[0003] It is found in Gansu Province, southeastern Sichuan Province, western and northwestern Guizhou Province, northeastern and northwestern Yunnan Province, and Tibet Autonomous Region. It grows in dry-hot valleys and hillside thickets at altitudes of 1400-2700(-3400) meters. Currently, *Hymenochloa chinensis* is mainly used in medical research. Its extracts and chemical components have effects such as promoting cell differentiation, anti-inflammation, antibacterial, antioxidant, and preventing gallstones. Clinically, it is used to treat hepatitis and gallstones with significant efficacy. At the same time, *Hymenochloa chinensis* is also a pioneer plant in arid valleys, with high ornamental value. It is drought-tolerant, heat-tolerant, and tolerant of poor soil, making it suitable for slope revegetation. However, current research on its seed sowing methods is limited, its germination characteristics are rarely studied, and its plant propagation methods are immature, resulting in a lack of plant material for slope revegetation in engineering projects. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a method and apparatus for sowing and treating seeds with two hairy ends.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] This invention discloses a seed-sowing and processing device for seeds with two hairs, including a processing box. A hair-grinding mechanism is provided near the opening of the processing box. A flipping mechanism is provided on the hair-grinding mechanism so that the seeds and seed hairs in the hair-grinding mechanism fall onto a mesh plate below the hair-grinding mechanism. The hair-grinding mechanism is driven by a driving mechanism to reciprocate along the mesh plate so that the ground-off seeds and seed hairs fall evenly into the seed box through the mesh plate.
[0007] Preferably, the sanding mechanism includes a rotating roller, a rotating shaft passing through the center of the rotating roller, sleeves at both ends of the rotating roller, and the two ends of the rotating shaft extending out of the sleeves and spaced apart from the sleeves and the rotating roller. An arc-shaped grinding plate is sleeved on the rotating roller, and the grinding plate has end plates at both ends. The sleeves pass through the end plates and are fixed by bearings. A main gear is fixedly sleeved on one of the sleeves, and the rotating roller is driven to rotate by driving the main gear to rotate.
[0008] Preferably, the portion of the rotating roller that overlaps with the grinding plate has multiple protrusions arranged randomly. The grinding plate and the rotating roller have the same axis. The central angle of the grinding plate is 180°. A connecting cylinder is provided on the end plate of another sleeve. The rotating shaft extends out of the connecting cylinder. A drive gear is fixedly fitted on the connecting cylinder. Brush bristles are provided on the top of the rotating roller along its length.
[0009] Preferably, the driving mechanism includes lead screws disposed on both outer sides of the processing box, lead screws being provided with lead screw nuts, a third motor being provided at one end of the lead screws, a retaining element being detachably disposed on the lead screw nuts, a connecting block being provided on the outer wall of the retaining element, the connecting block being fixed to the rotating shaft respectively, and channels for the rotating shaft to move being provided on both sides of the processing box, the channels being arranged in the same direction as the lead screws.
[0010] Preferably, drive boxes are respectively provided on both outer sides of the processing box, the drive mechanism is provided in the drive box, the sleeve and the connecting cylinder respectively extend into the drive box through the channel, one of the drive boxes is provided with a first motor, the gear on the first motor meshes with the main gear; the other drive box is provided with the flipping mechanism.
[0011] Preferably, the flipping mechanism includes a combined rack consisting of the back sides of two racks joined together, arranged along the length of the lead screw. In the initial position, the combined rack is located above the drive gear. Connecting bars are provided at both ends of the combined rack, and guide posts are provided through the connecting bars. One end of the guide post is provided on the slider of the slide rail. The slide rail is arranged in the same direction as the combined rack. A spring is sleeved on the guide post between the connecting bars and the slide rail. The combined rack is driven to move downward by a cam on the second motor, so that the combined rack meshes with the drive gear.
[0012] Preferably, a partition is arranged horizontally inside the drive box, and a U-shaped frame is symmetrically arranged on the bottom surface of the partition along the length of the lead screw. The slide rail is arranged on the bottom crossbar of the U-shaped frame and is perpendicular to the crossbar. The second motor is arranged on the top surface of the partition. The partition is provided with a through hole so that the combined rack and pinion meshes with the cam. The cam is fan-shaped and its edge is provided with gear teeth that can mesh with the combined rack and pinion.
[0013] Preferably, a conveying mechanism with both ends penetrating the processing box is provided below the mesh plate. The seed box is placed on the conveying mechanism. A guide groove extending towards the top opening of the seed box is provided on the inner wall of the processing box above the seed box. A liftable pad and a filter screen are arranged sequentially from bottom to top inside the seed box. A connecting rod for passing through the filter screen is provided at the bottom center of the pad. A water outlet is provided at the bottom of the seed box. Holes for conveying the seed box through the conveying mechanism are provided on the side wall of the processing box.
[0014] Correspondingly, a method for sowing seeds with two-end hairs involves placing the seeds into a grinding plate, starting a first motor to drive a rotating roller to rotate, and controlling the rotating roller to rotate less than 180° each time, alternating between clockwise and counterclockwise rotations to grind off the filamentous hairs on the seeds. Then, starting a second motor, during the rotation, causes a cam to mesh with a combined rack. As the cam rotates, the combined rack moves downward and meshes with a drive gear. Simultaneously, the combined rack moves linearly under the action of the cam, driving the drive gear to rotate, keeping the grinding plate above the rotating roller, and pouring the seeds and hairs onto a screen.
[0015] Start the third motor, the lead screw drives the lead screw nut, causing the rotating roller to move in a straight line along the lead screw. The bristles spread the seeds and seed hairs evenly on the screen and fall into the seed box.
[0016] Slowly inject disinfectant into the seed box, then lift the connecting rod to filter the solution and drain it through the outlet. Repeat this process, slowly inject water into the seed box, and rinse 2-3 times before draining. After rinsing, soak the seed box in water for 12-20 hours and allow it to germinate at a temperature of 20-25℃.
[0017] Preferably, after soaking, the sample is soaked in gibberellin at a concentration of 50–200 mg / L for 0.5–1 hour.
[0018] The present invention has the following beneficial effects:
[0019] 1. This invention discloses an apparatus for treating seeds with hairs at both ends. Since the hairs on the seeds at both ends are numerous and long, they affect the seed's absorption and germination. Therefore, the treatment apparatus separates the hairs from the seeds, thereby enabling the seeds to germinate better.
[0020] 2. This invention utilizes a grinding plate and rotating rollers within the processing chamber. The seeds, along with the protrusions on the rollers, are separated from their hairs by the grinding plate. Simultaneously, the friction generated during the hair removal process roughens the seed coat, making it more prone to swelling and shortening the swelling time. After grinding, the seeds are poured onto a mesh plate by a turning mechanism, and then spread out by a brush under the action of a screw, falling into a seed box. There, they undergo subsequent disinfection, cleaning, and germination, achieving a germination rate of over 90%. After germination, the entire filter screen is directly transferred to the soil for further growth. Once true leaves emerge, the seeds are transplanted. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Unless otherwise specified, the technical means used in the implementation examples are conventional means well known to those skilled in the art.
[0033] refer to Figures 1-9 This invention discloses a sowing and treatment device for seeds with two hairs at both ends. These seeds are small and have filamentous hairs at both ends. During germination, these hairs can affect seed imbibition; therefore, they need to be removed to increase the germination rate. The device includes a treatment box 1 with an opening at the top. A hair-removing mechanism is located near the opening of the treatment box 1. Initially, the hair-removing mechanism is located on one side of the treatment box, close to the box wall. A flipping mechanism is provided on the hair-removing mechanism, causing the seeds and hairs inside the mechanism to fall onto a mesh plate 2 below it. The flipping mechanism drives the hair-removing mechanism to rotate, causing the seeds and hairs to fall onto the mesh plate. The aperture of the mesh plate 2 is larger than the length of the two-headed hair seeds to facilitate their falling into a seed box 3 after hair removal. A driving mechanism then drives the hair-removing mechanism to reciprocate along the mesh plate 2, causing the removed seeds and hairs to fall evenly into the seed box 3.
[0034] Furthermore, the screen is inserted into the processing box, with one end extending out of the processing box, making it easy to replace screens with different aperture sizes and also facilitating maintenance.
[0035] Furthermore, the sanding mechanism includes a rotating roller 4, with a rotating shaft 5 passing through its axis. The rotating roller and the rotating shaft are spaced apart. Sleeves 6 are provided at both ends of the rotating roller 4. Both ends of the rotating shaft 5 extend out of the sleeves 6 and are spaced apart from the sleeves 6 and the rotating roller 4, i.e., the rotating roller, the rotating shaft, and the sleeves are coaxially arranged. An arc-shaped grinding plate 7 is sleeved on the rotating roller 4. The grinding plate 7 has end plates 8 at both ends. The sleeves 6 pass through the end plates 8 and are fixed by bearings. Specifically, the end plates 8 are provided with holes, and bearings are fixed in the holes. The sleeves pass through the inner ring of the bearings and are fixed, so that when the sleeves and the rotating roller rotate, the grinding plate does not move. The grinding plate 7 is coaxially arranged with the rotating roller, and the central angle of the grinding plate 7 is 180°. It is located at the bottom of the rotating roller. Multiple protrusions are randomly arranged on the part of the rotating roller 4 that overlaps with the grinding plate 7. These protrusions are preferably made of a soft and elastic material such as rubber to avoid damaging the seeds. By rotating the rotating roller, it rotates within the grinding plate, and in conjunction with the protrusions, the seed hairs on the seeds are removed. Of course, to enhance the polishing effect, fine sand can be added to the grinding plate. To drive the rotating roller 4, a main gear 9 is fixedly mounted on one of the sleeves 6. Driving the main gear 9 causes the rotating roller 4 to rotate. The main gear is driven by the first motor 20.
[0036] Furthermore, a connecting cylinder 10 is provided on the end plate 8 of another sleeve 6. One end of the connecting cylinder 10 is fixed to the end plate 8 and located in the outer ring area of the bearing on the end plate 8, so that the rotation of the connecting cylinder drives the grinding plate to rotate. One end of the rotating shaft 5 extends out of the connecting cylinder 10. A drive gear 11 is sleeved and fixed on the connecting cylinder 10. The flipping mechanism drives the drive gear 11 to rotate, which drives the grinding plate 7 to rotate. The main gear 9 rotates, which drives the rotating roller 4 to rotate. The top of the rotating roller 4 is provided with bristles 12 along its length. The height of the bristles should extend beyond the grinding plate. At the same time, the bottom surface of the grinding plate is in contact with the top surface of the screen plate. When the grinding plate and the rotating roller rotate and the bristles face down, the bristles can contact the surface of the screen plate, so as to contact the mixture of seeds and seed hairs. According to the usage of the device of the present invention, both the rotating roller 4 and the grinding plate 7 rotate 180°. After the brush is ground, it needs to be poured onto the screen plate. Therefore, it is necessary to drive the rotating roller and the grinding plate to rotate so that the brush bristles of the rotating roller face downwards and the opening of the grinding plate faces downwards. The two can rotate simultaneously or staggered, depending on the actual situation. After the grinding plate and the brush bristles face downwards, the rotating roller can be rotated again to make the seeds and seed hairs in the grinding plate fall off cleanly.
[0037] Furthermore, the drive mechanism includes lead screws 13 disposed on both outer sides of the processing box 1. The direction of the lead screws 13 is parallel to the direction of the rotating shaft, and the two lead screws are parallel to each other. A nut 14 is disposed on each lead screw 13, and a third motor 15 is disposed at one end of each lead screw 13. During use, the third motors start simultaneously. A retaining piece 16 is detachably disposed on the nut 14. The retaining piece 16 is an open arc shape, which can be directly engaged with the nut under external force to prevent it from falling off. A connecting block 17 is disposed on the outer wall of the retaining piece 16. The connecting block 17 is fixed to the rotating shaft 5. Specifically, an L-shaped notch is provided at the connection end of both the connecting block and the rotating shaft, and the two overlap and are fixed together with bolts, facilitating disassembly and installation. Channels 18 for the movement of the rotating shaft 5 are provided on both sides of the processing box 1, and the channels 18 are arranged in the same direction as the lead screws 13. As the lead screw 13 carries the abrasive mechanism in a linear motion within the processing box, it reciprocates along the channel, spreading the piled-up seeds and seed hairs onto the mesh plate through the brush bristles, and allowing them to fall through the mesh.
[0038] Furthermore, to protect the equipment, drive boxes 19 are respectively provided on both outer sides of the processing box 1. The drive boxes may have an open top or a cover, and their length is the same as the length of that side of the processing box. The drive mechanism (or lead screw 13) is set inside the drive box 19. One end of the lead screw is rotatably connected to the drive box, and the other end extends out of the box and is equipped with a third motor 15. The sleeve 6 and the connecting cylinder 10 respectively extend into the drive box 19 through the channel 18. One drive box 19 is equipped with a first motor 20, and the gear on the first motor 20 meshes with the main gear 9 to drive the rotating roller to rotate. The other drive box 19 is equipped with a flipping mechanism, which can mesh with the drive gear 11 when started.
[0039] Furthermore, the flipping mechanism includes a combined rack 21 formed by the back sides of two racks merging together, arranged along the length of the lead screw 13; that is, the combined rack 21 has teeth on both its upper and lower surfaces. In the initial position, the combined rack 21 is positioned above the drive gear 11, separated from it. Connecting bars 22 are provided at both ends of the combined rack 21, and guide posts 23 are threaded through the connecting bars 22. The number of guide posts 23 is determined as needed. The bottom ends of the guide posts 23 are mounted on the slider of the slide rail 24, allowing them to move along the slide rail. The slide rail 24 is oriented in the same direction as the combined rack 21. Springs 25 are fitted onto the guide posts 23 between the connecting bars 22 and the slide rail 24. The combined rack 21 is driven downwards by a cam 27 on the second motor 26, causing it to mesh with the drive gear 11. It should be noted that the slide rails and guide posts at both ends of the combined rack are arranged in an array, such as... Figure 9 As shown, the guide posts are all located on the right side of the slide rail, or the left side is also acceptable.
[0040] Furthermore, a partition 28 is horizontally arranged inside the drive box 19. A U-shaped frame 29 is symmetrically arranged on the bottom surface of the partition 28 along the length of the lead screw 13. The U-shaped frame 29 supports the slide rail. The slide rail 24 is mounted on the bottom crossbar of the U-shaped frame 29 and is vertically fixed to the crossbar. The second motor 26 is mounted on the top surface of the partition 28. A through hole 30 is provided on the partition 28, corresponding to the combined rack, allowing the combined rack 21 to mesh with the cam 27. The cam 27 is fan-shaped, with teeth on its edges that can mesh with the combined rack 21. The length of the teeth on the cam is designed to drive the combined rack to travel a certain distance in a straight line and rotate the grinding plate to a suitable position, while the guide post moves within the stroke of the slide rail. When the cam teeth disengage from the combined rack, the combined rack separates from the drive gear under the action of a spring. At this point, the third motor can be started, driving the entire grinding mechanism to reciprocate via the lead screw.
[0041] Furthermore, a conveying mechanism 34, extending through the processing box 1 at both ends, is provided below the mesh plate 2 to facilitate the transport of processed seeds. This conveying mechanism, being existing technology, mainly includes rollers and a conveyor belt. The seed box 3 is placed on the conveying mechanism 34, and holes 33 are provided on the side wall of the processing box 1 for transporting the seed box 3 via the conveying mechanism 34. Both ends of the conveying mechanism extend beyond the holes 33 and are fixed to the outer wall of the processing box, allowing the seed box to be output from the processing box. A guide groove 31, extending towards the top opening of the seed box 3, is provided on the inner wall of the processing box 1 above it to prevent seeds and seed hairs from falling to the bottom of the processing box. The guide groove is inclined and has side guards on both sides. It should be noted that when seeds fall into the seed box, even with the action of the brush bristles, the seeds will not fall very evenly through the mesh plate. Therefore, it is only necessary to ensure that the seeds falling into the seed box do not pile up.
[0042] Furthermore, inside the seed box 3, from bottom to top, there are liftable pads and filters. The mesh size of the filter is smaller than the length of the seed to prevent the seed from leaking out. The mesh size of the pad is smaller than the mesh size of the filter to further prevent the seed from leaking out. At the same time, the filter and pad can filter out fine seed hairs.
[0043] Furthermore, a connecting rod 32 for passing through a filter screen is provided at the center of the bottom of the pad, and a water outlet with a sealing plug is provided at the bottom of the seed box 3. In use, the pad and filter screen are removed from the seed box by lifting the connecting rod, and the filter screen and seeds on it are completely removed for cultivation. Alternatively, the filter screen can be removed after seed germination before further cultivation. This also facilitates the measurement of seed germination rate. The filter screen can be made of biodegradable material to prevent roots from becoming entangled on the filter screen after the seeds develop true leaves, which would hinder transplanting or damage the root system.
[0044] This invention discloses a method for sowing seeds with two hairs at both ends, the specific process of which is as follows:
[0045] (1) Place the seeds from both ends into the grinding plate 7, start the first motor 20 to drive the rotating roller 4 to rotate, and control the rotating roller 4 to rotate less than 180° each time, preferably less than 90°, and alternate between clockwise and counterclockwise rotation to prevent the seeds from being carried out of the grinding plate during the rotation of the rotating roller. To alleviate this problem, shims can be set at the open end of the grinding plate, with the shims facing the rotating roller and in contact with the rotating roller, which can ensure to a certain extent that the seeds do not fall out of the grinding plate.
[0046] (2) After the filamentous hairs on the seeds are ground off, the second motor 26 is started. During its rotation, the cam 27 meshes with the combined rack 21. As the cam 27 rotates, the combined rack 21 moves downward and meshes with the drive gear 11. Simultaneously, as the cam continues to mesh with and rotate the combined rack, the combined rack 21 moves linearly along the slide rail under the action of the cam 27, driving the drive gear 11 to rotate, causing the grinding plate 7 to rotate above the rotating roller 4. During this process, the first motor 20 is started simultaneously, driving the rotating roller to rotate, so that the tips of the bristles contact the screen plate. If the seeds and hairs are not completely removed, the first motor is started again, causing the rotating roller to rotate clockwise and counterclockwise alternately for less than 180°, finally pouring the seeds and hairs onto the screen plate 2.
[0047] (3) Start the third motor 15. The lead screw 13 drives the lead screw nut 14, causing the rotating roller 4 to reciprocate along the lead screw 13. At this time, the bristles 12 spread the seeds and seed hairs evenly on the mesh plate 2 and fall into the seed box 3. Specifically: During the movement of the bristles, the seeds and seed hairs may fall off relatively quickly and not be spread evenly. This phenomenon has no impact. Just make sure that the seeds do not pile up in the seed box.
[0048] (4) After the seeds and seed hairs have completely fallen off, the seed box is transported to the outside of the treatment box via a conveying mechanism. Then, disinfectant (75% ethanol) is slowly injected into the seed box 3, and the connecting rod 32 is raised for filtration. The filtrate is then discharged through the water outlet. Following this operation, water is slowly injected into the seed box 3 to wash it 2-3 times and then discharged to remove the small floating hairs and disinfectant from the seeds. After washing, the seeds are soaked in water for 12-20 hours and germinated at a temperature of 20-25°C. Further, after soaking, the seeds are soaked in gibberellin at a concentration of 50-200 mg / L for 0.5-1 hour. During the seed germination process, multiple seed boxes can be stacked together and germinated in a heat preservation box, achieving a germination rate of over 90%.
[0049] (5) After the seeds germinate, lift the connecting rod to remove the germinated seeds from the seed box, remove the filter screen along with the germinated seeds, place them in the watered soil, and cover them with fine sand or fine soil to a thickness of about 2cm. When true leaves grow, they can be transplanted.

The slide rail (24) is provided on the bottom crossbar of the U-shaped frame (29) and is perpendicular to the crossbar. The second motor (26) is provided on the top surface of the partition (28). The partition (28) is provided with a through hole (30) so that the combined rack (21) meshes with the cam (27). The cam (27) is fan-shaped and its edge is provided with gear teeth that can mesh with the combined rack (21).
4. The seed-sowing and processing device for two-headed hairy seeds according to claim 1, characterized in that: Below the mesh plate (2) is a conveying mechanism (34) that passes through the processing box (1) at both ends. The seed box (3) is placed on the conveying mechanism (34). On the inner wall of the processing box (1) above the seed box (3), there is a guide groove (31) extending one end toward the top opening of the seed box (3). Inside the seed box (3), there are liftable pads and filter screens arranged sequentially from bottom to top. A connecting rod (32) that passes through the filter screen is arranged at the bottom center of the pad. A water outlet is arranged at the bottom of the seed box (3). A hole (33) is arranged on the side wall of the processing box (1) for conveying the seed box (3) through the conveying mechanism (34).
5. A method for processing seeds with two ends of hair according to any one of claims 1 to 4, characterized in that: Place the two-headed hairy seeds into the grinding plate (7), start the first motor (20), drive the rotating roller (4) to rotate, and control the rotating roller (4) to rotate less than 180° each time, and alternate between clockwise and counterclockwise to grind off the filamentous hairs on the seeds. Then start the second motor (26), and during the rotation, make the cam (27) mesh with the combined rack (21). As the cam (27) rotates, the combined rack (21) moves downward and meshes with the drive gear (11). At the same time, the combined rack (21) moves linearly under the action of the cam (27), driving the drive gear (11) to rotate, so that the grinding plate (7) is kept above the rotating roller (4), and the seeds and hairs are poured out onto the screen plate (2). Start the third motor (15), the lead screw (13) drives the nut (14), so that the rotating roller (4) moves in a straight line along the lead screw (13), and the bristles (12) spread the seeds and seed hairs on the mesh plate (2) and fall into the seed box (3); Slowly inject disinfectant into the seed box (3) and then lift the connecting rod (32) to filter it and discharge it through the water outlet. Following this operation, slowly inject water into the seed box (3) and wash it 2 to 3 times before discharging. After washing, soak it in water for 12 to 20 hours and germinate at a temperature of 20 to 25°C.
6. The method for sowing and treating seeds with two hairs according to claim 5, characterized in that: After soaking, soak in gibberellin at a concentration of 50–200 mg / L for 0.5–1 hour.
