Description

Technical Field

[0001] This utility model relates to the technical field of rice processing equipment, specifically a screening device for organic rice processing. Background Technology

[0002] Organic rice is rich in nutrients such as protein, carbohydrates, vitamins and minerals. Compared with ordinary rice, organic rice has a more balanced nutritional composition and higher content. In the processing of organic rice, screening is a key step, the purpose of which is to remove impurities, broken rice and other contaminants to improve the quality of the rice.

[0003] In the prior art, screening equipment includes a feeding hopper, a screening plate, a discharge mechanism, and a vibration mechanism. The rice to be processed is poured into the feeding hopper, and the rice is continuously jumped and rolled on the screening plate by the vibration mechanism for screening. Finally, the screened rice and impurities are poured out from the corresponding discharge mechanisms.

[0004] However, when rice enters the sieve plate from one end of the feed inlet, it is easy for local accumulation to occur. The accumulated rice cannot fully contact the sieve plate, resulting in poor sieve efficiency. In addition, during sieve operation, impurities and broken rice are easily stuck in the mesh of the sieve plate, causing the mesh to become gradually blocked. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] Please see Figures 1 to 2 This utility model provides a technical solution: a screening device for organic rice processing, including a vibrating device 1, which is equipped with a vibrating motor and connecting components. High-speed rotation generates centrifugal force, causing the screening device to vibrate. A housing 3 is located at the top of the vibrating device 1, and a cover 2 is provided on the surface of the vibrating device 1. A fixing plate 9 is fixedly connected to the inner surface of the vibrating device 1, and a screening plate 5 overlaps the surface of the fixing plate 9. Limiting blocks 11 are slidably connected to both sides of the surface of the fixing plate 9, and the limiting blocks 11 are embedded in the surface of the screening plate 5. A shaft 6 is rotatably connected to the surface of the cover 2. A plate 17 is inserted into the screen plate 5. One end of the plate 17 is fixedly connected to an elastic scraper 7, and the other end of the plate 17 is fixedly connected to a brush 8. The elastic scraper 7 and the brush 8 are attached to the surface of the screen plate 5. By setting a fixing plate 9 inside the housing 3 and setting retractable limiting blocks 11 on both sides of the fixing plate 9 to clamp and fix the screen plate 5, the screen plate 5 can be disassembled and replaced individually, which improves the maintenance efficiency of the equipment. The scraper 7 and the brush 8 on the surface of the screen plate 5 can promote the flow efficiency of rice on the screen plate 5 and can clean the impurities stuck in the screen plate 5 in time, thereby improving the screening efficiency.

[0023] Example 2

[0024] Please see Figures 1 to 3 Based on Embodiment 1, in order to achieve separate disassembly and installation of the screening plate 5, the fixing plate 9 has an annular plate structure with a cross-section of "L". Limiting grooves 12 are opened on both sides of the surface of the fixing plate 9. The limiting grooves 12 are arc-shaped grooves with a cross-section of "T". A rubber block 10 is fixedly connected to the surface of the limiting groove 12. The surface of the limiting block 11 is fixedly connected to the other end of the rubber block 10. The end of the limiting block 11 away from the rubber block 10 is embedded in the annular groove opened on the surface of the screening plate 5. The limiting block 11 has an arc-shaped plate structure. A sliding column 13 is fixedly connected to the surface of the limiting block 11. The height of the sliding column 13 is greater than the groove depth of the upper part of the limiting groove 12.

[0025] The reason for setting up the rubber block 10 is that when the sliding column 13 moves the limiting block 11 to squeeze the rubber block 10, the rubber block 10 changes from its original state to a stretched state, so that the limiting block 11 is retracted in the limiting groove 12. When the sliding column 13 is released, the rubber block 10 has the elasticity to restore its original shape, which moves the limiting block 11 and embeds it in the annular groove on the surface of the screening plate 5.

[0026] Example 3

[0027] Please see Figures 1 to 5 Based on Embodiment 2, in order to push the rice on the surface of the sieve plate 5, a motor 4 is fixedly connected to the center of the surface of the box cover 2. The shaft 6 is connected to the output end of the motor 4. A slot 18 is provided on the surface of the shaft 6 away from the motor 4. The slot 18 consists of two square slots and one round slot. A central rod 14 is fixedly connected to the surface of the slot 18. The central rod 14 has a cylindrical structure and passes through the insert plate 17. A rubber groove 19 is opened on the surface of the central rod 14 away from the slot 18. A rubber strip 16 is fixedly connected to the center of the rubber groove 19. A stop block 15 is fixedly connected to both ends of the rubber strip 16. The stop block 15 has a square block structure. The surfaces of the two stop blocks 15 away from each other have inclined surfaces. The stop blocks 15 press against the surface of the insert plate 17 to limit the position of the insert plate 17.

[0028] One end of the stop block 15 is provided with an inclined surface, which allows the insert plate 17 to apply pressure to the stop block 15 along the inclined surface, thereby causing the stop block 15 to squeeze the rubber strip 16 and retract it into the rubber groove 19.

[0029] In actual use, first, move the sliding columns 13 on both sides of the fixed plate 9 to the opposite ends. The sliding columns 13 drive the limiting block 11 to move and compress the rubber block 10, causing the rubber block 10 to change from its original state to a stretched state. The limiting block 11 retracts into the limiting groove 12. Then, overlap the screening plate 5 on the surface of the fixed plate 9, so that the annular groove on the surface of the screening plate 5 is connected to the limiting groove 12. Release the sliding columns 13, and the rubber block 10 loses the compression and returns to its original state. Slide the limiting block 11 to one end of the annular groove and embed it inside it. Then, move the insert plate 17 along the center... The surface of rod 14 slides, and the insert plate 17 presses against the inclined surface of the stop block 15, causing the stop block 15 to retract into the rubber groove 19. After the insert plate 17 and the surface of the slot 18 are in contact, the rubber strip 16 inside the rubber groove 19 returns to its original state from the compressed state, popping out the stop block 15 and pressing it against the surface of the insert plate 17. Finally, the box cover 2 and the box body 3 are sealed, and rice is poured in from the feed port. The motor 4 drives the shaft 6 to rotate, and the shaft 6 drives the brush 8 and scraper 7 to push the surface of the sieve plate 5 and clean the impurities that clog the mesh on the surface of the sieve plate 5 in a timely manner.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
