Description

Technical Field

[0001] This utility model relates to the technical field of screening devices, and more specifically, to a buckwheat screening device. Background Technology

[0002] Buckwheat is rich in rutin and other polyphenolic compounds, possessing antioxidant, antitumor, blood pressure-lowering, blood sugar-lowering, and blood lipid-lowering activities. It is an important crop with abundant medicinal and nutritional value.

[0003] The most common edible part of buckwheat is the buckwheat seed. After harvesting, it cannot be directly processed, crushed, or packaged because buckwheat seeds contain a large number of small stones, empty shells, and other impurities. Furthermore, some products are sorted according to seed size to improve the appearance of the final packaged product. Therefore, buckwheat seeds need to be screened to remove impurities and empty shells. They are then sorted by seed size before undergoing further processing and packaging. However, the process of removing impurities and screening buckwheat requires multiple pieces of equipment, and the buckwheat seeds need to be transferred between these machines, resulting in high costs and being time-consuming and labor-intensive. Utility Model Content

Detailed Implementation

[0018] Example The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 -Appendix Figure 4As shown, the buckwheat screening device of this embodiment includes a storage tank 11 with an open top, a conical screen plate 21 at the upper end of the storage tank 11, annular first screening area 22, second screening area 23 and third screening area 24 on the screen plate 21, a feed pipe 34 vertically arranged above the screen plate 21 and within the first screening area 22, a receiving box 12 in the storage tank 11, and an annular partition 14 in the storage tank 11; the first screening area 22 is located near the middle of the screen plate 21, the third screening area 24 is located at the edge of the screen plate 21, and the second screening area 23 is located between the first screening area 22 and the second screening area 23; the side wall of the receiving box 12 is located between the first screening area 22 and the second screening area 23, and the side wall of the partition 14 is located between the second screening area 23 and the third screening area 24; the apertures of the first screening area 22, the second screening area 23 and the third screening area 24 increase sequentially; a gap is provided between the feed pipe 34 and the screen plate 21. Specifically, during use, buckwheat grains are fed into the feed pipe 34 and fall onto the sieve plate 21. Since the sieve plate 21 has a conical structure, the buckwheat grains slide down it. During this sliding process, they first pass through the first screening zone 22, where small impurities and stones fall into the receiving box 12 below. Then, the small grains pass through the second screening zone 23 and fall into the partition 14 of the storage bin 11. Larger grains pass through the third screening zone 24 and fall into the area between the partition 14 and the wall of the storage bin 11. This process not only separates small impurities from the buckwheat but also separates large and small grains, effectively improving production efficiency. Furthermore, the entire process is highly automated, effectively reducing the labor intensity of workers. The first screening zone 22, the second screening zone 23, and the third screening zone 24 are areas with densely packed sieve holes of different diameters.

[0019] In this embodiment, the upper end of the receiving box 12 is located near the sieve plate 21, and the lower end of the receiving box 12 is provided with multiple support rods 13, the lower ends of which are mounted on the bottom of the storage bucket 11. Specifically, considering that the impurity content in buckwheat is not high, a small-capacity receiving box 12 is sufficient. Since small buckwheat particles that pass through the second sieve zone 23 constitute the majority of buckwheat, the height of the receiving box 12 is reduced, and the receiving box 12 is supported by the support rods 13, so that the space at the lower end of the receiving box 12 can be used to accommodate small buckwheat particles.

[0020] In this embodiment, the storage bin 11 is provided with a first discharge pipe 15 and a second discharge pipe 16 at its bottom. The first discharge pipe 15 is located directly below the receiving box 12, and the second discharge pipe 16 is located between the partition plate 14 and the side wall of the storage bin 11. Specifically, the buckwheat particles in the storage bin 11 can be discharged through the first discharge pipe 15 and the second discharge pipe 16. In addition, multiple retractable support columns 17 can be provided at the lower end of the storage bin 11. After a batch of buckwheat is processed, the height of the storage bin 11 can be lowered through the support columns 17, thereby removing the storage bin 11 from under the sieve plate 21 for thorough cleaning.

[0021] In this embodiment, a drive device 30 is also included to drive the sieve plate 21 to rotate around its axis. The drive device 30 includes a support 31 mounted on the ground, a motor 32 mounted on the support 31, and a drive rod 33 mounted on the output shaft of the motor 32; the drive rod 33 is fixedly connected to the middle of the sieve plate 21; and the feed pipe 34 is fixedly mounted on the support 31. Specifically, the motor 32 drives the drive rod 33 to rotate, which in turn drives the sieve plate 21 to rotate. During the rotation of the sieve plate 21, the movement of buckwheat particles on the sieve plate 21 can be promoted, preventing them from clogging.

[0022] In this embodiment, the feed pipe 34 has a guide pipe 35 on its side wall. Specifically, buckwheat granules are fed into the feed pipe 34 through the guide pipe 35.

[0023] In this embodiment, the sieve plate 21 has an annular first groove 25 and an annular second groove 26 on its lower side; the upper end of the receiving box 12 is located in the first groove 25, and the upper end of the partition plate 14 is located in the second groove 26. Specifically, this can better restrict the sieve plate 21, making the sieve plate 21 rotate more smoothly.

[0024] In this embodiment, a pressurizing device 40 connected to the storage bin 11 is also included. The pressurizing device 40 includes a first jet pipe 41 disposed inside the partition 14, a plurality of first nozzles 42 disposed on the first jet pipe 41, a second jet pipe 43 disposed between the partition 14 and the wall of the storage bin 11, a plurality of second nozzles 44 disposed on the second jet pipe 43, a conduit 45 connected to both the first jet pipe 41 and the second jet pipe 43, and an air compressor connected to the conduit 45. Both the first nozzles 42 and the second nozzles 44 are arranged downwards. Specifically, air is injected into the conduit 45 by an air compressor and sprayed out from the first nozzle 42 and the second nozzle 44. After filling the storage tank 11, the air is sprayed out from the sieve holes of the first sieve zone 22, the second sieve zone 23 and the third sieve zone 24. The airflow sprayed out from the sieve holes will not affect the passage of buckwheat particles through the sieve holes. However, for impurities such as empty buckwheat hulls, they will not be able to pass through the sieve holes due to the resistance of the airflow and will eventually roll off the edge of the sieve plate 21. This can effectively remove the empty hulls from the buckwheat.

[0025] In this embodiment, the outer edge of the sieve plate 21 is at the same height as the upper end of the storage bucket 11; a gap is provided between the edge of the sieve plate 21 and the upper end of the storage bucket 11, and the width of the gap is greater than or equal to the aperture of the third sieve area 24. Specifically, the gap facilitates the entry of ultra-large buckwheat particles into the storage bucket 11, and air is also blown out through the gap, preventing empty shells from passing through.

[0026] In summary, the buckwheat screening equipment of this embodiment feeds buckwheat particles into the feed pipe 34 and drops them onto the screen plate 21. Since the screen plate 21 has a conical structure, the buckwheat particles slide down the screen plate 21. During the sliding process, they first pass through the first screening zone 22. Small particles, impurities, stones, etc. in the buckwheat pass through the first screening zone 22 and fall into the receiving box 12 below. Then, the small particles in the buckwheat pass through the second screening zone 23 and fall into the partition 14 of the storage tank 11. The large particles in the buckwheat pass through the third screening zone 24 and fall into the area between the partition 14 and the wall of the storage tank 11. In this way, not only can small particles and impurities in the buckwheat be separated, but also large and small buckwheat particles can be separated, which can effectively improve production efficiency. Moreover, the whole process has a high degree of automation, which can effectively reduce the labor intensity of workers.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
