Description

Technical Field

[0001] This utility model relates to the field of pollen collection technology, and in particular to a micro-pollen collector that also has the functions of pollen filtration and preservation. Background Technology

[0002] Mulberry is an important economic crop. Its male flowers produce small, light, and abundant pollen, making them wind-pollinated. Due to its pollen dispersal characteristics, artificial hybridization is typically used to create new germplasm resources during the breeding of new mulberry varieties to prevent cross-contamination between pollen from different varieties.

[0003] Existing technologies often suffer from the following drawbacks: Firstly, due to the extremely low natural pollen shedding rate of mulberry anthers, pollen obtained through bagging or manual puncturing of the anthers contains impurities, affecting pollen preservation. Therefore, filtering of the initially collected pollen is necessary, but this process typically involves multiple transfers and dumping of the pollen, leading to a loss of pollen quantity and viability. Secondly, humidity affects pollen viability; providing suitable preservation conditions is crucial for maintaining pollen viability and improving the quality of hybridization breeding.

[0004] Therefore, this utility model provides a micro-pollen collector that also functions as a pollen filter and preserver. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the extremely low natural pollen shedding rate of mulberry anthers, the presence of impurities in pollen obtained by bagging or manually puncturing the anthers, which easily affects pollen preservation, and the need for pollen filtration. However, the filtration process usually requires multiple pouring and transfer of pollen, leading to a loss of pollen quantity and viability. Therefore, a micro-pollen collector is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a micro-pollen collector, comprising a conical flask and a second storage cylinder, wherein a pollen outlet tube is connected to the side of the conical flask, and a first flexible tube is sleeved at the other end of the pollen outlet tube, and a first connecting tube is installed at the other end of the first flexible tube, the first connecting tube being slidably connected to the inner wall of the first flexible tube, a first filter cylinder is installed at the other end of the first connecting tube, the first filter cylinder being fixedly connected to the first connecting tube, a first storage cylinder is installed on the side of the first filter cylinder away from the first flexible tube, a second filter cylinder is installed on the side of the first storage cylinder away from the first filter cylinder, a first filter screen is installed on the side of the first filter cylinder close to the first storage cylinder, and a second filter screen is installed on the lower surface of both the first and second storage cylinders.

[0007] The effect achieved by the above components is that by attracting the pollen initially collected in the conical flask into the first filter tube and the first storage tube, the pollen can be filtered using the first filter screen.

[0008] Preferably, the first filter screen is a 100-mesh nylon filter screen, and the second filter screen is a 1000-mesh nylon filter screen.

[0009] The effects achieved by the above components are as follows: the first filter can filter the initially collected pollen, and the second filter can prevent the pollen from scattering during storage, while allowing it to come into contact with the air outside the storage container.

[0010] Preferably, the conical flask has an air inlet pipe connected to its side, and the surface of the air inlet pipe is covered with a filter screen.

[0011] The above-mentioned components achieve the following effects: the air inlet pipe ensures that gas is drawn out of the conical flask while preventing a vacuum from forming inside; the filter screen filters the air entering the conical flask.

[0012] Preferably, the side of the second filter cartridge away from the first storage cartridge is connected to a second connecting pipe, the surface of the second connecting pipe is covered with a second flexible tube, and a vacuum pump is installed at the other end of the second flexible tube. The input end of the vacuum pump is fixedly connected to the second flexible tube.

[0013] The effect achieved by the above components is as follows: when pollen needs to be filtered, the vacuum pump is activated, which can attract the pollen, thereby controlling the movement of the pollen and completing the filtration work.

[0014] Preferably, a cap is installed on the upper surface of the second storage cylinder, the external thread of the cap matches the internal thread of the second storage cylinder, and a bottom cylinder is installed on the lower surface of the second storage cylinder, the interior of which is filled with color-changing silica gel desiccant.

[0015] The effect achieved by the above components is that the second storage cylinder can be sealed by the set cap, and the color-changing silica gel desiccant in the bottom cylinder can provide a dry environment for the storage of pollen.

[0016] Preferably, a first connecting cylinder is detachably installed on the side of the first filter cylinder near the first storage cylinder. The external thread of the first connecting cylinder matches the internal threads of both the first and second storage cylinders. A second connecting cylinder is detachably installed on the lower surface of both the first and second storage cylinders. The internal threads of both the first and second storage cylinders match the external threads of the second connecting cylinder. An installation groove is provided inside both the first and second connecting cylinders.

[0017] The effect achieved by the above components is that the first filter cylinder and the first storage cylinder or the second storage cylinder can be connected through the first connecting cylinder, and the first storage cylinder or the second storage cylinder can be installed through the second connecting cylinder.

[0018] Preferably, the first filter cylinder, the second filter cylinder, and the bottom cylinder each have two sliding grooves on their sides. The surfaces of the sliding grooves on the first filter cylinder, the second filter cylinder, and the bottom cylinder are slidably connected to sliders. The surfaces of the first filter cylinder, the second filter cylinder, and the bottom cylinder are all fitted with movable rings. The movable rings have annular grooves inside. The side of the slider closest to the movable ring is fixedly connected to a limiting block. The limiting block is slidably connected to the surface of the annular groove. The side of the movable ring is fixedly connected to two side ears. The surfaces of the first connecting cylinder and the second connecting cylinder are both fixedly connected to fixed rings.

[0019] The effect achieved by the above components is that, through the set slider and limit block, the moving ring can be moved closer to or away from the fixed ring while allowing the moving ring to rotate.

Afterward, the second storage cylinder is removed and connected to the cap and the bottom cylinder, and the color-changing silica gel desiccant inside the bottom cylinder is used to keep the pollen dry.

[0028] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a micro-pollen collector, including a conical flask 1 and a second storage cylinder 13. A pollen outlet tube 4 is connected to the side of the conical flask 1. A first flexible tube 5 is sleeved at the other end of the pollen outlet tube 4. A first connecting tube 7 is installed at the other end of the first flexible tube 5, and the first connecting tube 7 is slidably connected to the inner wall of the first flexible tube 5. A first filter cylinder 6 is installed at the other end of the first connecting tube 7, and the first filter cylinder 6 is fixedly connected to the first connecting tube 7. A first storage cylinder 8 is installed on the side of the first filter cylinder 6 away from the first flexible tube 5. A second filter cylinder 9 is installed on the side of the first storage cylinder 8 away from the first filter cylinder 6. A first filter screen 21 is installed on the side of the first filter cylinder 6 close to the first storage cylinder 8. Second filter screens 22 are installed on the lower surfaces of both the first storage cylinder 8 and the second storage cylinder 13. By attracting the pollen initially collected in the conical flask 1 into the first filter cylinder 6 and the first storage cylinder 8, the first filter screen 21 can effectively filter it.

[0029] The following is a detailed explanation of its overall setup and function.

[0030] Reference Figures 1-4As shown in this embodiment: the first filter 21 is a 100-mesh nylon filter, and the second filter 22 is a 1000-mesh nylon filter. The first filter 21 filters the initially collected pollen, while the second filter 22 prevents pollen from scattering during storage and allows it to contact the air outside the storage container. An air inlet pipe 2 is connected to the side of the conical flask 1, and a filter screen cover 3 is fitted over the surface of the air inlet pipe 2. The air inlet pipe 2 ensures that gas is drawn out of the conical flask 1 while preventing a vacuum inside. The filter screen cover 3 filters the air entering the conical flask 1. A second connecting pipe 10 is connected to the side of the second filter cylinder 9 away from the first storage cylinder 8. A second flexible tube 11 is fitted over the surface of the second connecting pipe 10, and a vacuum pump 12 is installed at the other end of the second flexible tube 11. The input end of the vacuum pump 12 is fixedly connected to the second flexible tube 11. When pollen needs to be filtered, the vacuum pump 12 is activated, which can attract the pollen, thereby controlling the movement of the pollen and completing the filtration process.

[0031] A cap 15 is installed on the upper surface of the second storage cylinder 13. The external thread of the cap 15 matches the internal thread of the second storage cylinder 13. A bottom cylinder 14 is installed on the lower surface of the second storage cylinder 13, and a color-changing silica gel desiccant 23 is installed inside the bottom cylinder 14. The cap 15 can seal the second storage cylinder 13, while the color-changing silica gel desiccant 23 in the bottom cylinder 14 provides a dry environment for pollen storage. A first connecting cylinder 16 is detachably installed on the side of the first filter cylinder 6 near the first storage cylinder 8. The external thread of the first connecting cylinder 16 matches the internal threads of both the first storage cylinder 8 and the second storage cylinder 13. A second connecting cylinder 17 is detachably installed on the lower surface of both the first storage cylinder 8 and the second storage cylinder 13. The internal threads of both the first storage cylinder 8 and the second storage cylinder 13 match the external threads of the second connecting cylinder 17. Both the first connecting cylinder 16 and the second connecting cylinder 17 have mounting grooves 24 inside. The first connecting cylinder 16 allows connection between the first filter cylinder 6 and either the first storage cylinder 8 or the second storage cylinder 13. The second connecting cylinder 17 allows installation of either the first storage cylinder 8 or the second storage cylinder 13. Two sliding grooves are formed on the sides of the first filter cylinder 6, the second filter cylinder 9, and the bottom cylinder 14. Sliding blocks 25 are slidably connected to the surfaces of these grooves. Moving rings 19 are fitted onto the surfaces of the first filter cylinder 6, the second filter cylinder 9, and the bottom cylinder 14. An annular groove 27 is formed inside the moving ring 19. A limiting block 26 is fixedly connected to the side of the sliding block 25 near the moving ring 19, and the limiting block 26 is slidably connected to the surface of the annular groove 27. Two side ears 20 are fixedly connected to the side of the moving ring 19. Fixed rings 18 are fixedly connected to the surfaces of both the first connecting cylinder 16 and the second connecting cylinder 17. The sliding blocks 25 and the limiting blocks 26 ensure that the moving ring 19 can move closer to or away from the fixed ring 18 while also allowing the moving ring 19 to rotate.

[0032] Working principle: After initially collecting pollen of different varieties into the conical flask 1, the filter screen 3 is connected to the air inlet pipe 2 on the conical flask 1. Then, the first flexible tube 5 and the pollen outlet pipe 4 are connected. Next, the moving ring 19 on the first filter cylinder 6 and the second filter cylinder 9 is rotated using the side lug 20, causing the limiting block 26 to slide on the surface of the ring groove 27. Simultaneously, the slider 25 on the first filter cylinder 6 and the second filter cylinder 9 slides on the surface of the sliding groove on both, causing the moving ring 19 to move away from the fixed ring 18, thus releasing the connection between the first filter cylinder 6 and the second filter cylinder 9 and the first filter cylinder 18. Connect the first filter cylinder 16 and the second connecting cylinder 17, then rotate the first connecting cylinder 16 to separate it from the first storage cylinder 8. Replace the first filter screen 21, installing the unused first filter screen 21 into the mounting slot 24 inside the first connecting cylinder 16. Then connect the first filter cylinder 6 and the first connecting cylinder 16. The first filter cylinder 6 can then be used directly when processing the same type of pollen again. Separate the cap 15 and the second storage cylinder 13, then separate the bottom cylinder 14 and the second connecting cylinder 17 on the second storage cylinder 13. Connect the cap 15 to the first storage cylinder 8. Connect the first storage cylinder 8, move the first storage cylinder 8 so that the second connecting cylinder 17 on the first storage cylinder 8 is close to the bottom cylinder 14, rotate the moving ring 19 on the bottom cylinder 14 to connect the bottom cylinder 14 and the first storage cylinder 8. At this time, the color-changing silica gel desiccant 23 in the bottom cylinder 14 can provide a dry environment for the pollen storage in the first storage cylinder 8. Separate the second storage cylinder 13 and its second connecting cylinder 17, replace the second filter screen 22 and then reconnect the two. Move the second storage cylinder 13 close to the second filter cylinder 9, and connect the second filter cylinder 9 and the second connecting cylinder 17 on the second storage cylinder 13. Connect the connecting tube 17, move the unused first filter tube 6 and its first connecting tube 16 close to the second storage tube 13, connect the second storage tube 13 and it, connect the first hose 5 to the first connecting tube 7 on the first filter tube 6, connect the second hose 11 on the vacuum pump 12 to the second connecting tube 10 on the second filter tube 9, connect the external power supply to the vacuum pump 12, start the vacuum pump 12, so that the pollen initially collected in the conical flask 1 is filtered through the first filter tube 6 under the drive of the airflow and enters the second storage tube 13. By replacing the first filter cartridge 6 and the second storage cartridge 13 on the second filter cartridge 9, the pollen is drawn from the conical flask 1 through the first filter cartridge 6 and then into the second storage cartridge 13 using the vacuum pump 12, the second hose 11, and the second filter cartridge 9, thus achieving pollen filtration. Afterward, the second storage cartridge 13 is removed and connected to the cap 15 and the bottom cartridge 14. The color-changing silica gel desiccant 23 inside the bottom cartridge 14 keeps the pollen dry. The side lugs 20, the fixing ring 18, and the moving ring 19 make it easy to separate and combine the first connecting cartridge 16 and the first storage cartridge 8, the second filter cartridge 9, the bottom cartridge 14, the first storage cartridge 8, and the second storage cartridge 13, thereby facilitating the replacement of the first filter screen 21 and the second filter screen 22.
