For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0041] The feeding system 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] Reference Figure 1 According to a feeding system 100 according to an embodiment of the present invention, the feeding system 100 includes: a transport component 21 and a buffer component 30.

[0043] The transport assembly 21 has an inlet side and an outlet side, with the outlet side being lower than the inlet side. The transport assembly 21 is used to guide materials from the inlet side to the outlet side. The buffer assembly 30 is movably disposed on the outlet side. The buffer assembly 30 has a first position that blocks the outlet side and a second position that releases the outlet side.

[0044] The material enters the transport component 21 from the entry side and is discharged from the discharge side to the outside of the transport component 21. The discharged material may subsequently enter the next level of process or enter the finished product bucket.

[0045] Among them, the height of the discharge side is lower than the height of the entry side, and the weight of the material is used to help the material move to another position.

[0046] In the related art, materials are usually transported using conveyor belts. However, when the materials to be transported are various foods, such as fruits, walnut kernels, etc., there is a certain height difference between adjacent conveyor belts, which may cause damage to the materials.

[0047] In the embodiment of the present invention, a buffer assembly 30 is provided on the discharge side, and the buffer assembly 30 provides a certain buffer to prevent the material from being deformed or damaged due to the impact force.

[0048] Among them, the buffer component 30 can be movably arranged on the discharge side, the buffer component 30 is located in the first position, the buffer component 30 is on the moving path of the material, the buffer component 30 exerts a buffering effect and absorbs the impact of the material, the buffer component 30 is located in the second position, the buffer component 30 is away from the moving path, wherein the buffer component 30 can be pushed away by the material, or driven away from the moving path by other driving forces, and the material is detached from the transport component 21.

[0049] In the above solution, by providing the buffer component 30 that switches between the first position and the second position, the buffer effect is improved compared with the solution of the buffer curtain in the related art.

[0050] Specifically, the transport component 21 can be constructed as an open type, such as a conveyor belt, and correspondingly, the entry side is the conveying starting point of the conveyor belt, and the discharge side is the conveying ending point of the conveyor belt; or, the transport component 21 can also be constructed as a closed type, such as a transport channel, the entry side is the entrance of the transport channel, and the discharge side is the outlet of the transport channel.

[0051] According to the feeding system 100 of the embodiment of the present invention, a buffer component 30 is arranged on the discharge side with a lower height. The buffer component 30 provides a certain buffer to prevent the material from being deformed or damaged due to the impact force, and the buffer component 30 is arranged to switch between the first position and the second position, which further improves the buffering effect and further reduces the probability of deformation or damage of the material.

[0052] In some embodiments, the buffer assembly 30 includes a movable member and a buffer member 32 .

[0053] The movable member is movably arranged at the discharge side. The buffer member 32 is arranged at the movable end of the movable member and at a side of the movable member facing the inlet side.

[0054] Among them, the movable parts can move to switch positions, and use their own weight to provide buffering capacity for the material, further reducing the probability of deformation or damage of the material.

[0055] In some specific embodiments, the movable member is configured as a moving member that moves and switches between the first position and the second position. In other embodiments, the movable member is configured as a rotating member 31 that rotates around a rotation axis and switches between the first position and the second position.

[0056] Reference Figure 1 In some specific embodiments, the movable member is configured as a rotating member 31 , the rotating member 31 is rotatably disposed on the discharge side, and the buffer member is disposed at a rotating end of the rotating member 31 .

[0057] The buffer member 32 is disposed on a side of the rotating member 31 facing the entry side. When the buffer assembly 30 is located at the first position, the front of the buffer member 32 faces the direction of falling materials, thereby providing a buffering effect.

[0058] In the above solution, the rotating member 31 cooperates with the buffer member 32 to realize automatic return in a rotating manner, which is convenient for realizing reciprocating cycles and simplifies the structure.

[0059] Specifically, the rotating member 31 may be made of a hard plate material for easy molding.

[0060] In some specific embodiments, the buffer member 32 is constructed as a flexible buffer layer, such as an elastic rubber layer, which is convenient for molding and implementation.

[0061] In other specific embodiments, the buffer member 32 is constructed as a flexible wire, and the flexible wire is multiple. Specifically, the multiple flexible wires are arranged in an array to provide a certain buffering capacity, further improving the buffering capacity. For example, the flexible wire is directly constructed on the rotating member 31, with the surface of the flexible wire facing the material; or, refer to the attached Figure 9A mounting plate 311 perpendicular to the rotating member 31 is provided on one side of the rotating member 31 extending toward the material. At least one end of the flexible wire is constructed on the mounting plate 311 to form a flexible wire array of multiple rows and columns. The side of the flexible wire is used to withstand the impact force of the material. In a preferred embodiment, one end of the flexible wire is fixed on the mounting plate 311 and the other end is in a free state. In some embodiments, the two ends of the flexible wire are respectively fixed on a mounting plate 311.

[0062] Reference Figure 1 In some embodiments, there are multiple rotating members 31, and the multiple rotating members 31 rotate around the same rotating axis.

[0063] Among them, multiple rotating parts 31 are associated and rotate around the same rotating axis. Multiple rotating parts 31 can rotate under the drive of a motor, or under the elastic force of a torsion spring, or rotate under the condition of their own weight. That is to say, multiple rotating parts 31 rotate synchronously or remain stationary. The rotating parts 31 can rotate clockwise or counterclockwise, and multiple buffer parts 32 are located on the same side of the corresponding rotating parts 31.

[0064] In the above scheme, by setting up multiple associated rotating parts 31, the corresponding buffer parts 32 can contact different materials in turn, avoiding the direct passage of materials in the rotating gap, and shortening the stroke of a single rotating part 31 while realizing the reciprocating rotation of the rotating part 31, thereby improving work efficiency.

[0065] For example, there may be two rotating members 31 and two buffer members 32, with the two buffer members 32 correspondingly disposed on the rotating members 31. The two rotating members 31 are disposed on opposite sides of the rotating shaft, and in a clockwise direction, the two buffer members 32 are located on the same side of the corresponding two rotating members 31. Alternatively, there may be three rotating members 31, with two adjacent rotating members 31 spaced 120 degrees apart. There may also be three buffer members 32, with the three buffer members 32 correspondingly disposed on the rotating members 31, and in a clockwise direction, the three buffer members 32 are located on the same side of the corresponding two rotating members 31. Of course, there may be more rotating members 31, which will not be detailed here.

[0066] In some embodiments, the rotating member 31 has the inertia to rotate to the first position to stop the material. The feeding system 100 also includes a conveyor belt 11, which is arranged below the discharge side. The conveyor belt 11 is provided with a plurality of separation spaces 112, and the separation spaces 112 are used to accommodate the material.

[0067] Among them, the space on the conveyor belt 11 is divided into multiple separation spaces 112, and the materials are relatively independent. At the same time, the rotating part 31 stops the material and blocks the material on the transport component 21. The conveyor belt 11 cooperates with the rotating part 31, and the rotating part 31 blocks and releases the material, and transports the material regularly to the separation space 112.

[0068] In the above solution, the materials are arranged regularly and orderly through the cooperation between the rotating member 31 and the conveyor belt 11.

[0069] Specifically, the rotating member 31 may be stationary in the first position due to its own weight. For example, in the absence of external force, the rotating member 31 automatically droops, and the material is stopped under the action of the rotating member 31's own weight; the rotating member 31 may also be stationary in the first position due to the action of a torsion spring, and the material is stopped under the elastic force of the torsion spring; the rotating member 31 may also be stationary in the first position due to the action of a control motor, and the control motor is provided with an electromagnetic brake to stop the material.

[0070] The rotating member 31 is driven to rotate to the second position by an external mechanism, such as a motor, to release the material into the separation space 112. During the subsequent grading operation, it can ensure that the material in the specific separation space 112 is removed, completely avoiding the removal of other materials, and ensuring accurate grading operation.

[0071] In some specific embodiments, the rotating member 31 is rotatably disposed on the support base. An elastic member is further disposed on the support base. The elastic member is connected to the rotating member 31 so that the rotating member 31 has the inertia to rotate to the first position.

[0072] Specifically, the elastic member may be a torsion spring, one end of which is connected to the support base, and the other end of which is connected to the rotating member 31 . The torsion spring applies a force to the rotating member 31 , so that the rotating member 31 has the inertia to rotate to the first position.

[0073] In other embodiments, the rotating member 31 includes a mounting portion and a counterweight portion.

[0074] The buffer member 32 is mounted on the mounting portion. The counterweight portion is located on a side of the mounting portion away from the buffer member 32, so that when the buffer assembly 30 is located at the first position, the center of gravity of the buffer assembly 30 is located at the lowest point.

[0075] Among them, the counterweight part is located on the side of the mounting part away from the buffer part 32, so as to balance the overall weight of the buffer assembly 30, so that when the buffer assembly 30 is in the first position, the center of gravity of the buffer assembly 30 is at the lowest point. When the buffer assembly 30 is in the second position, it is affected by its own gravity, and the weight automatically moves to the lowest point, and the buffer assembly 30 automatically returns to the first position.

[0076] In the above solution, the return of the rotating member 31 is achieved by its own weight, which simplifies the structure and reduces the number of parts.

[0077] In some embodiments, the conveyor belt 11 is provided with a plurality of partitions 111, and the plurality of partitions 111 are spaced apart along the extension direction of the conveyor belt 11, and two adjacent partitions 111 jointly define a separation space 112, and the rotating member 31 has a mating portion, and the partition 111 is provided with a pushing portion, and the pushing portion cooperates with the mating portion to rotate the buffer assembly 30 to the second position.

[0078] Among them, multiple partitions 111 divide the space into multiple separation spaces 112, and the materials are relatively independent. At the same time, a pushing part is provided on the partition 111, and the matching part has a matching relationship with the matching part on the rotating part 31. The pushing part contacts the matching part and applies a force to the matching part, thereby pushing the buffer component 30, and the buffer component 30 is usually located in the first position. The buffer component 30 switches from the first position to the second position, and the material is transferred from the transport component 21 to the separation space 112.

[0079] In the above scheme, a plurality of separation spaces 112 are separated by setting a partition 111, and the separation spaces 112 are used to independently transport materials, thereby reducing problems such as material errors and contact, and avoiding the problem of other materials being carried out synchronously, thereby improving the accuracy of material sorting. In addition, the partition 111 cooperates with the rotating part 31, and the rotating part 31 does not need to be equipped with an additional drive device, thereby simplifying the structure and reducing the space occupied.

[0080] It should be noted that the buffer assembly 30 has the inertia to rotate to the first position. When the pushing portion does not contact the mating portion, the buffer assembly 30 automatically returns to the first position, thereby stopping the material. The buffer assembly 30 can automatically return under the influence of its own gravity, or it can automatically return by being connected to an elastic part.

[0081] Reference Figure 1 、 Figure 2 In some specific embodiments, the conveyor belt 11 is wound around a plurality of drive wheels 115 , which are spaced apart along the length of the conveyor belt 11 . A plurality of collecting members 121 are provided on one side of the conveyor belt 11 , and the collecting members 121 are sequentially distributed along the length. An operating member 122 is provided on the other side of the conveyor belt 11 , and the operating member 122 is adjacent to the conveyor belt 11 to apply force to the material so that the material is transferred into the collecting member 121 .

[0082] Among them, the driving wheel 115 drives the conveyor belt 11 to move, and the working conveyor belt 11 transports materials. The operating part 122 applies force to the materials on the conveyor belt 11, such as spraying air to the materials or applying thrust to transfer the materials to the collecting part 121 to complete the sorting.

[0083] In some embodiments, there may be only one driving wheel 115 , which supports the conveyor belt via at least one supporting wheel, and drives the conveyor belt to rotate via the driving wheel 115 .

[0084] In the above solution, through the cooperation between the operating member 122 and the collecting member 121, the material is placed on the conveyor belt 11, so that the material can be sorted multiple times, making the material classification more accurate and improving product quality and added value.

[0085] In other embodiments, the buffer assembly 30 further includes: a control motor, the output end of the control motor is connected to the rotating member 31, and an electromagnetic brake is provided on the control motor, which is connected to the output end to lock the output end when the control motor stops working.

[0086] The output end of the control motor is connected to the rotating member 31, actively driving the rotating member 31 to rotate. The output end is connected to an electromagnetic brake. When the control motor stops working, the output end cannot rotate and the rotating member 31 stops.

[0087] In the above scheme, by setting a control motor to actively drive the rotating member 31 to rotate, and providing an electromagnetic brake to lock the output end, the rotating member 31 can be fixed in one position, for example, the buffer component 30 is stationary in the first position, so that the falling material is stationary on the transport component 21, thereby improving work efficiency.

[0088] Specifically, the feeding system 100 is configured as a part of a material sorting device.

[0089] According to the material sorting device of the embodiment of the present invention, a buffer component 30 is arranged on the discharge side with a lower height. The buffer component 30 provides a certain buffer to prevent the material from being deformed or damaged due to the impact force, and the buffer component 30 is arranged to switch between the first position and the second position, which further improves the buffering effect and further reduces the probability of deformation or damage of the material.

[0090] Reference Figures 1 to 3 In some specific embodiments, the feeding system 100 further includes: a sorting component and a control component.

[0091] The sorting assembly includes a conveyor belt 11 and a sorting structure 12. The conveyor belt 11 is used to transport materials. A transport assembly 21 is adapted to supply materials to the conveyor belt 11. The transport assembly 21 has a notch 211. A first identification structure 22 performs multi-angle circumferential identification of materials passing through the notch 211 to obtain first identification information of the materials. Based on this first identification information, the control unit controls the sorting structure 12 to perform sorting operations on the materials.

[0092] It should be noted that the feeding system 100 is usually used to process a large amount of materials. The materials can be fruits or nuts, such as walnut kernels, almonds, pistachios, etc., or other agricultural products, such as pepper, star anise, chili, etc. The feeding system 100 realizes accurate classification of materials according to preset standards, and can use the sorting structure 12 on the conveyor belt 11 to perform multiple grading and rejection operations on the materials based on the recognition results of the first recognition structure 22 according to product requirements to meet efficient and refined grading requirements.

[0093] Among them, the transport component 21 transports the material to the conveyor belt 11, the first identification structure 22 obtains the first identification information of the material, and the first identification information is transmitted to the control component. When the material moves onto the conveyor belt 11, the control component controls the sorting structure 12 adjacent to the conveyor belt 11 to operate the material, and materials with the same or similar first identification information are collected together, thereby classifying a large amount of material into multiple categories.

[0094] Specifically, the first identification information is information on the surface or inside of the material, including but not limited to the following information: material size information, material surface spot information, material surface texture information, material surface or internal mildew information, material material information, etc., among which material surface defects can generally be detected using conventional visible light cameras, and some special information requires the use of special cameras such as hyperspectral, infrared, and ultraviolet light for detection and identification.

[0095] Among them, the first identification structure 22 can be a camera, a camera, or other optical elements; the first identification structure 22 is equipped with a light source, and the light source is one or more of visible light, infrared light, hyperspectral light, ultraviolet light, and X-ray. Generally, it should include at least a visible light camera, and other cameras can be configured according to specific needs, and a suitable optical system can be adaptively built according to needs. The specific optical system will not be repeated in this embodiment.

[0096] In the related art, the channel-type color sorter identifies the material when it leaves the structure supporting its movement and is in a suspended state. The bad material is blown away by the gas. Since the material moves in the air for a long time after leaving the channel or returns to the channel, the movement state will be uncontrollable. Therefore, the material identification and sorting can only be completed within a very limited window period. Generally, there is only one sorting opportunity. At this time, in order to ensure the sorting effect, the pressure of the nozzle used for rejection will be increased to a certain extent, resulting in a certain carry-out ratio, that is, there will be some good materials among the bad materials removed, which means that the material can only be sorted once and multi-level sorting cannot be performed; some color sorters use a transparent conveyor belt to drive the material through the identification area, and identification cameras are set on both sides of the conveyor belt to detect and identify the material, but the surface of the transparent conveyor belt is easily dirty, resulting in misjudgment of the material identification results.

[0097] In this embodiment of the present invention, the first identification structure 22 performs multi-angle identification of the material's circumference at the gap 211. For example, referring to the identification structure of a channel-type color sorter, front and rear sorting boxes can be positioned on either side of the gap 211 to perform multi-angle identification, essentially covering the entire surface of the material. For example, optical inspection can be performed on the front and back halves of the material, essentially covering the sides of the material, thereby obtaining accurate product grading information. This improves overall material identification accuracy and facilitates accurate material classification. Furthermore, while the material is on the conveyor belt 11, the sorting structure 12 is controlled to perform operations on the material based on the acquired first identification information. This allows for multiple sorting operations, resulting in more accurate material classification and improved product quality and added value.

[0098] Specifically, there are at least two first recognition structures 22, each located on opposite sides of the gap 211. When the material passes through the gap 211, the first recognition structures 22 on both sides respectively acquire information about the material from multiple angles, thereby acquiring a greater amount of information. The material has a certain initial velocity, which allows it to pass smoothly through the gap 211.

[0099] For example, refer to Figure 1 The transport component 21 is set horizontally, and has a certain initial speed when reaching the gap 211, and is thrown from the end of the transport component 21, and passes through the gap 211 under the action of inertia; or, the front side of the gap 211 is set obliquely upward, and the material moves from front to back, and has a certain initial speed when reaching the gap 211, and passes through the gap 211 under the action of inertia and is thrown to the back side of the gap 211; or, the transport component 21 is set obliquely downward, and the material can also be thrown from the front side of the gap 211 through the gap 211 to the back side of the gap 211 under the action of inertia.

[0100] More specifically, at least two first identification structures 22 are respectively arranged on the side of the gap 211 close to the sorting structure 12 and the side away from the sorting structure 12, thereby forming a front and rear sorting box structure. The specific positions of the two first identification structures 22 relative to the gap 211 can be adaptively set according to the identification requirements, such as being respectively arranged on both sides of the gap 211 in the horizontal direction, the up and down direction, or the diagonal direction to obtain information on the two opposite sides of the material.

[0101] It should be noted that a buffer component 30 is also provided at the end of the transport component 21. It can be understood that the material has a certain speed when passing through the gap 211. The present invention provides a certain buffer for the material by setting the buffer component 30 to avoid deformation or damage of the material due to impact force, thereby improving the accuracy of sorting. Based on the function of the buffer component 30, the movement speed of the material falling onto the conveyor belt 11 is reduced, so that the material can be smoothly transferred to the conveyor belt 11 to prevent the order and position from being disordered, so that multiple grading and sorting operations can be accurately performed on the material on the conveyor belt 11 through one-time identification at the gap 211.

[0102] According to the feeding system 100 of the embodiment of the present invention, multi-angle identification is performed, and more surface information is obtained, thereby improving the overall identification accuracy of the material and improving the accuracy of judgment. At the same time, when the material is on the conveyor belt 11, the sorting structure 12 is controlled to perform operations on the material according to the obtained first identification information, and multiple sortings can be performed, so that the material classification is more accurate, and the product quality and added value are improved. A buffer component 30 is provided at the end of the transport component 21, and the design of the matching notch 211 provides a certain buffer for the material to avoid deformation or damage of the material due to impact force, thereby further improving the sorting accuracy, and at the same time, it adapts to materials with irregular surfaces and increases the scope of application.

[0103] Reference Figures 1 to 4 In some embodiments, the transport component 21 includes a first transport member 212 and a second transport member 213 .

[0104] The first conveying member 212 is used to transport materials. The second conveying member 213 is disposed obliquely between the first conveying member 212 and the conveyor belt 11. The first conveying member 212 and the second conveying member 213 together define a gap 211. Materials are ejected from the end of the first conveying member 212 through the gap 211 and transferred to the second conveying member 213. The buffer assembly 30 is disposed between the second conveying member 213 and the conveyor belt 11.

[0105] In some specific embodiments, the first conveying member 212 is located on the side of the second conveying member 213 facing away from the conveyor belt 11. The end of the first conveying member 212 is higher than the second conveying member 213. The first conveying member 212 throws the material onto the second conveying member 213, and the second conveying member 213 transports the material to the conveyor belt 11. Specifically, the conveying starting point of the first conveying member 212 is the aforementioned entry side, and the conveying ending point of the second conveying member 213 is the aforementioned discharge side.

[0106] In the above scheme, the second conveying member 213 is set to be inclined downward to guide the material to the conveyor belt 11, so that the second conveying member 213 can better receive the material thrown into the air. It can be understood that the tangential speed of the material can be set to be the same or similar to the inclination angle of the second conveying member 213, thereby reducing the impact force of the material falling on the second conveying member 213 and reducing the probability of material damage.

[0107] Specifically, the second conveying member 213 extends in the direction of the first conveying member 212. The second conveying member 213 can be constructed as a first slide. The first slide is arranged obliquely downward. The material on the first slide automatically slides onto the second conveying member 213. The second conveying member 213 can also be constructed as a conveyor belt. The conveyor belt can be set horizontally. The horizontally set conveyor belt allows the material to have a certain speed and throw the material into the air. The conveyor belt can also be set at an angle. The inclined conveyor belt allows the material to have a certain speed and can also throw the material into the air.

[0108] In some embodiments, the first conveying member 212 is configured as a first slideway inclined downward.

[0109] Specifically, the first slide extends along the extension direction of the second conveying member 213 , and the material slides downward on the first slide. The falling material passes through the notch 211 and falls tangentially onto the second conveying member 213 .

[0110] In the above scheme, by setting the first slide to extend along the extension direction of the second conveying member 213, the material can fall tangentially onto the second conveying member 213, thereby reducing the impact force of the material falling on the second conveying member 213, reducing the probability of material damage, simplifying the overall structure, and reducing costs.

[0111] It is understandable that the first slide does not need to strictly correspond to the second conveying member 213 , and the first slide may have a slight angular difference with the extension direction of the second conveying member 213 .

[0112] In other embodiments, the first conveying member 212 is configured as a horizontally arranged conveyor belt, which drives the material and throws the material to the second conveying member 213 .

[0113] The conveyor belt is an active driving structure, which drives the material to move and transports the material to the second conveying member 213 .

[0114] In the above solution, by constructing the first conveying member 212 as a conveyor belt, which is an actively driven structure, the overall efficiency is improved and the probability of materials falling from the gap 211 is reduced.

[0115] Specifically, the conveyor belt can be arranged horizontally, and the horizontally arranged conveyor belt allows the material to have a certain speed and throw the material into the air.

[0116] In other embodiments, the conveyor belt may also be arranged at an angle. The inclined conveyor belt allows the material to have a certain speed and can also throw the material into the air.

[0117] Reference Figures 1 to 5 In some embodiments, the feeding system 100 further includes: a hopper 50 and a vibration assembly 60 .

[0118] The hopper 50 has an inlet 51 and an outlet 52. The inlet 51 is used to supply material to the hopper 50. A vibration assembly 60 is disposed between the outlet 52 and the transport assembly 21 to vibrate and disperse the material before supplying it to the transport assembly 21. The outlet 52 is provided with an adjustable baffle 53, which is movably mounted on the outlet 52 to adjust the size of the outlet 52.

[0119] The material enters the hopper 50 from the feed port 51 and is discharged from the discharge port 52 to the outside of the hopper 50 . The material first passes through the vibration component 60 , which vibrates to evenly disperse the material and then moves it to the transport component 21 .

[0120] In the above solution, the vibration assembly 60 is provided to disperse the material, making it uniform, thereby facilitating subsequent identification and sorting, and improving sorting accuracy. Furthermore, an adjustable baffle 53 is provided at the discharge port 52. The adjustable baffle 53 controls the size of the discharge port 52, thereby limiting the outflow rate of the material and adjusting the arrangement and stacking of the material, thereby avoiding material stacking and further ensuring a uniform outflow of the material.

[0121] Specifically, the vibration assembly 60 includes a vibration plate and a vibration motor, the vibration motor is connected to the vibration plate to drive the vibration plate to vibrate. More specifically, there are multiple vibration plates, which are arranged in sequence and the heights of the multiple vibration plates decrease in sequence to improve the uniformity effect.

[0122] Specifically, the adjustable baffle 53 can be configured to be adjustable up and down, or left and right. Both of the above solutions can control the size of the discharge port 52, thereby limiting the outflow speed of the material.

[0123] More specifically, the discharge port 52 is constructed as a necking structure, and the necking structure is tilted downward, so that the material can flow more smoothly.

[0124] Reference Figures 1 to 5 In some embodiments, the feeding system 100 further includes a feeding assembly 70, which is disposed between the transport assembly 21 and the vibration assembly 60. The feeding assembly 70 includes a receiving trough 71 adapted to accommodate a predetermined amount of material. The receiving trough 71 is configured to move between the transport assembly 21 and the vibration assembly 60 to transport the material to the transport assembly 21. A second slide 72 is disposed between the feeding assembly 70 and the vibration assembly 60, and a first buffer curtain 721 is disposed at the slide outlet.

[0125] The feed assembly 70 is located downstream of the vibration assembly 60. After being vibrated and dispersed by the vibration assembly 60, the material falls into the receiving groove 71, which then transports the material to the transport assembly 21. The second slide 72 is located between the feed assembly 70 and the vibration assembly 60, and the second slide 72 acts as an intermediate bridge, transporting the material from the vibration assembly 60 to the feed assembly 70.

[0126] In the above scheme, a trough 71 is provided to accommodate the material, and the material accommodated in the trough 71 is a preset amount, so that the material is further evenly divided, which is convenient for subsequent sorting. A second slide 72 is provided to make the material neat. At the same time, a first buffer curtain 721 is provided at the slide outlet. The first buffer curtain 721 is used to reduce the impact of the material and avoid collision damage to the material.

[0127] Specifically, the accommodating groove 71 is suitable for accommodating a preset amount of material. The preset amount can be based on quantity. For example, the accommodating groove 71 is suitable for accommodating a single walnut, or the accommodating groove 71 is suitable for accommodating two walnuts. It can also be based on volume, which will not be repeated here.

[0128] Specifically, the slide entrance of the second slide 72 is higher than the slide exit, which facilitates transportation.

[0129] Reference Figures 1 to 5 In some specific embodiments, the second slide 72 is adjacent to a dust blowing cavity 722 , and the dust blowing cavity 722 corresponds to the output position of the vibration component 60 to blow air and remove dust from the output position of the vibration component 60 .

[0130] Specifically, the receiving tank 71 is set according to the size and shape of the material. Figure 2 、 Figure 7 , multiple rows of accommodating grooves 71 are evenly arranged on the feeding assembly 70 (for ease of observation, only some accommodating grooves 71 are shown in the figure, and other accommodating grooves 71 are hidden). The feeding assembly 70 is arranged in the horizontal direction. The feeding assembly 70 includes chain links 73 on both sides of the conveying direction, and uses connecting rods 74 to connect the chain links 73 on both sides. The connecting rods 74 are evenly arranged along the loop formed by the chain links 73. Wedge blocks 75 are fixed on the connecting rods 74, and conical protrusions are formed on the surface of the wedge blocks 75. Accommodating grooves 71 are formed between the protruding positions of adjacent wedge blocks 75, wherein the shape of the protrusions can be arbitrary, and the accommodating grooves 71 can also be concave spaces formed by the settlement of the surface of the wedge blocks 75.

[0131] Furthermore, the feeding assembly 70 also includes a scraper 77, which is horizontally arranged above the receiving tank 71 and inclined relative to the conveying direction. It is used to scrape the overstacked materials from the receiving tank 71 and collect them from the gaps between adjacent connecting rods 74, and finally return them to the hopper 50. A material receiving belt 76 is provided below the scraper 77 and is perpendicular to the conveying direction to output and collect the scraped materials.

[0132] In other embodiments, a conveyor belt is provided between the transport component 21 and the vibration component 60 to transport materials from the vibration component 60 to the transport component 21 , which has a simple and practical structure.

[0133] In some embodiments, the buffer component 30 has a first position and a second position. When the buffer component 30 is in the first position, the buffer component 30 blocks the moving path of the material to buffer the material. When the buffer component 30 is in the second position, the moving path is released.

[0134] In some embodiments, the first position is adjacent to a second identification structure, which is used to obtain second identification information of the material stationary on the transport component 21, and the second identification structure is electrically connected to the control component, which controls the sorting structure 12 to operate the material according to the first identification information and the second identification information, such as pushing the material into the corresponding collecting component 121 or other operations.

[0135] Among them, the second identification structure is used to obtain the second identification information, the second identification structure is electrically connected to the control component, and the control component controls the sorting structure 12 to operate the material according to the first identification information and the second identification information. The control component can compare the first identification information with the second identification information to avoid problems such as sequence changes and material stacking when the material falls through the gap 211; at the same time, the control component can determine whether multiple materials are stacked through the second identification information, which may cause the subsequent separation space 112 to contain materials exceeding the preset amount, resulting in problems and reducing the sorting accuracy.

[0136] It should be noted that the second identification structure is used to obtain second identification information of the material stationary on the transport component 21. The buffer component 30 stops the material, so that the material remains stationary on the transport component 21, which facilitates the identification of the second identification structure.

[0137] In the above scheme, by setting up a second identification structure to obtain second identification information, the control component controls the sorting structure 12 to operate the material according to the first identification information and the second identification information, which can avoid problems such as sequence changes and material stacking when the material falls through the gap 211, and at the same time avoid carry-out problems, thereby improving the sorting accuracy.

[0138] Specifically, the second identification information includes morphological information of the material, such as shape, color, size, etc.

[0139] Specifically, in the subsequent sorting process, the materials that fail to match the sequential material form information will not be sorted and will be returned to the hopper 50 .

[0140] Reference Figure 3 、 Figure 8 In some embodiments, the sorting structure 12 includes: a plurality of the aforementioned collecting components 121 and the aforementioned operating components 122 .

[0141] The plurality of collecting elements 121 are sequentially distributed along the conveying direction of the conveyor belt 11. The operating element 122 is adjacent to the conveyor belt 11 and is electrically connected to the control element. The operating element 122 applies force to the materials under the control of the control element to collect the materials with the same first identification information into the same collecting element 121.

[0142] The entrances of the plurality of collecting elements 121 are sequentially distributed along the transport path of the conveyor belt 11. The operating element 122 acts toward the entrance of the collecting element 121 to sort the corresponding grade of materials into the corresponding collecting element 121. When the materials move to the corresponding collecting element 121, the operating element 122 applies force to the materials, transferring the materials into the collecting element 121.

[0143] In the above solution, a large amount of materials are divided into multiple categories by cooperating with the operating member 122 and the plurality of collecting members 121, and the materials are further subdivided, thereby achieving refined sorting of products.

[0144] For example, the category is level, and there are at least three collecting pieces 121, which divide a large amount of materials into three levels, and the three collecting pieces 121 collect materials of different levels respectively; or, there are four or more collecting pieces 121, which will not be repeated here.

[0145] Specifically, the operating part 122 can be a nozzle that sprays gas on the material to transfer the material into the collecting part 121; or, the operating part 122 can be a push rod that applies thrust to the material to push the material into the collecting part 121; or, the operating part 122 can be a manipulator that grabs the material and transfers the material into the collecting part 121.

[0146] Specifically, multiple operating members 122 can be provided, and the operating members 122 correspond one-to-one to the collecting members 121; or, the number of operating members 122 is less than the number of collecting members 121, and a single operating member 122 corresponds to multiple collecting members 121, and the operating member 122 can be moved to complete the operation.

[0147] In other embodiments, the plurality of collecting members 121 are movable, and the collecting members 121 move to corresponding materials to collect the materials.

[0148] In some specific embodiments, the operating member 122 is configured as an air nozzle or a push rod.

[0149] Among them, the operating part 122 can be an air nozzle or a push rod. When the operating part 122 is an air nozzle, the air nozzle sprays gas on the material to push the material to move. When the operating part 122 is a push rod, the push rod pushes the material to move. The implementation method is simple and practical.

[0150] In some embodiments, the operating member 122 is configured to be movable. The operating member 122 is suitable for moving to a position corresponding to the material and applying force to the material to collect the material into the corresponding collecting member 121 .

[0151] The operating member 122 is adjacent to the conveyor belt 11 , and the operating member 122 can be moved to a position corresponding to the material and exert an action on the material to transfer the material to the corresponding collecting member 121 .

[0152] In the above solution, by providing a movable operating member 122, the operating member 122 corresponds to a plurality of collecting members 121, and the plurality of collecting members 121 share the same operating member 122, thereby reducing the number of parts and optimizing the structure.

[0153] In other embodiments, there are multiple operating members 122 , and the operating members 122 are arranged corresponding to the collecting members 121 to apply force to the material and collect the material into the corresponding collecting member 121 .

[0154] The collecting members 121 correspond to the operating members 122 in a one-to-one manner. When the material moves to the corresponding collecting member 121 , the corresponding operating member 122 is actuated to transfer the material into the corresponding collecting member 121 .

[0155] In the above solution, by providing a plurality of operating members 122 , the operating members 122 correspond one-to-one to the collecting members 121 , thereby improving the accuracy of sorting and reducing the probability of misoperation of the operating members 122 .

[0156] Reference Figure 8 More specifically, the operating member 122 corresponds to the middle position of the conveyor belt 11, so that the corresponding collecting member 121 can be arranged on opposite sides of the conveyor belt 11, making the overall structure more compact.

[0157] Furthermore, multiple collection members 121 corresponding to the same conveyor belt 11 are staggered, making the structure more compact. Accordingly, gaps are provided between the multiple conveyor belts 11 to accommodate the collection members 121 and operating members 122. Each operating member 122 can apply force to the conveyor belts 11 on either side. For example, the operating members 122 are nozzles. The first nozzle sprays air to the left, acting on the material on the left conveyor belt 11, while the adjacent second nozzle sprays air to the right, acting on the collected material on the right side of the conveyor belt 11. It is understood that the arrangement of the first and second nozzles can be repeated along the extension direction of the conveyor belt 11.

[0158] In some specific embodiments, there are multiple conveyor belts 11, and the multiple conveyor belts 11 are arranged in parallel, thereby improving the sorting efficiency.

[0159] Specifically, the collecting member 121 is a collecting hopper. The conveyor belt 11 is adjacent to a receiving drum 113 for receiving materials. Below the receiving drum 113 is a receiving belt 114 perpendicular to the conveyor belt 11. The sorted materials are collected from the side and can simultaneously collect materials from multiple parallel conveyor belts 11. The surface of the receiving belt 114 can be provided with a dividing strip as needed. The dividing strip extends in a direction perpendicular to the conveyor belt 11, dividing its surface into multiple material conveying channels, thereby being able to simultaneously convey multiple levels of materials and collect them at the end of the conveying using different collecting hoppers. Materials that cannot be effectively identified or have special conditions such as piles are collected from the end along the conveyor belt 11 and subsequently returned to the hopper 50 for re-grading by an elevator or manual operation.
