Description

Technical Field

[0001] This utility model belongs to the field of three-dimensional cultivation technology of Chinese medicinal materials, specifically relating to a three-dimensional cultivation device for Chinese medicinal materials under forest cover. Background Technology

[0002] In the large-scale cultivation of medicinal herbs under forest cover, water management is a key factor determining the quality and yield of the herbs. This is especially true for precious herbs such as ginseng, Panax notoginseng, and Polygonatum sibiricum, whose water requirements vary significantly at different growth stages. However, the widely used forest irrigation systems generally suffer from inaccurate quantitative control, relying on manual experience or simple timers for irrigation. This not only fails to meet the differentiated water requirements at different growth stages but also easily leads to root rot or soil nutrient loss due to over-irrigation. In particular, in forest environments with complex terrain and uneven sunlight, traditional irrigation methods struggle to achieve precise water supply to each individual plant, resulting in inconsistent growth of plants in different locations within the same planting area. This severely affects the consistency of the quality of medicinal herbs and the profitability of cultivation.

[0003] In the multi-layered spatial distribution of forest understory vertical cultivation systems, the uniform distribution and precise control of water flow face enormous challenges, especially for medicinal materials with special growth substrates such as Ganoderma lucidum and Dendrobium. Traditional irrigation equipment mostly adopts a fixed flow design, which cannot be adjusted according to the differentiated needs of different layers and different medicinal material varieties. This may result in plants receiving excessive water while lower-layer plants receive insufficient water, or physical damage to tender plants and growth substrate caused by excessive water flow impact.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a three-dimensional cultivation device for Chinese medicinal herbs under forest cover, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A three-dimensional cultivation device for medicinal herbs under forest cover includes:

[0008] A support frame, on which a cultivation mechanism is provided;

[0009] The cultivation mechanism includes a water tank, a water pump, an output pipe, a branch pipe, a spray pipe, and nozzles. The water tank is located at the bottom of the support frame, the water pump is connected to the top surface of the water tank, the output pipe is connected to the output end of the water pump, the branch pipe is located at the top of the output pipe, multiple sets of spray pipes are installed inside the support frame and connected to the branch pipes respectively, and multiple sets of nozzles are distributed on the bottom surface of the multiple sets of spray pipes. A flow control mechanism is provided between the output pipe and the branch pipe.

[0010] The flow control mechanism includes a connecting sleeve, an adjusting sleeve, a screw, a transmission sleeve, a control sleeve, a connecting frame, sealing rods, and flow passage holes. The connecting sleeve is fixed to the bottom end of the diverter pipe. The adjusting sleeve is rotatably connected to the output pipe. The screw is fixed inside the adjusting sleeve. The transmission sleeve is threaded to the outer wall of the screw. The control sleeve is fixed to the outer wall of the transmission sleeve. The connecting frame is fixed inside the connecting sleeve and rotatably connected to the screw. Multiple sets of sealing rods are fixed to the outer wall of the connecting frame. Multiple sets of flow passage holes are distributed inside the control sleeve and are slidably connected to multiple sets of sealing rods.

[0011] Furthermore, the support frame is fixedly equipped with a tray, and the tray is provided in multiple sets, with cultivation boxes installed on the top surface of each tray. The cultivation boxes are provided in multiple sets. This design forms a multi-layer three-dimensional cultivation structure, which makes full use of the vertical space under the forest, increases the planting quantity per unit area, and facilitates the layered management of Chinese medicinal materials with different growth needs, thereby improving cultivation efficiency and space utilization.

[0012] Furthermore, the inner wall of the connecting sleeve is fixedly provided with guide strips. Multiple sets of guide strips are provided and all are slidably connected to the control sleeve. This structure ensures that the control sleeve moves smoothly along the axial direction without rotation during the adjustment process, ensuring the precise alignment of the sealing rod and the flow hole, improving the accuracy and stability of flow regulation, and avoiding uneven water flow caused by the misalignment of the control sleeve.

[0013] Furthermore, the lengths of the multiple sets of sealing rods are all set to be different. This differentiated design allows the flow area to be gradually changed in a preset order when rotating the adjustment sleeve, realizing fine-grained step adjustment of water flow, meeting the different water requirements of different Chinese medicinal materials at different growth stages, and improving irrigation accuracy.

[0014] Furthermore, the top of the sealing rod and the outer side of the flow passage are all provided with rounded corners. This rounded corner design reduces the resistance and turbulence when water flows through, making the water flow more stable and smooth, reducing the water pump load and energy consumption, while reducing the wear between the sealing rod and the flow passage, and extending the service life of the flow control mechanism.

[0015] Furthermore, a positioning mechanism is provided on the outer side of the adjusting sleeve. The positioning mechanism includes an installation ring, a positioning block, a fixing ring, a slide bar, a clamping block, a tension spring, and a positioning groove. The installation ring is fixed to the outer wall of the adjusting sleeve. Multiple sets of positioning blocks are distributed on the outer wall of the installation ring. The fixing ring is fixed to the outer wall of the connecting sleeve. Multiple sets of slide bars are distributed on the outer wall of the fixing ring. Multiple sets of clamping blocks slide on the outer walls of the multiple sets of slide bars respectively. Multiple sets of tension springs are provided and connected between the multiple sets of clamping blocks respectively. The positioning grooves are respectively located on the top of the multiple sets of clamping blocks. This combined mechanism realizes accurate locking of the position of the adjusting sleeve, prevents positional shift after equipment vibration or long-term use, ensures the stability and repeatability of irrigation water volume, and facilitates operators to quickly select the irrigation intensity suitable for different Chinese medicinal materials.

[0016] Furthermore, baffles are fixedly provided on the outer walls of the multiple sets of slide bars, and the outer walls of the multiple sets of baffles abut against the inner sides of the multiple sets of clamping blocks. This design limits the excessive sliding of the clamping blocks, prevents the tension spring from being overstretched or deformed, ensures the reliable operation of the positioning mechanism, simplifies the clamping block reset process, and improves the response speed and service life of the positioning mechanism.

[0017] Furthermore, all of the aforementioned positioning blocks and positioning slots are designed in an arc shape. This arc shape design increases the contact area, improves positioning accuracy and stability, and facilitates the positioning blocks to slide into the positioning slots to achieve automatic centering, reducing the difficulty of operation. The arc transition also reduces stress concentration, extends the service life of components, and improves the overall reliability of the device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The cultivation mechanism of this utility model adopts a combination design of water tank, water pump, output pipe, diversion pipe, spray pipe and nozzle, which solves the problem of irrigation of Chinese medicinal materials under forest mentioned in the background technology. The mechanism draws water from the water tank and delivers it to the diversion pipe through the water pump, and then distributes it evenly to the cultivation boxes of different levels through multiple sets of spray pipes and nozzles to form a three-dimensional irrigation system. The multiple sets of trays and cultivation boxes set in the support frame constitute a complete three-dimensional cultivation structure, making full use of the space resources under the forest. This design not only realizes the synchronous irrigation of Chinese medicinal materials of different levels, but also ensures the uniform distribution of water by reasonably arranging the nozzle positions, effectively solving the problem of uneven water management in traditional forest cultivation. It is particularly suitable for the refined cultivation needs of precious medicinal materials such as ginseng and Panax notoginseng, and provides technical guarantee for improving the consistency of medicinal material quality.

[0020] (2) The flow control mechanism of this utility model consists of a connecting sleeve, an adjusting sleeve, a screw, a transmission sleeve, a control sleeve, a connecting frame, a sealing rod, and a flow passage hole. It cleverly solves the problem of water flow rate and velocity regulation mentioned in the background technology. The mechanism drives the screw and transmission sleeve to engage by rotating the adjusting sleeve, and the control sleeve slides along the guide strip to change the number of sealing holes and sealing rods, thereby accurately regulating the water flow area. The design of multiple sealing rods of different lengths allows the flow area to be gradually changed when rotating the adjusting sleeve, realizing the gradual regulation of water flow. The rounded corner design of the top of the sealing rod and the outside of the flow passage hole reduces water flow resistance and turbulence. This innovative structure can not only accurately control the irrigation water volume for Chinese medicinal materials at different growth stages, but also adjust the water flow speed according to the needs of different levels of cultivation boxes, avoid water flow impact on young medicinal materials, and solve the problem of excessive moisture in rainy weather. It effectively prevents the occurrence of diseases and pests of medicinal materials and the loss of effective ingredients, and significantly improves the cultivation quality and economic benefits of Chinese medicinal materials under forest.

[0021] (3) The positioning mechanism of this utility model includes an installation ring, a positioning block, a fixing ring, a slide bar, a clamping block, a tension spring, and a positioning groove, which provides a precise position locking function for the flow control mechanism. The installation ring is fixed on the outer wall of the adjusting sleeve to form a rotation base. The arc-shaped positioning block and positioning groove design enhance the positioning accuracy and stability. The combination of the fixing ring and the slide bar ensures that the sliding trajectory of the clamping block is precise and controllable. The mechanism achieves accurate locking of the position of the adjusting sleeve through the precise cooperation of the positioning block and the positioning groove. The tension spring provides the clamping block with a return force, ensuring that the positioning process is completed automatically. The baffle design prevents the clamping block from sliding excessively. This gear-type positioning design not only enables operators to quickly select the appropriate irrigation intensity according to the water requirements of different Chinese medicinal materials, but also ensures that the flow rate setting can be maintained even after equipment vibration or long-term use. It provides a reliable guarantee for the scientific and standardized cultivation of Chinese medicinal materials under forests. It is especially suitable for the cultivation of precious medicinal materials that require fine water management, and effectively improves the practicality and reliability of the three-dimensional cultivation system.

[0029] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0030] See appendix Figure 1-5 A three-dimensional cultivation device for medicinal herbs under forest cover includes a support frame 1, on which a cultivation mechanism is mounted. The cultivation mechanism includes a water tank 2, a water pump 3, an output pipe 4, a diversion pipe 5, a spray pipe 6, and nozzles 7. The water tank 2 is located at the bottom of the support frame 1, the water pump 3 is connected to the top surface of the water tank, the output pipe 4 is connected to the output end of the water pump 3, the diversion pipe 5 is located at the top of the output pipe 4, multiple sets of spray pipes 6 are installed inside the support frame 1 and connected to the diversion pipes 5 respectively, and multiple sets of nozzles 7 are distributed on the bottom surface of the multiple sets of spray pipes 6. A flow control mechanism is provided between the output pipe 4 and the diversion pipe 5, and the flow control mechanism includes a connecting sleeve. 8. Adjusting sleeve 9, screw 10, transmission sleeve 11, control sleeve 12, connecting frame 13, sealing rod 14, and flow passage hole 15. The connecting sleeve 8 is fixed to the bottom end of the diverter pipe 5. The adjusting sleeve 9 is rotatably connected to the output pipe 4 and the adjusting sleeve 9. The screw 10 is fixed inside the adjusting sleeve 9. The transmission sleeve 11 is threaded to the outer wall of the screw 10. The control sleeve 12 is fixed to the outer wall of the transmission sleeve 11. The connecting frame 13 is fixed inside the connecting sleeve 8 and rotatably connected to the screw 10. Multiple sets of sealing rods 14 are fixed to the outer wall of the connecting frame 13. Multiple sets of flow passage holes 15 are distributed inside the control sleeve 12 and are slidably connected to multiple sets of sealing rods 14.

[0031] The support frame 1 is fixedly provided with a tray 16. There are multiple sets of trays 16 and cultivation boxes 17 are installed on the top surface of each tray 16. There are multiple sets of cultivation boxes 17. By setting multiple sets of trays 16 vertically inside the support frame 1, a three-dimensional planting structure is formed. Multiple sets of cultivation boxes 17 are installed on each tray 16, so as to maximize the utilization of space resources and increase the planting density per unit area.

[0032] The inner wall of the connecting sleeve 8 is fixedly provided with guide strips 18. Multiple sets of guide strips 18 are provided and are all slidably connected to the control sleeve 12. The multiple sets of guide strips 18 are distributed in a ring on the inner wall of the connecting sleeve 8, forming a sliding fit with the control sleeve 12, restricting the control sleeve 12 to only move axially and not rotate, ensuring that the control sleeve 12 maintains precise alignment with the sealing rod 14 during the adjustment process.

[0033] The lengths of the multiple sealing rods 14 are all set to be different, so that the control sleeve 12 can gradually change the blocking state with the flow hole 15 in a predetermined sequence during axial movement, thereby realizing a precise step-like change in the water flow area and thus finely controlling the water flow rate.

[0034] The tops of the multiple sealing rods 14 and the outer sides of the flow holes 15 are all rounded to reduce the local resistance coefficient and turbulence when water flows through, making the water flow smoother. At the same time, it reduces the contact stress between the sealing rods 14 and the flow holes 15, reduces wear, and extends the service life of the components.

[0035] In this embodiment, Chinese medicinal herbs are planted in multiple cultivation boxes 17. Water is pumped from the water tank 2 by the water pump 3 and transported to the diversion pipe 5 through the delivery pipe. After being transported to multiple spray pipes 6 through the diversion pipe 5, the water is sprayed into the cultivation boxes 17 through multiple nozzles 7 for watering. When it is necessary to adjust the flow rate and velocity of the water, the rotating adjustment sleeve 9 drives the screw 10 to engage with the transmission sleeve 11 through the thread. This causes the transmission sleeve 11 to drive the control sleeve 12 to slide along multiple guide bars 18, thereby changing the number of blockages in the multiple flow holes 15 and the multiple sealing rods 14, thus adjusting the flow area of ​​the water and regulating the flow rate and velocity of the water.

[0036] In this embodiment, a positioning mechanism is provided on the outer side of the adjusting sleeve 9. The positioning mechanism includes a mounting ring 19, a positioning block 20, a fixing ring 21, a slide bar 22, a clamping block 23, a tension spring 24, and a positioning groove 25. The mounting ring 19 is fixed to the outer wall of the adjusting sleeve 9. Multiple sets of positioning blocks 20 are distributed on the outer wall of the mounting ring 19. The fixing ring 21 is fixed to the outer wall of the connecting sleeve 8. Multiple sets of slide bars 22 are distributed on the outer wall of the fixing ring 21. Multiple sets of clamping blocks 23 slide on the outer walls of the multiple sets of slide bars 22. Multiple sets of tension springs 24 are provided and connected between the multiple sets of clamping blocks 23. The positioning grooves 25 are respectively provided at the top of the multiple sets of clamping blocks 23. Each set of slide bars 22 has a baffle 26 fixedly provided on its outer wall, and the outer walls of the multiple sets of baffles 26 abut against the inner side of the multiple sets of clamping blocks 23. The multiple sets of positioning blocks 20 and positioning grooves 25 are all arc-shaped.

[0037] As the adjusting sleeve 9 rotates, it drives the mounting ring 19 and multiple sets of positioning blocks 20 to rotate. Through the arc-shaped design of the multiple sets of positioning blocks 20 and the positioning groove 25, the multiple sets of positioning blocks 20 disengage from the positioning groove 25 and push the clamping block 23 to slide along the slide bar 22. The movement of the multiple sets of clamping blocks 23 stretches the tension spring 24. After disengaging from the positioning groove 25, the multiple sets of positioning blocks 20 will move into the next set of positioning grooves 25. At this time, the tension spring 24 contracts and pulls the clamping block 23 to slide along the slide bar 22 and abut against one side of the baffle 26. At this time, the positioning groove 25 abuts against the outer wall of the positioning block 20. When the adjusting sleeve 9 stops rotating, the multiple sets of clamping blocks 23 hold the positioning block 20 to position the adjusting sleeve 9. When the adjusting sleeve 9 rotates, it forms a gear rotation.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
