[0040] Please see attached Figures 1 to 5In one embodiment of the present invention, a tea oil fruit shelling mechanism includes a frame 10, a driving mechanism 20, a feeding section 30, a pre-extrusion section 40 and a shelling section 50 arranged in sequence from top to bottom, wherein the feeding section 30 is provided with a feeding port 310,

[0041] The pre-extrusion section 40 includes a first fixed outer cylinder 410 and a first rotating inner cylinder 430 which are coaxially arranged. The first fixed outer cylinder 410 is fixedly connected to the frame 10. The inner wall of the first fixed outer cylinder 410 has a taper which gradually shrinks from top to bottom. The first fixed outer cylinder 410 is a flexible material structure, and the first rotating inner cylinder 430 is a rigid material structure. The first rotating inner cylinder 430 is connected to the driving mechanism 20 and moves synchronously with the driving mechanism 20. A pre-extrusion gap 440 matching the oil tea fruit 60 is provided between the first fixed outer cylinder 410 and the first rotating inner cylinder 430, and the pre-extrusion gap 440 is connected to the feeding section 30.

[0042] The shelling section 50 includes a second fixed outer cylinder 510 and a second rotating inner cylinder 530 which are coaxially arranged. The second fixed outer cylinder 510 is connected to the frame 10. The inner wall of the second fixed outer cylinder 510 has a taper which gradually shrinks from top to bottom. The second fixed outer cylinder 510 and the second rotating inner cylinder 530 are both rigid material structures. The second rotating inner cylinder 530 is connected to the driving mechanism 20 and moves synchronously with the driving mechanism 20. There is an extrusion shelling gap 540 matching the oil tea fruit 60 between the second fixed outer cylinder 510 and the second rotating inner cylinder 530, and the extrusion shelling gap 540 is connected to the pre-extrusion gap 440.

[0043] The tea fruit 60 dropped from the pre-extrusion gap 440 enters the extrusion and shelling gap 540 for shelling, and the shelled tea shells and tea seeds 61 fall out from the lower end of the extrusion and shelling gap 540 .

[0044] Specifically, the tea fruit 60 enters the pre-extrusion section 40 through the feed port 310 of the feed section 30. The first fixed outer cylinder 410 has a taper that gradually shrinks from top to bottom and adopts a flexible material structure, preferably a polyurethane wear-resistant material with a hardness of HRC equal to 18 to 20. The tea fruit 60 is subjected to force buffering protection during the kneading and shelling process, which reduces the damage to the tea seeds 61. The first rotating inner cylinder 430 adopts a rigid material structure, such as an iron structure. The first rotating inner cylinder 430 is connected to the driving mechanism 20 and moves synchronously. The tea fruit 60 is initially squeezed 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 kneading and squeezing of the tea fruit 60 is a pre-stress effect for shelling the tea fruit 60, which causes initial and superficial damage to the epidermis of the tea fruit 60.

[0045] The pre-extruded tea fruit 60 continues to move downward into the shelling section 50, which includes a second fixed outer cylinder 510 and a second rotating inner cylinder 530, both of which are rigid material structures, such as iron structures. 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 tea fruit 60 is further squeezed 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 tea fruit 60 is forcibly peeled off, so that the tea seeds 61 are separated from the shell. The shelled tea shells and tea seeds 61 fall out from the lower end of the extrusion and shelling gap 540 after shelling, completing the entire shelling process.

[0046] In the present application, the shell of the tea fruit 60 can be quickly and effectively broken through the continuous extrusion of the pre-extrusion section 40 and the shelling section 50, and the separation efficiency of the tea seeds 61 from the shell is high, which reduces the labor intensity; by setting the pre-extrusion section 40 and the shelling section 50, the tea fruit 60 is shelled in stages, and the tea fruit 60 after being squeezed and kneaded by the pre-extrusion section 40, after entering the shelling section 50, because the second fixed outer cylinder 510 and the second rotating inner cylinder 530 are both rigid material structures, the force and shelling strength are significantly greater than those of the pre-extrusion section 40, thereby resulting in the complete separation of the shell and seeds of the tea fruit 60. Since the tea fruit 60 has been pre-treated in the pre-extrusion section 40, the damage to the tea seeds 61 can be greatly reduced during the shelling process in the shelling section 50. To a certain extent, the damage to the tea seeds 61 can be reduced, and the breaking rate can be increased, thereby effectively improving the quality of the tea seeds 61. The tea fruit 60 is buffered and protected during the rubbing and shelling process, thereby reducing the damage to the tea seeds 61.

[0048] Specifically, the speed reduction mechanism 220 receives power from the driving motor 210 and performs speed reduction. The speed reduction mechanism 220 can adopt a conventional structure. The input end of the speed reduction mechanism 220 is connected to the output end of the driving motor 210. The output end of the speed reduction mechanism 220 is connected to the rotating main shaft 240 through the coupling 230. The coupling 230 connects the output end of the speed reduction mechanism 220 with the rotating main shaft 240 to ensure that the two can rotate synchronously and smoothly, and can also compensate for the change in the relative position of the two shafts caused by manufacturing, installation errors or deformation during operation to a certain extent, so as to ensure the stability of the transmission. The rotating main shaft 240 extends vertically and is rotatably connected to the frame 10, and drives the first rotating inner cylinder 430 and the second rotating inner cylinder 530 to rotate synchronously.

[0049] As a preferred embodiment, the frame 10 includes a first bracket plate 110, a second bracket plate 120, a third bracket plate 130, a fourth bracket plate 140, a fifth bracket plate 150 and a vertical fixing screw rod 160 which are arranged in parallel and spaced order from top to bottom, wherein:

[0055] Among them, the vertical fixed screw rod 160 is arranged to vertically penetrate the first through hole, the second through hole, the third through hole, the fourth through hole and the fifth through hole, and the upper end of the vertical fixed screw rod 160 is connected to the first bracket plate 110 through the first nut 170, and the lower end of the vertical fixed screw rod 160 is connected to the third bracket plate 130 through the second nut 180; the deceleration mechanism 220 is connected to the first bracket plate 110, the feeding section 30 is connected between the first bracket plate 110 and the second bracket plate 120, the first fixed outer cylinder 410 is connected between the second bracket plate 120 and the third bracket plate 130, and the second fixed outer cylinder 510 is connected between the third bracket plate 130 and the fourth bracket plate 140.

[0056] Specifically, the frame 10 is composed of a first bracket plate 110, a second bracket plate 120, a third bracket plate 130, a fourth bracket plate 140, a fifth bracket plate 150 and a vertical fixing screw rod 160 which are arranged in parallel and spaced from top to bottom to form a stable supporting structure; the vertical fixing screw rod 160 runs through the first bracket plate 110 to the fifth bracket plate 150, and is fixed at the upper and lower ends by a first nut 170 and a second nut 180, respectively, to ensure the relative position stability between the bracket plates;

[0057] In this embodiment, through the cooperation of the multi-layer support plates and the vertical fixed screw rod 160, the frame 10 has extremely high stability and rigidity, and can withstand the large forces and vibrations generated during the shelling process; the through holes and through holes opened on each support plate provide an accurate positioning reference for the assembly of each component, ensuring the assembly accuracy and operation stability of the entire mechanism.

[0058] As a preferred embodiment, the inner wall of the first fixed outer cylinder 410 is a solid wall surface, and the first rotating inner cylinder 430 includes an upper mounting plate 431 and a lower mounting plate 432 which are arranged in parallel and spaced apart, and a plurality of squeezing rollers 433 which are evenly spaced apart around the rotating main shaft 240, wherein a sixth through hole (not shown) for the rotating main shaft 240 to pass through is provided in the middle of the upper mounting plate 431 and the lower mounting plate 432, and the top end of each squeezing roller 433 is connected to the upper mounting plate 431, and the lower end is connected to the lower mounting plate 432, and the spacing distance between two adjacent squeezing rollers 433 is smaller than the fruit diameter of the oil tea fruit 60.

[0059] Specifically, the inner wall of the first fixed outer cylinder 410 is a solid wall surface, and the first rotating inner cylinder 430 includes an upper mounting plate 431, a lower mounting plate 432 and a plurality of squeezing rollers 433. The upper mounting plate 431 and the lower mounting plate 432 are arranged in parallel and spaced apart, and are connected to the rotating main shaft 240 through the sixth through hole, so as to ensure that the first rotating inner cylinder 430 can move synchronously with the rotating main shaft 240. Preferably, the top end of each squeezing roller 433 is rotatably connected to the upper mounting plate 431, and the lower end is rotatably connected to the lower mounting plate 432.

[0060] A plurality of squeezing rollers 433 are evenly spaced around the rotating main shaft 240 to form a roller-like structure. During rotation, these squeezing rollers 433 will generate continuous and even squeezing force on the tea fruit 60. The interval between two adjacent squeezing rollers 433 is smaller than the diameter of the tea fruit 60. When the tea fruit 60 is in the pre-squeezing gap 440 formed between the solid wall and the squeezing rollers 433, it will be squeezed from multiple directions, which facilitates the initial and superficial destruction of the tea fruit 60.

[0061] Furthermore, the inner wall of the first fixed outer cylinder 410 is provided with a plurality of first spiral ribs 420 evenly spaced along the circumference of the first fixed outer cylinder 410 for helping the oil-tea fruit 60 to be squeezed and dropped downward.

[0062] In this embodiment, by providing the first spiral rib 420, the oil-tea fruit 60 can be continuously pushed by the first spiral rib 420 during the downward movement. The oil-tea fruit 60 has a certain function of squeezing and discharging downward, reducing the possibility of jamming and blocking. The first spiral rib 420 also increases the contact area and friction with the oil-tea fruit 60 to a certain extent, thereby improving the shelling effect.

[0063] As a preferred embodiment, the second fixed outer cylinder 510 includes a plurality of shelling rollers 520 evenly spaced around the rotating main shaft 240, the third bracket plate 130 is provided with first connecting holes 131 corresponding to the shelling rollers 520, the fourth bracket plate 140 is provided with second connecting holes 141 corresponding to the shelling rollers 520, the upper end of each shelling roller 520 is connected to the first connecting hole 131, and the lower end of each shelling roller 520 is connected to the second connecting hole 141.

[0064] Specifically, the plurality of shelling rollers 520 disposed in the second fixed outer cylinder 510 are evenly spaced around the rotating main shaft 240, so that the oil-tea fruit 60 can be subjected to all-round shelling when passing through, thereby improving the uniformity and efficiency of shelling. Preferably, the upper end of each of the shelling rollers 520 is rotatably connected to the first connecting hole 131, and the lower end of each of the shelling rollers 520 is rotatably connected to the second connecting hole 141. The contact between the shelling rollers 520 and the oil-tea fruit 60 is the main wear point during the shelling process. By reasonably designing the material, hardness and surface structure of the shelling rollers 520, and optimizing the contact mode between the shelling rollers 520 and the oil-tea fruit 60, wear can be effectively reduced and the service life of the equipment can be extended.

[0065] As a preferred embodiment, the second rotating inner cylinder 530 includes a solid cylinder wall 531 and a lower end plate 532, the upper end of the solid cylinder wall 531 is connected to the lower mounting plate 432, the lower end of the solid cylinder wall 531 is connected to the lower end plate 532, and the lower end plate 532 is provided with a seventh through hole (not shown) for the rotating main shaft 240 to pass through.

[0066] Furthermore, a plurality of second spiral ribs 550 are arranged on the outer wall of the solid cylinder wall 531 at even intervals along the circumference of the solid cylinder wall 531 to help push the oil-tea fruit 60 to be squeezed and fall downward.

[0067] In this embodiment, by providing the second spiral rib 550, the oil-tea fruit 60 can be continuously pushed by the second spiral rib 550 during the downward movement. The oil-tea fruit 60 has a certain function of squeezing and discharging downward, reducing the possibility of jamming and blocking. The second spiral rib 550 also increases the contact area and friction with the oil-tea fruit 60 to a certain extent, thereby improving the shelling effect.

[0068] Furthermore, the upper end of the rotating main shaft 240 is rotatably connected to the first bracket plate 110 via the first bearing seat 250, and the lower end of the rotating main shaft 240 is rotatably connected to the fifth bracket plate 150 via the second bearing seat 260. Since the second bearing seat 260 is located in the discharge area, preferably, the second bearing seat 260 is a dustproof bearing seat, thereby improving the stability and life of the entire device.

[0069] As a preferred example, the upper mounting plate 431, the lower mounting plate 432 and the lower end plate 532 are arranged with the same diameter.

[0070] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
