Description

Technical Field

[0001] This invention relates to the field of maize breeding technology, specifically to a powder extractor for maize breeding. Background Technology

[0002] In the process of corn cultivation, due to abnormal natural factors or the influence of soil, cultivation techniques, and human factors, the phenomenon of flowering mismatch often occurs, especially the phenomenon of late male parent. Sometimes the flowering mismatch is so severe that conventional control and promotion measures are no longer effective. To address this, we have tried to use the technique of "external male extraction - pollen in vitro culture - artificial pollination" to provide a new way to solve the problem of severe flowering mismatch under abnormal conditions.

[0003] Currently, pollen collection from corn tassels is typically done manually in cornfields. However, because corn pollen is located on the tassels at the top of the corn stalks, and the stalks are quite tall, manual collection requires bending the corn stalks, covering the tassels with a bag, and shaking the stalks to allow the anthers connected by the silks and the pollen inside the anthers to fall into the bag. However, the corn stalks are close together in the field, and the bent tassels inevitably collide with other stalks. The pollen on the tassels scatters everywhere due to the shaking and collisions, wasting pollen, making the collection time-consuming and laborious, and increasing the risk of breaking the stalks and causing damage.

[0004] Therefore, a new pollen extractor for maize breeding needs to be designed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a corn pollen extractor for corn breeding, the specific solution of which is as follows:

[0021] The technical solution of the present invention will be further described in detail below through specific embodiments. Example

[0022] like Figure 1-6As shown, this invention provides a corn pollen extractor for corn breeding, comprising a cover body 1 and a cover body 2. The tops of the cover body 1 and cover body 2 are respectively provided with a top plate 3 and a top plate 4. The top plate 3 has a semi-circular notch, and the top plate 4 includes a semi-circular plate corresponding to the semi-circular notch. The bottoms of the cover body 1 and cover body 2 are semi-circular openings facing each other. The tops of the top plate 3 and top plate 4 are provided with multiple parallel elastic telescopic rods 17. Each elastic telescopic rod... The two ends of 17 are fixedly connected to top plate 3 and top plate 4 respectively; a pneumatic assembly 10 is provided on top plate 4, the pneumatic assembly 10 includes a cylinder 10-1, the side of the cylinder 10-1 is provided with an air inlet 10-2 and an air outlet 10-3, a piston 10-4 is slidably provided inside the cylinder 10-1, and an elastic rod 10-7 is provided on the top of the inner side of the cylinder 10-1, the telescopic end of the elastic rod 10-7 is connected to the piston 10-4, and the piston 10-4 is provided with a through-hole The top of the cylinder 10-1 has a guide rod 10-5, on which a support rod 10-6 is provided; the top plate 3 has a fixing ear 18, which is connected to one end of the pull rope 13; the top plate 4 has a rotating frame, on which a fixed pulley is rotatably mounted, and the other end of the pull rope 13 passes over the fixed pulley and is connected to the support rod 10-6; the top plate 4 has a powder-grinding component 9 associated with the pneumatic component 10; the bottom of the cover 2 has a discharge port 5, which is connected to the inlet of the induced draft fan 6; the outlet of the induced draft fan 6 is connected to a collection device 8 on the top plate 4 through an exhaust pipe 7, and the collection device 8 is associated with the pneumatic component 10 and the powder-grinding component 9; the side of the cover 2 has a hinge frame 14, on which a hand handle 15 is provided, and a handle 16 is provided on the hand handle 15, which has a controller 23 for the induced draft fan 6.

[0023] The aforementioned pollination assembly 9 is used to remove the pollen-covered anthers from the corn stalks to facilitate subsequent pollen collection. It includes a cylindrical shell 9-1 fixed to the top plate 4. An air inlet 9-2 is located on the side of the shell 9-1, its orientation offset from the axis of the shell 9-1. The air inlet 9-2 is connected to the exhaust port 10-3 via an exhaust pipe 12. An air outlet 9-3 is located at the top of the shell 9-1. A rotating pipe 9-4 is rotatably mounted through the axis of the shell 9-1. The rotating tube 9-4 penetrates the top plate 2 4. The top of the rotating tube 9-4 is closed. The rotating tube 9-4 located inside the shell 9-1 has multiple through holes 9-6 and multiple fan blades 9-5. The rotating tube 9-4 located below the top plate 2 4 has multiple support rods 9-9. The support rods 9-9 have a base 9-10. The base 9-10 has multiple comb teeth 9-11 for scraping the tassels at the top of the corn stalks and cleaning brushes 9-12 for cleaning the inner walls of the cover 1 and the cover 2.

[0024] The aforementioned collection device 8 is used to collect anthers and pollen that have fallen from the male spike. It includes a shell 8-1, inside which is a partition 8-3. A cyclone separator 8-4 is installed through the partition 8-3. Inside the shell 8-1, below the cyclone separator 8-4, is an inclined screen 8-5. A slag discharge port 8-6 is provided on the side wall of the shell 8-1 corresponding to the lowest point of the screen 8-5. A discharge port 8-7 is provided at the bottom of the shell 8-1. A pull-out filter assembly 8-8 is provided inside the shell 8-1 above the cyclone separator 8-4. An exhaust port 8-2 is provided at the top of the shell 8-1. The airflow inlet of the cyclone separator 8-4 is connected to the exhaust pipe 7.

[0025] Considering that the anthers and pollen entering the collecting device 8 may not be separated and may fall onto the sieve 8-5, a striking mechanism is provided on the outside of the outer shell 8-1 to facilitate the sieving of the two. The striking mechanism includes a support frame 8-9 fixed to the outside of the outer shell 8-1, a support shaft 8-10 fixed on the support frame 8-9, a striking plate 8-11 rotatably mounted on the support shaft 8-10, and a torsion spring 8-12 on the support shaft 8-10 to force one end of the striking plate 8-11 to fit against the outer shell 8-1; the rotating tube 9-4 is provided with a gear 9-8 for the striking plate 8-11.

[0026] After the airflow discharged through exhaust pipe 11 enters the air inlet 10-2 in the pneumatic assembly 10, piston 10-4 gradually rises, and guide rod also rises accordingly. This causes pull rope 13 to pull top plate 3 towards top plate 4. It is important to note that top plates 3 and 4 must not come into contact before the airflow exits through exhaust pipe 10-3; otherwise, guide rod cannot continue to rise, piston 10-4 cannot rise, and airflow cannot exit through exhaust pipe 10-3, preventing the powder-grinding assembly 9 from operating. However, if the airflow can exit through exhaust pipe 10-3 before top plates 3 and 4 come into contact, and piston 10-4... If the air pressure at the bottom of 0-4 is not high enough, the piston 10-4 will not be able to continue to rise. At this time, since the pollen-beating component 9 is operating normally, the anthers and pollen that are knocked down may fall from the gap between the first cover 1 and the second cover 2, causing the anthers and pollen to not fall normally to the discharge port and enter the collection device 8 with the airflow. Therefore, a pre-sealing edge 20 is provided on the inner side of the two sides of the first cover 1 opposite the second cover 2. When the airflow can just be discharged from the exhaust port 10-3 so that the pollen-beating component 9 is operating, the pre-sealing edge 20 can enter the second cover 2, ensuring that the anthers and pollen that fall from the tassel can fall smoothly to the vicinity of the discharge port and be collected.

[0027] It should be noted that, for ease of use of the device, the aforementioned handheld lever 15 has a hollow structure, and a battery that powers the entire device is installed inside the handheld lever 15.

[0028] To ensure operator comfort, the top of the hand lever 15 is hinged to the hinge frame 14, and the hinge frame 14 is provided with multiple positioning holes 21. The top of the rotating rod is also provided with through holes 9-6 corresponding to the positioning holes 21. The top of the rotating rod is fixed to the hinge frame 14 by bolts and nuts 22 corresponding to the positioning holes 21.

[0029] The specific working principle of this invention is as follows: When pollen needs to be collected, the male spike is first placed between cover 1 and cover 2. Then, the blower 6 is started. Under the action of the blower 6, the airflow enters the cyclone separator 8-4 from the exhaust pipe 7. Then, the airflow is discharged from the exhaust port 8-2 and enters the outer shell 8-1 through the exhaust pipe 11. The airflow pushes the piston 10-4 to move upward, and the guide rod moves upward accordingly. The pull rope 13 pulls the top plate 3 closer to the top plate 4. When the pre-sealing edge 20 on cover 1 enters cover 2, the airflow begins to be discharged from the exhaust port 10-3 and enters the outer shell 8-1 of the pollination component 9. The airflow blows on the fan blades 9-5 inside the outer shell 8-1, causing the rotating tube 9-4 to rotate. The multiple comb teeth 9-11 beat or comb the male spike, causing the anthers and pollen to fall off. The airflow inside the outer shell 8-1 enters the rotating tube 9-4 through the through hole 9-6 and exits from the bottom of the rotating tube 9-4, blowing onto the male spike. The fallen anthers and pollen enter the pollen discharge port under the action of the airflow, and then enter the collection device 8 through the blower 6 and the exhaust pipe 7, and fall onto the screen 8-5 inside the collection device 8. At this time, it should be noted that because the actuating gear 9-8 is constantly actuating the beating plate 8-11, the pollen on the screen 8-5 is shaken off and can be discharged through the discharge port 8-7, while the anthers and other impurities remain on the screen 8-5 and can be discharged through the slag discharge port 8-6.

[0030] After the pollen collection of a certain male ear is completed, the blower 6 is turned off. Under the action of the elastic rod 10-7, the piston 10-4 moves downward. Under the action of the elastic telescopic rod 17, the top plate 2 4 moves away from the top plate 1 3.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
