Description

Technical Field

[0001] This invention relates to the field of shelling equipment technology, specifically to a camellia fruit shelling machine. Background Technology

[0002] Camellia oleifera fruit consists of a shell and seeds. In the process of extracting camellia oil, the shell must first be removed to obtain the camellia seeds, and then the oil is extracted through pressing and other processes. However, the size of camellia oleifera fruit is affected by multiple factors such as region, climate conditions, and degree of ripeness, resulting in significant differences in the outer diameter of fresh fruit, as well as inconsistent thicknesses of the shell and seeds, which poses a considerable challenge to the shelling process.

[0003] Currently, the shelling of camellia oleifera fruits still relies mainly on traditional methods, such as sun-drying to induce the shells to crack naturally before manually extracting the seeds, or manual peeling. These methods are not only labor-intensive and inefficient, but also difficult to meet the needs of large-scale processing. Although some processing stages have introduced general-purpose shelling equipment, existing equipment generally lacks adaptability to changes in fruit diameter, making it difficult to effectively handle camellia oleifera fruits of different sizes. Especially when dealing with unripe fruits (not fully mature fruits), the shelling effect is even worse, easily causing seed damage or incomplete separation of shell and seed, seriously affecting the subsequent processing quality and oil yield.

[0004] In conclusion, there is an urgent need for a camellia fruit peeling machine to solve the problems existing in the current technology. Summary of the Invention

[0018] To facilitate understanding of the present invention, a more complete description is provided below, along with preferred embodiments. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0020] Example: See Figure 1This embodiment provides a camellia fruit peeling machine, including a feeding device 1, a peeling device 2, and a separating device 3. The feeding device 1 is used to transport the camellia fruit to the peeling device 2 for peeling. The separating device 3 is located downstream of the peeling device 2 and is used to separate the shell from the seeds.

[0021] like Figures 2-7 As shown, the shelling device 2 includes a frame 21 and a screening assembly 22, a shelling assembly 23 and a conveying assembly 24 arranged sequentially from top to bottom on the frame 21; The screening assembly 22 includes a feed hopper 221 and a screening drum 225. The screening drum 225 includes multiple screening sections arranged sequentially along the axial direction. The screening particle size of each screening section gradually increases from the first end to the second end of the screening drum 225. The feed hopper 221 is fixedly installed on the frame 21 and its outlet is connected to the first end of the screening drum 225. The outlet of each screening section and the outlet of the second end of the screening drum 225 are all connected to a peeling assembly 23. The conveying assembly 24 is located below the discharge port of each shelling assembly 23 and is used to convey the shells and seeds to the downstream separation device.

[0022] In this embodiment, the shelling device can grade the camellia fruit according to its outer diameter through the screening sections of the screening drum 225 and the discharge port at the second end. The camellia fruit graded according to its outer diameter is then shelled by the corresponding shelling component 23. The mixture output by the shelling component 23 (i.e., the mixture of seeds and shells) is then sent to the downstream separation device through the conveying component 24 to separate the shells from the seeds.

[0023] See Figure 3 The screening drum 225 includes spokes 2251, screen bars 2252, spiral blades 2253, and a rotating shaft 2254. Multiple spokes 2251 are spaced apart on the rotating shaft 2254, and multiple screen bars 2252 are equally spaced circumferentially between adjacent spokes 2251 to form a screening section. Spiral blades 2253 are provided within the screening section, and the spokes 2251 have material passages. Through the material passages on the spokes 2251, camellia oleifera fruits can enter the screening drum 225 from the first end, enter the next screening section from the current screening section, and finally, oversized camellia oleifera fruits can be discharged from the second end of the screening drum 225. The spiral blades 2253 allow the camellia oleifera fruits to move axially within the screening section, enabling camellia oleifera fruits that cannot be screened out from the current screening section to enter the next screening section with a larger particle size.

[0024] From the first end to the second end of the rotating shaft 2254, the circumferential spacing between adjacent screen bars 2252 in each screening section gradually increases, that is, from the first end to the second end, the screening particle size of each screening section gradually increases; the circumferential spacing between adjacent screen bars 2252 is the set screening particle size. If the outer diameter of the camellia fruit is smaller than the circumferential spacing of the current screen bar, it can fall into the corresponding peeling component 23 through the gap between the screen bars. If the outer diameter of the camellia fruit is larger than the circumferential spacing of the current screen bar, it cannot fall into the peeling component below from the current screening section, and can only be conveyed to the next level screening section by the spiral blades 2253.

[0025] Furthermore, the first and second ends of the rotating shaft 2254 are rotatably mounted on the frame 21. The first end of the rotating shaft 2254 passes through the feed hopper 221, and the outlet of the feed hopper 221 is connected to the material passage on the spoke 2251 closest to the first end, so that the material in the feed hopper 221 enters the screening drum 225.

[0026] like Figure 3 As shown, this embodiment has three screening sections. Since the spokes 2251 at the second end also allow camellia fruit to pass through, it can achieve screening of camellia fruit in four outer diameter grades: small, medium, large, and extra-large. After the camellia fruit enters the screening drum 225 from the first end through the feed hopper 221, it moves towards the second end due to the rotation of the screening drum 225 and the conveying action of the spiral blades 2253. During the movement of the camellia fruit towards the second end, the screening particle size of the three screening sections gradually increases. Therefore, the first screening section will screen out camellia fruit with small outer diameter, the second screening section will screen out camellia fruit with medium outer diameter, and the third screening section will screen out camellia fruit with large outer diameter. The remaining extra-large camellia fruit cannot fall into the next-stage peeling component from the third screening section. Instead, it can only enter the next-stage peeling component from the feed port of the spokes at the second end under the push of the spiral blades. Thus, screening of four outer diameter grades (small, medium, large, and extra-large) is achieved.

[0027] In this embodiment, the problem of oversized camellia fruits being unable to be screened out is solved by the material passage of the second end plate. Since the outer diameter of the camellia fruits is inconsistent, there may be camellia fruits that cannot be screened out even in the third screening section. If there is no material passage of the second end plate, the oversized camellia fruits will always remain inside the screening drum, affecting the normal screening effect of the device.

[0028] like Figure 2As shown, the screening component 22 also includes a feeding hopper 223 disposed on the frame 21. A feeding hopper 223 is provided below each screening section and below the material passage of the spoke 2251 closest to the second end. Each feeding hopper 223 is connected to the corresponding shelling component 23 through a receiving hopper 224. The feeding hopper 223 and the receiving hopper 224 are movably connected.

[0029] The different outer diameter grades of camellia fruits screened out are conveyed to the corresponding shelling components 23 for shelling through the feeding hopper 223 and the receiving hopper 224. The feeding hopper 223 and the receiving hopper 224 are movably connected, which allows for flexible disassembly between the receiving hopper 224 and the shelling components 23, making it convenient for maintenance and repair of the shelling components.

[0030] Specifically, the hopper 223 is provided with a sliding groove 2231 and a hanging groove 2232. The sliding groove 2231 is arranged vertically, and the hanging groove 2232 is arranged at an angle and is located above the sliding groove 2231. The upper end of the hanging groove 2232 is connected to the sliding groove 2231. The receiving hopper 224 is arranged inside the hopper 223 and is provided with a hanging ear pin on its upper part. The hanging ear pin is slidably arranged in the sliding groove 2231.

[0031] During normal operation, the receiving hopper 224 is positioned at the lower end of the chute 2231. Since the receiving hopper is mounted in the chute 2231 via a hanging pin, it can rotate relative to the discharge hopper 223 to ensure smooth docking with the shelling assembly 23. When the shelling assembly 23 requires maintenance or repair, the hanging pin of the receiving hopper 224 is positioned in the suspension groove 2232. At this time, the receiving hopper is disconnected from the shelling assembly 23 and suspended, allowing operators to perform maintenance or repair work on the shelling assembly 23.

[0032] like Figure 2 and Figure 4 As shown, the screening assembly 22 also includes a protective cover 222. The protective cover 222 includes a semi-circular end plate 2221 and a semi-circular protective cover 2223. The semi-circular protective cover 2223 is disposed on the frame 21 and covers the upper half of the screening drum 225. The end of the semi-circular protective cover 2223 near the second end of the rotating shaft 2254 is provided with a semi-circular end plate 2221, and the end near the first end of the rotating shaft 2254 is provided with a semi-circular opening 2222 or a semi-circular end plate 2221.

[0033] Specifically, the semi-circular end plate 2221 or semi-circular opening 2222 is provided at the end of the semi-circular cover 2223 near the first end of the rotating shaft 2254. This depends on the structural shape of the feed hopper 221. When the discharge port of the feed hopper 221 is a complete circular structure that connects with the first end of the screening drum, a semi-circular opening 2222 should be provided to avoid the feed hopper 221. When the discharge port of the feed hopper 221 is a semi-circular structure that connects with the first end of the screening drum, a semi-circular end plate 2221 can be provided, that is, the discharge port of the feed hopper 221 connects with the lower half of the first end of the screening drum, without the need to avoid the feed hopper.

[0034] like Figures 5-7 As shown, the shelling assembly 23 includes a cover 231, a shelling cylinder 233, a shelling roller assembly 235, and a shelling screen 237. The shelling screen 237 is semi-circular and is installed inside the shelling cylinder 233. The shelling cylinder 233 has a discharge port below the shelling screen 237. The shelling roller assembly 235 is rotatably mounted on the shelling cylinder 233, and its lower half is located in the shelling screen 237. The cover 231 is detachably mounted on the shelling cylinder 233 and covers the upper half of the shelling roller assembly 235. The upper part of the cover 231 has a feed inlet to connect with the receiving hopper 224.

[0035] Specifically, the peeling screen 237 has several peeling holes. The diameter of the peeling holes should be set according to the outer diameter of the camellia fruit entering it, to ensure that unpeeled camellia fruits do not fall into the next stage conveying component, while allowing peeled camellia seeds to pass through the peeling holes into the next stage conveying component. The peeling roller assembly 235 includes a central rotating shaft, end plates, and peeling columns. The two ends of the central rotating shaft are rotatably mounted on the peeling cylinder 233. Two end plates are spaced apart on the central rotating shaft, and the end plates are fixedly connected to the central rotating shaft. Multiple peeling columns are spaced circumferentially between the two end plates. A drive wheel 236 is provided at one end of the central rotating shaft protruding from the peeling cylinder 233. After the camellia fruit enters the peeling assembly 23, the rotating peeling roller assembly 235, in conjunction with the peeling holes, squeezes the shell on the surface of the camellia fruit, separating the outer shell from the seed, thus achieving the purpose of peeling off the outer shell of the camellia fruit.

[0036] Furthermore, the cover 231 is detachably mounted on the peeling cylinder 233, specifically as follows: Figure 5 and Figure 6As shown, both the peeling cylinder 233 and the cover 231 have openings on both sides. A tensioning screw 234 is hinged in the opening of the peeling cylinder 233. The tensioning screw 234 can rotate outward from the peeling cylinder 233. After the cover 231 is placed on the peeling cylinder 233, the openings of the two are aligned. By rotating the tensioning screw 234, the tensioning screw is simultaneously located in the openings of the cover 231 and the peeling cylinder 233. Finally, a clamping member 232 is screwed into the upper part of the tensioning screw 234. The clamping member 232 is threadedly connected to the tensioning screw 234. As the clamping member 232 is screwed, it can clamp the cover 231, thereby fixing the cover 231 to the peeling cylinder 233.

[0037] Of course, the peeling component described in some embodiments may also adopt other forms of structure, which will not be listed one by one in this embodiment.

[0038] Furthermore, the conveying assembly 24 includes a conveyor belt, a driving roller, a driven roller, and a separator plate. The two ends of the conveyor belt are respectively provided with a driving roller and a driven roller. The working surface of the conveyor belt is provided with separator plates at intervals along the conveying direction. The conveying section of the conveyor belt is provided with baffle plates on both sides. That is, two adjacent separator plates and the baffle plates on both sides of the conveying section form a square space to accommodate seeds and shells, which can effectively prevent round seeds from moving too freely on the conveyor belt and affecting the normal conveying of materials.

[0039] like Figures 8-9 As shown, the feeding device 1 includes a support frame 11, a feeding assembly 12, and a hopper assembly 13. The feeding assembly 12 and the hopper assembly 13 are both mounted on the support frame 11. The hopper assembly 13 is located at the receiving end of the feeding assembly 12. The lower part of the support frame 11 is provided with wheels. The feeding assembly 12 includes a driving roller assembly 123, a driven roller assembly 124, and a feeding belt 121. The driving roller assembly 123 and the driven roller assembly 124 are respectively located at both ends of the feeding belt 121. Partitions 122 are spaced apart along the conveying direction on the working surface of the feeding belt 121. Furthermore, baffles are provided on both sides of the conveying section of the feeding belt 121. Two adjacent partitions 122 and the baffles on both sides can form a square conveying space, effectively preventing the camellia fruit from falling.

[0040] like Figure 9As shown, the hopper assembly 13 includes a hopper body 131, an insert plate 132, and a discharge baffle 133. The discharge port of the hopper body 131 is located directly above the feeding belt 121. The insert plate 132 is slidably inserted into the discharge port from the side downstream of the feeding direction. The sliding direction of the insert plate 132 is in the same direction as the feeding direction. The fixed end of the discharge baffle 133 is fixedly connected to the side of the discharge port upstream of the feeding direction. The free end of the discharge baffle 133 is located below the insert plate 132.

[0041] Preferably, in this embodiment, the feeding baffle is a beef tendon baffle. The feeding speed can be controlled by the cooperation of the insert plate 132 and the feeding baffle 133, so as to ensure that the feeding speed of the feeding device 1 matches the shelling speed of the shelling device 2.

[0042] Preferably, in this embodiment, the screening roller 225 is driven by drive component four 27, the peeling roller group 235 is driven by drive component two 25, the active roller of the conveying component 24 is driven by drive component three 26, and the active roller assembly 123 of the feeding component 12 is driven by drive component one 14; the drive component one 14, drive component two 25, drive component three 26 and drive component four 27 can be electric motors or hydraulic motors.

[0043] In this embodiment, the separation device 3 is a toothed roller separator, which is existing technology in the field. For example, Chinese patent application number CN202011641125.4 discloses a camellia fruit peeling and seed shell separation device, so it will not be described in detail in this embodiment.

[0044] It should be noted that the peeling device 2 in this embodiment does not necessarily have to be used in conjunction with the feeding device 1 and the separating device 3. The peeling device 2 can be used alone in a peeling production line to complete the peeling of camellia fruit, or the peeling device 2 in this embodiment can be used according to actual usage needs.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
