Description
Technical Field
[0001] This utility model relates to the field of camellia seeds, and in particular to a camellia seed stratification screening mechanism with an automatic impurity removal device. Background Technology
[0002] Camellia oleifera seeds, commonly known as tea seeds, are the seeds of the Camellia oleifera tree, a plant in the Theaceae family. The Camellia oleifera tree is one of the main woody oil-bearing tree species in my country, with a cultivation history of more than 2,000 years. Camellia oleifera seeds are spherical, flattened round, or olive-shaped, with a diameter of about 1-2.5 cm. The outer skin of the seed is hard, dark brown or brown, with a smooth surface or fine texture. After peeling off the outer skin, the inside is a white or light yellow kernel, which is rich in oil.
[0003] Camellia seeds are an important raw material for producing high-quality edible oil. Before pressing, they need to be screened and impurities removed. On the one hand, harvested camellia seeds are often mixed with impurities such as leaves, branches, soil, and fruit shells. If these impurities are not removed, they will affect the service life of subsequent processing equipment and reduce the quality of camellia oil. Traditional screens are prone to clogging, affecting the impurity removal effect and efficiency, and require frequent cleaning and maintenance. Moreover, the screening machine must be turned off during maintenance, which reduces the screening efficiency of camellia seeds. Therefore, a layered screening mechanism for camellia seeds with an automatic impurity removal device is proposed to solve the above problems. Utility Model Content

The right end of the rotating rod 3 passes through to the right side of the screening box 1 and is rotatably mounted with the screening box 1. A rotating assembly 4 for rotating the rotating rod 3 is provided on the right side of the screening box 1. A pushing assembly 5 for pushing out impurities is provided inside the screening screen 2. First, camellia seeds can be poured onto the top screening screen 2. When it is necessary to screen the camellia seeds on the screening screen 2, the rotating assembly 4 can drive the rotating rod 3 to rotate, and the rotating rod 3 can drive the screening screen 2 to rotate, thereby screening the camellia seeds on the screening screen 2. After the camellia seeds are screened, the impurities on the screening screen 2 can be pushed out by the pushing assembly 5 for convenience when screening camellia seeds again.
[0032] Reference Figure 1-6 The rotating assembly 4 includes two sets of gears 41, which are fixedly mounted on the surface of the rotating rod 3. A toothed plate 42 is provided on the right side of the screening box 1, meshing with the gears 41. An electric push rod 43 is fixedly mounted on the right side of the screening box 1, with its telescopic end fixedly mounted to the front side of the toothed plate 42. Through the mutual cooperation of the gears 41, toothed plate 42, and electric push rod 43, when it is necessary to screen the camellia seeds on the screening screen 2, the electric push rod 43 can be activated. The telescopic end of the electric push rod 43 drives the toothed plate 42 to move to the rear side. 42 moves to the back, driving two sets of gears 41, rotating rod 3 and screening screen 2 to rotate, thereby screening the camellia seeds on the screening screen 2. A protective cover 44 is provided on the right side of the screening box 1. The left side of the protective cover 44 contacts the right side of the screening box 1. The electric push rod 43 is located inside the protective cover 44. The protective cover 44 is detachably installed and removed from the screening box 1 by bolts. The protective cover 44 can protect the toothed plate 42 and prevent camellia seeds from entering the toothed plate 42, thereby affecting the transmission of the toothed plate 42 and gear 41.
[0033] Reference Figure 1-6The driving component 5 includes two sets of fixed boxes 51, which are fixedly installed inside the screening screen 2. A motor 52 is fixedly installed on the front side of the inner wall of the fixed box 51. A bidirectional screw 53 is fixedly installed at the output end of the motor 52.

A glass 10 is provided on the left side of the screening box 1. The four corners of the left side of the glass 10 are detachably installed with the screening box 1 by bolts. Through the cooperation of the observation port 9 and the glass 10, the amount of camellia seeds loaded in the collection bin 6 can be observed, thereby preventing too many camellia seeds in the collection bin 6, which would cause the camellia seeds to spill into the screening box 1.
[0034] Working principle: First, the camellia seeds can be poured onto the top sieve 2. When it is necessary to sieve the camellia seeds on the sieve 2, the electric push rod 43 can be activated. The telescopic end of the electric push rod 43 drives the toothed plate 42 to move to the back side. The movement of the toothed plate 42 to the back side drives the two sets of gears 41, the rotating rod 3, and the sieve 2 to rotate, thereby sieving the camellia seeds on the sieve 2. The sieved camellia seeds will enter the collection bin 6. When the collection bin 6 is full of camellia seeds, the solid... Remove the bolts that limit the collection bin 6 and the screening box 1, then pull out the collection bin 6. Finally, the screened camellia seeds can be bagged. After the camellia seeds are screened, the motor 52 can be started. The output end of the motor 52 drives the bidirectional screw 53 to rotate. The rotation of the bidirectional screw 53 drives the screw block 54 and the cleaning brush 55 to move. The movement of the cleaning brush 55 can clean the impurities on the screening screen 2. The impurities will enter the guide block 7. Since the guide block 7 is inclined, the impurities on the guide block 7 will be discharged through the discharge port 8.
