A cam motor 2 is fixedly installed on one side of the outer top wall of the screening box 1. The drive end of the cam motor 2 passes through the wall of the screening box 1 and is connected to a drive shaft 3 inside the screening box 1. A pair of cams 4 are installed on the drive shaft 3. A feed inlet 5 is provided on the top wall of the screening box 1. A pair of bearing seats 22 are fixedly installed on both sides of the inner side wall of the screening box 1. A sliding shaft 23 is connected between each pair of bearing seats 22. A bushing 24 is movably fitted on the sliding shaft 23. A screen cylinder 6 is fixedly installed between a pair of bushings 24. A spring 25 is fixedly installed on the bushing 24 on the side in the direction of the cam 4. Three screen plates 7 are magnetically installed inside the screen cylinder 6. The screen cylinder 6 is positioned at each screen plate 7. An impurity discharge port 8 is provided on the side wall. A first discharge port 9 is provided at the bottom of the screening box 1. The screening box 1 is installed directly above the flotation box 14. Electric slide rails 11 are fixedly installed on both sides of the top wall of the flotation box 14. A slider 12 is movably installed between a pair of electric slide rails 11. A scraper 13 is fixedly installed at the bottom of the slider 12. A spiral salt feeder 10 is fixedly installed at the top of the flotation box 14. A waste residue return water tank 15 is provided on one side of the flotation box 14. A waste residue rail 16 is installed on the waste residue return water tank 15. A discharge port 18 is provided at the bottom of the waste residue return water tank 15. A second discharge port 17 is provided at the center of the bottom of the flotation box 14. The flotation box 14 is fixedly installed directly above the collection box 19. A seed collection rail 21 is installed inside the collection box 19. A water pump 20 is fixedly installed inside the collection box 19.
[0020] Furthermore, the spring 25 is fitted onto the slide shaft 23, and the two ends of the spring 25 are respectively fixedly installed on the side wall surfaces of the bearing seat 22 and the bushing 24.
[0021] Furthermore, the outlet of the water pump 20 is connected to the flotation tank 14 via a flexible hose.
[0022] Furthermore, a partition is provided between the flotation tank 14 and the waste residue return water tank 15, and a flat plate is provided above the partition. The side wall of the flat plate in the direction of the flotation tank 14 is a sloping structure, and the water level in the flotation tank 14 is at the position of the flat plate.
[0023] Furthermore, the water delivery rate of the water pump 20 is equal to the water discharge rate of the second discharge port 17.
[0024] Furthermore, the bottom of the scraper 13 has a triangular structure, and the bottom of the scraper 13 is submerged in the water. The scraper 13 is made of soft silicone material.
[0025] Furthermore, both the second discharge port 17 and the water discharge port 18 are located above the collection box 19.
[0026] Furthermore, the screen cylinder 6 passes through the side wall of the screening box 1 in the direction of the impurity discharge port 8, and all three impurity discharge ports 8 are connected to discharge troughs or discharge channels.
[0027] Example: When this device is in use, the cam motor 2 drives the drive shaft 3 to rotate the cam 4. The cam 4 is in contact with the screen cylinder 6. The rotation of the cam causes the screen cylinder 6 to make reciprocating linear motion on the sliding shaft 23, which facilitates screening.
[0028] The diameter of the sieve holes in the three sieve plates 7 decreases from top to bottom, which makes it easier to separate large particles and other impurities from the seeds.
[0029] After being screened, the seeds fall into the flotation tank 14 through the first discharge port 9. Unqualified seeds float on the surface of the liquid, while qualified seeds sink to the bottom of the flotation tank 14 under the action of gravity and enter the collection tank 19 through the second discharge port 17 with the water flow.
[0030] The salinity of the liquid is adjusted by the spiral salt feeder 10 to meet the flotation requirements of different seeds.
[0031] The electric slide rail 11 drives the slider 12 and scraper 13 to move. The scraper 13 scrapes the impurities floating on the water surface into the waste residue return tank 15. The impurities are filtered by the waste residue rail 16 and left in the waste residue rail 16. The brine flows into the collection tank 19 through the drain outlet 18.
[0032] Qualified seeds remain in the seed collection bin 21, and brine falls into the collection tank 19 through the water passage on the seed collection bin 21. The water pump 20 installed in the collection tank 19 sends the water back to the flotation tank 14 for recycling.
