Description

Technical Field

[0001] This application relates to the field of fruit and vegetable sorting technology, and in particular to a liquid flow control module, a fruit and vegetable transport device, and a fruit and vegetable sorting equipment. Background Technology

[0002] In the process of fruit and vegetable processing and distribution, fruit and vegetable transport devices with water tanks are often used to clean, buffer, or transport fruits and vegetables using water flow. The water tank is designed to allow fruits and vegetables (such as apples, navel oranges, etc.) to float and move forward in the water tank, reducing collision damage during transportation.

[0003] However, in existing fruit and vegetable transport devices, the size of the water inlet is not adjustable, resulting in a constant or difficult-to-adjust liquid flow rate into the water tank. Different types, sizes, or conditions of fruits and vegetables require different water flow intensities. Excessive water flow may damage fragile fruits and vegetables or cause unnecessary water waste and energy consumption; while insufficient water flow may fail to effectively support or move the fruits and vegetables, affecting transport efficiency and cleaning effectiveness. Therefore, existing technologies generally suffer from the technical problem of fixed liquid flow rates at the water inlet, making it difficult to flexibly adjust according to actual needs and adapt to diverse fruit and vegetable processing requirements. Utility Model Content

[0004] One objective of this application is to provide a liquid flow control module, a fruit and vegetable transport device, and a fruit and vegetable sorting device to solve the technical problem in related technologies where the liquid flow rate at the water supply in the fruit and vegetable transport device is fixed and difficult to adjust flexibly according to actual needs.

[0005] In a first aspect, embodiments of this application provide a liquid flow control module applied to a fruit and vegetable transport device. The fruit and vegetable transport device is equipped with a water tank, and the bottom surface of the water tank is provided with a water inlet located at the front end of the water tank. The liquid flow control module includes:

[0006] A pressure plate extends in the width direction of the water tank and is located above the water inlet;

[0007] A lifting mechanism is located above and connected to the pressure plate, and is used to control the lifting of the pressure plate to adjust the distance between the pressure plate and the water supply port.

[0008] The above structure enables convenient and controllable adjustment of the liquid flow rate at the water inlet of the fruit and vegetable transport device's water tank. Furthermore, by adjusting the distance between the pressure plate and the water inlet, users can flexibly set and change the water flow intensity and flow rate entering the water tank according to the type of fruit and vegetable being processed (such as fragile cherries or harder apples), their size, and specific fruit and vegetable processing needs. This helps protect the fruit and vegetables from impact damage during transportation and improves their quality.

[0009] Optionally, the lifting mechanism includes:

[0010] An upper fixing plate is located above the pressure plate;

[0011] A movable plate is disposed between the upper fixed plate and the pressure plate;

[0012] A driving element is mounted on the upper fixed plate and drives the movable plate to move the movable plate up and down.

[0013] A fixed column, one end of which is fixedly connected to the fixed plate, and the other end of which is fixedly connected to the pressure plate.

[0014] Through the above structure, the lifting mechanism forms a clear power transmission path: the drive element drives the movable plate, and the movable plate drives the pressure plate through the fixed column. This structure has better rigidity and stability, ensuring that the pressure plate rises and falls smoothly and reliably, thereby achieving more stable regulation of liquid flow.

[0015] Optionally, the liquid flow control module also includes:

[0016] A lower fixed plate is disposed between the movable plate and the pressure plate;

[0017] A guide shaft, one end of which is fixedly connected to the pressure plate, and the other end of which passes through the lower fixed plate, the movable plate and the upper fixed plate in sequence. The guide shaft is slidably engaged with the upper fixed plate and the lower fixed plate respectively.

[0018] The above structure significantly enhances the guiding performance and operational stability of the lifting mechanism, ensuring that the pressure plate moves strictly along the predetermined vertical trajectory during the lifting process, and effectively preventing tilting, swaying or jamming caused by uneven driving force, lateral force interference or structural gaps.

[0019] Optionally, the liquid flow control module further includes an upper limit stop, which is installed on the movable plate and is used to abut against the upper fixed plate when the movable plate rises to a preset upper limit height, so as to limit the movable plate from rising further.

[0020] The aforementioned structure provides a reliable travel limit for the upward movement of the lifting mechanism. This improves the safety and reliability of equipment operation and defines the maximum opening position of the pressure plate. It effectively prevents the movable plate from rising excessively due to control errors or excessive driving force, avoiding potential impacts, stress overloads, or damage to drive components, connectors, or other structural parts.

[0021] Optionally, the upper limit positioner is threadedly connected to the movable plate, and the upper limit positioner can adjust its height relative to the movable plate by threading with the movable plate, thereby adjusting the preset upper limit height of the movable plate.

[0022] The above structure enables flexible adjustment of the upper limit of the movable plate's travel distance.

[0023] Optionally, the liquid flow control module further includes a lower limit member, which is installed on the lower fixed plate and is used to abut against the movable plate when the movable plate descends to a preset lower height limit, so as to limit the movable plate from continuing to descend.

[0024] The aforementioned structure provides reliable travel limits for the downward movement of the lifting mechanism, improving the safety and reliability of equipment operation and defining the minimum clearance position or closed state of the pressure plate. It effectively prevents the movable plate from descending excessively due to control errors or external forces, avoiding direct impact of the pressure plate on the water supply structure or the bottom of the water tank, thus protecting the pressure plate, water supply, and related components from damage. Simultaneously, it ensures that the minimum distance between the pressure plate and the water supply reaches and remains at the preset value.

[0025] Optionally, the lower limit member is threadedly connected to the lower fixed plate, and the lower fixed plate can adjust its height relative to the lower fixed plate by thread engagement with the lower fixed plate, so as to adjust the preset lower limit of the movable plate.

[0026] Through the above structure and the above settings, this application embodiment achieves flexible adjustment of the lower limit of the movable plate's travel distance.

[0027] Optionally, the center planes of the upper fixed plate, the lower fixed plate, the movable plate, and the pressure plate are aligned with each other in the length direction, and the driving element is located on the center plane of the upper fixed plate in the length direction.

[0028] With the above structure, the entire lifting mechanism is roughly symmetrically arranged, ensuring the balanced application and transmission of driving force and minimizing adverse effects such as eccentric loads.

[0029] In a second aspect, embodiments of this application also provide a fruit and vegetable transport device, comprising:

[0030] The conveyor platform is equipped with a water tank, and the bottom surface of the water tank is provided with a water inlet, which is located at the front end of the water tank.

[0031] The liquid flow control module as described in any of the above is installed on the conveying platform. The pressure plate of the liquid flow control module is located above the water supply port. The liquid flow control module is used to adjust the distance between the pressure plate and the water supply port by controlling the lifting and lowering of the pressure plate.

[0032] In a third aspect, embodiments of this application also provide a fruit and vegetable sorting device, including the fruit and vegetable transport device as described above.

[0033] The embodiments of this application achieve the following technical effects: By setting a liftable pressure plate that acts directly above the water inlet, the embodiments of this application realize convenient and controllable adjustment of the liquid flow rate at the water inlet of the fruit and vegetable transport device's water tank. Furthermore, by adjusting the distance between the pressure plate and the water inlet, users can flexibly set and change the water flow intensity and flow rate entering the water tank according to the type and size of the fruits and vegetables being processed, as well as specific fruit and vegetable processing needs. This helps protect the fruits and vegetables from impact damage during transportation and improves their quality. Attached Figure Description

[0040] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or one or more intermediate elements can exist between them. The terms "upper," "lower," "left," "right," "upper end," "lower end," "top," and "bottom," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore should not be construed as a limitation of 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.

[0041] 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.

[0042] In the fruit and vegetable sorting industry, some fruits and vegetables, such as apples, cherries, and winter melons, are transported using water power to improve transportation efficiency.

[0043] However, while the hydraulic water delivery methods used in related technologies can effectively buffer and reduce physical collisions, the water flow at the water supply is usually constant or difficult to control. Different types, sizes, and even ripeness of fruits and vegetables have different requirements for the supporting and propelling force of the water flow. For example, when handling fragile cherries or strawberries, an excessively strong water flow can easily cause impact damage.

[0044] To resolve the aforementioned technical issues, please refer to the following: Figure 1 and Figure 2 In a first aspect, embodiments of this application provide a liquid flow control module 100, applied to a fruit and vegetable transport device 1000. The fruit and vegetable transport device 1000 is provided with a water tank 201, and a water inlet 202 is provided on the bottom surface of the water tank 201. The water inlet 202 is located at the front end of the water tank 201. The liquid flow control module 100 includes a pressure plate 10 and a lifting mechanism 20. The pressure plate 10 extends in the width direction of the water tank 201 and is located above the water inlet 202. The lifting mechanism 20 is disposed above the pressure plate 10 and connected to the pressure plate 10, and is used to control the lifting and lowering of the pressure plate 10 to adjust the distance D between the pressure plate 10 and the water inlet 202.

[0045] The liquid flow control module 100 of this application embodiment has the following structural principle: The fruit and vegetable transport device 1000 is provided with a water tank 201 and a water inlet 202 disposed on the bottom surface of the water tank 201. The water inlet 202 is located at the bottom front end of the water tank 201, and can supply clean water or preservative liquid into the water tank 201. The liquid flow control module 100 includes a pressure plate 10 and a lifting mechanism 20. The pressure plate 10 is configured to extend in the width direction of the water tank 201, and its installation position is located directly above the water inlet 202 at the bottom front end of the water tank 201. The lifting mechanism 20 is installed above the pressure plate 10 and connected to the pressure plate 10.

[0046] The lifting mechanism 20 provides power and transmission to control the vertical movement of the pressure plate 10. By driving the pressure plate 10 to rise or fall, the lifting mechanism 20 changes the vertical distance between the bottom of the pressure plate 10 and the water supply port 202. This distance directly determines the cross-sectional area of ​​the water flow channel from the water supply port 202. When the pressure plate 10 descends closer to the water supply port 202, the gap decreases, the water flow resistance increases, and the flow rate decreases; conversely, when the pressure plate 10 rises away from the water supply port 202, the gap increases, the water flow resistance decreases, and the flow rate increases.

[0047] Understandably, this embodiment of the application achieves convenient and controllable adjustment of the liquid flow rate at the water supply inlet 202 within the water tank 201 of the fruit and vegetable transport device 1000 by setting a liftable pressure plate 10 that acts directly above the water supply inlet 202. Furthermore, by adjusting the distance between the pressure plate 10 and the water supply inlet 202, users can flexibly set and change the water flow intensity and flow rate entering the water tank 201 according to the type of fruit and vegetables being processed (e.g., fragile cherries or harder apples), their size, and specific fruit and vegetable processing needs. This helps protect the fruit and vegetables from impact damage during transportation and improves their quality.

[0048] In addition, the water inlet 202 in the relevant technical content is often set on the side wall of the water tank 201 and supplies water along the length of the water tank 201. Since the water inlet 202 is much smaller than the width of the water tank 201, part of the water flow output from the water inlet 202 is prone to form eddies in the water tank 201, which affects the forward transportation of fruits and vegetables and reduces the transportation efficiency of fruits and vegetables.

[0049] Please see Figure 3In this embodiment, the pressure plate 10 extends along the width of the water tank 201, and the water inlet 202 is located at the front end of the water tank 201. Water jets vertically upwards from the bottom water inlet 202, first encountering the pressure plate 10, which forces the water flow to change direction, transforming it from vertical to diffuse outwards, primarily towards the front and sides. The pressure plate 10 acts as a buffer and guide, ensuring that the water entering the main area of ​​the water tank 201 is not a direct, strong jet, but rather a more uniform, upward, and forward-flowing water flow. The water flow pattern formed by the water supply structure in this embodiment results in a more uniform energy distribution and reduces the likelihood of large vortices forming in the main channel. Furthermore, by adjusting the distance between the pressure plate 10 and the water inlet 202, the cross-sectional area and flow velocity of the water outlet can be controlled.

[0050] Specifically, in this embodiment, since the pressure plate 10 extends along the width of the water tank 201 and the water inlet 202 is located at the front end of the water tank 201, a portion of the water flow output from the water inlet 202 changes direction after being blocked by the pressure plate 10 and moves towards the length of the water tank 201; another portion of the water flow output from the water inlet 202 changes direction after being blocked by the pressure plate 10 and moves towards the tank wall of the water tank 201 near the water inlet 202, and then flows back after being blocked by the tank wall, continuing to move towards the length of the water tank 201. In this embodiment, because the water flow from the water inlet 202, after being blocked by the pressure plate 10 and the tank wall near the water inlet 201, converges and flows directly forward, it is less likely to form eddies within the water tank 201, thus ensuring the efficient transportation of fruits and vegetables.

[0051] In some embodiments, the lifting mechanism 20 includes an upper fixed plate 21, a movable plate 22, a driving element 23, and a fixed column 24. The upper fixed plate 21 is disposed above the pressure plate 10, and the movable plate 22 is disposed between the upper fixed plate 21 and the pressure plate 10. The driving element 23 is mounted on the upper fixed plate 21 and drives the movable plate 22 to move up and down. One end of the fixed column 24 is fixedly connected to the fixed plate, and the other end is fixedly connected to the pressure plate 10.

[0052] Understandably, the upper fixed plate 21 serves as the top support structure of the entire lifting mechanism 20, stably mounted above the pressure plate 10. The movable plate 22, located between the upper fixed plate 21 and the pressure plate 10, is the main carrier for achieving lifting motion. The drive element 23, such as a cylinder, electric push rod, or motor screw mechanism, is mounted on the upper fixed plate 21, and its output end is driven by the movable plate 22, providing the power for the movable plate 22 to move vertically relative to the upper fixed plate 21. The fixed column 24 is a rigid component connecting the movable plate 22 and the pressure plate 10, with one end fixed to the movable plate 22 and the other end fixedly connected to the pressure plate 10 below. Therefore, when the drive element 23 drives the movable plate 22 to move up and down, the movable plate 22 drives the pressure plate 10 to move vertically at the same amplitude through the fixed column 24, thereby achieving accurate control of the position of the pressure plate 10. The embodiments of this application establish a clear power transmission path through the above structure: the driving element 23 drives the movable plate 22, and the movable plate 22 drives the pressure plate 10 through the fixed column 24. This structure has better rigidity and stability, ensuring that the pressure plate 10 rises and falls smoothly and reliably, thereby achieving more stable regulation of the liquid flow rate.

[0053] For example, each end of the fixed column 24 is provided with a threaded hole in the axial direction, and the movable plate 22 and the pressure plate 10 are provided with through holes that align with the corresponding threaded holes. By passing screws through the through holes and threaded holes in sequence and engaging with the threaded holes, the fixed column 24 can be fixedly connected to the movable plate 22 or the pressure plate 10.

[0054] In some embodiments, the liquid flow control module 100 further includes a lower fixed plate 25 and a guide shaft 26. The lower fixed plate 25 is disposed between the movable plate 22 and the pressure plate 10. One end of the guide shaft 26 is fixedly connected to the pressure plate 10, and the other end passes through the lower fixed plate 25, the movable plate 22, and the upper fixed plate 21 in sequence. The guide shaft 26 is slidably engaged with the upper fixed plate 21 and the lower fixed plate 25, respectively.

[0055] Understandably, the guide shaft 26 is a guiding element, with one end fixedly connected to the pressure plate 10 and extending vertically upward. The guide shaft 26 passes sequentially through the lower fixed plate 25, the movable plate 22, and the upper fixed plate 21. The guide shaft 26 forms a sliding fit with the upper fixed plate 21 and the lower fixed plate 25, meaning that the guide shaft 26 can slide smoothly axially within the holes of these two fixed plates, but it is constrained in the lateral position. When the movable plate 22 drives the pressure plate 10 to rise and fall via the fixed column 24, the guide shaft 26 fixed to the pressure plate 10 will move vertically along with it and slide under the constraint of the upper and lower fixed plates 21 and 25.

[0056] This embodiment of the application significantly enhances the guiding performance and operational stability of the lifting mechanism 20 by setting a lower fixed plate 25 and a guide shaft 26. This ensures that the pressure plate 10 moves strictly along a predetermined vertical trajectory during lifting, effectively preventing tilting, swaying, or jamming caused by uneven driving force, lateral force interference, or structural gaps. The sliding cooperation between the guide shaft 26 and the upper and lower fixed plates 21 and 25 provides precise linear guidance for the movement of the pressure plate 10, greatly improving the smoothness of movement and positioning accuracy. The addition of the lower fixed plate 25 provides the guide shaft 26 with a larger span of support and guiding reference, further enhancing the structural rigidity and anti-eccentric load capacity of the entire moving component, specifically the structural rigidity and anti-eccentric load capacity of the moving plate 22, fixed column 24, pressure plate 10, and guide shaft 26. This allows the pressure plate 10 to adjust the distance to the water supply port 202 more stably and smoothly, ensuring the accuracy and reliability of liquid flow regulation and extending the service life of the mechanism.

[0057] Please review Figure 2 In some embodiments, the lower fixing plate 25 is provided with a clearance hole 252 for the fixing post 24. The fixing post 24 passes through the clearance hole 252 and is connected to the movable plate 22 and the pressure plate 10 respectively. The upper fixing plate 21 and the lower fixing plate 25 can be fastened to the side wall of the water tank 201 by bolts.

[0058] In some embodiments, the upper fixing plate 21 includes an upper connecting flange 211, which is fixed to the body of the upper fixing plate 21 and sleeved on the guide shaft 26, with a clearance fit. The guide shaft 26 is axially sliding relative to the upper connecting flange 211. The lower fixing plate 25 includes a lower connecting flange 251, which is fixed to the body of the lower fixing plate 25 and sleeved on the guide shaft 26, with a clearance fit. The guide shaft 26 is axially sliding relative to the lower connecting flange 251.

[0059] Please review Figure 1 and Figure 2 In some embodiments, the liquid flow control module 100 further includes an upper limit member 27, which is installed on the movable plate 22 and is used to abut against the fixed plate 21 when the movable plate 22 rises to the preset upper limit height, so as to limit the movable plate 22 from continuing to rise.

[0060] Understandably, the upper limit stop 27 is installed on the upper surface of the movable plate 22 or at another specific location. When the drive element 23 drives the movable plate 22 to move upward, the upper limit stop 27 rises along with the movable plate 22. Once the movable plate 22 reaches the preset maximum allowable rising height, i.e., the preset upper limit height, the upper limit stop 27 installed thereon will make physical contact with the fixed upper plate 21, forming a mechanical block. This limiting contact relationship prevents the movable plate 22 from continuing to move upward, even if the drive element 23 is still applying an upward driving force or the control signal has not stopped.

[0061] This embodiment of the application provides a reliable travel limit for the upward movement of the lifting mechanism 20 by setting an upper limit member 27. This improves the safety and reliability of equipment operation and defines the maximum opening position of the pressure plate 10. It effectively prevents the movable plate 22 from rising excessively due to control errors or excessive driving force, avoiding potential impacts, stress overloads, or damage to the drive element 23, connectors, or other structural components.

[0062] In some embodiments, the upper limit member 27 is threadedly connected to the movable plate 22, and the upper limit member 27 can adjust its height relative to the movable plate 22 by threading with the movable plate 22, so as to adjust the preset upper limit of the height of the movable plate 22.

[0063] Understandably, the upper limit stop 27 can be an adjusting bolt or a threaded stop, and the upper limit stop 27 is installed with the movable plate 22 via a threaded connection. This threaded connection allows the upper limit stop 27 to be adjusted in height relative to the movable plate 22. By rotating the upper limit stop 27, its effective height protruding from the upper surface of the movable plate 22 can be changed. Since the upper limit stop 27 limits the upward stroke of the movable plate 22 through contact with the upper fixed plate 21, adjusting the protrusion height of the upper limit stop 27 directly changes the highest position that the movable plate 22 can rise to. For example, screwing the upper limit stop 27 downward into the movable plate 22 will lower its top position, allowing the movable plate 22 to rise higher before triggering the limit; conversely, screwing it upward will lower the limit point, restricting the movable plate 22 to stop rising at a lower position. Through the above settings, this embodiment of the application achieves flexible adjustment of the upper limit of the movable plate 22's stroke.

[0064] In some embodiments, the liquid flow control module 100 further includes a lower limit member 28, which is mounted on the lower fixed plate 25 and is used to abut against the movable plate 22 when the movable plate 22 descends to a preset lower height limit, so as to limit the movable plate 22 from continuing to descend.

[0065] Understandably, the lower limit component 28 is used to set the lower limit of the movable plate 22, and it is installed on the upper surface or at a specific position of the lower fixed plate 25. During the descent of the movable plate 22 controlled by the drive element 23, when the movable plate 22 moves to a preset minimum allowable height, i.e., the preset lower height limit, the lower surface or other corresponding part of the movable plate 22 will make physical contact with the lower limit component 28 installed on the lower fixed plate 25. This limiting contact relationship forms a mechanical barrier, preventing the movable plate 22 from continuing to move downwards, even if the drive element 23 is still applying a downward driving force or gravity is present.

[0066] This embodiment of the application provides a reliable travel limit for the downward movement of the lifting mechanism 20 by setting a lower limit member 28, thereby improving the safety and reliability of equipment operation and defining the minimum clearance position or closed state of the pressure plate 10. It effectively prevents the movable plate 22 from descending excessively due to control errors or external forces, and avoids the pressure plate 10 directly impacting the water supply port 202 structure or the bottom of the water tank 201, thus protecting the pressure plate 10, water supply port 202, and related components from damage. Simultaneously, it ensures that the minimum distance between the pressure plate 10 and the water supply port 202 reaches and remains at a preset value.

[0067] In some embodiments, the lower limit member 28 is threadedly connected to the lower fixed plate 25, and the lower fixed plate 25 can adjust its height relative to the lower fixed plate 25 through threaded engagement with the lower fixed plate 25, so as to adjust the preset lower limit of the height of the movable plate 22.

[0068] Understandably, similar to the upper limit member 27, the lower limit member 28 can be an adjusting bolt or a threaded stop, and the lower limit member 28 is installed with the lower fixed plate 25 via a threaded connection. This threaded connection allows the lower limit member 28 to be adjusted in height relative to the lower fixed plate 25. By rotating the lower limit member 28, its effective height protruding upward from the upper surface of the lower fixed plate 25 can be changed. Since the descending movable plate 22 is limited to its lowest position by contacting the top of the lower limit member 28, adjusting the protrusion height of the lower limit member 28 directly changes the lowest position that the movable plate 22 can descend to. For example, screwing the lower limit member 28 downward into the lower fixed plate 25 slightly will lower its top position, allowing the movable plate 22 to descend even lower before triggering the limit, bringing the pressure plate 10 closer to or even closing the water supply port 202; conversely, screwing it upward will raise the limit position, limiting the movable plate 22 to stop descending at a higher position. This embodiment of the application achieves flexible adjustment of the lower limit of the travel of the movable plate 22 through the above settings.

[0069] Please review Figure 1In some embodiments, the center planes A of the upper fixed plate 21, lower fixed plate 25, movable plate 22, and pressure plate 10 perpendicular to the length direction are aligned with each other, and the driving element 23 is located on the center plane of the upper fixed plate 21 perpendicular to the length direction.

[0070] Understandably, the upper fixed plate 21, lower fixed plate 25, movable plate 22, and pressure plate 10 are aligned with each other on their central planes perpendicular to their length. Viewed from the side, the geometric center lines of these plates lie on the same vertical line. That is, the line of action of the driving force also passes through this common central vertical plane. The entire lifting mechanism 20 is roughly symmetrically arranged, ensuring balanced application and transmission of the driving force and minimizing adverse effects such as eccentric loads. When the driving element 23 is centered and acts on the equally centered movable plate 22, the driving force is distributed more evenly, avoiding torque or lateral force on the movable plate 22 and guide shaft 26. The alignment of the plates helps maintain the horizontal posture of the moving parts during lifting, and, in conjunction with the guide shaft 26, effectively prevents tilting and jamming.

[0071] In some embodiments, the guide shaft 26 and the fixing post 24 are each arranged in pairs, and the guide shaft 26 and the fixing post 24 are respectively arranged on both sides of the central plane. The guide shaft 26 and the fixing post 24 on both sides of the central plane are symmetrical to each other, and the fixing post 24 on each side of the central plane is located between the central plane and the corresponding guide shaft 26.

[0072] Please review Figure 1 In a second aspect, embodiments of this application also provide a fruit and vegetable transport device 1000, including a conveyor platform 200 and a liquid flow control module 100 as described in the above embodiments. The conveyor platform 200 is provided with a water tank 201, and a water inlet 202 is provided on the bottom surface of the water tank 201, located at the front end of the water tank 201. The liquid flow control module 100 is installed on the conveyor platform 200, and its pressure plate 10 is located above the water inlet 202. The liquid flow control module 100 is used to adjust the distance between the pressure plate 10 and the water inlet 202 by controlling the lifting and lowering of the pressure plate 10.
