Description

Technical Field

[0001] The invention relates to the technical field of flower mutation breeding, in particular to a device and method for flower seed breeding using ionizing radiation mutation. Background Art

[0002] Mutation breeding involves using physical or chemical factors to induce genetic variation in plants. Individual plants or individuals that meet specific requirements are then selected from the mutant population to develop new varieties or germplasm. It is a modern breeding technique that has evolved after selective breeding and hybrid breeding. Physical mutagenesis primarily involves radiation, using physical agents such as alpha, beta, gamma, X-rays, ultraviolet radiation, and microwave particle radiation to induce variation. Currently used radiation breeding methods include space-based and field-based. Space-based breeding involves exposing seeds to space radiation to induce variation. Field-based breeding involves placing a radiation source in a field to induce variation. Space-based breeding is expensive, and field-based breeding has strict restrictions, such as site selection, personnel access management, and radiation shielding. These issues limit the scope of radiation breeding. Therefore, people will set up an ionizing radiation mutagenesis breeding box with a shielding effect, which not only facilitates the mutagenesis breeding of flower seeds, but also reduces costs.

[0003] For example, the Chinese patent authorization announcement number CN 217284380 U discloses a mutation breeding machine for high-quality seed selection. The machine, through the provided drive motor, rotating frame, servo motor, rotating roller and rotating blades, can fully drive the seeds to rotate and flip relative to each other, avoiding the accumulation of a large number of seeds and affecting the irradiation effect of ultraviolet rays. The machine has a simple structure, is easy to operate, and is convenient and stable to use, with high practical value.

[0004] However, the above patent still has some problems during use. For example, during use, the operator is required to open the breeding box and pull out the rotating rack inside the breeding box to load and unload the flower seeds. Ionizing radiation is harmful to the human body. Sometimes the operator forgets to turn off the ionizing radiation source and opens the breeding box, and a large amount of radiation source is emitted, which causes great harm to people.

After releasing the push handle, the discharge pipe moves upward under the action of the tension spring, so that the conical head at the upper end of the discharge pipe is located in the annular guide groove in the middle of the mutagenesis box. Slowly rotate the mutagenesis box. When the discharge port on the mutagenesis box rotates to the conical head, the conical head extends into the discharge port under the action of the tension spring.

Ionizing radiation can enter the mutagenesis box 2 through the radiation holes 26 to mutate the flower seeds, and the flower seeds after the mutagenesis treatment are discharged through the discharge port 28.

[0042] In a preferred embodiment, a conical head 30 is provided at the top of the discharge pipe 13, and a plurality of leakage ports 31 are provided at the edge of the conical head 30, one end of the leakage port 31 is connected to the discharge pipe 13, one end of the discharge pipe 13 passes through the bottom side wall of the breeding box 1, and is fixedly connected to a push handle 32 provided at the outer end of the breeding box 1, the upper end of the push handle 32 is fixedly provided with a tension spring 33, the upper end of the tension spring 33 is fixedly provided on the bottom side wall of the breeding box 1, and a through hole connected to the discharge pipe 13 is opened in the middle position of the push handle 32. After the discharge pipe 13 loses its restriction, it moves upward under the action of the tension spring 33, so that the conical head 30 is located in the annular guide groove 27 in the mutagenesis box 2. As the mutagenesis box 2 slowly rotates, when the discharge port 28 rotates to the conical head 30, the conical head 30 can enter the discharge port 28 and pierce the rubber plug 29, so that the flower seeds are discharged.

[0043] In a preferred embodiment, a limiting protrusion 34 is provided at the connection between the discharge pipe 13 and the bottom side wall of the breeding box 1, a guide groove 35 is provided at the bottom side wall of the breeding box 1, one side of the guide groove 35 is connected to the limiting groove 36, a plug hole 37 is provided on the limiting protrusion 34, and a plug rod 38 is provided on the bottom side wall of the breeding box 1.

[0044] In a preferred embodiment, the feed pipe 14 is arranged at an angle, and the inclined end of the feed pipe 14 is connected to the mutagenesis box 2 through a rotary joint 39. A feed hopper 40 is provided on one side of the feed pipe 14 located at the outer end of the breeding box 1, and a shielding cover is provided at the feed hopper 40.

[0045] In a preferred embodiment, a downward pressure ball 41 is provided on the upper part of the feed pipe 14, and a lifting plate 43 is fixedly connected to the upper part of the downward pressure ball 41 through a connecting rod 42. A compression spring 44 is fixedly provided on the upper end of the lifting plate 43, and the bottom end of the lifting plate 43 is inclined. An extrusion rod 45 is fixedly provided on one side of the connecting shaft 10. When the extrusion rod 45 follows the connecting shaft 10 to rotate to the lifting plate 43, the extrusion rod 45 contacts the lifting plate 43. As the extrusion rod 45 continues to rotate, the extrusion rod 45 can lift the lifting plate 43, so that the lifting plate 43 drives the downward pressure ball 41 to rise through the connecting rod 42. When the extrusion rod 45 is separated from the lifting plate 43, the lifting plate 43 moves downward under the action of the compression spring 44, so that the downward pressure ball 41 hits the feed pipe 14 downward, so that the feeding effect is better.

[0046] A method for using a device for inducing flower seed breeding by ionizing radiation, comprising the following steps:

[0047] S1, introduce the flower seeds to be processed into the mutagenesis box 2 through the feed pipe 14, turn on the α-ray emitter 4, β-ray emitter 5, Y-ray emitter 6, X-ray emitter 7, ultraviolet radiator 8 and microwave particle radiator 9 on the mounting plate 3 as needed, turn on the drive motor 12, and the drive motor 12 drives the mutagenesis box 2 to rotate. When the mutagenesis box 2 rotates, it can drive the mounting plate 3 to rotate through the transmission mechanism;

[0048] S2, when feeding in S1, turn on the drive motor 12. When the drive motor 12 is working, it can drive the connecting shaft 10 to rotate through the transmission mechanism. When the connecting shaft 10 rotates, it can drive the extrusion rod 45 to rotate. When the extrusion rod 45 rotates to the lifting plate 43, since the bottom end of the lifting plate 43 is inclined, the extrusion rod 45 can lift the lifting rod 43, thereby causing the pressing ball 41 to rise. When the extrusion rod 45 is separated from the lifting plate 43, the lifting plate 43 moves downward under the action of the compression spring 44, causing the pressing ball 41 to move downward and hit the feeding tube 14, so that the feeding effect is better.

[0049] S3, the radiation generated by the α-ray emitter 4, the β-ray emitter 5, the γ-ray emitter 6, the X-ray emitter 7, the ultraviolet radiator 8 and the microwave particle radiator 9 when in operation enters the mutagenesis box 2 through the radiation hole 26 on the mutagenesis box 2, and performs a mutagenesis treatment on the flower seeds in the mutagenesis box 2;

[0050] S4. After the mutagenesis treatment is completed, pull out the connecting rod 38, and then rotate the push handle 32 so that the limiting protrusion 34 moves to the guide groove 35. After releasing the push handle 32, the discharge pipe 13 moves upward under the action of the tension spring 33, so that the conical head 30 at the upper end of the discharge pipe 13 is located in the annular guide groove 27 in the middle of the mutagenesis box 2. Slowly rotate the mutagenesis box 2. When the discharge port 28 on the mutagenesis box 2 rotates to the conical head 30, the conical head 30 extends into the discharge port 28 under the action of the tension spring 33. The conical head 30 will pierce the rubber plug 29, and the flower seeds inside the mutagenesis box 2 are discharged through the leakage port 31, the discharge pipe 13 and the push handle 32, thereby realizing ionizing radiation mutagenesis of the flower seeds.

[0051] The working principle of the present invention is as follows: the flower seeds to be processed are introduced into the mutagenesis box 2 through the feed pipe 14. After all the flower seeds are introduced, the shielding cover at the feed hopper 40 is closed, and the α-ray emitter 4, β-ray emitter 5, Y-ray emitter 6, X-ray emitter 7, ultraviolet radiator 8 and microwave particle radiator 9 on the mounting plate 3 are selectively opened as needed, and then the drive motor 12 is turned on. The drive motor 12 drives the mutagenesis box 2 to rotate. When the mutagenesis box 2 rotates, it can drive the connecting shaft 10 to rotate through the first bevel gear 15, the second bevel gear 16, the connecting shaft 17, the first sprocket 18, the chain 19 and the second sprocket 20. When the connecting shaft 10 rotates, it can drive the mounting plate 3 to rotate. The disk 3 rotates, causing the mutagenesis box 2 and the various ionizing radiation sources on the mounting disk 3 to rotate synchronously, which has a better mutagenesis effect on the flower seeds. When the connecting shaft 10 rotates, it can also drive the squeezing rod 45 to rotate. When the squeezing rod 45 rotates to the lifting plate 43, since the bottom end of the lifting plate 43 is inclined, the squeezing rod 45 can drive the lifting plate 43 to move upward to squeeze the compression spring 44, so that the pressing ball 41 is away from the feeding pipe 14. When the squeezing rod 45 is separated from the lifting plate 43, the lifting plate 43 moves downward under the action of the compression spring 44 and gravity, so that the pressing ball 41 moves downward rapidly and hits the feeding pipe 14, so that all the flower seeds in the feeding pipe 14 enter the mutagenesis box 2;

[0052] After the mutagenesis treatment of the flower seeds is completed, the driving motor 12 is turned off, the connecting rod 38 is rotated and pulled out from the side wall of the breeding box 1, and the push handle 32 is rotated to make the limiting protrusion 34 on the discharge pipe 13 rotate from the limiting groove 36 to the guide groove 35. After releasing the push handle 32, the discharge pipe 13 moves upward under the action of the compression spring and tension spring 33, so that the conical head 30 at the upper end of the discharge pipe 13 contacts the annular guide groove 27 in the middle position of the mutagenesis box 2. Then the driving motor 12 is turned on to make the mutagenesis box 2 rotate slowly. When the conical structure on the mutagenesis box 2 rotates to the bottom, the conical head 30 can be inserted into the discharge port 28. The driving motor 12 is turned off. After the conical head 30 enters the discharge port, it pierces the rubber plug 29 and enters the interior of the mutagenesis box 2. The flower seeds inside the mutagenesis box 2 enter the discharge pipe 13 through the conical head 30 and are discharged through the through hole in the middle of the push handle 32, thereby realizing the export of the flower seeds.

[0053] After all the flower seeds are exported, the conical head 30 is pulled out from the discharge port 28. After the conical head 30 is pulled out to a certain distance, the discharge pipe 13 is rotated so that the limiting protrusion 34 on the discharge pipe 13 is rotated from the guide groove 35 to the limiting groove 36, and then the connecting rod 38 is inserted into the side wall of the breeding box 1 so that the connecting rod 38 is inserted into the connecting hole 37 of the limiting protrusion 34, and then the connecting rod 38 is rotated so that the threaded part at the end of the connecting rod 38 is docked with the threaded groove on the side wall of the limiting groove 36 to achieve the limitation of the discharge pipe 13. At this time, the conical head 30 is not in contact with the mutagenesis box 2.

[0054] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.

10. A method for using a device for inducing flower seed breeding by ionizing radiation, characterized in that: According to the device for flower seed breeding using ionizing radiation mutagenesis as described in any one of claims 1 to 9, the steps are as follows: S1, introducing the flower seeds to be processed into the mutagenesis box (2) through the feeding pipe (14), turning on the α-ray emitter (4), β-ray emitter (5), γ-ray emitter (6), X-ray emitter (7), ultraviolet radiator (8) and microwave particle radiator (9) on the mounting plate (3) as needed, turning on the driving motor (12), and the driving motor (12) drives the mutagenesis box (2) to rotate, and when the mutagenesis box (2) rotates, it can drive the mounting plate (3) to rotate through the transmission mechanism; S2, when feeding in S1, the driving motor (12) is turned on. When the driving motor (12) is working, it can drive the connecting shaft (10) to rotate through the transmission mechanism. When the connecting shaft (10) rotates, it can drive the extrusion rod (45) to rotate. When the extrusion rod (45) rotates to the lifting plate (43), since the bottom end of the lifting plate (43) is inclined, the extrusion rod (45) can lift the lifting rod (43), thereby causing the pressing ball (41) to rise. When the extrusion rod (45) is separated from the lifting plate (43), the lifting plate (43) moves downward under the action of the compression spring (44), causing the pressing ball (41) to move downward and hit the feeding pipe (14), so that the feeding effect is better; S3, the radiation generated by the α-ray emitter (4), the β-ray emitter (5), the γ-ray emitter (6), the X-ray emitter (7), the ultraviolet radiator (8) and the microwave particle radiator (9) when in operation enters the mutagenesis box (2) through the radiation hole (26) on the mutagenesis box (2), and performs a mutagenesis treatment on the flower seeds in the mutagenesis box (2); S4, after the mutagenesis treatment is completed, the plug rod (38) is pulled out, and then the push handle (32) is rotated so that the limiting protrusion (34) moves to the guide groove (35). After the push handle (32) is released, the discharge pipe (13) moves upward under the action of the tension spring (33), so that the conical head (30) at the upper end of the discharge pipe (13) is located in the annular guide groove (27) in the middle of the mutagenesis box (2). The mutagenesis box (2) is slowly rotated. When the discharge port (28) on the mutagenesis box (2) is rotated to the conical head (30), the conical head (30) extends into the discharge port (28) under the action of the tension spring (33). The conical head (30) will pierce the rubber plug (29), and the flower seeds inside the mutagenesis box (2) are discharged through the leakage port (31), the discharge pipe (13) and the push handle (32), thereby realizing the ionizing radiation mutagenesis of the flower seeds.
