Description

Technical Field

[0001] The present invention relates to the technical field of seed screening, and in particular to a device and method for screening and processing superior seeds for rice cultivation. Background Art

[0002] Screening of superior rice seeds is an important step in ensuring high yield, high quality and stress resistance. Through seed selection, we can create favorable conditions for high yield and high quality of rice, while promoting the sustainable development and progress of agriculture.

[0003] The first step in screening for superior rice varieties is to remove inferior seeds that are deformed, damaged, shriveled, moldy, or worm-eaten, and retain full grains. The commonly used method is to use the concentration and density of water or salt water to make the superior rice varieties with higher density sink to the bottom of the water, while the inferior varieties with lower density remain on the water surface, thus separating the superior and inferior rice varieties into layers. The inferior varieties on the upper layer are fished out to achieve the screening of high-quality rice seeds.

[0004] The existing seed screening and processing device is not convenient for separating the bad seeds in the upper layer after stratification by the density of water or salt water. Manual salvage is not only time-consuming and labor-intensive, but also easily stirs the middle layer seeds during the salvage process, destroying the stability of the stratification and easily causing missed screening or wrong screening. Based on this, a device and method for screening and processing high-quality seeds for rice cultivation are proposed. Summary of the Invention

[0015] A method for screening and processing superior rice seeds for rice cultivation comprises the following steps:

[0016] Step 1: First, add clean water or salt water of appropriate concentration into the box, add the rice seeds to be screened into the box, start the stirring component to stir the added rice seeds, accelerate the migration of shriveled and damaged seeds to the liquid surface, and shorten the screening time;

[0017] Step 2: After the stirring is completed, the mixture is allowed to stand for stratification. After the stratification is completed, the first threaded rod is started to rotate so that the movable seat drives the scraping assembly below to move toward the through groove.

[0020] (1) The present invention drives the rotating rod and the first bevel gears at both ends of the rotating rod to rotate through the rotation of the dual-axis motor, the first bevel gear engages with the second bevel gear to rotate, and the second bevel gear drives the first threaded rod to rotate, so that the moving seat on the first threaded rod drives the scraping assembly below to scrape the shriveled and damaged seeds on the upper layer of the box toward the through groove. While scraping, the third bevel gear at the other end of the first threaded rod engages with the fourth bevel gear to rotate, and the fourth bevel gear drives the second threaded rod to rotate, so that the sealing plate moves into the accommodating groove, gradually releasing the seal on the through groove, so that the shriveled and damaged seeds on the upper layer of the box flow out of the through groove with the water flow, and are separated from the full rice seeds at the bottom of the box.

[0021] (2) In the present invention, while the moving seat drives the scraping assembly to move toward the through groove, the gear on the third threaded rod in the scraping assembly continuously engages with the rack during the movement, so that the gear drives the third threaded rod to rotate. The rotation of the threaded rod causes the threaded tube to drive the scraper to move downward, so that the scraper adapts to the continuously decreasing liquid level, so that the scraper is always below the liquid level, ensuring the scraping of the upper layer of shriveled and damaged seeds, and preventing the scraper from being separated from the upper liquid surface when the liquid drives the upper layer of shriveled and damaged seeds to move toward the through groove, resulting in the leakage of the shriveled and damaged seeds.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] like Figure 1-12As shown, a superior seed screening and processing device for rice cultivation comprises a box body 1, a stirring assembly is provided at the bottom of the box body 1, a discharge pipe 2 is fixedly provided at the bottom of the box body 1, a solenoid valve 3 is fixed on the discharge pipe 2, two first threaded rods 4 are symmetrically connected to the top of the box body 1 for rotation, an outer wall of one side of the box body 1 is provided with a driving mechanism for synchronous rotation of the two first threaded rods 4, a movable seat 5 is threadedly connected to the first threaded rod 4, a scraping assembly is provided at the bottom of the movable seat 5, a driving assembly for moving the scraping assembly up and down is provided on the inner wall of the box body 1 near the first threaded rod 4, a through groove 6 is provided on one side wall of the box body 1, the through groove 6 is provided on a side wall of the box body 1 perpendicular to the axis of the first threaded rod 4, and the through groove 6 is provided on the upper side of the side wall of the box body 1, a receiving groove 7 is provided at the bottom of the through groove 6, a sealing plate 8 is slidably provided in the receiving groove 7, the sealing plate 8 is used to seal the through groove 6, and a lifting mechanism for moving the sealing plate 8 up and down is provided in the side wall of the box body 1.

[0037] The driving mechanism includes a dual-axis motor 9 fixedly arranged on the outer wall of the box body 1 away from the through groove 6. The output shaft of the dual-axis motor 9 is fixedly connected to a rotating rod 10. The end of the rotating rod 10 is fixedly sleeved with a first bevel gear 11. The end of the first threaded rod 4 close to the dual-axis motor 9 extends through the outside of the box body 1 and is fixedly sleeved with a second bevel gear 12. The second bevel gear 12 is meshed and connected with the first bevel gear 11.

[0038] The rotation of the dual-axis motor 24 drives the rotating rod 10 and the first bevel gears 11 at both ends to rotate, the first bevel gear 11 engages the second bevel gear 12 to rotate, and the second bevel gear 12 drives the first threaded rod 4 to rotate, so that the moving seat 5 on the first threaded rod 4 drives the scraping assembly below to move toward the through groove 6, scraping the shriveled and damaged seeds on the upper layer of the box body 1 toward the through groove 6.

[0039] The lifting mechanism includes two second threaded rods 13 rotatably connected to the top inner wall of the through slot 6 , the second threaded rods 13 correspond to the positions of the first threaded rod 4 , and the second threaded rods 13 are threadedly connected to the inner walls on both sides of the sealing plate 8 .

[0040] A driving groove 14 is provided on the inner wall of the box body 1 close to the through groove 6. One end of the first threaded rod 4 extends through the driving groove 14 and is fixedly sleeved with a third bevel gear 15. The top of the second threaded rod 13 extends through the driving groove 14 and is fixedly sleeved with a fourth bevel gear 16. The fourth bevel gear 16 is meshed and connected with the third bevel gear 15.

[0041] As the first threaded rod 4 rotates, the third bevel gear 15 at the other end is driven to rotate, and the third bevel gear 15 engages with the fourth bevel gear 16 to rotate. The fourth bevel gear 16 drives the second threaded rod 13 to rotate. The rotation of the second threaded rod 13 causes the sealing plate 8 threadedly connected thereto to move into the accommodating groove 7, gradually releasing the seal on the through groove 6. The shriveled and damaged seeds on the upper layer of the box body 1 flow out of the through groove 6 with the water flow and are separated from the plump rice seeds at the bottom of the box body 1.

[0042] The scraping assembly includes a third threaded rod 17, a threaded barrel 18 and a scraper 19. The top of the third threaded rod 17 is rotatably connected to the bottom of the movable seat 5 through a bearing. The threaded barrel 18 is fixed on both sides of the scraper 19. The third threaded rod 17 is threadedly connected to the threaded barrel 18.

[0043] The driving assembly includes a rack 20 and a gear 21. The rack 20 is fixed on the inner wall of the box body 1 close to the first threaded rod 4. The gear 21 is fixedly sleeved on the upper side of the third threaded rod 17. The gear 21 is meshed and connected with the rack 20.

[0044] While the moving seat 5 drives the scraping assembly to move toward the through groove 6, the gear 21 on the third threaded rod 17 in the scraping assembly continuously engages with the rack 20 during the movement, so that the gear 21 drives the third threaded rod 17 to rotate. The rotation of the threaded rod 17 causes the threaded cylinder 18 to drive the scraper 19 to move downward, so that the scraper 19 adapts to the continuously decreasing liquid level, so that the scraper 19 is always below the liquid level, ensuring the scraping of the upper layer of shriveled and damaged seeds, and avoiding the scraper 19 from being separated from the upper liquid surface due to the drop in the liquid level when the liquid drives the upper layer of shriveled and damaged seeds to move toward the through groove 6, resulting in the leakage of the shriveled and damaged seeds.

[0045] The stirring assembly includes a stirring shaft 22 rotatably connected to the inner wall at the bottom of the box body 1, a plurality of stirring blades 23 are evenly fixed on the stirring shaft 22, and a stirring motor 24 is fixed on the outer wall of the box body 1. One end of the stirring shaft 22 passes through the box body 1 and is fixedly connected to the output shaft of the stirring motor 24. The stirring motor 24 drives the stirring shaft 22 and the stirring blades 23 to rotate, stirring the rice seeds that need to be screened added to the box body 1, so that the seeds are fully in contact with the water or salt water in the box body 1, accelerating the migration of shriveled and damaged seeds to the liquid surface, and shortening the screening time.

[0046] A collecting box 25 is fixedly provided on the outer wall of one side of the box body 1 close to the through groove 6. The collecting box 25 is located below the through groove 6. A filter plate 26 is fixedly provided at the bottom of the collecting box 25. The dry, damaged and other inferior seeds on the upper layer of the box body 1 are discharged from the through groove 6 and fall into the collecting box 25 below for collection. The moisture is filtered out by the filter plate 26. A sealed box door is hinged on one side of the collecting box 25 to facilitate the removal of the collected dry, damaged and other inferior seeds.

[0047] The scraper 19 is evenly provided with a plurality of through holes 27. The size of the through holes 27 is smaller than the dried, damaged and low-quality rice seeds that need to be removed. By providing the through holes 27, some water or salt water is allowed to pass through the scraper 19 when the scraper 19 moves, thereby reducing the liquid resistance during scraping. On the one hand, the scraper 19 can run more smoothly, and on the other hand, the agitation of the water by the scraper 19 when moving is reduced.

[0048] A method for screening and processing superior rice seeds for rice cultivation comprises the following steps:

[0049] Step 1: First, add clean water or salt water of appropriate concentration into the box 1, add the rice seeds to be screened into the box 1, start the stirring component to stir the added rice seeds, accelerate the migration of shriveled and damaged seeds to the liquid surface, and shorten the screening time;

[0050] Ensure that the sealing plate 8 on the side wall of the box body 1 is in a state of sealing the through groove 6, and at the same time, the scraping assembly is on the side of the box body 1 away from the through groove 6, add an appropriate amount of clean water and salt water of appropriate concentration into the box body 1, add rice seeds that need to be screened, so that the liquid level is higher than the height of the through groove 6 in the box body 1, and the bottom of the scraping assembly is located below the liquid level, start the stirring motor 24 to drive the stirring shaft 22 and the stirring blade 23 to rotate, and stir the rice seeds that need to be screened added to the box body 1, so that the seeds are fully in contact with the water or salt water in the box body 1, accelerate the migration of shriveled and damaged seeds to the liquid surface, shorten the screening time, and quickly complete the stratification.

[0051] Step 2: After the stirring is completed, the mixture is allowed to stand and separate. After the separation is completed, the first threaded rod 4 is started to rotate so that the movable seat 5 drives the scraping assembly below to move toward the through groove 6. While the scraping assembly is scraping, the sealing plate 8 and the scraping assembly move downward synchronously, so that the dried and damaged seeds on the upper layer overflow from the through groove 6 and fall into the collection box 25 on one side;

[0052] After the stratification is completed by standing still, the dual-axis motor 24 is started to drive the rotating rod 10 and the first bevel gears 11 at both ends thereof to rotate. The first bevel gear 11 engages with the second bevel gear 12 to rotate, and the second bevel gear 12 drives the first threaded rod 4 to rotate, so that the moving seat 5 drives the scraper 19 below to move in the direction of the through groove 6, and the shriveled and damaged seeds on the upper layer of the box body 1 are scraped in the direction of the through groove 6. At the same time, the third bevel gear 15 at the other end of the first threaded rod 4 engages with the fourth bevel gear 16 to rotate, and the fourth bevel gear 16 drives the second threaded rod 13 to rotate, so that the seal The plate 8 moves into the accommodating groove 7, gradually releasing the seal on the through groove 6. At the same time, the gear 21 on the third threaded rod 17 below the moving seat 5 continuously engages with the rack 20 during the movement, so that the gear 21 drives the third threaded rod 17 to rotate, and the threaded cylinder 18 drives the scraper 19 to move downward, so that the dry and damaged seeds on the upper layer of the box body 1 flow out of the through groove 6 with the water flow while the scraper 19 scrapes, and the scraper 19 also continues to descend, adapting to the continuously descending liquid level, ensuring that the dry and damaged seeds on the upper layer are quickly and completely discharged from the box body 1 and fall into the collection box 25.

[0053] Step 3: Open the solenoid valve 3 on the discharge pipe 2 to allow the high-quality seeds with full grains in the lower layer to be discharged from the discharge pipe 2 to the box 1. Subsequently, the high-quality rice seeds with full grains are cleaned and dried to complete the selection of high-quality seeds with full grains.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
