Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of camellia seed screening equipment, specifically relating to a camellia seed screening device. Background Technology
[0002] Camellia seeds are the fruit and seeds of the camellia tree, and are the core raw material for producing camellia oil. They are rich in oil (typically 40%-60%) and contain various bioactive components, making them a highly nutritious and economically valuable oilseed resource.
[0003] Camellia seed screening equipment is a key piece of equipment in the camellia seed processing. It is mainly used to clean, grade, and remove impurities from harvested camellia seeds, preparing them for subsequent drying, dehulling, and pressing processes. Choosing appropriate screening equipment can effectively improve the purity, uniformity, and processing efficiency of camellia seeds, ultimately enhancing the quality and oil yield of camellia oil.
[0004] Camellia seeds, due to their naturally high oil content, are prone to sticking together during the screening process. This sticking is mainly caused by the oil on the surface of the seeds and is significantly affected by factors such as humidity and temperature. Existing camellia seed screening equipment has a fixed angle between the screen box and the frame. If the fixed angle is too small, it is impossible to increase the material flow rate and impact force by increasing the angle, resulting in material accumulation on the screen surface and easier clogging of the screen holes. When operators encounter poor screening results, they cannot quickly and easily adjust the angle to try to improve the situation. They can only passively accept the situation or make more complex adjustments (such as replacing the screen or changing the vibration parameters, which often have limited effect).

The screen box, spring, arc-shaped seat, and rotating seat are integrated into one unit. When the arc-shaped seat moves, it drives the screen box to rotate along the arc-shaped seat, thereby achieving the purpose of adjusting the screen box angle.

[0018] A camellia seed sieving device, such as Figure 1 and Figure 2 As shown, the machine includes a frame and a screen box 1 corresponding to the frame. A vibration motor 3 is fixedly connected to the bottom of the screen box 1. The screen box 1 is provided with a feeding port 2, and a screen mesh corresponding to the feeding port 2 is provided inside the screen box 1. The screen box 1 is provided with a discharge port that cooperates with the screen mesh. Camellia seeds are added into the screen box 1 through the feeding port 2. The vibration motor 3 is started, and the vibration motor 3 drives the screen box 1 and the screen mesh to vibrate. The screen mesh screens the camellia seeds, and the screened camellia seeds flow out through the discharge port.
[0019] Furthermore, such as Figure 1 and Figure 2 As shown, a rotating seat 5 is rotatably connected to the frame, and an arc-shaped seat 7 is also slidably connected to the frame along a fan shape. Both the arc-shaped seat 7 and the rotating seat 5 are provided with springs 6 that cooperate with the screen box 1. A drive unit is provided on the frame, and a crank 17 is connected to the output end of the drive unit. A connecting rod 10 is rotatably connected to the crank 17, and the other end of the connecting rod 10 is rotatably connected to the arc-shaped seat 7. The drive unit includes a transmission box 9 fixed to the frame, a worm gear 15 is rotatably connected to the transmission box 9, and a knob is fixedly connected to the worm gear 15. A worm wheel 16 meshes with the worm gear 15, and the worm wheel 16 is coaxially fixed to the crank 17.
[0020] When the angle of the screen box 1 needs to be adjusted, the worm gear 15 is rotated by the knob, and the worm gear 15 drives the crank 17 to rotate through the worm wheel 16; the crank 17 drives the arc seat 7 to move through the connecting rod 10. The screen box 1, spring 6, arc seat 7 and rotating seat 5 are integrated into one unit, so that when the arc seat 7 moves, the arc seat 7 drives the screen box 1 to rotate along the arc seat 7, thereby achieving the purpose of adjusting the angle of the screen box 1. This allows the angle of the screen box to be adjusted according to the screening situation, improving the adaptability of the application.
[0021] Furthermore, such as Figure 2 As shown, the frame includes a front support leg 4 and a rear support leg 8 corresponding to the front support leg 4. A rotating seat 5 is rotatably connected to the front support leg 4, and an arc-shaped seat 7 is slidably connected to the rear support leg 8. A guide cylinder 11 is fixedly connected to the rear support leg 8, and an arc-shaped rod 12 is fixedly connected to the arc-shaped seat 7 and slidably connected to the guide cylinder 11. Multiple fixing holes 13 are evenly distributed along the circumference of the arc-shaped rod 12, and fixing bolts 14 that cooperate with the fixing holes 13 are passed through the guide cylinder 11. When the arc-shaped seat 7 moves, the arc-shaped seat 7 drives the arc-shaped rod 12 to slide along the guide cylinder 11. The fixing bolts 14 cooperate with the fixing holes 13 to fix the arc-shaped rod 12 and the guide cylinder 11, thereby fixing the arc-shaped seat 7 and improving the stability of the arc-shaped seat 7.
