanism, the installation box 18 is fixedly installed on the base plate 3, providing a stable installation foundation for the entire irrigation mechanism. The water guide shell 19 is assembled in the installation box 18 through a support to ensure that the water guide shell 19 can be placed firmly. The rotating shaft 20 is rotatably installed in the water guide shell 19 through a sealed bearing. This installation method ensures that the rotating shaft 20 can rotate flexibly. At the same time, the sealed bearing can effectively prevent water leakage and ensure the normal operation of the irrigation mechanism. The impeller 21 is fixedly installed on the rotating shaft 20. When the rotating shaft 20 rotates, the impeller 21 can rotate accordingly to provide power for the flow of water. The water outlet pipe 22 fixedly connected to the water guide shell 19 and the multiple diversion pipes 23 fixedly connected to the water outlet pipe 22 form a complete water delivery channel to transport the water in the water guide shell 19 to each cultivation trough 2. The water extraction pipe 24 fixedly connected to the water guide shell 19 and the water tank 4 realizes the connection between the water tank 4 and the water guide shell 19, providing a channel for extracting water from the water tank 4. The reasonable installation and connection of these components make the entire irrigation mechanism more compact and stable compared to the traditional irrigation structure, and improve the reliability of irrigation.

[0026] During irrigation, the rotating shaft 20 is driven to rotate by external force, driving the impeller 21 to rotate. The rotation of the impeller 21 forms suction in the water guide shell 19, and the water in the water tank 4 is pumped into the water guide shell 19 through the pumping pipe 24. After the water enters the water guide shell 19, it is evenly transported to each cultivation trough 2 through the outlet pipe 22 and the diversion pipe 23 under the push of the impeller 21. Compared with traditional gravity irrigation or simple water pumping, this water pumping and water delivery method driven by the impeller can more accurately control the flow and pressure of water, ensure that each cultivation trough 2 can get the right amount of water, meet the needs of different growth stages of the picrorhizoma serrata seedlings, and improve the accuracy and efficiency of irrigation. In addition, in order to further optimize the irrigation process and achieve more scientific and accurate water management, a humidity sensor is deliberately inserted into the soil for cultivating the picrorhizoma serrata seedlings. The humidity sensor can detect soil moisture in real time and accurately, and feed the detection data back to the system so that the amount and frequency of irrigation can be adjusted in time according to the actual soil moisture conditions, further improving the intelligence level and practicality of the entire irrigation system.

[0027] The operator can flexibly adjust the amount of water and the frequency of irrigation by controlling the rotation speed and time of the rotating shaft 20. Due to the coordinated work of the various components of the irrigation mechanism, it is possible to achieve automated or semi-automated irrigation operations, greatly reducing the workload of manual operations and reducing labor intensity. At the same time, this precise irrigation method avoids the problem of poor growth of seedlings caused by excessive or insufficient watering, which is conducive to improving the survival rate and growth quality of the Picrorhizoma Coptidis seedlings. In addition, the connection design of multiple shunt pipes 23 and the cultivation trough 2 allows each planting layer of the entire three-dimensional cultivation device to be evenly irrigated, improving the uniformity and convenience of planting management, and providing effective technical support for the large-scale planting of Picrorhizoma Coptidis.

[0028] In a further preferred embodiment of the present invention, a rotating rod 26 is rotatably installed in the water tank 4 through a sealed bearing, and a stirring blade 27 for stirring water and fertilizer is fixedly installed on the rotating rod 26. A sewage pipe for draining water during cleaning is fixedly connected to one side of the water tank 4, and a water valve is provided on the sewage pipe.

[0029] In this embodiment, the rotating rod 26 in the water tank 4 is rotatably installed through a sealed bearing, which not only ensures the flexible rotation of the rotating rod 26, but also prevents the liquid in the water tank 4 from leaking, ensuring the normal use of the water tank. The stirring blade 27 is fixed to the rotating rod 26, and when the rotating rod 26 rotates, the stirring blade 27 stirs the water and fertilizer in the water tank 4. One side of the water tank 4 is fixedly connected to the sewage pipe, and the sewage pipe is equipped with a water valve to control the opening and closing, which is convenient for drainage. These components are reasonably installed and connected, making the water tank 4 more functional and practical, and providing better support for the stable operation of the irrigation system; when in use, the external force drives the rotating rod 26 to drive the stirring blade 27 to rotate, fully stir the water and fertilizer, make the nutrients uniform, and provide balanced nutrition for the seedlings. When cleaning the water tank 4, open the water valve, and the sewage and impurities are discharged through the sewage pipe, which is easy to operate. Compared with a water tank without stirring and sewage discharge functions, this setting can better ensure the quality of irrigation liquid, reduce seedling growth problems, and improve irrigation quality and effect.

[0030] In a further preferred embodiment of the present invention, the cultivation trough 2 is fixedly connected to a drainage pipe 28, the outlet end of the drainage pipe 28 is fixedly connected to a confluence pipe 29, and the diversion pipe 23 and the drainage pipe 28 are respectively provided with a first solenoid valve 25 and a second solenoid valve 30 for controlling the on-off of the pipeline.

[0031] In this embodiment, a drain pipe 28 is fixedly connected to the cultivation trough 2, which provides a discharge channel for excess water in the cultivation trough 2. The water outlet end of the drain pipe 28 is fixedly connected to a confluence pipe 29, which can collect the water discharged from each cultivation trough 2 for centralized treatment. A first solenoid valve 25 is provided on the shunt pipe 23, and a second solenoid valve 30 is provided on the drain pipe 28. These two solenoid valves are used to control the on-off of the shunt pipe 23 and the drain pipe 28, respectively. Their installation positions are reasonable and the connection method is stable, so that the entire drainage system and the irrigation system cooperate with each other to form a complete liquid transportation and discharge system. Compared with cultivation devices without these drainage components, this setting can better control the moisture content in the cultivation trough 2, provide a more suitable growth environment for the picrorhizome seedlings, and also improve the practicality and functionality of the entire device; During the irrigation process, when it is necessary to supply water to the cultivation trough 2, the operator can open the first solenoid valve 25 and close the second solenoid valve 30, and the water and fertilizer in the water tank 4 are evenly transported to the cultivation trough 2 through the shunt pipe 23. When there is too much water in the cultivation trough 2, the operator can close the first solenoid valve 25 and open the second solenoid valve 30, and the excess water in the cultivation trough 2 flows into the conduit 29 through the drain pipe 28. This method of controlling the on-off of the pipeline through the solenoid valve can accurately control the flow direction and flow rate of water, and realize the dynamic management of the water in the cultivation trough 2. Compared with the traditional drainage method, this setting can discharge excess water more timely and effectively, avoid problems such as root rot of seedlings caused by water accumulation, and improve the survival rate and growth quality of Picrorhizon seedlings; The operator can flexibly control the opening and closing of the first solenoid valve 25 and the second solenoid valve 30 according to the growth requirements and actual conditions of the picrorhizoma serrata seedlings. This flexible operation mode not only facilitates daily planting management, but also greatly reduces the errors of manual judgment and operation, and reduces labor intensity. At the same time, the setting of the drain pipe 28 and the conduit 29 enables the discharged water to be centrally processed and can be recycled and reused as needed, thereby improving the utilization rate of water resources. In addition, by accurately controlling the moisture content in the cultivation trough 2, a more stable and suitable growth environment is provided for the picrorhizoma serrata seedlings, which is conducive to improving the yield and quality of the picrorhizoma serrata, and further improving the economic and social benefits of the entire three-dimensional cultivation device.

[0032] In a further preferred embodiment of the present invention, brackets are symmetrically fixedly installed on the inner walls of both sides of the planting frame 1, and guide wheels 31 for limiting and guiding the steel wire rope 11 are rotatably installed on the brackets.

[0033] In this embodiment, brackets are symmetrically fixedly installed on the inner walls on both sides of the planting frame 1, and these brackets provide a stable support structure for the installation of the guide wheel 31. The guide wheel 31 is rotatably installed on the bracket, so that the guide wheel 31 can rotate flexibly, while ensuring its stability during operation. The guide wheel 31 is used to limit and guide the wire rope 11, and its installation position matches the running path of the wire rope 11, which can effectively constrain the movement trajectory of the wire rope 11. This installation method cooperates with the entire planting frame 1 and other components in the lifting mechanism to form a more complete lifting system. Compared with the device without the guide wheel 31 limiting and guiding, this setting can better ensure the stability and reliability of the wire rope 11 in the process of lifting the basket 7, reduce the risk of the wire rope 11 being offset or off the track, and thus provide a stronger guarantee for the normal operation of the entire three-dimensional cultivation device.

[0034] In a further preferred embodiment of the present invention, a plurality of transverse plates are fixedly mounted on the planting frame 1 , and the transverse plates are used to support the cultivation troughs 2 . A positioning plate is fixedly mounted on the bottom of the planting frame 1 .

[0035] In this embodiment, a plurality of transverse plates are fixedly installed on the planting rack 1, and the positions and layouts of these transverse plates are carefully designed to provide a stable bearing platform for the cultivation trough 2. The transverse plates are connected to the planting rack 1 in a reliable fixing manner to ensure that the corresponding weight and pressure can be withstood during the growth of the cultivation trough 2 and the seedlings. At the same time, a positioning plate is fixedly installed at the bottom of the planting rack 1, and the positioning plate is firmly connected to the planting rack 1, providing a stable support foundation for the entire planting rack 1. The installation method of the transverse plates and the positioning plates enables the planting rack 1, the cultivation trough 2 and other related components to form a stable overall structure. Compared with a planting device without transverse plates and positioning plates, this setting can better ensure the stability of the cultivation trough 2 and the reliability of the planting rack 1 during use, providing a solid hardware foundation for the growth of the Picrorhizoma Cerevisiae seedlings.

The top of the feeding pipe 5 is fixedly connected to a hopper 60, and a detachable cover is provided on the hopper 60.

[0037] In this embodiment, a feeding pipe 5 is fixedly connected to the top of the water tank 4. This connection method is firm and stable, and provides a special channel for adding fertilizer to the water tank 4. A hopper 60 is fixedly connected to the top of the feeding pipe 5. The hopper 60 provides a large space for the fertilizer to be put in, which is convenient for the operator to perform the feeding operation. A detachable cover plate is provided on the hopper 60, which is connected to the hopper 60 through a reasonable connection method, which can ensure that it is convenient to open when adding materials, and can effectively close the hopper 60 when not in use to prevent dust, debris, etc. from entering the water tank 4. The installation and connection of the feeding pipe 5, the hopper 60 and the cover plate cooperate with the water tank 4 and the entire irrigation system to form a complete fertilizer addition system. Compared with a device without a special feeding component, this setting can add fertilizer to the water tank 4 more conveniently and hygienically, providing convenient conditions for subsequent water-fertilizer mixing and irrigation.

[0039] In this embodiment, at the bottom of the base plate 3, support legs are symmetrically fixedly installed. This symmetrical installation method can evenly disperse the weight borne by the base plate 3 and the entire device, ensuring the stability of the device. Foot pads are fixedly installed at the bottom of the support legs, which are in contact with the ground, increasing the friction between the support legs and the ground, and preventing the device from sliding or tilting during use. At the same time, a collection box is provided on one side of the planting rack 1, and the collection box corresponds to the position of the manifold 29, which is used to collect the water discharged from the manifold 29. The layout of the collection box and the entire device is reasonable and tightly connected, forming a complete water collection system. The installation and connection of the support legs, foot pads and collection boxes cooperate with the base plate 3, the planting rack 1 and other components to enhance the stability and practicality of the entire three-dimensional cultivation device. Compared with devices without these components, this setting can better ensure the stable placement of the device and the effective collection of the discharged water, providing better hardware conditions for the planting of Picrorhizoma.

[0040] In a further preferred embodiment of the present invention, a flushing pipe 61 for supplying water to the hopper 60 is fixedly connected to the water guide shell 19, and a third solenoid valve 62 for controlling the on-off of the pipeline is provided on the flushing pipe 61.

[0041] In this embodiment, a flushing pipe 61 is fixedly connected to the water guide shell 19 to supply water to the hopper 60, forming a water supply channel to provide a water source for flushing the hopper 60. The flushing pipe 61 is provided with a third solenoid valve 62 to control the on-off, and the installation position is reasonable, which is convenient for controlling the water flow. The two cooperate with the water guide shell 19, the hopper 60 and other parts of the device to improve the functional system of the three-dimensional cultivation device. Compared with the device without such a setting, this design can more conveniently clean the hopper 60, ensure its cleanliness, and provide better conditions for adding fertilizer to the water tank 4; When cleaning the residue in the feeding pipe 5, the operator opens the third solenoid valve 62, and the water in the water guide shell 19 flows into the hopper 60 and the feeding pipe 5 through the flushing pipe 61 to flush the residual fertilizer. After cleaning, the solenoid valve is closed to stop the water. This method is more efficient and convenient than traditional manual cleaning or the situation without special measures, which can reduce the workload and labor intensity, ensure the cleaning effect, and avoid impurities affecting the quality of fertilizer and the mixing of water and fertilizer.

[0042] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, a driving mechanism for driving the winding disk 10 to rotate is provided on the installation box 18, and the driving mechanism includes: a protective shell 63 fixed to the top of the installation box 18 by welding, a motor 32 and a speed regulating mechanism 33 are provided in the protective shell 63, and the input shaft of the speed regulating mechanism 33 is fixedly connected to the output shaft of the motor 32 through a coupling; a second guide rod 38 fixedly installed in the protective shell 63, a mounting plate 35 is slidably sleeved on the second guide rod 38, a gear cylinder 36 is rotatably installed on the mounting plate 35 through a bearing, a gear rod 34 for transmission is provided in the gear cylinder 36, and the gear rod 34 is connected to the speed regulating mechanism 33 through a coupling. 3 is fixedly connected; a first transmission rod 40 rotatably mounted in the protective shell 63 through a bearing seat, one end of the first transmission rod 40 is fixedly mounted with a toothed sleeve 41, fixedly mounted on the gear cylinder 36 and pluggable and meshing with the toothed sleeve 41 for transmitting the toothed sleeve block 37, an electric telescopic rod 39 fixedly mounted on the protective shell 63 for regulating the lateral movement of the mounting plate 35 and the gear cylinder 36, the output shaft of the electric telescopic rod 39 is fixedly connected to the mounting plate 35; first pulleys 42 are respectively fixedly mounted on the first transmission rod 40 and the winding disk 10, and the two first pulleys 42 are sleeved with the same first timing belt 43 for transmission.

[0043] In this embodiment, the driving mechanism arranged on the mounting box 18 has a delicate structural design and each component is tightly connected. The protective shell 63 is fixed on the top of the mounting box 18 by welding, which provides reliable protection for the internal motor 32, the speed regulating mechanism 33 and other components, avoids the influence of the external environment, and prolongs the service life of each component. The motor 32 and the speed regulating mechanism 33 are arranged in the protective shell 63, and the input shaft of the speed regulating mechanism 33 is fixedly connected with the output shaft of the motor 32 through a coupling. This connection mode ensures that the power can be stably and efficiently transmitted from the motor 32 to the speed regulating mechanism 33. The second guide rod 38 is fixedly installed in the protective shell 63, and the mounting plate 35 is slidably sleeved on the second guide rod 38, so that the mounting plate 35 can slide flexibly on the second guide rod 38, providing guidance for the lateral movement of the gear cylinder 36. The gear cylinder 36 is rotatably mounted on the mounting plate 35 through a bearing, and the gear rod 34 is arranged in the gear cylinder 36 and is fixedly connected with the input shaft of the speed regulating mechanism 33 through a coupling, so as to realize further transmission of power. The first transmission rod 40 is rotatably mounted in the protective shell 63 through a bearing seat, and the toothed sleeve 41 fixedly mounted at one end thereof can be plugged and meshed with the toothed block 37 fixedly mounted on the gear cylinder 36, thereby realizing the transmission of power from the gear cylinder 36 to the first transmission rod 40. The electric telescopic rod 39 is fixedly mounted on the protective shell 63, and its output shaft is fixedly connected to the mounting plate 35, which can accurately regulate the lateral movement of the mounting plate 35 and the gear cylinder 36. The first pulley 42 is fixedly mounted on the first transmission rod 40 and the winding disk 10, respectively, and is connected by the first timing belt 43 sleeve, thereby realizing the final transmission of power from the first transmission rod 40 to the winding disk 10. Compared with a device without a driving mechanism or a simple driving mechanism, this setting makes the entire driving process more stable and reliable, and the cooperative working ability between the various components is stronger, providing a solid guarantee for the stable operation of the lifting mechanism.

[0044] When the winding reel 10 needs to be driven to rotate, the motor 32 is started, and the power outputted by the motor 32 is transmitted to the speed regulating mechanism 33 through the coupling. The speed regulating mechanism 33 can adjust the power according to actual needs, and the power after speed adjustment is transmitted to the gear cylinder 36 through the gear rod 34, so that the gear cylinder 36 rotates. At this time, if it is necessary to transmit the power to the first transmission rod 40, the electric telescopic rod 39 can be started, and the electric telescopic rod 39 pushes the mounting plate 35 and the gear cylinder 36 to move laterally on the second guide rod 38, so that the tooth groove block 37 on the gear cylinder 36 is plugged and engaged with the tooth groove sleeve 41 on the first transmission rod 40. The rotation of the gear cylinder 36 drives the tooth groove block 37 to rotate, and then drives the first transmission rod 40 to rotate through the tooth groove sleeve 41. When the first transmission rod 40 rotates, the first pulley 42 on it rotates accordingly, and drives the first pulley 42 on the winding reel 10 to rotate through the first timing belt 43, thereby realizing the rotation of the winding reel 10. Compared with the traditional single power transmission method, this driving method can more flexibly control the rotation speed and rotation timing of the winding disk 10, and can accurately adjust the lifting and lowering of the net basket 7 according to the different growth stages and operation requirements of the Coptis chinensis seedlings, thereby improving the adaptability of the device and the accuracy of operation.

[0045] When the operator uses the three-dimensional cultivation device, due to the presence of the driving mechanism, the lifting and lowering of the net basket 7 can be controlled more easily and accurately. The speed regulating mechanism 33 can flexibly adjust the rotation speed of the winding disk 10 to meet the requirements of the lifting and lowering speed of the net basket 7 under different conditions, reduce the error and difficulty of manual operation, and reduce labor intensity. The precise regulation of the gear cylinder 36 and the mounting plate 35 by the electric telescopic rod 39 makes the power transmission process more stable and reliable, avoiding problems such as abnormal lifting and lowering of the net basket 7 due to unstable power transmission. At the same time, the effective protection of the internal components by the protective shell 63 reduces the damage and maintenance frequency of the components and reduces the maintenance cost of the equipment.

[0046] In another embodiment of the present invention, a guiding and crushing mechanism for guiding and crushing fertilizer is provided in the feeding tube 5, and the guiding and crushing mechanism includes: a spiral rod 44 rotatably installed in the feeding tube 5 through a sealed bearing; a grinding block 45 rotatably installed in the feeding tube 5 through a bearing seat, and protrusions 46 for crushing fertilizer particles are staggered and fixedly installed on the grinding block 45 and the inner wall of the feeding tube 5; a fan blade 47 fixed to the bottom of the grinding block 45 through a mounting rod; a collecting bucket 48 fixedly installed on the discharge end of the feeding tube 5, and a conduit 49 is fixedly connected to the collecting bucket 48, and a plurality of through holes are opened on the conduit 49 for passing fertilizer residues; two bevel teeth 55 fixedly installed on the spiral rod 44 and the grinding block 45 respectively and meshing with each other.

[0047] In this embodiment, the guide crushing mechanism provided in the feeding tube 5 has its components reasonably installed and tightly connected. The screw rod 44 is rotatably installed in the feeding tube 5 through a sealed bearing. The sealed bearing ensures the flexibility of the screw rod 44 in rotation, and prevents the fertilizer powder from leaking, thereby ensuring the sealing in the feeding tube 5. The grinding block 45 is rotatably installed in the feeding tube 5 through a bearing seat, and can be flexibly rotated in the feeding tube 5. The protrusions 46 fixedly installed on the inner wall of the grinding block 45 and the feeding tube 5 form an effective crushing structure. The fan blade 47 is fixed to the bottom of the grinding block 45 through a mounting rod, and can rotate with the rotation of the grinding block 45. The collecting bucket 48 is fixedly installed at the discharge end of the feeding tube 5, and is used to collect the crushed fertilizer residue. The conduit 49 is fixedly connected to the collecting bucket 48, and the conduit 49 is provided with a plurality of through holes for the fertilizer residue to pass through, so as to facilitate the discharge of the fertilizer residue. The two bevel teeth 55 respectively fixed on the screw rod 44 and the grinding block 45 mesh with each other, realizing the power transmission between the screw rod 44 and the grinding block 45. Compared with the device without the guide crushing mechanism, the installation and connection of these components can more effectively crush and guide the fertilizer, improve the efficiency and quality of fertilizer addition, and provide better conditions for the subsequent water-fertilizer mixing.

[0048] When it is necessary to add fertilizer to the water tank 4, the fertilizer particles enter from the feed end of the feeding tube 5. The screw rod 44 rotates to guide the fertilizer particles to the discharge end of the feeding tube 5. During the guiding process, the fertilizer particles interact with the grinding block 45 and the protrusions 46 on the inner wall of the feeding tube 5, and the protrusions 46 squeeze and crush the fertilizer particles. At the same time, the grinding block 45 rotates under the power transmitted by the screw rod 44 through the bevel teeth 55, and the protrusions 46 on the grinding block 45 and the protrusions 46 on the inner wall of the feeding tube 5 further interlace and squeeze the fertilizer particles, so that they are crushed into smaller pieces. The fan blades 47 at the bottom of the grinding block 45 rotate with the rotation of the grinding block 45. The rotation of the fan blades 47 can accelerate the movement speed of the fertilizer particles, so that they can better contact with the protrusions 46 and improve the crushing effect. The crushed fertilizer debris enters the collecting bucket 48 through the through hole on the guide tube 49, and then enters the water tank 4 through the subsequent pipeline. Compared with the traditional method of directly adding fertilizer, this guided crushing method can make the fertilizer particles smaller and more uniform, which is conducive to the dissolution and mixing of fertilizer in water, improves the quality of water and fertilizer, and provides more easily absorbed nutrients for Picrorhizoma Cerifera seedlings.

[0049] When the operator uses the stereoscopic cultivation device to add fertilizer, due to the presence of the guide crushing mechanism, the fertilizer can be added to the water tank 4 more easily, and there is no need to worry about the problem that the fertilizer particles are too large to affect the dissolution and mixing, which reduces the troubles in the operation process and reduces the difficulty of operation. At the same time, the guide crushing mechanism can automatically crush and guide the fertilizer, reducing the workload and labor intensity of manually crushing the fertilizer. In addition, the fine fertilizer particles after crushing can be better dissolved in water to form a uniform water-fertilizer solution, providing more balanced nutrients for the picrorhizoma serrata seedlings, which is conducive to improving the survival rate and growth quality of the seedlings. Moreover, the setting of the mechanism further improves the automation of the entire device, reduces the problems such as inaccurate fertilizer addition caused by improper manual operation, improves the practicality and reliability of the device, enhances the advantages of the entire stereoscopic cultivation device in practical applications, and provides strong support for the efficient planting of picrorhizoma serrata.

[0050] In another embodiment of the present invention, a first transmission mechanism for driving the screw rod 44, the grinding block 45 and the rotating rod 26 to rotate is provided in the gear cylinder 36 and the mounting box 18, and the first transmission mechanism includes: a second transmission rod 50 in the mounting box 18 is rotatably mounted through a bearing seat, one end of the second transmission rod 50 is fixedly connected to the screw rod 44 through a coupling; second pulleys 53 are respectively fixedly mounted on the second transmission rod 50 and the rotating rod 26, and a second timing belt 54 for transmission is sleeved on the two second pulleys 53; a first gear 51 and a second gear 52 are respectively fixedly mounted on the second transmission rod 50 and the gear cylinder 36 and can engage and disengage with each other.

[0051] In this embodiment, the first transmission mechanism arranged in the gear cylinder 36 and the installation box 18 has its components installed in an orderly manner and connected firmly. The second transmission rod 50 is rotatably installed in the installation box 18 through the bearing seat, which ensures that the second transmission rod 50 can rotate flexibly and provides a basis for subsequent power transmission. One end of the second transmission rod 50 is fixedly connected to the screw rod 44 through a coupling, and this connection method can stably transmit power from the second transmission rod 50 to the screw rod 44. The second pulley 53, which is respectively fixedly installed on the second transmission rod 50 and the rotating rod 26, realizes the transmission of power between the second transmission rod 50 and the rotating rod 26 through the sleeved second timing belt 54, and the setting of the second timing belt 54 ensures the stability and accuracy of the transmission. The first gear 51 and the second gear 52 are respectively fixedly installed on the second transmission rod 50 and the gear cylinder 36, and the two can mesh and separate with each other. This design allows the transmission of power to be controlled as needed. The installation and connection of the various components of the first transmission mechanism cooperate with other parts in the device. Compared with the case without the transmission mechanism, it can more effectively integrate power resources, provide stable power support for the rotation of the screw rod 44, the grinding block 45 and the rotating rod 26, and further optimize the operating efficiency of the entire device.

[0052] When it is necessary to drive the screw rod 44, the grinding block 45 and the rotating rod 26 to rotate, the power is first transmitted from the gear cylinder 36. When the first gear 51 and the second gear 52 are meshed with each other, the rotation of the gear cylinder 36 drives the first gear 51 to rotate through the second gear 52, thereby rotating the second transmission rod 50. When the second transmission rod 50 rotates, the screw rod 44 is driven to rotate through the coupling to achieve the guiding and preliminary crushing of the fertilizer. At the same time, when the second transmission rod 50 rotates, the second pulley 53 on it rotates accordingly, and the second pulley 53 on the rotating rod 26 is driven to rotate through the second timing belt 54, so that the rotating rod 26 rotates, and the stirring blade 27 is driven to stir the water fertilizer in the water tank 4. The grinding block 45 and the screw rod 44 are meshed with each other through the bevel teeth 55. When the screw rod 44 rotates, it will drive the grinding block 45 to rotate. The protrusion 46 on the grinding block 45 interacts with the protrusion 46 on the inner wall of the feeding pipe 5 to further squeeze and crush the fertilizer. Compared with the decentralized power drive mode, this transmission mode can distribute power more reasonably, coordinate work according to the working requirements of different components, improve the overall operating efficiency of the device, and ensure that operations such as fertilizer crushing, conveying, and water-fertilizer mixing can be carried out in an orderly manner.

[0053] When the operator uses the three-dimensional cultivation device, due to the existence of the first transmission mechanism, there is no need to separately control the power of the spiral rod 44, the grinding block 45 and the rotating rod 26, which reduces the complexity of the operation, the difficulty of operation and the labor intensity. The first transmission mechanism can flexibly control the transmission and distribution of power according to actual needs, avoiding the problems such as abnormal operation of components caused by uneven power distribution. At the same time, the setting of the mechanism further improves the automation level of the entire device, reduces manual intervention, and improves the accuracy and reliability of the operation. Through the coordinated work of the first transmission mechanism, the fertilizer can be more fully crushed and guided, and the water and fertilizer can be mixed more evenly, providing a better growth environment for the picrorhizoma serrata seedlings, which is conducive to improving the survival rate and growth quality of the seedlings, enhancing the competitiveness of the entire three-dimensional cultivation device in practical applications, and providing a more powerful technical guarantee for the efficient planting of picrorhizoma serrata.

[0054] In another embodiment of the present invention, a second transmission mechanism for driving the rotating shaft 20 to rotate is provided in the installation box 18, and the second transmission mechanism includes: a third transmission rod 56 rotatably installed in the installation box 18 through a bearing seat, and the third transmission rod 56 and the rotating shaft 20 are both provided with a third pulley 57, and the third pulley 57 is provided with a third timing belt 58 for transmission; a third gear 59 fixedly installed on the third transmission rod 56 and capable of engaging and disengaging with the second gear 52.

[0055] In this embodiment, the second transmission mechanism arranged in the installation box 18 has its components installed reasonably and connected tightly. The third transmission rod 56 is rotatably installed in the installation box 18 through the bearing seat, which provides a guarantee for the flexible rotation of the third transmission rod 56, so that it can be used as a key component for power transmission. The third transmission rod 56 and the rotating shaft 20 are both sleeved with a third pulley 57, and the two third pulleys 57 are connected by the sleeved third timing belt 58. This connection method can stably and accurately transmit power from the third transmission rod 56 to the rotating shaft 20, ensuring the stability and synchronization of the transmission. The third gear 59 is fixedly installed on the third transmission rod 56, and can be meshed and separated with the second gear 52. This design allows the transmission of power to be controlled and switched according to actual needs. The installation and connection of the various components of the second transmission mechanism cooperate with the first transmission mechanism and other parts in the device. Compared with the case without the transmission mechanism, it can more effectively integrate power resources, provide stable power support for the rotation of the rotating shaft 20, further improve the power transmission system of the entire device, and improve the operation efficiency of the device.

[0056] When the rotating shaft 20 needs to be driven to rotate, the power transmission path is as follows: when the third gear 59 and the second gear 52 are meshed with each other, the rotation of the gear cylinder 36 will drive the third gear 59 to rotate through the second gear 52, thereby rotating the third transmission rod 56. When the third transmission rod 56 rotates, the third pulley 57 thereon rotates accordingly, and the third pulley 57 on the rotating shaft 20 is driven to rotate through the third timing belt 58, thereby realizing the rotation of the rotating shaft 20. The rotation of the rotating shaft 20 will drive the impeller 21 to rotate, and then the water in the water tank 4 is pumped into the water guide shell 19 through the water pumping pipe 24, and the water is evenly transported to each cultivation trough 2 through the water outlet pipe 22 and the diversion pipe 23. Compared with the method of setting a power source for the rotating shaft 20 alone, this transmission method can more reasonably utilize the existing power resources of the device, and through the coordinated work with the first transmission mechanism, according to different work requirements, flexibly control the transmission of power, ensure that operations such as watering in the device can be carried out in an orderly manner, and improve the overall operation efficiency of the device.

[0057] When the operator uses the stereoscopic cultivation device, due to the existence of the second transmission mechanism, there is no need to set a complex power control device for the rotating shaft 20 separately, which reduces the complexity of operation, the difficulty of operation and the labor intensity. The second transmission mechanism can flexibly control the transmission and distribution of power according to actual needs, avoiding problems such as component operation failure caused by improper power distribution. At the same time, the coordinated work of this mechanism and the first transmission mechanism further improves the degree of automation of the entire device, reduces the frequency of manual intervention, and improves the accuracy and reliability of operation. Through the stable operation of the second transmission mechanism, the rotation of the rotating shaft 20 can be guaranteed, thereby ensuring the normal operation of the irrigation system, providing a suitable water supply for the picrorhizoma serrata seedlings, which is conducive to improving the survival rate and growth quality of the seedlings, enhancing the performance and competitiveness of the entire stereoscopic cultivation device in practical applications, and providing more comprehensive technical support for the efficient planting of picrorhizoma serrata.
