Description

Technical Field

[0001] This utility model relates to the field of camellia fruit processing technology, specifically a preliminary sorting system for seed shells after the camellia fruit is popped and separated. Background Technology

[0002] During the processing of camellia oleifera fruit, the outer husk must first be removed using a popping and separating process, resulting in a mixture of camellia seeds and inner husks. The mixture after popping and separating contains camellia seeds of various sizes, including small, medium, and large seeds, and the husks also vary in shape, such as small and medium husks, depending on the degree of breakage. Before proceeding to subsequent oil pressing or further processing stages, the seeds and husks must be separated to ensure the processing conversion rate of the camellia seeds and the quality of the final product.

[0003] In existing technologies, most equipment for separating seed shells after the fruit of Camellia oleifera has burst open uses a single screening structure, such as a single-layer filter screen separator. This can only achieve simple separation of seed shells and is prone to problems such as mixing of small and medium-sized seeds with medium-sized shells and the inability to effectively separate large seeds with large shells. This results in insufficient purity of the sorted material and affects subsequent processing. Utility Model Content

[0004] The purpose of this invention is to provide a preliminary sorting system for seed shells after the fruit and seed shells of Camellia oleifera are separated.

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] refer to Figure 1-4 A preliminary sorting system for seed shells after the separation of Camellia oleifera fruit and seed husks includes a fixed base 1, a drive structure 2, and a sorting structure 3. The fixed base 1 serves as the installation reference and support carrier for the system, providing a stable installation platform for the drive structure 2, the sorting structure 3, and subsequent auxiliary structures, ensuring that each component maintains a fixed relative position during operation. The drive structure 2 provides a power source for the rotation of the sorting structure 3, enabling the gradual sorting of the mixture after the separation of Camellia oleifera fruit and seed husks.

[0018] The sorting structure 3 adopts a coaxial series structure to form a continuous annular sorting channel, ensuring that materials can move orderly along the channel and complete grading and screening. The sorting structure 3 includes an active ring 31, a first sorting ring 32, a second sorting ring 33, a third sorting ring 34, a fourth sorting ring 35, and a driven ring 36. The active ring 31 is rotatably mounted on one side of the fixed base 1 and connected to the drive structure 2. It can receive the power transmitted by the drive structure 2 and synchronously transmit the power to the subsequent sorting rings, driving the entire sorting structure 3 to rotate stably. The inner diameter of the active ring 31 can be precisely matched with the outer diameter of the first sorting ring 32. It can be fixed to the first sorting ring 32 by welding or high-strength bolts to ensure that there is no loosening or slippage during power transmission and to ensure the synchronicity of the rotation of the sorting structure 3. The first sorting ring 32 is coaxially mounted on one side of the active ring 31 and is the first-stage sorting component after the material enters the sorting channel. It is used for preliminary screening of small-sized fruit shells in the mixed materials. The second sorting ring 33 is coaxially located on the side of the first sorting ring 32 away from the active ring 31. It receives the material after being screened by the first sorting ring 32 and can separate small and medium-sized camellia seeds from some medium-sized shells. The third sorting ring 34 is coaxially located on the side of the second sorting ring 33 away from the first sorting ring 32 and can screen out medium-sized shells from the material retained by the second sorting ring 33. The fourth sorting ring 35 is coaxially located on the side of the third sorting ring 34 away from the second sorting ring 33 and can separate large-sized camellia seeds from the remaining shells. The driven ring 36 is located on the side of the fourth sorting ring 35 away from the third sorting ring 34 and can be rotatably mounted on the fixed base 1. The inner diameter of the driven ring 36 is precisely matched with the outer diameter of the fourth sorting ring 35 and can be fixed to the fourth sorting ring 35 by welding or high-strength bolts. It can form symmetrical support with the active ring 31 to ensure that the entire sorting structure 3 maintains coaxiality during rotation and avoids eccentric rotation caused by unilateral force. An additional collection structure can be set outside the driven ring 36 to collect large-sized fruit shells. This is existing technology and will not be described in detail here.

[0019] In some embodiments, the first sorting ring 32 is provided with a plurality of first strip-shaped holes at equal intervals, and the third sorting ring 34 is provided with a plurality of second strip-shaped holes at equal intervals. The strip-shaped holes can adapt to the flat shape of the fruit shell. The design of the size of the strip-shaped holes facilitates the passage of the corresponding fruit shell, while achieving the interception of the corresponding size of camellia seeds. The second sorting ring 33 is provided with a plurality of first round holes at equal intervals, and the fourth sorting ring 35 is provided with a plurality of second round holes at equal intervals. The design of the round holes can better match the spherical shape of the camellia seeds and ensure that the camellia seeds pass through smoothly.

[0020] In some embodiments, the width of the first strip hole is smaller than the width of the second strip hole, ensuring that the first sorting ring 32 only filters small-sized fruit shells and the third sorting ring 34 filters medium-sized fruit shells, thus avoiding functional confusion in the fruit shell screening process. The diameter of the first round hole is smaller than the diameter of the second round hole, ensuring that the second sorting ring 33 filters small-to-medium-sized camellia seeds and the fourth sorting ring 35 filters large-sized camellia seeds, thereby achieving size grading of camellia seeds.

[0021] In some embodiments, the width of the first strip hole can be 7-7.5mm to accurately screen out small-sized fruit shells with a thickness of less than 7mm, while preventing the smallest-sized camellia seeds with a diameter of ≥8mm from passing through, ensuring the accuracy of the first-stage sorting. The width of the second strip hole can be 12-12.5mm to specifically screen out medium-sized fruit shells with a thickness of less than 12mm, while large-sized camellia seeds with a diameter of 25-30mm and large-sized fruit shells with a width of ≥15mm cannot pass through, achieving accurate removal of medium-sized fruit shells.

[0022] In some embodiments, the diameter of the first circular hole can be 24 mm. This size ensures that small and medium-sized camellia seeds with a diameter of 18-22 mm (accounting for more than 90% of the total seed quantity) can pass through smoothly. Although the thickness of the medium-sized shell is less than 24 mm, its length is greater than 24 mm. In this case, the medium-sized shell can only pass through the first circular hole quickly when its length is parallel to the central axis of the first circular hole, thus achieving the shell falling off. During the movement of the shell in the second sorting ring 33, the number of such shells is very small. Therefore, the screened camellia seeds will only be mixed with a small amount of medium-sized shells, thereby achieving the initial separation of small and medium-sized seeds from large seeds and large shells. The diameter of the second circular hole can be 30 mm. This size matches the maximum diameter of large-sized camellia seeds of about 30 mm, ensuring that the remaining 10% of large-sized camellia seeds can pass through smoothly, while large-sized shells with a diameter greater than 30 mm or irregular shape are intercepted, completing the separation of large seeds from the remaining shells.

[0023] More specifically, the second sorting ring 33 has a first circular hole with a diameter of 24 mm. This size is highly compatible with the spherical shape of small and medium-sized camellia seeds (18-22 mm in diameter), allowing them to easily pass through the hole and fall into the hopper below during rotation. In contrast, medium-sized shells are mostly flat or irregularly shaped. Although their thickness may be less than 24 mm, their overall dimensions, such as length and width, are much greater than 24 mm. Only in rare cases can medium-sized shells pass through when they contact the circular hole perpendicularly to the screen surface. Therefore, the vast majority of medium-sized shells are effectively retained along with larger seeds and shells, continuing to move to the next stage, thus achieving high-purity separation of small and medium-sized seeds.

[0024] In some embodiments, a rotating structure 4 is further included. The rotating structure 4 includes two first rotating seats 41, two second rotating seats 42, two first rotating wheels 43, and two second rotating wheels 44. The two first rotating seats 41 are symmetrically arranged on the side of the fixed seat 1 near the driving ring 31. They can be made of cast iron and can be fixed to the fixed seat 1 by high-strength bolts. The top is provided with an arc-shaped groove adapted to the first rotating wheel 43, which can provide a stable installation and rotation space for the first rotating wheel 43 and prevent axial displacement of the first rotating wheel 43. The two second rotating seats 42 can be symmetrically arranged on the side of the fixed seat 1 near the driven ring 36. They are also made of cast iron and can be fixed to the fixed seat 1 by high-strength bolts. The first rotating seat 41 is fixed, and the top is provided with an arc-shaped groove that matches the second rotating wheel 44, providing stable support for the second rotating wheel 44. The first rotating wheel 43 is rotatably disposed in the arc-shaped groove of the first rotating seat 41 and can be rotatably connected by bearings. The outer circumferential surface can be provided with an annular protrusion that matches the annular groove on the outer circumferential surface of the active ring 31. Through the cooperation of the groove and the protrusion, the first rotating wheel 43 and the active ring 31 are rolled together to avoid relative sliding. One of the first rotating wheels 43 is connected to the drive structure 2 to receive power and drive the active ring 31 to rotate through rolling friction. The other first rotating wheel 43 plays an auxiliary support role to ensure that the active ring 31 is subjected to uniform force and prevent deformation caused by unilateral force. The second rotating wheel 44 is rotatably disposed in the arc-shaped groove of the second rotating seat 42 and can be rotatably connected by bearings. The outer circumferential surface is provided with an annular protrusion that matches the annular groove on the outer circumferential surface of the driven ring 36. Through the cooperation of the groove and the protrusion, the second rotating wheel 44 and the driven ring 36 are rolled together. Both second rotating wheels 44 are auxiliary support components, forming a symmetrical support structure with the first rotating wheel 43, and together ensuring the coaxial rotation of the sorting structure 3.

[0025] In some embodiments, the drive structure 2 adopts a sprocket drive to ensure the stability and efficiency of power transmission. It includes a drive motor 21, a main sprocket 22, a driven sprocket 23, and a chain 24. The drive motor 21 is located on the side of the fixed base 1 near the first rotating base 41. It can be a three-phase asynchronous motor and can be fixed to the fixed base 1 by a motor bracket. The main sprocket 22 is coaxially sleeved on the output shaft of the drive motor 21 and can be fixed to the output shaft by a flat key to ensure synchronous rotation with the drive motor 21. The driven sprocket 23 is coaxially connected to one of the first rotating wheels 43 and can be fixed to the shaft of the first rotating wheel 43 by a flat key. The chain 24 is connected to the main sprocket 22 and the driven sprocket 23. The pitch of the chain 24 is precisely matched with that of the main sprocket 22 and the driven sprocket 23. The stable transmission of power from the main sprocket 22 to the driven sprocket 23 is achieved through chain meshing, thereby driving the first rotating wheel 43 and the sorting structure 3 to rotate. The drive connection between chain 24, main sprocket 22, and driven sprocket 23 ensures that the sorting structure 3 rotates at a suitable speed, guaranteeing sufficient time for the material to pass through the screen holes while preventing material splashing or incomplete sorting due to excessive rotation speed. In some embodiments, the system further includes four hoppers 5, which are respectively located below the first sorting ring 32, the second sorting ring 33, the third sorting ring 34, and the fourth sorting ring 35. The hopper 5 below the first sorting ring 32 is used to collect the small shells that have been screened out. The hopper 5 below the second sorting ring 33 is used to collect more than 90% of the small and medium-sized seeds and some shells that have been screened out. The hopper 5 below the third sorting ring 34 is used to collect the medium-sized fruit shells that have been retained, and its collection volume accounts for about 30% of the total medium-sized fruit shells in the mixture. The hopper 5 below the fourth sorting ring 35 is used to collect the remaining 10% of the large seeds and some shells. The hoppers 5 can be made of stainless steel and have a funnel-shaped structure. The size of the top opening is consistent with the size of the corresponding sorting ring, ensuring that all the material screened out by the sorting ring can fall into the hopper 5 without scattering. Each hopper 5 has a discharge port at the bottom, and the discharge port is equipped with a manual or electric valve, which can flexibly control the discharge rate according to the material collection volume, facilitating the subsequent transfer of the classified material to the next processing stage.

[0026] The specific working principle is as follows: The operator starts the drive motor 21, causing the main sprocket 22 to rotate synchronously. The main sprocket 22 transmits power to the driven sprocket 23 via the chain 24. The driven sprocket 23 drives the first rotating wheel 43, which is coaxially connected to the first rotating wheel 43, to rotate. The annular protrusion on the outer circumference of the first rotating wheel 43 matches the annular groove on the outer circumference of the driving ring 31, and drives the driving ring 31 to rotate synchronously through a rolling connection. At the same time, the first rotating wheel 43 on the other side provides auxiliary support to ensure that the driving ring 31 is subjected to uniform force. The two second rotating wheels 44 on one side of the driven ring 36 roll synchronously in the arc-shaped groove of the second rotating seat 42 when the driven ring 36 rotates with the sorting structure 3, forming symmetrical support with the driving ring 31 and ensuring that the sorting structure 3 starts to rotate with stable coaxiality. Once the sorting structure 3 rotates at a stable speed, the mixture of seed shells and husks after the separation of camellia fruit and husks is fed into the annular sorting channel of the sorting structure 3 from the active ring 31 side. Under the combined action of centrifugal force and gravity, the material moves orderly along the channel towards the driven ring 36 side, passing through four sorting rings to complete the grading and sorting. It is understood that, to ensure a more ideal sorting effect, in this application, the rotational speed of the drive structure 2 driving the sorting structure 3 is preferably controlled within the range of 15-25 rpm. In actual production, it was found that excessively high rotational speeds cause the material to adhere tightly to the inner wall, making it difficult to pass through the sieve holes; excessively low rotational speeds affect processing efficiency. Furthermore, to utilize gravity to assist the material in moving orderly along the sorting channel, the fixed base 1 allows the entire sorting structure 3 to be installed at a slight inclination angle of 3-8 degrees, making the active ring 31 side slightly higher than the driven ring 36 side.

[0027] The material first reaches the area of ​​the first sorting ring 32. The first sorting ring 32 has first strip-shaped holes with a width of 7-7.5mm at equal intervals. The size of these strip-shaped holes is adapted to the shape characteristics of small, flat fruit shells with a thickness of less than 7mm. Under the rotation of the sorting structure 3, the small fruit shells in the mixture are thrown towards the inner wall of the first sorting ring 32 under the action of centrifugal force, and then fall into the corresponding hopper 5 below through the first strip-shaped holes; while the smallest size camellia seeds with a diameter ≥8mm and larger fruit shells cannot be intercepted by the first strip-shaped holes and continue to move with the channel to the second sorting ring 33, completing the precise screening of small fruit shells.

[0028] The material after the first-stage screening enters the second sorting ring 33 area. The second sorting ring 33 has evenly spaced first circular holes with a diameter of 24mm. The size of these holes is highly compatible with the spherical shape of small and medium-sized camellia seeds (18-22mm in diameter). Under the centrifugal force generated by rotation and the material's own gravity, the small and medium-sized camellia seeds, accounting for more than 90% of the total seed quantity, smoothly pass through the first circular holes and fall into the corresponding hopper 5 below. Simultaneously, medium-sized shells (thickness <24mm) are flat and longer than 24mm, so they can only pass vertically through the first circular hole. Only a small number of medium-sized shells will pass through the hole and enter the hopper 5 along with the camellia seeds. Large camellia seeds (diameter >24mm) and large shells are retained and continue to move towards the third sorting ring 34, achieving the initial separation of small and medium-sized seeds from large seeds and large shells.

[0029] The material intercepted by the second sorting ring 33 enters the area of ​​the third sorting ring 34. The third sorting ring 34 has second strip-shaped holes with a width of 12-12.5mm at equal intervals. This size is for medium-sized fruit shells that are less than 12mm thick and flat. Under the rotation of the sorting structure 3, the medium-sized fruit shells fall into the corresponding hopper 5 below through the second strip-shaped holes; while large-sized camellia seeds with a diameter of 25-30mm and large-sized fruit shells with a width of ≥15mm cannot pass through because their size is larger than the width of the strip-shaped holes. They are intercepted and move towards the fourth sorting ring 35, effectively removing medium-sized fruit shells from the material and improving the purity of large seeds in the remaining material.

[0030] The material after the third-stage screening enters the fourth sorting ring 35 area. The fourth sorting ring 35 has evenly spaced second circular holes with a diameter of 30mm, a size precisely matched to the maximum diameter of large-sized camellia seeds (approximately 30mm). Under the action of centrifugal force and gravity, the remaining approximately 10% of the large-sized camellia seeds smoothly pass through the second circular holes and fall into the corresponding hopper 5 below; while large-sized shells with a thickness greater than 30mm or irregular shapes are trapped because they cannot pass through the circular holes and are eventually discharged along the channel to the discharge end on the driven ring 36 side, completing the separation of large seeds from the remaining large shells.

[0031] During the grading and sorting process, the four hoppers 5, which correspond to the sorting rings at each level, collect materials simultaneously. Operators can flexibly control the discharge rate by using manual or electric valves at the bottom discharge port according to the amount of material collected in each hopper 5, and transfer the sorted materials to the next processing stage to achieve efficient utilization of the sorted materials.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
