Description

Technical Field

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

[0002] Currently, fruits and vegetables are a type of food that people often consume. Fruits and vegetables include citrus fruits, cherries, apples, pears, tomatoes, and pineapples. After ripening, fruits and vegetables need to be harvested and then transported to factories for sorting and processing to facilitate subsequent packaging and sales.

[0003] In related technologies, fruit and vegetable sorting devices may include fruit and vegetable conveying mechanisms, which may include conveying chains. The conveying chains may carry fruit cups, which are used to move fruits and vegetables in the fruit and vegetable sorting devices. One end of the chain is fitted onto the drive wheel, and the other end is fitted onto the driven wheel. The chain is relatively heavy, and in some cases, the lower side of the chain needs to be supported by auxiliary wheels. The lower end of the chain near the drive wheel is inclined.

[0004] However, the chain may vibrate due to high tension during movement, causing the drive wheel to wobble, which may lead to misalignment of the drive wheel and drive components. Utility Model Content

[0005] The present invention aims to provide a chain support component, a fruit and vegetable conveying mechanism, and a fruit and vegetable sorting device to solve the technical problem in the prior art that the chain may vibrate due to large tension during movement, causing the drive wheel to shake and resulting in the drive wheel and drive component to deviate.

[0006] The technical problem solved by this utility model embodiment is addressed by the following technical solution:

[0007] One embodiment of this utility model provides a chain support assembly, comprising:

[0008] A supporting beam extends in a direction parallel to the horizontal plane, and the supporting beam includes a supporting inclined wall;

[0009] A support plate component is provided, which is inclined and fixed to the inclined support wall. The extension direction of the support beam is perpendicular to the extension direction of the support plate component. The distance between the upper end of the support beam and the support plate component is greater than the distance between the lower end of the support beam and the support plate component.

[0010] A support frame is mounted on the support plate component and is located at the upper end of the support plate component.

[0011] With the above structure, the support beam and support frame can be fixed to the frame of the fruit and vegetable conveying mechanism, so that the support beam and support frame can support the support plate component. The fruit and vegetable conveying mechanism can include a conveyor chain and a drive wheel, with a portion of the conveyor chain inclined downwards near the drive wheel. The upper surface of the support plate component allows the inclined portion of the conveyor chain to rest against it. The support plate component supports the conveyor chain, reducing the degree of swaying of the conveyor chain as it moves towards the drive wheel, reducing the pressure on the drive wheel, improving the stability of the drive wheel, and reducing the possibility of the drive wheel deviating.

[0012] In addition, the supporting beam includes a supporting inclined wall, and the supporting plate component is fixed to the supporting inclined wall; the supporting inclined wall and the supporting plate component have a larger contact area, so that the supporting inclined wall can provide better support for the supporting plate component, thereby increasing the maximum pressure that the supporting plate component can withstand.

[0013] In some embodiments, the chain support assembly further includes a first mounting bracket and a second mounting bracket, which are respectively mounted at opposite ends of the support beam; the support plate component is located between the first mounting bracket and the second mounting bracket in the extending direction of the support beam.

[0014] With the above structure, the first mounting bracket and the second mounting bracket are respectively installed at opposite ends of the supporting beam; both the first mounting bracket and the second mounting bracket can support the supporting beam to improve its stability. The supporting beam, the first mounting bracket, and the second mounting bracket can be pre-assembled, then the first mounting bracket and the second mounting bracket are fixed to the frame of the fruit and vegetable conveying mechanism, and finally the support plate component is fixed to the supporting inclined wall.

[0015] In some embodiments, the chain support assembly further includes a first locking member and a second locking member, one end of the support slope is rotatably connected to the first mounting bracket, and the other opposite end of the support slope is rotatably connected to the second mounting bracket;

[0016] The first locking member is installed between the supporting inclined wall and the first mounting bracket, and the first locking member is used to fix or release the first mounting bracket and the supporting inclined wall; the second locking member is installed between the supporting inclined wall and the second mounting bracket, and the second locking member is used to fix or release the second mounting bracket and the supporting inclined wall.

[0017] With the above structure, when the inclination of the conveyor chain is inconsistent with the inclination of the support plate component, the first locking member can be released from the first mounting bracket and the support inclined wall, and the second locking member can be released from the second mounting bracket and the support inclined wall at the same time. Then, the support beam is rotated relative to the first mounting bracket and the second mounting bracket to an appropriate position, and the first locking member is locked to the first mounting bracket and the support inclined wall, and the second locking member is locked to the second mounting bracket and the support inclined wall at the same time. This allows the inclination of the support plate component to be matched with the inclination of the conveyor chain.

[0018] In some embodiments, the support beam further includes a connecting plate connected to the side of the support inclined wall facing the higher end of the support plate component, the connecting plate being inclined relative to the support inclined wall.

[0019] With the above structure, the connecting plate is connected to the side of the support inclined wall facing the higher end of the support plate component; the connecting plate is farther away from the rotation axis of the support inclined wall, and the user can apply a smaller axial force to the connecting plate to drive the support inclined wall to rotate.

[0020] In some embodiments, the support plate component includes:

[0021] The main body is inclined and fixed to the supporting inclined wall;

[0022] A flexible support strip is installed on the surface of the main body facing away from the support beam, and the extension direction of the flexible support strip is parallel to the extension direction of the main body;

[0023] The side blocking wall consists of two side blocking walls, which are respectively connected to opposite sides of the main body. The side blocking walls extend in a direction parallel to the extension direction of the main body. The side blocking walls are inclined relative to the main body, with the lower end of the side blocking wall connected to the main body and the higher end of the side blocking wall facing away from the flexible support strip.

[0024] With the above structure, the flexible support strip is installed on the surface of the main body facing away from the support beam. The flexible support strip can support the conveyor chain. The flexible support strip contacts the conveyor chain and undergoes elastic deformation to increase the contact area between the conveyor chain and the flexible support strip, so as to avoid wear during the movement of the conveyor chain.

[0025] In addition, two side blocking walls are connected to opposite sides of the main body. The side blocking walls can limit the conveyor chain to prevent it from detaching from the main body, so that the support plate component can support the conveyor chain more stably.

[0026] In some embodiments, the support plate component further includes a first transition plate, which is mounted on the upper side of the main body. The angle between the first transition plate and the horizontal plane is smaller than the angle between the main body and the horizontal plane, and the upper end of the flexible support strip is located on the first transition plate.

[0027] With the above structure, after the conveyor chain detaches from the upper end of the main body, the side of the first transition plate facing the main body can continue to support the conveyor chain, so as to avoid friction or collision between the conveyor chain and the end of the main body, thereby avoiding damage to the conveyor chain or the main body.

[0028] In addition, the angle between the first transition plate and the horizontal plane is smaller than the angle between the main body and the horizontal plane, and the angle between the part of the conveyor chain on the main body and the horizontal plane is equal to the angle between the main body and the horizontal plane. It can be deduced that the angle between the first transition plate and the horizontal plane is smaller than the angle between the part of the conveyor chain on the main body and the horizontal plane. The end of the first transition plate facing the main body contacts the conveyor chain. It can be deduced that the end of the first transition plate facing away from the main body can have a gap with the conveyor chain. The conveyor chain can disengage from the first transition plate through the middle of the first transition plate, avoiding friction or collision between the end of the conveyor chain and the end of the first transition plate.

[0029] The upper end of the flexible support bar is located on the first transition plate, so that the part of the conveyor chain located at the first transition plate can also contact the flexible support bar, further reducing the wear of the conveyor chain.

[0030] In some embodiments, the support plate component further includes a second transition plate, which is mounted on the lower side of the main body. The angle between the second transition plate and the horizontal plane is greater than the angle between the main body and the horizontal plane. The end of the second transition plate facing away from the main body is lower than the end of the second transition plate facing the main body. The lower end of the flexible support strip is located on the second transition plate.

[0031] With the above structure, the angle between the second transition plate and the horizontal plane is greater than the angle between the main body and the horizontal plane, and the angle between the part of the conveyor chain on the main body and the horizontal plane is equal to the angle between the main body and the horizontal plane. It can be deduced that the angle between the second transition plate and the horizontal plane is greater than the angle between the part of the conveyor chain on the main body and the horizontal plane. The upper side of the second transition plate is in contact with the conveyor chain, so it can be deduced that there is a gap between the lower side of the second transition plate and the conveyor chain. During the process of the conveyor chain moving towards the lower side of the main body, it can first contact the middle part of the second transition plate to avoid the conveyor chain colliding with the lower side of the main body and reduce the wear degree of the conveyor chain and the main body.

[0032] In addition, the lower end of the flexible support bar is located on the second transition plate, so that the part of the conveyor chain located on the second transition plate can also contact the flexible support bar, further reducing the wear of the conveyor chain.

[0033] In some embodiments, there are two flexible support strips, which are located on opposite sides of the main body; the main body has a clearance groove located between the two flexible support strips.

[0034] With the above structure, the fruit and vegetable conveying mechanism in this embodiment may include two conveying chains, and a fruit cup for carrying fruits and vegetables may be set between the two conveying chains; each flexible support bar can support one conveying chain.

[0035] In addition, the main body is provided with a clearance groove, which is located between two flexible support bars. The conveyor chain may be covered with debris such as fruit and vegetable branches and leaves, so the conveyor chain and chain support components need to be cleaned regularly. The clearance groove allows the cleaning fluid to flow out, making the chain support components easier to clean.

[0036] Another embodiment of this utility model provides a fruit and vegetable conveying mechanism, including the chain support assembly of any of the above embodiments, and further including a drive assembly, a conveying chain, a drive wheel, a driven wheel, and an auxiliary wheel. The conveying chain is sleeved on the drive wheel, the driven wheel, and the auxiliary wheel. The drive wheel and the driven wheel are at the same height, and the auxiliary wheel is located below the drive wheel. The drive assembly drives the conveying chain to move via the drive wheel, and the portion of the conveying chain located between the drive wheel and the auxiliary wheel abuts against the support inclined wall.

[0037] Another embodiment of this utility model provides a fruit and vegetable sorting device, including the fruit and vegetable conveying mechanism in the above embodiment.

[0038] Compared to existing technologies, the support beam and support frame can be fixed to the frame of the fruit and vegetable conveying mechanism, allowing them to support the support plate component. The fruit and vegetable conveying mechanism includes a conveyor chain and a drive wheel, with a portion of the conveyor chain inclined downwards near the drive wheel. The upper surface of the support plate component provides support for the inclined portion of the conveyor chain, reducing the degree of swaying as the conveyor chain moves towards the drive wheel, decreasing the pressure on the drive wheel, improving its stability, and reducing the possibility of drive wheel deviation.

[0039] In addition, the supporting beam includes a supporting inclined wall, and the supporting plate component is fixed to the supporting inclined wall; the supporting inclined wall and the supporting plate component have a larger contact area, so that the supporting inclined wall can provide better support for the supporting plate component, thereby increasing the maximum pressure that the supporting plate component can withstand.

[0050] The following detailed description, in conjunction with all the accompanying drawings, of a chain support assembly 100, a fruit and vegetable conveying mechanism 1000, and a fruit and vegetable sorting device provided in this application, will be provided through specific embodiments.

[0051] Please refer to Figures 1 to 3 An embodiment of this utility model provides a fruit and vegetable conveying mechanism 1000, including a chain support assembly 100, a drive assembly, a conveying chain 200, a drive wheel 300, a driven wheel, and an auxiliary wheel 400. The conveying chain 200 is sleeved on the drive wheel 300, the driven wheel, and the auxiliary wheel 400. The drive wheel 300 and the driven wheel are at the same height, and the auxiliary wheel 400 is located below the drive wheel 300. The drive assembly drives the conveying chain 200 to move via the drive wheel 300. The portion of the conveying chain 200 located between the drive wheel 300 and the auxiliary wheel 400 abuts against the chain support assembly 100.

[0052] In some embodiments, the chain support assembly 100 includes a support beam 10, a support plate component 20, and a support frame 30; the extension direction of the support beam 10 is parallel to the horizontal plane, and the support beam 10 includes a support inclined wall 12; the support plate component 20 is inclined and fixed to the support inclined wall 12, and the extension direction of the support beam 10 is perpendicular to the extension direction of the support plate component 20; the distance between the upper end of the support beam 10 and the support plate component 20 is greater than the distance between the lower end of the support beam 10 and the support plate component 20; the support frame 30 is mounted on the support plate component 20 and is located at the upper end of the support plate component 20.

[0053] With the above structure, the support beam 10 and the support frame 30 can be fixed to the frame of the fruit and vegetable conveying mechanism 1000, so that the support beam 10 and the support frame 30 can support the support plate component 20; the portion of the conveyor chain 200 near the drive wheel 300 is inclined downwards. The upper surface of the support plate component 20 can be abutted by the inclined portion of the conveyor chain 200, and the support plate component 20 supports the conveyor chain 200, reducing the degree of swaying of the conveyor chain 200 as it moves toward the drive wheel 300, reducing the pressure on the drive wheel 300, improving the stability of the drive wheel 300, and reducing the possibility of the drive wheel 300 deviating.

[0054] In addition, the support beam 10 includes a support inclined wall 12, and the support plate component 20 is fixed to the support inclined wall 12. The support inclined wall 12 and the support plate component 20 have a larger contact area, so the support inclined wall 12 can provide better support for the support plate component 20, thereby increasing the maximum pressure that the support plate component 20 can withstand.

[0055] Specifically, in this embodiment, the support beam 10 may include a sheet metal structure with a bend, one section of the support beam 10 is inclined relative to the horizontal plane to form a support inclined wall 12, and the other section of the support beam 10 may be parallel to the horizontal plane; both ends of the support beam 10 may be fixed to the frame of the fruit and vegetable conveying mechanism 1000 by mounting brackets.

[0056] The support plate component 20 may include a steel plate with a notch in the center. The support plate component 20 may be a flat plate structure. The support plate component 20 may be fixed to the support inclined wall 12 by screws or bolts. In the extension direction of the support beam 10, the support plate component 20 may be located in the middle of the support beam 10.

[0057] The support frame 30 may include a plate-shaped metal structure that is perpendicular to the horizontal plane. The two sides of the plate-shaped metal may be provided with folded edges. The support plate component 20 may be fixed to the support frame 30 by means of threaded connection or welding. The support frame 30 may be connected to the frame of the fruit and vegetable conveying mechanism 1000 by means of threaded connectors.

[0058] In other embodiments, the supporting beam 10 may also include other structures, such as hollow steel bars; the supporting plate component 20 may also include other structures, such as the supporting plate component 20 having an overall arc-shaped plate structure; the supporting frame 30 may also include other structures, such as a structure formed by splicing steel bars; the supporting plate component 20 may also be connected to the supporting frame 30 in other ways, such as by snap-fit.

[0059] In some embodiments, the chain support assembly 100 further includes a first mounting bracket 40 and a second mounting bracket 50, which are respectively mounted on opposite ends of the support beam 10; and a support plate component 20 is located between the first mounting bracket 40 and the second mounting bracket 50 in the extending direction of the support beam 10.

[0060] With the above structure, the first mounting bracket 40 and the second mounting bracket 50 are respectively installed at opposite ends of the supporting beam 10; both the first mounting bracket 40 and the second mounting bracket 50 can support the supporting beam 10 to improve its stability. The supporting beam 10, the first mounting bracket 40 and the second mounting bracket 50 can be pre-assembled, then the first mounting bracket 40 and the second mounting bracket 50 are fixed to the frame of the fruit and vegetable conveying mechanism 1000, and finally the support plate component 20 is fixed to the supporting inclined wall 12.

[0061] Specifically, in this embodiment, the first mounting bracket 40 and the second mounting bracket 50 may have the same structure; the first mounting bracket 40 may include a hollow block structure formed by bending sheet metal, and the first mounting bracket 40 and the support beam 10 may be connected to each other by threaded connectors, the support beam 10 may have threaded holes, the first mounting bracket 40 may have waist-shaped holes, and the threaded connectors are sequentially inserted into the waist-shaped holes and the threaded holes.

[0062] In other embodiments, the first mounting frame 40 may also include other structures, such as a frame structure formed by splicing steel bars; the first mounting frame 40 and the supporting beam 10 may also be connected in other ways, such as by snap-fit.

[0063] In some embodiments, the chain support assembly 100 further includes a first locking member and a second locking member, one end of the support inclined wall 12 is rotatably connected to the first mounting bracket 40, and the other opposite end of the support inclined wall 12 is rotatably connected to the second mounting bracket 50.

[0064] The first locking member is installed between the supporting inclined wall 12 and the first mounting bracket 40, and the first locking member is used to fix or release the first mounting bracket 40 and the supporting inclined wall 12; the second locking member is installed between the supporting inclined wall 12 and the second mounting bracket 50, and the second locking member is used to fix or release the second mounting bracket 50 and the supporting inclined wall 12.

[0065] With the above structure, when the inclination of the conveyor chain 200 is inconsistent with the inclination of the support plate component 20, the first locking member can be released from the first mounting bracket 40 and the support inclined wall 12, and the second locking member can be released from the second mounting bracket 50 and the support inclined wall 12. Then, the support beam 10 is rotated relative to the first mounting bracket 40 and the second mounting bracket 50 to an appropriate position, and the first locking member is locked to the first mounting bracket 40 and the support inclined wall 12, while the second locking member is locked to the second mounting bracket 50 and the support inclined wall 12. This allows the inclination of the support plate component 20 to be adapted to the inclination of the conveyor chain 200.

[0066] Specifically, in this embodiment, one side of the supporting inclined wall 12 abuts against the side of the first mounting bracket 40, and the other side of the supporting inclined wall 12 facing away from the first mounting bracket 40 abuts against the side of the second mounting bracket 50. Both sides of the supporting inclined wall 12 are provided with threaded holes 1202, and the first mounting bracket 40 may be provided with a waist-shaped clearance hole 402. Both the first locking member and the second locking member may include threaded connectors, such as screws or bolts, which may pass through the waist-shaped clearance hole 402 on the first mounting bracket 40 and the threaded hole 1202 on the supporting inclined wall 12. After both the first locking member and the second locking member are loosened, the user can apply an axial force to the supporting beam 10 to cause the supporting inclined wall 12 to rotate relative to the first mounting bracket 40 and the second mounting bracket 50.

[0067] In other embodiments, the supporting beam 10 may also include a rotating shaft, the supporting inclined wall 12 is fixed to the rotating shaft, and the two ends of the rotating shaft are respectively rotatably connected to the first mounting bracket 40 and the second mounting bracket 50.

[0068] In some embodiments, the support beam 10 further includes a connecting plate 14, which is connected to the side of the support inclined wall 12 facing the higher end of the support plate component 20, and the connecting plate 14 is inclined relative to the support inclined wall 12.

[0069] With the above structure, the connecting plate 14 is connected to the side of the supporting inclined wall 12 facing the higher end of the supporting plate component 20; the connecting plate 14 is farther away from the rotation axis of the supporting inclined wall 12, and the user can apply a smaller axial force to the connecting plate 14 to drive the supporting inclined wall 12 to rotate.

[0070] Specifically, in this embodiment, the connecting plate 14 and the supporting inclined wall 12 can be integrally formed. The connecting plate 14 can be formed by bending one side of the supporting inclined wall 12. Both the connecting plate 14 and the supporting inclined wall 12 can include a steel flat plate structure. In the extension direction of the supporting beam 10, the length of the connecting plate 14 is equal to the length of the supporting inclined wall 12. The two ends of the supporting inclined wall 12 can be bent to form a plate-like structure perpendicular to the horizontal plane for connecting the first mounting bracket 40 and the second mounting bracket 50.

[0071] In other embodiments, the connecting plate 14 may also include other structures, such as an arc-shaped plate structure.

[0072] Please refer to Figure 3 and Figure 4 In some embodiments, the support plate component 20 includes a main body 22, a flexible support strip 24, and a side blocking wall 26; the main body 22 is inclined and fixed to the support inclined wall 12; the flexible support strip 24 is installed on the surface of the main body 22 facing away from the support beam 10, and the extension direction of the flexible support strip 24 is parallel to the extension direction of the main body 22.

[0073] There are two side blocking walls 26, which are respectively connected to the opposite sides of the main body 22. The extension direction of the side blocking walls 26 is parallel to the extension direction of the main body 22. The side blocking walls 26 are inclined relative to the main body 22. The lower end of the side blocking wall 26 is connected to the main body 22, and the higher end of the side blocking wall 26 faces away from the flexible support strip 24.

[0074] With the above structure, the flexible support bar 24 is installed on the surface of the main body 22 facing away from the support beam 10. The flexible support bar 24 can support the conveyor chain 200. The flexible support bar 24 contacts the conveyor chain 200 and undergoes elastic deformation to increase the contact area between the conveyor chain 200 and the flexible support bar 24, so as to avoid wear during the movement of the conveyor chain 200.

[0075] In addition, the two side blocking walls 26 are respectively connected to the opposite sides of the main body 22. The side blocking walls 26 can limit the conveyor chain 200 to prevent the conveyor chain 200 from detaching from the main body 22, so that the support plate component 20 can support the conveyor chain 200 more stably.

[0076] Specifically, in this embodiment, the main body 22 may include a rectangular steel plate structure, and the number of flexible support strips 24 may be two. The two flexible support strips 24 may be located on both sides of the main body 22 respectively. The flexible support strips 24 may be made of materials such as silicone, and the cross-section of the flexible support strips 24 may be convex.

[0077] The side barrier 26 may include a rectangular plate of metal. The side barrier 26 may be formed by bending one side of the main body 22. The angle between the side barrier 26 and the main body 22 is an obtuse angle, so that the higher end of the side barrier 26 faces away from the flexible support strip 24.

[0078] In other embodiments, the number of flexible support bars 24 may be other, such as one or three; the cross-section of the flexible support bar 24 may also be other shapes, such as rectangular or semi-circular.

[0079] In some embodiments, the support plate component 20 further includes a first transition plate 28, which is mounted on the upper side of the main body 22. The angle between the first transition plate 28 and the horizontal plane is smaller than the angle between the main body 22 and the horizontal plane, and the upper end of the flexible support strip 24 is located on the first transition plate 28.

[0080] With the above structure, after the conveyor chain 200 is separated from the upper end of the main body 22, the side of the first transition plate 28 facing the main body 22 can continue to support the conveyor chain 200, so as to avoid friction or collision between the conveyor chain 200 and the end of the main body 22, thereby avoiding damage to the conveyor chain 200 or the main body 22.

[0081] Furthermore, the angle between the first transition plate 28 and the horizontal plane is smaller than the angle between the main body 22 and the horizontal plane, and the angle between the portion of the conveyor chain 200 located on the main body 22 and the horizontal plane is equal to the angle between the main body 22 and the horizontal plane. It can be deduced that the angle between the first transition plate 28 and the horizontal plane is smaller than the angle between the portion of the conveyor chain 200 located on the main body 22 and the horizontal plane. The end of the first transition plate 28 facing the main body 22 contacts the conveyor chain 200. It can be deduced that the end of the first transition plate 28 facing away from the main body 22 can have a gap with the conveyor chain 200, and the conveyor chain 200 can disengage from the first transition plate 28 through the middle of the first transition plate 28, thus avoiding friction or collision between the end of the conveyor chain 200 and the end of the first transition plate 28.

[0082] The upper end of the flexible support bar 24 is located on the first transition plate 28, so that the part of the conveyor chain 200 located at the first transition plate 28 can also contact the flexible support bar 24, further reducing the wear of the conveyor chain 200.

[0083] Specifically, in this embodiment, the first transition plate 28 may include a flat plate structure arranged parallel to the horizontal plane, and the width of the first transition plate 28 may be equal to the width of the main body 22.

[0084] In other embodiments, the end of the first transition plate 28 facing away from the main body 22 may also be tilted upward or downward.

[0085] In some embodiments, the support plate component 20 further includes a second transition plate 29, which is mounted on the lower side of the main body 22. The angle between the second transition plate 29 and the horizontal plane is greater than the angle between the main body 22 and the horizontal plane.

The lower end of the flexible support strip 24 is located on the second transition plate 29.

[0086] With the above structure, the angle between the second transition plate 29 and the horizontal plane is greater than the angle between the main body 22 and the horizontal plane. The angle between the part of the conveyor chain 200 located on the main body 22 and the horizontal plane is equal to the angle between the main body 22 and the horizontal plane. It can be deduced that the angle between the second transition plate 29 and the horizontal plane is greater than the angle between the part of the conveyor chain 200 located on the main body 22 and the horizontal plane. The upper side of the second transition plate 29 is in contact with the conveyor chain 200. It can be deduced that there is a gap between the lower side of the second transition plate 29 and the conveyor chain 200. During the process of the conveyor chain 200 moving towards the lower side of the main body, it can first contact the middle part of the second transition plate 29 to avoid the conveyor chain 200 colliding with the lower side of the main body and reduce the wear degree of the conveyor chain 200 and the main body 22.

[0087] In addition, the lower end of the flexible support bar 24 is located on the second transition plate 29, so that the part of the conveyor chain 200 located at the second transition plate 29 can also contact the flexible support bar 24, further reducing the wear of the conveyor chain 200.

[0088] Specifically, in this embodiment, the second transition plate 29 may include a rectangular steel plate, and the second transition plate 29 may be formed by bending the lower side of the main body 22 downwards. The width of the second transition plate 29 may be smaller than the width of the main body 22.

[0089] In other embodiments, the second transition plate 29 may also include other structures, such as a semi-circular steel plate.

[0090] In some embodiments, there are two flexible support bars 24, which are located on opposite sides of the main body 22. The main body 22 is provided with a clearance groove 2202, which is located between the two flexible support bars 24.

[0091] With the above structure, the fruit and vegetable conveying mechanism 1000 in this embodiment may include two conveying chains 200, and a fruit cup for carrying fruits and vegetables may be provided between the two conveying chains 200; each flexible support bar 24 can support one conveying chain 200.

[0092] In addition, the main body 22 is provided with a clearance groove 2202, which is located between two flexible support bars 24. The conveyor chain 200 may be covered with debris such as fruit and vegetable branches and leaves, so the conveyor chain 200 and the chain support assembly 100 need to be cleaned regularly. The clearance groove 2202 allows the cleaning liquid to flow out, making the chain support assembly 100 easier to clean.

[0093] Specifically, the clearance groove 2202 can be a rectangular groove that can penetrate the upper and lower surfaces of the main body 22; the two flexible support strips 24 can be attached to the two sides of the clearance groove 2202 respectively.

[0094] Another embodiment of this utility model provides a fruit and vegetable sorting device, including the fruit and vegetable conveying mechanism 1000 in the above embodiment; the fruit and vegetable sorting device may further include a fruit and vegetable sorting mechanism and an output mechanism, the fruit and vegetable conveying mechanism 1000 is used to drive fruits and vegetables through the fruit and vegetable sorting mechanism; the fruit and vegetable sorting mechanism is used to collect information of fruits and vegetables and to classify fruits and vegetables according to the information, each level of fruits and vegetables can correspond to an output mechanism, and the information of fruits and vegetables may include weight information or surface image information; when the fruit and vegetable conveying mechanism 1000 drives the fruits and vegetables to the corresponding output mechanism, the fruits and vegetables can enter the fruit and vegetable output mechanism from the fruit and vegetable conveying mechanism 1000.
