Abstract

This invention discloses an apparatus for preparing de-astringent jujube seed powder using fermentation. The apparatus includes a storage mechanism, a first lifting mechanism, and a second lifting mechanism arranged at intervals. The top of the uppermost storage mechanism has a reserved space for each storage mechanism to be flipped, allowing for vertical movement and flipping. The lifting ends of the first and second lifting mechanisms are respectively equipped with a first connecting mechanism and a second connecting mechanism. Through the cooperation of the first connecting mechanism and the storage mechanisms, this invention allows the jujube seeds in multiple storage mechanisms to be flipped without opening the container.

Description

Technical Field

[0001] This invention relates to the field of fermentation equipment technology, specifically to an apparatus for preparing astringent jujube seed powder using fermentation. Background Technology

[0002] The purpose of preparing de-astringent jujube seed powder through fermentation is to decompose the astringent macromolecules in jujube seeds through microbial fermentation, while simultaneously enhancing the dissolution and activity of effective substances, thereby reducing astringency. Specifically, dry solid-state fermentation of jujube seeds can be directly mixed and inoculated with pre-treated dry jujube seed powder, requiring no additional activation steps. This simplifies the operation, making it suitable for small-scale production and adaptable to the low-moisture requirements of dry fermentation systems. Patent application CN224001406U discloses a fermentation and cultivation device for jujube kernels, which aims to achieve uniform mixing and constant temperature control during the fermentation process of jujube kernels, thereby improving the fermentation effect and product quality.

[0003] Based on existing technologies, the following problems exist: Existing dry solid-state fermentation devices for jujube kernels typically involve mixing jujube kernels and fermentation bacteria together in a fermentation container. The large accumulation of jujube kernels hinders oxygen contact, thus impeding fermentation. Opening and turning the fermentation container allows external bacteria to enter, potentially damaging the jujube kernels and causing incomplete fermentation in certain areas, affecting usability and the subsequent production of astringent-reducing jujube kernel powder. Referring to the aforementioned applications, wet fermentation of jujube kernels requires solid-liquid separation and drying after fermentation before producing astringent-reducing powder. This process is cumbersome and inefficient. To address these issues, a device for preparing astringent-reducing jujube kernel powder using fermentation is proposed. Summary of the Invention

[0004] The technical problem to be solved by this invention is to address the issue of uneven fermentation during the dry solid-state fermentation of jujube seeds, and to provide an apparatus for preparing de-astringent jujube seed powder using fermentation.

[0005] To address the aforementioned technical problems, this invention proposes an apparatus for preparing astringent-removing jujube seed powder using fermentation, comprising a box body and a frame fixedly disposed at the opening of the box body, with a door hinged to the side of the frame away from the box body, and further comprising: Storage mechanisms, arranged at intervals inside the box, are used to store jujube kernels for fermentation. The top of the uppermost storage mechanism has space reserved for individual rotation, allowing for vertical movement and rotation. A first mounting frame and a second mounting frame are fixed to both sides of the outer wall of the frame. A first lifting mechanism and a second lifting mechanism are respectively installed inside the first and second mounting frames. The lifting ends of the first and second lifting mechanisms are respectively equipped with a first connecting mechanism and a second connecting mechanism. The storage mechanism includes: A ring body is disposed inside a box. A first housing and a second housing are slidably disposed on the inner wall of the ring body so that the first housing and the second housing can move along the axial direction of the ring body. A rubber ring is fixedly disposed on the side of the first housing and the second housing that are close to each other. Limiting mechanisms for connecting with the first connecting mechanism and the second connecting mechanism are provided on both sides of the ring body. A driving device is provided on the first connecting mechanism and the second connecting mechanism. When the first connecting mechanism and the second connecting mechanism are connected to the corresponding limiting mechanism, the driving device can drive the corresponding limiting mechanism to rotate.

[0006] Furthermore, the storage mechanism also includes: An annular groove is formed at the middle of the inner wall and the middle of the outer wall of the rubber ring so that the rubber ring can bend along the annular groove after being compressed. The sealing plate is detachably installed on the top of the first housing, and there are two of them, with the two sealing plates located at opposite corners of the first housing; The mounting rod is slidably positioned at the center of the first and second housings, and both ends of the mounting rod are fixedly fitted with covers.

[0007] Furthermore, storage facilities also include: A first electromagnet is fixedly installed on the inner wall of the cover. A second electromagnet is sleeved on the inner wall of the cover. A sleeve is fixedly installed on the side of the second electromagnet away from the first electromagnet. The end of the sleeve away from the second electromagnet is fixedly connected to the side of the first housing and the second housing away from each other. A first spring is sleeved on the outer wall of the sleeve. A reinforcing plate is fixedly disposed on the side of the second electromagnet away from the first electromagnet and extends outside the cover. The side wall of the cover is provided with a first through groove for vertical movement of the reinforcing plate. One end of the reinforcing plate outside the cover is fixedly connected to the side of the first housing and the second housing away from each other, so as to connect to the second electromagnet from a position close to the outer wall of the first housing and the second housing.

[0008] Furthermore, the first shell and the second shell are arranged symmetrically with respect to the center point of the ring. The side walls and bottom of the first shell and the second shell are provided with spaced first guide holes, and the side walls of the rubber ring are provided with spaced second guide holes. Both the first electromagnet and the second electromagnet are designed in a ring shape, and the first electromagnet, the second electromagnet, and the sleeve are all fitted onto the side wall of the mounting rod.

[0009] Furthermore, the limiting mechanism includes: The limiting seat has a rotating component fitted at its internal center. One end of the rotating component inside the limiting seat is spherical, and the other end outside the limiting seat is cylindrical and fixedly connected to the outer wall of the ring. The side wall of the frame has a movable through groove, which is connected to the interior of the first mounting frame and the second mounting frame, respectively. The inner walls of both sides of the movable through groove have a first sliding groove, and a first slider is placed inside the first sliding groove. The side of the first slider that is close to each other is fixedly connected to the side wall of the limiting seat, and the side of the first slider that is far away from each other is fitted with a ball bearing.

[0010] Furthermore, the limiting mechanism also includes: A slot is formed on one side wall of the rotating part located inside the limiting seat and extends to the top of the limiting seat. A rod is fixedly provided at the bottom of the upper limiting seat. The rod can be inserted into the slot. A limiting groove is formed on one side wall of the rotating part located inside the limiting seat. The limiting groove is located on the side of the rotating part away from the ring body. A second through groove is formed on the side of the limiting seat away from the ring body. The inner diameter of the second through groove is larger than the inner diameter of the limiting groove.

[0011] Furthermore, the first lifting mechanism and the second lifting mechanism are identical, used to drive the first connecting mechanism and the second connecting mechanism to rise and fall respectively. The first lifting mechanism includes: A threaded rod is rotatably mounted on the inner wall of the first mounting frame. A threaded tube is threadedly connected to the side wall of the threaded rod. The outer wall of the threaded tube away from the frame is slidably connected to the inner wall of the first mounting frame. A first servo motor for driving the threaded rod to rotate is fixedly mounted on the top of the first mounting frame.

[0012] Furthermore, the first connecting mechanism includes: The connector is fixedly mounted on the outer wall of the threaded tube near the frame. A first groove is provided on the side of the connector away from the threaded tube. A second groove is provided on the inner wall of the first groove. The inner diameter of the second groove is larger than the inner diameter of the first groove.

[0013] Furthermore, the first connecting mechanism also includes: The third electromagnet is fixedly installed on the inner wall of the second groove. The inner wall of the second groove is fitted with a fourth electromagnet. Both the fourth and third electromagnets are ring-shaped. The inner wall of the fourth electromagnet is fixedly fitted with a connecting rod. One end of the connecting rod outside the connecting seat is fixedly fitted with a limiting block. The limiting block can be inserted into the limiting groove along the second through groove. The longitudinal section of the limiting block is a regular hexagonal design. The second slide groove is arranged in a ring array on the side wall of the connecting rod. The second slide groove contains a second slider. A rotating ring is fixed on the side of the second slider that is far apart from each other. The outer wall of the rotating ring is rotatably connected to the inner wall of the second groove. A second spring is sleeved on the side wall of the connecting rod located between the fourth electromagnet and the rotating ring.

[0014] Furthermore, the drive unit includes: A gear ring is fixedly sleeved on the outer wall of the rotating ring on the side away from the fourth electromagnet. A second servo motor is fixedly mounted on the outer wall of the threaded tube. The output shaft of the second servo motor is equipped with a transmission mechanism so that the second servo motor can drive the gear ring to rotate through the transmission mechanism. The first connecting mechanism is the same as the second connecting mechanism except for the gear ring, the second servo motor and the transmission mechanism.

[0015] The beneficial effects of the present invention are as follows: The present invention, through the cooperation of the first connecting mechanism and the storage mechanism, enables the jujube kernels in multiple storage mechanisms to be turned over without opening the box, so that the jujube kernels in the lower layer can be turned over to the upper layer, thereby facilitating even contact with oxygen in the box and facilitating the discharge of carbon dioxide generated during fermentation, so as to avoid damage to the jujube kernels caused by uneven local fermentation, thereby avoiding affecting subsequent production.

[0016] This invention uses a storage mechanism and a limiting mechanism to compress the jujube kernels inside the first and second shells during the flipping process of the storage mechanism. This prevents the jujube kernels from sliding to one side of the first and second shells due to gravity during the flipping process, thereby preventing the jujube kernels from accumulating on one side of the first and second shells after flipping and thus avoiding affecting subsequent fermentation.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. All directional indicators (such as up, down, left, right, front, back, etc.) in 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 accompanying drawings). If the specific posture changes, the directional indicator will also change accordingly.

[0020] Example 1, please refer to Figure 1 , Figure 2 and Figure 12 An apparatus for preparing astringent-removing jujube seed powder using fermentation includes a box body 1 and a frame 10 fixedly installed at the opening of the box body 1. A box door 2 is hinged to the side of the frame 10 away from the box body 1. The apparatus also includes: Storage mechanisms 3 are arranged at intervals inside the box 1 for storing jujube kernels for fermentation. The top of the uppermost storage mechanism 3 has reserved space for each storage mechanism 3 to rotate, allowing it to move vertically and rotate. A first mounting frame 11 and a second mounting frame 4 are fixed to both sides of the outer wall of the frame 10. A first lifting mechanism 9 and a second lifting mechanism 5 are respectively installed inside the first mounting frame 11 and the second mounting frame 4. The lifting ends of the first lifting mechanism 9 and the second lifting mechanism 5 are respectively provided with a first connecting mechanism 7 and a second connecting mechanism 6. The storage mechanism 3 includes: A ring body 33 is disposed inside the housing 1. A first housing 31 and a second housing 34 are slidably disposed on the inner wall of the ring body 33 so that the first housing 31 and the second housing 34 can move along the axial direction of the ring body 33. A rubber ring 35 is fixedly disposed on the side of the first housing 31 and the second housing 34 that are close to each other. Limiting mechanisms 8 are disposed on both sides of the ring body 33 for connecting with the first connecting mechanism 7 and the second connecting mechanism 6. A driving device is disposed on the first connecting mechanism 7 and the second connecting mechanism 6. When the first connecting mechanism 7 and the second connecting mechanism 6 are connected to the corresponding limiting mechanism 8, the driving device can drive the corresponding limiting mechanism 8 to rotate.

[0021] In practice, the box door 2 is opened and the sealing plate 32 is opened. The jujube kernels and the inoculum to be fermented are mixed and placed in the space formed by the first shell 31, the second shell 34 and the rubber ring 35. After placement, the sealing plate 32 is closed and the box door 2 is closed so that the jujube kernels and the inoculum can ferment in the box 1.

[0022] During fermentation, the limiting blocks 75 of the first connecting mechanism 7 and the second connecting mechanism 6 are inserted into the limiting seats 82 of the limiting mechanisms 8 on both sides of the uppermost storage mechanism 3. Then, the first lifting mechanism 9 and the second lifting mechanism 5 drive the uppermost storage mechanism 3 upwards, during which the uppermost insertion rod 14 disengages from its lower slot 84. As it continues to move upwards, both the top and bottom of the uppermost storage mechanism 3 have space to flip, allowing the first connecting mechanism 7 to flip the uppermost storage mechanism 3. This flips the jujube kernels from the lower layer of the storage mechanism 3 to the upper layer, allowing the jujube kernels that have been piled up at the bottom of the second shell 34 and in contact with the inner wall of the bottom of the second shell 34 for a long time to be flipped to the top. This facilitates even contact with oxygen and other substances inside the chamber 1, preventing uneven fermentation and damage to the jujube kernels, thus ensuring the stability of the fermentation process.

[0023] After the uppermost storage mechanism 3 is flipped, the first lifting mechanism 9 and the second lifting mechanism 5 continue to move the uppermost storage mechanism 3 upward. After moving to the designated height, the limiting block 75 of the first connecting mechanism 7 disengages from the limiting groove 85. Under the action of the first lifting mechanism 9, the first connecting mechanism 7 moves to the next layer of storage mechanism 3 and inserts into the limiting grooves 85 of the limiting mechanisms 8 on both sides of the next layer of storage mechanism 3, thereby driving the next layer of storage mechanism 3 to move upward. During this process, the second connecting mechanism 6 remains connected to the limiting grooves 85 on both sides of the uppermost storage mechanism 3, thus maintaining the uppermost storage mechanism 3 at the designated height. After the next layer of storage mechanism 3 is moved up to a specified height and then flipped, it continues to move up and the slot 84 is fitted onto the side wall of the insertion rod 14, so that the upper and lower layers of storage mechanism 3 are connected as a whole. At this time, the second connecting mechanism 6 is released from its limit on the uppermost storage mechanism 3, and the next layer of storage mechanism 3 connected by the first connecting mechanism 7 is limited, so that the first connecting mechanism 7 can move down again and drive the next layer of storage mechanism 3 to move up. The above operation is repeated, so that multiple storage mechanisms 3 can be flipped, which facilitates full contact between the jujube kernels in multiple storage mechanisms 3 and oxygen, reduces the probability of uneven local fermentation, and improves the fermentation effect.

[0024] After all the storage mechanisms 3 are flipped over, the first connecting mechanism 7 and the second connecting mechanism 6 work together to move the multiple storage mechanisms 3 downwards so that the bottom of the lowest storage mechanism 3 is supported by the bottom inner wall of the box 1. This facilitates subsequent continuous fermentation and eliminates the need for the first connecting mechanism 7 and the second connecting mechanism 6 to always support the multiple storage mechanisms 3, thereby improving the stability of the device.

[0025] During the flipping process of the storage mechanism 3, the first shell 31 and the second shell 34 of the storage mechanism 3 are brought closer to each other, thereby squeezing the jujube kernels inside the first shell 31 and the second shell 34. This prevents the jujube kernels from sliding to one side of the first shell 31 and the second shell 34 due to gravity during the flipping process, thus preventing the jujube kernels from accumulating on one side of the first shell 31 and the second shell 34 after flipping, and avoiding affecting subsequent fermentation.

[0026] Before fermenting the jujube kernels in the first shell 31, the jujube kernels and the inoculum need to be mixed evenly and placed together in the space formed by the first shell 31, the second shell 34 and the rubber ring 35 to facilitate subsequent fermentation.

[0027] Please see Figures 12-16 The storage facility 3 also includes: An annular groove 393 is formed at the middle of the inner wall and the middle of the outer wall of the rubber ring 35 so that the rubber ring 35 can be bent along the annular groove 393 after being compressed. The sealing plate 32 is detachably mounted on the top of the first housing 31, and there are two of them, with the two sealing plates 32 located at opposite corners of the first housing 31; Mounting rod 38 is slidably disposed at the center of the first housing 31 and the second housing 34, and cover 37 is fixedly fitted on both ends of mounting rod 38.

[0028] Storage mechanism 3 also includes: A first electromagnet 39 is fixedly disposed on the inner wall of the cover 37. A second electromagnet 392 is sleeved on the inner wall of the cover 37. A sleeve 391 is fixedly disposed on the side of the second electromagnet 392 away from the first electromagnet 39. The end of the sleeve 391 away from the second electromagnet 392 is fixedly connected to the side of the first housing 31 and the second housing 34 away from each other. A first spring is sleeved on the outer wall of the sleeve 391. The reinforcing plate 36 is fixedly disposed on the side of the second electromagnet 392 away from the first electromagnet 39 and extends to the outside of the cover 37. The side wall of the cover 37 is provided with a first through groove for vertical movement of the reinforcing plate 36. One end of the reinforcing plate 36 located outside the cover 37 is fixedly connected to the side of the first housing 31 and the second housing 34 that are away from each other, so as to connect to the second electromagnet 392 from a position close to the outer wall of the first housing 31 and the second housing 34.

[0029] The first housing 31 and the second housing 34 are arranged symmetrically with respect to the center point of the ring 33. The side walls and bottom of the first housing 31 and the second housing 34 are provided with spaced first guide holes, and the side walls of the rubber ring 35 are provided with spaced second guide holes. The first electromagnet 39 and the second electromagnet 392 are both ring-shaped, and the first electromagnet 39, the second electromagnet 392 and the sleeve 391 are all sleeved on the side wall of the mounting rod 38.

[0030] In specific implementation, before the storage mechanism 3 is flipped, the first electromagnet 39 and the second electromagnet 392 are energized, causing a repulsive force between them. This repulsive force pushes the second electromagnet 392 and the sleeve 391 to move. As a result, the first electromagnet 39 and the second electromagnet 392, which are on opposite sides of the first shell 31 and the second shell 34, move the first shell 31 and the second shell 34 closer together. This causes the first shell 31 and the second shell 34 to compress the rubber ring 35, thereby folding the rubber ring 35. This allows the first shell 31 and the second shell 34 to compress the jujube kernels inside, thus limiting the jujube kernels inside the first shell 31 and the second shell 34 from sliding to one side during the flipping process. This prevents excessive accumulation of jujube kernels on one side of the first shell 31 and the second shell 34 after the flipping is completed, facilitating subsequent fermentation and use. It also does not affect the ability to flip the lower layer of jujube kernels to the upper layer after the flipping, ensuring even fermentation and use.

[0031] By providing an annular groove 393, when the first shell 31 and the second shell 34 compress the rubber ring 35, the rubber ring 35 folds along the annular groove 393, thus facilitating the compression of the jujube kernels by bringing the first shell 31 and the second shell 34 closer together. Furthermore, the rubber ring 35 creates a space between the first shell 31 and the second shell 34 that can hold the jujube kernels. First and second guide holes are provided on the side walls of the first shell 31, the second shell 34, and the rubber ring 35 to facilitate contact with oxygen inside the chamber 1, thus facilitating actual fermentation and allowing carbon dioxide generated during fermentation to be released into the chamber 1.

[0032] The first housing 31 and the second housing 34 are slidably connected to the ring 33, allowing the first housing 31 and the second housing 34 to move vertically while restricting their rotation. By providing a first electromagnet 39 and a second electromagnet 392 on opposite sides of the first housing 31 and the second housing 34, when the first electromagnet 39 and the second electromagnet 392 are pushed closer together by repulsive force, the first electromagnet 39 and the mounting rod 38 remain stable under the opposing force, thus facilitating the pushing of the first housing 31 and the second housing 34 closer together.

[0033] The reinforcing plate 36 allows the outer edges of the first shell 31 and the second shell 34 to be subjected to force and move closer to each other, thereby improving the uniformity of the compression of the jujube kernels and improving the effect of limiting the slippage of the jujube kernels during the turning process. This facilitates the uniform arrangement of the jujube kernels after turning, making it easier for them to be used in subsequent fermentation.

[0034] After the flipping is completed, the first electromagnet 39 and the second electromagnet 392 are de-energized. Under the action of the first spring and gravity, the jujube kernel moves away from the first shell 31 or the second shell 34 below it, so that the upper first shell 31 or the second shell 34 moves away from the surface of the flipped jujube kernel, so that the jujube kernel that was originally in contact with the first shell 31 or the second shell 34 can come into contact with oxygen in the box 1, which is convenient for actual fermentation.

[0035] Please see Figure 1 , Figure 2 and Figure 14 The limiting mechanism 8 includes: The limiting seat 82 has a rotating component 83 fitted inside its center. One end of the rotating component 83 inside the limiting seat 82 is spherical, and the other end outside the limiting seat 82 is cylindrical and is fixedly connected to the outer wall of the ring 33. The side wall of the frame 10 has a movable through groove 12. The movable through grooves 12 on both sides of the frame 10 are respectively connected to the interior of the first mounting frame 11 and the second mounting frame 4. The inner walls on both sides of the movable through groove 12 have a first sliding groove 13. The interior of the first sliding groove 13 contains a first slider. The side of the first slider that is close to each other is fixedly connected to the side wall of the limiting seat 82. The side of the first slider that is far away from each other is fitted with a ball bearing 81.

[0036] Please see Figures 4-9 The limiting mechanism 8 also includes: The slot 84 is formed on one side wall of the rotating member 83 located inside the limiting seat 82 and extends to the top of the limiting seat 82. The bottom of the upper limiting seat 82 is fixedly provided with a plug rod 14. The plug rod 14 can be inserted into the slot 84 on the lower limiting seat 82 and the rotating member 83. A limiting groove 85 is formed on one side wall of the rotating member 83 located inside the limiting seat 82. The limiting groove 85 is located on the side of the rotating member 83 away from the ring body 33. A second through groove is formed on the side of the limiting seat 82 away from the ring body 33. The inner diameter of the second through groove is larger than the inner diameter of the limiting groove 85.

[0037] In practical implementation, the first slide groove 13 limits the movement of the limiting seat 82 within the moving through groove 12, thereby ensuring the stable lifting and lowering of the ring 33. This ensures that the two sides of the ring 33 remain horizontal when it is subsequently lifted and lowered. The ball bearings 81 reduce the friction between the first slider and the first slide groove 13, thereby improving the smoothness of vertical movement when the ring 33 is moved vertically by either the first connecting mechanism 7 or the second connecting mechanism.

[0038] By connecting the ring body 33 with the rotating component 83, the first shell 31 and the second shell 34 can approach each other and squeeze the jujube kernels within the ring body 33 without affecting the rotation of the ring body 33 and the first shell 31, thus facilitating the rotation of the jujube kernels.

[0039] Inserting the rod 14 into the slot 84 limits the rotation of the upper and lower rotating parts 83. After the first connecting mechanism 7 and the second connecting mechanism 6 are separated from the limiting mechanism 8, the ring 33 will not rotate along the central axis of the rotating part 83, ensuring the stability of the multiple storage mechanisms 3. After the rod 14 is separated from the slot 84, it is easy to drive the ring 33 to flip, which is convenient for subsequent fermentation.

[0040] Please see Figure 3The first lifting mechanism 9 and the second lifting mechanism 5 are identical, used to drive the first connecting mechanism 7 and the second connecting mechanism 6 to rise and fall respectively. The first lifting mechanism 9 includes: A threaded rod 91 is rotatably mounted on the inner wall of the first mounting frame 11. A threaded tube 92 is threadedly connected to the side wall of the threaded rod 91. The outer wall of the threaded tube 92 away from the frame 10 is slidably connected to the inner wall of the first mounting frame 11. A first servo motor for driving the threaded rod 91 to rotate is fixedly mounted on the top of the first mounting frame 11.

[0041] In practice, the first servo motor drives the threaded rod 91 to rotate, and the threaded rod 91 drives the threaded tube 92 to move vertically under the limit, thereby driving the first connecting mechanism 7 to rise and fall, so as to drive the storage mechanism 3 to rise and fall.

[0042] The first lifting mechanism 9 and the second lifting mechanism 5 drive the first connecting mechanism 7 and the second connecting mechanism 6 to rise and fall respectively, thereby facilitating the movement of the upper and lower storage mechanisms 3 through the first connecting mechanism 7 and the second connecting mechanism 6, which is convenient for actual operation.

[0043] Please see Figures 9-11 The first connecting mechanism 7 includes: The connecting seat 71 is fixedly disposed on the outer wall of the threaded tube 92 near the frame 10. A first groove 73 is provided on the side of the connecting seat 71 away from the threaded tube 92. A second groove 792 is provided on the inner wall of the first groove 73. The inner diameter of the second groove 792 is larger than the inner diameter of the first groove 73.

[0044] The first connecting mechanism 7 also includes: The third electromagnet 77 is fixedly disposed on the inner wall of the second groove 792. The inner wall of the second groove 792 is fitted with a fourth electromagnet 78. Both the fourth electromagnet 78 and the third electromagnet 77 are annular. The inner wall of the fourth electromagnet 78 is fixedly fitted with a connecting rod 74. One end of the connecting rod 74 located outside the connecting seat 71 is fixedly fitted with a limiting block 75. The limiting block 75 can be inserted into the limiting groove 85 along the second through groove. The longitudinal section of the limiting block 75 is a regular hexagonal design. The second slide groove 76 is arranged in a ring array on the side wall of the connecting rod 74. The second slider is placed inside the second slide groove 76. A rotating ring 79 is fixed on the side of the second slider that is far away from each other. The outer wall of the rotating ring 79 is rotatably connected to the inner wall of the second groove 792. A second spring is sleeved on the side wall of the connecting rod 74 located between the fourth electromagnet 78 and the rotating ring 79.

[0045] The drive unit includes: The gear ring 791 is fixedly sleeved on the outer wall of the rotating ring 79 away from the fourth electromagnet 78. The outer wall of the threaded tube 92 is fixedly equipped with a second servo motor. The output shaft of the second servo motor is equipped with a transmission mechanism 72 so that the second servo motor can drive the gear ring 791 to rotate through the transmission mechanism 72. The first connecting mechanism 7 is the same as the second connecting mechanism 6 except for the gear ring 791, the second servo motor and the transmission mechanism 72.

[0046] In practical implementation, when it is necessary to lift and rotate the storage mechanism 3, a repulsive force is first generated between the third electromagnet 77 and the fourth electromagnet 78. The repulsive force drives the fourth electromagnet 78 to move, thereby driving the connecting rod 74 and the limiting block 75 to move away from the limiting seat 82, so that the limiting block 75 can move to the outside of the limiting seat 82. After the first connecting mechanism 7 moves to the specified height, the power to the third electromagnet 77 and the fourth electromagnet 78 is cut off. Under the action of the second spring, the fourth electromagnet 78, the connecting rod 74 and the limiting block 75 are inserted into the limiting groove 85 along the second through groove, thereby connecting the first connecting mechanism 7 with the storage mechanism 3, so that under the action of the first lifting mechanism 9, the corresponding storage mechanism 3 can move vertically.

[0047] When the storage mechanism 3 is moved to the specified height, the gear ring 791 is driven to rotate by the second servo motor and the transmission mechanism 72, which in turn drives the connecting rod 74, the limit block 75 and the rotating ring 79 to rotate, thereby driving the ring body 33 to rotate, thus turning the jujube kernel over.

[0048] The rotating ring 79 is slidably connected to the connecting rod 74, and the rotating ring 79 is rotatably connected to the connecting seat 71, so that the movement of the connecting rod 74 does not affect the rotation of the connecting rod 74 driven by the gear ring 791, which facilitates the insertion of the limiting block 75 into the limiting groove 85 and drives the ring body 33 to flip for use.

[0049] The ring 33 can be limited by the engagement of the limiting block 75 and the limiting groove 85, thus restricting its rotation. After the limiting block 75 disengages from the limiting groove 85, the ring 33 is restricted from flipping by the cooperation of the insert rod 14 and the slot 84, so that the ring 33 is always in a horizontal position after flipping, which facilitates the next flipping and use.

[0050] The transmission mechanism 72 includes multiple meshing gears, one of which meshes with the outer wall of the gear ring 791, and the other gear is fixedly connected to the output shaft of the second servo motor, thereby causing the second servo motor to drive the gear ring 791 to rotate. Through the transmission mechanism 72 and the gear ring 791, the connecting rod 74 is driven to rotate without affecting the movement of the connecting rod 74, which is convenient for actual operation.

[0051] All servo motors and electromagnets in this invention are connected to an external power supply and controller via wires for practical control and use. This is existing technology and will not be described in detail here.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
