Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea seed screening technology, and in particular to an intelligent seed shell screening system. Background Technology
[0002] Camellia oleifera, also known as mountain tea, wild tea, or white flower tea, is a high-quality edible oil plant unique to China. Camellia oleifera and tea (scientific name Camellia sinensis (L.) O. Kuntze) belong to the same genus but different species. The vegetable oil extracted from their seeds is completely different. The former is called camellia seed oil, and the latter is called tea seed oil. Camellia oleifera is a pure natural high-grade edible vegetable oil extracted from the mature seeds of Camellia oleifera, a plant of the Camellia genus in the Theaceae family. More than 90% of the world's camellia seed oil production comes from China.
[0003] Camellia seeds are encased in shells. Before the seeds can be pressed into oil, the shells need to be crushed. Ordinary screening mechanisms cannot completely remove the shells after crushing. Since the shells are of different colors, a color sorter is needed to accurately screen them. However, during the screening process, some shells are broken into smaller or larger pieces. When the shells are removed, the seeds are also removed along with them, resulting in some seeds mixed with the shells after screening. Utility Model Content
[0004] To overcome at least one of the defects described in the prior art, this utility model provides an intelligent seed husk screening system to solve problems such as seed husk mixing.
[0005] The technical solution adopted by this utility model to solve its problem is:
[0006] A seed husk intelligent screening system includes a mounting frame with a conveyor belt. A first color sorter is mounted on the mounting frame at one end of the conveyor belt, and a first sorting bin is located between the first color sorter and the conveyor belt. A feeding mechanism is located above the first color sorter on the mounting frame, and a second color sorter is mounted on the mounting frame at the other end of the conveyor belt. A second sorting bin is located below the second color sorter on the mounting frame.
[0007] The above scheme, using a first color sorter and a second color sorter, allows for precise identification and classification of grains based on color and other optical characteristics. This helps remove foreign objects, damaged products, or products that do not meet quality standards. The system employs a two-stage screening process (first color sorter and second color sorter) to ensure a more detailed classification effect. The first color sorter removes unqualified items, while the second color sorter further filters them.
[0008] Furthermore, the first color sorter is provided with a first screening channel, the upper end of the first sorting barrel is provided with a first inlet, the lower end of the first sorting barrel is provided with a first seed outlet and a first shell outlet, and the first inlet is located below the first screening channel.
[0009] Through the above-mentioned further scheme, the first separation tank separates the seeds and shells from the same batch of screened materials, ensuring that the two products can be clearly distinguished, thereby improving the purity of the product. Through the first seed outlet and the first shell outlet, different types of materials are directed to flow, which facilitates subsequent production processes.
[0010] Furthermore, the first shell outlet is located above one end of the conveyor belt.
[0011] The above-mentioned further method allows the screened shells or seeds to be placed directly on the conveyor belt, thus facilitating the next process.
[0012] Furthermore, the feeding mechanism includes a funnel, a buffer plate, and a sliding plate. A mounting base is fixedly installed on the mounting frame. The funnel, buffer plate, and sliding plate are all fixedly installed on the mounting base. The funnel is located above the buffer plate, and the discharge end of the funnel is located above one end of the buffer plate. The sliding plate is inclined and located below the discharge end of the buffer plate. The bottom end of the sliding plate is located above the first screening channel.
[0013] With the above-mentioned further solution, the funnel is located at the top and can receive and initially collect the material to be screened. Its wide-mouth design can easily accommodate a large amount of material while reducing the risk of blockage during feeding. The material falls from the outlet of the funnel into the buffer plate. The presence of the buffer plate can slow down the falling speed of the material, prevent the material from directly impacting the subsequent equipment, thereby protecting the equipment and ensuring uniform material distribution. The buffer plate can also help disperse the concentrated falling material, making the material more evenly distributed on the slide. The material enters the first screening channel for screening through the slide. The slide helps the material to slide smoothly into the first screening channel, improving the working efficiency and screening accuracy of the color sorter.
[0014] Furthermore, the second color sorter is provided with a second screening channel, the upper end of the second sorting barrel is provided with a second inlet, the lower end of the second sorting barrel is provided with a second seed outlet and a second shell outlet, the second inlet is located below the second screening channel, and the end of the conveyor belt away from the first shell outlet is located above the second screening channel.
[0015] Through the above further scheme, the screened shells or seeds fall directly into the second screening channel via a conveyor belt for secondary screening. The screened shells are discharged from the second shell outlet, and the screened seeds are discharged from the second seed outlet.
[0016] Furthermore, the conveyor belt is provided with several limiting plates.
[0017] The above-mentioned further solutions prevent the grains from rolling and help the materials to be arranged in an orderly manner.
[0018] Furthermore, the mounting frame is equipped with a particle suction cylinder for removing fine particles. The particle suction cylinder is connected to a particle suction head through multiple pipes. The particle suction head is located above the transmission belt and next to the outlet of the first shell.
[0019] With the above-mentioned further solution, the particle suction head is located above the conveyor belt, especially near the first shell outlet, which can effectively remove fine particles and other light impurities discharged from the shell outlet, ensuring that these unwanted materials will not be mixed back into the materials being processed, improving the purity of the final product, and also removing dust to ensure the quality of the air in the working environment.
[0020] Furthermore, a conveyor platform is provided next to the mounting frame, with one end of the conveyor platform located below the second seed outlet and the other end located above the funnel.
[0021] Through the above-mentioned further scheme, the grains selected in the second screening are conveyed to the funnel via a conveyor, and then screened again by the first color sorter to ensure that the qualified grains can be transferred to the next stage for processing.
[0022] In summary, the intelligent seed husk screening system provided by this utility model has the following technical effects:
[0023] 1. Through the first and second color sorters, the seeds can be accurately identified and classified according to color and other optical characteristics, efficiently sorting out healthy tea seeds, effectively removing tea seed shells, moldy seeds, bad seeds, insect-bitten seeds, broken seeds, foreign objects and other impurities, and helping to remove foreign objects and other products that do not meet quality standards.
[0024] 2. The system employs a two-stage screening process (first color sorter and second color sorter) to ensure more detailed classification. The first color sorter removes unqualified items, while the second color sorter further filters out unqualified items, ensuring that the seeds are not mixed in large quantities with the shells.

[0033] Example:
[0034] refer to Figure 1 and Figure 2 As shown, a seed and shell intelligent screening system includes a mounting frame 1, on which a conveyor belt 11 is mounted. A first color sorter 2 is mounted on the mounting frame 1 at one end of the conveyor belt 11. A first separating barrel 3 is located on the mounting frame 1 between the first color sorter 2 and the conveyor belt 11. The first color sorter 2 has a first screening channel 21. The first separating barrel 3 has a first inlet 31 at its upper end and a first seed outlet 32 and a first shell outlet 33 at its lower end. The first inlet 31 is located below the first screening channel 21. The first separating barrel 3 separates seeds and shells from the same batch of screened materials, ensuring that the two products can be clearly distinguished, thereby improving the purity of the product. The first seed outlet 32 and the first shell outlet 33 guide the flow of different types of materials, facilitating subsequent production processes. The first shell outlet 33 is located above one end of the conveyor belt 11, allowing the screened shells or seeds to be placed directly on the conveyor belt 11.
[0035] It should be noted that a transmission mechanism for conveying the seed to the next stage is provided at the first seed outlet 32.
[0036] A mounting base 12 is fixedly mounted on the mounting frame 1. A funnel 41, a buffer plate 42, and a sliding plate 43 are fixedly mounted on the mounting base 12. The funnel 41 is located above the buffer plate 42, and the discharge end of the funnel 41 is located above one end of the buffer plate 42. The sliding plate 43 is inclined and located below the discharge end of the buffer plate 42. The bottom end of the sliding plate 43 is located above the first screening channel 21. The funnel 41 is located at the top and can receive and initially collect the material to be screened. Its wide-mouth design can easily accommodate a large amount of material. To reduce the risk of clogging during feeding, the material falls from the discharge end of the funnel 41 into the buffer plate 42. The presence of the buffer plate 42 can slow down the falling speed of the material, prevent the material from directly impacting the subsequent equipment, thereby protecting the equipment and ensuring uniform material distribution. In addition, the buffer plate 42 can help disperse the concentrated falling material, making the material more evenly distributed on the slide plate 43. The material enters the first screening channel 21 for screening through the slide plate 43. The slide plate 43 helps the material to slide smoothly into the first screening channel 21, improving the working efficiency and screening accuracy of the color sorter.
[0037] A second color sorter 5 is installed on the mounting frame 1 at the other end of the conveyor belt 11. A second sorting barrel 6 is provided on the mounting frame 1 below the second color sorter 5. The second color sorter 5 is provided with a second screening channel 51. A second feed inlet 61 is provided at the upper end of the second sorting barrel 6. A second seed outlet 62 and a second shell outlet 63 are provided at the lower end of the second sorting barrel 6. The second feed inlet 61 is located below the second screening channel 51. The end of the conveyor belt 11 away from the first shell outlet 33 is located above the second screening channel 51. The shells or seeds that are screened fall directly into the second screening channel 51 through the conveyor belt 11 for secondary screening. The shells that are screened are discharged from the second shell outlet 63, and the seeds that are screened are discharged from the second seed outlet 62.
[0038] refer to Figure 3 As shown, a conveyor 8 is provided next to the mounting frame 1. One end of the conveyor 8 is located below the second seed outlet 62, and the other end is located above the funnel 41. The seeds selected in the second screening are conveyed into the funnel 41 through the conveyor 8 and then screened again by the first color sorter 2 to ensure that the qualified seeds after screening can be transferred to the next stage for processing.
[0039] The conveyor belt 11 is provided with several limiting plates 111, which prevent the grains from rolling and help the materials to be arranged in an orderly manner.
[0040] It should be noted that both the first color sorter 2 and the second color sorter 5 use color to screen seed shells. When the seeds and shells are close to or in contact with each other, some seeds may be mistakenly selected into the shells.
[0041] It should be noted that this system can be expanded to include multiple color sorters, which can perform multiple screenings on the shells after screening to ensure that all the grains can be screened out.
[0042] The mounting frame 1 is equipped with a particle suction cylinder 7 for removing fine particles. The particle suction cylinder 7 is connected to a particle suction head 71 through multiple pipes. The particle suction head 71 is located above the conveyor belt and next to the first shell outlet 33. The particle suction head 71 is located above the conveyor belt 11, especially near the first shell outlet 33, which can effectively remove fine particles and other light impurities discharged from the shell outlet, ensuring that these unwanted materials will not be mixed back into the material being processed, improving the purity of the final product, and also removing dust to ensure the quality of the air in the working environment.
[0043] One end of the particle suction cylinder 7 is connected to the external dust discharge channel.
[0044] In particular, after the particle suction cylinder 7 removes fine particles, the color sorter can more accurately identify and classify the grains without being disturbed by small impurities, thereby improving the accuracy and efficiency of screening.
[0045] The working principle of this utility model is as follows:
[0046] S1. Place the seed shell mixture into funnel 41;
[0047] S2. The seed husk mixture enters the slide plate 43 through the buffer plate 42. The slide plate 43 is tilted so that the seed husk mixture slides down obliquely in the slide plate 43 and then passes through the first screening channel 21.
[0048] S3. The first screening channel 21 screens the passing seed-husk mixture, so that the seeds are discharged from the first seed outlet 32, and the seed-husk mixture after the first screening is discharged from the first shell outlet 33.
[0049] S4. The seed-shell mixture after the first screening is discharged from the first shell outlet 33 onto the conveyor belt 11, and through the conveyor belt 11, the seed-shell mixture after the first screening passes through the second screening channel 51.
[0050] S5. The second screening channel 51 screens the mixture of seeds and shells after the first screening, so that the seeds are discharged from the second seed outlet 62 and the shells are discharged from the second shell outlet 63.
[0051] S6. The seeds discharged from the second seed outlet 62 are conveyed through the conveyor 8 into the funnel 41 for screening again.
[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
