Abstract
Description
Technical Field
[0001] This invention relates to the field of flower propagation equipment technology, specifically to an artificial pollination device for peony seedling propagation equipped with a precise pollen spraying component. Background Technology
[0002] In the field of agricultural plant propagation, peony, as an important ornamental and economic crop, has its seedling propagation quality directly affected by the efficiency and success rate of artificial pollination. Currently, traditional techniques for artificial pollination in peony seedling propagation mainly have the following problems: Low pollen processing efficiency and insufficient purity: Existing pollination devices usually lack efficient pollen sieving mechanisms, and impurities (such as petal fragments, dust, etc.) are easily mixed into the pollen, causing impurities to clog the spray channel during pollination. At the same time, low-purity pollen will affect the pollination success rate. In addition, traditional sieving methods mostly rely on manual operation or simple mechanical vibration, which has low sieving efficiency and makes it difficult to ensure pollen activity. Poor pollination accuracy and serious waste: Traditional spraying devices mostly use extensive spraying, which cannot accurately control pollen, dosage and range. In particular, it is difficult to achieve targeted pollination of peony stamens at different growth stages, resulting in a high pollen waste rate and easy pollution of non-target areas. Insufficient environmental adaptability and automation: Pollen activity is sensitive to temperature and humidity. Existing devices lack real-time environmental monitoring and control functions, which cannot guarantee the activity of pollen during storage. At the same time, most devices are fixed structures, which are inconvenient to move and cannot meet the needs of efficient operation in large-scale breeding scenarios.
[0003] To address the aforementioned problems, this invention proposes an artificial pollination device for peony seedling propagation equipped with a precise pollen spraying component. Summary of the Invention
[0004] To address the problems in the prior art, this invention provides an artificial pollination device for peony seedling propagation with a precise pollen spraying component. In order to solve the aforementioned problems, this invention proposes an artificial pollination device for peony seedling propagation with a precise pollen spraying component, which solves the problems of low efficiency, poor accuracy, and weak environmental adaptability in the existing technology.
[0005] The technical solution adopted by this invention to solve its technical problem is: an artificial pollination device for peony seedling propagation with a pollen precision spraying component, comprising a storage box and a sieving box interconnected by pipes. The upper ends of both the storage box and the sieving box are connected to a cover plate via movable snap-fit. A temperature sensor and a humidity sensor are installed inside the storage box. A drive motor is fixedly connected to the bottom of the sieving box via a bracket. The output end of the drive motor is fixedly connected to a first rotating rod. The first rotating rod is rotatably connected to the sieving box via a bearing. A first bevel gear is fixedly connected to the top of the first rotating rod, and a cleaning plate with a cleaning brush at its lower end is fixedly connected to the lower wall of the first rotating rod. A second rotating rod is rotatably connected to the middle of the sieving box via a bearing. A second bevel gear is fixedly connected to the wall of the second rotating rod, and the second bevel gear meshes with the first bevel gear. Cranks are installed on both sides of the second rotating rod. A filter plate is hinged to the upper end of the crank via a pin. First sliding grooves are formed on both inner walls of the upper end of the sieving box. Slide plates are fixedly connected to both sides of the filter plate, and the opposite side of the slide plates is slidably connected within the first sliding groove.
[0006] Specifically, one side of the second rotating rod extends to the outside of the screening box and is fixedly connected to the first sprocket. The lower end of the first sprocket meshes with the second sprocket. The second sprocket is fixedly connected to the inside of the third rotating rod. The third rotating rod is rotatably connected to the inside of the screening box through a bearing, and the side of the third rotating rod away from the second sprocket is fixedly connected to the drive fan blade.
[0007] Specifically, a corrugated telescopic pipe with an electric valve is fixedly connected to the lower end of the storage box. A pump is fixedly connected to the lower end of the corrugated telescopic pipe, and a spray pipe is fixedly connected to the other end of the pump. A stepper motor is fixedly connected to the lower end of the pump. A protective cover is fixedly connected to the lower end of the stepper motor via a bracket. A second sliding groove is opened in the inner wall of the protective cover, and the spray pipe passes through the upper side wall of the protective cover and extends into the interior of the protective cover. A drive rod is fixedly connected to the output end of the stepper motor. The drive rod is rotatably connected to the middle of the protective cover via a bearing, and a third bevel gear is fixedly connected to the lower end of the drive rod. A screw arranged in a circular array is rotatably connected to the inner wall of the protective cover via a bearing. A fourth bevel gear is fixedly connected to the other side of each screw. The fourth bevel gear meshes with the third bevel gear, and a screw sleeve is threaded to the wall of each screw. A sliding rod is fixedly connected to the upper end of each screw sleeve. The upper end of the sliding rod is slidably connected in the second sliding groove. A support plate is fixedly connected to the lower end of each screw sleeve.
[0008] Specifically, an adjustable shoulder strap is fixedly connected to one side of the storage box.
[0009] Specifically, retaining rings are fixedly connected to both the upper and lower ends of the filter plate.
[0010] Specifically, the first and second bevel gears are fitted with protective sleeves, which are fixedly connected to the inner wall of the screening box by a bracket.
[0011] Specifically, the pump is fastened to the lower end of the storage box by a movable buckle.
[0012] The beneficial effects of this invention are: (1) The artificial pollination device for peony seedling breeding with a pollen precision spraying component described in this invention has a filter plate installed in the middle of the sieving box. The filter plate achieves reciprocating sieving motion through a crank-connecting rod mechanism to separate pollen from impurities. The cleaning plate in the lower space rotates with the first rotating rod and pushes the sieving pollen along the trajectory below the filter plate in a non-contact manner. In this upper and lower layered structure, the filter plate is responsible for precise sieving, while the cleaning plate guides the pollen towards the storage box through circumferential rotation. Combined with the airflow generated by the fan blades in the sieving box, a three-dimensional conveying mechanism of "upper layer sieving - lower layer pushing - airflow assistance" is formed to increase the overall pollen processing efficiency. (2) The artificial pollination device for peony seedlings with a precise pollen spraying component described in this invention has a screw mechanism under the storage box that drives the expansion plate to expand radially. After the petals are pushed open, the spraying pipe fixed inside the protective cover is directly facing the center of the flower. Since the position of the spraying pipe is rigidly fixed by the protective cover and is located at the end of the material conveying path between the cleaning plate and the filter plate, it can ensure that high-purity pollen is directly sprayed to the stigma after screening and pushing. This structure utilizes the full-process linkage of "filter plate screening - cleaning plate pushing - screw pushing plate opening petals - fixed spraying pipe pollination" to solve the problem of pollination blind spots caused by petal obstruction or spraying angle deviation in traditional devices. It is especially suitable for precise operation of double-petaled peony varieties. (3) The artificial pollination device for peony seedling propagation with a pollen precision spraying component described in this invention has an upper and lower layered layout of filter plate and cleaning plate, which, together with the temperature and humidity sensor built into the storage box, forms an integrated system of "screening-storage-environmental monitoring". After the upper filter plate completes pollen screening, the lower cleaning plate and fan blades work together to introduce pollen into the storage box. The storage box moves according to the temperature and humidity data via a shoulder strap. This design enables the device to achieve continuous operation of "dynamic screening-environmental adaptation-flexible movement" in complex terrains such as terraces and slopes through functional zoning of the upper and lower spaces. Compared with traditional fixed devices, the operating efficiency in large-scale nurseries is significantly improved. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0017] like Figures 1-7 As shown, the present invention provides the following technical solution: Example 1: An artificial pollination device for peony seedling propagation with a precise pollen spraying component, comprising a storage box 1 and a sieving box 2 interconnected by pipes. Both storage box 1 and sieving box 2 have covers connected to their upper ends by movable clips. Storage box 1 is equipped with a temperature sensor and a humidity sensor. An adjustable carrying strap 30 is fixedly connected to one side of storage box 1. A drive motor 3 is fixedly connected to the bottom of sieving box 2 via a bracket. The output end of drive motor 3 is fixedly connected to a first rotating rod 4. The first rotating rod 4 is rotatably connected to sieving box 2 via bearings. A first bevel gear 5 is fixedly connected to the top of the first rotating rod 4, and a cleaning plate with a cleaning brush at its lower end is fixedly connected to the lower wall of the first rotating rod 4. 6. The middle part of the screening box 2 is rotatably connected to the second rotating rod 7 via a bearing. The second rotating rod 7 is fixedly connected to the second bevel gear 8. The second bevel gear 8 is meshed with the first bevel gear 5. The first bevel gear 5 and the second bevel gear 8 are covered with protective sleeves. The protective sleeves are fixedly connected to the inner wall of the screening box 2 via a bracket. Cranks 9 are installed on both sides of the second rotating rod 7. The upper end of the crank 9 is hinged to the filter plate 10 via a pin. The upper and lower ends of the filter plate 10 are fixedly connected to retaining rings. The inner walls on both sides of the upper end of the screening box 2 are provided with first sliding grooves 11. Slide plates 12 are fixedly connected to both sides of the filter plate 10. The opposite side of the slide plates 12 is slidably connected in the first sliding grooves 11. The second rotating rod 7 extends one side of its wall to the outside of the screening box 2 and is fixedly connected to the first spur gear 13. The lower end of the first spur gear 13 is meshed with the second spur gear 14. The third rotating rod 15 is fixedly connected inside the second spur gear 14. The third rotating rod 15 is rotatably connected inside the screening box 2 through a bearing, and the side of the third rotating rod 15 away from the second spur gear 14 is fixedly connected to the drive fan blade 16.
[0018] In use, first connect the controllers of the temperature and humidity sensors to the outside of the storage box 1, then open the movable buckle at the top of the sieving box 2, remove the cover plate, and pour the peony pollen to be processed into the sieving box 2 so that the pollen is evenly covered on the surface of the filter plate 10. The temperature and humidity sensors inside the storage box 1 are activated in conjunction with the external controller to monitor the environmental parameters in real time (the temperature needs to be maintained at 20-25℃, and the humidity at 40%-60%). If the parameters are abnormal, they can be adjusted in conjunction with the external control. The device is carried on the operator's back using the shoulder strap 30 on one side of the storage box 1. The device is then moved to the target work site. The drive motor 3 at the bottom of the screening box 2 is started via an external power supply. Its output drives the first rotating rod 4 to rotate clockwise. The cleaning plate 6 at the lower end of the first rotating rod 4 rotates with the rod, and the first bevel gear 5 at the top of the first rotating rod 4 rotates synchronously, meshing with the second bevel gear 8, driving the second rotating rod 7 to rotate counterclockwise. The protective sleeve (fixed to the inner wall of the screening box 2 by a bracket) prevents... When impurities are mixed in during gear transmission, the cranks 9 on both sides of the second rotating rod 7 are hinged to the filter plate 10 through the pin shaft, which drives the slide plates 12 on both sides of the filter plate 10 to make reciprocating linear motion in the first slide groove 11 on the inner wall of the screening box 2, so as to realize the screening of pollen and impurities. The retaining rings at the upper and lower ends of the filter plate 10 prevent pollen from overflowing during the screening process. Impurities are left on the plate, and pure pollen falls through the sieve holes to the bottom of the filter plate 10. At this time, the cleaning brush at the bottom of the cleaning plate 6 rotates in a cycle, pushing the screened pollen towards the storage box 1. Meanwhile, the first sprocket 13, which extends from the second rotating rod 7 to the outside of the screening box 2, drives the second sprocket 14 to rotate, and the third rotating rod 15 drives the fan blade 16 to rotate, forming a directional airflow in the screening box 2. In conjunction with the pushing action of the cleaning plate 6, the pollen is introduced into the storage box 1 through the pipe, completing the three-dimensional conveying of "upper layer screening - lower layer pushing - airflow assistance".
[0019] Example 2: The technical solution of this example, which differs from Example 1, includes: a corrugated telescopic pipe 17 with an electric valve is fixedly connected to the lower end of the storage box 1; a pump 18 is fixedly connected to the lower end of the corrugated telescopic pipe 17; a spray pipe 22 is fixedly connected to the other end of the pump 18; a stepper motor 19 is fixedly connected to the lower end of the pump 18; a protective cover 20 is fixedly connected to the lower end of the stepper motor 19 via a bracket; a second sliding groove 21 is opened on the inner wall of the protective cover 20; and the spray pipe 22 penetrates the upper side wall of the protective cover 20 and extends into the interior of the protective cover 20; a drive rod 23 is fixedly connected to the output end of the stepper motor 19; and the drive rod 23 is connected via a shaft. The bearing is rotatably connected to the middle of the protective cover 20, and the lower end of the drive rod 23 is fixedly connected to the third bevel gear 24. The inner wall of the protective cover 20 is rotatably connected to the screws 25 arranged in a circular array through the bearing. The other side of the screws 25 is fixedly connected to the fourth bevel gear 26, which meshes with the third bevel gear 24. The screws 25 are threadedly connected to the sleeves 27. The upper end of the sleeves 27 is fixedly connected to the slide rod 28, which slides in the second slide groove 21. The lower end of the sleeves 27 is fixedly connected to the expansion plate 29. The pump 18 is fastened to the lower end of the storage box 1 by a movable buckle.
[0020] In use, the pump 18 and the connected structure are removed from the lower end of the storage box 1 by means of the movable buckle. The corrugated telescopic tube 17 connected to it will facilitate the movement of the protective cover 20. Then, it is aligned with the peony that needs to be pollinated. At the same time, the expansion plate 29 will be inserted into the peony. The stepper motor 19 at the lower end of the storage box 1 is started by the external power supply. Its output end drive rod 23 drives the third bevel gear 24 to rotate and mesh with the fourth bevel gear 26 which is arranged in a circular array around it. This causes the screw 25 to rotate synchronously. The screw sleeve 27 on the screw 25 moves along the rod and drives the slide rod 28 to slide and limit in the second slide groove 21 on the inner wall of the protective cover 20. The expansion plate 29 at the lower end expands radially and slowly pushes open the petals to reveal the center of the flower stamen. At the same time, the pump 18 is started. The input end of the pump 18 draws pollen from the inside of the storage box 1 through the corrugated telescopic pipe 17 with an electric valve. The output end is connected to the spray pipe 22, which sprays the pollen out. The protective cover 20 rigidly fixes the spray pipe 22 to ensure that it is accurately aligned with the stigma after the expansion plate 29 is activated. Adjusting the speed of the stepper motor 19 controls the expansion range of the expansion plate 29, adapting to the petal thickness of different peony varieties; Adjusting the power of pump 18 controls the spray flow rate, and combining this with the temperature and humidity data in storage box 1 (such as reducing the spray volume when the humidity is high to avoid pollen clumping), thus completing the rapid pollination of peonies.
