Description

Technical Field

[0001] This utility model relates to the field of crop breeding technology, specifically to a flotation device for crop breeding with waste seed separation function. Background Technology

[0002] In agricultural production, the quality of crop varieties directly affects grain yield, agricultural product quality, and farmers' economic benefits. High-quality crop seeds possess stronger resistance to pests and diseases, higher yield potential, and better quality characteristics, playing a crucial role in ensuring global food security and promoting sustainable agricultural development. Therefore, crop breeding has always been a core component of agricultural research and production. In the process of crop breeding, seed selection and separation are essential steps.

[0003] For example, Chinese utility model patent application number 202221354111.9 discloses a seed screening device for seedling cultivation. Through a set stirring component and a screening component, small seeds can be screened out during seed movement. After the initial screening, a set flotation component uses the buoyancy of water flow to screen out seeds that are not fully plump, ensuring that only plump seeds remain in the placement container. However, this device still has certain shortcomings.

[0004] Before flotation, seeds may clump together, reducing the screening efficiency. At the same time, hollow or damaged seed shells tend to adhere to high-quality seeds. They should float on the surface of the flotation solution, but after adhering to normal seeds, the combined buoyancy characteristics of the two become complicated, interfering with the flotation effect.

[0005] Therefore, we propose a flotation device for crop breeding with waste seed separation function in order to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a flotation device for crop breeding with a waste seed separation function, in order to solve the problems mentioned in the background art, such as the possibility of seed clumping before seed flotation, which reduces the seed screening efficiency, and the tendency of hollow or damaged seed shells to adhere to high-quality seeds. These shells, which should float on the surface of the flotation solution, become complex in buoyancy after adhering to normal seeds, thus interfering with the flotation effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flotation device for crop breeding with waste seed separation function, comprising a device body, a conveying pipe installed on the left side of the device body via a connecting component, and a conveying auger installed inside the conveying pipe, a connecting plate installed on the right side of the device body, a second servo motor installed below the connecting plate, a transmission shaft installed above the second servo motor via an output shaft, a stirring tank installed inside the device body via a fixing block, a connecting strip installed on the upper right side of the stirring tank, and a stirring component installed below the connecting strip;

[0008] The device body has a support plate installed inside, and the support plate has through holes. The front and rear sides of the right side of the support plate are equipped with inclined plates, and vertical plates are installed on the inclined surfaces of the inclined plates. A third servo motor is installed on the front surface of the vertical plate, and a scraper assembly is installed on the rear side of the third servo motor through the output shaft.

[0009] A flotation box is installed inside the lower part of the device body, and a waste seed box is installed on the right side of the flotation box. A seed collection box is installed inside the lower part of the device body.

[0010] Preferably, a first servo motor is installed on the left side of the conveying pipe, and the right side of the first servo motor is connected to the conveying auger through an output shaft. A feed inlet is installed on the top of the conveying pipe, and the right end of the conveying pipe is located above the mixing tank.

[0011] With the above structural design, the first servo motor works in conjunction with the conveying auger to transport the seeds from the feed inlet to the mixing tank, preventing the seeds from clumping during the feeding process, providing uniform seed raw materials for the subsequent mixing process, ensuring the mixing effect, thereby improving the efficiency and accuracy of the entire flotation separation, and ensuring the stable operation of the equipment.

[0012] Preferably, the stirring assembly is connected to the connecting strip via a bearing seat, and the drive shaft is connected to the stirring assembly via a connecting belt. Both the drive shaft and the stirring assembly are equipped with pulleys.

[0013] With the above structural design, the second servo motor drives the stirring component to rotate, which can effectively break up clumps of seeds and shake off impurities adsorbed on normal seeds. This solves the key problem affecting the flotation effect, improves the accuracy of flotation separation, and ensures that high-quality seeds are screened out.

[0014] Preferably, a discharge pipe is installed below the mixing tank, and an electrically controlled valve is installed on the discharge pipe, with the center line of the discharge pipe coinciding with the center line of the through hole.

[0015] The above structural design ensures that the stirred seeds can enter the flotation tank smoothly and accurately, guaranteeing the continuity and stability of the flotation process and improving the overall operating efficiency of the equipment.

[0016] Preferably, the scraper assembly is located above the flotation tank, and the inner bottom surface of the flotation tank has an inclined structure design.

[0017] The above structural design utilizes the principle of buoyancy to accurately scrape the waste seeds floating on the surface of the flotation solution into the waste seed box. At the same time, the inclined bottom surface facilitates the movement of plump seeds towards the collection area, improving the separation effect between waste seeds and plump seeds and ensuring the accuracy of seed screening.

[0018] Preferably, the flotation tank and the seed collection tank are connected by a first connecting pipe, and the seed collection tank and the waste seed tank are connected by a second connecting pipe. Both the first and second connecting pipes are equipped with control valves.

[0019] The above structural design facilitates the control of the flow of seeds and flotation solution between different tanks, enabling the separate collection of saturated seeds and waste seeds. It also facilitates the rational treatment and recycling of flotation solution, improving the practicality and environmental friendliness of the equipment.

[0020] Preferably, a first filter screen and a second filter screen are installed inside the waste seed box and the seed collection box, respectively. The first filter screen and the second filter screen are detachably connected to the waste seed box and the seed collection box, respectively. A drain pipe is installed on the right side of the seed collection box, and the drain pipe is connected to an external liquid collection box.

[0021] The above structural design facilitates the cleaning of residual impurities inside the equipment, ensuring internal cleanliness, while also enabling the recycling of flotation solution, reducing production costs, conforming to environmental protection principles, and extending the service life of the equipment.

[0022] Compared with the prior art, the beneficial effects of this utility model are: This flotation equipment for crop breeding with waste seed separation function:

[0023] 1. High-efficiency pretreatment: The seeds are conveyed by the first servo motor-driven conveyor auger and the second servo motor drives the stirring component to stir, effectively breaking up the clumps of seeds and shaking off the impurities adsorbed on the normal seeds, which improves the efficiency and accuracy of subsequent flotation, ensures that the flotation process is not disturbed, and improves the screening effect.

[0024] 2. Precise separation: Utilizing the flotation principle, combined with the scraper assembly and the inclined bottom surface design of the flotation tank, it can accurately separate waste seeds from plump seeds, improving the accuracy of seed screening, ensuring that the collected seeds are of excellent quality, which is beneficial to the cultivation and growth of crops and provides high-quality seed resources for agricultural production.

[0025] 3. Easy to clean and recycle: The first and second filters in the waste seed box and seed collection box are removable, making it easy to clean residual impurities and ensure the cleanliness of the equipment. At the same time, the drain pipe discharges the separated flotation liquid to the external liquid collection box, which facilitates the recycling of the flotation liquid, reduces production costs, and conforms to the concept of environmental protection and sustainable development.

The device is internally equipped with a conveying auger 6. A connecting plate 7 is installed on the right side of the main body 1, and a second servo motor 8 is installed below the connecting plate 7. A drive shaft 9 is installed above the second servo motor 8 via an output shaft. A mixing tank 13 is installed inside the main body 1 via a fixing block, and a connecting strip 10 is installed on the upper right side of the mixing tank 13.

When the second servo motor 8 is started, the second servo motor... The output shaft of machine 8 drives the transmission shaft 9 to rotate. When the transmission shaft 9 rotates, it drives the stirring assembly 11 to rotate through the connecting belt 12. The stirring assembly 11 stirs the seeds in the stirring tank 13, which can shake off the hollow or damaged seed shells adsorbed on normal seeds, thus solving the problem of seed clumping and impurity adsorption interfering with the flotation effect. A feed pipe 14 is installed below the stirring tank 13, and an electric control valve 15 is installed on the feed pipe 14. The center line of the feed pipe 14 coincides with the center line of the through hole 17. After stirring is completed, the electric control valve 15 is opened, and the seeds enter the flotation tank 22 for flotation through the feed pipe 14 and the through hole 17 on the support plate 16.

[0035] A support plate 16 is installed inside the main body 1 of the device, and a through hole 17 is provided on the support plate 16. Inclined plates 18 are installed on both the front and rear right sides of the support plate 16, and vertical plates 19 are installed on the inclined surfaces of the inclined plates 18. A third servo motor 20 is installed on the front surface of the front vertical plate 19, and a scraper assembly 21 is installed on the rear side of the third servo motor 20 via an output shaft. The scraper assembly 21 is located above the flotation tank 22. The inner bottom surface of the flotation tank 22 has an inclined structure design, resulting in a full... Because of their higher density, the seeds sink to the bottom of the flotation tank 22, while hollow or damaged waste seeds float on the surface of the flotation liquid. The third servo motor 20 is started, which drives the scraper assembly 21 to rotate. The scraper assembly 21 scrapes the waste seeds floating on the surface of the flotation liquid to the right side of the flotation tank 22, so that they enter the waste seed box 23 through the second connecting pipe 26. When the flotation liquid is insufficient, the box door of the device body 1 can be opened to add flotation liquid in time, so that the waste seeds float on the upper surface of the flotation tank 22 for easy scraping.

[0036] A flotation tank 22 is installed at the lower part of the device body 1. The flotation tank 22 is connected to the seed collection tank 24 via a first connecting pipe 25, and the seed collection tank 24 is connected to the waste seed tank 23 via a second connecting pipe 26.

The first filter screen 27 in the waste seed tank 23 can separate the waste seeds from the flotation liquid. The flotation liquid is transported to the seed collection tank 24 through the second connecting pipe 26 and discharged through the drain pipe 29 from the seed collection tank 24.

[0037] Working principle: When using this flotation equipment for crop breeding with waste seed separation function, firstly, the crop seeds to be screened are poured into the conveying pipe 3 through the feed inlet 4. The first servo motor 5 is started, which drives the conveying auger 6 to rotate. The conveying auger 6 conveys the seeds to the right along the conveying pipe 3 until they fall into the mixing tank 13, preventing seed clumping. Then, the second servo motor 8 is started, and the output shaft of the second servo motor 8 drives the transmission shaft 9 to rotate. When the transmission shaft 9 rotates, it drives the stirring component 11 to rotate through the connecting belt 12. The stirring component 11 stirs the seeds in the mixing tank 13, which can shake off the hollow or damaged seed shells adsorbed on normal seeds, solving the problem of seed clumping and impurity adsorption interfering with the flotation effect.

[0038] After stirring, open the electric control valve 15. The seeds enter the flotation tank 22 through the feed pipe 14 and the through hole 17 on the support plate 16 for flotation. The plump seeds sink to the bottom of the flotation tank 22 due to their higher density, while the hollow or damaged waste seeds float on the upper layer of the flotation liquid. Start the third servo motor 20. The third servo motor 20 drives the scraper assembly 21 to rotate. The scraper assembly 21 scrapes the waste seeds floating on the upper layer of the flotation liquid to the right side of the flotation tank 22, so that they enter the waste seed box 23 through the second connecting pipe 26. When the flotation liquid is insufficient, the box door of the device body 1 can be opened to add flotation liquid in time, so that the waste seeds float on the upper surface of the flotation tank 22 for easy scraping.

[0039] After flotation is completed, the control valve on the first connecting pipe 25 is opened, and the saturated seeds and flotation liquor enter the seed collection tank 24. The second filter screen 28 in the seed collection tank 24 filters the seeds, separating the flotation liquor, which is discharged through the drain pipe 29. After screening, the saturated seeds remain in the seed collection tank 24, completing the separation of waste seeds and the collection of high-quality seeds. The first filter screen 27 in the waste seed tank 23 separates the waste seeds from the flotation liquor, which is then transported to the seed collection tank 24 through the second connecting pipe 26. The flotation liquor is then discharged through the drain pipe 29 from the seed collection tank 24, thus completing a series of processes. Content not described in detail in this specification belongs to prior art known to those skilled in the art.
