[0040] Please refer to the attached Figures 1 to 5 The utility model provides a kind of tea oil fruit shelling mechanism in one embodiment, including rack 10, drive mechanism 20, from top to bottom sequentially arranged feed section 30, pre-extrusion section 40 and shelling section 50, wherein, the feed section 30 is equipped with feed port 310,

[0041] The pre-extrusion section 40 includes coaxially arranged first fixed outer cylinder 410 and first rotating inner cylinder 430, the first fixed outer cylinder 410 is fixedly connected with the rack 10, the inner wall of the first fixed outer cylinder 410 has taper that gradually shrinks from top to bottom, the first fixed outer cylinder 410 is of flexible material structure, the first rotating inner cylinder 430 is of rigid material structure, the first rotating inner cylinder 430 is connected with the drive mechanism 20 and moves synchronously with the drive mechanism 20, the first fixed outer cylinder 410 and the first rotating inner cylinder 430 have pre-extrusion gap 440 matched with camellia fruit 60, and the pre-extrusion gap 440 is communicated with the feed section 30.

[0042] The shelling section 50 includes coaxially arranged second fixed outer cylinder 510 and second rotating inner cylinder 530, the second fixed outer cylinder 510 is connected with the rack 10, the inner wall of the second fixed outer cylinder 510 has taper that gradually shrinks from top to bottom, the second fixed outer cylinder 510 and the second rotating inner cylinder 530 are both of rigid material structure, the second rotating inner cylinder 530 is connected with the drive mechanism 20 and moves synchronously with the drive mechanism 20, the second fixed outer cylinder 510 and the second rotating inner cylinder 530 have extrusion shelling gap 540 matched with camellia fruit 60, and the extrusion shelling gap 540 is communicated with the pre-extrusion gap 440.

[0043] Wherein, camellia fruit 60 falling from the pre-extrusion gap 440 enters extrusion shelling gap 540 to shell, and camellia shell and camellia seed 61 after shelling are all dropped from the lower end of the extrusion shelling gap 540.

[0044] Specifically, the oil tea fruit 60 enters the pre-extrusion section 40 through the feed inlet 310 of the feed section 30. The first fixed outer cylinder 410 has a taper that gradually shrinks from top to bottom, and is made of a flexible material structure, preferably a polyurethane wear-resistant material with a hardness of HRC equal to 18-20. The oil tea fruit 60 is protected by buffering force during the rubbing and shelling process, reducing damage to the oil tea seeds 61. The first rotating inner cylinder 430 is made of a rigid material structure, such as iron structure. The first rotating inner cylinder 430 is connected with the driving mechanism 20 and moves synchronously. The oil tea fruit 60 is subjected to preliminary extrusion in the pre-extrusion gap 440 formed between the first fixed outer cylinder 410 and the first rotating inner cylinder 430 as the first rotating inner cylinder 430 rotates. The oil tea fruit 60 is rubbed and extruded, which is a pre-force for shelling of the oil tea fruit 60, and the outer skin of the oil tea fruit 60 is initially and superficially damaged.

[0045] The pre-extruded oil tea fruit 60 continues to enter the shelling section 50 downward. The shelling section 50 includes a second fixed outer cylinder 510 and a second rotating inner cylinder 530, both of which are made of a rigid material structure, such as iron structure. The second fixed outer cylinder 510 also has a taper that gradually shrinks from top to bottom. As the second rotating inner cylinder 530 rotates, the oil tea fruit 60 is subjected to further extrusion in the extrusion and shelling gap 540 formed between the second fixed outer cylinder 510 and the second rotating inner cylinder 530. The extrusion is more intense, and the outer skin of the oil tea fruit 60 is forcibly peeled off, so that the oil tea seeds 61 are separated from the shell. The shelled oil tea shell and oil tea seeds 61 fall out of the lower end of the extrusion and shelling gap 540, completing the entire shelling process.

[0046] In the present application, through the continuous extrusion of the pre-extrusion section 40 and the shelling section 50, the shell of the oil tea fruit 60 can be quickly and effectively broken, and the separation efficiency of the oil tea seeds 61 from the shell is high, reducing the labor intensity. By providing the pre-extrusion section 40 and the shelling section 50, the oil tea fruit 60 is shelled in stages. After the oil tea fruit 60 is extruded and rubbed in the pre-extrusion section 40, it enters the shelling section 50. Since the second fixed outer cylinder 510 and the second rotating inner cylinder 530 are made of a rigid material structure, the stress and shelling strength are significantly greater than that of the pre-extrusion section 40, resulting in complete separation of the shell and seeds of the oil tea fruit 60. Since the oil tea fruit 60 has been pretreated in the pre-extrusion section 40, the damage to the oil tea seeds 61 during the shelling process in the shelling section 50 can be greatly reduced, to some extent, the damage to the oil tea seeds 61 can be reduced, and the breaking rate can be improved, effectively improving the quality of the oil tea seeds 61. The oil tea fruit 60 is protected by buffering force during the rubbing and shelling process, reducing damage to the oil tea seeds 61.
