Description

Technical Field

[0001] The utility model relates to the technical field of wheat breeding, in particular to a seed selection device for wheat breeding. Background Art

[0002] Wheat is a general term for plants of the genus Triticum, with common wheat as its representative species. It belongs to the grass family and is a cereal crop widely cultivated around the world. Wheat caryopsis is one of the staple foods of mankind. The quality of wheat seeds directly affects wheat yield, so wheat seed selection is particularly important. Varieties should be selected according to local natural and cultivation conditions, ensuring that good varieties are matched with good methods, and that good varieties and good methods are promoted together. The most commonly used seed selection method is salt water seed selection, which involves placing seeds in a certain concentration of salt water and using buoyancy to separate good seeds from bad seeds. Because salt water has greater buoyancy than fresh water, it can float some underdeveloped seeds.

[0003] In the prior art, wheat cannot be directly stirred during salt water seed selection. Only using the flow of salt water to drive the wheat cannot make all the wheat roll, which may cause impurities to remain in the wheat and reduce the quality of seed selection. In response to the above problem, the document with application number: 202223338834.2 discloses a wheat breeding and selection device, which includes a water tank, a filter cartridge and a cover plate. The surface of the water tank is fixedly connected to a connecting pipe; a fixed block is fixedly connected to the surface of the water tank, and a rotating motor is provided above the fixed block. The output shaft of the rotating motor is fixedly connected to a connecting column, and the upper end of the connecting column is fixedly connected to a rotating plate 1. The surface of the rotating plate 1 is provided with a driving component for vertical movement and rotation of the filter cartridge;

[0004] However, after reading the above patent documents, the following problems were found: when in use, the filter cartridge needs to be removed from the water tank before the filtered wheat breeding can be taken out of the filter cartridge. This has the disadvantages of complicated operation steps, time-consuming and labor-intensive, and it is inconvenient to clean the impurities filtered out of the brine, which affects the screening of wheat breeding. There is room for improvement. Utility Model Content

[0041] First, the threaded rod 6 is driven by the motor 2 12 to rotate on the circular plate and the horizontal plate 4, and is threadedly driven with the screening plate 1 7 so that the screening plate 1 7 slides upward on the wheat selection box 3 and the rotating shaft 5, and the screening plate 1 7 moves to above the feed pipe on the wheat selection box 3, and then, the wheat seeds are transported into the wheat selection box 3 through the action of the feed pipe.

[0042] Then, the bevel gear 1 is driven by the motor 11 to rotate and mesh with the bevel gear 2 for transmission. At the same time, the bevel gear 2 drives the rotating shaft 5 to rotate on the circular plate and the horizontal plate 4. At the same time, the rotating shaft 5 drives multiple stirring blades to rotate synchronously, thereby achieving the purpose of stirring the wheat in the brine, and then the wheat in the wheat selection box 3 is completely rolled up. At the same time, through the action of the multiple sieve holes on the screening plate 1 7 and the screening plate 2 8 and the buoyancy of the brine, the impurities and inferior wheat in the wheat breeding can be filtered out. At the same time, the filtered impurities and inferior wheat breeding float on the upper surface of the brine through the buoyancy of the brine, thereby achieving the effect of screening and filtering the wheat breeding, thereby improving the quality of wheat breeding and selection;

[0043] Afterwards, the waterproof motor 9 drives the gear 2 to rotate and mesh with the gear ring 2 for transmission. At the same time, the gear ring 2 drives the screening plate 2 8 to rotate a certain angle within the control of the screening plate 1 7, and makes the screening plate 1 7 and the multiple sieve holes on the screening plate 2 8 misaligned, and makes the multiple sieve holes on the screening plate 2 8 correspond to the multiple through holes on the screening plate 1 7, so as to prevent impurities and inferior wheat from moving to the bottom of the screening plate 1 7, thereby achieving the effect of separating impurities and inferior wheat.

[0044] Afterwards, the solenoid valve on the discharge pipe at the bottom of the wheat selection box 3 is opened, and the motor four 21 is started. The corresponding transmission roller 19 is driven by the motor four 21 to rotate on the box body 18. At the same time, the two transmission rollers 19 are synchronously rotated on the box body 18 through the transmission of the mesh belt 20. At the same time, the mesh belt 20 is rotated in the box body 18 by the action of the two transmission rollers 19. In this process, the brine in the wheat selection box 3 is discharged from the discharge pipe together with the screened wheat seeds. At this time, the mesh belt 20 can be used to filter the wheat seeds in the brine. At the same time, the rotation of the mesh belt 20 can achieve the purpose of transporting the wheat seeds to the discharge port on the box body 18. At the same time, the guide plate in the discharge port can be used to guide the screened wheat seeds, which is convenient for collection. At the same time, the brine is stored in the box body 18, thereby achieving the effect of automatic unloading of the screened wheat seeds.

[0045] Afterwards, the threaded rod 6 is driven by the motor 2 12 to rotate on the circular plate and the horizontal plate 4, and is threadedly driven with the screening plate 1 7 so that the screening plate 1 7 slides upward on the wheat seed selection box 3 and the rotating shaft 5, and the screening plate 1 7 is moved to the top of the feeding pipe on the wheat seed selection box 3, and the top of the screening plate 1 7 contacts the two brush plates 17 and the screening plate 1 7 corresponds to the impurity discharge port on the wheat seed selection box 3, then, the gear 14 is driven by the motor 3 13 to rotate and transmit the transmission to the gear ring 15, and the gear ring 15 brings The movable circular tube 16 rotates on the wheat seed selection box 3, and at the same time, the circular tube 16 drives the two brush plates 17 to rotate synchronously, and the two brush plates 17 clean the impurities and inferior wheat seeds on the screening plate 7. In this process, the centrifugal force generated by the rotation of the two brush plates 17 makes the impurities and inferior wheat seeds cleaned by the two brush plates 17 move toward the screening plate 7. Afterwards, the impurities and inferior wheat seeds are discharged from the impurity discharge port under the action of the two brush plates 17, thereby achieving the effect of cleaning the impurities and inferior wheat seeds.

[0046] Finally, start the liquid pump 22 and close the solenoid valve on the discharge pipe at the bottom of the wheat seed selection box 3. The brine stored in the box body 18 is transported to the wheat seed selection box 3 through the drive of the liquid pump 22 and the action of the delivery pipe 23. At the same time, the feed pipe on the wheat seed selection box 3 transports wheat breeding into the wheat seed selection box 3, and then repeat the above operation.

[0047] The technical progress achieved by the present invention compared with the existing technology is that through the cooperation of various components, it can not only achieve the effect of cleaning impurities in wheat breeding, thereby improving the quality of wheat breeding, but also achieve the effect of quickly unloading the wheat breeding after screening, thereby improving efficiency, and can achieve the effect of cleaning filtered impurities and defective wheat breeding, thereby improving convenience and higher practicality.
