Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting, and in particular to a fruit and vegetable conveying mechanism and a fruit and vegetable sorting machine. Background Technology

[0002] As people pursue a higher quality of life, more and more people are demanding higher quality fruits and vegetables, making fruit and vegetable sorting an important technology.

[0003] Fruits and vegetables need to be inspected before sorting, and this inspection requires testing each individual fruit and vegetable. When fruits and vegetables, such as cherry tomatoes, blueberries, and cherries, are transported on belt conveyors, they inevitably tend to pile up before entering the fruit and vegetable sorting machine. This piled-up fruit and vegetables, when fed into the machine by being poured from plastic frames, makes it difficult for the camera vision system to distinguish the size and color of multiple fruits and vegetables in this stacked state, leading to reduced sorting efficiency. Therefore, multiple V-shaped conveyor channels are typically used to break up the piled-up fruit and achieve individual fruit arrangement.

[0004] However, current fruit and vegetable sorting machines pre-process fruits and vegetables, such as removing branches and leaves and small fruits, and then the fruits and vegetables directly enter multiple V-shaped conveyor channels. Because the fruits and vegetables are still piled up or unevenly distributed before entering the multiple V-shaped conveyor channels, the fruits and vegetables cannot enter the multiple V-shaped conveyor channels evenly, resulting in uneven distribution of fruits and vegetables in the multiple V-shaped conveyor channels and affecting the sorting efficiency of fruits and vegetables. Utility Model Content

[0005] The present invention aims to provide a fruit and vegetable conveying mechanism and a fruit and vegetable sorting machine to solve the technical problem in the prior art that fruits and vegetables cannot enter multiple V-shaped conveying channels evenly, resulting in uneven distribution of fruits and vegetables in multiple V-shaped conveying channels and affecting the sorting efficiency of fruits and vegetables.

[0006] To solve the above-mentioned technical problems, this utility model provides a fruit and vegetable transport structure, including:

[0007] frame;

[0008] Feeding device;

[0009] Pretreatment device;

[0010] A pre-arrangement device, including a pre-arranged conveyor belt;

[0011] V-shaped transmission channel;

[0012] The feeding device, the pretreatment device, the pre-arrangement device, and the V-shaped transmission channel are all installed on the frame and arranged sequentially along the first direction. The pre-arrangement transmission belt is used to transport fruits and vegetables along the first direction. The width of the pre-arrangement transmission belt remains unchanged in the first direction. The width direction of the pre-arrangement transmission belt is perpendicular to the first direction. The output end of the pre-arrangement transmission belt is connected to the input end of multiple V-shaped transmission channels. Each V-shaped transmission channel can transport fruits and vegetables along the first direction.

[0013] Through the above structure, fruits and vegetables pass through the feeding device, pre-treatment device, and pre-arrangement device in sequence, and then enter the V-shaped transmission channel. The width of the pre-arrangement conveyor belt remains unchanged in the first direction. The output end of the pre-arrangement conveyor belt is connected to the input end of multiple V-shaped transmission channels. After entering the pre-arrangement conveyor belt, the fruits and vegetables can be laid flat at the pre-arrangement conveyor belt to reduce the stacking of fruits and vegetables, so that the fruits and vegetables can enter the input end of multiple V-shaped transmission channels evenly.

[0014] In some embodiments, the feeding device further includes a first driving component, a second driving component, a first partition, a first feeding conveyor belt, and a second feeding conveyor belt. The first feeding conveyor belt and the second feeding conveyor belt are arranged side by side along a second direction perpendicular to the first direction. The first partition is located between the first feeding conveyor belt and the second feeding conveyor belt. The first driving component is connected to the first feeding conveyor belt and is used to drive the first feeding conveyor belt to transport fruits and vegetables along the first direction. The second driving component is connected to the second feeding conveyor belt and is used to drive the second feeding conveyor belt to transport fruits and vegetables along the first direction. Along the second direction, the width of both the first feeding conveyor belt and the second feeding conveyor belt remains unchanged. The width direction of both the first feeding conveyor belt and the width direction of the second feeding conveyor belt are perpendicular to the first direction.

[0015] The above structure employs two drive components to avoid the problem that the drive shaft of a single drive component is too long and its strength is insufficient, which would lead to poor transmission performance of the first and second feeding conveyor belts.

[0016] In some embodiments, the pre-arrangement device further includes a third drive assembly, a fourth drive assembly, and a second partition. The pre-arrangement conveyor belt includes a first pre-arrangement conveyor belt and a second pre-arrangement conveyor belt, which are arranged side by side along the second direction. The second partition is located between the first pre-arrangement conveyor belt and the second pre-arrangement conveyor belt. The third drive assembly is connected to the first pre-arrangement conveyor belt and is used to drive the first pre-arrangement conveyor belt to transport fruits and vegetables along the first direction. The fourth drive assembly is connected to the second pre-arrangement conveyor belt and is used to drive the second pre-arrangement conveyor belt to transport fruits and vegetables along the first direction. Along the first direction, the widths of both the first pre-arrangement conveyor belt and the second pre-arrangement conveyor belt remain constant.

[0017] The above structure employs two drive components to avoid the problem of insufficient strength and excessively long drive shafts in a single drive component, which could lead to poor conveying performance of the first and second pre-arranged conveyor belts. The first and second pre-arranged conveyor belts are arranged side-by-side to ensure that fruits and vegetables passing through the small fruit removal device fall evenly onto both belts, guaranteeing efficient fruit and vegetable transport.

[0018] In some embodiments, along the first direction, the position of the first pre-arranged conveyor belt corresponds to the position of the first feeding conveyor belt, and the position of the second pre-arranged conveyor belt corresponds to the position of the second feeding conveyor belt. Along the first direction, the width of the first pre-arranged conveyor belt is the same as and remains unchanged with the width of the first feeding conveyor belt, and the width of the second pre-arranged conveyor belt is the same as and remains unchanged with the width of the second feeding conveyor belt.

[0019] With the above structure, most of the fruits and vegetables located on the first feeding conveyor belt will be transported to the first pre-arranged conveyor belt, and most of the fruits and vegetables located on the second feeding conveyor belt will be transported to the second pre-arranged conveyor belt, so as to maintain a good fruit and vegetable transport effect. Moreover, the driving force directions of the first drive assembly and the third drive assembly are the same, and the driving force directions of the second drive assembly and the fourth drive assembly are the same, reducing the number of transmission structures and making the fruit and vegetable transport mechanism compact.

[0020] In some embodiments, the pre-arrangement device further includes a fruit and vegetable flow restrictor. The opposite sides of the fruit and vegetable flow restrictor are respectively connected to the output ends of the first pre-arrangement conveyor belt and the second pre-arrangement conveyor belt. The fruit and vegetable flow restrictor is located on the side of the first pre-arrangement conveyor belt away from the small fruit removal device. The fruit and vegetable flow restrictor has a V-shaped notch. The opening of the V-shaped notch gradually increases along the first direction. There are multiple V-shaped notches, and each V-shaped notch is connected to a corresponding V-shaped transmission channel.

[0021] With the above structure, only one fruit or vegetable can pass through the V-shaped gap. Other fruits and vegetables will be blocked by the side wall of the V-shaped gap, so as to prevent multiple fruits and vegetables from falling into the V-shaped transmission channel at the same time and stacking up.

[0022] In some embodiments, the pretreatment apparatus includes a branch and leaf removal device and a small fruit removal device, which are arranged sequentially along the first direction. The branch and leaf removal device includes a first branch and leaf removal driving component, a second branch and leaf removal driving component, a first branch and leaf removal conveyor belt, a second branch and leaf removal conveyor belt, a bellows, a first fan, a second fan, and a transfer conveyor belt. The first branch and leaf removal driving component is connected to the first branch and leaf removal conveyor belt and is used to drive the first branch and leaf removal conveyor belt to transport fruits and vegetables along the first direction. The second branch and leaf removal driving component is connected to the second branch and leaf removal conveyor belt and is used to drive the second branch and leaf removal conveyor belt to transport fruits and vegetables along the first direction. For transporting fruits and vegetables, both the first and second branch and leaf removal conveyor belts have first through holes. A bellows is mounted on the frame and located above the first and second branch and leaf removal conveyor belts. A first fan and a second fan are both mounted on the frame. The first and second fans blow gas towards the first and second branch and leaf removal conveyor belts respectively, allowing the gas to enter the bellows through the first through holes. The output end of the bellows is connected to the input end of the transfer conveyor belt, which is mounted on the frame and located below the first and second branch and leaf removal conveyor belts.

[0023] The above structure employs two fans located on opposite sides of the air box to ensure effective airflow over the leaf removal conveyor belt; using one air box instead of multiple air boxes simplifies the structure.

[0024] In some embodiments, along the first direction, the position of the first branch removal conveyor belt corresponds to the position of the first feeding conveyor belt, and the position of the second branch removal conveyor belt corresponds to the position of the second feeding conveyor belt. Along the first direction, the width of the first branch removal conveyor belt is the same as and remains unchanged with the width of the first feeding conveyor belt, and the width of the second branch removal conveyor belt is the same as and remains unchanged with the width of the second feeding conveyor belt.

[0025] The above structure ensures that the driving force directions of the first branch and leaf removal drive assembly and the first drive assembly are consistent, and the driving force directions of the second branch and leaf removal drive assembly and the second drive assembly are consistent, reducing the number of transmission structures and making the fruit and vegetable conveying mechanism more compact.

[0026] In some embodiments, the small fruit removal device includes a first small fruit removal driving component, a second small fruit removal driving component, a third partition, a first small fruit removal conveyor belt, and a second small fruit removal conveyor belt. The first and second small fruit removal conveyor belts are arranged side by side along the second direction. The third partition is located between the first and second small fruit removal conveyor belts. The first small fruit removal driving component is connected to the first small fruit removal conveyor belt and is used to drive the first small fruit removal conveyor belt to transport fruits and vegetables along the first direction. The second small fruit removal driving component is connected to the second small fruit removal conveyor belt and is used to drive the second small fruit removal conveyor belt to transport fruits and vegetables along the first direction. Along the first direction, the width of both the first and second small fruit removal conveyor belts remains constant. Both the first and second small fruit removal conveyor belts have a second through hole.

[0027] The above structure employs a first small fruit rejection drive assembly and a second small fruit rejection drive assembly to avoid the poor transmission effect of the first and second small fruit rejection conveyor belts due to the excessive length and insufficient strength of the drive shaft of a single drive assembly.

[0028] In some embodiments, along the first direction, the position of the first branch and leaf removal conveyor belt corresponds to the position of the first small fruit removal conveyor belt, and the position of the second branch and leaf removal conveyor belt corresponds to the position of the second small fruit removal conveyor belt. Along the first direction, the width of the first branch and leaf removal conveyor belt is the same as and remains unchanged with the width of the first small fruit removal conveyor belt, and the width of the second branch and leaf removal conveyor belt is the same as and remains unchanged with the width of the second small fruit removal conveyor belt.

[0029] With the above structure, the driving force directions of the first branch and leaf removal drive component and the first small fruit removal drive component are the same, and the driving force directions of the second branch and leaf removal drive component and the second small fruit removal drive component are the same, reducing the number of transmission structures and making the fruit and vegetable conveying mechanism more compact.

[0030] This utility model also provides a fruit and vegetable sorting machine, including the fruit and vegetable conveying mechanism described in any of the above embodiments.

[0031] Compared with the prior art, in this embodiment of the utility model, fruits and vegetables pass through a feeding device, a pre-treatment device, and a pre-arrangement device in sequence, and then enter a V-shaped transmission channel. The width of the pre-arrangement conveyor belt remains unchanged in the first direction. The output end of the pre-arrangement conveyor belt is connected to the input end of multiple V-shaped transmission channels. After the fruits and vegetables enter the pre-arrangement conveyor belt, they can be laid flat at the pre-arrangement conveyor belt to reduce the stacking of fruits and vegetables, so that the fruits and vegetables can enter the input end of multiple V-shaped transmission channels evenly.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0047] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a fruit and vegetable conveying mechanism provided in one embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of the pre-arrangement device.

[0048] An embodiment of the present invention provides a fruit and vegetable conveying mechanism 100, including a frame 10, a feeding device 20, a pre-processing device, a pre-arranging device 50, and a V-shaped conveying channel 60. The pre-arranging device 50 includes a pre-arranged conveyor belt 51. The feeding device 20, the pre-processing device, the pre-arranging device 50, and the V-shaped conveying channel 60 are all installed on the frame 10 and arranged sequentially along a first direction 70. The pre-arranged conveyor belt 51 is used to transport fruits and vegetables along the first direction 70. The width of the pre-arranged conveyor belt 51 remains unchanged in the first direction 70. The width direction of the pre-arranged conveyor belt 51 is perpendicular to the first direction 70. The output end of the pre-arranged conveyor belt 51 is connected to the input end of a plurality of V-shaped conveying channels 60. Each V-shaped conveying channel 60 transports fruits and vegetables along the first direction 70.

[0049] Specifically, fruits and vegetables sequentially pass through the feeding device 20, pre-treatment device, and pre-arranging device 50, and then enter the V-shaped conveyor channel 60. The width of the pre-arranging conveyor belt 51 remains constant in the first direction 70. The output end of the pre-arranging conveyor belt 51 is connected to the input ends of multiple V-shaped conveyor channels 60. After entering the pre-arranging conveyor belt 51, the fruits and vegetables can be laid flat, reducing stacking and ensuring even distribution to the input ends of the multiple V-shaped conveyor channels 60. The pre-arranging conveyor belt 51 transports fruits and vegetables along the first direction 70. It can be understood that the pre-arranging conveyor belt 51 only transports in one direction, and the drive device only needs to provide driving force in one direction. This eliminates the need for a transmission mechanism to achieve transport in multiple directions, avoiding structural complexity and reducing manufacturing costs.

[0050] See Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 3 yes Figure 2 A side view of the pre-arrangement device. Figure 4 yes Figure 1 A schematic diagram of the feeding device.

[0051] In one embodiment, the feeding device 20 further includes a first driving component 21, a second driving component 22, a first partition 23, a first feeding conveyor belt 24, and a second feeding conveyor belt 25. The first feeding conveyor belt 24 and the second feeding conveyor belt 25 are arranged side by side along a second direction 80 perpendicular to the first direction 70. The first partition 23 is located between the first feeding conveyor belt 24 and the second feeding conveyor belt 25. The first driving component 21 is connected to the first feeding conveyor belt 24 and is used to drive the first feeding conveyor belt 24 to transport fruits and vegetables along the first direction 70. The second driving component 22 is connected to the second feeding conveyor belt 25 and is used to drive the second feeding conveyor belt 25 to transport fruits and vegetables along the first direction 70. Along the first direction 70, the width of the first feeding conveyor belt 24 and the width of the second feeding conveyor belt 25 remain unchanged. The width direction of the first feeding conveyor belt 24 and the width direction of the second feeding conveyor belt 25 are perpendicular to the first direction 70.

[0052] Specifically, the first drive assembly 21 drives the first feeding conveyor belt 24, and the second drive assembly 22 drives the second feeding conveyor belt 25. The first partition 23 isolates the first feeding conveyor belt 24 and the second feeding conveyor belt 25 from each other. The first feeding conveyor belt 24 and the second feeding conveyor belt 25 can move independently to transport fruits and vegetables, avoiding interference between them. Two drive assemblies are used to avoid the problem of insufficient strength of a single drive shaft leading to poor transmission efficiency of the first feeding conveyor belt 24 and the second feeding conveyor belt 25.

[0053] Moreover, the width of the first feeding conveyor belt 24 and the width of the second feeding conveyor belt 25 remain unchanged along the first direction 70. Both the first feeding conveyor belt 24 and the second feeding conveyor belt 25 transport fruits and vegetables along the first direction 70. The first feeding conveyor belt 24 and the second feeding conveyor belt 25 are generally rectangular, making the structure of the feeding device 20 more compact.

[0054] Both the first drive assembly 21 and the second drive assembly 22 may include a motor and a rotating roller. The first feeding conveyor belt 24 and the second feeding conveyor belt 25 are respectively wound around at least two rotating rollers. The motor drives the rotating rollers to rotate, so that the first feeding conveyor belt 24 and the second feeding conveyor belt 25 respectively transport fruits and vegetables along the first direction.

[0055] In one embodiment, the pre-arrangement device 50 further includes a third drive assembly 52, a fourth drive assembly, and a second partition 54. The pre-arrangement conveyor belt 51 includes a first pre-arrangement conveyor belt 511 and a second pre-arrangement conveyor belt 512, which are arranged side by side along a second direction 80. The second partition 54 is located between the first pre-arrangement conveyor belt 511 and the second pre-arrangement conveyor belt 512. The third drive assembly 52 is connected to the first pre-arrangement conveyor belt 511 and is used to drive the first pre-arrangement conveyor belt 511 to transport fruits and vegetables along a first direction 70. The fourth drive assembly is connected to the second pre-arrangement conveyor belt 512 and is used to drive the second pre-arrangement conveyor belt 512 to transport fruits and vegetables along the first direction 70. Along the first direction 70, the width of the first pre-arrangement conveyor belt 511 and the width of the second pre-arrangement conveyor belt 512 remain unchanged.

[0056] Specifically, two drive components are used to avoid the problem that the drive shaft of a single drive component is too long and its strength is insufficient, which would lead to poor transmission performance of the first pre-arranged conveyor belt 511 and the second pre-arranged conveyor belt 512. The first pre-arranged conveyor belt 511 and the second pre-arranged conveyor belt 512 are arranged side by side so that when the fruits and vegetables passing through the small fruit removal device 40 fall into the first pre-arranged conveyor belt 511 and the second pre-arranged conveyor belt 512, they can be laid out flat, reducing the stacking of fruits and vegetables, and allowing the fruits and vegetables to enter the input end of the multiple V-shaped transmission channels 60 evenly.

[0057] Along the first direction 70, the width of the first pre-arranged conveyor belt 511 and the width of the second pre-arranged conveyor belt 512 remain unchanged. Both the first pre-arranged conveyor belt 511 and the second pre-arranged conveyor belt 512 transport fruits and vegetables along the first direction 70, which makes the first pre-arranged conveyor belt 511 and the second pre-arranged conveyor belt 512 generally rectangular, making the structure of the pre-arrangement device 50 more compact.

[0058] Both the third drive assembly 52 and the fourth drive assembly can include a motor and a rotating roller. The first pre-arranged conveyor belt 511 and the second pre-arranged conveyor belt 512 are respectively wound around at least two rotating rollers. The motor drives the rotating rollers to rotate, so that the first pre-arranged conveyor belt 511 and the second pre-arranged conveyor belt 512 respectively transport fruits and vegetables along the first direction.

[0059] The first feeding conveyor belt 24, the second feeding conveyor belt 25, the first pre-arranged conveyor belt 511, and the second pre-arranged conveyor belt 512 can all be conveyor belts.

[0060] See Figure 1 , Figure 2 and Figure 4In one embodiment, along the first direction 70, the position of the first pre-arranged conveyor belt 511 corresponds to the position of the first feeding conveyor belt 24, and the position of the second pre-arranged conveyor belt 512 corresponds to the position of the second feeding conveyor belt 25; along the first direction 70, the width of the first pre-arranged conveyor belt 511 is the same as and remains unchanged with the width of the first feeding conveyor belt 24, and the width of the second pre-arranged conveyor belt 512 is the same as and remains unchanged with the width of the second feeding conveyor belt 25.

[0061] Specifically, the first pre-arranged conveyor belt 511 and the first feeding conveyor belt 24 are both located on the same side of the first partition 23, while the second pre-arranged conveyor belt 512 and the second feeding conveyor belt 25 are both located on the other side of the second partition 54. This arrangement ensures that most of the fruits and vegetables located on the first feeding conveyor belt 24 are conveyed to the first pre-arranged conveyor belt 511, and most of the fruits and vegetables located on the second feeding conveyor belt 25 are conveyed to the second pre-arranged conveyor belt 512, maintaining a good fruit and vegetable conveying effect. Furthermore, the driving force directions of the first drive assembly 21 and the third drive assembly 52 are consistent, as are the driving force directions of the second drive assembly 22 and the fourth drive assembly, reducing the number of transmission structures and making the fruit and vegetable conveying mechanism 100 more compact.

[0062] In one embodiment, the pre-arrangement device 50 further includes a fruit and vegetable flow restrictor 55, which is located at the output end of the first pre-arrangement conveyor belt 511 and the output end of the second pre-arrangement conveyor belt 512. The fruit and vegetable flow restrictor 55 has a V-shaped notch 551, the opening of the V-shaped notch 551 gradually increases along the first direction 70, and there are multiple V-shaped notches 551, each V-shaped notch 551 being connected to a corresponding V-shaped transmission channel 60.

[0063] Specifically, after passing through the first pre-arranged conveyor belt 511 and the second pre-arranged conveyor belt 512, the fruits and vegetables will fall from the V-shaped notch 551 onto a corresponding V-shaped conveying channel 60. If multiple fruits and vegetables reach a V-shaped notch 551 at the same time, only one fruit or vegetable can pass through the V-shaped notch 551. The other fruits and vegetables will be blocked by the side wall of the V-shaped notch 551 to prevent multiple fruits and vegetables from piling up in the V-shaped conveying channel 60 at the same time.

[0064] The output ends of the first pre-arranged conveyor belt 511 and the second pre-arranged conveyor belt 512 are each connected to a fruit and vegetable flow restrictor 55. The sidewall of each V-shaped notch 551 is correspondingly provided with the sidewall of a corresponding V-shaped transmission channel 60.

[0065] See Figure 5 , Figure 6 and Figure 7 , Figure 5 yes Figure 1 Schematic diagram of the device for removing branches and leaves; Figure 6 yes Figure 5 A side view of the middle branch and leaf removal device; Figure 7 yes Figure 5 A schematic diagram of the structure from another side of the branch and leaf removal device.

[0066] In one embodiment, the pretreatment device includes a branch and leaf removal device 30 and a small fruit removal device 40, which are arranged sequentially along a first direction 70. The branch and leaf removal device 30 includes a first branch and leaf removal drive assembly 31, a second branch and leaf removal drive assembly 32, a first branch and leaf removal conveyor belt 34, a second branch and leaf removal conveyor belt 35, a bellows 36, a first fan 37, a second fan 38, and a transfer conveyor belt 39. The first branch and leaf removal drive assembly 31 is connected to the first branch and leaf removal conveyor belt 34 and is used to drive the first branch and leaf removal conveyor belt 34 to transfer fruits and vegetables along the first direction 70. The second branch and leaf removal drive assembly 32 is connected to the second branch and leaf removal conveyor belt 35 and is used to drive the second branch and leaf removal conveyor belt 36. The conveyor belt 35 transports fruits and vegetables along the first direction 70. The first leaf removal conveyor belt 34 and the second leaf removal conveyor belt 35 are both provided with first through holes (not shown in the figure). The air box 36 is installed on the frame and is located above the first leaf removal conveyor belt 34 and the second leaf removal conveyor belt 35. The first fan 37 and the second fan 38 are both installed on the frame. The first fan 37 and the second fan 38 are used to blow gas toward the first leaf removal conveyor belt 34 and the second leaf removal conveyor belt 35 respectively, so that the gas enters the air box 36 through the first through hole. The output end of the air box 36 is connected to the input end of the transfer conveyor belt 39. The transfer conveyor belt 39 is installed on the frame and is located below the first leaf removal conveyor belt 34 and the second leaf removal conveyor belt 35.

[0067] Specifically, fruits and vegetables move along a first direction 70 on the first leaf removal conveyor belt 34 and the second leaf removal conveyor belt 35. Gas blown by the first fan 37 and the second fan 38 is directed towards the fruits and vegetables through a first through-hole to separate the fruit stems from the fruit. The fruit stems enter the bellows 36, and under the influence of the wind, the fruit stems and leaves move towards the output end of the bellows 36 until they fall onto the transfer conveyor belt 39. The transfer conveyor belt 39 then carries the fruit stems and leaves away, thus completing the separation of the fruit from the fruit stems and leaves. Two fans, the first fan 37 and the second fan 38, are used, and they are located on opposite sides of the bellows 36 to ensure effective airflow to the first leaf removal conveyor belt 34 and the second leaf removal conveyor belt 35. Using one bellows 36 instead of multiple bellows 36 makes the structure more compact.

[0068] Both the first leaf and branch removal drive assembly 31 and the second leaf and branch removal drive assembly 32 include a motor and a rotating roller. The first leaf and branch removal conveyor belt 34 and the second leaf and branch removal conveyor belt 35 are respectively wound around a corresponding rotating roller. The motor drives the rotating roller to move, so that the first leaf and branch removal conveyor belt 34 and the second leaf and branch removal conveyor belt 35 transport fruits and vegetables along the first direction 70. Both the first leaf and branch removal conveyor belt 34 and the second leaf and branch removal conveyor belt 35 can be chain plates or conveyor belts.

[0069] In one embodiment, along the first direction 70, the position of the first branch removal conveyor belt 34 corresponds to the position of the first feeding conveyor belt 24, and the position of the second branch removal conveyor belt 35 corresponds to the position of the second feeding conveyor belt 25. Along the first direction 70, the width of the first branch removal conveyor belt 34 is the same as and remains unchanged with the width of the first feeding conveyor belt 24, and the width of the second branch removal conveyor belt 35 is the same as and remains unchanged with the width of the second feeding conveyor belt 25.

[0070] Specifically, the above structure ensures that the fruits and vegetables output from the first feeding conveyor belt 24 enter the first branch and leaf removal conveyor belt 34 along the first direction 70, and that the fruits and vegetables output from the second feeding conveyor belt 25 enter the second branch and leaf removal conveyor belt 35 along the first direction 70, thus maintaining a good fruit and vegetable conveying effect. The width of the first branch and leaf removal conveyor belt 34 is the same as and remains unchanged with the width of the first feeding conveyor belt 24, to ensure that the fruits and vegetables on the first feeding conveyor belt 24 and the first branch and leaf removal conveyor belt 34 move along the first direction 70.

[0071] The first leaf and branch removal conveyor belt 34 is positioned corresponding to the first feeding conveyor belt 24, and the second leaf and branch removal conveyor belt 35 is positioned corresponding to the second feeding conveyor belt 25, so that the driving force directions of the first leaf and branch removal drive assembly 31 and the first drive assembly 21 are consistent, and the driving force directions of the second leaf and branch removal drive assembly 32 and the second drive assembly 22 are consistent, reducing the number of transmission structures and making the fruit and vegetable conveying mechanism 100 more compact.

[0072] See Figure 1 , Figure 5 , Figure 8 and Figure 9 , Figure 8 yes Figure 1 Schematic diagram of the small and medium-sized fruit removal device; Figure 9 yes Figure 8 A top view of the small fruit removal device.

[0073] In one embodiment, the small fruit removal device 40 includes a first small fruit removal driving assembly 41, a second small fruit removal driving assembly 42, a third partition 43, a first small fruit removal conveyor belt 44, and a second small fruit removal conveyor belt 45. The first small fruit removal conveyor belt 44 and the second small fruit removal conveyor belt 45 are arranged side by side along a second direction 80. The third partition 43 is located between the first small fruit removal conveyor belt 44 and the second small fruit removal conveyor belt 45. The first small fruit removal driving assembly 41 is connected to the first small fruit removal... The conveyor belt 44 is used to drive the first small fruit removal conveyor belt 44 to transport fruits and vegetables along the first direction 70. The second small fruit removal drive assembly 42 is connected to the second small fruit removal conveyor belt 45 and is used to drive the second small fruit removal conveyor belt 45 to transport fruits and vegetables along the first direction 70. Along the first direction 70, the width of the first small fruit removal conveyor belt 44 and the width of the second small fruit removal conveyor belt 45 remain unchanged. The first small fruit removal conveyor belt 44 and the second small fruit removal conveyor belt 45 are both provided with a second through hole 46.

[0074] Specifically, fruits and vegetables flow out of the leaf and branch removal device 30 and into the small fruit removal device 40. The fruits and vegetables move along the first small fruit removal conveyor belt 44 and the second small fruit removal conveyor belt 45 in the first direction. Fruits and vegetables smaller than the second through hole 46 will be removed from the first small fruit removal conveyor belt 44 and the second small fruit removal conveyor belt 45 through the second through hole 46 to complete the small fruit removal operation.

[0075] Specifically, a first small fruit rejection drive assembly 41 and a second small fruit rejection drive assembly 42 are used to avoid the transmission effect of the first small fruit rejection conveyor belt 44 and the second small fruit rejection conveyor belt 45 being poor due to the excessive length and insufficient strength of the drive shaft of a single drive assembly.

[0076] In one embodiment, along the first direction 70, the position of the first branch and leaf removal transport belt 34 corresponds to the position of the first small fruit removal transport belt 44, and the position of the second branch and leaf removal transport belt 35 corresponds to the position of the second small fruit removal transport belt 45. Along the first direction 70, the width of the first branch and leaf removal transport belt 34 is the same as the width of the first small fruit removal transport belt 44 and remains unchanged, and the width of the second branch and leaf removal transport belt 35 is the same as the width of the second small fruit removal transport belt 45 and remains unchanged.

[0077] Specifically, the first leaf and branch removal conveyor belt 34 and the first small fruit removal conveyor belt 44 are both located on the same side of the third partition 43, while the second leaf and branch removal conveyor belt 35 and the second small fruit removal conveyor belt 45 are both located on the other side of the third partition 43. This ensures that the fruits and vegetables on the first leaf and branch removal conveyor belt 34 will fall into the first small fruit removal conveyor belt 44, and the fruits and vegetables on the second leaf and branch removal conveyor belt 35 will fall into the second small fruit removal conveyor belt 45. The positions of the first leaf and branch removal conveyor belt 34 and the first small fruit removal conveyor belt 44 correspond, and the positions of the second leaf and branch removal conveyor belt 35 and the second small fruit removal conveyor belt 45 correspond, so that the driving force directions of the first leaf and branch removal drive assembly 31 and the first small fruit removal drive assembly 41 are consistent, and the driving force directions of the second leaf and branch removal drive assembly 32 and the second small fruit removal drive assembly 42 are consistent, reducing the number of transmission structures and making the fruit and vegetable conveying mechanism 100 more compact.

[0078] Furthermore, the first branch and leaf removal transport belt 34, the second branch and leaf removal transport belt 35, the first small fruit removal transport belt 44, and the second small fruit removal transport belt 45 all have a rectangular structure with equal width from a top-view perspective, in order to simplify system integration.

[0079] See Figure 1 , Figure 2 , Figure 8 and Figure 10 , Figure 10 yes Figure 1 A side view of the arrangement of the branch and leaf removal device, the small fruit removal device, and the pre-arrangement device.

[0080] In one embodiment, the small fruit removal device 40 further includes a small fruit removal surface 47, on which fruits and vegetables are conveyed along a first direction 70; the pre-arrangement device 50 includes an arrangement surface 56, on which fruits and vegetables are conveyed along a first direction 70; the arrangement surface 56 is located below the small fruit removal surface 47; along the first direction 70, fruits and vegetables are conveyed from the small fruit removal surface 47 to the arrangement surface 56; the arrangement surface 56 includes a first part and a second part, the first part being located on a first pre-arrangement conveyor belt 511 and the second part being located on a second pre-arrangement conveyor belt 512.

[0081] Specifically, when fruits and vegetables are conveyed from the small fruit removal surface 47 to the arrangement surface 56, since the small fruit removal surface 47 is located above the arrangement surface 56, a fruit or vegetable will fall into the arrangement surface 56 in a parabolic manner. The fruit or vegetable that falls into the arrangement surface 56 first will continue to move along the first direction 70 under the action of the first pre-arrangement conveyor belt 511 and the second pre-arrangement conveyor belt 512. If another fruit or vegetable does not fall directly into the arrangement surface 56, it will remain on another fruit or vegetable located on the arrangement surface 56. Since the fruit or vegetable located on the arrangement surface 56 continues to move along the first direction 70, there will be relative movement between the two fruits or vegetables until the fruit or vegetable located above finally falls into the arrangement surface 56, so as to achieve the effect of preventing stacking.

[0082] The first part is located on the end face of the first pre-arranged conveyor belt 511 away from the frame 10, and the second part is located on the end face of the second pre-arranged conveyor belt 512 away from the frame 10.

[0083] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 In one embodiment, the frame 10 includes a first frame 11, a second frame 12, a third frame 13, and a fourth frame 14. A feeding device 20 is installed on the first frame 11, a branch and leaf removal device 30 is installed on the second frame 12, a small fruit removal device 40 is installed on the third frame 13, and a pre-arrangement device 50 is installed on the fourth frame 14. Any two adjacent first frames 11, second frames 12, third frames 13, and fourth frames 14 are detachably connected.

[0084] Specifically, different functional devices are installed on a corresponding frame to facilitate the installation and disassembly of different functional devices, as well as the packaging and loading / unloading of the overall fruit and vegetable conveying mechanism 100.

[0085] This utility model also provides a fruit and vegetable sorting machine, including the fruit and vegetable conveying mechanism 100 described in the above embodiment, and the fruit and vegetable sorting machine further includes a detection mechanism and a sorting mechanism.

[0086] The testing agency is used to test the fruits and vegetables transported by the fruit and vegetable transport agency 100, such as surface damage, fruit maturity, or fruit weight.

[0087] After testing, the fruits and vegetables are transported to a sorting facility, which sorts the tested fruits and vegetables and selects those that meet the standards to designated locations, thus completing the sorting process.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this utility model as described above.
