Description

Technical Field

[0001] This invention relates to the field of fruit embryo spreading technology, and in particular to a flexible fruit embryo spreading device for dried fruit production. Background Technology

[0002] In the dried fruit production process, spreading the fruit embryos is one of the key steps. The core requirement is to spread the fruit embryos evenly and gently on the conveyor mechanism to facilitate subsequent processing such as drying and seasoning. Currently, most spreading devices used in dried fruit production employ rigid conveying or direct feeding methods, which have several drawbacks: Firstly, the supporting structure of traditional spreading devices is mostly a fixed rigid structure. During the conveying and feeding process, the fruit embryos are prone to hard collisions with the supporting structure, resulting in damage and breakage of the fruit embryos, which affects the appearance and quality of the dried fruit products. Secondly, during the spreading process, the fruit embryos have a large height difference when falling, which makes them prone to piling up and clumping, making it difficult to spread evenly. This affects the subsequent drying efficiency and uniformity, resulting in inconsistent moisture content in the dried fruit products. Third, some adjustable material spreading devices have complex adjustment structures, are inconvenient to operate, and cannot provide flexible protection during the fruit embryo transportation process, still posing a risk of fruit embryo damage. Summary of the Invention

[0003] The purpose of this invention is to solve the defects of existing fruit drying production spreading devices, such as easy damage to fruit embryos, uneven spreading, lack of impurity screening function, and complex structure, and to propose a flexible fruit embryo spreading device for dried fruit production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A flexible fruit embryo spreading device for dried fruit production includes a belt conveyor, which is disposed between a drive wheel and a driven wheel and is driven to rotate by the drive wheel. The belt conveyor is inclined and has multiple bearing parts equidistantly arranged on it. Each bearing part includes a positioning seat and a moving seat. The positioning seat includes two end caps and a fixed arc-shaped seat disposed between the end caps; The movable seat includes a disc-shaped rotating disk and a movable arc-shaped seat disposed between the rotating disks. The rotating disk rotates on the opposite surface of the end cover, and the outer wall of the movable arc-shaped seat rotates on the inner wall of the fixed arc-shaped seat. As the carrying unit moves upward along the belt conveyor, the movable arc-shaped seat first adheres to the inner wall of the fixed arc-shaped seat. When it passes the dried fruit hopper, the dried fruit falls into the inner wall of the movable arc-shaped seat, thus loading the carrying unit. As the carrying unit continues to move upward along the belt conveyor, the movable arc-shaped seat rotates outward until a closed-loop ring structure is formed between the movable arc-shaped seat and the fixed arc-shaped seat, storing the dried fruit on the inner wall of the ring structure. This causes the vertical position of the fixed arc-shaped seat and the movable arc-shaped seat to change as the carrying unit moves downward along the belt conveyor, and the dried fruit falls onto the inner wall of the movable arc-shaped seat under the action of gravity. When the carrying unit moves downward along the belt conveyor to the bottom, the movable arc-shaped seat slowly moves towards overlapping with the fixed arc-shaped seat, causing the dried fruit to fall from the opening between the movable arc-shaped seat and the fixed arc-shaped seat onto the laying conveyor belt directly below the belt conveyor with a lower height difference.

[0005] Furthermore, the outer wall of the belt conveyor is provided with an outer shell, and the dried fruit hopper is fixed on the outer shell. The outer shell is provided with an installation groove corresponding to the belt conveyor. The outer shell is used to protect the belt conveyor and the load-bearing part to prevent external impurities from entering, and at the same time provides an installation foundation for the dried fruit hopper and subsequent transmission structure.

[0006] Furthermore, a rotating shaft is fixed to the outer wall of the rotating disk. The outer end of the rotating shaft passes through and rotates on the end cover. A gear is provided at the outer end of the rotating shaft. A rack is provided on the inner wall of the mounting groove and meshes with the gear. The rack is located at the top of the belt conveyor. As the belt conveyor rotates, the gear and rack mesh, causing the moving arc-shaped seat to rotate relative to the fixed arc-shaped seat until they form a closed loop. A locking element is provided between the gear and the end cover. When the moving arc-shaped seat rotates relative to the fixed arc-shaped seat until they form a closed loop, the locking element locks the state between the gear and the end cover, preventing the gear and the end cover from rotating relative to each other, ensuring the stability of the loop structure, and preventing the dried fruit from falling off during the conveying process.

[0007] Furthermore, the locking component includes a locking pin, and the end cap is provided with a locking hole corresponding to the locking pin. When the locking pin is inserted into the locking hole, it prevents the gear and the end cap from rotating relative to each other. Under the action of the return spring, the locking pin returns to its initial outward protrusion state. The structure is simple, the locking is reliable, and it can achieve automatic reset without manual operation.

[0008] Furthermore, the inner wall of the mounting groove is provided with a sliding groove corresponding to the sliding of the locking pin. The sliding groove is located directly below the rack and the length of the sliding groove is the same as that of the rack. The top of the sliding groove is provided with an inclined guide groove. When the locking pin slides along the sliding groove, the locking pin disengages from the locking hole, causing the rack and the gear to engage, thus realizing the rotation of the moving seat. When the locking pin slides along the inclined guide groove, the locking pin moves into the locking hole, locking the gear and the end cover, preventing the gear from rotating. Through the cooperation of the sliding groove and the inclined guide groove, the locking pin can be automatically unlocked and locked, adapting to the movement trajectory of the bearing part and ensuring the continuous and stable operation of the device.

[0009] Furthermore, the lower inner wall of the mounting groove is provided with a release groove corresponding to the locking pin. When the locking pin slides in the release groove, the locking pin disengages from the locking hole, providing an unlocking condition for the reset rotation of the moving seat and ensuring that the dried fruit can be smoothly discharged.

[0010] In one embodiment of the present invention, the outer wall of the rotating shaft is connected to the end cover by a torsion spring. When the locking pin slides in the release groove, the locking pin disengages from the locking hole. Under the action of the torsion spring, the moving arc seat slides along the fixed arc seat toward the direction of the belt conveyor, so that the dried fruit falls from the opening of the fixed arc seat and the moving arc seat. The opening is close to the direction of the belt conveyor. The moving seat is automatically reset by the torsion spring. The structure is simple, requires no additional power drive, and reduces the energy consumption of the equipment.

[0011] In another embodiment of the present invention, a rack two is provided in the mounting groove. The length of the rack two is the same as the length of the disengagement chute and it is located above the disengagement chute. When the locking pin slides in the disengagement chute, the locking pin disengages from the locking hole, and the rack two meshes with the gear, causing the moving arc-shaped seat to slide along the fixed arc-shaped seat away from the belt conveyor. This allows the dried fruit to fall from the openings of the fixed arc-shaped seat and the moving arc-shaped seat, which are away from the belt conveyor. Through the meshing transmission of the rack two and the gear, the moving seat is accurately reset, adapting to the feeding requirements of different sized fruit embryos and improving the versatility of the device.

[0012] Furthermore, the fixed arc-shaped seat is provided with multiple discharge holes, which are used to screen small impurities or small dried fruits. When the dried fruits are located within the closed-loop annular structure, the small impurities or small dried fruits fall from the discharge holes. The belt conveyor is provided with guide holes, which are located between the two bearing parts and close to the top of the fixed arc-shaped seat. After the small impurities or small dried fruits fall from the discharge holes, they are guided by the outer wall of the moving arc-shaped seat at the top of the closed-loop annular structure and fall into the guide holes. They are then guided to the outside by the feeding guide seat provided inside the belt conveyor, realizing the synchronous screening of fruit embryos and small impurities. This eliminates the need for additional screening processes, simplifies the production process, and improves the quality of the finished dried fruit.

[0013] Furthermore, an elastic sealing part is provided inside the guide hole. When the moving arc-shaped seat rotates outward relative to the fixed arc-shaped seat, it abuts against the elastic sealing part, causing the guide hole to open, thereby facilitating the guidance of small impurities or small dried fruits from the guide hole into the feeding guide seat. When the moving arc-shaped seat returns to its original position, the elastic sealing part automatically closes, preventing external impurities from entering the belt conveyor and avoiding fruit embryos from falling into the guide hole during the conveying process, thus ensuring the normal operation of the device.

[0014] The beneficial effects of this invention are as follows: 1. Achieving flexible bearing and conveying of fruit embryos: Through the cooperation of the positioning seat and the moving seat, the moving arc-shaped seat can rotate flexibly relative to the fixed arc-shaped seat. During the feeding, conveying and unloading process, the fruit embryos are always in flexible contact with the arc-shaped inner wall, avoiding hard collisions, effectively reducing the damage and breakage of the fruit embryos, and significantly improving the appearance and quality of the dried fruit products.

[0015] 2. High uniformity of material distribution: When the bearing part moves downward to the bottom, the moving arc seat slowly resets, and the dried fruit falls onto the laying conveyor belt with a low height difference, avoiding the accumulation and clumping of dried fruit during the fall, achieving uniform distribution of fruit embryos, ensuring the uniformity of subsequent drying processes, and improving the consistency of moisture content of the finished dried fruit products.

[0016] 3. Simultaneous impurity screening: The feeding holes on the fixed arc-shaped seat can screen out small impurities or small dried fruits in the fruit embryos. Combined with the guide holes and feeding guide seats, impurities can be separated simultaneously without the need for additional screening processes, simplifying the production process, reducing production costs, and improving the purity of the finished dried fruit.

[0017] 4. Reasonable structure and stable operation: The automatic rotation and locking of the moving seat is achieved through the cooperation of gears, racks and pinions, which is compatible with the inclined motion trajectory of the belt conveyor. No manual intervention is required, ensuring continuous and stable operation of the device. The locking component adopts a combination of locking pin and return spring, which is simple in structure, reliable in locking, and can automatically reset, reducing equipment maintenance costs.

[0018] 5. High versatility and adaptability: It provides two moving seat reset methods, which can be flexibly selected according to the size of the fruit embryo and production needs, and adapt to the production needs of different types of dried fruits; the setting of the elastic sealing part not only ensures that impurities are discharged smoothly, but also prevents external impurities from entering, ensuring that the device is adaptable to different production environments.

[0021] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Example 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 13 As shown, this embodiment provides a flexible fruit embryo spreading device for dried fruit production, including a strip conveyor belt 1 set above the spreading conveyor belt, and the strip conveyor belt 1 is set at an inclination angle of 30-45° to facilitate the feeding and unloading of the subsequent bearing part 20; the bottom of the strip conveyor belt 1 is close to the spreading conveyor belt.

[0024] In some embodiments, the belt conveyor 1 is a conveyor belt structure such as polyurethane conveyor belt, silicone rubber (silicone) conveyor belt, polytetrafluoroethylene (PTFE / Teflon) conveyor belt, and natural rubber / nitrile rubber (NBR) conveyor belt in the prior art.

[0025] The belt conveyor 1 is positioned between the driving wheel and the driven wheel (not shown in the figure). The driving wheel is driven by a drive motor, which in turn drives the belt conveyor 1 to rotate at a constant speed. The driven wheel cooperates with the driving wheel to provide support for the stable rotation of the belt conveyor 1.

[0026] In addition, this embodiment also improves the existing technology of the baffles on the belt conveyor 1 (whose function is to stack dried fruit on the baffles as the belt conveyor 1 rotates, thereby realizing the feeding, movement and dropping of dried fruit onto the laying conveyor belt). After the improvement, the baffles are modified into bearing parts 20, wherein there are multiple bearing parts 20, and they are equally spaced on the belt conveyor 1. Preferably, the distance between two adjacent bearing parts 20 is 15-20cm to ensure that the dried fruit can be laid evenly and avoid accumulation.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 and Figure 11In this embodiment, the supporting part 20 includes a positioning seat 20 and a moving seat 21.

[0028] The positioning seat 20 is fixedly connected to the outer wall of the belt conveyor 1 and moves synchronously with the belt conveyor 1. In some embodiments, the positioning seat 20 includes two end caps 200 and a fixed arc-shaped seat 201 disposed between the two end caps 200. The end caps 200 are disc-shaped, and the fixed arc-shaped seat 201 has a semi-circular arc structure with a smooth inner wall to reduce friction with the fruit embryo and avoid damage to the fruit embryo.

[0029] In addition, the movable seat 21 includes a disc-shaped rotating disk 210 and a movable arc-shaped seat 211 disposed between the two rotating disks 210. The diameter of the rotating disk 210 is the same as the inner diameter of the fixed arc-shaped seat 201. The rotating disk 210 is rotatably connected to the opposite surface of the end cap 200 through a bearing. The movable arc-shaped seat 211 is also a semi-circular arc structure. Its outer wall is adapted to the inner wall of the fixed arc-shaped seat 201, and the outer wall of the movable arc-shaped seat 211 rotates and fits against the inner wall of the fixed arc-shaped seat 201. The inner wall of the movable arc-shaped seat 211 is provided with a flexible buffer layer to further improve the flexibility of the fruit embryo bearing.

[0030] To facilitate the placement of the belt conveyor 1, an outer shell 3 is provided on the outer wall of the belt conveyor 1. The outer shell 3 is made of stainless steel, which has the advantages of corrosion resistance and easy cleaning. A dried fruit hopper is provided on it, and the outlet of the dried fruit hopper is directly opposite the feeding area of ​​the belt conveyor 1, so that the dried fruit can fall accurately into the bearing part 20. In some embodiments, the conveying and cooperation method between the dried fruit hopper and the belt conveyor 1 is the prior art. The cooperation relationship between the feeding hopper and the annular belt can be referred to in the "A Flexible Spreading Device for Dried Fruit Embryos" application No. "202210672090.3", which will not be described in detail here. In addition, an installation groove adapted to the belt conveyor 1 is opened on the outer shell 3. The width of the installation groove is the same as the width of the belt conveyor 1, providing installation space for the subsequent transmission structure and locking structure.

[0031] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 10 Two rotating shafts 212 are fixed on the outer wall of the rotating disk 210. The rotating shafts 212 are coaxially arranged with the rotating disk 210. The outer end of the rotating shaft 212 passes through the end cover 200 and is rotatably connected to the end cover 200 through a bearing. At the same time, a gear 213 is fixed on the outer end of the rotating shaft 212. The gear 213 is coaxially arranged with the rotating shaft 212.

[0032] Reference Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 Based on the setting of gear 213, in order to drive the rotation of gear 213, a rack 214 that meshes with gear 213 is fixed on the inner wall of the mounting groove. The rack 214 is set at the top position of the belt conveyor 1, and the length of rack 214 is less than the horizontal projection length of the top of the belt conveyor 1. When the belt conveyor 1 rotates, the bearing part 20 moves upward with the belt conveyor 1. Gear 213 meshes with rack 214 to drive the rotating shaft 212 and rotating disk 210 to rotate, which in turn drives the moving arc seat 211 to rotate outward relative to the fixed arc seat 201 until the moving arc seat 211 and the fixed arc seat 201 form a closed ring structure, which encloses the dried fruit in the inner wall of the ring structure to prevent the dried fruit from falling during the conveying process.

[0033] In some other embodiments, to ensure the stability of the closed-loop annular structure after the gear 213 and rack 214 disengage, a locking element 215 is provided between the gear 213 and the end cover 200. The locking element 215 includes a locking pin, and the end cover 200 has a locking hole (not shown in the figure) adapted to the locking pin. The locking pin slides through the radial through hole of the gear 213, and one end of the locking pin is connected to a return spring. The other end of the return spring is fixedly connected to the inner wall of the gear 213. Under the elastic force of the return spring, the locking pin returns to its initial outward protruding state. Furthermore, the inner wall of the mounting groove has a sliding groove adapted to the locking pin. The sliding groove is located directly below the rack 214, and the length of the sliding groove is the same as the length of the rack 214. The top of the sliding groove is provided with an inclined guide groove, which is smoothly connected to the sliding groove and is inclined towards the direction of the locking hole.

[0034] It should be added that: In another embodiment, the last tooth of the rack 214 is mounted on the end seat, and the end seat can move outward perpendicular to the rack 214 under the action of the elastic element; at the same time, the end seat is set in a slanted guide groove relative to the slanted guide groove. Based on the movement of the end seat, when the locking pin slides on the slanted guide groove, the locking pin moves into the locking hole, and the gear 213 drives the end seat to move outward, thereby realizing the disengagement of the gear 213 and the rack 214, and the locking pin is inserted into the locking hole, ensuring the stability of the closed-loop annular structure.

[0035] It should also be noted that: when the bearing part 20 moves upward along the belt conveyor 1, the locking pin slides along the sliding groove. At this time, the locking pin protrudes outward under the action of the return spring and disengages from the locking hole, allowing the gear 213 to rotate freely, ensuring normal meshing and transmission between the rack 214 and the gear 213, and realizing the rotation of the moving arc seat 211; when the moving arc seat 211 and the fixed arc seat 201 form a closed ring structure, the locking pin moves to the position of the inclined guide groove and slides along the inclined guide groove. The inclined guide groove generates an inward pushing force on the locking pin, overcoming the elastic force of the return spring, causing the locking pin to move into the locking hole and insert into the locking hole, locking the relative position of the gear 213 and the end cover 200, preventing the gear 213 and the end cover 200 from rotating relative to each other, and ensuring the stability of the ring structure.

[0036] Furthermore, refer to Figure 11 To facilitate the unloading of dried fruit within the closed-loop annular structure, a release groove is provided on the lower inner wall of the mounting groove relative to the sliding groove, which is adapted to the locking pin. The release groove is located at the bottom of the belt conveyor 1. When the bearing part 20 moves down along the belt conveyor 1 to the bottom, the locking pin moves to the release groove position under the action of the return spring. The inner wall of the release groove contacts the end of the locking pin, pushing the locking pin outward, so that the locking pin disengages from the locking hole, releasing the lock between the gear 213 and the end cover 200.

[0037] In this embodiment, the outer wall of the rotating shaft 212 is connected to the end cover 200 by a torsion spring. The torsion spring is sleeved on the rotating shaft 212, and one end of the torsion spring is fixedly connected to the end cover 200, and the other end is fixedly connected to the rotating shaft 212. When the locking pin slides in the release groove and disengages from the locking hole, the elastic force of the torsion spring drives the rotating shaft 212 to rotate in the opposite direction, thereby driving the rotating disk 210 and the moving arc seat 211 to rotate along the fixed arc seat 201 towards the direction of the belt conveyor 1, so that the moving arc seat 211 and the fixed arc seat 201 gradually overlap, forming an opening between them. The dried fruit falls from this opening onto the laying conveyor belt directly below the belt conveyor 1 with a low height difference, achieving uniform material spreading. The direction of the opening towards the belt conveyor 1 ensures that the falling trajectory of the dried fruit is accurate and avoids deviation.

[0038] In other embodiments, the fixed arc-shaped seat 201 is provided with a plurality of discharge holes 2010, which are evenly distributed on the arc surface of the fixed arc-shaped seat 201. The diameter of the discharge holes 2010 is 2-3mm, which are used to screen out small impurities or small dried fruit embryos that do not meet the production specifications in the dried fruit. The belt conveyor 1 is provided with guide holes 10, which are located between two adjacent bearing parts 20 and are close to the top of the fixed arc-shaped seat 201. The number of guide holes 10 is the same as the number of bearing parts 20 and they correspond one-to-one. The belt conveyor 1 is provided with a feeding guide seat 4 inside. The feeding guide seat 4 is funnel-shaped or has an inclined guide rail structure with an edge. Its upper opening is directly opposite the guide hole 10 and its lower end extends to the outside of the device, which facilitates the discharge of small impurities or small dried fruit.

[0039] Furthermore, when the dried fruit is stored within the closed-loop annular structure, small impurities or small dried fruits fall from the discharge hole 2010 on the fixed arc-shaped seat 201 under the influence of gravity. The falling impurities are guided by the outer wall of the moving arc-shaped seat 211 at the top of the closed-loop annular structure and then accurately fall into the guide hole 10. They are then guided to the outside of the device by the feeding guide seat 4, thus achieving synchronous screening of the fruit embryos and small impurities or small dried fruits. In addition, the guide hole 10 is equipped with an elastic sealing part, which is a sealing gasket made of rubber material. One end of the sealing gasket is hinged to the inner wall of the guide hole 10, and the other end is connected to the inner wall of the guide hole 10 through an elastic sheet. When the movable arc seat 211 rotates outward relative to the fixed arc seat 201, the end of the movable arc seat 211 abuts against the elastic sealing part, causing the elastic sealing part to open, and the guide hole 10 opens accordingly, making it easier for impurities to fall in. When the movable arc seat 211 is reset, the elastic sealing part automatically closes under the action of the elastic sheet, preventing external impurities from entering the belt conveyor 1 and preventing the fruit embryos from falling into the guide hole 10 during the conveying process.

[0040] The working process of this embodiment is as follows: 1. Feeding stage: The drive motor starts, drives the drive wheel to rotate, and then drives the belt conveyor 1 to rotate at a constant speed. The bearing part 20 moves upward with the belt conveyor 1. At this time, the moving arc seat 211 is attached to the inner wall of the fixed arc seat 201, and the locking pin slides along the sliding groove and disengages from the locking hole. When the bearing part 20 moves to below the discharge port of the dried fruit hopper, the dried fruit falls from the dried fruit hopper into the inner wall of the moving arc seat 211, completing the feeding of the bearing part 20.

[0041] 2. Conveying and Screening Stage: The bearing unit 20 continues to move upward along the belt conveyor 1. The gear 213 meshes with the rack 214, driving the moving arc seat 211 to rotate outward relative to the fixed arc seat 201 until the moving arc seat 211 and the fixed arc seat 201 form a closed ring structure. At this time, the locking pin moves to the position of the inclined guide groove, slides along the inclined guide groove and inserts into the locking hole, locking the relative position of the gear 213 and the end cover 200. The dried fruit is stored in the ring structure. Small impurities or small dried fruit fall from the discharge hole 2010 of the fixed arc seat 201, are guided by the outer wall of the moving arc seat 211 and fall into the guide hole 10, and then are discharged outside the device through the feeding guide seat 4, completing the impurity screening.

[0042] 3. Material spreading stage: The bearing part 20 continues to move along the belt conveyor 1, and after passing the top, it begins to move downward. At this time, the vertical position of the fixed arc seat 201 and the moving arc seat 211 changes, and the dried fruit falls onto the inner wall of the moving arc seat 211 under the action of gravity. When the bearing part 20 moves to the bottom of the belt conveyor 1, the locking pin moves to the position of disengaging from the chute and disengaging from the locking hole. Under the action of the torsion spring, the moving arc seat 211 rotates along the fixed arc seat 201 towards the belt conveyor 1, gradually overlapping with the fixed arc seat 201 to form an opening. The dried fruit falls from this opening onto the spreading conveyor belt directly below the belt conveyor 1 with a lower height difference, achieving uniform spreading. Then the bearing part 20 continues to move with the belt conveyor 1 and enters the next working cycle.

[0043] Example 2 differs from Example 1 in that the reset method of the moving seat 21 is different, while the rest of the structure is the same as in Example 1.

[0044] Specifically, refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13A rack 216 is fixed in the mounting groove. The length of rack 216 is the same as the length of the disengagement chute, and rack 216 is located above the disengagement chute. The tooth direction of rack 216 is opposite to that of rack 214. When the locking pin slides in the disengagement chute, the locking pin disengages from the locking hole. At this time, the bearing part 20 moves downward with the belt conveyor 1. The gear 213 meshes with rack 216, driving the rotating shaft 212 to rotate in the opposite direction. This, in turn, drives the rotating disk 210 and the moving arc seat 211 to rotate along the fixed arc seat 201 in a direction away from the belt conveyor 1, so that the moving arc seat 211 and the fixed arc seat 201 gradually overlap to form an opening. The dried fruit falls from this opening onto the laying conveyor belt with a low height difference, achieving uniform spreading. This opening is in a direction away from the belt conveyor 1, which is suitable for the dropping of larger fruit embryos.

[0045] In this embodiment, the precise resetting of the moving seat 21 is achieved through the meshing transmission of rack 216 and gear 213. The resetting speed can be adjusted by the rotation speed of the belt conveyor 1 to adapt to the material feeding requirements of different sized fruit embryos and improve the versatility of the device.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
