Description

Technical Field

[0001] This invention relates to the field of camellia fruit crushing and screening technology, and in particular to a device for crushing and multi-stage vibrating screening of camellia fruit. Background Technology

[0002] Camellia oleifera is one of the world's four major woody oil crops. Along with oil palm, olive, and coconut, it is considered one of the world's four major woody edible oil plants. It grows in the high mountains and hilly areas of the subtropical region of southern China and is a unique, high-grade natural oil crop native to China. Camellia oleifera fruit contains over 30% oil, used for food, hair conditioner, and medicine. It can be used to make candles and soaps, and can also be used as a substitute for engine oil. Camellia oleifera has high comprehensive utilization value. The seed meal contains tea saponins, tea seed polysaccharides, and tea seed protein, all of which are raw materials for chemical, light industrial, food, and feed industries. The seed shells can also be used to make furfural and activated carbon. During the processing of camellia oleifera fruit, crushing and drying are necessary. The design and experimental research of a shell-crushing camellia oleifera fruit coarse separator revealed that the average diameter of the fruit is mainly distributed in the range of 25-40 mm; the main length of the seeds is mainly distributed in the range of 10-20 mm; and the shell size ranges from 20-35 mm in length and 5-30 mm in width. Existing camellia fruit shelling equipment exhibits significant shortcomings in achieving efficient shelling and ensuring effective separation of shells and seeds. Current technologies separate these two steps, involving a crushing device and a screening device for the crushed camellia fruit shells and seeds. This results in low processing efficiency and necessitates the purchase of multiple machines, leading to high processing costs. Furthermore, the screening device's simplistic structure results in insufficient screening effectiveness. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0050] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0051] See Figure 1-17The present invention discloses a device for crushing and multi-stage vibrating screening of camellia fruit, comprising a frame 1, a crushing device 2 on the upper side of the frame 1, and a screening device 4 on one side of the crushing device 2 and located on the upper side of the frame 1; the crushing device 2 includes a feed hopper 20, a feeding conveyor belt 25, and a crushing assembly; the feed hopper 20 is disposed on the frame 1, and its upper end face has a through discharge port 200; the feeding conveyor belt 25 is disposed at the lower opening of the discharge port 200, and the crushing assembly is disposed at one end of the feeding conveyor belt 25; the screening device 4 includes a primary screening cylinder 40, a secondary screening cylinder 8, and a protective shell 3; the protective shell 3 is disposed on the frame 1, and the primary screening cylinder 40 is disposed on the protective shell 3, with multiple sets of primary screening holes extending through its inner side. The device comprises a primary screening chamber, an inner side of which is provided with a secondary screening cylinder 8. One end face of the secondary screening cylinder 8 forms an outward-facing secondary screening chamber. The inner side wall of the secondary screening chamber is provided with multiple sets of through-holes. A transfer component 24 is connected at one end to one end of the crushing component and at the other end to one end of the screening device 4. The other end of the screening device 4 is provided with a discharge channel 5. A drive component 7 is mounted on the frame 1 and located at the outer edge of the protective shell 3. The drive component is connected to both ends of the primary screening cylinder 40 to drive the primary screening cylinder 40 to rotate. The outer side wall of the secondary screening cylinder 8 is provided with at least one set of return pipes 9 that communicate with the inner side of the secondary screening chamber. In operation, the camellia fruit to be processed is fed into the feed hopper 20 and continuously conveyed to the crushing component by the conveyor belt 25 on the lower side. This crushing separates the camellia seeds from the fruit peel. The fruit is then transferred to the screening device 4 by the transferor 24. The screening device 4 is open at both ends; one end is the feed inlet connected to the transferor, and the other end is the discharge outlet connected to the discharge channel 5, which discharges the camellia peel. When the transferor 24 rotates the crushed camellia fruit to the screening device 4, it first enters the secondary screening chamber of the secondary screening cylinder 8. It undergoes a first screening through the secondary screening holes formed on the secondary screening cylinder 8, allowing smaller camellia seeds to enter the primary screening cylinder 40 for a second screening before falling to the lower side of the protective shell 3. At this time, the secondary screening cylinder 8 still contains larger camellia seeds and fruit peel. The drive component continuously drives the primary screening cylinder 40 to rotate the secondary screening cylinder 8, further achieving the screening purpose. Furthermore, the larger camellia seeds and fruit peels remaining in the secondary screening cylinder 8 are guided to the primary screening cylinder 40 for further screening through the set return pipe 9. Finally, the camellia seeds fall downwards, and the camellia fruit peels are discharged from the other end of the primary screening cylinder 40 to the discharge channel 5, which effectively avoids excessive accumulation of camellia seeds and fruit peels inside the primary screening cylinder 40, which could cause blockage and affect the screening effect.

[0052] See Figure 8-12Specifically, two sets of screening dividing plates 400 are provided between the primary screening cylinder 40 and the secondary screening cylinder 8. The screening dividing plates 400 divide the primary screening cavity into independent first-class screening cavities 44, second-class screening cavities 45, and third-class screening cavities 47. The screening dividing plates 400 divide the inner side of the primary screening cavity into multiple independent first-class screening cavities 44, second-class screening cavities 45, and third-class screening cavities 47. The formed first-class screening cavities 44, second-class screening cavities 45, and third-class screening cavities 47 are respectively provided with first-class primary screening holes 404 on the inner sidewall of the first-class screening cavity 44, second-class primary screening holes 405 on the inner sidewall of the second-class screening cavity 45, and third-class primary screening holes 407 on the inner sidewall of the third-class screening cavity 47. The inner sidewall of the formed secondary screening cavity is provided with first-class secondary screening holes 80, second-class secondary screening holes 92, and third-class secondary screening holes 93 with gradually increasing diameters, facing the connecting support plate 94. The first-class secondary screening holes 80 are interconnected with the first-class screening cavity 44, the second-class secondary screening holes 92 are interconnected with the second-class screening cavity 45, and the third-class secondary screening holes 93 are interconnected with the third-class screening cavity 47. When the fruit berries that have passed through the first-grade secondary screening hole 80 in the secondary screening chamber are small in diameter, they fall directly into the protective shell for collection through the larger-diameter first-grade primary screening hole 404 inside the first-grade screening chamber 44. When the fruit berries that have passed through the second-grade secondary screening hole 92 in the secondary screening chamber are medium in diameter, they are screened in the second-grade screening chamber 45 in the first-grade screening chamber, and then fall directly into the protective shell for collection through the second-grade primary screening hole 405. When the fruit berries that have passed through the third-grade secondary screening hole 93 in the secondary screening chamber are large in diameter, they are screened in the third-grade screening chamber 47 in the first-grade screening chamber, and then fall directly into the protective shell for collection through the third-grade primary screening hole 407. Finally, the separated fruit peels are discharged through the other end of the first-grade screening chamber 40 to the discharge channel 5. Of course, to prevent the camellia seeds and peels at the outlet of the primary screening cylinder 40 from being screened in the tertiary screening chamber 47, a buffer plate 49 is installed at the opening of the primary screening cylinder 40 near the discharge channel 5. The end face of the buffer plate 49 is provided with multiple sets of through-feed ports 409 to facilitate the discharge of camellia peels to the discharge channel 5 for collection. On the outer side wall of the primary screening cylinder 40, the primary screening chamber 44 and the secondary screening chamber 45 are separated by a protruding limiting part 46, and the secondary screening chamber 45 and the tertiary screening chamber 47 are also separated by a protruding limiting part 46. The end face of the screening dividing plate 400 also needs to be provided with through-feed screening dividing holes with a diameter larger than that of the primary screening holes to facilitate the flow of camellia peels towards the discharge channel 5 between two adjacent screening chambers.

[0053] See Figure 12 Specifically, one end of the reflux pipe 9 is connected to the inner side of the secondary screening cavity 45, and a screening guide turbine blade 91 is provided at the opening. The screening guide turbine blade 91 improves the guiding effect of the reflux pipe on camellia seeds and camellia peel.

[0054] Specifically, multiple sets of connecting support plates 94 are provided between the outer sidewall of the secondary screening cylinder 8 away from the opening of the secondary screening cavity and the inner sidewall of the primary screening cavity. The connecting support plates 94 fix the secondary screening cylinder 8 to the inner sidewall of the primary screening cavity, so that a certain gap is formed between the outer sidewall of the secondary screening cylinder 8 and the primary screening cavity, so as to avoid affecting the screening effect.

[0055] See Figure 3 Specifically, a feeding centrifugal disc 41 is provided at the connection between the primary screening cylinder 40 and the screening device 4. A feeding guide turbine blade 43 is provided on the inner side of the opening of the feeding centrifugal disc 41. The turbine blade 43 is connected to the opening of the secondary screening cavity to ensure that the crushed camellia fruit can enter the secondary screening cylinder 8 for primary screening. The feeding guide turbine blade 43 enhances the guiding effect, and the flow between the feeding guide turbine blades 43 further improves the separation effect of camellia seeds and camellia fruit peel. A first annular protrusion ring 401 is provided on the outer sidewall of the feeding centrifugal disc 41 for easy connection with the drive assembly. A discharge centrifugal disc 42 is provided between the primary screening cylinder 40 and the discharge channel 5. The discharge centrifugal disc 42 facilitates the entry of the separated camellia fruit peel into the discharge channel 5. A second protrusion ring 402 is provided on its outer sidewall for easy connection with the drive assembly.

[0056] Referring to 3-6, the protective shell includes a lower shell 6, which is mounted on the frame 1. The upper end face forms a screening and collection cavity 63 with an outward opening. The inner bottom wall of the collection cavity 63 is provided with multiple sets of spaced-apart protruding collection dividing plates 62, and multiple sets of separation holes 65. The inner side wall is provided with multiple sets of discharge channels 60 communicating with the outside. The upper ends of the two side walls of the lower shell 6 form downward placement notches 61. The screening and collection cavity 63 formed by the lower shell 6 with an outward opening can serve as a collection shell for the screened camellia seeds. By setting multiple sets of collection dividing plates 62, preferably two sets, the collection cavity 63 is divided into three independent collection cavities 63, which can correspondingly collect camellia seeds of different diameters at the separation points of the first-grade screening cavity 44, the second-grade screening cavity 45, and the third-grade screening cavity 47. Finally, the seeds are discharged and collected through the discharge channels 60. Multiple sets of separation holes 65 are provided on the bottom wall of its inner cavity 63 to filter and separate finer dust, and its lower shell 6 is set in an open shape, wherein a dust collection tray 64 is slidably connected to the opening, and a handle 604 is provided on the outer side wall of the dust collection tray 64 for easy pulling.

[0057] The lower end face of the upper shell 34 is hinged to the upper end face of the lower shell 6, and the lower end face has a protective inner cavity 35 with an outward opening. The upper inner wall of the protective inner cavity 35 has multiple sets of spaced protruding fixing plates 33. The inner side wall of the protective inner cavity 35, on the side opposite to the connection between the upper shell 34 and the lower shell 6, has an observation port 31 that extends through both the inside and outside. A protective plate 30 is provided at the outer opening of the observation port 31. The lower end face of the upper shell 34, above the lower placement notch 61, has an upper placement notch 32. The upper shell 34 is located above the lower shell 6, and the two are connected by two sets of hinge locks 340, which allows the upper shell 34 to open and close relative to the lower shell 6. Meanwhile, a fixing plate 33 corresponding to the collecting and dividing plate 62 is provided inside the protective cavity 35 formed by the upper shell 34. The fixing plate 33 corresponding to the collecting and dividing plate 62 can limit the protruding limiting part 46 on the outer side wall of the primary screening cylinder 40 from top to bottom, ensuring the stability of the primary screening cylinder 40 when it rolls. The lower placement notch 61 and the upper placement notch 32 provided provide circumferential limiting for the formed feed centrifugal disc 41 and discharge centrifugal disc 42 to ensure the stability of the primary screening cylinder 40 when it rolls. The fixed rolling opening formed by the lower placement notch 61 and the upper placement notch 32 near the rotation 24 of the protective shell is higher than the fixed rolling opening formed by the lower placement notch 61 and the upper placement notch 32 near the discharge channel 5 of the protective shell, so that the entire primary screening cylinder 40 is tilted towards the discharge channel 5, which facilitates the rolling of the crushed camellia peel towards the discharge centrifugal disc 42.

[0058] See Figure 16-17Specifically, the driving assembly includes a driving carrier plate 700, which is disposed on the frame 1 and located at the opening of the lower placement notch 61; a driving motor 70, which is disposed on the driving carrier plate 700 and whose output end is rotatably connected to multiple sets of spaced transmission seats 73, with two adjacent sets of transmission seats 73 connected by a rotating rod 71; and a driving base 74, which is disposed on the driving carrier plate 700 and is provided with a drive gear 79, which is connected to the output end of the transmission seats 73. The driving base 71 and the first-stage screening cylinder 40 are provided with multiple sets of driving rollers 76 on their mating end face, and the outer surface of the driving rollers is provided with an inwardly recessed limiting groove 706. The drive carrier plate 700 serves as the base for the entire drive assembly. A drive motor 70, providing power, is mounted on the upper side. Two sets of drive bases 74 are placed opposite each other, and drive rollers 76, which are rotatably mounted on them and connected to the feed centrifugal disc 41, are provided. The outer surface of the drive rollers 76 has a concave limiting groove 706 to facilitate connection with the first annular protrusion ring 401. In use, the drive motor 70 drives the transmission seat 73 to rotate, which in turn drives the mutually connected drive gear 79 to rotate. A driven gear 790 is provided on the rear side of the drive rollers 76. When two drive rollers 76 are provided, each drive roller 76 is connected to driven gears 790 and 7009. The rotation of the drive gear 79 drives the driven gears 790 and the intermediate gears 709 and 700, which are provided between the drive gear 790 and the drive gear 79. The rotation of the drive gear 79 drives multiple driven gears 790 through gear meshing, which in turn drives the drive rollers 76 to rotate, thus driving the rotation of the primary screening cylinder 40. A drive assembly with the same structure is also provided at its discharge centrifugal disc 42. The second protruding ring 402 formed on the discharge centrifugal disc 42 is slidably connected to the limiting groove 706.

[0059] See Figure 13-15Specifically, the crushing shell 22 is located at the lower outlet of the feed hopper 20 and forms a crushing channel on its inner side. A motor base 21 is provided on the lower side of the crushing shell 22 and is located below the outlet of the feed hopper 20. A crushing drive motor 26 is provided on the crushing base 21. A crushing roller 27 is rotatably located at the outlet of the feed hopper 20 and at the output end of the feeding conveyor belt 25. A crushing floating plate 28 is located on the upper side of the crushing roller 27. A buffer spring 29 is provided between the crushing floating plate 28 and the inner upper wall of the outlet of the feed hopper 20. Multiple crushing grooves 208 are provided on the end face of the crushing floating plate 28 near the crushing roller 27. A cutting blade 280 is provided inside the crushing groove 208. The crushing drive motor 26 provides power for the rotation of the crushing roller 27 and the transmission of the material by the feeding conveyor belt 25. One end of the crushing drive motor 26 has a power output end 260, and one end of the crushing roller 27 forms a power receiving end 270. The power output end 260 and the crushing roller 27 are connected by a rotating belt or other common mechanical transmission. The rotating shaft of the feeding conveyor belt 25 forms a power receiving shaft 205, which is connected to the power output end 260 by a rotating belt or other common mechanical transmission. When the camellia fruit to be processed is introduced from the discharge port 200, it is transported by the feeding conveyor belt 25 to the inside of the crushing shell 22 to form a crushing channel. The crushing floating plate 28 and the crushing roller 27 are used to crush and separate the camellia seeds and fruit peel. The floating plate and the roller shaft cooperate to achieve a limiting function. The cutting function is provided by the cutting blade 280 on the floating plate. The floating function of this device is designed because the natural size of camellia fruits is not uniform. Without floating, small fruits would not be processed and large fruits would be damaged. The floating function is provided by a compression spring, and the float is connected by four long, light-emitting screws.
