Spectral non-destructive testing has the advantages of fast detection efficiency, high detection accuracy, and no need to damage the surface of fruits and vegetables. The specific implementation process is as follows: When fruits and vegetables are irradiated with near-infrared light, different internal components of fruits and vegetables have different degrees of optical absorption and scattering for different wavelengths, and the internal spectrum will also change with the different mass fractions of the internal components of fruits and vegetables. Using this feature, the main components and their mass fractions in fruits and vegetables can be analyzed according to the characteristics of the near-infrared spectrum, so as to sort out fruits and vegetables of different grades.

It should be noted that when an element is described as "connected" to another element, it can be directly on another element, or there can be one or more centered elements therebetween. The terms "upper", "lower", "left", "right", "upper end", "lower end", "top" and "bottom" used in this specification indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0050] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0051] Please also read Figure 1 and Figure 2 ; Figure 1It is a structural schematic diagram of a fruit and vegetable conveying unit provided in an embodiment of the utility model; Figure 2 yes Figure 1 Schematic diagram of the structure of the fruit and vegetable conveying unit for spectral detection.

[0052] An embodiment of the utility model provides a fruit and vegetable conveying unit 100, comprising a connecting column 10, a supporting column 20 and a fruit cup 30, wherein the connecting column 10 and the supporting column 20 are respectively connected to opposite sides of the fruit cup 30; the fruit cup 30 comprises a receiving groove 31 and a supporting opening 32, wherein the receiving groove 31 is connected to the two supporting openings 32 and is located between the two supporting openings 32, wherein the arrangement direction of the two supporting openings 32 is consistent with the length direction of the fruit cup 30, and the arrangement direction of the connecting column 10 and the supporting column 20 is consistent with the width direction of the fruit cup 30; fruits and vegetables can be placed in the receiving groove 31, and opposite ends of the fruits and vegetables can be abutted against the side walls of the two supporting openings 32; the fruit cup 30 can rotate with the connecting column 10 as the axis, so that the fruit cup 30 is turned over with the width of the fruit cup 30 as the radius to drop the fruits.

[0053] Here, it should be noted that the fruit cup 30 can hold fruits and vegetables, such as pineapple, dragon fruit, corn, etc. The purpose of flipping the fruit cup 30 is to transport the fruits and vegetables in the fruit cup 30 to the corresponding position. To be precise, when the fruit cup 30 holds the fruits and vegetables, the fruits and vegetables on the fruit cup 30 need to be inspected and sorted. The sorting criteria can be the quality of the fruits and vegetables, the integrity of the surface of the fruits and vegetables, or the type of fruits and vegetables, etc. (not limited here). Figure 2 In this embodiment, the detection of fruits and vegetables is carried out by infrared spectroscopy. Specifically, the surface of fruits and vegetables on the fruit cup 30 is irradiated with infrared rays, and the infrared absorption spectrum of the fruits and vegetables is obtained below the fruit cup 30. The infrared absorption spectrum is analyzed and sorted to achieve the purpose of sorting fruits and vegetables.

[0054] In this embodiment, in a top view, the fruit cup 30 is roughly rectangular, the receiving groove 31 is roughly elliptical, and the opposite ends of the fruits and vegetables are respectively against the side walls of the two supporting openings 32 of the fruit cup 30, so that the fruits and vegetables are placed flat. It can be simply understood that for long or cylindrical fruits and vegetables, when the fruits and vegetables are placed on the fruit cup 30, the length direction of the fruits and vegetables is consistent with the length direction of the fruit cup 30, that is, the fruits and vegetables are placed on the fruit cup 30 in a flat posture. This arrangement helps to make the fruits and vegetables in the fruit cup 30 more stable during transportation and prevents the fruits and vegetables from falling from the fruit cup 30.

[0055] Moreover, the present solution is not only applicable to placing long or cylindrical fruits and vegetables flatly in the fruit cup 30, but also round fruits such as apples can be placed in the fruit cup 30 in a stable posture. In other words, the fruit cup 30 can be adapted to fruits of different shapes. In this embodiment, long or cylindrical fruits and vegetables are used as examples. For ease of understanding, the fruits and vegetables can be simply regarded as pineapples.

[0056] In addition, it should be further explained that, during the process of flipping and dropping fruits, the fruit and vegetable conveying unit 100 uses the length direction of the fruit cup 30 as the rotation axis and the width of the fruit cup 30 as the radius to flip and drop the fruits. The advantage of this method of dropping fruits is that the required torque is small and the impact force when the fruits and vegetables fall can be reduced, thereby avoiding damage to the fruits and vegetables.

[0057] See also Figure 3 , Figure 3 yes Figure 1 Schematic diagram of the structure of the fruit cup in the fruit and vegetable conveying unit.

[0058] In one embodiment, the fruit cup 30 includes a fruit cup plate 33 and an elastic pad 34. The elastic pad 34 is placed in the middle of the fruit cup plate 33. The side wall of the fruit cup plate 33 and the elastic pad 34 are enclosed to form a receiving groove 31. The elastic pad 34 includes a pad body 341 and a limiting portion 342. The pad body 341 is connected to the fruit cup plate 33. The limiting portion 342 is connected to the pad body 341. The limiting portion 342 is extended from the pad body 341 to the receiving groove 31, and the fruits and vegetables are against multiple limiting portions 342.

[0059] Here, it should be noted that the sorting of fruits and vegetables mainly adopts spectral non-destructive testing, and the infrared light irradiation device is used to irradiate the outer surface of fruits and vegetables (refer to Figure 5 ), the fruits and vegetables on the fruit cup 30 during transportation are irradiated with infrared light and the fruits and vegetables are sorted.

[0060] Specifically, the elastic pad 34 is made of a relatively soft material, and the elastic pad 34 is roughly elliptical. When fruits and vegetables are placed on the elastic pad 34, the elastic pad 34 will deform and form a depression to limit the position of the fruits and vegetables. Moreover, the limiting portion 342 and the pad body 341 are manufactured in one piece, and can be manufactured by injection molding to reduce production costs. When fruits and vegetables are placed in the receiving groove 31, the outer surface of the fruits and vegetables abuts against the limiting portion 342 and the pad body 341 to limit the position of the fruits and vegetables and maintain the stability of the placement posture of the fruits and vegetables during transportation.

[0061] Moreover, the plurality of limiting portions 342 are evenly distributed along the central circumference of the pad body 341 . The purpose of such arrangement is to ensure that the limiting effects on the opposite sides of the fruits and vegetables are the same when the fruits and vegetables are placed in the receiving groove 31 , thereby preventing the fruits and vegetables from falling from one side of the receiving groove 31 .

[0062] In one embodiment, the fruit cup plate 33 is provided with a first through hole 331, the cushion body 341 includes a second through hole 3411, a partition 3412 and a deformation zone 3413, the first through hole 331 is connected to the second through hole 3411; there are a plurality of partitions 3412, and the plurality of partitions 3412 are all connected to the second through hole 3411, and there is a deformation zone 3413 between any two adjacent partitions 3412, and when fruits and vegetables abut against the deformation zone 3413, the deformation zone 3413 can be deformed from the first through hole 331 to the second through hole 3411.

[0063] Here, it should be noted that the above-mentioned spectrum non-destructive testing requires not only an infrared irradiation device but also an infrared receiver, and the infrared irradiation device and the infrared receiver are respectively located on opposite sides of the fruit cup 30. In the specific testing process, the infrared irradiation device irradiates infrared rays on the surface of fruits and vegetables, and the infrared rays penetrate the fruits and vegetables and sequentially pass through the second through hole 3411 and the first through hole 331 and are then received by the infrared receiver.

[0064] If the partition groove 3412 is not provided, after the infrared ray is projected onto the surface of the fruit and penetrates the fruit, the infrared receiver can only receive the infrared ray passing through the second through hole 3411. To be precise, after the infrared ray passes through the surface of the fruit, only a part of it can pass through the second through hole 3411 and be received by the infrared receiver. In this way, the infrared ray received by the infrared receiver that penetrates the fruits and vegetables is actually uneven, that is, it can only detect the real situation of the internal part of the fruits and vegetables.

[0065] By setting the partition 3412, the infrared rays can be received not only through the path of the second through hole 3411, the first through hole 331 and the infrared receiver, but also through the path of the partition 3412, the first through hole 331 and the infrared receiver. The purpose of such setting is to make the infrared receiver receive the light signal of fruits and vegetables more uniform. Further, the fruits to be detected are cylindrical or long strip fruits and vegetables as an example, that is, the fruits and vegetables are placed in the fruit cup 30 in a flat posture. The setting of the partition 3412 makes the range of fruits and vegetables detected by this detection method larger, and the detection effect is better.

[0066] See also Figure 3 and Figure 4 , Figure 4 yes Figure 3 Schematic diagram of the structure of the fruit cup bracket in the fruit and vegetable conveying unit.

[0067] In one embodiment, the fruit cup 30 further includes a fruit cup support 35, which is connected to the fruit cup plate 33. The fruit cup support 35 includes a first connecting arm 351, a second connecting arm 352 and a third connecting arm 353. The first connecting arm 351, the second connecting arm 352 and the third connecting arm 353 are connected in sequence. The second connecting arm 352 is provided with a first rotating shaft hole 3521. The connecting column 10 passes through the first rotating shaft hole 3521, and the connecting column 10 is connected to the second connecting arm 352.

[0068] A mounting hole 332 is provided on one side of the fruit cup plate 33 away from the connecting column 10, and the supporting column 20 is installed in the mounting hole 332. The first connecting arm 351 and the third connecting arm 353 are arranged opposite to each other, and the opposite sides of the fruit cup plate 33 are rotatably connected to the first connecting arm 351 and the third connecting arm 353 respectively.

[0069] Specifically, the fruit cup holder 35 is connected to the fruit cup tray 33, and the fruit cup holder 35 is roughly a C-shaped holder. The first connecting arm 351, the second connecting arm 352 and the third connecting arm 353 can be manufactured in one piece, and the fruit cup holder 35 is roughly an axisymmetric product to reduce the design and production costs. The first rotating shaft hole 3521 is opened on the side of the second connecting arm 352 away from the first connecting arm 351, and the connecting column 10 passes through the first rotating shaft hole 3521 and is connected to the second connecting arm 352, so that during the rotation process of the fruit cup tray 33, the connecting column 10 is used as the axis, and the first connecting arm 351 is used as the rotation radius, and the side of the first connecting arm 351 away from the connecting column 10 rotates downward.

[0070] The opposite sides of the fruit cup plate 33 are rotatably connected to the first connecting arm 351 and the third connecting arm 353 respectively, and the supporting column 20 is installed on the side of the fruit cup plate 33 away from the second connecting arm 352. The purpose of this arrangement is that when the height position of the supporting column 20 changes, the side of the fruit cup plate 33 close to the supporting column 20 will tilt downward, and the corresponding side of the corresponding fruit cup bracket 35 will also tilt downward, and the fruits and vegetables in the fruit cup 30 will fall out. In practice, the fruit cup bracket 35 rotates around the connecting column 10, and no external force is required to apply pressure during this process, and the structure is simple and reliable.

Figure 7 yes Figure 1 A side view of the fruit cup of the fruit and vegetable conveying unit from another angle.

[0072] In one embodiment, a first rotating shaft 3511 is respectively disposed at one end of the first connecting arm 351 away from the second connecting arm 352 and at one end of the third connecting arm 353 away from the second connecting arm 352; a second rotating shaft hole 333 is respectively disposed at two opposite sides of the fruit cup plate 33, and a first rotating shaft 3511 passes through a corresponding second rotating shaft hole 333;

[0073] The fruit cup plate 33 further includes a first abutting portion 334 and a second abutting portion 335, which are respectively located at opposite sides of the fruit cup plate 33; a first gap 3341 is formed between the first abutting portion 334 and the first connecting arm 351, and a second gap 3351 is formed between the second abutting portion 335 and the third connecting arm 353;

[0074] After the fruit cup tray 33 rotates in one direction relative to the fruit cup support 35 , the first abutting portion 334 abuts against the first connecting arm 351 , and the second abutting portion 335 abuts against the second connecting arm 352 , so as to limit the fruit cup tray 33 from rotating relative to the fruit cup support 35 .

[0075] Specifically, the opposite sides of the fruit cup plate 33 are rotatably mounted in a second rotating shaft hole 333 through a first rotating shaft 3511, so that after the fruit cup plate 33 is loaded with fruits and vegetables, the fruit cup plate 33 is rotated under the influence of the gravity of the fruits and vegetables. During the rotation of the fruit cup plate 33, the first abutting portion 334 and the second abutting portion 335 will respectively abut against the first connecting arm 351 and the second connecting arm 352 to limit the rotation of the fruit cup plate 33, so that the weighing sensor only measures the weight of the fruit cup plate 33, the elastic pad 34 and the fruits and vegetables. The weight of the fruit cup plate 33 and the elastic pad 34 can be weighed and recorded as a fixed value before use, and finally the weighing sensor is set to reduce weight to weigh the weight of the fruits and vegetables.

[0076] If the first gap 3341 and the second gap 3351 are not provided, that is, the first abutting portion 334 and the second abutting portion 335 abut against the fruit cup support 35 before the rotation, the reading of the weighing sensor will be directly displayed. Then, when the fruits and vegetables are not placed on the fruit cup tray 33, the reading of the weighing sensor may change continuously, making it difficult to determine the weight of the fruit cup tray 33 and the elastic pad 34. When the fruits and vegetables are placed on the fruit cup tray 33, the reading of the weighing sensor changes again, which may easily lead to a large error in weighing the fruits and vegetables.

[0077] In addition, the first connecting arm 351 and the second connecting arm 352 can prevent the fruit cup plate 33 from rotating at an excessive angle, thereby preventing the fruits and vegetables in the fruit cup plate 33 from falling off.

[0078] See also Figure 8 , Figure 8 yes Figure 1 A schematic structural diagram of the fruit and vegetable conveying unit from another angle.

[0079] In one embodiment, the second connecting arm 352 includes an arm body 3522 and a pad 3523. The connecting column 10 is connected to the arm body 3522, and the pad 3523 is connected to the arm body 3522. The pad 3523 is located below the fruit cup plate 33. There is a third gap 35231 between the pad 3523 and the fruit cup plate 33. After the fruit cup plate 33 rotates in another direction relative to the fruit cup holder 35, the fruit cup plate 33 and the pad 3523 abut against each other to limit the rotation of the fruit cup plate 33 relative to the fruit cup holder 35.

[0080] Specifically, the arm body 3522 and the pad 3523 can be integrally manufactured by injection molding, the pad 3523 is located below the arm body 3522, and the pad 3523 is placed horizontally, extending from the second connecting arm 352 to the fruit cup plate 33, and the pad 3523 is substantially a V-shaped plate. There is a third gap 35231 between the pad 3523 and the bottom of the fruit cup plate 33, and the purpose of such a setting is that when fruits and vegetables are placed on the fruit cup plate 33, if the center of gravity of the fruits and vegetables is close to one side of the second connecting arm 352, then the fruit cup plate 33 will tilt toward the side close to the second connecting arm 352 until the fruit cup plate 33 abuts against the pad 3523. The pad 3523 restricts the fruit cup plate 33, so that the fruit cup plate 33 is difficult to rotate in another direction, thereby preventing the fruits and vegetables from falling off the fruit cup plate 33 too early. Moreover, it can be ensured that the fruit cup plate 33 can be tilted only after the supporting column 20 passes through the second supporting section 2302 , thereby ensuring the fruit output effect of the entire fruit and vegetable conveying unit 100 .

[0081] See also Fig. 9 , Fig.10 and Fig.11 , Fig. 9 It is a structural schematic diagram of a conveying device provided in another embodiment of the utility model; Fig.10 yes Fig. 9 A schematic structural diagram of the conveying device from another angle; Fig.11 yes Fig.10 A partial enlarged schematic diagram of the structure of part B in FIG.

[0082] The utility model also provides a conveying device 200, including the above-mentioned fruit and vegetable conveying unit 100, the conveying device 200 also includes a frame 210, a conveyor belt 220 and a supporting belt 230, the conveyor belt 220 and the supporting belt 230 are both installed on the frame 210, the supporting belt 230 includes a first supporting section 2301 and a second supporting section 2302 connected to each other, the first supporting section 2301 is horizontally arranged along the transmission direction of the conveyor belt 220, and the second supporting section 2302 is inclined downwardly arranged;

[0083] The conveyor belt 220 is connected to the connecting column 10 to drive the fruit cup 30 to move along the transmission direction of the conveyor belt 220. The supporting column 20 is against the supporting belt 230. The supporting column 20 can slide along the first supporting section 2301 to the second supporting section 2302 under the drive of the conveyor belt 220 to tilt the fruit cup 30.

[0084] Here, it should be noted that the fruit cup 30 is roughly rectangular, and the direction from the conveyor belt 220 to the supporting belt 230 is consistent with the length direction of the fruit cup 30. It can be understood that the conveyor belt 220 and the supporting belt 230 are roughly parallel and coplanar, and the supporting belt 230 is located between the conveyor belt 220 and the fruit cup 30. The direction from the connecting column 10 to the supporting column 20 is consistent with the width direction of the fruit cup 30, that is, during the transportation of the fruit cup 30, the short side (i.e., the width direction) of the fruit cup 30 is parallel to the transmission direction of the conveyor belt 220; but it is not limited to this method.

[0085] When the supporting column 20 on the fruit cup 30 slides from the first supporting section 2301 to the second supporting section 2302, one side of the fruit cup 30 will tilt downward, and the other side of the fruit cup 30 will rotate along the connecting column 10; until the supporting column 20 moves to the bottom of the second supporting section 2302, the fruit cup 30 reaches the maximum tilt angle, and the fruits and vegetables in the fruit cup 30 fall from the fruit cup 30. During the whole process, the fruit cup 30 can be tilted without using a buckle structure and a solenoid valve to provide external force, so that the fruits and vegetables in the fruit cup 30 fall, and the structure is simple and reliable, ensuring the fruit drop of the conveying device 200.

[0086] In this embodiment, the long side of the fruit cup 30 is used as the rotation axis during the tilting process of the fruit cup 30, and the short side of the fruit cup 30 is tilted downward, so that the fruit cup 30 rotates. If the short side of the fruit cup 30 is used as the rotation axis during the tilting process of the fruit cup 30, then the long side of the fruit cup 30 needs to be tilted downward, the drop of fruits and vegetables falling from the first supporting section 2301 will become larger, and the tilting length of the second supporting section 2302 needs to be lengthened, resulting in a more complicated structure.

[0087] In one embodiment, the supporting belt 230 further includes a third supporting section 2303, the third supporting section 2303 is parallel to and coplanar with the first supporting section 2301, and there is a distance between the third supporting section 2303 and the first supporting section 2301, and the conveying device 200 further includes a driving module 240 and a bearing member 250, both of which are mounted on the frame 210, and the driving module 240 is transmission-connected to the bearing member 250, the driving module 240 is connected to one side of the first supporting section 2301, and the bearing member 250 is disposed between the third supporting section 2303 and the first supporting section 2301;

[0088] The driving module 240 can drive the support member 250 to move to the first position 260, so that the support member 250 is coplanar with the first supporting section 2301, and the supporting column 20 can slide from the first supporting section 2301 to the third supporting section 2303 through the support member 250;

[0089] The driving module 240 can drive the supporting member 250 to move to the second position 270 , so that the supporting column 20 slides from the first supporting section 2301 to the second supporting section 2302 .

[0090] Specifically, the first supporting section 2301 and the third supporting section 2303 are coplanar. It can be understood that the first supporting section 2301 and the third supporting section 2303 are placed horizontally in this embodiment, and the first supporting section 2301 and the second supporting section 2302 have an inclined angle. When the driving module 240 drives the bearing member 250 to move to the first position 260, the first supporting section 2301, the bearing member 250 and the third supporting section 2303 are all located in a horizontal position, and the fruit cup 30 is driven by the connecting column 10 and moves along the path of the first supporting section 2301, the bearing member 250 and the third supporting section 2303 under the action of the conveyor belt, that is, the fruit cup 30 always maintains a horizontal position during the above process.

[0091] When the driving module 240 drives the supporting member 250 to move to the second position 270, the distance between the first supporting segment 2301 and the third supporting segment 2303 prevents the fruit cup 30 from moving from the first supporting segment 2301 to the third supporting segment 2303. Instead, the fruit cup 30 moves along the path of the first supporting segment 2301 and the second supporting segment 2302. When the supporting column 20 of the fruit cup 30 abuts against the second supporting segment 2302, since the second supporting segment 2302 and the conveyor belt 220 have an inclined angle, the fruit cup 30 will tilt at this time, and the fruits and vegetables in the fruit cup 30 will fall out, thereby achieving the effect of sorting fruits and vegetables. Here, it should be explained that when the carrier 250 is located at the first position 260, the carrier 250 is tilted, that is, the upper surface of the carrier 250 is tilted downward; when the carrier 250 is located at the second position 270, the carrier 250 is horizontally set, that is, the upper surface of the carrier 250 is horizontally set.

[0092] Specifically, when fruits and vegetables in a fruit cup 30 are detected by infrared spectrum and confirmed to need to be sorted, a corresponding carrier 250 will be driven by the driving module 240 to move from the first position 260 to the second position 270, and the fruit cup 30 passes through a corresponding second supporting section 2302 and completes tilting and fruit dropping. For fruit cups 30 that are confirmed not to need to be sorted, the fruit cups 30 will pass through the above-mentioned carriers 250, and the fruit cups 30 will move from a corresponding first supporting section 2301 to a corresponding third supporting section 2303 to prevent the fruit cups 30 from tilting and fruit dropping.

[0093] See also Fig.12 , Fig.12 yes Fig. 9 Schematic diagram of the structure of the supporting belt of the conveying device.

[0094] In this embodiment, the support belt 230 further includes a fourth support section 2304, which is tilted upward and connected to the second support section 2302, so that the fruit cup 30 assembly after the fruit has fallen can be moved upward against the fourth support section 2304 by the support column 20 to achieve the effect of resetting. In addition, the fourth support section 2304 is connected between the second support section 2302 and a first support section 2301, and a corresponding driving module 240 and a corresponding bearing member 250 (not shown in the figure) are also provided between the fourth support section 2304 and the first support section 2301 to ensure the resetting of the fruit cup 30.

[0095] See also Fig.13 , Fig.13 yes Fig.12 Schematic diagram of the structure of the driving module of the conveying device.

[0096] In one embodiment, the driving module 240 includes a driving member 2401 and a linkage assembly 2402, wherein the driving member 2401 is disposed on the frame 210, one end of the linkage assembly 2402 is hinged to the output end of the driving member 2401, and the other end of the linkage assembly 2402 is against the frame 210, one end of the bearing member 250 is rotatably connected to the frame 210, and the linkage assembly 2402 is linked with the other end of the bearing member 250;

[0097] The driving member 2401 can push the linkage component 2402 to move, and the other end of the linkage component 2402 moves accordingly. The linkage component 2402 is against the frame 210, and the linkage component 2402 is hinged to the output end of the driving member 2401. The purpose is to make the linkage component 2402 move upward away from one end of the driving member 2401; the supporting member 250 cooperates with the linkage component 2402, that is, when the linkage component 2402 rotates upward, the supporting member 250 also rotates upward to reach the first position 260.

[0098] Specifically, the driving member 2401 is a cylinder, and the driving member 2401 can drive the linkage assembly 2402 to move along the conveying direction of the conveyor belt 220; the frame 210 includes a lifting block 2101, and the distance between the lifting block 2101 and the ground gradually increases along the direction from the driving member 2401 to the linkage assembly 2402, and the lifting block 2101 and the end of the linkage assembly 2402 away from the driving member 2401 abut against each other. The purpose of such a setting is that when the linkage assembly 2402 moves in a direction away from the driving member 2401, one end of the linkage assembly 2402 is lifted by the lifting block 2101, so that one end of the bearing member 250 is lifted to the first position.

[0099] Moreover, in this embodiment, the linkage assembly 2402 includes a first linkage rod 24021 and a second linkage rod 24022, one end of the first linkage rod 24021 is connected to the output end of the driving member 2401, the other end of the first linkage rod 24021 is abutted against the lifting block 2101, and the second linkage rod 24022 is connected to the other end of the first linkage rod 24021 and the supporting member 250. The second linkage rod 24022 plays a linkage role, that is, when the other end of the first linkage rod 24021 is lifted by the lifting block 2101, the second linkage rod 24022 also moves upward, and the supporting member 250 rotates to reach the first position 260.

[0100] In some other embodiments, the linkage assembly 2402 may use a torsion spring. For another example, the linkage assembly 2402 includes a first inclined surface, and the first inclined surface is tilted downward, so that when the linkage assembly 2402 moves horizontally, the linkage assembly 2402 can rotate upward. The rotation of the above-mentioned bearing member 250 is not limited to the above-mentioned two methods, that is, the linkage assembly 2402 can be implemented by a variety of structures, which will not be described one by one here.

[0101] In one embodiment, the conveying device 200 also includes a reset member 280, which is located below the supporting member 250, one end of the reset member 280 is connected to the frame 210, and the other end of the reset member 280 is connected to the other end of the supporting member 250, so that the other end of the supporting member 250 can rotate downward from the first position 260 to reach the second position 270.

[0102] Specifically, in the present embodiment, the reset member 280 is a spring. When the driving member 2401 is started, the supporting member 250 moves to the first position, and the reset member 280, that is, the spring, is stretched; when the driving member 2401 is reset, the reset member 280 contracts and drives the supporting member 250 to descend, that is, the supporting member 250 moves to the second position; at this time, the supporting column 20 can enter the second supporting section 2302 from the first supporting section 2301, that is, the fruit cup 30 is tilted and flipped, and the reset member 280 allows the supporting member 250 to repeatedly move to the first position or the second position, so as to achieve the purpose of industrially sorting fruits and vegetables in the fruit cup 30.

[0103] Here, it should be noted that the reset member 280 is a spring, and other elastic reset structures may also be used to achieve this, which is not limited here.

[0104] See also Fig. 9The utility model also provides a sorting machine 300, including the above-mentioned conveying device 200, the sorting machine 300 also includes a transfer component 310, the transfer component includes a transfer belt 3101, and a transfer belt 3101 is correspondingly arranged under any second supporting section 2302, and the transfer belt is used to receive fruits and vegetables dropped from the fruit cup 30.

[0105] Specifically, after the fruit cup 30 is tilted, the fruits and vegetables fall from the fruit cup 30 onto the conveyor belt 3101, and the conveyor belt 3101 conveys the sorted fruits and vegetables to complete the sorting. In this embodiment, the number of conveyor belts 3101 is the same as the number of second supporting sections 2302, that is, the fruit cup 30 assembly tilted on a second supporting section 2302 will fall onto a corresponding conveyor belt 3101, thereby facilitating subsequent industrial packaging.
