Description

Technical Field

[0001] The present invention relates to the technical field of fruit sorting and conveying, and in particular to macadamia nut conveying equipment with a sorting mechanism. Background Art

[0002] After harvesting, macadamia nuts need to be cleaned immediately to remove impurities such as branches and leaves. They are then transported to the processing center via conveyor belts or agricultural vehicles over short distances. At the processing plant, high-pressure water guns or drum washers are first used to thoroughly remove the mud and sand on the surface of the green peel. The nuts are then conveyed to the peeling process through a conveyor system. After the green peel is removed, the shelled nuts are washed again by water or vibrating screen channels and pre-dried. They then enter the sorting process, usually using multi-layer vibrating screens to classify by particle size. High-speed airflow is used to separate light impurities. Color sorters or manual assembly lines are then used to remove defects such as mold and damage. Qualified shelled nuts are dried and sent to temporary storage. Finally, they are packed into breathable woven bags or turnover boxes via conveyor belts or pneumatic conveying systems, ready for subsequent shelling processing or storage. The entire process focuses on preventing mechanical damage and mold. The existing conveying device has poor fruit screening effect when sorting fruits, and the fruits are easily damaged when vibrating. Therefore, we propose a macadamia nut conveying equipment with a sorting mechanism. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a macadamia nut conveying device with a sorting mechanism, comprising: A bottom plate, the top of which is fixedly connected to a bracket; A conveying mechanism, wherein the conveying mechanism is fixedly connected to the inner side surface of the bracket; Wherein, the conveying mechanism includes: A conveyor belt, the conveyor belt is arranged at the interval of the bracket and the conveyor belt is slidably connected to the inner side surface of the bracket; The conveyor belt surface is provided with sorting holes, and a plurality of the sorting holes are provided, and the plurality of sorting holes are evenly distributed on the conveyor belt surface; A drive assembly, the drive assembly being in driving connection with the inner side surface of the conveyor belt and the drive assembly being fixedly connected to the outer side surface of the bracket; A sorting and unloading component is provided at the interval of the conveyor belt, and the sorting and unloading component is arranged obliquely and fixedly connected to the top of the bottom plate; Put macadamia nuts onto the conveyor belt surface, start the drive assembly, and the output end of the drive assembly drives the conveyor belt to transmit, and the conveyor belt drives the macadamia nuts to transmit. Macadamia nuts smaller than the sorting holes pass through the conveyor belt and then enter the sorting and unloading assembly to finally be sorted. The sorting and unloading assembly is tilted inside the conveyor belt and can complete unloading and sorting under the weight of the macadamia nuts.

[0004] Further, a plurality of the conveyor belts are provided, and the plurality of conveyor belts are arranged in a stepped manner along the conveying direction. Sorting holes are formed in the surfaces of the plurality of conveyor belts, and the diameters of the sorting holes on the surfaces of the plurality of conveyor belts gradually decrease along the conveying direction. The sizes of the sorting holes on the plurality of conveyor belts gradually decrease, so that the smallest macadamia nuts first enter the sorting and blanking assembly, and then the macadamia nuts entering the sorting and blanking assembly gradually increase, realizing grading and screening. The plurality of conveyor belts arranged in a stepped manner have a vertical height between adjacent conveyor belts. When the macadamia nuts reach the next conveyor belt from the previous conveyor belt, due to the drop caused by the vertical height difference, the macadamia nuts are scattered and flipped to a certain extent during the falling process, so that the macadamia nuts are evenly spread on the surface of the conveyor belt, improving the screening effect.

[0005] Further, baffles are provided at intervals between adjacent conveyor belts. The side of the baffle close to the bottom plate is inclined towards the conveying direction. The two sides of the baffle are respectively slidably connected to the outer sides of the two conveyor belts. A central rod is rotatably connected to the center of the baffle through a torsion spring. The end of the central rod is fixedly connected to the inner side of the bracket. The setting of the baffle can fill the gap between adjacent conveyor belts, preventing irregularly shaped macadamia nuts from being bounced into the gap when hitting the conveyor belt and rebounding, ensuring that each macadamia nut passes through the screening of the sorting holes.

[0006] Further, convex strips are fixedly connected to the outer side surfaces of the conveyor belts. A plurality of the convex strips are provided, and the plurality of convex strips are evenly distributed on the surface of the conveyor belt, and the convex strips are arranged at intervals between adjacent sorting holes. As the conveyor belt conveys, the convex strips contact the baffle, causing the conveyor belt to move. Baffles are provided at intervals between the plurality of conveyor belts, and the two sides of the baffle are respectively slidably connected to the two conveyor belts, and the adjacent conveyor belts are arranged in a stepped manner, which means that a baffle is provided on each of the upper and lower sides at both ends of the conveyor belt. As the conveyor belt conveys, one end of the conveyor belt moves upward and the other end moves downward, resulting in the conveyor belt swinging, driving the macadamia nuts to jolt, achieving a better sorting effect. At the same time, the baffle is connected to the central rod through a torsion spring. When the force exerted by the convex strip on the baffle exceeds a predetermined threshold, the baffle rotates. After the convex strip passes through, the baffle resets under the elastic force of the torsion spring, thus not affecting the conveying of the conveyor belt. And when the convex strip presses the baffle, the initial elastic force of the torsion spring provides a certain resistance, making the baffle not rotate easily, thus ensuring that the conveyor belt swings with a sufficient amplitude, further improving the sorting efficiency. When the extrusion force of the convex strip exceeds the elastic force threshold preset by the torsion spring, the baffle rotates, and this process plays a buffering role, preventing the conveyor belt from overswinging or suffering mechanical damage due to continuous obstruction.

[0007] Furthermore, the driving assembly includes a driving box. A number of driving boxes are provided, and the number of driving boxes corresponds to that of the conveyor belt. The driving boxes are arranged outside the bracket. On one side of the driving box close to the conveyor belt, driving rods are symmetrically arranged, and the driving rods are fixedly connected to the output ends of the driving boxes. The two driving rods are respectively arranged at both ends of the conveyor belt, and the driving rods are in transmission connection with the inner side surface of the conveyor belt. When the driving box is started, the output end of the driving box drives the driving rods to rotate, thereby driving the conveyor belt to transport.

[0008] Furthermore, buffer rings are arranged on both sides of the conveyor belt. The inner side surface of the buffer ring is rotatably connected to the surface of the driving rod, and the outer side surface of the buffer ring is fixedly connected to the inner side surface of the bracket. Both ends of the buffer ring are recessed inward. The buffer ring is hollow and made of an elastic material. When the conveyor belt does not swing, the driving rod rotates inside the buffer ring. When the conveyor belt swings, the driving rod will be squeezed against the inner wall of the buffer ring due to the displacement of the conveyor belt. The recessed part of the buffer ring provides a larger buffer space through deformation, enabling the driving rod to have a more flexible range of motion during the swinging process, avoiding the conveyor belt from jamming or the driving rod from deforming due to hard collisions. The hollow elastic material absorbs the impact force generated by the swinging of the driving rod, converting mechanical energy into elastic potential energy, and effectively reducing the impact of the swing on the overall structure of the equipment.

[0009] Furthermore, a limit frame is fixedly connected to one side of the driving box close to the bracket. A ball head rod is slidably connected to the inner side surface of the limit frame, and the ball head rod is arranged in the middle of the limit frame. The side of the ball head rod away from the driving box is fixedly connected to the outer side surface of the bracket. When the conveyor belt swings, it drives the driving rod to swing, then drives the driving box to swing, and subsequently drives the limit frame to swing. The limit frame rotates outside the ball head rod. The ball hinge type limit structure formed by the limit frame and the ball head rod gives it a flexible degree of freedom of swinging while ensuring the stability of the driving box. When the conveyor belt swings under the action of the convex strips and the baffle, the spherical surface of the ball head rod forms a sliding constraint with multiple point contacts with the inner wall of the limit frame. It can not only adjust its posture following the swinging direction of the conveyor belt, but also restrict the conveyor belt through the boundary limit of the limit frame, allowing the conveyor belt to move up and down and deflect horizontally in three-dimensional space, causing the conveyor belt to have regular undulations, making the macadamia nuts jump under the dual action of gravity and inertia, and enabling the fruits to readjust their postures, greatly increasing the probability of them passing through the corresponding apertures.

[0010] Further, a spring is fixedly connected to the surface of the ball head rod. The springs are symmetrically arranged with the ball head rod as the center. The two ends of the springs away from the ball head rod are respectively fixedly connected to the upper and lower ends of the inner side surface of the limit frame. When the driving box deflects, the limit frame slides along the spherical surface of the ball head rod. During this process, the springs on both sides undergo elastic deformation synchronously. The spring in the deflection direction is stretched, the reverse spring is compressed, and the rotation of the limit frame causes the two springs to bend, converting the impact force generated by the swing into the elastic potential energy of the springs, effectively reducing equipment wear and noise.

[0011] Further, the sorting and blanking assembly includes an elastic frame. The elastic frame is fixedly connected to the top of the bottom plate, and the elastic frame is arranged on the side of the conveyor belt away from the driving box. A stepped block is fixedly connected to the inner side surface of the elastic frame. A blanking frame is fixedly connected to the side of the elastic frame away from the bottom plate. There are several blanking frames, and the number of the blanking frames corresponds to that of the conveyor belt. One end of the blanking frame extends into the conveyor belt, and the end of the blanking frame inside the conveyor belt inclines away from the bottom plate. The surface of the blanking frame is slidably connected to the surface of the driving rod. The outer side surface of the buffer ring is fixedly connected to the surface of the blanking frame. The macadamia nuts pass through the sorting holes and then fall onto the inclined surface of the blanking frame and then roll down along the blanking frame. The blanking frames corresponding to the conveyor belt achieve graded blanking. When the driving rod swings with the conveyor belt, the blanking frame slidably connected to it swings synchronously. Through the guiding action of the inclined surface of the blanking frame, this swing causes the macadamia nuts to roll irregularly during the downward sliding process, effectively avoiding the smoothness of blanking caused by stacking or jamming of the fruits. The elastic material and hollow structure of the buffer ring and the elastic frame absorb the impact force of the swing of the driving rod while providing flexible support for the blanking frame to prevent the fruits from colliding and breaking due to violent shaking. In addition, the blanking frame swings with the driving rod, that is, swings synchronously with the conveyor belt, ensuring that fruits of different specifications can accurately fall into the corresponding grading areas.

[0012] Furthermore, a corrugated plate is fixedly connected to the bottom of the inner side surface of the blanking frame, and a number of corrugated plates are evenly distributed. A number of support plates are arranged directly below the blanking frames. The support plates are fixedly connected to the side of the stepped block away from the bottom plate. The side of the support plate away from the stepped block is fixedly connected to the inner side surface of the elastic frame. The support plate is made of an elastic material. The two sides of the support plate are recessed inward, and the support plate is hollow. The setting of the corrugated plate enables the fruits to disperse along the undulating surface of the corrugated plate when sliding down the blanking frame, effectively preventing the fruits from piling up in the blanking frame due to a single sliding path and reducing the mutual collision between the fruits. With its inwardly recessed hollow structure, the elastic support plate buffers when receiving the vibration transmitted by the blanking frame. When the driving rod drives the blanking frame to swing or the fruits quickly impact the bottom of the blanking frame, the elastic material and the hollow cavity of the support plate deform synergistically, converting the vibration energy into elastic potential energy. This not only reduces the vibration amplitude of the blanking frame, preventing the fruits from being thrown out of the blanking area due to excessive vibration, but also avoids rigid collision between the fruits and the blanking frame, thus protecting the outer shell of the fruits from damage.

[0013] The beneficial effects of the present invention are as follows: 1. By setting the conveying mechanism, that is, a number of stepwise-distributed conveyor belts, there is a vertical height between adjacent conveyor belts. When the macadamia nuts fall from the previous conveyor belt to the next one, due to the drop caused by the vertical height difference, the macadamia nuts are scattered and flipped to a certain extent during the falling process, so that the macadamia nuts are evenly spread on the surface of the conveyor belt, improving the screening effect.

[0014] 2. By setting the baffle plates, the gaps between adjacent conveyor belts can be filled. When the irregularly shaped macadamia nuts bounce after hitting the conveyor belt and are likely to be bounced into the gaps, the baffle plates can ensure that each macadamia nut passes through the sorting holes for screening. A number of baffle plates are arranged at the intervals between the conveyor belts, and both sides of the baffle plates are slidably connected to the two conveyor belts respectively. Moreover, the adjacent conveyor belts are stepwise distributed, which means that one baffle plate is arranged on each of the upper and lower sides at both ends of the conveyor belt. As the conveyor belt moves, one end of the conveyor belt moves upward and the other end moves downward, resulting in the conveyor belt swinging and driving the macadamia nuts to jolt, achieving a better sorting effect.

[0015] 3. By setting the buffer ring, when the conveyor belt swings, the driving rod will be squeezed against the inner wall of the buffer ring due to the displacement of the conveyor belt. The recessed part of the buffer ring provides a larger buffer space through deformation, enabling the driving rod to have a more flexible movement range during the swinging process, avoiding the conveyor belt from jamming or the driving rod from deforming due to hard collision. The hollow elastic material absorbs the impact force generated by the swinging of the driving rod, converting mechanical energy into elastic potential energy, and effectively reducing the impact of the swinging on the overall structure of the equipment.

[0016] 4. By providing a driving component and a ball-joint type limiting structure composed of a limiting frame and a ball head rod, while ensuring the stability of the driving box, the present invention endows it with flexible swinging freedom. When the conveyor belt swings under the action of the convex strips and the baffle, the spherical surface of the ball head rod forms a sliding constraint with the inner wall of the limiting frame, which can not only adjust the posture following the swinging direction of the conveyor belt, but also constrain the conveyor belt through the boundary limitation of the limiting frame, allowing the conveyor belt to move up and down and deflect horizontally in three-dimensional space, causing the conveyor belt to produce regular undulations, making the macadamia nuts jump under the dual action of gravity and inertia, and enabling the fruits to readjust their postures, greatly increasing the probability of passing through the corresponding apertures.

[0017] 5. By providing a sorting and discharging component, when the driving rod swings with the conveyor belt, the discharging frame slidably connected thereto shakes synchronously. This kind of swinging, through the guiding action of the inclined surface of the discharging frame, promotes the irregular rolling of the macadamia nuts during the downward sliding process, effectively avoiding the unsmooth discharging caused by the stacking or jamming of the fruits. The elastic materials and hollow structures of the buffer ring and the elastic frame absorb the impact force of the swinging of the driving rod while providing flexible support for the discharging frame, preventing the fruits from being damaged due to violent shaking. In addition, the discharging frame swings with the driving rod, that is, swings synchronously with the conveyor belt, ensuring that fruits of different specifications can accurately fall into the corresponding grading areas.

[0018] 5. By providing a corrugated plate, when the fruits slide down along the discharging frame, the fruits are dispersed along the undulating surface of the corrugated plate, effectively avoiding the accumulation of fruits in the discharging frame due to a single sliding path and reducing the mutual collision between the fruits at the same time. With its inwardly concave hollow structure, the elastic support plate buffers when receiving the vibration transmitted by the discharging frame. When the driving rod drives the discharging frame to swing, or the fruits quickly impact the bottom of the discharging frame, the elastic material and the hollow cavity of the support plate cooperate to deform, converting the vibration energy into elastic potential energy, which not only reduces the vibration amplitude of the discharging frame, preventing the fruits from being thrown out of the discharging area due to excessive vibration, but also avoids the rigid collision between the fruits and the discharging frame and damaging the outer shell.

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0022] Example 1, please refer to Figures 1 - 5 The present invention is a macadamia nut conveying device with a sorting mechanism, comprising: Base plate 1, with bracket 2 fixedly connected to the top of base plate 1; The conveying mechanism 3 is fixedly connected to the inner side surface of the bracket 2; Among them, the conveying mechanism 3 includes: The conveyor belt 31 is arranged at the interval of the bracket 2, and the conveyor belt 31 is slidably connected to the inner side surface of the bracket 2; The conveyor belt 31 is provided with sorting holes 34 on its surface. There are a plurality of sorting holes 34 , and the sorting holes 34 are evenly distributed on the surface of the conveyor belt 31 . The drive assembly 32 is in driving connection with the inner side of the conveyor belt 31 and is fixedly connected to the outer side of the bracket 2; The sorting and unloading component 33 is arranged at the interval of the conveyor belt 31, and the sorting and unloading component 33 is arranged obliquely. The sorting and unloading component 33 is fixedly connected to the top of the bottom plate 1; Put macadamia nuts on the surface of the conveyor belt 31, start the drive assembly 32, the output end of the drive assembly 32 drives the conveyor belt 31 to transport, the conveyor belt 31 drives the macadamia nuts to transport, the macadamia nuts smaller than the sorting holes 34 pass through the conveyor belt 31, and then enter the sorting and discharging assembly 33, and finally the sorting is realized. The sorting and discharging assembly 33 is inclined and arranged inside the conveyor belt 31, and can complete the discharging and sorting under the action of the self-weight of the macadamia nuts.

[0023] A number of conveyor belts 31 are provided, and the number of conveyor belts 31 is distributed in a stepped manner along the conveying direction. Sorting holes 34 are formed on the surfaces of the number of conveyor belts 31, and the diameters of the sorting holes 34 on the surfaces of the number of conveyor belts 31 gradually decrease along the conveying direction. The sizes of the sorting holes 34 on the number of conveyor belts 31 gradually decrease, so that the smallest macadamia nuts first enter the sorting and discharging assembly 33, and then the macadamia nuts entering the sorting and discharging assembly 33 gradually increase, realizing hierarchical screening. The number of stepped conveyor belts 31 makes there be a vertical height between adjacent conveyor belts 31. When the macadamia nuts reach the next conveyor belt 31 from the previous conveyor belt 31, due to the drop generated by the vertical height difference, the macadamia nuts are scattered and flipped to a certain extent during the falling process, so that the macadamia nuts are evenly spread on the surface of the conveyor belt 31, improving the screening effect.

[0024] Baffles 36 are arranged at the intervals between adjacent conveyor belts 31. One side of the baffle 36 close to the bottom plate 1 is inclined towards the conveying direction. The two sides of the baffle 36 are respectively slidably connected to the outer sides of the two conveyor belts 31. The center of the baffle 36 is rotatably connected to a central rod 37 through a torsion spring. The end of the central rod 37 is fixedly connected to the inner side surface of the bracket 2. The setting of the baffle 36 can fill the gap between adjacent conveyor belts 31, and avoid that when the irregularly shaped macadamia nuts hit the conveyor belt 31 and rebound, they are bounced into the gap, ensuring that each macadamia nut passes through the screening of the sorting holes 34.

[0025] A convex strip 35 is fixedly connected to the outer side surface of the conveyor belt 31. There are several convex strips 35, and the several convex strips 35 are evenly distributed on the surface of the conveyor belt 31. The convex strips 35 are arranged at the intervals between adjacent sorting holes 34. As the conveyor belt 31 is transmitted, the convex strip 35 contacts the baffle 36, causing the conveyor belt 31 to move. Baffles 36 are arranged at the intervals of several conveyor belts 31. Both sides of the baffle 36 are slidably connected to two conveyor belts 31 respectively, and adjacent conveyor belts 31 are distributed in a stepped manner, which means that a baffle 36 is arranged on the upper and lower sides at both ends of the conveyor belt 31. As the conveyor belt 31 is transmitted, one end of the conveyor belt 31 goes up and the other end goes down, thus causing the conveyor belt 31 to swing, driving the macadamia nuts to jolt, achieving a better sorting effect. At the same time, the baffle 36 is torsionally spring-connected to the central rod 37. When the force of the convex strip 35 pressing the baffle 36 exceeds a predetermined threshold, the baffle 36 rotates. After the convex strip 35 passes through, the baffle 36 resets under the action of the elastic force of the torsion spring, thus not affecting the transmission of the conveyor belt 31. And when the convex strip 35 presses the baffle 36, the initial elastic force of the torsion spring provides a certain resistance, so that the baffle 36 will not rotate easily, thus ensuring that the conveyor belt 31 swings with a sufficient amplitude, further improving the sorting efficiency. When the pressing force of the convex strip 35 exceeds the elastic force threshold preset by the torsion spring, the baffle 36 rotates. This process plays a buffering role, preventing the conveyor belt 31 from generating excessive swing or mechanical damage due to continuous obstruction.

[0026] Embodiment 2. Please refer to Figures 1 - 10 , the driving assembly 32 includes a driving box 321. There are several driving boxes 321, and the number of driving boxes 321 corresponds to the conveyor belt 31. The driving boxes 321 are arranged outside the bracket 2. Driving rods 322 are symmetrically arranged on one side of the driving box 321 close to the conveyor belt 31, and the driving rods 322 are fixedly connected to the output ends of the driving boxes 321. The two driving rods 322 are respectively arranged at both ends of the conveyor belt 31, and the driving rods 322 are in transmission connection with the inner side surface of the conveyor belt 31. When the driving box 321 is started, the output end of the driving box 321 drives the driving rod 322 to rotate, thereby driving the conveyor belt 31 to transmit.

[0027] Buffer rings 323 are provided on both sides of the conveyor belt 31. The inner side surface of the buffer ring 323 is rotatably connected to the surface of the driving rod 322. The outer side surface of the buffer ring 323 is fixedly connected to the inner side surface of the bracket 2. The two ends of the buffer ring 323 are recessed inward. The buffer ring 323 is hollow and made of an elastic material. When the conveyor belt 31 does not swing, the driving rod 322 rotates inside the buffer ring 323. When the conveyor belt 31 swings, the driving rod 322 will be squeezed against the inner wall of the buffer ring 323 due to the displacement of the conveyor belt 31. The recessed part of the buffer ring 323 provides a larger buffer space through deformation, enabling the driving rod 322 to have a more flexible range of movement during the swinging process, avoiding the conveyor belt 31 from jamming or the driving rod 322 from deforming due to hard collisions. The hollow elastic material absorbs the impact force generated by the swinging of the driving rod 322, converting mechanical energy into elastic potential energy, effectively reducing the impact of the swing on the overall structure of the equipment.

[0028] On one side of the driving box 321 close to the bracket 2, a limit frame 324 is fixedly connected. A ball head rod 325 is slidably connected to the inner side surface of the limit frame 324, and the ball head rod 325 is arranged in the middle of the limit frame 324. The side of the ball head rod 325 away from the driving box 321 is fixedly connected to the outer side surface of the bracket 2. When the conveyor belt 31 swings, it drives the driving rod 322 to swing, drives the driving box 321 to swing, and then drives the limit frame 324 to swing. The limit frame 324 rotates outside the ball head rod 325. The ball hinge type limit structure formed by the limit frame 324 and the ball head rod 325 gives it a flexible degree of freedom of swinging while ensuring the stability of the driving box 321. When the conveyor belt 31 swings under the action of the convex strip 35 and the baffle 36, the spherical surface of the ball head rod 325 forms a sliding constraint with multiple point contacts with the inner wall of the limit frame 324. It can not only adjust its posture following the swinging direction of the conveyor belt 31, but also restrict the conveyor belt 31 through the boundary limitation of the limit frame 324, allowing the conveyor belt 31 to move up and down and deflect horizontally in three-dimensional space, causing the conveyor belt 31 to produce regular undulations, making the macadamia nuts jump under the dual action of gravity and inertia, and enabling the fruits to readjust their postures, greatly increasing the probability of passing through the corresponding aperture.

[0029] A spring 326 is fixedly connected to the surface of the ball head rod 325. The springs 326 are symmetrically arranged with the ball head rod 325 as the center. The two ends of the two springs 326 away from the ball head rod 325 are respectively fixedly connected to the upper and lower ends of the inner side surface of the limit frame 324. When the driving box 321 deviates, the limit frame 324 slides along the spherical surface of the ball head rod 325. During this process, the two side springs 326 synchronously undergo elastic deformation. The spring 326 in the deviation direction is stretched, and the reverse spring 326 is compressed. The rotation of the limit frame 324 causes the two springs 326 to bend, converting the impact force generated by the swing into the elastic potential energy of the spring 326, effectively reducing equipment wear and noise.

[0030] The sorting and blanking assembly 33 includes an elastic frame 332. The elastic frame 332 is fixedly connected to the top of the bottom plate 1, and the elastic frame 332 is arranged on the side of the conveyor belt 31 away from the drive box 321. A stepped block 333 is fixedly connected to the inner side surface of the elastic frame 332. A blanking frame 331 is fixedly connected to the side of the elastic frame 332 away from the bottom plate 1. There are several blanking frames 331, and the number of the blanking frames 331 corresponds to that of the conveyor belt 31. One end of the blanking frame 331 extends into the conveyor belt 31, and the end of the blanking frame 331 located inside the conveyor belt 31 inclines away from the bottom plate 1. The surface of the blanking frame 331 is slidably connected to the surface of the driving rod 322. The outer side surface of the buffer ring 323 is fixedly connected to the surface of the blanking frame 331. The macadamia nuts pass through the sorting holes 34 and then fall onto the inclined surface of the blanking frame 331, and then roll down along the blanking frame 331. The blanking frames 331 corresponding to the conveyor belt 31 achieve graded blanking. When the driving rod 322 swings with the conveyor belt 31, the blanking frame 331 slidably connected to it swings synchronously. Through the guiding effect of the inclined surface of the blanking frame 331, this swing causes the macadamia nuts to roll irregularly during the downward sliding process, effectively avoiding the smoothness of blanking caused by stacking or jamming of the fruits. The elastic materials and hollow structures of the buffer ring 323 and the elastic frame 332 absorb the impact force of the swing of the driving rod 322 while providing flexible support for the blanking frame 331 to prevent the fruits from colliding and breaking due to violent shaking. In addition, the blanking frame 331 swings with the driving rod 322, that is, swings synchronously with the conveyor belt 31, ensuring that fruits of different specifications can accurately fall into the corresponding grading areas.

[0031] A corrugated plate 334 is fixedly connected to the bottom of the inner side surface of the blanking frame 331, and several corrugated plates 334 are evenly distributed. Several support plates 335 are arranged directly below several blanking frames 331. The support plates 335 are fixedly connected to the side of the stepped block 333 away from the bottom plate 1. The side of the support plate 335 away from the stepped block 333 is fixedly connected to the inner side surface of the elastic frame 332. The support plates 335 are made of elastic materials. The two sides of the support plates 335 are recessed inward, and the support plates 335 are hollow. The setting of the corrugated plate 334 enables the fruits to disperse along the undulating surface of the corrugated plate 334 when sliding down along the blanking frame 331, effectively avoiding the accumulation of fruits in the blanking frame 331 due to a single sliding path and reducing the mutual collision between the fruits. With its inwardly recessed hollow structure, the elastic support plate 335 buffers when receiving the vibration transmitted by the blanking frame 331. When the driving rod 322 drives the blanking frame 331 to swing, or the fruits quickly impact the bottom of the blanking frame 331, the elastic material and the hollow cavity of the support plate 335 deform synergistically, converting the vibration energy into elastic potential energy, which not only reduces the vibration amplitude of the blanking frame 331, preventing the fruits from being thrown out of the blanking area due to excessive vibration, but also avoids the rigid collision between the fruits and the blanking frame 331 and damaging the outer shell.

[0032] During use, place macadamia nuts on the surface of the conveyor belt 31, and then start the driving assembly 32. The driving box 321 drives the driving rod 322 to rotate, driving the conveyor belt 31 to convey. A number of stepwise distributed conveyor belts 31 drive the fruits to move. Fruits smaller than the sorting holes 34 fall into the lower sorting and discharging assembly 33 below. During the transmission of the convex strips 35 on the outer side surface of the conveyor belt 31, they contact the baffle 36 connected to the central rod 37 through a torsion spring. Under the resistance of the torsion spring, the conveyor belt 31 swings, driving the fruits to jolt. When the force exerted by the convex strip 35 on the baffle 36 exceeds a predetermined threshold, the baffle 36 rotates. After the convex strip 35 passes through, the baffle 36 resets under the elastic force of the torsion spring. The conveyor belt 31 swings, driving the driving rod 322 to swing, driving the driving box 321 to swing, and then driving the limit frame 324 to swing. The limit frame 324 rotates outside the ball head rod 325. When the driving box 321 deviates, the limit frame 324 slides along the spherical surface of the ball head rod 325. During this process, the two side springs 326 synchronously undergo elastic deformation. The spring 326 in the deviation direction is stretched, the reverse spring 326 is compressed, and the rotation of the limit frame 324 causes the two springs 326 to bend, converting the impact force generated by the swing into the elastic potential energy of the spring 326, effectively reducing equipment wear and noise.
