Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a fruit and vegetable packing 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, and tomatoes. 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 packing mechanisms. After the fruit and vegetable sorting device sorts the fruits and vegetables, the fruit and vegetable packing mechanism can pack fruits and vegetables of the same grade into boxes. Generally, the fruit and vegetable packing mechanism may include a robotic arm or a suction cup so that the fruit and vegetable packing mechanism can pick up the fruits and vegetables and put them into the fruit box.

[0004] However, the number of fruits and vegetables that a robotic arm or suction cup can grasp at a time is limited, and the fruit and vegetable packing mechanism needs to do so multiple times to fill a fruit box, resulting in a slow packing speed. Utility Model Content

[0005] The present invention aims to provide a fruit and vegetable packing mechanism and a fruit and vegetable sorting device to solve the technical problem that the existing fruit and vegetable packing mechanism requires multiple attempts to fill a fruit box with fruits and vegetables, resulting in a slow packing speed.

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

[0007] A fruit and vegetable packing mechanism is provided, comprising:

[0008] frame;

[0009] The loading and unloading assembly is mounted on the frame and has a receiving cavity, a feed inlet and a discharge outlet. The feed inlet is connected to the discharge outlet through the receiving cavity, and the discharge outlet is located below the loading and unloading assembly.

[0010] A switch assembly is installed on the loading and unloading assembly. The switch assembly includes a flexible blocking component and a switch driving component. The switch driving component is used to drive the flexible blocking component to open or close the discharge port.

[0011] With the above structure, the switch drive component drives the flexible blocking component to close the discharge port. The user can use the conveying mechanism to feed the fruits and vegetables to be boxed into the receiving cavity through the inlet. When the fruits and vegetables fall to the bottom of the receiving cavity, they can contact the flexible blocking component to prevent them from being damaged. At the same time, the user can place the empty fruit box used to hold the fruits and vegetables below the discharge port.

[0012] Once the receiving cavity is filled with a preset weight of fruits and vegetables, the user can stop feeding the fruits and vegetables into the receiving cavity through the inlet. Simultaneously, the switch drive component drives the flexible blocking component to open the outlet, allowing the fruits and vegetables in the outlet to fall into the fruit box under gravity, thus completing the fruit and vegetable packing. In this embodiment, the fruit and vegetable packing mechanism can pack a preset weight of fruits and vegetables into a corresponding empty fruit box at once, thereby improving the packing efficiency.

[0013] In some embodiments, the fruit and vegetable packing mechanism further includes a vertical drive assembly mounted on the frame, and the loading and unloading assembly is vertically movably mounted on the frame. The vertical drive assembly is used to drive the loading and unloading assembly to move vertically relative to the frame.

[0014] With the above structure, the vertical drive assembly is used to drive the loading and unloading assembly to move vertically relative to the frame, so that when the user inputs fruits and vegetables into the receiving cavity through the inlet, the vertical drive assembly can adjust the height of the loading and unloading assembly relative to the frame, thereby adjusting the height of the inlet relative to the frame.

[0015] When there are few fruits and vegetables in the receiving cavity, the vertical drive assembly can drive the loading and unloading assembly to move upward relative to the frame, so that the distance between the fruits and vegetables entering the inlet and the flexible blocking component is closer, thus preventing the fruits and vegetables from falling and getting injured; when there are many fruits and vegetables in the receiving cavity, the vertical drive assembly can drive the loading and unloading assembly to move downward relative to the frame, so that the distance between the discharge port and the fruit box is closer, thus preventing the fruits and vegetables from falling and getting injured during the process of falling into the fruit box.

[0016] In some embodiments, the vertical drive assembly includes a vertical drive component and a telescopic component. The vertical drive component is mounted on the top of the frame, and the telescopic component is mounted on the vertical drive component. The vertical drive component is used to drive the telescopic component to retract upward or extend downward. The loading and unloading assembly is fixed to the end of the telescopic component facing away from the vertical drive component.

[0017] With the above structure, when the vertical drive component drives the telescopic component to retract upwards, the telescopic component moves the loading / unloading assembly vertically upwards relative to the frame; when the vertical drive component drives the telescopic component to extend downwards, the telescopic component moves the loading / unloading assembly vertically downwards relative to the frame. The cooperation between the vertical drive component and the telescopic component simplifies the structure of the vertical drive assembly; and the telescopic component can continuously apply a vertically upward pulling force to the loading / unloading assembly, making the loading / unloading assembly more stable during vertical movement.

[0018] In some embodiments, the frame includes two guide rails perpendicular to the horizontal plane, and the two guide rails are located on opposite sides of the loading and unloading assembly; the loading and unloading assembly includes two guide blocks, each guide block being connected to a corresponding guide rail.

[0019] Through the above structure, the guide rail can guide the loading and unloading components via a corresponding guide block, so that the loading and unloading components can move stably vertically relative to the frame, thereby improving the overall stability of the fruit and vegetable packing mechanism.

[0020] In some embodiments, the switch driving component includes a first mounting rod and two switch driving structures, the two switch driving structures being respectively mounted on opposite sides of the loading and unloading assembly, and the opposite ends of the first mounting rod being respectively connected to the two switch driving structures; one side of the flexible blocking component is connected to the first mounting rod, and the other opposite side of the flexible blocking component is connected to one side of the loading and unloading assembly;

[0021] The switch drive structure is used to drive the first mounting rod to move between the opposite sides of the discharge port. The movement direction of the first mounting rod is perpendicular to the arrangement direction of the two switch drive structures, so that the flexible blocking component opens or closes the discharge port.

[0022] With the above structure, two switch drive structures are respectively installed on opposite sides of the loading and unloading assembly, so that the switch drive structures can drive the flexible blocking component to move more stably; the switch drive structure is used to drive the first mounting rod to move between opposite sides of the discharge port, and the end of the flexible blocking component is connected to the first mounting rod; when the first mounting rod is located on one side of the discharge port, the upper surface of the flexible blocking component can cover the discharge port to close the discharge port; when the first mounting rod is located on the other opposite side of the discharge port, the flexible blocking component can be offset from the discharge port to open the discharge port.

[0023] In some embodiments, the switch drive structure includes a rotating pusher and a rotating rod. The upper end of the rotating rod is rotatably connected to the upper end of the loading / unloading assembly, and the lower end of the rotating rod is connected to the first mounting rod. One end of the rotating pusher is rotatably connected to the loading / unloading assembly, and the other opposite end of the rotating pusher is rotatably connected to the rotating rod. The rotating pusher is used to push the rotating rod to rotate relative to the loading / unloading assembly, thereby driving the first mounting rod to move between the opposite sides of the feed inlet.

[0024] With the above structure, the upper end of the rotating rod is rotatably connected to the upper end of the loading and unloading assembly, the lower end of the rotating rod is connected to the first mounting rod, and the end of the rotating pusher is connected between the two ends of the rotating rod. This makes the distance from the connection point of the rotating pusher and the rotating rod to the rotation axis of the rotating rod less than the distance from the first mounting rod to the central axis of the rotating rod. The stroke of the rotating pusher when it pushes is less than the stroke of the first mounting rod. As a result, the size of the rotating pusher can be smaller, and the switch drive structure is easier to assemble.

[0025] In some embodiments, the loading and unloading assembly includes a main body, a vertical pulling component, and a second mounting rod. The receiving cavity, the inlet, and the outlet are all opened in the main body. The two switch driving structures are respectively installed on opposite sides of the main body. The vertical pulling component and the second mounting rod are both installed in the main body, and the vertical pulling component is located above the second mounting rod.

[0026] The flexible blocking component is connected to the vertical pulling component at one end facing away from the first mounting rod. The vertical pulling component is used to drive the flexible blocking component at one end facing away from the first mounting rod to move in the vertical direction. The second mounting rod is located on the side of the discharge port facing the vertical pulling component. The second mounting rod contacts the middle of the flexible blocking component and supports the flexible blocking component.

[0027] With the above structure, the vertical pulling component provides tension to the end of the flexible blocking component facing away from the first mounting rod, so that the flexible blocking component can be straightened when the outlet is closed, preventing fruits and vegetables from falling out through the gap between the flexible blocking component and the main body. In addition, the second mounting rod contacts the middle of the flexible blocking component and supports the flexible blocking component; so that the part of the flexible blocking component covering the outlet can be parallel to the horizontal plane and fit against the lower surface of the main body, further improving the airtightness when the outlet is closed.

[0028] In some embodiments, the vertical pulling component includes an elastic pulling member, a connecting member, and a third mounting rod. The upper end of the elastic pulling member is connected to the upper end of the main body, the lower end of the elastic pulling member is connected to the connecting member, and the third mounting rod is mounted on the connecting member.

[0029] The flexible blocking component is a belt structure. One end of the flexible blocking component is sleeved on the first mounting rod, the other opposite end of the flexible blocking component is sleeved on the third mounting rod, and the middle part of the flexible blocking component is sleeved on the second mounting rod.

[0030] With the above structure, the upper end of the elastic pull member is connected to the upper end of the main body, the lower end of the elastic pull member is connected to the connector, and the third mounting rod is installed on the connector. When the flexible blocking member closes the discharge port, the elastic pull member provides a pulling force to the third mounting rod and can also extend, so that the height of the third mounting rod is reduced. The extension of the flexible blocking member is less than the length of the discharge port, which plays a buffering role for the flexible blocking member, so as to avoid the flexible blocking member from over-extending and becoming loose.

[0031] In some embodiments, the switch assembly includes a vertical pusher, a mounting bracket, and a fourth mounting rod; the loading / unloading assembly includes a main body, an elastic reset member, a rotating bracket, a fifth mounting rod, and a sixth mounting rod.

[0032] The vertical pusher is mounted on the main body, the mounting bracket is vertically movably connected to the main body, the vertical pusher is used to drive the mounting bracket to move vertically relative to the main body, and the fourth mounting rod is mounted on the mounting bracket;

[0033] One end of the rotating frame is rotatably connected to the main body, the elastic reset member is located between the rotating frame and the main body, the fifth mounting rod is connected to the other opposite end of the rotating frame, and when the rotating frame rotates, it can drive the fifth mounting rod to move between the opposite ends of the discharge port; the sixth mounting rod is mounted on the main body.

[0034] The flexible blocking component is a belt structure. One end of the flexible blocking component is sleeved on the fourth mounting rod, the other opposite end of the flexible blocking component is sleeved on the fifth mounting rod, and the middle part of the flexible blocking component is sleeved on the sixth mounting rod.

[0035] With the above structure, the vertical pusher is used to push the mounting frame to move in the vertical direction, thereby driving the fourth mounting rod to move in the vertical direction, thus changing the height of the upper end of the flexible blocking component. When the height of the upper end of the flexible blocking component is low, the elastic reset component drives the rotating frame to rotate to a position perpendicular to the horizontal plane, and the flexible blocking component can cover the entire discharge port.

[0036] When the upper end of the flexible blocking component is high, it can pull the fifth mounting rod to move, causing the rotating frame to rotate and the discharge port to open. The elastic reset component provides elastic force to the rotating frame. When the upper end of the flexible blocking component is lowered again, the elastic reset component can drive the rotating frame to reset and close the discharge port again.

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

[0038] Compared to existing technologies, the switch-driven component activates the flexible blocking component to close the discharge port. Users can then feed the fruits and vegetables to be boxed into the receiving cavity via the inlet using a conveying mechanism. When the fruits and vegetables fall to the bottom of the receiving cavity, they come into contact with the flexible blocking component, preventing injury. Simultaneously, users can place empty fruit boxes below the discharge port.

[0039] Once the receiving cavity is filled with a preset weight of fruits and vegetables, the user can stop feeding the fruits and vegetables into the receiving cavity through the inlet. Simultaneously, the switch drive component drives the flexible blocking component to open the outlet, allowing the fruits and vegetables in the outlet to fall into the fruit box under gravity, thus completing the fruit and vegetable packing. In this embodiment, the fruit and vegetable packing mechanism can pack a preset weight of fruits and vegetables into a corresponding empty fruit box at once, thereby improving the packing efficiency.

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.

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

[0051] Please refer to Figure 1 and Figure 2One embodiment of this utility model discloses a fruit and vegetable packing mechanism 100, including a frame 10, a loading and unloading assembly 20, and a switch assembly 30. The loading and unloading assembly 20 is installed on the frame 10 and has a receiving cavity 2202, a feeding port 2204, and a discharging port 2206. The feeding port 2204 is connected to the discharging port 2206 through the receiving cavity 2202, and the discharging port 2206 is located below the loading and unloading assembly 20. The switch assembly 30 is installed on the loading and unloading assembly 20 and includes a flexible blocking component 32 and a switch driving component 34. The switch driving component 34 is used to drive the flexible blocking component 32 to open or close the discharging port 2206.

[0052] With the above structure, the switch drive component 34 drives the flexible blocking component 32 to close the discharge port 2206. The user can use the conveying mechanism to feed the fruits and vegetables to be boxed into the receiving cavity 2202 through the inlet 2204. When the fruits and vegetables fall into the bottom of the receiving cavity 2202, they can contact the flexible blocking component 32 to avoid injury. At the same time, the user can place the empty fruit box for holding fruits and vegetables below the discharge port 2206.

[0053] Once the receiving cavity 2202 is filled with a preset weight of fruits and vegetables, the user can stop feeding the fruits and vegetables into the receiving cavity 2202 through the inlet 2204. Simultaneously, the switch drive component 34 drives the flexible blocking component 32 to open the outlet 2206. The fruits and vegetables in the outlet 2206 fall into the fruit box under gravity, thus completing the fruit and vegetable packing. In this embodiment, the fruit and vegetable packing mechanism 100 can pack a preset weight of fruits and vegetables into a corresponding empty fruit box at once, thereby improving the packing efficiency.

[0054] Specifically, in this embodiment, the frame 10 may include steel plates and steel bars spliced ​​together, and the frame 10 as a whole may be a hollow frame structure; the loading and unloading assembly 20 may move vertically relative to the fruit and vegetable packing mechanism 100, and the loading and unloading assembly 20 as a whole may be a cuboid-like structure, the inlet 2204 may be located on one side of the loading and unloading assembly 20, and both the inlet 2204 and the outlet 2206 may be rectangular openings.

[0055] The flexible blocking component 32 may include an elastic annular belt, and the width of the flexible blocking component 32 may be equal to or greater than the width of the discharge port 2206. The switch driving component 34 may include a cylinder-driven rotating structure. One end of the flexible blocking component 32 may be sleeved on the rotating structure, and the other opposite end of the flexible blocking component 32 may be sleeved on the loading and unloading assembly 20. The rotating structure can drive the end of the flexible blocking component 32 to move between the opposite sides of the discharge port 2206, so that the flexible blocking component 32 covers the discharge port 2206 or is offset from the discharge port 2206, so as to realize the opening or closing of the discharge port 2206 by the flexible blocking component 32.

[0056] In other embodiments, the frame 10 may also include other structures, such as a hollow box structure; the loading and unloading assembly 20 may also be in other shapes, such as a cylinder or a column with a polygonal cross-section; the switching assembly 30 may also include other structures, such as a flexible stop driven by a motor, which can cover the discharge port 2206 or be offset from the discharge port 2206.

[0057] In some embodiments, the fruit and vegetable packing mechanism 100 further includes a vertical drive assembly 40, which is mounted on the frame 10. The loading and unloading assembly 20 is vertically movably mounted on the frame 10. The vertical drive assembly 40 is used to drive the loading and unloading assembly 20 to move vertically relative to the frame 10.

[0058] With the above structure, the vertical drive assembly 40 is used to drive the loading and unloading assembly 20 to move vertically relative to the frame 10, so that when the user inputs fruits and vegetables into the receiving cavity 2202 through the inlet 2204, the vertical drive assembly 40 can adjust the height of the loading and unloading assembly 20 relative to the frame 10, thereby adjusting the height of the inlet 2204 relative to the frame 10.

[0059] When there are few fruits and vegetables in the receiving cavity 2202, the vertical drive assembly 40 can drive the loading and unloading assembly 20 to move upward relative to the frame 10, so that the distance between the fruits and vegetables entering the feed inlet 2204 and the flexible blocking component 32 is closer, so as to avoid the fruits and vegetables from falling and getting injured; when there are many fruits and vegetables in the receiving cavity 2202, the vertical drive assembly 40 can drive the loading and unloading assembly 20 to move downward relative to the frame 10, so that the distance between the discharge outlet 2206 and the fruit box is closer, so as to avoid the fruits and vegetables from falling and getting injured during the process of falling into the fruit box.

[0060] Specifically, in this embodiment, the vertical drive component 40 may include a belt roll driven by a motor, and one end of the belt roll that extends out may be fixed to the loading and unloading component 20; the vertical drive component 40 drives the belt roll to rotate in a preset direction, the extended part of the belt roll grows longer, and the loading and unloading component 20 moves downward; the vertical drive component 40 drives the belt roll to rotate away from the preset direction, the extended part of the belt roll shortens, and the loading and unloading component 20 moves upward.

[0061] In other embodiments, the vertical drive assembly 40 may also include other structures, such as a cylinder with the piston rod positioned perpendicular to the horizontal plane.

[0062] In some embodiments, the vertical drive assembly 40 includes a vertical drive component 42 and a telescopic component 44. The vertical drive component 42 is mounted on the top of the frame 10, and the telescopic component 44 is mounted on the vertical drive component 42. The vertical drive component 42 is used to drive the telescopic component 44 to retract upward or extend downward. The loading and unloading assembly 20 is fixed to one end of the telescopic component 44 facing away from the vertical drive component 42.

[0063] With the above structure, when the vertical drive component 42 drives the telescopic component 44 to retract upwards, the telescopic component 44 causes the loading / unloading assembly 20 to move vertically upwards relative to the frame 10; when the vertical drive component 42 drives the telescopic component 44 to extend downwards, the telescopic component 44 causes the loading / unloading assembly 20 to move vertically downwards relative to the frame 10. The vertical drive component 42 and the telescopic component 44 cooperate with each other, which simplifies the structure of the vertical drive assembly 40; and the telescopic component 44 can continuously apply a vertically upward pulling force to the loading / unloading assembly 20, making the loading / unloading assembly 20 more stable during vertical movement.

[0064] Specifically, the vertical drive component 42 may include an electric motor, and the telescopic component 44 may include a belt reel, which may be mounted on the drive shaft of the electric motor.

[0065] In some embodiments, the frame 10 includes two guide rails 12, which are perpendicular to the horizontal plane and are located on opposite sides of the loading and unloading assembly 20. The loading and unloading assembly 20 includes two guide blocks 21, each of which is connected to a corresponding guide rail 12.

[0066] Through the above structure, the guide rail 12 can guide the loading and unloading assembly 20 through a corresponding guide block 21, so that the loading and unloading assembly 20 can move vertically relative to the frame 10 stably, thereby improving the overall stability of the fruit and vegetable packing mechanism 100.

[0067] Specifically, the guide rail 12 may include a strip-shaped protrusion, which may be embedded in the guide block 21 so that the guide block 21 can move vertically relative to the guide rail 12; the two guide rails 12 may be located at the two corners on the same side of the loading and unloading assembly 20, so that the two guide rails 12 are located on opposite sides of the loading and unloading assembly 20.

[0068] Please refer to Figure 3 and Figure 4 In some embodiments, the switch driving component 34 includes a first mounting rod 342 and two switch driving structures 344, which are respectively mounted on opposite sides of the loading and unloading assembly 20. The opposite ends of the first mounting rod 342 are respectively connected to the two switch driving structures 344. One side of the flexible blocking component 32 is connected to the first mounting rod 342, and the other opposite side of the flexible blocking component 32 is connected to one side of the loading and unloading assembly 20.

[0069] The switch drive structure 344 is used to drive the first mounting rod 342 to move between the opposite sides of the discharge port 2206. The movement direction of the first mounting rod 342 is perpendicular to the arrangement direction of the two switch drive structures 344, so that the flexible blocking component 32 opens or closes the discharge port 2206.

[0070] With the above structure, two switch drive structures 344 are respectively installed on opposite sides of the loading and unloading assembly 20, so that the switch drive structure 344 can drive the flexible blocking component 32 to move more stably; the switch drive structure 344 is used to drive the first mounting rod 342 to move between opposite sides of the discharge port 2206, and the end of the flexible blocking component 32 is connected to the first mounting rod 342; when the first mounting rod 342 is located on one side of the discharge port 2206, the upper surface of the flexible blocking component 32 can cover the discharge port 2206 to close the discharge port 2206; when the first mounting rod 342 is located on the other opposite side of the discharge port 2206, the flexible blocking component 32 can be offset from the discharge port 2206 to open the discharge port 2206.

[0071] Specifically, in this embodiment, the switch drive structure 344 may include a cylinder and a rotating rod structure, which drives the rotating rod structure to rotate so as to move the first mounting rod 342 relative to the discharge port 2206 of the loading and unloading assembly 20.

[0072] In other embodiments, the switch drive structure 344 may also include other structures, such as a motor-driven slider structure, wherein the first mounting rod 342 may be fixed to the slider.

[0073] In some embodiments, the switch drive structure 344 includes a rotating pusher 3442 and a rotating rod 3444. The upper end of the rotating rod 3444 is rotatably connected to the upper end of the loading / unloading assembly 20, and the lower end of the rotating rod 3444 assembly is connected to the first mounting rod 342. One end of the rotating pusher 3442 is rotatably connected to the loading / unloading assembly 20, and the other opposite end of the rotating pusher 3442 is rotatably connected to the rotating rod 3444. The rotating pusher 3442 is used to push the rotating rod 3444 to rotate relative to the loading / unloading assembly 20, so as to drive the first mounting rod 342 to move between the opposite sides of the discharge port 2206.

[0074] With the above structure, the upper end of the rotating rod 3444 is rotatably connected to the upper end of the loading / unloading assembly 20, the lower end of the rotating rod 3444 is connected to the first mounting rod 342, and the end of the rotating pusher 3442 is connected between the two ends of the rotating rod 3444. This makes the distance from the connection point of the rotating pusher 3442 and the rotating rod 3444 to the rotation axis of the rotating rod 3444 less than the distance from the first mounting rod 342 to the central axis of the rotating rod 3444. The stroke of the rotating pusher 3442 when it pushes is less than the stroke of the first mounting rod 342. As a result, the size of the rotating pusher 3442 can be smaller, and the switch drive structure 344 is easier to assemble.

[0075] Specifically, in this embodiment, the rotating pusher 3442 may include a cylinder. The cylinder body of the rotating pusher 3442 can be rotatably connected to the loading and unloading assembly 20 via a rotating shaft. The piston rod of the rotating pusher 3442 cylinder can be rotatably connected to the middle of the rotating rod 3444 via a bearing. The connection between the pusher and the rotating rod 3444 can be closer to the end of the rotating axis of the rotating rod 3444.

[0076] In other embodiments, the rotating pusher 3442 may also include other structures, such as a slider driven by an electric motor; the connection between the rotating pusher 3442 and the rotating rod 3444 may be closer to the end where the first mounting rod 342 is located.

[0077] In some embodiments, the loading and unloading assembly 20 includes a main body 22, a vertical pulling component 23, and a second mounting rod 24. The receiving cavity 2202, the feed port 2204, and the discharge port 2206 are all opened on the main body 22. Two switch drive structures 344 are respectively installed on opposite sides of the main body 22. The vertical pulling component 23 and the second mounting rod 24 are both installed on the main body 22, with the vertical pulling component 23 located above the second mounting rod 24.

[0078] The end of the flexible blocking component 32 facing away from the first mounting rod 342 is connected to the vertical pulling component 23. The vertical pulling component 23 is used to drive the end of the flexible blocking component 32 facing away from the first mounting rod 342 to move in the vertical direction. The second mounting rod 24 is located on the side of the discharge port 2206 facing the vertical pulling component 23. The second mounting rod 24 contacts the middle of the flexible blocking component 32 and supports the flexible blocking component 32.

[0079] With the above structure, the vertical pulling component 23 provides a pulling force to the end of the flexible blocking component 32 facing away from the first mounting rod 342, so that the flexible blocking component 32 can be straightened when the discharge port 2206 is closed, preventing fruits and vegetables from falling out through the gap between the flexible blocking component 32 and the main body 22. In addition, the second mounting rod 24 contacts the middle of the flexible blocking component 32 and supports the flexible blocking component 32; so that the part of the flexible blocking component 32 covering the discharge port 2206 can be parallel to the horizontal plane and fit against the lower surface of the main body 22, further improving the airtightness of the discharge port 2206 when closed.

[0080] Specifically, the flexible blocking component 32 can be made of elastic materials such as rubber or soft leather; the flexible blocking component 32 can be a ring structure with its ends connected, one end of the flexible blocking component 32 being sleeved on the first mounting rod 342, and the middle part of the flexible blocking component 32 being sleeved on the second mounting rod 24. The vertical pulling component 23 can include an elastic material so that the vertical pulling component 23 can buffer the flexible blocking component 32. The vertical pulling component 23 and the second mounting rod 24 are both located between the two switch drive structures 344.

[0081] In some embodiments, the vertical pulling component 23 includes an elastic pulling member 232, a connecting member 234, and a third mounting rod 236. The upper end of the elastic pulling member 232 is connected to the upper end of the main body 22, the lower end of the elastic pulling member 232 is connected to the connecting member 234, and the third mounting rod 236 is mounted on the connecting member 234.

[0082] The flexible blocking component 32 is a belt structure. One end of the flexible blocking component 32 is sleeved on the first mounting rod 342, the other opposite end of the flexible blocking component 32 is sleeved on the third mounting rod 236, and the middle part of the flexible blocking component 32 is sleeved on the second mounting rod 24.

[0083] With the above structure, the upper end of the elastic pull member 232 is connected to the upper end of the main body 22, the lower end of the elastic pull member 232 is connected to the connector 234, and the third mounting rod 236 is mounted on the connector 234. When the flexible blocking member 32 closes the discharge port 2206, the elastic pull member 232 can extend while providing a pulling force to the third mounting rod 236, so that the height of the third mounting rod 236 is reduced. The extension of the flexible blocking member 32 is less than the length of the discharge port 2206, which plays a buffering role for the flexible blocking member 32 to avoid the flexible blocking member 32 from over-extension and loosening.

[0084] Specifically, in this embodiment, the elastic pull member 232 can have the same structure as the flexible blocking member 32. The upper end of the elastic pull member 232 is sleeved on the upper end of the main body 22, and the lower end of the elastic pull member 232 can be sleeved on the connector 234. The connector 234 can be a hollow block structure, and the third mounting rod 236 can be installed on the lower end of the connector 234.

[0085] In other embodiments, the elastic pull member 232 may also be other structures, such as a tension spring.

[0086] Please refer to Figure 5 In some other embodiments, the switch assembly 30 includes a vertical pusher 36, a mounting bracket 38, and a fourth mounting rod 39; the loading / unloading assembly 20 includes a main body 22, an elastic reset member, a rotating bracket 25, a fifth mounting rod 26, and a sixth mounting rod 27.

[0087] A vertical pusher 36 is mounted on the main body 22, and a mounting bracket 38 is vertically movably connected to the main body 22. The vertical pusher 36 is used to drive the mounting bracket 38 to move vertically relative to the main body 22, and a fourth mounting rod 39 is mounted on the mounting bracket 38.

[0088] One end of the rotating frame 25 is rotatably connected to the main body 22. The elastic reset member is located between the rotating frame 25 and the main body 22. The fifth mounting rod 26 is connected to the other opposite end of the rotating frame 25. When the rotating frame 25 rotates, it can drive the fifth mounting rod 26 to move between the opposite ends of the discharge port 2206. The sixth mounting rod 27 is installed on the main body 22.

[0089] The flexible blocking component 32 is a belt structure. One end of the flexible blocking component 32 is sleeved on the fourth mounting rod 39, the other opposite end of the flexible blocking component 32 is sleeved on the fifth mounting rod 26, and the middle part of the flexible blocking component 32 is sleeved on the sixth mounting rod 27.

[0090] With the above structure, the vertical pusher 36 is used to push the mounting bracket 38 to move in the vertical direction, thereby driving the fourth mounting rod 39 to move in the vertical direction, thereby changing the height of the upper end of the flexible blocking member 32. When the height of the upper end of the flexible blocking member 32 is low, the elastic reset member drives the rotating bracket 25 to rotate to a position perpendicular to the horizontal plane, and the flexible blocking member 32 can cover the entire discharge port 2206.

[0091] When the upper end of the flexible blocking component 32 is at a high height, the flexible blocking component 32 can pull the fifth mounting rod 26 to move, drive the rotating frame 25 to rotate, open the discharge port 2206, and the elastic reset component provides elastic force to the rotating frame 25. When the position of the upper end of the flexible blocking component 32 is lowered again, the elastic reset component can drive the rotating frame 25 to reset and close the discharge port 2206 again.

[0092] Specifically, the vertical pushing member 36 may include a cylinder, and the cylinder body of the vertical pushing member 36 may be fixed to the main body 22; the mounting frame 38 may be a steel frame structure, and the mounting frame 38 may move vertically relative to the main body 22; the rotating frame 25 may include two rod-shaped rotating structures, which are located on opposite sides of the main body 22; the elastic reset member may be a torsion spring, and the two ends of the elastic reset member are respectively connected to the rotating frame 25 and the main body 22; the fifth mounting rod 26 is installed between the two rod-shaped rotating structures; the portion of the flexible blocking member 32 between the fourth mounting rod 39 and the sixth mounting rod 27 may be perpendicular to the horizontal plane, and the portion of the flexible blocking member 32 between the fifth mounting rod 26 and the sixth mounting rod 27 may be parallel to the horizontal plane.
