[0002] Seed vigor is a key factor in determining seed germination and seedling growth. Hyperspectral imaging can detect the physiological state inside seeds, so hyperspectral imaging technology is usually used to identify seed quality. Before hyperspectral imaging quality inspection, seeds are generally screened to ensure the consistency of seed samples.

[0003] After searching, a Chinese patent with a publication number of CN220879589U discloses an agricultural seed impurity removal and screening device, which can screen heavier mud blocks, sand and gravel particles, and foreign crop seeds into a collection box to improve the seed screening quality and thus improve the sowing success rate. However, for seeds that need to undergo hyperspectral imaging quality inspection, it is necessary to ensure that the seed particle sizes are relatively small, that is, to ensure the consistency of the seed samples, and the device cannot screen out seeds with larger particles. A seed screening device disclosed in a Chinese patent with a publication number of CN220425922U uses two sieve plates, but during its use, the material on the sieve plate is not easy to be discharged, so that the material accumulates on the sieve plate and affects the screening efficiency.

[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0028] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0029] See also Figure 1-9 The present invention provides a seed quality inspection and screening device using hyperspectral imaging, which is used for screening seeds for hyperspectral imaging quality inspection and has the effect of ensuring sample consistency. The technical solution is as follows:

[0030] A seed quality inspection and screening device with hyperspectral imaging comprises an equipment box 1, in which two screening assemblies 2 are movably arranged, the front and rear sides of the screening assemblies 2 are fixedly connected with springs 3 for resetting, the front side of the screening assemblies 2 is fixedly connected with a force-bearing rod 4, the front side of the equipment box 1 is rotatably connected with a rotating shaft 5, the surface of the rotating shaft 5 is fixedly connected with a driving block 6, the rotation of the driving block 6 can intermittently push the two force-bearing rods 4, and the front side of the equipment box 1 is provided with a rotating part for driving the driving block 6 to rotate.

[0031] Specifically, two screening components 2 are provided, the upper screening component 2 is used to screen out seeds with larger particles, so that seeds that meet the particle size fall into the lower screening component 2, and the lower screening component 2 is used to screen out seeds with smaller particle sizes, so that seeds with smaller particle sizes pass through the lower screening component 2, and seeds with smaller particle size differences are retained on the lower screening component 2. These seeds can ensure the consistency of seed samples when used for hyperspectral imaging quality inspection.

[0032] A cavity 7 is provided in the middle of the upper surface of the equipment box 1 , and slide grooves 8 are respectively opened on the inner walls of the cavity 7 . Two screening components 2 are respectively slidably set in the two slide grooves 8 , and one end of the spring 3 away from the screening component 2 is fixedly connected to the inner wall of the slide groove 8 .

[0033] An inclined force-bearing surface 9 is provided on the left side of the upper force-bearing rod 4 and the right side of the lower force-bearing rod 4, and an inclined extrusion surface 10 is provided on the left side of the driving block 6. When the driving block 6 rotates, the extrusion surface 10 can be driven to intermittently contact the two force-bearing surfaces 9, and the angles of the force-bearing surface 9 and the extrusion surface 10 are the same.

[0034] The rotating member includes a frame 11 fixedly connected to the front of the equipment box 1 , a motor 12 is fixedly connected to the front of the frame 11 , and an output end of the motor 12 is fixedly connected to one end of the rotating shaft 5 .

[0035] Specifically, the output end of the motor 12 drives the rotating shaft 5 to rotate clockwise, thereby driving the driving block 6 to rotate clockwise, thereby driving the extrusion surface 10 to rotate. When the extrusion surface 10 rotates, it intermittently contacts the upper and lower force-bearing surfaces 9 and generates pressure thereon, thereby driving the force-bearing rod 4 to move backward, thereby driving the screening assembly 2 to move backward to overcome the pressure of the spring 3. When the driving block 6 is separated from the force-bearing rod 4, the spring 3 is reset to drive the screening assembly 2 to move, thereby causing the screening assembly 2 to vibrate, thereby improving the screening efficiency.

[0036] The two screening assemblies 2 are staggered and tilted, and the screening assembly 2 includes a sliding plate 201, a through hole is formed on the upper surface of the sliding plate 201, and a screen plate 202 is fixedly connected to the inner wall of the through hole, and a guide portion 203 is formed at the tail of the sliding plate 201, and the guide portion 203 extends to the outside of the equipment box 1.

[0037] The diameter of the sieve holes of the upper sieve plate 202 is larger than that of the sieve holes of the lower sieve plate 202. Discharge ports 13 are provided on both sides of the equipment box 1. A sliding opening is provided at the bottom of the front of the equipment box 1, and a collection box 14 extending into the cavity 7 is provided in the sliding opening.

[0038] A cover plate 15 is fixedly connected to the inner wall of the cavity 7 , and a feed hopper 16 in communication with the cavity 7 is fixedly connected to the upper surface of the cover plate 15 .

[0039] Specifically, by tilting the screening component 2, with the cooperation of the discharge port 13, the material on the screen plate 202 can be discharged in time to avoid affecting the screening efficiency due to material accumulation. By setting the sieve hole diameter of the upper screen plate 202 to be larger than the sieve hole diameter of the lower screen plate 202, the upper screening component 2 is used to screen out seeds with larger particles, so that seeds that meet the particle size fall into the lower screening component 2, and the lower screening component 2 is used to screen out seeds with smaller particle sizes, so that seeds with smaller particle sizes pass through the lower screening component 2, and then seeds with smaller particle size differences are retained on the lower screening component 2. These seeds can ensure the consistency of seed samples when used for hyperspectral imaging quality inspection.

[0040] Working principle: When the seed quality inspection and screening device with hyperspectral imaging is used, the user first puts seeds into the cavity 7 through the feed hopper 16, and uses the upper screening component 2 to screen out seeds with larger particles, so that seeds that meet the particle size fall into the lower screening component 2, and use the lower screening component 2 to screen out seeds with smaller particle sizes, so that seeds with smaller particle sizes pass through the lower screening component 2 and fall into the collection box 14, thereby making seeds with smaller particle size differences trapped on the lower screening component 2, and these seeds are discharged from the equipment box 1 from the lower discharge port 13 and collected so that Hyperspectral imaging quality inspection can ensure the consistency of seed samples. During this process, the output end of the motor 12 drives the rotating shaft 5 to rotate clockwise, and the rotating shaft 5 drives the driving block 6 to rotate clockwise. The driving block 6 drives the extrusion surface 10 to rotate. When the extrusion surface 10 rotates, it intermittently contacts the upper and lower force-bearing surfaces 9 and generates pressure on them, thereby driving the force-bearing rod 4 to move backward. The force-bearing rod 4 drives the screening assembly 2 to move backward to overcome the pressure of the spring 3. When the driving block 6 is separated from the force-bearing rod 4, the spring 3 resets and drives the screening assembly 2 to move, thereby causing the screening assembly 2 to vibrate, thereby improving the screening efficiency.
