Description

Technical Field

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

[0002] A golden camellia sorting device is a specialized mechanical device used for grading and quality control of golden camellia raw materials. Its core function is to efficiently sort golden camellia flowers, leaves, or processed tea leaves using automated or semi-automated methods to meet the processing requirements of different applications. This device can quickly separate whole flowers from broken flowers based on their size and shape, significantly improving the uniformity and commercial value of the raw materials. In practical applications, the sorting device not only improves production efficiency and reduces the cost and error of manual sorting, but also provides consistent raw materials for subsequent deep processing through precise grading, ensuring the stability of product quality.

[0003] During the screening process of Camellia chrysantha, larger flowers are prone to getting stuck in smaller sieve holes. This problem mainly stems from the irregular shape of Camellia chrysantha flowers – when the flowers roll in the net, their petals may be deformed due to mechanical compression, and some petals may be pressed into sieve holes that are smaller than their natural diameter.

[0004] How to design a Camellia chrysantha screening device to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a golden camellia screening device, which aims to improve the problems mentioned in the background.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments 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, 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 scope of protection of this utility model.

[0018] Example, refer to Figures 1-4 A golden camellia sorting device includes multiple upright frames 1. A load-bearing frame 2 is fixedly connected to the top of each upright frame 1. A sorting box 3 is fixedly connected to the bottom of each load-bearing frame 2. A support base 4 is fixedly connected to the top of each load-bearing frame 2. A motor 5 is fixedly connected to the top of each support base 4. A sprocket is fixedly mounted on the output shaft of the motor 5. A support frame 6 is fixedly connected to the side wall of the support base 4. An auxiliary shaft 7 is rotatably connected to the top of each support frame 6. A first rotating rod 8 and a second rotating rod 80 are rotatably mounted on the auxiliary shaft 7. The cross-sections of both the first rotating rod 8 and the second rotating rod 80 are gear-shaped. The toothed edge of the rotating rod is set in an arc. Fixed seats 9 are fixedly connected to both sides of the load-bearing frame 2. The main shaft 10 is rotatably connected to the fixed seats 9. A sprocket is fixedly sleeved on the main shaft 10. The main shaft 10 and the output shaft of the motor 5 are connected by chain and sprocket transmission. The main shaft 10 is set at an angle relative to the horizontal plane. Three fixing rings 21 are sleeved on the outer wall of the main shaft 10. The fixing rings 21 are evenly distributed in the length direction of the main shaft 10. Multiple connecting rods 22 are fixedly connected to the fixing rings 21. The connecting rods 22 are evenly distributed in a circle. Roller rings 23 are fixedly connected to the ends of the connecting rods 22.

[0019] A plurality of first roller rods 24 are fixedly connected to one side wall of the roller ring 23 located in the middle position, and a plurality of second roller rods 25 are fixedly connected to the other side wall. A gear meshing structure is formed between the first rotating rod 8 and the second roller rods 25. The plurality of first roller rods 24 and second roller rods 25 are circumferentially distributed at equal intervals. The distance between two adjacent first roller rods 24 is smaller than the distance between two adjacent second roller rods 25. A flexible sleeve 26 is fixedly fitted on the outer side wall of the first roller rods 24 and the second roller rods 25. Flexible thin plates are provided on both sides of the flexible sleeve 26. A partition plate 31 is fixedly connected inside the sorting box 3. The partition plate 31 corresponds to the position of the roller ring 23 located in the middle position. A feed plate 32 is fixedly connected to one side wall of the sorting box 3, and a discharge plate 33 is fixedly connected to the other side wall.

[0020] It should be noted that the first rotating rod 8 and the second rotating rod 80 correspond to the two middle sections of the three roller rings 23, respectively. The cross-section of the first rotating rod 8 is gear-shaped, and the toothed edge of the first rotating rod 8 is located between two adjacent second roller rods 25, similar to gear meshing. Before one of the second roller rods 25 is separated from the gear edge of the first rotating rod 8, the gear edge of the other first rotating rod 8 contacts the other second roller rod 25, causing the first rotating rod 8 to rotate continuously. The second rotating rod 80 and the first roller rod 24 adopt the same configuration, and the gear edge spacing of the second rotating rod 80 is set according to the spacing between two adjacent first roller rods 24.

[0021] The gear edge of the rotating rod is rounded, which is less likely to damage the camellia when pushing and jamming it compared to the gear edge with an obtuse angle. By setting a flexible sleeve 26 and a flexible thin plate on it, the flexible sleeve 26 can be made of food-grade silicone material, which prevents rigid compression of the camellia and damage to its surface when it comes into contact with the flexible sleeve 26.

[0022] The working principle of this Camellia chrysantha screening device is as follows: The motor 5 is started, driving the main shaft 10 to rotate via a chain. The main shaft 10 drives multiple connecting rods 22 to rotate circumferentially via a fixed ring 21, and drives multiple first roller rods 24 and multiple second roller rods 25 to rotate circumferentially via multiple roller rings 23. Camellia chrysantha to be screened is fed into the feed plate 32. Defective Camellia chrysantha, being the smallest in size, first falls into the sorting box 3 through the gaps between the first roller rods 24. Larger Camellia chrysantha particles, due to the inclined setting of the main shaft 10, move towards the discharge plate 33 under the influence of gravity. Naturally, smaller Camellia chrysantha particles fall into the sorting box 3 through the gaps between the second roller rods 25. Naturally, larger Camellia chrysantha particles fall from the discharge plate 33, completing the screening process.

[0023] When the multiple first roller rods 24 and multiple second roller rods 25 are in circular motion, the second rotating rod 80 and the first rotating rod 8 are also driven to rotate through gear meshing. The gears on the second rotating rod 80 and the first rotating rod 8 rotate and are inserted into the gaps between the first roller rod 24 and the second roller rod 25 respectively, pushing out the Camellia japonica stuck in the gaps and preventing the Camellia japonica from being stuck and affecting the screening efficiency.

[0024] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the 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.
