Abstract
Description
Technical Field
[0001] This utility model relates to the field of cordyceps powder production technology, and in particular to a filtration and sieving device for cordyceps powder production. Background Technology
[0002] Cordyceps powder usually refers to the powder made by drying and grinding Cordyceps sinensis. Cordyceps sinensis is a precious Chinese herbal medicine resource, mainly distributed in high-altitude areas such as Sichuan, Qinghai, and Tibet in China. It is a complex formed by Cordyceps fungus parasitizing the larvae of Lepidoptera insects.
[0003] In the production of cordyceps powder, it is usually filtered and sieved using a sieve frame to obtain powder of the required particle size. However, in existing sieving devices, the sieve frame is usually designed to be fixed to the main body of the equipment, lacking a quick disassembly mechanism. The fixed method of the sieve frame makes it difficult for the operator to separate it from the equipment when cleaning or screen replacement is required. Due to the non-removable nature of the sieve frame, cleaning becomes very difficult when cordyceps powder or other impurities accumulate inside and outside the sieve frame. This results in unsanitary dead corners inside the sieving device that cannot be thoroughly cleaned, increasing the risk of cross-contamination of cordyceps powder during production and affecting the quality and safety of the final product. Utility Model Content

[0023] 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.
[0024] Reference Figure 2 , Figure 3 and Figure 5This utility model provides an embodiment of a filtration and sieving device for producing cordyceps powder, comprising a sieving box 1, a fixed frame 9 slidably connected inside the sieving box 1, a sieve frame 10 disposed inside the fixed frame 9, mounting blocks 11 slidably connected to both sides of the inside of the sieve frame 10, movable blocks 13 fixedly connected to the upper part of each of the mounting blocks 11, handles 14 fixedly connected to the upper part of each of the movable blocks 13, fixed boxes 15 fixedly connected to the upper perimeter of the fixed frame 9, circular plates 18 slidably connected inside each of the fixed boxes 15, one end of a circular rod 17 fixedly connected to the upper part of each of the circular plates 18, a pull plate 16 fixedly connected to the other end of each of the circular rods 17, and insertion rods 19 fixedly connected to the bottom of each of the circular plates 18, with fixed external sides of each of the insertion rods 19. A locking rod 20 is connected, and multiple locking rods 20 are slidably connected inside the mounting block 11. Multiple mounting blocks 11 are slidably connected to both sides of the inside of the fixing frame 9. The inside of multiple fixing frames 9 is provided with cavities. A discharge hopper is fixedly connected to the right side of the screening box 1. Multiple mounting blocks 11 are provided with through holes. Multiple insert rods 19 and locking rods 20 are slidably connected inside the through holes. Multiple insert rods 19 are slidably connected inside the mounting block 11. Multiple insert rods 19 are rotatably connected inside the cavity. Multiple locking rods 20 are rotatably connected inside the cavity. Multiple locking rods 20 are slidably connected inside the cavity. Multiple round rods 17 and insert rods 19 are slidably connected inside the fixing box 15. Springs 2 12 are fixedly connected to the opposite side of multiple mounting blocks 11.
[0025] After the screen frame 10 completes the screening task, the cylinder 2 is activated again, causing the fixed frame 9 to guide the screen frame 10 to slowly move out of the screening box 1. Then, the operator skillfully rotates multiple pull plates 16, causing the round rod 17 and the round plate 18 to rotate skillfully within the fixed box 15. This causes the round plate 18 to rotate, which in turn causes the insertion rod 19 and the locking rod 20 to rotate. The mounting block 11 has a through hole inside. When the insertion rod 19 rotates to be horizontally aligned with the through hole, the operator lifts the pull plate 16, causing the insertion rod 19 and the locking rod 20 to rotate. The 0 is withdrawn from the inner cavity of the mounting block 11, releasing the fixation of the mounting block 11. Immediately afterwards, the operator pulls multiple handles 14, causing the mounting blocks 11 to move, so that multiple mounting blocks 11 come closer to each other, compressing the second spring 12. The second spring 12 is compressed and stores energy. When released, it pushes the mounting blocks 11 to move out of the fixed frame 9. Under the force of the second spring 12, the mounting blocks 11 are moved out of the fixed frame 9 one by one. At this point, the screen frame 10 can be easily pulled out of the fixed frame 9.
[0026] Reference Figure 1 , Figure 2 and Figure 4Cylinders 2 are fixedly connected to both sides of the outer side of the screening box 1. Push plates 3 are fixedly connected to the output ends of the two cylinders 2. Connecting blocks 8 are fixedly connected to the opposite side of the two push plates 3. Fixing frames 9 are fixedly connected to the opposite side of the two connecting blocks 8. Limiting components are fixedly connected to the opposite side of the two push plates 3. The limiting components are used to limit the push plates 3. The limiting components include limiting blocks 4 and limiting rods 6. Multiple limiting blocks 4 are fixedly connected to the opposite side of the two push plates 3. Multiple limiting blocks 4 are slidably connected to the outside of the limiting rods 6. Limiting seats 5 are fixedly connected to the outer perimeter of the screening box 1. Multiple limiting rods 6 are fixedly connected to the inside of the limiting seats 5. Springs 7 are sleeved on the outside of the multiple limiting rods 6. One end of the multiple springs 7 is fixedly connected to the upper part of the limiting blocks 4. The other end of the multiple springs 7 is fixedly connected to the inside of the limiting seats 5.
[0027] The sieve frame 10 is used to hold cordyceps powder and is the direct bearing component of cordyceps powder during the screening process. The cordyceps powder is poured into the sieve frame 10, and then the cylinder 2 is activated. Its output end pushes the push plate 3 forward. As the push plate 3 moves, the limiting block 4 slides back and forth on the outside of the limiting rod 6. When the push plate 3 moves, the limiting block 4 slides on the limiting rod 6, which plays a limiting and guiding role, ensuring the stable movement of the push plate 3. The limiting rod 6 serves as the track for the limiting block 4, ensuring that the limiting block 4 can slide along the predetermined path. When the limiting block 4 moves up and down, the spring 7 is compressed or stretched, which plays a buffering and adjusting role, ensuring the smoothness of the screening process. With the help of the synergistic effect of multiple limiting blocks 4, the push plate 3 guides the connecting block 8 to move. These two connecting blocks 8 move up and down in the screening box 1, thereby driving the fixed frame 9 and the sieve frame 10 to vibrate up and down together inside the screening box 1. The screened cordyceps powder is smoothly discharged through the discharge hopper.
[0028] Working principle: First, the cordyceps powder is poured into the sieve frame 10. Then, the cylinder 2 is started, and the output end of the cylinder 2 pushes the push plate 3 to move. When the push plate 3 moves, it causes the limiting block 4 to slide outside the limiting rod 6. When the limiting block 4 slides up and down, it squeezes or stretches the spring 7. With the cooperation of multiple limiting blocks 4, the push plate 3 drives the connecting block 8 to move. The two connecting blocks 8 move up and down inside the screening box 1, causing the fixed frame 9 and the sieve frame 10 to shake up and down inside the screening box 1, screening the cordyceps powder inside the sieve frame 10. After filtering and screening, the cordyceps powder is discharged out through the discharge hopper, achieving effective filtering and screening of the cordyceps powder. This effectively separates impurities from the cordyceps powder, making the particle size distribution of the cordyceps powder more uniform and improving the homogeneity and stability of the product. After the sieve frame 10 has completed screening, the cylinder 2 is started again, causing the fixed frame 9 to move the sieve frame 10 out of the screening box 1. Then, the operator rotates multiple pull plates 16, which drive the round rod 17 and round plate 18 to rotate inside the fixed box 15. The rotation of the round plate 18 drives the insertion rod 19 and locking rod 20 to rotate. The mounting block 11 has a through hole inside. When the insertion rod 19 rotates to be horizontal with the through hole, the pull plate 16 is pulled up to remove the insertion rod 19 and locking rod 20 from the cavity inside the mounting block 11, releasing the fixing of the mounting block 11. Then, multiple handles 14 are pulled, which drive the mounting blocks 11 to move, so that the multiple mounting blocks 11 are close together and squeeze the second spring 12. Under the action of the second spring 12, the multiple mounting blocks 11 are moved out from inside the fixed frame 9. Next, the screen frame 10 can be pulled out from inside the fixed frame 9, which makes it easy to disassemble the screen frame 10, and it can be easily and thoroughly cleaned to remove residual cordyceps powder and impurities, keep the sieving device hygienic, and avoid cross-contamination.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
