Description

Technical Field

[0001] This utility model relates to the field of agricultural and forestry equipment technology, and more specifically, to a non-destructive single-plant seed collection device for rare and endangered herbaceous plants. Background Technology

[0002] In biodiversity conservation activities, the collection of germplasm from rare and endangered plants is a crucial step, as artificial seed collection and cultivation can expand the populations of these species. However, for rare herbaceous plants growing in unique environments such as hillsides, their seeds are easily detached after maturation due to natural factors like rainfall and wind, scattering into thick layers of dead leaves, making collection extremely difficult and resulting in significant losses of germplasm resources. Furthermore, these herbaceous plants and their seedlings are quite fragile, requiring care to avoid mechanical damage to the parent plant to prevent impacting their subsequent growth and reproduction.

[0003] Existing methods for collecting seeds in the wild mostly involve manual picking or using scissors to cut the seed spikes. These active methods are inefficient and struggle to effectively collect naturally matured seeds. Furthermore, the picking process can damage herbaceous plants by touching or pulling them. In addition, some passive collection devices exist, using fixed bases or collection nets to collect seeds. While these devices can catch naturally fallen seeds, they lack effective in-situ protection, leading to seed loss. Moreover, the devices themselves are susceptible to the effects of mountainous terrain and wind, resulting in insufficient stability.

[0004] Therefore, it is necessary to provide a device to overcome the above problems. Utility Model Content

[0005] The main purpose of this invention is to provide a non-destructive single-plant seed collection device for rare and endangered herbaceous plants, so as to at least solve the problems of existing seed collection devices being unable to collect seeds non-destructively and the collected seeds being easily lost.

[0006] To achieve the above objectives, this utility model provides a non-destructive single-plant seed collection device for rare and endangered herbaceous plants, comprising: a frame disposed below the plant; a linkage mechanism on the frame, the linkage mechanism being used to follow the shape of the plant's main stem; multiple fixing mechanisms disposed on the linkage mechanism to fix the main stem to the linkage mechanism; a collection mechanism disposed on the frame to collect the seeds; and a monitoring mechanism disposed inside the frame to monitor the status of the collected seeds.

[0010] Furthermore, a first magnet is provided on the connector base, and a second magnet is provided on the connector block. The connector block is attracted to the connector base by the magnetic force of the first magnet and the second magnet.

[0011] Furthermore, the collecting mechanism includes: a first vibration motor mounted on a linkage mechanism to accelerate the falling of mature seeds through vibration; a collecting net disposed on a frame and below the plant to passively receive the seeds falling from the plant; a guide net disposed within the frame and below the collecting net to guide the seeds collected by the collecting net to fall; a filter net disposed within the frame and below the guide net to receive the seeds falling from the guide net and filter them out; and a second vibration motor disposed on the filter net to cause the filter net to vibrate.

[0014] Furthermore, the monitoring mechanism also includes: a camera mounted on the collection box to monitor the state of the seeds inside the collection box; and a battery mounted on the carrier box to power the weighing sensor and the camera.

[0015] Furthermore, the seed collecting device also includes a positioning mechanism, which is located at the bottom of the frame and penetrates the soil, and is used to fix the frame in the soil.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 As shown, this utility model discloses a non-destructive single-plant seed collection device for rare and endangered herbaceous plants, comprising: a frame 10, a linkage mechanism 20, multiple fixing mechanisms 30, a collection mechanism 40, and a monitoring mechanism 50. The frame 10 is positioned below the plant; the linkage mechanism 20 is on the frame 10 and follows the shape of the plant's main stem; the multiple fixing mechanisms 30 are mounted on the linkage mechanism 20 to fix the main stem to it; the collection mechanism 40 is mounted on the frame 10 to collect seeds; and the monitoring mechanism 50 is located inside the frame 10 to monitor the state of the collected seeds. The collection mechanism 40 collects seeds into the frame 10 without damage, preventing rainwater from mixing with the seeds and entering the monitoring mechanism 50. The frame 10 provides in-situ protection for the seeds, preventing seed loss. This solves the problems of existing seed collection devices being unable to collect seeds non-destructively and the easy loss of collected seeds.

[0021] Furthermore, such as Figure 1 As shown, the frame 10 includes a housing 11 and a cover plate 12. The cover plate 12 is mounted on the housing 11. The housing 11 is positioned on one side below the plant from which seeds are to be collected and close to the plant, so that naturally fallen seeds can smoothly enter the collection mechanism 40. The inner wall of the housing 11 has steps for mounting the collection mechanism 40. The top of the housing 11 has threaded holes, and the cover plate 12 can be fixed to the housing 11 with bolts. A first through hole is provided on the top of the cover plate 12, allowing fallen seeds to enter the interior of the housing 11. After installation, the cover plate 12, together with the housing 11, forms a stable shell, ensuring that the linkage mechanism 20 and the collection mechanism 40 are not disturbed by external forces.

[0022] Furthermore, such as Figure 2As shown, the linkage mechanism 20 includes multiple ball hinges 22 and multiple links 21. The multiple links 21 and multiple ball hinges 22 are alternately connected in series to form a multi-stage chain-like hinge structure to follow the shape of the main stem. Each link 21, as a rigid structure, provides the necessary shape-maintaining function. Adjacent links 21 are connected by ball hinges 22, which allow large-angle, multi-degree-of-freedom rotation. The ball hinges 22 are high-damping ball hinges, which can be manually adjusted to the required angle and shape to adapt to the natural curvature of the plant's main stem and follow its extension. Simultaneously, the multi-stage chain-like hinge structure formed by the ball hinges 22 and links 21 can withstand the lateral pressure of the plant, maintaining its shape even under conditions such as wind and rain in natural environments. The length of the linkage mechanism 20 can be changed by adding or removing links 21 and ball hinges 22. The ball hinge 22 is installed at the lowermost end of the linkage mechanism 20 in space and is fixed to the cover plate 12 with bolts. In this embodiment, three ball joints 22 and three connecting rods 21 are used.

[0023] Furthermore, such as Figure 2As shown, the fixing mechanism 30 includes: a hollow stud 31, a connecting seat 32, a nut 33, a connecting block 34, and a fixing ring 35. The hollow stud 31 is sleeved on the connecting rod 21; the connecting seat 32 is sleeved on the hollow stud 31; the connecting block 34 is disposed on the connecting seat 32; the fixing ring 35 is sleeved on the main stem and passes through the connecting block 34 to fix the main stem to the connecting rod mechanism 20 through the connecting block 34, the connecting seat 32, and the hollow stud 31. The hollow stud 31 serves as a basic sleeve sleeved on the connecting rod 21, and the connecting seat 32 is sleeved on the hollow stud 31 and connected to the hollow stud 31 by threads. The connecting seat 32 can be adjusted along its axial direction and is finally fixed by the nut 33 sleeved on the hollow stud 31. Two nuts 33 can be set on the same side to fix the connecting seat 32 and prevent the connecting seat 32 from loosening. A detachable connecting block 34 is provided on the connecting seat 32. The fixing ring 35 is made of an elastomer or has a structure with a soft inner lining, which wraps around the main stem of the plant. The fixing ring 35 is first fitted onto the main stem, and then passed through the connecting block 34. Thus, the main stem is fixed to the hollow stud 31 step by step through the fixing ring 35, the connecting block 34, the connecting seat 32, and finally fixed to the linkage mechanism 20. Specifically, the fixing ring 35 has a third through hole in the middle and a third notch in the circumferential direction that communicates with the third through hole. The main stem can enter the third through hole of the fixing ring 35 radially through the third notch, without having to enter the third through hole axially through the fixing ring 35. Similarly, the connecting seat 32 has a second through hole in the middle and a second notch communicating with the second through hole in the circumferential direction. The main stem can enter the second through hole of the connecting seat 32 radially through the second notch, without having to enter the second through hole axially. When the main stem enters both the third and second through holes simultaneously, the connecting block 34 and the fixing ring 35 are rotated, causing the third and second notches to be misaligned. At the same time, the fixing ring 35 is inserted into the connecting block 34, preventing the main stem from detaching from the fixing mechanism 30 through the third and second notches. The axial height adjustment feature of the connecting seat 32 can adapt to different fixing positions on different main stems. The fixing mechanism 30 and the linkage mechanism 20 can adapt to the shape of the plant and stably fix the plant on the frame 10.

[0024] Furthermore, such as Figure 2As shown, a first magnet 321 is provided on the connecting seat 32, and a second magnet 341 is provided on the connecting block 34. The connecting block 34 is attracted to the connecting seat 32 by the magnetic force of the first magnet 321 and the second magnet 341. The first magnet 321 and the second magnet 341 can be fixed to the connecting seat 32 and the connecting block 34 respectively with glue. During the process of fixing the main stem of the plant to the linkage mechanism 20, the second magnet 341 can fix the connecting block 34 to the connecting seat 32 by self-positioning. During disassembly, the attraction can be released simply by moving along the separation direction. This magnetic attraction structure has a certain displacement capability under the action of sudden external force, such as strong wind, which can not only maintain reliable fixation in the attraction state, but also reduce the constraint stiffness on the main stem under overload conditions, and release the attraction on its own to avoid damage to the main stem.

[0025] Furthermore, such as Figure 2 , Figure 3 and Figure 5As shown, the collecting mechanism 40 includes: a first vibration motor 41, a collecting net 42, a guide net 43, a filter net 44, and a second vibration motor 45. The first vibration motor 41 is mounted on the linkage mechanism 20 to accelerate the falling of mature seeds through vibration; the collecting net 42 is disposed on the frame 10 and below the plant to passively receive the seeds falling from the plant; the guide net 43 is disposed within the frame 10 and below the collecting net 42 to guide the seeds collected by the collecting net 42 to fall; the filter net 44 is disposed within the frame 10 and below the guide net 43 to receive the seeds falling from the guide net 43 and filter them out; the second vibration motor 45 is disposed on the filter net 44 to cause the filter net 44 to vibrate. The first vibration motor 41 can be disposed at any position on the linkage mechanism 20. In this embodiment, it is disposed at the top of the linkage mechanism 20. The first vibration motor 41 can operate under a preset low amplitude condition, applying slight vibration to the adjacent main stem area through the linkage mechanism 20 to promote the natural falling of mature but not yet fallen seeds rather than forced peeling. The collecting net 42 has a large surface area to passively collect falling seeds. It has a truncated cone-shaped structure and is inverted on the cover plate 12. Seeds entering the collecting net 42 gather towards the center and eventually enter the frame 10 through the first through-hole. They then sequentially enter the guide net 43 and the filter net 44, and finally the monitoring mechanism 50. The guide net 43 and filter net 44 are arranged vertically from top to bottom inside the frame 10. The guide net 43 and filter net 44 are fixed inside the housing 11 by a horizontal stepped structure. A 3mm lateral gap is reserved during the fixing of the filter net 44, allowing it some lateral space during the vibration driven by the second vibration motor 45. The guide net 43 is an axisymmetric cylindrical structure that extends along the height direction. A throat is set in the middle along the height direction, with a minimum diameter. The diameter increases from the throat to the upper and lower ends. The whole structure can be equivalent to two funnels connected at the bottom of the funnels. The internal channel formed by this structure resembles an hourglass-shaped channel. Seeds falling from the collecting net 42 converge towards the center as they pass through the guiding net 43. The collecting net 42 has densely packed round holes and a mesh structure, which prevents rainwater from converging towards the center. The middle channel of the guiding net 43 is axially offset from the first through hole. The guiding net can be considered as an upper funnel structure and a lower funnel structure with the throat as the boundary. The surface of the upper funnel structure is mesh-like to prevent rainwater entering from the first through hole from entering the middle channel through the upper funnel structure. The surface of the lower funnel structure is smooth. When a small amount of rainwater enters from the first through hole passes through the upper funnel structure, it flows vertically out of the outer side of the upper funnel structure from the mesh structure and then falls on the smooth outer surface of the lower funnel structure. The side wall of the box 11 is provided with multiple water guiding holes, and the rainwater is then guided and flows out of the outside of the box 11 through the water guiding holes.After passing through the guide net 43, the seeds enter the filter net 44. The filter net 44 uses a second vibration motor 45 to separate large impurities such as fallen leaves and dead branches from the seeds through vibration. The mesh size of the filter net 44 is matched to the particle size of the seeds to be collected, allowing only seeds to pass through while blocking impurities such as fallen leaves and dead branches. The seeds that pass through the filter net 44 finally enter the monitoring mechanism 50.

[0026] Furthermore, such as Figure 3 and Figure 5 As shown, the collecting net 42 includes a collecting net cover 423, a limiting plate 421, and a fixing plate 422. The collecting net cover 423 is disposed on the frame 10 and below the plant from which seeds are to be collected to passively receive seeds falling from the plant. The collecting net cover 423 has a first notch extending from the center outwards. The limiting plate 421 is disposed at the edge of the first notch and extends vertically to limit the seeds on the collecting net cover 423. The fixing plate 422 is disposed on the collecting net cover 423 to fix the collecting net cover 423 to the frame 10. The collecting net cover 423 has a square first notch extending from the center outwards. The function of the first notch is to allow the main stem of the plant extending vertically to pass through the first notch and approach the middle part of the collecting net cover 423, so that the rigid structure of the collecting net cover can be evenly distributed radially along the main stem of the plant, and can reliably passively receive the seeds falling from the plant. Meanwhile, a limiting plate 421 extending vertically is provided at the edge of the first notch to prevent seeds that have entered the collecting mesh cover 423 from leaking out through the first notch. A fixing plate 422 is welded to the collecting mesh cover 423 and can be bolted to the cover plate 12. The function of the fixing plate 422 is to fix the collecting mesh cover 423 to the cover plate 12. Through the collection mechanism 40, seeds can be collected inside the box 11, and rainwater can be prevented from entering the box 11. The linkage mechanism 20 passes through the center of the collecting mesh cover 423 and is mounted on the cover plate 12.

[0027] Furthermore, such as Figure 3 and Figure 5As shown, the monitoring mechanism 50 includes: a carrier box 51, a weighing sensor 55, and a collection box 53. The carrier box 51 is slidably mounted within the frame 10; the weighing sensor 55 is fixedly mounted on the carrier box 51; the collection box 53 is fixedly mounted on the weighing sensor 55 to receive seeds falling from the collection mechanism 40, and the weighing sensor 55 is used to measure the weight of the seeds in the collection box 53. The carrier box 51 has the same function and structure as a drawer, and can be pulled out horizontally from the housing 11 for manual periodic emptying or verification of the seeds in the collection box 53. The collection box 53 is located in the space below the filter screen 44 and is fixed to the carrier box 51 by the weighing sensor 55. The weighing sensor 55 can measure the seeds carried in the collection box 53 in real time. The weighing sensor 55 can be calibrated when the box is empty, and the seed maturation and falling process can be traced by monitoring the seed quality. The seeds are collected in the collection box 53 inside the frame 10 and are protected by the frame 10 from being soaked by rain or disturbed by wind. The frame 10 provides in-situ protection for the seeds.

[0028] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, the monitoring mechanism 50 also includes a camera 56, a battery 52, and a circuit board 54. The camera 56 is mounted on the collection box 53 to monitor the state of the seeds inside; the battery 52 is mounted on the carrier box 51 to power the weighing sensor 55 and the camera 56. The camera 56 is aimed at the inner cavity of the collection box 53, allowing for periodic or real-time visual monitoring of the seeds' appearance. The battery 52 can be a lithium battery to power the camera 56, circuit board 54, and weighing sensor 55. The circuit board 54 specifically controls the camera 56 and the weighing process. The circuit board 54 is equipped with a wireless communication module and a control module, allowing personnel to obtain real-time images and weight information of the seeds inside the collection box 53 via the wireless communication module.

[0029] Furthermore, such as Figure 1 As shown, the seed collection device also includes a positioning mechanism 60. The positioning mechanism 60 is located at the bottom of the frame 10 and penetrates the soil, serving to fix the frame 10 in the soil. The positioning mechanism 60 can employ four sets of vertically extending long rods made of metal. Each long rod has two shaft diameters, with the diameter closer to the housing 11 being larger than the diameter further away. By inserting the four sets of long rods into the soil, the frame 10 can be stably fixed in the soil, ensuring that the frame 10, linkage mechanism 20, fixing mechanism 30, collection mechanism 40, and monitoring mechanism 50 do not shift in position under wind or small animal disturbances.

[0030] In practice, the linkage mechanism 20 is manually adjusted to follow the shape of the plant's main stem. Multiple fixing mechanisms 30 secure the plant's main stem to the linkage mechanism 20. Specifically, fixing rings 35 and connecting blocks 34 are first installed on the plant's main stem, and then the connecting blocks 34 are installed on the connecting seat 32. The vibration of the first vibration motor 41 promotes the falling of mature but not yet detached seeds from the plant. The falling seeds pass sequentially through a collection net 42, a guide net 43, and a filter net 44. The second vibration motor 45 applies vibration to the seeds through the filter net 44, causing the seeds to fall through the filter net 44 and finally enter the collection box 53. Finally, personnel can monitor the seeds in real time using a weighing sensor 55 and a camera 56.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
