[0002] During the harvesting, threshing, and initial processing of rice, problems such as inconsistent rice length, broken rice, and residual impurities can easily occur due to factors such as variety differences, growing environment, and the precision of processing equipment. The rice length grading process, through standardized screening, can accurately separate whole rice that meets the standards, broken rice of different degrees of breakage, and impurities such as rice husks, rice bran, and stones, fundamentally ensuring a high degree of uniformity in the physical characteristics of the same batch of rice.

[0003] Existing rice grading devices use multiple layers of screens to sieve rice. As the core component of the grading device, the screens are easily clogged by impurities, broken rice, and rice husks, affecting their normal sieving function. In addition, the disassembly and cleaning process of the grading device's screens is cumbersome, requiring the use of various tools, which is time-consuming and labor-intensive, reducing production efficiency.

[0004] Therefore, a rice length grading device has been developed that facilitates the disassembly and cleaning of the screen, avoids inaccurate fan operation caused by screen blockage, saves manpower, and improves production efficiency. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] A rice length grading device, such as Figures 1-7 As shown, it includes a first outer shell 1, a second outer shell 2, a first discharge port 3, a second discharge port 4, a first pull pin 5, a first spring 6, a vibrator 7, a second spring 8, a first guide plate 9, a third spring 10, a second guide plate 11, a dustproof assembly, and a mesh guard assembly. The first outer shell 1 is slidably connected to the front of the second outer shell 2, and the first outer shell 1 is connected to the right side of the first outer shell 1 with a first discharge port 3. The lower left side of the first outer shell 1 is connected to the second discharge port 4, and the left and right sides of the first outer shell 1 are slidably connected to two first pull pins 5. The first pull pins 5 are each connected to the first outer shell 1 with a first spring 6, and the first pull pins 5 are each engaged with the second outer shell 2.

[0023] A vibrator 7 is connected to the rear side of the inner side of the first pull pin 5. A first guide plate 9 is slidably connected to the first outer shell 1. A second spring 8 connects the first guide plate 9 to the first outer shell 1. A second guide plate 11 is also slidably connected to the first outer shell 1. Both the first guide plate 9 and the second guide plate 11 are inclined structures, with the second guide plate 11 located above the first guide plate 9. A third spring 10 connects the second guide plate 11 to the first guide plate 9. A dustproof component is provided on the first outer shell 1, and a mesh retainer component is provided on the second guide plate 11.

[0024] like Figure 5 As shown, the dustproof assembly includes a cover 12, a feed inlet 13, connecting blocks 14, and a torsion spring 15. The feed inlet 13 is connected to the upper side of the first outer casing 1. The feed inlet 13 has a bucket-shaped structure, and two connecting blocks 14 are connected to the feed inlet 13 on the left and right. The cover 12 is rotatably connected between the connecting blocks 14, and a torsion spring 15 is connected between each connecting block 14 and the cover 12.

[0025] like Figure 6 and Figure 7 As shown, the mesh clamping assembly includes a screen 16, a second pull pin 17, a fourth spring 18, and a locking block 19. The screen 16 is placed on the second guide plate 11, and the second pull pin 17 is slidably connected to the second guide plate 11. The fourth spring 18 connects the second pull pin 17 to the second guide plate 11, and the locking block 19 is connected to the second pull pin 17. The locking block 19 engages with the screen 16, and the second pull pin 17 has a pull ring for easy pulling.

[0026] When using this utility model, first place the device in the rice length grading area, then pour the rice to be graded into the feed port on the first outer shell 1. The weight of the rice will squeeze the lid 12 to rotate on the connecting block 14, and the torsion spring 15 will deform, causing the lid 12 to tilt. The rice will slide down the lid 12 onto the second guide plate 11. Then, the torsion spring 15 rebounds, causing the cover 12 to close again with the discharge port, preventing dust and impurities from entering the first outer shell 1; at the same time, the vibrator 7 is activated, causing the first guide plate 9 to shake up and down. Under the elastic force of the second spring 8 and the third spring 10, the second guide plate 11 shakes up and down, screening the rice on the second guide plate 11. The more intact rice will be screened out and collected from the first discharge port, while the broken rice will fall onto the first guide plate 9 and then be screened out from the second discharge port 4, thus completing the length grading of the rice. When it is necessary to clean the screen 16, pull the first pull pin 5, the first spring 6 is compressed and contracted, so that the first pull pin 5 is disengaged from the second outer shell 2. Then slide the second outer shell 2 upward, and then pull the second pull pin 17, so that the fourth spring 18 is compressed and contracted, so that the locking block 19 is disengaged from the screen 16, and the screen 16 can be taken out for cleaning. After cleaning, the screen 16 is placed back on the second guide plate 11, and then the second pull pin 17 is released. The fourth spring 18 returns, driving the locking block 19 to reset and lock the screen 16. Then, the second outer shell 2 is slid and closed again with the first outer shell 1. Then, the first pull pin 5 is released, and the first spring 6 returns, so that the first pull pin 5 locks the second outer shell 2. This facilitates the disassembly and cleaning of the screen 16, avoids the inaccuracy of the fan caused by the screen 16 being blocked, and saves manpower and improves production efficiency.
