[0002] In the seed production process, impurities such as stems, leaves, spikes, damaged seed fragments, seeds of other crops, weed seeds, mud, sand, and stones are removed from the seeds through impurity removal devices, which can improve the purity of the seeds and ensure their quality.

[0003] Existing seed impurity removal devices generally use air separation and filters to remove impurities. Air separation uses airflow blown by a fan to separate lighter impurities from the seeds and then filters and collects them through a filter. However, during the air separation process, impurities will continuously accumulate on the surface of the filter, affecting the airflow rate. This will reduce the air separation efficiency and further affect the removal of seed impurities.

[0004] To address the problem that existing seed impurity removal devices accumulate impurities on the filter screen surface during air separation, thus affecting airflow throughput and reducing air separation efficiency, thereby further impacting seed impurity removal, a seed impurity removal device is designed to clean the filter screen surface used for collecting impurities during air separation to overcome this issue.

The surface of the main housing 1 is provided with a screening component for filtering impurities, and the outer protective housing 17 is provided with a scraping component for scraping impurities. When the seed production impurity removal device is performing air separation and impurity removal, the screening component can vibrate at a larger amplitude to shake off the impurities on the seed surface. Compared with the existing vibration motor, the amplitude is larger and the shaking effect is better. During the collection process, the scraping component can scrape off the impurities on the surface of the filter screen used to filter and collect impurities and push them to both sides, thereby avoiding the accumulation of impurities on the surface of the filter screen and affecting the ventilation rate of the fan 2.

A side filter screen 16 is fixedly installed on one side of the air outlet 15. A vibrating roller 8 is rotatably connected inside the main housing 1. A motor 7 is fixedly installed on one side of the main housing 1. The output end of the motor 7 passes through one side of the main housing 1 and is fixedly connected to one end of the rotating shaft of the vibrating roller 8. The surface of the vibrating roller 8 is provided with rounded corner protrusions. Rollers 6 are rotatably arranged on both sides of the vibrating plate 4. The rollers 6 are in contact with the surface of the vibrating roller 8. Baffles 5 are fixedly installed on both sides of the upper end of the vibrating plate 4. A side slide plate 9 is fixedly installed on the upper end of the vibrating plate 4. The side slide plate 9 is located below the feed inlet 10.

[0025] Please see Figure 3 , Figure 6 and Figure 7In this embodiment, the scraping assembly includes a first transmission wheel 18, which is fixedly connected to the other end of the vibrating roller 8. A second transmission wheel 19 is rotatably mounted on one side of the main housing 1, and the second transmission wheel 19 is connected to the first transmission wheel 18 via a transmission belt. A worm gear 20 is fixedly connected to one side of the second transmission wheel 19. A reciprocating screw 22 is rotatably mounted on one side of the main housing 1, and a worm wheel 21 is fixedly connected to one end of the reciprocating screw 22. The worm wheel 21 meshes with the worm gear 20. A connecting rod 23 is fixedly mounted on the upper end of the moving component of the reciprocating screw 22. A scraper 24 is fixedly installed at the upper end of the connecting rod 23. One side of the scraper 24 contacts the surface of the side filter screen 16. An opening is provided at the lower end of the air outlet 15. The connecting rod 23 moves at the lower opening of the air outlet 15. A flexible sealing strip 28 is provided at the lower opening of the air outlet 15. The flexible sealing strip 28 contacts the surface of the connecting rod 23. Openings are provided on both sides of the lower end of the air outlet 15. A collection box 26 is fixedly installed at the lower end of the air outlet 15. A side drawer 27 is slidably arranged inside the collection box 26. Wind baffles 25 are fixedly installed on both sides inside the air outlet 15.

[0026] In use, the seeds to be screened are first poured into the feed inlet 10 at the top of the main housing 1. The seeds fall onto the side slide plate 9 below through the feed inlet 10, and then onto the surface of the vibrating plate 4. The motor 7 is started, and the motor 7 drives the vibrating roller 8 to rotate. The surface of the vibrating roller 8 is provided with rounded protrusions. When the vibrating roller 8 rotates at high speed, the rounded protrusions on the surface of the vibrating roller 8 will continuously push up the rollers 6 that are rotated on both sides of the vibrating plate 4, so that the vibrating plate 4 swings with a large amplitude. During the swinging process of the vibrating plate 4, the impurities on the surface of the seeds will fall off with the vibration. Under the action of the fan 2, the lighter impurities will rise with the airflow blown by the fan 2, and the heavier seeds will gradually move towards the discharge port 29 at the bottom of the main housing 1 with the swinging of the vibrating plate 4, and finally be discharged from the discharge port 29.

[0027] Impurities are blown into the upper housing 11 at the top of the main housing 1 by the blower 2. The upper filter 14 is used for airflow and to filter out impurities. Then, the airflow blown out by the blower 2 is blown out from one side of the upper housing 11 through the side connecting pipe 13 and the air inlet 12, thereby blowing the impurities intercepted by the upper filter 14 into the air outlet 15 on the other side of the upper housing 11. The side filter 16 fixedly installed on one side of the air outlet 15 intercepts the impurities.

[0028] After the side filter 16 intercepts impurities, the impurities will continue to accumulate on the surface of the side filter 16, thus affecting ventilation and preventing airflow from flowing normally into the air outlet 15, thus making it impossible to collect impurities. The first transmission wheel 18 is fixedly connected to one end of the shaft of the vibrating roller 8. During the rotation of the vibrating roller 8, the first transmission wheel 18 simultaneously drives the second transmission wheel 19 to rotate. The worm gear 20 fixedly connected to one side of the second transmission wheel 19 simultaneously drives the reciprocating screw 22 to rotate. The connecting rod 23 fixedly connected to the moving component surface of the reciprocating screw 22 simultaneously performs reciprocating motion. The scraper 24 fixedly installed at the upper end of the connecting rod 23 scrapes off the impurities accumulated on the surface of the side filter 16 and pushes them to both sides of the air outlet 15.

[0029] After the impurities are pushed to both sides of the air outlet 15, they fall into the collection box 26 through the openings on both sides of the air outlet 15, thus completing the collection of impurities. After the collection box 26 is saturated with impurities, the side drawer 27 can be pulled out from the collection box 26 to remove the impurities. The baffle 25 is used to block the airflow so that the side filter 16 can fall smoothly into the collection box 26.

[0030] The flexible sealing strip 28 at the lower opening of the air outlet 15 is used to seal the opening at the lower end of the baffle plate 25. This way, when the connecting rod 23 moves, impurities will not flow out from the lower opening of the air outlet 15 into the outer protective housing 17 and affect the operation of the reciprocating screw 22.

[0031] Through the above steps, when the seed production impurity removal device is performing air separation, the screening component can drive the vibrating plate 4 to vibrate at a larger amplitude through the vibrating roller 8 to shake off the impurities on the seed surface. Compared with the existing vibrating motor, the amplitude is larger and the shaking effect is better. The shaken-off impurities are blown into the collection box 26 by the blower 2 for centralized collection. During the collection process, the scraping component operates by rotating the vibrating roller 8, which saves energy consumption. It can also scrape off the impurities on the surface of the side filter screen 16 used to filter and collect impurities and push them to both sides, thereby avoiding the accumulation of impurities on the surface of the side filter screen 16 and affecting the ventilation rate, thus improving the air separation efficiency.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
