Technical Field

[0001] This utility model relates to the field of maize pollination technology, and in particular to a pollen collection and preservation device for high-quality and high-yield maize breeding. Background Technology

[0002] In high-quality and high-yield maize breeding, pollen, as the male gamete, is the key carrier of genetic material. It is widely used in conventional hybridization breeding, biotechnology-assisted breeding, germplasm resource preservation, seed production, and basic research. Pollen collection and preservation devices for high-quality and high-yield maize breeding enable high-quality pollen to be used precisely and efficiently for planned hybridization under optimal conditions.

[0003] However, in existing technologies, after corn pollen is collected, it needs to be transferred from the collection device to a self-sealing bag for low-temperature preservation, which results in pollen loss during the transfer process. In addition, some corn flower organs fall into the collection bag during collection, requiring manual sorting to remove the internal corn flower organs, thus affecting efficiency.

[0004] Therefore, this application provides a pollen collection and preservation device for high-quality and high-yield maize breeding to solve the problems mentioned in the background art. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 — Figure 7 This utility model provides an embodiment of a pollen collection and preservation device for high-quality and high-yield maize breeding, comprising a shell 1, a fixed shell 2, a first support 6, and a second support 7. A placement rack 17 is fixedly installed on the lower end of the inner wall of the shell 1. A funnel 14 is slidably installed inside the placement rack 17. A mesh 15 is fixedly installed on the upper end face of the placement rack 17 by two bolts. A top cover 4 is hinged to the upper end face of the shell 1 by a pin. Semicircular grooves 5 are formed on the upper end face of the front end of the shell 1 and the lower end face of the front end of the top cover 4. The inner walls of the front and rear ends of the fixed shell 2 are... Two sliding rods 8 are fixedly installed on both sides of the inner wall. A rotating shaft 9 is rotatably installed on one side of the inner wall of the fixed shell 2 at the lower end of the sliding rod 8 via a bearing. A gear 11 is fixedly connected to the other end of the rotating shaft 9. A torsion spring 10 is sleeved around the rotating shaft 9. Sliding blocks 12 are fixedly installed at the rear corner of the upper end face on both sides of the outer wall of the first bracket 6 and at the front end of the upper end face on both sides of the outer wall of the second bracket 7. A rack 13 is fixedly installed in the middle of one side of the outer wall of the first bracket 6 and the second bracket 7. A push rod 3 is fixedly installed at the front end of the lower rack 13.

[0019] Specifically, when using the device, first press the push rod 3. The two racks 13 mesh with the gear 11, causing the first support 6 and the second support 7 to move towards the center, while simultaneously compressing the torsion spring 10. When the push rod can no longer be pressed, place the opening of the self-sealing bag over the first support 6 and the second support 7, then release the push rod 3. The torsion spring 10 rebounds, causing the gear 11 to rotate. The gear 11 meshes with the two racks 13, thus expanding the first support 6 and the second support 7 forward and backward. Simultaneously, the opening of the self-sealing bag is expanded. Then, open the top cover 4, place the funnel 14 inside the placement rack 17, and fix the mesh 15 to the upper end of the placement rack 17 with two bolts. Place the corn tassels inside the shell 1 and the corn stalks inside the semi-circular groove 5. Then, close the top cover 4. The magnetic attraction of the two magnetic strips 16 prevents the top cover 4 from opening on its own. Then, gently shaking the device, which also causes the corn florets to shake, allows the pollen to fall directly into the self-sealing bag through the funnel 14. Simultaneously, the mesh 15 intercepts the corn florets, preventing them from falling into the self-sealing bag as well. It should be noted that the torsion spring 10 is an industrial helical spring made of spring steel, generating torque or rotational force through elastic deformation. Standard parts used in this application can be directly purchased from the market, while irregularly shaped parts can be customized according to the instructions and drawings. The specific connection methods for each part all employ existing mature methods such as bolt connections, riveting connections, welding, and other conventional techniques. Mechanical components and equipment all use conventional models from the prior art, and therefore will not be described in detail. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0020] Reference Figure 1 , Figure 6 , Figure 7 A placement rack 17 is fixedly installed on the lower end of the inner wall of the housing 1. A funnel 14 is slidably installed inside the placement rack 17. A mesh 15 is fixedly installed on the upper end face of the placement rack 17 by two bolts. A top cover 4 is hinged to the upper end face of the housing 1 by a pin. Semicircular grooves 5 are opened on the upper end face of the front end of the housing 1 and the lower end face of the front end of the top cover 4. Magnetic strips 16 are fixedly installed on the inner top surface of the top cover 4 and the upper end face of the housing 1. The two magnetic strips 16 are magnetically attracted to each other. The lower end of the funnel 14 is slidably installed between the first support 6 and the second support 7.

[0021] Specifically, the placement rack 17 prevents the funnel 14 from being blocked, and the mesh 15 is secured with bolts. The funnel 14 guides pollen into the self-sealing bag. The mesh 15 intercepts the corn florets. The top cover 4 prevents pollen from being blown away by the wind when the device is shaken. The two semi-circular grooves 5 hold the corn stalks in place. The two magnetic strips 16 prevent the top cover 4 from opening on its own.

[0022] Reference Figure 1 — Figure 5 Two sliding rods 8 are fixedly installed on the inner walls of the front and rear ends of the fixed shell 2, near the inner walls on both sides. A rotating shaft 9 is rotatably installed on one side of the inner wall of the fixed shell 2, located at the lower end of the sliding rod 8, via a bearing. A gear 11 is fixedly connected to the other end of the rotating shaft 9. A torsion spring 10 is sleeved around the rotating shaft 9. Slider blocks 12 are fixedly installed at the rear corners of the upper end faces on both sides of the outer wall of the first bracket 6 and at the front ends of the upper end faces on both sides of the outer wall of the second bracket 7. A rack 13 is fixedly installed in the middle of one side of the outer wall of the first bracket 6 and the second bracket 7. A push rod 3 is fixedly installed at the front end of the lower rack 13. The fixed shell 2 is fixedly installed on the lower end face of the shell 1. The four sliders 12 are slidably installed around the four sliding rods 8 respectively. The first bracket 6 and the second bracket 7 are slidably installed in the middle of the four sliding rods 8. The two racks 13 are meshed with the gear 11. One end of the torsion spring 10 is fixedly connected to one side of the inner wall of the fixed shell 2, and the other end of the torsion spring 10 is fixedly connected to one end of the outer wall of the gear 11. The push rod 3 passes through the inner wall of the front end of the fixed shell 2 and is slidably installed at the front end of the fixed shell 2.

[0023] Specifically, push rod 3 can move rack 13, simultaneously compressing torsion spring 10. The two racks 13 mesh with gear 11, causing the first bracket 6 and the second bracket 7 to move synchronously. Four sliding rods 8 are respectively connected to four sliders 12, restricting the movement of the first bracket 6 and the second bracket 7 to only forward and backward. The torsion spring 10 causes the two racks 13 to move forward and backward respectively. The first bracket 6 and the second bracket 7 can then be used to widen the opening of the self-sealing bag.

[0024] Working principle: When using this device, first press the push rod 3 to bring the first support 6 and the second support 7 closer together. Then, place the self-sealing bag opening over the first support 6 and the second support 7, and then release the push rod 3. Open the top cover 4, place the funnel 14 inside the placement frame 17, and fix the strainer 15 to the upper end of the placement frame 17 with two bolts. Place the corn tassels inside the shell 1 and the corn stalks inside the semi-circular groove 5. Then close the top cover 4 and gently shake the device to collect pollen into the self-sealing bag. Simultaneously, the strainer 15 can intercept the corn florets.
