Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable sorting, in particular to a conveying device. Background Art

[0002] At present, with the market demand, fruits and vegetables need to be classified according to the quality or sugar content of individual fruits before packaging.

[0003] In the related art, the classification of fruits and vegetables is generally completed by a sorting machine, which includes a transmission mechanism and a weighing mechanism. The transmission mechanism is used to drive the fruits and vegetables to the weighing mechanism. When the total mass of the fruits and vegetables on the weighing mechanism reaches a preset mass, the fruits and vegetables on the weighing mechanism are sent away for packaging.

[0004] The transmission mechanism generally includes a conveyor belt driven by a motor. In order to improve the conveying efficiency of fruits and vegetables, the width of the conveyor belt is generally large. There are more fruits and vegetables on the conveyor belt, and multiple fruits and vegetables on the conveyor belt will be driven to the weighing mechanism; when the total weight of the fruits and vegetables on the weighing mechanism is about to reach the preset weight, multiple fruits and vegetables are driven to the weighing mechanism at the same time, which can easily cause the total weight of the fruits and vegetables on the weighing mechanism to be far greater than the preset weight, ultimately resulting in a large weighing error. Utility Model Content

[0005] The embodiment of the utility model aims to provide a conveying device to solve the technical problem of large quality error of fruits and vegetables when weighing fruits and vegetables in the prior art.

[0006] The utility model embodiment solves its technical problems by adopting the following technical solutions:

[0007] A transmission device is provided, comprising:

[0008] Mounting table;

[0009] A first transmission mechanism, the first transmission mechanism is installed on the installation platform, the first transmission mechanism comprises a first driving assembly and a first conveyor belt, the first driving assembly is used to drive the first conveyor belt to move;

[0010] a second transmission mechanism, the second transmission mechanism is installed on the installation platform, the second transmission mechanism comprises a second driving assembly and a second conveyor belt, the second driving assembly is used to drive the second conveyor belt to move, the first conveyor belt and the second conveyor belt are arranged in parallel, and the width of the first conveyor belt is smaller than the width of the second conveyor belt;

[0011] A weighing mechanism, the weighing mechanism is installed on the mounting platform, and the weighing mechanism is placed at the output end of the first conveyor belt and the output end of the second conveyor belt;

[0012] A control device, wherein the control device is electrically connected to the weighing mechanism, and the control device can independently control the opening and closing of the first drive assembly and the second drive assembly.

[0013] Through the above structure, the width of the first conveyor belt is smaller than that of the second conveyor belt, and it can be inferred that the number of fruits and vegetables on the same width of the first conveyor belt is small. Then, when the mass on the weighing mechanism is close to the required value, the first conveyor belt alone transports fruits and vegetables to the weighing mechanism, and the number of fruits and vegetables input into the weighing mechanism at the same time is reduced, so that after weighing, the total weight of fruits and vegetables on the weighing mechanism is closer to the first preset mass, and finally the error in the weighing process is reduced.

[0014] In some embodiments, the conveying device further comprises a third conveying mechanism, the third conveying mechanism is mounted on the mounting platform, the third conveying mechanism comprises a third driving assembly and a third conveyor belt, and the output end of the third conveyor belt is connected to the input ends of the first conveyor belt and the second conveyor belt;

[0015] The first conveyor belt and the second conveyor belt are arranged horizontally, the third conveyor belt is arranged obliquely relative to the first conveyor belt and the second conveyor belt, and the height of the output end of the third conveyor belt is higher than the height of the input end of the third conveyor belt.

[0016] Through the above structure, fruits and vegetables need to be washed before entering the conveying device, and a large amount of washing liquid will enter the conveying device together with the fruits and vegetables; the third conveyor belt is inclined relative to the first conveyor belt and the second conveyor belt, so that the third conveyor belt can drive the fruits and vegetables to move from the input end to the output end, and the washing liquid cannot flow to the output end of the third conveyor belt under the action of gravity, so that the fruits and vegetables can be driven to the weighing mechanism by the first conveyor belt or the second conveyor belt, and the washing liquid cannot be driven to the weighing mechanism by the first conveyor belt or the second conveyor belt, thereby improving the accuracy of the weighing mechanism when weighing.

[0017] In some embodiments, the height of the output end of the third conveyor belt is greater than the heights of the input ends of the first conveyor belt and the second conveyor belt.

[0018] Through the above structure, when the fruits and vegetables move to the output end of the third conveyor belt, they can fall into the input end of the first conveyor belt or the input end of the second conveyor belt under the action of gravity, so that the fruits and vegetables will not be stuck between the output end of the third conveyor belt and the input and output end of the first conveyor belt, or between the output end of the third conveyor belt and the input and output end of the second conveyor belt, thereby reducing the possibility of blockage of the conveying device.

[0019] In some embodiments, the conveying device also includes a guide member, which is installed on the mounting platform and is inclined relative to the first conveyor belt and the second conveyor belt; one end of the guide member is connected to the output end of the third conveyor belt, and the other end is connected to the input end of the first conveyor belt and the input end of the second conveyor belt.

[0020] Through the above structure, when fruits and vegetables enter the input end of the first conveyor belt or the input end of the second conveyor belt from the output end of the third conveyor belt, the guide member can support and guide the fruits and vegetables, and then the guide member can buffer the fruits and vegetables, thereby reducing the possibility of fruits and vegetables being damaged.

[0021] In some embodiments, the conveying device further comprises a columnar member, the mounting platform comprises two vertical side walls, the first conveyor belt and the second conveyor belt are both placed between the two vertical side walls; one end of the columnar member is connected to one of the vertical side walls, the other end of the columnar member is connected to the other vertical side wall, the columnar member is perpendicular to the vertical side walls, and the columnar member is located between the guide member and the third conveyor belt;

[0022] The guide member includes a guide inclined surface, a guide vertical surface and two connecting plates. The guide inclined surface is inclined relative to the second conveyor belt, the guide vertical surface is perpendicular to the second conveyor belt, the end of the guide inclined surface facing away from the third conveyor belt is connected to the end of the guide vertical surface facing away from the third conveyor belt, the two connecting plates are respectively connected to both sides of the guide inclined surface, and each of the connecting plates is connected to one of the vertical side walls.

[0023] Through the above structure, the columnar member and the rotating shaft at the output end of the third conveyor belt jointly clamp the third conveyor belt to prevent the third conveyor belt from loosening; in addition, the columnar member can prevent the roots of fruits and vegetables from being caught between the guide member and the third conveyor belt.

[0024] In addition, the guide slope can guide and support the fruits and vegetables, and the guide vertical surface can cover the gap between the guide slope and the second conveyor belt and the first conveyor belt, thereby preventing the roots of the fruits and vegetables from being caught between the guide slope and the first conveyor belt, or between the guide slope and the second conveyor belt. The connection plate cooperates with the vertical side wall, making it easier to install the guide member and the mounting platform.

[0025] In some embodiments, the first transmission mechanism includes one first conveyor belt, the second transmission mechanism includes two second conveyor belts, the second driving assembly is used to drive the two second conveyor belts to move synchronously; and the first conveyor belt is located between the two second conveyor belts.

[0026] Through the above structure, the width of the first conveyor belt is narrower, and thus the number of fruits and vegetables located in the same width direction of the first conveyor belt is smaller. When the first conveyor belt is placed between two second conveyor belts, the first conveyor belt is not directly close to the mounting table. There is a preset distance between the first conveyor belt and the mounting table, and thus the fruits and vegetables on the first conveyor belt will not contact the mounting table but will be attached to the mounting table, ultimately reducing the possibility of the mounting table blocking the first conveyor belt.

[0027] In some embodiments, the conveying device also includes a partition installed on the mounting platform, each of the partitions is placed on the side of a corresponding second conveyor belt away from the first conveyor belt, and the partition covers the gap between the mounting platform and a corresponding second conveyor belt.

[0028] Through the above structure, the partition covers the gap between the mounting platform and a corresponding second conveyor belt, thereby preventing fruits and vegetables from being drawn into the gap between the mounting platform and a corresponding second conveyor belt; at the same time, it also reduces the possibility that the fruits and vegetables come into contact with the mounting platform and become stationary relative to the mounting platform under the action of static friction.

[0029] In some embodiments, the mounting platform includes two vertical side walls, and the first conveyor belt and the second conveyor belt are placed between the two vertical side walls; the partition is a plate-like structure, and the partition is inclined relative to the first conveyor belt and the second conveyor belt, one side of the partition is installed on the corresponding vertical side wall, and the other side of the partition is in contact with a corresponding second conveyor belt, and the partition covers the gap between the corresponding vertical side wall and the corresponding second conveyor belt.

[0030] Through the above structure, when the partition is a plate-like structure, the manufacturing cost of the partition is low, and the partition is inclined relative to the first conveyor belt and the second conveyor belt, so that when the fruits and vegetables move to the input end of the second conveyor belt through the guide member, the partition can guide the fruits and vegetables close to the vertical side wall, so that the fruits and vegetables move in the direction away from the vertical side wall.

[0031] In some embodiments, the partition includes a vertical plate and an inclined plate, the inclined plate is inclined relative to the first conveyor belt and the second conveyor belt, one side of the inclined plate is connected to one side of the vertical plate, and the other side of the inclined plate is in contact with a corresponding second conveyor belt, the vertical plate is installed on the corresponding vertical side wall, and the inclined plate covers the gap between the corresponding vertical side wall and the corresponding second conveyor belt.

[0032] Through the above structure, the vertical plate is easier to be installed with the vertical side wall, thereby reducing the installation cost between the partition and the vertical side wall.

[0033] In some embodiments, the conveying device also includes a fourth conveying mechanism, which includes a fourth drive assembly and a fourth conveyor belt. The conveying direction of the fourth conveyor belt is opposite to that of the first conveyor belt, and the fourth conveyor belt is placed above one side of the first conveyor belt.

[0034] Through the above structure, when the user finds unqualified or damaged fruits and vegetables on the first conveyor belt or the second conveyor belt, they can be taken out and placed on the fourth conveyor belt, and the fourth conveyor belt will drive the unqualified fruits and vegetables to the recycling mechanism, thereby preventing the unqualified fruits and vegetables from being transported to the weighing device.

[0035] Compared with the prior art, the width of the first conveyor belt is smaller than that of the second conveyor belt, and it can be inferred that the number of fruits and vegetables on the same width of the first conveyor belt is small; when the mass of fruits and vegetables on the weighing mechanism is small, the control device controls the first drive assembly and the second drive assembly to be turned on at the same time, so that the fruits and vegetables are input into the weighing mechanism at the fastest rate; when the mass of fruits and vegetables on the weighing mechanism is close to the required value, the control device controls the second drive assembly to be turned off, and the first drive assembly continues to be turned on, so that only a small amount of fruits and vegetables are input into the weighing mechanism; when the mass of fruits and vegetables on the weighing mechanism is greater than or equal to the required value, the weighing mechanism controls the first drive assembly and the second drive assembly to be turned off, and completes one weighing. When the mass of fruits and vegetables on the weighing mechanism is close to the required value, the number of fruits and vegetables input into the weighing mechanism at the same time is reduced, so that after the weighing is completed, the total weight of fruits and vegetables on the weighing mechanism is closer to the required value, and finally reduces the error in the weighing process.

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.

[0047] The following describes in detail a conveying device 100 provided in an embodiment of the present application through a specific embodiment in combination with all the drawings in the specification.

[0048] Please refer to Figure 1 and Figure 2In one embodiment of the utility model, a conveying device 100 is disclosed, including a mounting platform 10, a first conveying mechanism 20, a second conveying mechanism 30, a weighing mechanism 40 and a control mechanism; the first conveying mechanism 20 is mounted on the mounting platform 10, the first conveying mechanism 20 includes a first driving component 22 and a first conveyor belt 24, the first driving component 22 is used to drive the first conveyor belt 24 to move; the second conveying mechanism 30 is mounted on the mounting platform 10, the second conveying mechanism 30 includes a second driving component 32 and a second conveyor belt 34, the second driving component 32 is used to drive the second conveyor belt 34 to move, the first conveyor belt 24 and the second conveyor belt 34 are arranged in parallel, and the width of the first conveyor belt 24 is smaller than the width of the second conveyor belt 34; the weighing mechanism 40 is mounted on the mounting platform 10, the weighing mechanism 40 is placed at the output end of the first conveyor belt 24 and the output end of the second conveyor belt 34; the control device is electrically connected to the weighing mechanism 40, and the control device can independently control the opening and closing of the first driving component 22 and the second driving component 32.

[0049] Through the above structure, the width of the first conveyor belt 24 is smaller than the width of the second conveyor belt 34, and it can be inferred that the number of fruits and vegetables located in the same width direction of the first conveyor belt 24 is small. Then, when the weight on the weighing mechanism 40 is close to the required value, the control device can control the first conveyor belt 24 to transport fruits and vegetables to the weighing mechanism 40 alone, thereby reducing the number of fruits and vegetables input into the weighing mechanism 40 at the same time, so that after weighing, the total weight of fruits and vegetables on the weighing mechanism 40 is closer to the required value, and finally reducing the error in the weighing process.

[0050] A first preset mass and a second preset mass can be set for the weighing mechanism 40, wherein the first preset mass is greater than the second preset mass, wherein the first preset mass is the required mass for a single weighing of the weighing mechanism 40, and the second preset mass is close to the first preset mass, for example, the second preset mass can be ninety percent of the first preset mass.

[0051] When the mass of fruits and vegetables on the weighing mechanism 40 is less than the second preset mass, the control device controls the first drive assembly 22 and the second drive assembly 32 to be turned on at the same time, so that the fruits and vegetables are input into the weighing mechanism 40 at the fastest rate; when the mass of fruits and vegetables on the weighing mechanism 40 is greater than the second preset mass and less than the first preset mass, the control device controls the second drive assembly 32 to be turned off, and the first drive assembly 22 continues to be turned on, so that a small amount of fruits and vegetables are input into the weighing mechanism 40; when the mass of fruits and vegetables on the weighing mechanism 40 is greater than or equal to the first preset mass, the weighing mechanism 40 controls the first drive assembly 22 to be turned off, and one weighing is completed.

[0052] Specifically, in the present embodiment, the mounting platform 10 is a frame structure; the first conveyor belt 24 and the second conveyor belt 34 are belts arranged in parallel, and the lengths of the first conveyor belt 24 and the second conveyor belt 34 are equal; both ends of the first conveyor belt 24 are rotatably connected to the mounting platform 10 through a rotating shaft, and both ends of the second conveyor belt 34 are also rotatably connected to the mounting platform 10 through a rotating shaft. The number of the first conveyor belt 24 is one, and the number of the second conveyor belts 34 is two, and the first conveyor belt 24 is located between the two second conveyor belts 34.

[0053] The first drive component 22 is a drive motor, and the second drive component 32 is a clutch. The first drive component 22 is connected to a rotating shaft of the first conveyor belt 24, and the second drive component 32 is arranged on the rotating shaft of the first conveyor belt 24 and the second conveyor belt 34; when the second drive component 32 connects the rotating shaft of the first conveyor belt 24 with the rotating shaft of the second conveyor belt 34, the first drive component 22 drives the first conveyor belt 24 and the second conveyor belt 34 to move simultaneously; when the second drive component 32 separates the rotating shaft of the first conveyor belt 24 from the rotating shaft of the second conveyor belt 34, the first drive component 22 drives the first conveyor belt 24 to move alone.

[0054] In other embodiments, the first drive assembly 22 may also be a motor, and the first drive assembly 22 and the second drive assembly 32 are independent of each other; the lengths of the first conveyor belt 24 and the second conveyor belt 34 may also be different, the first conveyor belt 24 and the second conveyor belt 34 may be aligned toward one end of the weighing mechanism 40, and the first conveyor belt 24 and the second conveyor belt 34 may be staggered at one end away from the weighing mechanism 40, so that the rotation axes of the first conveyor belt 24 and the second conveyor belt 34 at one end away from the weighing mechanism 40 are not coaxially arranged, the first drive assembly 22 is connected to the rotation axis of the first conveyor belt 24 away from the weighing mechanism 40, and the second drive assembly 32 is connected to the rotation axis of the second conveyor belt 34 away from the weighing mechanism 40. The number of the first conveyor belts 24 and the second conveyor belts 34 may be set to other numbers according to actual needs.

[0055] The weighing mechanism 40 is an electronic scale, and the control device is a computer or a circuit board connected to the computer; the weighing mechanism 40 can transmit the quality information of the fruits and vegetables placed on the weighing mechanism 40 to the control device.

[0056] In some embodiments, the conveying device 100 also includes a third conveying mechanism 50, which is installed on the mounting platform 10. The third conveying mechanism 50 includes a third drive assembly 52 and a third conveyor belt 54, and the output end of the third conveyor belt 54 is connected to the input end of the first conveyor belt 24 and the second conveyor belt 34.

[0057] The first conveyor belt 24 and the second conveyor belt 34 are arranged horizontally, the third conveyor belt 54 is arranged obliquely relative to the first conveyor belt 24 and the second conveyor belt 34 , and the height of the output end of the third conveyor belt 54 is higher than the height of the input end of the third conveyor belt 54 .

[0058] Through the above structure, fruits and vegetables need to be cleaned before entering the conveying device 100, and a large amount of cleaning liquid will enter the conveying device 100 together with the fruits and vegetables; the third conveyor belt 54 is inclined relative to the first conveyor belt 24 and the second conveyor belt 34, and the height of the output end of the third conveyor belt 54 is higher than the height of the input end of the third conveyor belt 54, so that the third conveyor belt 54 can drive the fruits and vegetables to move from the input end to the output end, and the cleaning liquid cannot flow to the output end of the third conveyor belt 54 under the action of gravity, so that the fruits and vegetables can be driven to the weighing mechanism 40 by the first conveyor belt 24 or the second conveyor belt 34, and the cleaning liquid cannot be driven to the weighing mechanism 40 by the first conveyor belt 24 or the second conveyor belt 34, thereby improving the accuracy of the weighing mechanism 40 when weighing.

[0059] Specifically, the third drive assembly 52 is a normally-on motor, the third conveyor belt 54 is a belt, the third drive assembly 52 is connected to the rotating shaft at the input end of the third conveyor belt 54, and the width of the third conveyor belt 54 is the sum of the widths of all the first conveyor belts 24 and all the second conveyor belts 34. The inclination angle of the third conveyor belt 54 relative to the first conveyor belt 24 and the second conveyor belt 34 is greater than 10° and less than 30°.

[0060] In some embodiments, the height of the output end of the third conveyor belt 54 is greater than the height of the input end of the first conveyor belt 24 and the input end of the second conveyor belt 34 .

[0061] Through the above structure, when the fruits and vegetables move to the output end of the third conveyor belt 54, they can fall into the input end of the first conveyor belt 24 or the input end of the second conveyor belt 34 under the action of gravity, so that the fruits and vegetables will not be stuck between the output end of the third conveyor belt 54 and the input and output end of the first conveyor belt 24, or between the output end of the third conveyor belt 54 and the input and output end of the second conveyor belt 34, thereby reducing the possibility of blockage of the conveying device 100.

[0062] Specifically, the conveying directions of the first conveyor belt 24 and the third conveyor belt 54 are the same; from the perspective of the central axis direction of the rotating shaft of the first conveyor belt 24, the height of the input end of the third conveyor belt 54 is smaller than the height of the input end of the first conveyor belt 24 and the input end of the second conveyor belt 34.

[0063] In some embodiments, the conveying device 100 also includes a guide member 60, which is installed on the mounting platform 10, and the guide member 60 is inclined relative to the first conveyor belt 24 and the second conveyor belt 34; one end of the guide member 60 is connected to the output end of the third conveyor belt 54, and the other end is connected to the input end of the first conveyor belt 24 and the input end of the second conveyor belt 34.

[0064] Through the above structure, when fruits and vegetables enter the input end of the first conveyor belt 24 or the input end of the second conveyor belt 34 from the output end of the third conveyor belt 54, the guide member 60 can support and guide the fruits and vegetables, and then the guide member 60 can buffer the fruits and vegetables, reducing the possibility of the fruits and vegetables being damaged.

[0065] Specifically, in this embodiment, the guide member 60 is a rectangular block structure, and chamfers are provided at both ends of the side of the guide member 60 away from the third conveyor belt 54. In other embodiments, the guide member 60 can also be other structures, such as a block structure with an arc-shaped end face; in the direction from the third conveyor belt 54 to the first conveyor belt 24, the inclination of the end face of the guide member 60 relative to the first conveyor belt 24 gradually decreases; so that the fruits and vegetables can be further buffered when passing through the guide member 60.

[0066] Please refer to Figure 3 and Figure 4 In some embodiments, the conveying device 100 also includes a columnar member 90, the mounting platform 10 includes two vertical side walls 12, and the first conveyor belt 24 and the second conveyor belt 34 are both placed between the two vertical side walls 12; one end of the columnar member 90 is connected to one vertical side wall 12, and the other end of the columnar member 90 is connected to the other vertical side wall 12, the columnar member 90 is perpendicular to the vertical side wall 12, and the columnar member 90 is located between the guide member 60 and the third conveyor belt 54.

[0067] The guide member 60 includes a guide inclined surface 62, a guide vertical surface 64 and two connecting plates 66. The guide inclined surface 62 is inclined relative to the second conveyor belt 34, the guide vertical surface 64 is perpendicular to the second conveyor belt 34, and the end of the guide inclined surface 62 facing away from the third conveyor belt 54 is connected to the end of the guide vertical surface 64 facing away from the third conveyor belt 54. The two connecting plates 66 are respectively connected to both sides of the guide inclined surface 62, and each connecting plate 66 is connected to a vertical side wall 12.

[0068] Through the above structure, the columnar member 90 and the rotating shaft at the output end of the third conveyor belt 54 jointly clamp the third conveyor belt 54 to prevent the third conveyor belt 54 from loosening; in addition, the columnar member 90 can prevent the roots of fruits and vegetables from being caught between the guide member 60 and the third conveyor belt 54.

[0069] In addition, the guide slope 62 can guide and support the fruits and vegetables, and the guide vertical surface 64 can cover the gap between the guide slope 62 and the second conveyor belt 34 and the first conveyor belt 24, thereby preventing the roots of the fruits and vegetables from being caught between the guide slope 62 and the first conveyor belt 24, or between the guide slope 62 and the second conveyor belt 34. The connection plate 66 cooperates with the vertical side wall 12, making it easier to install the guide member 60 and the mounting platform 10.

[0070] Specifically, in this embodiment, the columnar member 90 is a cylinder; in other embodiments, the columnar member 90 may also be other structures, such as a cuboid. The guide member 60 is made of sheet metal material by bending, the guide inclined surface 62 and the guide vertical surface 64 are both flat plates, the connecting plate 66 is an "L"-shaped structure, a section of the connecting plate 66 is in contact with the vertical side wall 12, and the end of the connecting plate 66 away from the guide inclined surface 62 is connected to the upper end of the vertical side wall 12 through a threaded connector.

[0071] In some embodiments, the first transmission mechanism 20 includes one first conveyor belt 24 , the second transmission mechanism 30 includes two second conveyor belts 34 , the second drive assembly 32 is used to drive the two second conveyor belts 34 to move synchronously; the first conveyor belt 24 is located between the two second conveyor belts 34 .

[0072] Through the above structure, the width of the first conveyor belt 24 is narrow, and thus the number of fruits and vegetables located in the same width direction of the first conveyor belt 24 is small. When the first conveyor belt 24 is placed between the two second conveyor belts 34, the first conveyor belt 24 is not directly close to the mounting platform 10. There is a preset distance between the first conveyor belt 24 and the mounting platform 10, and thus the fruits and vegetables on the first conveyor belt 24 will not contact the mounting platform 10 but will be attached to the mounting platform 10, ultimately reducing the possibility of the mounting platform 10 blocking the first conveyor belt 24.

[0073] Specifically, in this embodiment, the widths of the two second conveyor belts 34 are the same, and the input ends of the two second conveyor belts 34 share a rotating shaft, and the output ends of the two second conveyor belts 34 also share a rotating shaft. In other embodiments, the widths of the two second conveyor belts 34 may also be different.

[0074] In some embodiments, the conveying device 100 also includes a partition 70, which is installed on the mounting platform 10, and each partition 70 is placed on the side of a corresponding second conveyor belt 34 away from the first conveyor belt 24, and the partition 70 covers the gap between the mounting platform 10 and a corresponding second conveyor belt 34.

[0075] Through the above structure, the partition 70 covers the gap between the mounting platform 10 and a corresponding second conveyor belt 34, thereby preventing fruits and vegetables from being drawn into the gap between the mounting platform 10 and a corresponding second conveyor belt 34; at the same time, it also reduces the possibility that the fruits and vegetables come into contact with the mounting platform 10 and become stationary relative to the mounting platform 10 under the action of static friction.

[0076] Specifically, in the present embodiment, the separator 70 is roughly a strip-shaped plate structure with an “L”-shaped cross-section; in other embodiments, the separator 70 may also be other structures, such as a brush structure, with the bristles facing the second conveyor belt 34 .

[0077] Please refer to Figure 5 and Figure 6 In some embodiments, the mounting platform 10 includes two vertical side walls 12, and the first conveyor belt 24 and the second conveyor belt 34 are both placed between the two vertical side walls 12; the partition 70 is a plate-like structure, and the partition 70 is inclined relative to the first conveyor belt 24 and the second conveyor belt 34. One side of the partition 70 is installed on the corresponding vertical side wall 12, and the other side of the partition 70 is in contact with a corresponding second conveyor belt 34. The partition 70 covers the gap between the corresponding vertical side wall 12 and the corresponding second conveyor belt 34.

[0078] Through the above structure, when the partition 70 is a plate-like structure, the manufacturing cost of the partition 70 is low, and the partition 70 is inclined relative to the first conveyor belt 24 and the second conveyor belt 34, so that when the fruits and vegetables move to the input end of the second conveyor belt 34 through the guide member 60, the partition 70 can guide the fruits and vegetables close to the vertical side wall 12, so that the fruits and vegetables move in the direction away from the vertical side wall 12.

[0079] Specifically, the length of the separator 70 is adapted to the length of the second conveyor belt 34, one end of the separator 70 is in contact with the guide member 60, and the other end is located at the output end of the corresponding second conveyor belt 34. In this embodiment, the angle between the separator 70 and the second conveyor belt 34 is 45°; in other embodiments, the angle between the separator 70 and the second conveyor belt 34 can also be other angles, such as 60°.

[0080] In some embodiments, the partition 70 includes a vertical plate 72 and an inclined plate 74. The inclined plate 74 is inclined relative to the first conveyor belt 24 and the second conveyor belt 34. One side of the inclined plate 74 is connected to one side of the vertical plate 72, and the other side of the inclined plate 74 is in contact with a corresponding second conveyor belt 34. The vertical plate 72 is installed on the corresponding vertical side wall 12, and the inclined plate 74 covers the gap between the corresponding vertical side wall 12 and the corresponding second conveyor belt 34.

[0081] Through the above structure, the vertical plate 72 is easier to be installed with the vertical side wall 12, thereby reducing the installation cost between the partition 70 and the vertical side wall 12.

[0082] Specifically, the vertical plate 72 and the inclined plate 74 are both rectangular plate structures, the vertical plate 72 and the end surface of the vertical side wall 12 facing the second conveyor belt 34 are in contact with each other, and a folding structure 76 is provided on the side of the inclined plate 74 away from the vertical side wall 12, and the folding structure 76 makes the side of the inclined plate 74 away from the vertical side wall 12 smoother, reducing the possibility of damage to the fruits and vegetables when the inclined plate 74 collides with the fruits and vegetables. In this embodiment, the vertical plate 72 is installed on the vertical side wall 12 by bolts or screws; in other embodiments, the vertical plate 72 can also be installed on the vertical side wall 12 by other means, such as welding.

[0083] Please refer to Figure 1 In some embodiments, the conveying device 100 also includes a fourth conveying mechanism 80, the fourth conveying mechanism 80 includes a fourth driving assembly 82 and a fourth conveyor belt 84, the conveying direction of the fourth conveyor belt 84 is opposite to that of the first conveyor belt 24, and the fourth conveyor belt 84 is placed above one side of the first conveyor belt 24.

[0084] Through the above structure, when the user finds that there are unqualified or damaged fruits and vegetables on the first conveyor belt 24 or the second conveyor belt 34, they can be taken out and placed on the fourth conveyor belt 84. The fourth conveyor belt 84 drives the unqualified fruits and vegetables to the recycling mechanism, thereby preventing the unqualified fruits and vegetables from being transported to the weighing device.

[0085] Specifically, the fourth conveyor belt 84 is a belt, and the fourth drive assembly 82 is a motor installed on the mounting platform 10 ; the length of the fourth conveyor belt 84 is equal to the sum of the length of the first conveyor belt 24 and the length of the third conveyor belt 54 .

[0086] In some embodiments, the number of the weighing mechanisms 40 is at least two, and each weighing mechanism 40 corresponds to at least one first transmission mechanism 20 and one first transmission mechanism 30 .

[0087] Through the above structure, the multiple weighing mechanisms 40 can weigh the fruits and vegetables independently, thereby improving the transportation efficiency of the fruits and vegetables.

[0088] Specifically, in this embodiment, the number of weighing mechanisms 40 is two, the number of fourth transmission mechanisms 80 is one, and the fourth transmission mechanism 80 is located between the two weighing mechanisms 40. In other embodiments, the number of weighing mechanisms 40 can also be other numbers, such as three, and correspondingly, the number of fourth transmission mechanisms 80 is two, and one fourth transmission mechanism 80 is provided between two adjacent weighing mechanisms 40.
