[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a screening device for seed detection, such as... Figure 1-5 As shown, the seed screening device includes: a housing 1 and a partition 2 installed inside the housing 1 to separate the housing 1 into a water selection chamber and a screening chamber; a stirring rod 3 installed in the water selection chamber for stirring corn seeds; a collection box 6 installed on one side of the housing 1 for collecting shriveled seeds; a one-way screw 4 rotatably installed in the water selection chamber, the one-way screw 4 having a scraper 5 threaded on it for scraping shriveled seeds into the collection box 6; and a set of screening boxes 14 installed in the screening chamber for screening seed size.

[0024] In this embodiment, firstly, corn seeds are placed in the water selection chamber of the box 1, and washing water is poured into the water selection chamber. The water level should be at the water level warning line 24. After the seeds are soaked in the water, the shriveled and lighter seeds will float on the water surface. The stirring rod 3 stirs the seeds in the water selection chamber to ensure that all seeds can fully contact the water, making it easier to distinguish the shriveled seeds.

[0025] When shriveled seeds float on the water surface, scraper 5 scrapes them through the feed inlet into collection box 6, achieving automatic collection and improving collection efficiency. After water separation, the seeds are discharged into the screening chamber through the discharge port on partition 2. A set of screening boxes 14 are installed in the screening chamber. These screening boxes 14 screen seeds according to their size, separating seeds of different sizes to facilitate subsequent testing operations. Through the cooperation of unidirectional screw 4 and scraper 5, automatic collection of shriveled seeds is achieved, avoiding the tedious process of repeatedly collecting floating seeds by operators, greatly improving collection efficiency. Seed screening and classification can be achieved through simple operation, simplifying the operation process, reducing labor intensity, and is suitable for screening different varieties of corn seeds. The specifications of screening boxes 14 can be adjusted as needed to meet the requirements of different testing operations.

[0026] In a further preferred embodiment of this utility model, a first motor 7 is fixedly installed on one side of the housing 1, and the output shaft of the first motor 7 is fixedly connected to the one-way screw 4. A feed hopper 8 is fixedly installed on the top of the housing 1. A connecting box 9 is fixedly installed inside the water separation chamber. The connecting box 9 is located below the one-way screw 4 and is rotatably connected to the stirring rod 3. A rotating rod 10 is rotatably installed on the inner wall of the housing 1. The rotating rod 10 is located inside the connecting box 9. Both the rotating rod 10 and the stirring rod 3 are fixedly fitted with bevel gears 11, and the two bevel gears 11 mesh with each other. A second motor 12 is fixedly installed on one side of the housing 1, and the output shaft of the second motor 12 is fixedly connected to the rotating rod 10.

[0027] In this embodiment, when the first motor 7 is started, it drives the one-way screw 4 to rotate, thereby driving the scraper 5 to slide in the water separation chamber to realize the automatic collection of shriveled seeds;

[0028] When the second motor 12 starts, it drives the rotating rod 10 to rotate. Through the transmission of the bevel gear 11, it drives the stirring rod 3 to rotate in the water selection chamber to stir the seeds. The stirring action of the stirring rod 3 helps the seeds to fully contact the water and distinguish shriveled seeds. At the same time, the rotation of the one-way screw 4 drives the scraper 5 to scrape the shriveled seeds floating on the water surface into the collection box 6. Through the cooperation of the first motor 7 and the second motor 12, the stirring and scraping are automated, which greatly improves the screening efficiency.

[0029] In a further preferred embodiment of this utility model, a feed inlet and a drain outlet are provided on one side of the box 1. The feed inlet is located above the drain outlet. A filter screen is installed inside the drain outlet. Both the feed inlet and the drain outlet are connected to the collection box 6. A discharge outlet is provided at the bottom of the partition 2. An electric telescopic rod 27 is fixedly installed at the bottom of the partition 2. A sealing plate 28 is fixedly installed on the output rod of the electric telescopic rod 27. The sealing plate 28 is adapted to the discharge outlet.

[0030] In this embodiment, after the scraper 5 scrapes the shriveled seeds into the collection box 6, the first motor 7 is turned off, and the scraper 5 seals the feed inlet. Then, the electric telescopic rod 27 is activated, causing the sealing plate 28 to slide away from the discharge port, allowing the material to be discharged into the installation box 13 for screening. At the same time, water in the water separation chamber is discharged into the screening chamber, causing the water level in the water separation chamber to drop, while the shriveled seeds are collected in the collection box 6. Through the cooperation of the electric telescopic rod 27 and the sealing plate 28, the opening and closing of the discharge port can be flexibly controlled, achieving the orderly discharge of the screened seeds. Through the reasonable design of the feed inlet and discharge port, the shriveled seeds and the screened seeds can be effectively collected and processed separately, improving the screening efficiency.

[0031] In a further preferred embodiment of the present invention, an installation box 13 is provided inside the screening chamber, and a group of screening boxes 14 are slidably connected to the installation box 13. A connecting plate 15 is fixedly installed at the bottom of the partition 2, and a corrugated pipe 16 is installed on the connecting plate 15. The bottom end of the corrugated pipe 16 is fixedly connected to the installation box 13.

[0032] In this embodiment, the seeds first enter the water selection chamber through the feed hopper 8. After being stirred by the stirring rod 3 and with the cooperation of the one-way screw 4 and the scraper 5, the shriveled seeds are scraped to the collection box 6. The screened seeds enter the screening chamber through the discharge port on the partition 2 (under the control of the electric telescopic rod 27 and the sealing plate 28). Then, the seeds are screened by a set of screening boxes 14. Seeds of different sizes are collected or further processed separately. The sliding connection design between the screening box 14 and the mounting box 13 makes the replacement and adjustment of the screening box simple and quick, improving the flexibility and applicability of the device. The introduction of the corrugated pipe 16 maintains the structural stability and sealing of the screening chamber, preventing seeds from being discharged everywhere.

[0033] In a further preferred embodiment of this utility model, a fixing plate 17 is fixedly installed at the bottom of the mounting box 13, a connecting rod 18 is rotatably installed in the screening chamber, a connecting plate 19 is provided on both the connecting rod 18 and the fixing plate 17, a set of connecting plates 19 are hinged together, a sprocket 20 is fixedly sleeved on both the connecting rod 18 and the rotating rod 10, a chain 21 is sleeved on the two sprockets 20, the chain 21 meshes with the two sprockets 20, a buffer spring 22 is fixedly installed at the bottom of the connecting plate 15, and the bottom end of the buffer spring 22 is fixedly connected to the mounting box 13.

[0034] In this embodiment, when the second motor 12 is started, it drives the rotating rod 10 to rotate. Since the rotating rod 10 and the stirring rod 3 are both fixedly fitted with meshing bevel gears 11, the rotation of the rotating rod 10 will drive the stirring rod 3 to rotate synchronously in the water selection chamber to stir the seeds.

[0035] Simultaneously, the connecting rod 18 rotates synchronously with the stirring rod 3 via chain drive. Since both the connecting rod 18 and the fixed plate 17 are equipped with connecting plates 19, and a set of connecting plates 19 are hinged together, when the connecting rod 18 rotates, it will drive the connecting plates 19 to move. Since the lengths of the connecting plates 19 are different, the shorter connecting plate 19 is fixedly connected to the connecting rod 18. Therefore, when the shorter connecting plate 19 rotates, it will drive the longer connecting plate 19 to rotate synchronously. However, since the connecting rod 18 and the fixed plate 17 are set at the same horizontal level, the movement of the two connecting plates 19 will be converted into the vertical up-and-down movement of the mounting box 13. This vertical up-and-down movement is buffered by the buffer spring 22, which realizes the vibration treatment of the mounting box 13, which facilitates the vibration screening of seeds. Through the combination of stirring and vibration, the seeds are more fully dispersed and screened during the screening process, improving the screening efficiency. Vibration treatment helps to remove impurities or moisture adhering to the seed surface, making the screened seeds cleaner and tidier.

[0036] In a further preferred embodiment of the present invention, a glass observation window 23 is fitted on one side of the housing 1. The glass observation window 23 is located on one side of the water separation chamber, and a water level warning line 24 is engraved on the glass observation window 23.

[0037] In this embodiment, the glass observation window 23 is located on one side of the water selection chamber, allowing the operator to directly observe the water level and seed selection process within the chamber without opening the housing 1. A water level warning line 24 is engraved on the glass observation window 23, serving as a reference mark to indicate the appropriate water level range within the chamber. When the water level is below or above the warning line, the operator can make adjustments accordingly to ensure the normal operation of the selection process. The water level warning line 24 provides the operator with a clear water level reference, ensuring that the water level within the chamber is always maintained at an appropriate level, thereby optimizing the selection effect and improving the seed selection quality.

[0038] In a further preferred embodiment of the present invention, an operation port is provided on one side of the housing 1, the operation port is located on one side of the mounting box 13, a door 25 is hinged in the operation port, a clip 26 is rotatably installed on one side of the housing 1, and the arc-shaped stop of the clip 26 is in rotatable contact with one side of the door 25.

[0039] In this embodiment, when the door 25 is closed, the arc-shaped stop of the locking piece 26 will abut against the door 25. By rotating the locking piece 26, the door 25 can be locked or unlocked, thereby ensuring the stability and safety of the screening device during operation. After the seeds are screened, the door 25 can be opened to take out the screening box 14. The introduction of the locking piece 26 provides a reliable locking mechanism for the door 25, ensuring the stability and safety of the screening device during operation and avoiding safety hazards caused by accidental opening of the door.

[0040] In summary, compared with related technologies, this device, through a dual screening process of water selection and sieving, can more effectively remove shriveled, damaged, and other defective seeds, improve the accuracy of subsequent testing, and simultaneously achieve automatic collection of shriveled seeds, effectively improving collection efficiency.

[0041] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
