Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing machinery, specifically a pretreatment device for camellia seeds. Background Technology

[0002] Camellia seeds are rich in nutrients such as crude fat and are an important raw material for producing high-quality camellia seed oil. Camellia seed oil is highly stable and resistant to storage, making it popular in the edible oil market. Camellia seed pretreatment is a key preliminary step in the production of camellia seed oil. It requires the sequential completion of processes such as seed selection, cleaning and grading, and shelling and separation. The separation effect is achieved through screen vibration to ensure the quality and purity of camellia seed oil.

[0003] In the current pretreatment process, the fruit and shell of camellia seeds are separated by a shelling drum, and then sieving is achieved by a vibrating screen. However, in actual use, filtering out the fine residue present during the harvesting of camellia seeds with a screen causes it to adhere to the surface of the seeds and disperse into the air, reducing the overall quality of the product and causing dust pollution. Camellia seed dust is flammable dust, and when it reaches a certain concentration, it can cause a dust explosion when exposed to static electricity or an open flame, resulting in personal injury and property damage. In view of this, the inventor urgently needs to design a device that can effectively absorb airborne dust to reduce the occurrence of accidents and ensure product quality and production efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a pretreatment device for camellia seeds to solve the technical problem of serious dust pollution during the shelling process of camellia seeds.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pretreatment device for camellia seeds, including a shelling machine, on which a vacuum cleaner is installed. The vacuum cleaner is connected to a negative pressure fan via a suction pipe. The negative pressure fan generates a negative pressure airflow, which draws the dust and debris generated during the shelling process of the camellia seeds into the suction pipe for centralized collection and treatment. A water pump is installed on one side of the shelling machine, and the water outlet of the water pump is connected to a water spray pipe. The nozzle of the water spray pipe sprays atomized water droplets towards the receiving plate area below it, adsorbing the escaped dust and causing it to fall onto the surface of the receiving plate, thus forming a dust removal system.

[0006] By adopting the above technical solutions, the shelling machine, along with the vacuum cleaner and negative pressure fan, can actively collect the dust and debris generated during the shelling process, significantly improving the working environment and effectively preventing dust from spreading in the working area.

[0007] Furthermore, the receiving plate has grooves at both ends, and a scraper is installed in the groove. The scraper has a round handle to drive the scraper to slide. The bottom of the scraper has a rubber sealing strip to ensure tight contact with the surface of the receiving plate.

[0008] By adopting the above technical solution, the combined use of the chute and scraper makes the cleaning of the receiving plate surface simple and efficient. Operators can easily complete the cleaning using the round handle. The design of the chute ensures that the scraper can move smoothly along the predetermined trajectory, avoiding deviation or jamming.

[0009] Furthermore, the top of the shelling machine is equipped with a discharge port, which has a funnel-shaped expansion structure and an anti-stick coating on its inner wall for discharging camellia fruits.

[0010] By adopting the above technical solution, the funnel-shaped discharge port expands the feeding area, making the feeding of camellia fruit smoother and more convenient. Its gradually narrowing structure is conducive to the concentrated falling of materials and avoids the accumulation of materials.

[0011] Furthermore, a shelling roller is provided at the bottom of the feeding port. The shelling roller is electrically connected to a motor, and the motor speed is adjustable to meet the shelling needs of camellia fruits at different stages of maturity.

[0012] By adopting the above technical solution, the adjustable speed motor and the shelling drum can adjust the shelling force according to the ripeness of the camellia fruit, ensuring the shelling effect while avoiding damage to the seeds. By adjusting the motor speed, the working intensity of the shelling drum can be precisely controlled to adapt to the processing needs of camellia fruits of different hardness and size.

[0013] Furthermore, the vacuum cleaner is provided with a discharge port at the location opposite the negative pressure position. The discharge port has a funnel-shaped expansion structure to guide the flow of materials.

[0014] By adopting the above technical solution, the funnel-shaped discharge port optimizes the material flow path. Its funnel-shaped expansion structure effectively reduces the material flow resistance, allowing the separated camellia seeds to be output smoothly, avoiding the accumulation and blockage of materials at the outlet, and ensuring the stability of continuous production.

[0015] Furthermore, the motor output end is connected to the cam via a pulley, and the cam has a ring on its outside, which is driven to rotate by the motor.

[0016] By adopting the above technical solutions, belt drives have buffering and shock absorption functions, effectively absorbing vibrations during motor operation, ensuring reliable equipment operation, improving overload protection capabilities, and extending equipment service life.

[0017] Furthermore, the cam is connected to the screen via a connecting rod, driving the screen to vibrate at high frequency along the moving groove.

[0018] By adopting the above technical solution, the cam drives the screen to generate high-frequency vibration through the connecting rod. This mechanical transmission method can produce a stable and reliable vibration effect, realize efficient material separation, and the vibration frequency and amplitude can be precisely controlled by adjusting the cam shape and speed to meet the screening needs of different materials.

[0019] Furthermore, the screen has two layers, with the upper screen having a larger aperture than the lower screen, enabling the camellia seeds to be separated from their outer shells in stages.

[0020] By adopting the above technical solution, the double-layer screen achieves the step-by-step separation of camellia seeds from their outer shells. The upper screen performs preliminary coarse screening to separate large pieces of the outer shell, while the lower screen performs fine screening to ensure the purity of the final product, effectively improve the separation accuracy, and avoid omissions or mixing caused by single screening.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model, through the design of a negative pressure fan and a water pump, firstly, through the synergistic action of the shelling machine, the vacuum cleaner, and the negative pressure fan, can efficiently collect the dust and debris generated during the shelling process, significantly reducing pollution in the production environment. At the same time, the atomizing dust removal system composed of the water pump and the water spray pipe further adsorbs the escaped dust, forming a dual dust removal mechanism, which greatly improves the cleaning effect. The motor-driven shelling roller adopts an adjustable speed design, which can adapt to the shelling needs of camellia fruits of different ripeness, ensuring stable and reliable shelling quality.

[0023] 2. This utility model utilizes a cam design, which drives a double-layer screen to vibrate at high frequency, achieving a step-by-step fine separation of camellia seeds from their outer shells, thus improving screening accuracy and production efficiency. The receiving plate is equipped with a sliding scraper, which facilitates quick cleaning of sediments and reduces manual maintenance workload. The anti-stick coating on the discharge port and the trumpet-shaped structure of the outlet effectively optimize the material flow path, prevent blockages, and improve the overall smoothness of operation, thereby enhancing the practicality and economy of the device.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] In this implementation:

[0031] A pretreatment device for camellia seeds, such as Figure 1-4 As shown, the system includes a shelling machine 16, on which a vacuum cleaner 3 is installed. The vacuum cleaner 3 is connected to a negative pressure fan 5 via a suction pipe 4. The negative pressure fan 5 generates a negative pressure airflow, which sucks the dust and debris generated during the shelling process of camellia seeds into the suction pipe 4. The dust and debris are then collected and processed by the negative pressure fan 5. A water pump 1 is installed on one side of the shelling machine 16. The water outlet of the water pump 1 is connected to a water spray pipe 2. The nozzle of the water spray pipe 2 sprays atomized water droplets towards the receiving plate 12 area below it, adsorbing the escaped dust and causing it to fall onto the surface of the receiving plate 12, forming a dust removal system. The coordinated work of the shelling machine 16, the vacuum cleaner 3, and the negative pressure fan 5 can actively collect the dust and debris generated during the shelling process, significantly improving the working environment and effectively preventing the spread of dust in the working area. The dual dust removal mechanism ensures the cleanliness of the production environment and avoids the impact of dust spread on the health of operators.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The receiving plate 12 has grooves 14 at both ends, and a scraper 15 is installed in the grooves 14. The scraper 15 is equipped with a round handle to drive the scraper 15 to slide. The bottom of the scraper 15 is equipped with a rubber sealing strip to ensure tight contact with the surface of the receiving plate 12. The combined use of the grooves 14 and the scraper 15 makes the cleaning of the surface of the receiving plate 12 simple and efficient. The operator can easily complete the cleaning by using the round handle. The design of the grooves 14 ensures that the scraper 15 can move smoothly along the predetermined trajectory, avoiding deviation or jamming. This reduces the labor intensity of manual cleaning, improves the continuous operation capability of the equipment, extends the service life of the scraper, and reduces maintenance costs.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4The top of the shelling machine 16 is equipped with a discharge port 7, which has a funnel-shaped expansion structure and an anti-stick coating on its inner wall. It is used to feed camellia fruits. The funnel-shaped discharge port 7 expands the feeding area, making the feeding of camellia fruits smoother and more convenient. Its gradually narrowing structure is conducive to the concentrated falling of materials, avoiding material accumulation, improving production efficiency, avoiding equipment failure caused by material blockage, reducing material residue, improving raw material utilization, and reducing production costs.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The bottom of the feeding port 7 is equipped with a shelling roller 8, which is electrically connected to a motor 6. The speed of the motor 6 is adjustable to adapt to the shelling needs of camellia fruits at different stages of maturity. The cooperation between the adjustable speed motor 6 and the shelling roller 8 can adjust the shelling force according to the maturity of the camellia fruits, ensuring the shelling effect while avoiding damage to the seeds. By adjusting the motor speed, the working intensity of the shelling roller 8 can be precisely controlled to adapt to the processing needs of camellia fruits of different hardness and size, improving the versatility of the equipment, effectively reducing energy consumption, and achieving energy-saving goals while ensuring production efficiency.

[0035] See Figure 1 , Figure 2 , Figure 4 The vacuum cleaner 3 has a discharge port 13 located opposite the negative pressure position. The discharge port 13 has a funnel-shaped expansion structure to guide the material flow. The funnel-shaped discharge port 13 optimizes the material flow path and its funnel-shaped expansion structure effectively reduces the material flow resistance, allowing the separated camellia seeds to be output smoothly. This avoids the accumulation and blockage of materials at the outlet, ensures the stability of continuous production, reduces splashing and scattering of materials during the output process, and improves the raw material recovery rate.

[0036] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The output end of motor 6 is connected to cam 9 via a pulley. Cam 9 has a ring on its outside, which is driven to rotate by motor 6. Belt drive has buffering and shock absorption functions, which can effectively absorb the vibration when the motor is running, ensure reliable operation of equipment, improve overload protection capability, extend equipment service life, and reduce equipment failure rate. Belt drive also has the advantages of convenient installation and low cost, which reduces manufacturing cost while ensuring performance.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4Cam 9 is connected to screen 10 via a connecting rod, driving screen 10 to vibrate at high frequency along moving groove 11. Cam 9 drives screen 10 to generate high-frequency vibration via connecting rod. This mechanical transmission method can produce a stable and reliable vibration effect, realize efficient material separation. The vibration frequency and amplitude can be precisely controlled by adjusting the cam shape and speed to meet the screening needs of different materials, effectively prevent screen blockage, and improve screening accuracy.

[0038] See Figure 1 , Figure 2 , Figure 3 The screen 10 has two layers. The upper screen has a larger aperture than the lower screen, which enables the step-by-step separation of camellia seeds from their outer shells. The double-layer screen 10 achieves step-by-step separation of camellia seeds from their outer shells. The upper screen performs preliminary coarse screening to separate large pieces of the outer shell, while the lower screen performs fine screening to ensure the purity of the final product. This effectively improves the separation accuracy, avoids omissions or mixing caused by single screening, optimizes the separation effect, improves the overall processing efficiency, reduces the workload of manual re-inspection, and improves the quality of the finished product.

[0039] The implementation principle of this embodiment is as follows: Camellia fruits are fed into the funnel-shaped discharge port 7 with an anti-stick coating, and the shelling roller 8 driven by the motor 6 performs shelling. The funnel-shaped structure of the discharge port 13 guides the material output. During the output process, the negative pressure fan 5 sucks up dust through the dust collector 3 and the dust collection pipe 4. At the same time, the water pump 1 sprays atomized water droplets onto the receiving plate 12 through the water spray pipe 2 to absorb the escaped dust. The output end of the motor 6 drives the cam 9 to rotate through the pulley, and the double-layer screen 10 vibrates at high frequency along the moving groove 11 through the connecting rod. The upper large-diameter screen separates the outer shell, and the lower screen finely screens the camellia seeds. The scraper 15 cleans the deposits on the surface of the receiving plate 12 through the sliding groove 14, realizing continuous operation of shelling, dust removal and grading.
