Description
Technical Field
[0001] This utility model relates to the field of torreya nut peeling technology, and in particular to a torreya nut peeling device. Background Technology
[0002] Torreya grandis is a high-quality spindle-shaped nut. Kuaiji Mountain in Zhejiang Province is a typical Torreya grandis producing area. The Torreya grandis trees on the mountain are over a thousand years old, and the trees gradually descend downwards. Every year, Torreya grandis farmers plant or replenish the trees. Every year during the harvest season, the farmers pick the green fruits from the Torreya grandis trees, remove the outer green skin, and take out the inner nut. Then, the Torreya grandis of different diameters are sorted according to established standards and sold to the corresponding buyers, or they roast and package them for wholesale or retail.
[0003] Most existing torreya nut peeling devices rely on manual peeling, which is not only inefficient but also prone to damaging the nuts, affecting their quality and price. Furthermore, existing peeling devices often cannot accommodate torreya nuts of different diameters, requiring multiple manual adjustments and sorting, increasing labor intensity and costs.
[0004] Therefore, how to provide a device that can efficiently, automatically, and non-destructively remove the outer skin of Torreya grandis to meet the needs of Torreya grandis farmers and buyers has become a technical problem that urgently needs to be solved by those skilled in the art.

[0043] See Figure 1-3 As shown, this embodiment provides a peeling device for Torreya grandis, comprising:
[0044] Casing 100;
[0045] The feeding assembly is located at the top of the housing 100;
[0046] The grading component is inclined downward in the horizontal direction at the bottom of the feeding component, and the grading component is detachably connected to the inner wall of the housing 100.
[0047] The shell-breaking component is located at the bottom of the grading component;
[0048] A screening component is located below the shell-breaking component, and the screening component is detachably connected to the inner wall of the shell 100;
[0049] The collection components are located at the bottom of the housing 100.
[0050] It is understood that the torreya nut peeling device provided in this embodiment can automatically grade, crack, screen, and collect torreya nuts, greatly improving the efficiency and automation of torreya nut peeling. The grading component allows for grading according to the size of the torreya nuts, enabling different sizes to be cracked separately, avoiding poor cracking results due to uneven nut size. Simultaneously, the cracking component effectively cracks the torreya nuts, and by adjusting the spacing between the cracking rollers and the number of serrations on the cracking protrusions, it can accommodate torreya nuts of different sizes, further improving the cracking effect. The screening component filters the cracked torreya nuts, removing those that are not fully cracked, ensuring peeling quality. Finally, the collection component facilitates the collection and processing of the peeled torreya nuts, improving the overall practicality of the peeling device. Furthermore, the peeling device has a simple structure, is easy to disassemble and clean, facilitating daily maintenance and reducing operating costs.
[0051] Specifically, the feeding assembly includes:
[0052] The feed hopper 111 is located on the top of one side of the housing 100;
[0053] A vibrator is installed on the side wall of the feed hopper 111 and is connected to the feed hopper 111 to vibrate the feed hopper 111.
[0054] Understandably, the vibrator ensures that the torreya nuts are evenly distributed within the feed hopper 111, preventing blockages and accumulation during feeding and guaranteeing smooth and uniform feeding. Simultaneously, the vibrator promotes rolling and grading of the torreya nuts on the grading components, improving grading efficiency and accuracy.
[0055] Specifically, the hierarchical components include:
[0056] The first grading bin 121 is located at the bottom of the feed bin 111. The top of the first grading bin 121 is inclinedly provided with a first grading plate 122. Both the front and rear ends of the first grading plate 122 are detachably connected to the inner wall of the shell 100.
[0057] The second grading compartment 123 is located on one side of the first grading compartment 121. The top of the second grading compartment 123 is inclinedly provided with a second grading plate 124. Both the front and rear ends of the second grading plate 124 are detachably connected to the inner wall of the housing 100.
[0058] The third grading compartment 125 is located on one side of the second grading compartment 123. The top of the third grading compartment 125 is inclined with a third grading plate 126. Both the front and rear ends of the third grading plate 126 are detachably connected to the inner wall of the housing 100.
[0059] Understandably, the arrangement of the first grading plate 122, the second grading plate 124, and the third grading plate 126 enables multi-level grading of Torreya nuts. Torreya nuts of different sizes roll into their corresponding grading bins as they pass through the grading plates, thus achieving precise grading. This grading method not only improves grading efficiency but also ensures the consistency and stability of subsequent shell-breaking processes. Furthermore, the detachable connection between the grading plates and the inner wall of the shell 100 facilitates the cleaning and replacement of the grading components, reducing maintenance costs. In addition, the inclined design of the grading components promotes smooth rolling of the Torreya nuts during the grading process, preventing jamming and accumulation.
[0060] Specifically, the end of the first grading plate 122 that is away from the second grading plate 124 extends out of the housing 100.
[0061] Specifically, the aperture of the first grading plate 122 is smaller than the aperture of the second grading plate 124, and the aperture of the second grading plate 124 is smaller than the aperture of the third grading plate 126.
[0062] Understandably, the different aperture sizes on the first grading plate 122, the second grading plate 124, and the third grading plate 126 ensure that nuts of different sizes fall precisely into their corresponding grading bins. This progressively smaller aperture design not only improves grading accuracy but also makes the entire grading process more efficient and orderly. Simultaneously, the design of the end of the first grading plate 122 extending beyond the housing 100 from the second grading plate 124 allows the graded nuts to smoothly roll into the next grading component or shell-breaking component, avoiding problems such as jamming or accumulation due to improper design. Furthermore, this peeling device also considers ease of use and flexibility. The detachable connection between the grading components, screening components, and the inner wall of the housing 100 not only facilitates daily cleaning and maintenance but also allows these components to be replaced or upgraded according to actual needs, improving the adaptability and service life of the entire peeling device.
[0063] Specifically, the hierarchical components also include:
[0064] The first partition plate 127 is vertically disposed between the first grading plate 122 and the second grading plate 124, and the two sides of the first partition plate 127 are slidably connected to the inner wall of the housing 100.
[0065] The second partition plate 128 is vertically disposed between the second grading plate 124 and the third grading plate 126, and the two sides of the second partition plate 128 are slidably connected to the inner wall of the housing 100.
[0066] Understandably, when the torreya nuts to be graded enter from the feed hopper 111, the first partition plate 127 slides upward, at which point the top of the first partition plate 127 is higher than the bottom of the first grading plate 122, and the torreya nuts enter the first grading hopper 121. If no torreya nuts to be graded enter the first grading hopper 121 for a continuous period of time, the first partition plate 127 slides downward, at which point the top of the first partition plate 127 is at the same height as the first grading plate 122. The torreya nuts in the first grading hopper 121 are graded on the first grading plate 122. Depending on the size of the torreya nuts, some will fall through the holes in the first grading plate 122 into the lower second grading hopper 123, while larger torreya nuts will continue to roll within the first grading hopper 121. Similarly, the second separator 128 serves a similar function. When no torreya nuts enter the second grading chamber 123, the second separator 128 slides downwards, allowing the torreya nuts in the second grading chamber 123 to fall into the third grading chamber 125 through the holes in the second grading plate 124. This design not only improves grading efficiency but also avoids the problem of torreya nut accumulation during the grading process. Furthermore, the sliding connection allows the separators to be adjusted according to actual needs, increasing the flexibility and practicality of the entire peeling device.
[0067] In this embodiment, the top of the first partition plate 127 and the top of the second partition plate 128 are provided with an inclination angle, which matches the inclination angle of the grading plate to facilitate the smooth rolling of the torreya nuts during the grading process. This design not only further reduces the jamming and accumulation of torreya nuts during the grading process, but also improves the grading efficiency and accuracy.
[0068] Specifically, the hatching components include:
[0069] There are two first shell-breaking rollers 131. The two first shell-breaking rollers 131 are arranged in parallel at the bottom of the first grading chamber 121. A first gap is provided between the two first shell-breaking rollers 131. A plurality of first shell-breaking protrusions 132 are provided on the outer wall of the first shell-breaking rollers 131. A plurality of first serrations 133 are provided on the outer wall of the shell-breaking protrusions.
[0070] There are two second shell-breaking rollers 134. The two second shell-breaking rollers 134 are arranged in parallel at the bottom of the second grading bin 123. A second gap is provided between the two second shell-breaking rollers 134. A number of second shell-breaking protrusions are provided on the outer wall of the second shell-breaking rollers 134. A number of second serrations are provided on the outer wall of the second shell-breaking protrusions.
[0071] There are two third shell-breaking rollers 135. The two third shell-breaking rollers 135 are arranged in parallel at the bottom of the third grading bin 125. A third gap is provided between the two third shell-breaking rollers 135. A number of third shell-breaking protrusions are provided on the outer wall of the third shell-breaking rollers 135. A number of third serrations are provided on the outer wall of the third shell-breaking protrusions.
[0072] Understandably, the arrangement of the first shelling roller 131, the second shelling roller 134, and the third shelling roller 135 allows for the separate shelling of different sizes of torreya nuts after grading. As torreya nuts of different sizes pass through their respective shelling rollers, they are subjected to the action of the shelling protrusions and serrations on the rollers, thus achieving effective shelling. Furthermore, by adjusting the spacing between the different shelling rollers and the number of serrations on the shelling protrusions, it is possible to accommodate torreya nuts of different sizes, ensuring the consistency and stability of the shelling effect. This grading shelling method not only improves shelling efficiency but also guarantees the quality of peeling.
[0073] Specifically, the first spacing is smaller than the second spacing, and the second spacing is smaller than the third spacing.
[0074] Understandably, the progressively increasing spacing of the first, second, and third gaps corresponds to the progressively decreasing aperture design of the grading plates in the grading assembly, ensuring that the graded torreya nuts are precisely matched to the corresponding shelling rollers. This design not only improves the coordination and efficiency of the entire peeling device but also avoids poor shelling results due to size mismatch. Simultaneously, the addition of shelling protrusions and serrations increases friction and shearing forces during the shelling process, allowing the torreya nut shells to be peeled off more effectively, further improving peeling quality. Furthermore, the parallel arrangement of the shelling rollers ensures stability and uniformity during the shelling process, preventing uneven shelling or damage to the internal structure of the torreya nuts caused by roller tilting or misalignment.
[0075] Specifically, the filtering components include:
[0076] Screening mesh 141 is located below the shell-breaking component;
[0077] Vibrating screen 152 is set below screening screen 141. Vibrating screen 152 is connected to screening screen 141 and is used to screen screen 141.
[0078] Understandably, the screening mesh 141 and vibrating screen 152 allow for further screening of the shelled torreya nuts. The screening mesh 141 is designed to allow successfully shelled torreya nuts to pass through, while blocking those that are not fully shelled or still have their shells intact. Subsequently, the activation of the vibrating screen 152 causes the screening mesh 141 to vibrate. This vibration not only helps to further crack the shells of the blocked torreya nuts but also promotes the smooth falling of the shelled torreya nuts into the collection assembly below. This screening method not only improves screening efficiency but also ensures the quality of the shelled torreya nuts, avoiding subsequent processing difficulties caused by incomplete screening.
[0079] Specifically, the collection components include:
[0080] The collection bin 151 is located at the bottom of the housing 100. The top opening of the collection bin 151 is connected to the bottom of the housing 100, and the bottom of the collection bin 151 is provided with a discharge port.
[0081] Understandably, the collection bin 151 allows for convenient and unified collection and storage of peeled torreya nuts. The top opening of the collection bin 151 connects to the bottom of the casing 100, ensuring that the peeled torreya nuts fall smoothly into it. Simultaneously, the discharge port at the bottom of the collection bin 151 facilitates the user's removal and use of the torreya nuts according to actual needs. This collection method not only improves the practicality and convenience of the entire peeling device but also helps users further process and utilize the peeled torreya nuts.
[0082] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
