Description

Technical Field

[0001] This utility model relates to the field of food production technology, specifically a multi-stage screening device for watermelon seed kernel production. Background Technology

[0002] Watermelon seeds are food ingredients obtained from watermelon seeds after being processed through washing, drying, and shelling. They are rich in unsaturated fatty acids, protein, cellulose, and various vitamins and minerals, and have a unique taste and nutritional value. Screening devices used in watermelon seed production can be used to remove impurities such as dust, broken shells, and small stones from the watermelon seeds, ensuring the purity and yield of the product.

[0003] Existing screening devices typically screen watermelon seed kernels using a sieve plate. However, this process involves a limited number of screenings, resulting in some impurities or defective seeds not being removed. This negatively impacts the overall quality and taste of the product, as well as production efficiency, product quality, and production flexibility. Furthermore, the limited number of screenings significantly reduces the grading effect, leading to uneven particle size distribution in the final product and affecting its appearance and quality.

[0004] Therefore, it is necessary to provide a new multi-stage screening device for watermelon seed kernel production to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage screening device for watermelon seed kernel production, so as to solve the problems mentioned in the background art.

[0024] Please see Figure 1-5 As shown, a multi-stage screening device for watermelon seed kernel production includes a housing 1, a mounting frame 2 disposed within the cavity of the housing 1, a support plate 3 slidably connected to the inner wall of the mounting frame 2, a storage box 4 mounted on the top of the support plate 3, and a screening box 11 for screening watermelon seed kernels mounted on the top of the storage box 4. Multiple sets of screening boxes 11 can be installed on the storage box 4, and different numbers of screening boxes 11 can be installed according to different screening times. A mounting base 5 is fixedly connected to the inner wall of the housing 1, a connecting frame 6 is fixedly connected to one side of the mounting base 5, a support plate 7 is disposed on one side of the connecting frame 6, a guide rod 8 is fixedly connected to one side of the support plate 7, a guide frame 9 is slidably connected to the outer side of the guide rod 8, and a fixed rod 10 is fixedly connected to the top of the guide frame 9. The rotation of the support plate 7 drives the guide rod 8 to rotate, and the guide rod 8 pulls the guide frame 9 to move, so that the fixed rod 10 contacts the support plate 3. The vibrating screening box 11 vibrates to screen watermelon seed kernels. A fixed frame 12 is fixed to the outside of the storage box 4 and the screening box 11. A limiting frame 13 is snapped into the inner wall of the fixed frame 12. An installation block 14 for installing the storage box 4 and the screening box 11 is fixedly connected to one side of the limiting frame 13. An installation bolt 15 is threaded into the inner wall of the installation block 14. The limiting frame 13 is installed on the outside of the storage box 4 by inserting the limiting frame 13 into the fixed frame 12. Then, the fixed frame 12 on the outside of the screening box 11 is placed on the outside of the limiting frame 13, so that the fixed frame 12 is snapped into the outside of the installation block 14. The installation block 14 and the fixed frame 12 are installed by the installation bolt 15, thereby installing the screening box 11. Multiple sets of screening boxes 11 can be installed on the storage box 4. Different numbers of screening boxes 11 can be installed according to different screening times, thereby performing multi-stage screening of watermelon seed kernels.

[0025] A drive motor 16 is mounted on one side of the mounting base 5. A drive rod 17, which drives the support plate 7 to rotate, is fixedly connected to the output end of the drive motor 16. One end of the drive rod 17 is fixedly connected to one side of the support plate 7. A limit rod 18 is fixedly connected to the inner wall of the connecting frame 6. A limit sleeve 19, which limits the guide frame 9, is slidably connected to the outer side of the limit rod 18. The limit sleeve 19 is fixed to the outer side of the guide frame 9. A connecting plate 20 is fixedly connected to the inner wall of the housing 1. A guide rod 21, which limits the support plate 3, is fixedly connected to one side of the connecting plate 20. The outer side of the guide rod 21 is slidably connected to the inner wall of the mounting frame 2. A spring 22 is provided on the outer side of the guide rod 21. The drive motor 16 drives the drive rod 17 and the support plate 7 to rotate. The rotation of the support plate 7 drives the guide rod 8 to rotate. The guide rod 8 pulls the guide frame 9 to move, so that the fixed rod 10 contacts the support plate 3. This causes the storage box 4 and the screening box 11 to vibrate, thus vibrating and screening the watermelon seed kernels. The screened watermelon seed kernels remain inside the screening box 11. Through multiple screenings, impurities such as dust, broken shells, and small stones in the watermelon seed kernels finally fall into the storage box 4. The fixed rod 10 drives the mounting frame 2 to slide outside the guide rod 21, causing the spring 22 to contract. The spring 22 then drives the mounting frame 2 and the support plate 3 to reset, improving the screening effect of the watermelon seed kernels.

[0026] A limiting seat 23 is fixedly connected to the outer side of the limiting frame 13. The inner wall of the limiting seat 23 is slidably connected to the outer side of the fixed frame 12. The limiting seat 23 improves the stability of the fixed frame 12. A door 24 is provided on one side of the box body 1. A viewing window 25 is provided on one side of the door 24. A ventilation opening 26 is provided on one side of the door 24. An installation frame 27 is fixedly connected to one side of the door 24. A filter screen 28 is slidably connected to the inner wall of the installation frame 27. The filter screen 28 adsorbs the screening dust and reduces air pollution caused during screening.

[0027] Working principle: In use, the limiting frame 13 is inserted into the fixed frame 12, and the limiting frame 13 is installed on the outside of the storage box 4. Then, the fixed frame 12 on the outside of the screening box 11 is placed on the outside of the limiting frame 13, so that the fixed frame 12 is locked on the outside of the mounting block 14. The mounting block 14 and the fixed frame 12 are installed by the mounting bolts 15, thereby installing the screening box 11. Multiple sets of screening boxes 11 can be installed on the storage box 4, and different numbers of screening boxes 11 can be installed according to different screening times, so as to perform multi-stage screening of watermelon seed kernels. The drive motor 16 drives the drive rod 17 and the support. The support plate 7 rotates, which drives the guide rod 8 to rotate. The guide rod 8 pulls the guide frame 9 to move, causing the fixed rod 10 to contact the support plate 3. This causes the storage box 4 and the screening box 11 to vibrate, thus screening the watermelon seed kernels. The screened watermelon seed kernels remain inside the screening box 11. Through multiple screenings, impurities such as dust, broken shells, and small stones in the watermelon seed kernels finally fall into the storage box 4. The fixed rod 10 drives the mounting frame 2 to slide outside the guide rod 21, causing the spring 22 to contract. The spring 22 then drives the mounting frame 2 and the support plate 3 to reset, improving the screening effect of the watermelon seed kernels.
