[0002] As is well known, an oil-tea fruit consists of an outer hairy shell and oil-tea seeds, and the oil-tea seeds consist of tea seed shells and tea kernels. The tea seed shells contain very little oil content and mainly contain lignin, cellulose, tannin, etc. Processing the oil-tea fruit after removing its inner and outer shells can not only greatly improve the oil yield and quality, increase the protein content and feeding value of the cake and meal, improve the palatability of the cake and meal, but also improve the equipment utilization rate, reduce the power consumption and equipment wear, reduce the refining load of the oil, simplify the refining process, and is more conducive to the intensive processing of tea saponin products and the comprehensive utilization of oil-tea.

[0003] The fruit of the oil-tea includes an oil-tea shell and oil-tea seeds. During the oil-refining process of the oil-tea fruit, it is necessary to first remove the shell of the oil-tea fruit to obtain the oil-tea seeds, and then perform processes such as pressing on the oil-tea seeds to obtain tea oil. Due to the influence of factors such as region, climate conditions, and maturity degree on the oil-tea fruit, the fresh fruits vary greatly in size, and the pericarp and seed coat are of different thicknesses.

[0004] In the prior art, in the shelling of oil-tea fruits, most of the traditional methods are adopted, that is, exposing the oil-tea fruits to the sun to crack their hairy shells and then taking out the oil-tea seeds, or adopting the manual shelling method. However, through manual processing, a large amount of labor is required, which is time-consuming and laborious. Or some general shelling equipment is also adopted in the prior art, and this kind of equipment is difficult to adapt to oil-tea fruits with different fruit diameters and is also difficult to be applicable to the shelling of green fruits. For example, Chinese Patent No. 201310533259.8 discloses an oil-tea fruit green fruit shelling machine, which mainly performs cutting and shelling on the dried or baked oil-tea green fruits.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solution 1 results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] Please refer to the attached Figures 1-3 , a camellia fruit shelling machine in an embodiment provided by the present invention includes a first driving mechanism 10, an upper grinding disc mechanism 20, and a lower grinding disc mechanism 30 located below the upper grinding disc mechanism 20; wherein, the upper grinding disc mechanism 20 is movably arranged vertically, and a grinding space 340 for separating the fruit shells of the camellia fruit 80 is formed between the upper pressing disc 210 mechanism and the lower pressing disc 210 mechanism; wherein,

[0037] The upper grinding disc mechanism 20 includes a pressing disc 210 and a pressing disc shaft 230. The pressing disc shaft 230 is vertically fixed to the bottom of the pressing disc 210, and the pressing disc 210 is provided with a feed hole 220 communicating with the grinding space 340;

[0038] The lower grinding disc mechanism 30 includes a moving disc 310 and a transmission sleeve 330. The moving disc 310 is provided with a vertical through hole 320 for the pressing disc shaft 230 to pass through; the transmission sleeve 330 is rotatably sleeved on the outer surface of the pressing disc shaft 230, and the transmission sleeve 330 is fixed to the bottom of the moving disc 310; the first driving mechanism 10 drives the transmission sleeve 330 to rotate around the pressing disc shaft 230 to separate the fruit shells of the camellia fruit 80 located in the grinding space 340.

[0039] It should be noted to those skilled in the art that the existing tea-oil camellia fruits 80 are generally shelled manually or by setting up equipment. This method requires the tea-oil camellia fruits 80 to be dried before shelling. And this application provides a novel tea-oil camellia fruit 80 shelling machine. The tea-oil camellia fruits 80 enter the grinding space 340 through the feeding hole 220. In a preferred embodiment, a corresponding hopper can be arranged at the position of the feeding hole 220 to facilitate centralized entry into the grinding space 340. The first driving mechanism 10 drives the transmission sleeve 330 to rotate around the pressure plate shaft 230, thereby driving the moving plate 310 to rotate. Since the pressure plate 210 can move vertically but cannot rotate around its own central axis, the pressure plate 210 can adapt to tea-oil camellia fruits 80 with a certain range of fruit diameters by its own weight. The tea-oil camellia fruits 80 are subjected to the grinding action between the pressure plate 210 and the moving plate 310 in the grinding space 340, so as to realize fruit shell separation. Through this grinding method, the rapid shelling of the tea-oil camellia fruits 80 can be realized, and the process can be continuous. It can adapt to tea-oil camellia fruits 80 with different fruit diameters by the self-weight of the pressure plate 210, which can effectively save the input of manpower and material resources and has high production efficiency.

[0040] Among them, the first driving mechanism 10 can be a driving motor, or other forms of driving mechanisms, such as a gasoline engine, an oil extraction machine, etc., as long as it can drive the transmission sleeve 330 to rotate around the pressure plate shaft 230. Those skilled in the art can select according to needs. In addition, the transmission connection mode between the first driving mechanism 10 and the transmission sleeve 330 can be chain drive, belt drive or gear drive, etc. Those skilled in the art can select according to needs.

[0041] Preferably, the bottom surface of the pressure plate 210 and / or the top surface of the moving plate 310 are formed with striped abrasion marks 350. By forming the abrasion marks 350 on the bottom surface of the pressure plate 210 and / or the top surface of the moving plate 310, after the tea-oil camellia fruits 80 enter the grinding space 340, under the rotation of the moving plate 310, they are oppressed by the gravity of the pressure plate 210, so that the tea-oil camellia fruits 80 are broken, increasing the friction between the tea-oil camellia fruits 80 and the pressure plate 210 and / or the moving plate 310 and improving the breaking efficiency.

[0042] As a preferred embodiment, the transmission sleeve 330 includes a sleeve body 331 and a bearing 332. The inner ring of the bearing 332 is fixedly sleeved on the outer surface of the pressure plate shaft 230. The inner surface of the sleeve body 331 is fixedly sleeved on the outer surface of the outer ring of the bearing 332. The top of the sleeve body 331 is fixedly connected to the bottom of the moving plate 310. Specifically, the number of bearings 332 can be set as needed. In a preferred embodiment, the number of bearings 332 is two. The two bearings 332 are arranged at intervals along the axial direction of the pressure plate shaft 230. Through the arrangement of the bearings 332, under the action of the first driving mechanism 10, the sleeve body 331 can smoothly rotate around the pressure plate shaft 230, thereby improving the efficiency of shell separation.

[0043] As another preferred embodiment, it also includes a shell cutting mechanism (not shown in the figure), which includes a second driving mechanism 410, a push auger 420 and a cutting assembly 430; the push auger 420 has an auger feed port (not shown in the figure) and an auger discharge port (not shown in the figure); the push auger 420 is transmission-connected to the second driving mechanism 410; the cutting assembly 430 is used to cut the shell of the tea fruit 80 from the auger discharge port, and the cutting assembly 430 includes a slotting knife 431, a connecting rod 432 and an adjusting torsion spring 433; wherein,

[0044] The adjusting torsion spring 433 has a first adjusting arm 434 and a second adjusting arm 435, wherein the first adjusting arm 434 is fixedly connected to the outer surface of the pushing auger 420, and the second adjusting arm 435 is cantilevered from the first adjusting arm 434 toward the auger discharge port;

[0045] The connecting rod 432 includes a first end and a second end that are relatively arranged, the first end is fixed to the second adjusting arm 435 on the side close to the pushing auger 420; the second end extends from the first end toward the auger discharge port; the slotting knife 431 is rotatably arranged on the second end.

[0046] It should be noted that, in order to further improve the efficiency of husk separation and increase the yield rate, in this embodiment, a husk cutting mechanism is provided. Specifically, the oil-tea fruit 80 enters the pushing auger 420 through the auger feed inlet. The pushing auger 420 is a technical device well-known to those skilled in the art and will not be elaborated here. Driven by the second driving mechanism 410 (the second driving mechanism 410 can be driven by a motor, gasoline engine or diesel engine, etc.), the oil-tea fruit 80 is pushed from the auger feed inlet to the auger discharge outlet. Since the cutting assembly 430 is arranged near the auger discharge outlet, as the pushing auger 420 continuously pushes, the oil-tea fruit 80 pushed to the auger discharge outlet will contact the grooving knife 431 of the cutting assembly 430. Through the action of the grooving knife 431, a crack slot is cut in the husk of the oil-tea fruit 80, and then it enters the grinding space 340 through the feed hole 220 of the pressure plate 210. This embodiment can cut the husk of green fruits, thereby realizing the husking process of green fruits.

[0047] In addition, by setting the adjusting torsion spring 433, it can adapt to oil-tea fruits 80 with different fruit diameters, thus ensuring the effect of husk cutting. It can be understood that when oil-tea fruits 80 with different fruit diameters pass through the cutting assembly, under the action of the adjusting torsion spring 433, the cutting force can be maintained, and cutting grooves are left on the husk.

[0048] It is worth noting that after the oil-tea fruit 80 cut by the cutting assembly 430 enters the grinding space 340, under the rotation of the moving disk 310 and the self-weight of the pressure plate 210, it is easier to shell, thereby improving the efficiency of husk separation and increasing the yield rate. The embodiment of the present application can realize the pre-treatment of shelling green fruits, thus facilitating the subsequent shelling process of green fruits.

[0049] As a preferred embodiment, a lifting mechanism 50 is further included. The lifting mechanism 50 includes a raw material hopper 510, a conveying frame 520, and a conveyor belt 530. The conveyor belt 530 is inclinedly arranged on the conveying mechanism. The raw material outlet of the raw material hopper 510 is arranged towards the lower end of the conveyor belt 530, and the upper end of the conveyor belt 530 is correspondingly arranged with the auger feed inlet of the pushing auger 420. Through the conveying action of the lifting mechanism 50, the oil-tea fruit raw materials can be conveyed to the position corresponding to the auger feed inlet.

[0050] As another preferred embodiment, a first sorting mechanism 60 is further arranged between the lifting mechanism 50 and the pushing auger 420. The first sorting mechanism 60 is a fruit diameter sorting sieve to screen the raw material oil-tea fruits 80 from the conveyor belt 530 by fruit diameter and then send them into the auger feed inlet. It should be noted that the number of the first sorting mechanism and the number of the fruit diameter sorting sieves should be determined according to actual needs. Please refer to the appendix of this application. Figure 1Or 3. Currently, only a schematic structural diagram of the structure below the fruit diameter sorting sieve is provided. It can be understood that the sieve hole sizes of each section of the fruit diameter sorting sieve can be set to the same diameter to ensure that the same level of camellia oleifera fruits 80 are screened out. By analogy, a secondary, tertiary, or multi-level fruit diameter sorting sieve can be set, and each section of the fruit diameter sorting sieve is correspondingly provided with structures such as the fruit shell cutting mechanism below the sorting sieve as Figure 1 The structures such as the fruit shell cutting mechanism below the sorting sieve. Those skilled in the art can directly understand this part and will not be elaborated here.

[0051] As a specific example, the number of the cutting assemblies 430 is two, and the two cutting assemblies 430 are relatively arranged on both sides of the auger discharge port. It can be understood that the number of the cutting assemblies 430 can also be set as required. For example, in another embodiment, the number of the cutting assemblies 430 is four, with two as a group, and the cutting directions of the two groups are perpendicular to each other. The two cutting assemblies 430 in each group are relatively arranged on both sides of the auger discharge port. It is easy to understand that the camellia oleifera fruits 80 cut in two directions will be more easily separated from the fruit shells. By analogy, those skilled in the art can arrange multiple groups of cutting assemblies 430 as required.

[0052] As a preferred embodiment, a second sorting mechanism 70 is further included. The second sorting mechanism 70 includes a fruit shell sorting sieve, a kernel collection mechanism, and a fruit shell collection device. The fruit shell sorting sieve is obliquely arranged on one side of the lower grinding disc mechanism 30. The upper end of the fruit shell sorting sieve is connected to the outlet position of the grinding space 340. The kernel collection device is communicated with the sieve holes of the fruit shell sorting sieve, and the fruit shell collection device is arranged at the lower end of the fruit shell sorting sieve.

[0053] Furthermore, the feed hole 220 is a rectangular hole, and the feed hole 220 is arranged deviating from the axis line of the pressure disc 210. In other embodiments, the feed hole can also be set in other shapes, such as a circular hole.

[0054] Working process: The raw material of camellia oleifera fruits 80 enters the first sorting mechanism 60 through the raw material hopper 510 under the conveying action of the conveyor belt 530. The same-level camellia oleifera fruits 80 sorted by the first sorting mechanism 60 enter the inside of the pushing auger 420 through the auger feed port, and are gradually pushed to the auger discharge port under the drive of the second driving mechanism 410. Through the cutting action of the grooving knife 431, a crack notch is cut on the fruit shell of the camellia oleifera fruit 80, and then it enters the grinding space 340 through the feed port on the pressure disc 210. The moving disc 310 is rotated by the drive of the first driving mechanism 10, and the weight of the pressure disc 210 is used to grind the camellia oleifera fruits 80 located in the grinding space 340, so as to realize the separation of the fruit shell. The separated kernels and fruit shells are sorted by the second sorting mechanism 70, so as to realize the separation and storage of the kernels and fruit shells.

[0055] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
