Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a rotating device, a sorting device, and post-harvest processing equipment for fruits and vegetables. Background Technology

[0002] Currently, fruits and vegetables are a type of food that people often consume. Fruits and vegetables include apples, pears, and tomatoes, among others. 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, fruits and vegetables need to be washed before sorting. After washing and sorting, the conveyor structure transports the fruits and vegetables to the gripping component, which then grabs them and transfers them into packaging boxes to complete the packing process. Generally, during the sorting process, post-harvest processing equipment needs to capture images of the fruits and vegetables to remove those with surface damage.

[0004] However, when the post-harvest processing equipment collects images of fruits and vegetables, the fruits and vegetables are placed on the supporting components, and part of the surface of the fruits and vegetables will come into contact with the supporting device, making it difficult for the image acquisition components to identify the surface of the fruits and vegetables in contact with the supporting device. Utility Model Content

[0005] The present invention aims to provide a rotating device, a sorting device, and a post-harvest processing equipment for fruits and vegetables, in order to solve the problem that in the prior art, part of the surface of fruits and vegetables comes into contact with the carrying device, making it difficult for the image acquisition component to identify the surface of the fruits and vegetables in contact with the carrying device.

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

[0007] A rotating device is provided, comprising:

[0008] The rotating module includes a support frame and a rotating drive assembly. The support frame has a limiting groove, and the rotating drive assembly includes a movable support surface that can support fruits and vegetables located in the limiting groove. When the support surface moves, it can drive the fruits and vegetables in the limiting groove to rotate.

[0009] With the above structure, when fruits and vegetables are located in the limiting groove, the support surface provides support to the lower surface of the fruits and vegetables in the limiting groove, and the side surface of the fruits and vegetables can abut against the groove wall. When the support surface moves, the support surface drives the fruits and vegetables to move in the limiting groove, and the groove wall abuts against the side of the fruits and vegetables, so that the fruits and vegetables can rotate in the limiting groove. In this way, the image acquisition module can take pictures of the fruits and vegetables in the limiting groove from multiple angles. A single image acquisition module can acquire images of the entire surface of the fruits and vegetables without moving.

[0010] In some embodiments, the rotation drive assembly includes a first drive component and a first conveyor belt, the first conveyor belt being connected to the first drive component, the first drive component being used to drive the first conveyor belt to move, and the support surface being the surface of the first conveyor belt facing the limiting groove.

[0011] With the above structure, friction will be generated between the support surface and the fruits and vegetables when the support surface moves relative to them. The first conveyor belt is made of flexible material, and the support surface is located on the upper surface of the first conveyor belt. The support surface is elastic, and the fruits and vegetables are not easily worn.

[0012] In some embodiments, the limiting groove is located above the support surface, and the central axis of the limiting groove is perpendicular to the support surface; one of the rotation drive assemblies includes at least two of the first conveyor belts;

[0013] In the same rotation drive assembly, all the first conveyor belts are arranged sequentially in the horizontal direction, the conveying directions of all the first conveyor belts are parallel to each other, and there is a gap between two adjacent first conveyor belts.

[0014] With the above structure, the central axis of the limiting groove is perpendicular to the support surface, and the same fruit and vegetable can be supported by at least two first conveyor belts. Both first conveyor belts can undergo elastic deformation when supporting the fruit and vegetable, and the fruit and vegetable can be partially embedded in the gap between the two adjacent first conveyor belts, so that the support surface can play a better supporting role for the fruit and vegetable in the limiting groove, and prevent the fruit and vegetable from falling off the support surface when rotating in the limiting groove.

[0015] In some embodiments, one of the rotation drive components includes two first conveyor belts, with the central axis of the limiting groove passing through the gap between the two first conveyor belts.

[0016] With the above structure, the central axis of the limiting groove passes through the gap between the two first conveyor belts. From a top-down angle, the center of gravity of the fruits and vegetables in the limiting groove can be located between the two first conveyor belts, so that the two first conveyor belts can support the fruits and vegetables in the corresponding limiting grooves more evenly.

[0017] In some embodiments, the rotation drive assembly further includes a transmission component;

[0018] In the same rotation drive assembly, the transmission component is a pulley connected between the first drive component and the first conveyor belt. The transmission component is inclined, and the first drive component drives all of the first conveyor belts to move synchronously through the transmission component.

[0019] With the above structure, in the same rotation drive assembly, one first drive component can simultaneously drive all the first conveyor belts to move synchronously; on the one hand, it simplifies the structure of the rotation drive assembly, and on the other hand, it improves the synchronization of all the first conveyor belts in the same rotation drive assembly.

[0020] In some embodiments, the number of the first driving components is the same as the number of the first conveyor belts, and the first driving components correspond one-to-one with the first conveyor belts, with each first driving component driving a corresponding first conveyor belt to move.

[0021] With the above structure, each first driving component can drive the corresponding first conveyor belt independently, so that different first conveyor belts in the same rotation driving assembly can have different movement speeds, so as to drive the fruits and vegetables in the limiting groove to have a rotational tendency with the axis of rotation perpendicular to the horizontal plane. The fruits and vegetables in the limiting groove can face the image acquisition module from all angles, and the image acquisition module can acquire images of the surface of the fruits and vegetables from more angles.

[0022] In some embodiments, the wall of the limiting groove includes an arc-shaped abutment surface that protrudes into the limiting groove and is used to abut against fruits and vegetables located in the limiting groove.

[0023] With the above structure, when fruits and vegetables rotate in the limiting groove, they will come into contact with the arc-shaped contact surface and generate friction. The arc-shaped contact surface can prevent the fruits and vegetables from being scratched when they rub against the surface of the fruits and vegetables.

[0024] This utility model also provides a sorting device, including the rotating device in any of the above embodiments, and further including an image acquisition module, which is used to acquire images of the surface of fruits and vegetables in the limiting groove.

[0025] With the above structure, the image acquisition module can acquire images of fruits and vegetables located in the limiting groove and transmit the image signals to the computer, which can then determine whether the surface condition of the fruits and vegetables is up to standard.

[0026] In some embodiments, the rotating device further includes a transmission module mounted on the support frame, the transmission module being used to transport fruits and vegetables into the limiting groove.

[0027] With the above structure, the rotating device is used to acquire images of the washed fruits and vegetables and remove those with surface defects. After the image acquisition module completes image acquisition of the fruits and vegetables in the limiting groove, the fruits and vegetables in the limiting groove are removed, and the transmission module transports the washed fruits and vegetables into the limiting groove to improve the working efficiency of the image acquisition module.

[0028] In some embodiments, the transmission module includes a second driving component and a second conveyor belt, the second conveyor belt being connected to the second driving component, the second driving component being used to drive the second conveyor belt to move, the support frame including a support platform, the limiting groove being formed in the support platform, and the top of the second conveyor belt being located above the support platform.

[0029] With the above structure, the top of the second conveyor belt is located above the support platform. When the fruits and vegetables on the second conveyor belt are transported to the corresponding limiting groove, they can slide into the corresponding limiting groove under the action of gravity, so that the second conveyor belt can more easily transport the fruits and vegetables to the corresponding limiting groove.

[0030] In some embodiments, the transmission module further includes a plurality of limiting protrusions, which protrude from the surface of the second conveyor belt. All the limiting protrusions are evenly arranged along the conveying direction of the second conveyor belt, and two adjacent limiting protrusions are used to limit a corresponding fruit or vegetable located on the second conveyor belt.

[0031] With the above structure, a fruit or vegetable is placed between two adjacent limiting protrusions. The distance between two adjacent limiting protrusions is equal. Then, during the process of the second driving component driving the second conveyor belt to move at a constant speed, the second conveyor belt moves a certain distance at fixed intervals, which can transport a fruit or vegetable into the corresponding limiting groove.

[0032] This utility model also provides a post-harvest processing device for fruits and vegetables, including the sorting device in any of the above embodiments.

[0033] Compared with existing technologies, when fruits and vegetables are located in the limiting groove, the support surface provides support to the lower surface of the fruits and vegetables in the limiting groove, and the side surface of the fruits and vegetables can abut against the groove wall. When the support surface moves, it drives the fruits and vegetables to move in the limiting groove, and the groove wall abuts against the side of the fruits and vegetables, so that the fruits and vegetables can rotate in the limiting groove. In this way, the image acquisition module can take pictures of the fruits and vegetables in the limiting groove from multiple angles, and a single image acquisition module can acquire images of the entire surface of the fruits and vegetables without moving.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] 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.

[0046] The following detailed description, in conjunction with all the accompanying drawings, describes in detail a rotating device 100, a sorting device 200, and a post-harvest processing device for fruits and vegetables provided in this application, through specific embodiments.

[0047] Please refer to Figure 1 , Figure 2 and Figure 3 One embodiment of this utility model discloses a sorting device 200, including a rotating device 100 and a data acquisition module 20. The rotating device 100 includes a rotating module 10; the rotating module 10 includes a support frame 12 and a rotating drive assembly 14. The support frame 12 has a limiting groove 1202. The rotating drive assembly 14 includes a movable support surface 1442, which can support fruits and vegetables located in the limiting groove 1202. When the support surface 1442 moves, it can drive the fruits and vegetables in the limiting groove 1202 to rotate. The image acquisition module 20 is installed on the support frame 12 and is used to acquire images of the surface of the fruits and vegetables in the limiting groove 1202.

[0048] With the above structure, when the fruits and vegetables are located in the limiting groove 1202, the supporting surface 1442 supports the lower surface of the fruits and vegetables in the limiting groove 1202, and the side surface of the fruits and vegetables can abut against the groove wall of the limiting groove 1202. When the supporting surface 1442 moves, the supporting surface 1442 drives the fruits and vegetables to move in the limiting groove 1202, and the groove wall of the limiting groove 1202 abuts against the side of the fruits and vegetables, so that the fruits and vegetables can rotate in the limiting groove 1202. Thus, the image acquisition module 20 can take pictures of the fruits and vegetables in the limiting groove 1202 from multiple angles. A single image acquisition module 20 can acquire images of the entire surface of the fruits and vegetables without moving.

[0049] Specifically, when the support surface 1442 moves, it can cause the fruits and vegetables in the limiting groove 1202 to abut against the groove wall of the limiting groove 1202, thereby causing the fruits and vegetables to rotate. In this embodiment, the support frame 12 can be a frame structure formed by splicing sheet metal. The support frame 12 can have multiple limiting grooves 1202, and all the limiting grooves 1202 are arranged in a row. The support frame 12 includes a support platform 122, which can be a sheet metal structure parallel to the horizontal plane. The limiting groove 1202 is a circular through groove opened on the limiting frame 12. The groove wall of the limiting groove 1202 can be fitted with a flexible washer to avoid damage when the fruits and vegetables abut against the groove wall of the limiting groove 1202.

[0050] Each rotation drive component 14 corresponds to a limiting groove 1202. The rotation drive component 14 can be a belt structure driven by a motor. The conveying direction of the belt structure can be perpendicular to the arrangement direction of all the limiting grooves 1202. The upper surface of the belt structure is a support surface 1442, which is parallel to the horizontal plane. The support surface 1442 is located below the corresponding limiting groove 1202. The distance between the support surface 1442 and the support platform 122 is adapted to the size of the fruits and vegetables so that the side surface of the fruits and vegetables on the support surface 1442 can abut against the groove wall of the corresponding limiting groove 1202.

[0051] The image acquisition module 20 can be a camera installed above the limiting slot 1202. Each limiting slot 1202 corresponds to one image acquisition module 20, and the image acquisition module 20 can be tilted. The image acquisition module 20 can be electrically connected to a computer. The image acquisition module 20 can transmit the acquired images of the fruit and vegetable surface to the computer, and the computer processes the images of the fruit and vegetable surface and determines whether there are defects on the surface of the fruit and vegetable.

[0052] In other embodiments, the limiting groove 1202 may also be of other shapes, such as ellipse; the rotation drive component 14 may also be of other structures, such as a motor-driven plate structure that can move below the limiting groove 1202; the rotation drive component 14 may also be a rotatable fruit cup for supporting fruits and vegetables; the support surface 1442 may also be curved; each limiting groove 1202 may also correspond to other numbers of image acquisition modules 20, such as two.

[0053] Please refer to Figure 4 In some embodiments, the rotation drive assembly 14 includes a first drive component 142 and a first conveyor belt 144. The first conveyor belt 144 is connected to the first drive component 142. The first drive component 142 is used to drive the first conveyor belt 144 to move. The support surface 1442 is the surface of the first conveyor belt 144 facing the limiting groove 1202.

[0054] With the above structure, when the support surface 1442 moves relative to the fruits and vegetables, friction will be generated between the support surface 1442 and the fruits and vegetables. The first conveyor belt 144 is made of flexible material, and the support surface 1442 is located on the upper surface of the first conveyor belt 144. The support surface 1442 is elastic, and the fruits and vegetables are not easily worn.

[0055] In addition, the first drive component 142 can control the movement speed of the first conveyor belt 144, thereby adjusting the rotation speed of the fruits and vegetables located in the limiting groove 1202, so that the image acquisition module 20 can more accurately acquire images of various parts of the fruit and vegetable surface.

[0056] Specifically, in this embodiment, the first drive component 142 can be a motor, the first conveyor belt 144 can be made of flexible materials such as leather, the conveying direction of the first conveyor belt 144 is parallel to the horizontal plane, and each rotation drive component 14 can include two first conveyor belts 144.

[0057] In other embodiments, the first conveyor belt 144 may also be made of other materials, such as rubber; each rotation drive assembly 14 may also include other numbers of first conveyor belts 144, such as one or three; the support surface 1442 may also be inclined relative to the horizontal plane.

[0058] In some embodiments, the limiting groove 1202 is located above the support surface 1442, and the central axis of the limiting groove 1202 is perpendicular to the support surface 1442; a rotation drive assembly 14 includes at least two first conveyor belts 144.

[0059] In the same rotation drive assembly 14, all the first conveyor belts 144 are arranged sequentially in the horizontal direction, and the conveying directions of all the first conveyor belts 144 are parallel to each other, with a gap between two adjacent first conveyor belts 144.

[0060] With the above structure, the central axis of the limiting groove 1202 is perpendicular to the support surface 1442, and the same fruit and vegetable can be supported by at least two first conveyor belts 144. Both first conveyor belts 144 can undergo elastic deformation when supporting the fruit and vegetable, and the fruit and vegetable can be partially embedded in the gap between the two adjacent first conveyor belts 144, so that the support surface 1442 can provide better support for the fruit and vegetable in the limiting groove 1202, and prevent the fruit and vegetable from falling off the support surface 1442 when rotating in the limiting groove 1202.

[0061] Specifically, the gap between two adjacent first conveyor belts 144 is smaller than the size of the fruits and vegetables to prevent them from falling off between the two adjacent first conveyor belts 144.

[0062] In some embodiments, a rotation drive assembly 14 includes at least two first conveyor belts 144, with the central axis of the limiting groove 1202 passing through the gap between the two first conveyor belts 144.

[0063] With the above structure, the central axis of the limiting groove 1202 passes through the gap between the two first conveyor belts 144. From a top-down angle, the center of gravity of the fruits and vegetables in the limiting groove 1202 can be located between the two first conveyor belts 144, so that the two first conveyor belts 144 can support the fruits and vegetables in the corresponding limiting grooves 1202 more evenly.

[0064] Specifically, the limiting groove 1202 is a circular through groove, and from a top view angle, the center of the limiting groove 1202 is located between two adjacent first conveyor belts 144.

[0065] In some embodiments, the rotation drive assembly 14 further includes a transmission component 146; in the same rotation drive assembly 14, the transmission component 146 is a pulley connected between the first drive component 142 and the first conveyor belt 144, the transmission component 146 is inclined, and the first drive component 142 drives all the first conveyor belts 144 to move synchronously through the transmission component 146.

[0066] With the above structure, in the same rotation drive assembly 14, one first drive component 142 can simultaneously drive all the first conveyor belts 144 to move synchronously; on the one hand, it simplifies the structure of the rotation drive assembly 14, and on the other hand, it improves the synchronization of all the first conveyor belts 144 in the same rotation drive assembly 14.

[0067] Specifically, in this embodiment, the transmission component 146 can be an inclined pulley structure; in the same rotation drive assembly 14, the lower end of the transmission component 146 is connected to the first drive component 142, and the upper end of the transmission component 146 and the ends of all the first conveyor belts 144 are connected to the same rotation shaft, so that the first drive component 142 can drive all the first conveyor belts 144 to move synchronously through the transmission component 146.

[0068] In some other embodiments, the number of first drive components 142 is the same as the number of first conveyor belts 144, and the first drive components 142 correspond one-to-one with the first conveyor belts 144. Each first drive component 142 is used to drive the corresponding first conveyor belt 144 to move.

[0069] With the above structure, each first driving component 142 can drive the corresponding first conveyor belt 144 independently, so that different first conveyor belts 144 in the same rotation driving assembly 14 can have different movement speeds, so as to drive the fruits and vegetables in the limiting groove 1202 to have a rotational tendency with the axis of rotation perpendicular to the horizontal plane. The fruits and vegetables in the limiting groove 1202 can face the image acquisition module 20 from all angles, and the image acquisition module 20 can acquire images of the surface of the fruits and vegetables from more angles.

[0070] Specifically, in the same rotation drive assembly 14, there can be two first conveyor belts 144 and two first drive components 142. From a top view, the two first conveyor belts 144 are located between the two first drive components 142. For example, the first drive component 142 corresponding to one of the first conveyor belts 144 is located at one end of the rotation drive assembly 14, and the first drive component 142 corresponding to the other first conveyor belt 144 is located at the other opposite end of the rotation drive assembly 14.

[0071] Please refer to Figure 5In some embodiments, the groove wall of the limiting groove 1202 includes an arc-shaped abutment surface 124, which protrudes into the limiting groove 1202 and is used to abut against fruits and vegetables located in the limiting groove 1202.

[0072] With the above structure, when the fruits and vegetables rotate in the limiting groove 1202, they will come into contact with the arc-shaped contact surface 124 and generate friction. The arc-shaped contact surface 124 can prevent the fruits and vegetables from being scratched when it rubs against the surface of the fruits and vegetables.

[0073] Specifically, the cross-section of the arc-shaped contact surface 124 is similar to a semi-circle.

[0074] Please refer to Figure 6 and Figure 7 In some embodiments, the sorting device 200 further includes a transmission module 30, which is used to transport fruits and vegetables into the limiting groove 1202.

[0075] With the above structure, the sorting device 200 is used to acquire images of the washed fruits and vegetables and remove fruits and vegetables with surface defects. Whenever the image acquisition module 20 completes image acquisition of the fruits and vegetables in the limiting groove 1202, the fruits and vegetables in the limiting groove 1202 are removed, and the transmission module 30 transports the washed fruits and vegetables into the limiting groove 1202 to improve the working efficiency of the image acquisition module 20.

[0076] Specifically, in this embodiment, the transmission module 30 can be installed on the support frame 12. The transmission module 30 can be a motor-driven pulley structure. Each limiting groove 1202 corresponds to one transmission module 30. The transmission module 30 is used to transport fruits and vegetables into the corresponding limiting groove 1202.

[0077] In other embodiments, the transmission module 30 may also be other structures, such as a motor-driven robotic arm or a cylinder-driven suction cup structure.

[0078] In some embodiments, the transmission module 30 includes a second driving component 32 and a second conveyor belt 34. The second conveyor belt 34 is connected to the second driving component 32, and the second driving component 32 is used to drive the second conveyor belt 34 to move. The support frame 12 includes a support platform 122, a limiting groove 1202 is formed in the support platform 122, and the top of the second conveyor belt 34 is located above the support platform 122.

[0079] With the above structure, the top of the second conveyor belt 34 is located above the support platform 122. When the fruits and vegetables on the second conveyor belt 34 are transported to the corresponding limiting groove 1202, they can slide into the corresponding limiting groove 1202 under the action of gravity, so that the second conveyor belt 34 can more easily transport the fruits and vegetables to the corresponding limiting groove 1202.

[0080] Specifically, in this embodiment, the conveying direction of the second conveyor belt 34 can be parallel to the horizontal plane, one end of the second conveyor belt 34 is located on one side of the corresponding limiting groove 1202, and the other opposite end of the second conveyor belt 34 is connected to the second driving component 32.

[0081] In other embodiments, the second conveyor belt 34 may also be inclined, with the end of the second conveyor belt 34 closer to the corresponding limiting groove 1202 being higher and the end of the second conveyor belt 34 away from the corresponding limiting groove 1202 being lower.

[0082] In some embodiments, the transmission module 30 further includes a plurality of limiting protrusions 36, which protrude from the surface of the second conveyor belt 34. All the limiting protrusions 36 are evenly arranged along the conveying direction of the second conveyor belt 34, and two adjacent limiting protrusions 36 are used to limit a corresponding fruit or vegetable located on the second conveyor belt 34.

[0083] With the above structure, a fruit or vegetable is placed between two adjacent limiting protrusions 36. The distance between two adjacent limiting protrusions 36 is equal. Then, during the process of the second driving component 32 driving the second conveyor belt 34 to move at a constant speed, the second conveyor belt 34 moves a certain distance at fixed intervals, which can transport a fruit or vegetable into the corresponding limiting groove 1202.

[0084] Adjusting the speed of the second conveyor belt 34 allows the fruits and vegetables closest to the limiting groove 1202 to be transported into the limiting groove 1202, while the image acquisition module 20 acquires images of the fruit and vegetable surfaces to automate the rotating device 100.

[0085] Specifically, in this embodiment, the limiting protrusion 36 can be made of metal material. The limiting protrusion 36 has a hollow strip structure. The central axis of the limiting protrusion 36 is perpendicular to the conveying direction of the second conveyor belt 34. The side surface of the limiting protrusion 36 is arc-shaped to avoid scratching fruits and vegetables when they come into contact with the limiting protrusion 36.

[0086] In other embodiments, the limiting protrusion 36 may also be made of other materials, such as flexible materials like rubber; the limiting protrusion 36 may also be a solid structure.

[0087] This utility model also provides a post-harvest processing device for fruits and vegetables, including the sorting device 200 in any of the above embodiments. The post-harvest processing device for fruits and vegetables may include a washing module for washing fruits and vegetables, a weighing module for weighing fruits and vegetables, and a packing module for placing the sorted fruits and vegetables into packaging boxes; the post-harvest processing device for fruits and vegetables can wash the harvested fruits and vegetables, classify the fruits and vegetables according to their weight, and finally pack the fruits and vegetables into boxes.

[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 different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail; although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
