DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] Example 1, reference Figure 1-4 A wheat seed separation device comprises a brine tank 12 and a first feed port 11: two mounting frames 13 are symmetrically installed on the upper part of the brine tank 12, two discs 3 are installed between the two mounting frames 13 through a rotating shaft 15, and a plurality of net boxes 7 are movably connected between the two discs 3 through a suspension structure. The suspension structure comprises a fixed rod 4, a sleeve 5 and a connecting rod 6. The fixed rod 4 is installed between the two discs 3, and two sleeves 5 are sleeved on the outside of the fixed rod 4. A connecting rod 6 is hinged between the sleeve 5 and the upper end of one side of the net box 7, and the two connecting rods 6 on the same side are vertically arranged.

[0046] When the net box 7 rotates with the disc 3, it will enter the salt water tank 12 in sequence, and the upper part of the net box 7 is always facing upward, and the bottom of the net box 7 is set in a cone shape;

[0047] A driving structure is arranged between one of the mounting frames 13 and the disc 3, and the driving structure includes a water pipe 2 and a regulating component 14. The water pipe 2 is connected to the water supply equipment through a pipeline. The regulating component 14 includes blades 1401, cotton cloth 1402 and circular holes 1403. Several blades 1401 are distributed in a circular array on the outside of the rotating shaft 15. The cotton cloth 1402 is fixed to the far end of the blade 1401 by rivets. The cotton cloth 1402 is evenly provided with several circular holes 1403. Water coming out of the water outlet at the lower end of the water pipe 2 just falls on the cotton cloth 1402 at the upper end of the blade 1401. The inside of the net box 7 is symmetrically provided with material turning and separation components.

[0048] The material turning and separation assembly includes guide rails 8, limit plates 9, floating plates 10 and auxiliary turning assembly 23. The guide rails 8 are opened in parallel on both sides of the net box 7. The two ends of the floating plate 10 are slidably arranged on the inner side of the two guide rails 8. The limit plates 9 are installed at both ends of the floating plates 10 outside the net box 7. A groove 26 is arranged at the upper end of the floating plate 10 along the long side direction, and when the floating plate 10 slides, the limit plates 9 move in accordance with the outer surface of the net box 7.

[0049] The water pipe 2 is connected to the water supply equipment through a water pump. The salt water falling from the water pipe 2 falls directly on the blades 1401. In the process of the salt water colliding with the blades 1401, the salt water transfers kinetic energy to the blades 1401, thereby driving the rotating shaft 15 to rotate. At the same time, the first discharge port 11 below is used to discharge part of the water and the screened bad seeds together. The amount of water falling from the water pipe 2 per unit time matches the amount of water discharged from the first discharge port 11, ensuring that the water level in the salt water tank 12 remains at a stable level.

[0050] When the rotating shaft 15 drives the disc 3 to rotate, the position of the net box 7 on the disc 3 will change. During the process of the net box 7 changing its position, the fixing rod 4 and the sleeve 5 rotate relative to each other, so that the upper open end of the net box 7 always remains in a vertical upward state. When the net box 7 enters the brine tank 12 and is immersed in the brine inside it, the brine will enter from various parts of the net box 7. At this time, the seeds in the net box 7 will contact with the brine. At this time, the seeds with full particles will not float up due to contact with the brine, but some shriveled and bad seeds will float to the water surface during contact with the brine, thereby screening the bad seeds.

[0051] The screened out bad seeds float on the water surface and may enter the next net box 7 that is about to enter the brine tank 12. Therefore, the brine falling in the water pipe 2 not only provides power, but also part of the water falling from the water pipe 2 falls on the inner side of the brine tank 12, which can arouse ripples on the water surface inside the brine tank 12. In conjunction with the first discharge port 11 that always transports water outward, the water flows toward the position of the first discharge port 11, accelerating the movement of the bad seeds close to the first discharge port 11, and finally being discharged from the first discharge port 11.

[0052] But some bad seeds may appear at the bottom of the net box 7, and the good seeds covered on top make it impossible for the bad seeds to float up smoothly.

[0053] To this end, when the net box 7 enters the brine tank 12 and comes into contact with the brine, the float 10 between the two guide rails 8 will be affected by the buoyancy and move upward. In the process of the float 10 moving upward, the seeds are turned over with the help of the groove 26 at the upper end of the float 10 and the multiple groups of auxiliary turning components 23 arranged on both sides. In this way, the bad seeds at the bottom move upward during the turning process and float smoothly in contact with the brine.

[0054] Example 2, reference Figure 7-10 , the difference between this embodiment and embodiment 1 is that the auxiliary flipping assembly 23 includes a slot 2301, a ring 2302 and a straight rod 2303;

[0055] A plurality of straight rods 2303 are horizontally distributed on both sides of the floating plate 10 in a symmetrical manner, a plurality of circular rings 2302 are rotatably arranged on the outer sides of the straight rods 2303 , and slots 2301 are provided on the outer surfaces of the circular rings 2302 .

[0056] Some of the screened seeds have dust-like impurities adhering to the outer surface. If they are not cleaned in time, the collected seeds still need to be cleaned after the seeds are screened.

[0057] To this end, when the floating plate 10 moves upward, the multiple straight rods 2303 connected on both sides thereof can not only flip the seeds, but also contact the outer surface of the seeds through the circular ring 2302 sleeved on the outside of the straight rod 2303 and the groove 2301 on the outer surface of the circular ring 2302. During the contact process, the circular ring 2302 will rotate. When the circular ring 2302 rotates, the outer surface of the seed can be cleaned by taking advantage of the opportunity when the external groove 2301 contacts the seed.

[0058] Example 3, reference Figure 5-6The difference between this embodiment and embodiment 1 and embodiment 2 is that a feeding pipe 1 is arranged between the upper part of the disc 3, and the feeding pipe 1 is connected to the feeding equipment, and the feeding pipe 1 is controlled to feed into the net box 7 located at the highest point at a fixed time and quantity. A support frame 16 is vertically installed on one side of the upper end of the brine tank 12, and an auxiliary feeding structure is arranged on the side of the support frame 16 close to the disc 3. The auxiliary feeding structure includes a second feeding port 17, a toggle rod 18, a feeding rod 19 and a column 20. The second feeding port 17 is opened on the support frame 16, and the bottoms of several feeding rods 19 are hinged on the support frame 16 at the lower edge of the second feeding port 17, and the feeding rod 19 is arranged to be tilted upward and extend to the lower side of the net box 7. The toggle rod 18 is horizontally symmetrically arranged on one side of the support frame 16, and columns 20 are arranged on both sides of the net box 7. When the net box 7 moves toward the side of the support frame 16, the column 20 and the toggle rod 18 above contact each other.

[0059] A notch 22 is also provided on one side of the net box 7 close to the support frame 16. A baffle 21 is provided on the support frame 16. The baffle 21 fits the lower ends of a plurality of feed rods 19 so that the feed rods 19 can only rotate upward.

[0060] After all the net boxes 7 on the disc 3 are filled with seeds and screened, if automatic feeding and replenishing cannot be achieved, the equipment needs to be stopped and refilled. Such operations are too cumbersome, just like traditional screening methods.

[0061] To this end, a support frame 16 is set on one side of the salt water tank 12, and the rotation direction of the disc 3 is clockwise. It can be inferred from the process that the water pipe 2 drives the rotating shaft 15 to rotate that when the net box 7 comes out of the salt water tank 12, the seed screening work has been completed. When the net box 7 comes to the support frame 16, the net box 7 first contacts with the discharge rod 19. During the contact process, since the discharge rod 19 is hinged on the support frame 16, the lower end of the discharge rod 19 is on the support frame 16. The baffle 21 can prevent the feeding rod 19 from deflecting downward, and the feeding rod 19 can only deflect upward. When the feeding rod 19 deflects upward, the net box 7 also continues to move upward. Since the bottom of the net box 7 is conical, the net box 7 and the feeding rod 19 are separated during the process of the net box 7 continuing to move upward, causing the feeding rod 19 to return to the bottom of the net box 7. At the same time, the column 20 connected to the side of the net box 7 will contact the toggle rod 18 installed on the support frame 16, and the column 20 will contact the toggle rod 18. The rod 18 has an upward force, but since the position of the toggle rod 18 is fixed, under the influence of the reaction force, the net box 7 is deflected together with the column 20. During the deflection, a rotation occurs between the sleeve 5 and the fixed rod 4 to ensure that the net box 7 can be deflected. When the net box 7 deflects to one side of the support frame 16, the seeds inside the net box 7 will leak out from the gap 22 and fall on the upper ends of several feeding rods 19. The seeds roll down along the gap between two adjacent feeding rods 19, are discharged and collected from the second feeding port 17, and the seed feeding is completed. When the net box 7 deflects a certain angle, the column 20 and the toggle rod 18 are separated. Under the action of the net box 7's own gravity, the position of the net box 7 is restored to its initial state. When the net box 7 moves to the highest point, the feeding pipe 1 performs quantitative feeding. Since the time interval between the two adjacent net boxes 7 moving to the highest point is constant, the feeding pipe 1 controls the feeding according to the realization of this interval to match the movement speed of the net box 7.

[0062] Example 4, reference Figure 7 and Fig. 9 The difference between this embodiment and Embodiment 1, Embodiment 2 and Embodiment 3 is that two bubble generating components are arranged on both sides of the inner wall of the mesh box 7; the bubble generating component includes a paddle 24 and a metal spring 25, and a plurality of metal springs 25 are distributed on the inner wall of the mesh box 7 in a linear array in the vertical direction. The paddle 24 is installed on both sides of the floating plate 10, and the upper end surface of the metal spring 25 and the lower end surface of the floating plate 10 are both provided with slopes. When the floating plate 10 rises, the paddle 24 and the metal spring 25 contact each other and drive the metal spring 25 to vibrate. When the floating plate 10 falls back, the slope on the paddle 24 slides down along the slope on the metal spring 25.

[0063] In order to increase the buoyancy of the bad seeds, during the rising process of the float plate 10, the paddles 24 on both sides contact with the metal springs 25 inside the net box 7, and drive the metal springs 25 to vibrate through the corners of the paddles 24. The metal springs 25 will produce some bubbles during the vibration process. When these bubbles are combined with the bad seeds, the buoyancy of the bad seeds will be increased. This is because when bubbles are trapped inside an object or attached to the surface of an object, they will occupy a certain volume. According to Archimedes' principle, the buoyancy of an object in a fluid is equal to the weight of the fluid it displaces. When bubbles are attached to an object, they actually increase the total volume of the liquid displaced by the object, thereby increasing the buoyancy of the object. Even if the density of the object itself is greater than the density of the liquid, the presence of bubbles can enable the object to obtain sufficient buoyancy to rise in the liquid.

[0064] Secondly, when the net box 7 leaves the brine tank 12 and unloads the seeds inside, the float 10 will fall back along the guide rail 8. During the falling process, the lower end of the paddle 24 and the upper end of the metal spring 25 are both provided with slopes, and the thickness of the slope is small and easy to deform. During the falling process of the float 10, under the action of the gravity of the float 10 itself, the slope on the paddle 24 and the slope on the metal spring 25 squeeze each other and pass through each other, ensuring the smooth falling of the float 10.

[0065] The working principle of the device is:

[0066] The water pipe 2 is connected to the water supply equipment through a water pump. The salt water falling from the water pipe 2 falls directly on the blades 1401. In the process of the salt water colliding with the blades 1401, the salt water transfers kinetic energy to the blades 1401, thereby driving the rotating shaft 15 to rotate. The support frame 16 is U-shaped, which can block part of the splashing water flow. At the same time, the first discharge port 11 below is used to discharge part of the water and the screened bad seeds together. The water falling from the water pipe 2 per unit time is matched with the water discharged from the first discharge port 11, ensuring that the water level in the salt water tank 12 is maintained at a stable level.

[0067] When the rotating shaft 15 drives the disc 3 to rotate, the position of the net box 7 on the disc 3 will change. During the process of the net box 7 changing its position, the fixing rod 4 and the sleeve 5 rotate relative to each other, so that the upper open end of the net box 7 always remains in a vertical upward state. When the net box 7 enters the brine tank 12 and is immersed in the brine inside it, the brine will enter from various parts of the net box 7. At this time, the seeds in the net box 7 will contact with the brine. At this time, the seeds with full particles will not float up due to contact with the brine, but some shriveled and bad seeds will float to the water surface during contact with the brine, thereby screening the bad seeds.

[0068] The screened-out bad seeds float on the water surface and may enter the next net box 7 that is about to enter the brine tank 12. Therefore, the brine falling from the water pipe 2 not only provides power, but also part of the water falling from the water pipe 2 falls on the inner side of the brine tank 12, which can arouse ripples on the water surface inside the brine tank 12. In conjunction with the first discharge port 11 that always transports water outward, the water flows toward the position of the first discharge port 11, accelerating the movement of the bad seeds toward the first discharge port 11, and finally being discharged from the first discharge port 11.

[0069] But some bad seeds may appear at the bottom of the net box 7, and the good seeds covered on top make it impossible for the bad seeds to float up smoothly.

[0070] To this end, when the net box 7 enters the brine tank 12 and comes into contact with the brine, the float 10 between the two guide rails 8 will be affected by the buoyancy and move upward. In the process of the float 10 moving upward, the seeds are turned over with the help of the groove 26 at the upper end of the float 10 and the multiple groups of auxiliary turning components 23 arranged on both sides. In this way, the bad seeds at the bottom move upward during the turning process and float smoothly in contact with the brine.

[0071] In order to increase the buoyancy of the bad seeds, during the rising process of the float plate 10, the paddles 24 on both sides contact with the metal springs 25 inside the net box 7, and drive the metal springs 25 to vibrate through the corners of the paddles 24. The metal springs 25 will produce some bubbles during the vibration process. When these bubbles are combined with the bad seeds, the buoyancy of the bad seeds will be increased. This is because when bubbles are trapped inside an object or attached to the surface of an object, they will occupy a certain volume. According to Archimedes' principle, the buoyancy of an object in a fluid is equal to the weight of the fluid it displaces. When bubbles are attached to an object, they actually increase the total volume of the liquid displaced by the object, thereby increasing the buoyancy of the object. Even if the density of the object itself is greater than the density of the liquid, the presence of bubbles can enable the object to obtain sufficient buoyancy to rise in the liquid.

[0072] Secondly, when the net box 7 leaves the brine tank 12 and unloads the seeds inside, the float 10 will fall back along the guide rail 8. During the falling process, the lower end of the paddle 24 and the upper end of the metal spring 25 are both provided with slopes, and the thickness of the slope is small and easy to deform. During the falling process of the float 10, under the action of the gravity of the float 10 itself, the slope on the paddle 24 and the slope on the metal spring 25 squeeze each other and pass through each other, ensuring the smooth falling of the float 10.

[0073] Some of the screened seeds have dust-like impurities adhering to the outer surface. If they are not cleaned in time, the collected seeds still need to be cleaned after the seeds are screened.

[0074] To this end, when the floating plate 10 moves upward, the multiple straight rods 2303 connected on both sides thereof can not only flip the seeds, but also contact the outer surface of the seeds through the circular ring 2302 sleeved on the outside of the straight rod 2303 and the groove 2301 on the outer surface of the circular ring 2302. During the contact process, the circular ring 2302 will rotate. When the circular ring 2302 rotates, the outer surface of the seed can be cleaned by taking advantage of the opportunity when the external groove 2301 contacts the seed.

[0075] After all the net boxes 7 on the disc 3 are filled with seeds and screened, if automatic feeding and replenishing cannot be achieved, the equipment needs to be stopped and refilled. Such operations are too cumbersome, just like traditional screening methods.

[0076] To this end, a support frame 16 is set on one side of the salt water tank 12, and the rotation direction of the disc 3 is clockwise. It can be inferred from the process that the water pipe 2 drives the rotating shaft 15 to rotate that when the net box 7 comes out of the salt water tank 12, the seed screening work has been completed. When the net box 7 comes to the support frame 16, the net box 7 first contacts with the feed rod 19. During the contact process, since the feed rod 19 is hinged on the support frame 16, the baffle 21 on the support frame 16 at the lower end of the feed rod 19 can prevent the feed rod 19 from being discharged. The material rod 19 deflects downward, and the material discharge rod 19 can only deflect upward. When the material discharge rod 19 deflects upward, the net box 7 also continues to move upward. Since the bottom of the net box 7 is conical, when the net box 7 continues to move upward, the net box 7 and the material discharge rod 19 separate, causing the material discharge rod 19 to return to the bottom of the net box 7. At the same time, the column 20 connected to the side of the net box 7 will contact the toggle rod 18 installed on the support frame 16. The column 20 has an upward force on the toggle rod 18, but because the toggle rod 1 8 is fixed in position. At this time, under the influence of the reaction force, the net box 7 and the column 20 are deflected together. During the deflection, the sleeve 5 and the fixed rod 4 rotate relative to each other to ensure that the net box 7 can be deflected. When the net box 7 deflects to one side of the support frame 16, the seeds inside the net box 7 will leak out from the gap 22 and fall on the upper ends of several discharge rods 19. The seeds roll down along the gap between two adjacent discharge rods 19, are discharged and collected from the second discharge port 17, and the seed discharge is completed. When the net box 7 deflects a certain angle Afterwards, the column 20 is separated from the toggle rod 18, and the position of the net box 7 is restored to its initial state under the action of its own gravity. When the net box 7 moves to the highest point, the feeding pipe 1 carries out quantitative feeding. Since the time interval between two adjacent net boxes 7 moving to the highest point is certain, the feeding pipe 1 controls the feeding according to the realization of this interval, so as to match the movement speed of the net box 7. The feeding interval time of the feeding pipe 1 is set by the control program, which is a commonly used method in the prior art and will not be elaborated here.
