[0001] The embodiment of the present application relates to fruit and vegetable sorting technical field, and particularly relates to a fruit and vegetable conveying device and a fruit and vegetable sorting equipment. BACKGROUND

[0002] In the field of fruit and vegetable sorting and conveying, the conventional conveying device has the technical limitation that the discharge port size is fixed. Due to the large individual difference of fruits and vegetables, a single size of the discharge port is difficult to adapt to different categories or specifications of agricultural products, which often leads to problems such as leakage and accumulation of small fruits and vegetables or jamming and damage of large fruits and vegetables. Although there is a way to adjust the outlet by replacing accessories in the prior art, it has defects such as complicated operation and long downtime, which seriously affects the sorting efficiency, especially in the continuous operation scene. SUMMARY

[0007] Through the above structure, the hopper realizes the size adjustment control of the discharge port through the cooperation of the adjustable baffle and the hopper frame. When different sizes of fruits and vegetables (such as small particle blueberries or larger size strawberries) need to be processed, the operator can slide the baffle along the height direction of the hopper frame to increase or reduce the vertical distance between the bottom end of the baffle and the conveying belt, so as to change the effective flow cross section of the discharge port. The adjustable baffle of the embodiment of the present application enables the fruit and vegetable conveying device to quickly adjust the discharge port according to different fruits and vegetables to meet the corresponding fruit and vegetable conveying requirements.

[0011] Through the above structure, the waist-shaped hole extends along the height direction of the hopper frame to form a vertical guide, the baffle can only slide along the extension direction of the waist-shaped hole and rotate around the axis of the bolt in the case that the bolt is arranged through the through hole and the waist-shaped hole, and the baffle is fixed by the friction force when the nut is tightened.

[0012] Optionally, the fruit and vegetable conveying device further comprises a support, the hopper is mounted on the support, the support comprises two support columns and two blocking columns, the support columns and the blocking columns are arranged along the conveying direction of the conveying belt, one support column and one blocking column are arranged on each side of the conveying direction of the conveying belt, the conveying belt comprises a plurality of support rollers arranged at intervals along the conveying direction, one end of each support roller is connected to one of the support columns, the other end of each support roller is connected to the other support column, each support column is arranged in a gap from the edge of the corresponding side of the conveying belt, each blocking column is connected to the corresponding support column, each blocking column is at least partially located above the belt surface of the conveying belt and forms a running gap with the belt surface of the conveying belt, and the running gap is smaller than the minimum diameter of the fruit and vegetable.

[0013] Through the above structure, the blocking beam of the present application covers the gap on both sides of the conveying belt and limits the fruit and vegetable on the conveying belt, thereby solving the problem that the fruit is easy to fall off on both sides of the inclined conveying belt.

[0014] Optionally, the conveying belt comprises a U-shaped turning section at the end, the blocking column comprises a hook-shaped portion at the end, the hook-shaped portion is provided with an arc surface matched with the U-shaped turning section, the hook-shaped portion is matched and mounted on the U-shaped turning section, and the arc surface forms the running gap with the belt surface of the U-shaped turning section.

[0015] Through the above structure, the U-shaped turning section at the end of the conveying belt and the hook-shaped portion at the end of the blocking beam form a mutually matched structure, and the arc surface design enables the conveying belt to still stably convey the fruit and vegetable when turning. The present application solves the problems of fruit being easily stuck and missing in the traditional conveying belt turning section by geometric structure matching.

[0016] Optionally, the conveying belt comprises:

[0017] The annular belt body comprises at least two belt units arranged in sequence along the conveying direction;

[0018] The connecting assembly is arranged at the abutting end of the two adjacent belt units, and comprises a first chain belt, a second chain belt and a detachable connecting piece. The first chain belt is fixedly arranged at the abutting end of one of the two adjacent belt units and extends along the width direction of the conveying belt. The second chain belt is fixedly arranged at the abutting end of the other of the two adjacent belt units. The first chain belt and the second chain belt are connected together. The detachable connecting piece can be mounted on the first chain belt and the second chain belt respectively and restricts the separation of the first chain belt and the second chain belt.

[0019] Through the above structure, the conveying belt adopts the annular belt body formed by the plurality of belt units connected by the connecting assembly.

[0020] Optionally, the detachable connecting piece is a pin, the first chain belt extends along the width direction of the conveying belt and is provided with a plurality of first chain teeth arranged at intervals, and the second chain belt extends along the width direction of the conveying belt and is provided with a plurality of second chain teeth interlockingly engaged with the first chain teeth.

[0021] Each first chain tooth is provided with a first pin hole perpendicular to the conveying direction, each second chain tooth is provided with a second pin hole coaxial with the first pin hole, and the pin is detachably arranged in the first pin hole and the second pin hole.

[0025] Optionally, the flexible blocking part is a leather piece or a brush.

[0026] Through the above structure, when the flexible blocking part adopts a leather piece, its natural flexibility and wear resistance enable it to deform with the running of the conveying belt. When the pushing structure passes, the leather edge is instantaneously bent due to the pushing force of the pushing structure, and then restores to closely adhere to the belt surface relying on the elasticity of the material, forming a dynamic sealing barrier. When the pushing structure passes, the soft bristles of the brush structure present a directional bent state, and when the fruits and vegetables contact the bristles, resistance is formed due to the reverse force. The bristles bend to make way when the pushing structure passes, and the bristles restore and block when the fruits and vegetables roll back.

[0027] Optionally, a Teflon film is attached to the side wall of the hopper.

[0028] Through the above structure, when the soft fruits (such as blueberries) enter the hopper from the feeding port, the surface of the Teflon film has small friction with the fruits and vegetables, so that when the soft fruits slide along the inclined surface of the hopper under the action of gravity, the adhesion resistance of the contact surface is significantly reduced. When the conveying belt carries the soft fruits with powder, the powder is difficult to adhere to the Teflon film, so that the soft fruits are not easy to drop powder when they hit the inner wall of the hopper during feeding.

[0029] In another aspect, the embodiments of the present application also provide a fruit and vegetable sorting device, which comprises the fruit and vegetable conveying device according to any one of the above.

[0030] The embodiments of the present application can achieve the following technical effects: the hopper realizes the adjustment and control of the size of the discharge port through the cooperation of the adjustable baffle and the hopper frame. When different sizes of fruits and vegetables (such as small particle blueberries or larger size strawberries) need to be processed, the operator can slide the baffle along the height direction of the hopper frame to increase or reduce the vertical distance between the bottom end of the baffle and the conveying belt, thereby changing the effective flow cross section of the discharge port. The adjustable baffle of the embodiments of the present application enables the fruit and vegetable conveying device to quickly adjust the discharge port according to different fruits and vegetables to meet the corresponding fruit and vegetable conveying requirements.

[0040] Unless otherwise defined, all technical and scientific terms used in the present specification have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0041] In a first aspect, the embodiments of the present application provide a fruit and vegetable conveying device, which can be applied to fruit and vegetable processing, sorting and other equipment.

[0042] Please refer to Figure 1 andFigure 2 In some embodiments, the fruit and vegetable conveying device 100 comprises a conveying belt 10 and a hopper 20 arranged obliquely. The conveying belt 10 comprises a plurality of pushing structures 11 arranged on the surface of the conveying belt 10, the plurality of pushing structures 11 are arranged in multiple rows, and each two adjacent pushing structures 11 in each row are arranged at intervals. The arrangement direction of the pushing structures 11 in each row is configured to form a preset angle with the conveying direction of the conveying belt 10. The interval between each two adjacent pushing structures 11 in each row is aligned with one pushing structure 11 in the next row in the conveying direction of the conveying belt 10, and the pushing structure 11 is used to push the fruit and vegetable upward.

[0043] The hopper 20 comprises a flexible blocking part 21, and the hopper 20 is further provided with a hopper bin 24 and a feeding port 25 and a discharging port 26 respectively communicating with the hopper bin 24. The discharging port 26 is arranged above the conveying belt 10, and the flexible blocking part 21 is arranged at the discharging port 26. The flexible blocking part 21 is arranged to extend along the discharging direction of the discharging port 26 and the width direction of the conveying belt 10 respectively and partially adheres to the surface of the conveying belt 10. The flexible blocking part 21 is used to allow the pushing structure 11 to pass through and block the fruit and vegetable rolled back on the conveying belt 10.

[0044] The structural principle of the fruit and vegetable conveying device 100 of the embodiments is that the conveying belt 10 adopts the pushing structures 11 arranged in multiple rows at intervals. The pushing structures 11 in adjacent rows form a relay layout in the conveying direction. When the fruit and vegetable falls from the hopper 20 to the conveying belt 10, if the interval region between the pushing structures 11 in a row is accumulated, the excess fruit and vegetable will naturally fall from the interval region to the corresponding pushing structure 11 in the next row, so as to be distributed to other regions of the conveying belt 10. At the same time, the flexible blocking part 21 arranged at the outlet of the hopper 20 can not only allow the pushing structure 11 to pass through smoothly, but also adhere to the surface to form a barrier, effectively block the fruit and vegetable transported to a high place from rolling back due to gravity, and thus maintain the smoothness of the conveying channel.

[0045] It can be understood that this design realizes the automatic uniform distribution of fruit and vegetable through the staggered arrangement of the pushing structures 11. When the amount of fruit and vegetable in a certain region is too much, the gravity will cause part of the fruit and vegetable to fall through the interval and fall into the carrying region of the pushing structure 11 in the next row, so as to avoid the squeezing damage caused by single-point accumulation. At the same time, the dynamic cooperation of the flexible blocking part 21 and the conveying belt 10 not only does not affect the operation of the equipment, but also solves the problem that the traditional rigid plate is easy to jam fruit and block material, and significantly improves the transportation integrity and efficiency of blueberries, raspberries and other berries.

[0046] In some embodiments, the preset angle formed by the arrangement direction of the pushing structures 11 in each row and the conveying direction of the conveying belt 10 can be 90°. In other embodiments, the designer can set the preset angle to 45° or 60° according to actual experience, which is not limited here.

[0047] In some embodiments, the projection of the interval between two adjacent pushing structures 11 of the same row on a projection plane perpendicular to the conveying direction of the conveying belt 10 is fully covered by the projection of the pushing structures 11 of the adjacent row on the projection plane.

[0048] The projection of the interval between two adjacent pushing structures 11 of the same row on a projection plane perpendicular to the conveying direction of the conveying belt 10 is fully covered by the projection of the pushing structures 11 of the adjacent row on the projection plane. This way, the fruits and vegetables will be effectively received by at least one row of pushing structures 11 regardless of the position of the falling fruits and vegetables from the hopper 20 during the conveying process. When the fruits and vegetables fall from the interval, they will fall into the next row of pushing structures 11 and form a continuous and relayed conveying path.

[0049] It can be understood that even in the extreme case of uneven dropping, the staggered relay arrangement of the pushing structures 11 can still forcibly redistribute the scattered or stacked fruits and vegetables onto the adjacent row of pushing structures 11 through the cooperation of gravity and the movement of the conveying belt 10. This not only avoids the problem of local emptying or overloading caused by continuous and non-interval of the traditional spacer type conveying belt 10, but also significantly reduces the skin damage caused by squeezing and collision during the conveying process by dynamically adjusting the distribution density of the fruits and vegetables, especially for blueberries and other easily damaged berries in large slope and efficient transportation.

[0050] In some embodiments, the projection of the pushing structure 11 on the surface of the conveying belt 10 is arc-shaped, and the pushing structure 11 is recessed towards the opposite direction of the conveying direction of the conveying belt 10.

[0051] The projection of the pushing structure 11 on the surface of the conveying belt 10 is arc-shaped and recessed towards the opposite direction of the conveying direction, which essentially forms a bucket-shaped bearing surface. When the fruits and vegetables (such as blueberries and raspberries) fall into the recessed area, the arc-shaped edge will limit their lateral rolling, and the curvature of the arc-shaped structure will be matched with the inclination angle of the conveying belt 10. For example, when the conveying belt 10 is inclined at an angle of 20°, the curvature radius of the arc-shaped structure can be designed to match 2-3 times the average diameter of the berries, so that the fruits and vegetables naturally gather at the bottom of the arc under the action of the gravitational component, and the force generated by the movement of the conveying belt 10 further pushes them to slide along the arc surface to the bottom of the arc. In this way, the fruits and vegetables are always in the central area of the pushing structure 11, avoiding the side turning or falling caused by the deviation of the center of gravity.

[0052] It can be understood that the arc-shaped pushing structure 11 actively intervenes through its geometric shape, and changes the passive blocking of the traditional flat spacer into active guidance. For example, when the conveying belt 10 accelerates or encounters vibration, the arc-shaped recess can guide the fruits and vegetables to move along the arc surface, significantly reducing the collision and falling caused by inertia.

[0053] In some embodiments, the projection of the pushing structure 11 on the surface of the conveying belt 10 is in an arc shape, and the projection of any two pushing structures 11 belonging to adjacent two rows partially overlaps in the width direction of the conveying belt 10, that is, the two ends of the arc-shaped pushing structure 11 of the next row are higher than the bottom of the arc-shaped pushing structure 11 of the current row.

[0054] It can be understood that, by the above arrangement, the pushing structures 11 of different rows are arranged more compactly, and more pushing structures 11 can be arranged on the same area of the conveying belt 10, so that more fruits and vegetables can be carried, and the conveying efficiency is improved.

[0055] In other embodiments, the projection of the pushing structure 11 on the surface of the conveying belt 10 can also be in a rectangular shape or the like, as long as the pushing requirement of the fruits and vegetables during conveying is met, and the specific shape of the pushing structure 11 can be set according to experience, which is not limited here.

[0056] In the related art, the discharge port 26 of the hopper 20 of the fruit and vegetable conveying device 100 cannot be flexibly adjusted in size, which makes it difficult to adapt to fruits and vegetables of different sizes and cannot adjust the discharge amount of the hopper 20.

[0057] In a second aspect, to solve the above problems, please refer to Figures 1 to 3 The present application provides another fruit and vegetable conveying device 100, which comprises an inclined conveying belt 10 and a hopper 20.

[0058] The conveying belt 10 comprises a plurality of pushing structures 11 arranged on the surface of the conveying belt 10. The hopper 20 comprises a hopper frame 22, a baffle 23, and a flexible blocking part 21. The hopper 20 is also provided with a hopper chamber 24, and a feeding port 25 and a discharge port 26 respectively communicating with the hopper chamber 24. The discharge port 26 is arranged above the conveying belt 10. The end of the hopper frame 22 is connected to the flexible blocking part 21. The baffle 23 is detachably mounted on the hopper frame 22 and cooperates with the hopper frame 22 to form the hopper chamber 24, the feeding port 25 and the discharge port 26 of the hopper 20. The baffle 23 can be adjusted in position relative to the hopper frame 22 to adjust the size of the discharge port 26. The flexible blocking part 21 extends and is arranged along the discharge direction of the discharge port 26 and the width direction of the conveying belt 10, and partially adheres to the surface of the conveying belt 10. The flexible blocking part 21 is used to allow the pushing structure 11 to pass through and block the rolled back fruits and vegetables on the conveying belt 10.

[0059] The structural principle of the fruit and vegetable conveying device 100 of the present application is that the hopper 20 realizes the size adjustment control of the discharge port 26 through the cooperation of the adjustable baffle 23 and the hopper frame 22. When different sizes of fruits and vegetables (such as small particle blueberries or larger size strawberries) need to be processed, the operator can slide the baffle 23 along the height direction of the hopper frame 22 to increase or decrease the vertical distance between the bottom end of the baffle 23 and the conveying belt 10, so as to change the effective flow cross section of the discharge port 26.

[0060] It can be understood that the adjustable baffle 23 enables the fruit and vegetable conveying device 100 to quickly adjust the discharge port 26 according to different fruits and vegetables, so as to meet the conveying requirements of the corresponding fruits and vegetables. For example, when processing soft berries with high maturity, reducing the discharge port 26 can reduce the amount of material falling per unit time, so as to avoid the squeezing of the material on the conveying belt 10; when processing high-hardness fruits and vegetables, increasing the discharge port 26 can improve the conveying efficiency.

[0061] In some embodiments, the baffle 23 can slide relative to the bucket frame 22 in the height direction, the bucket frame 22 is provided with a waist-shaped hole 223 extending in the height direction, the baffle 23 is provided with a through hole 231 aligned with the waist-shaped hole 223, and the hopper 20 further includes a bolt and a nut. The nut is connected with the bolt, and the nut is used to limit the sliding of the baffle 23 relative to the bucket frame 22 when tightened, and to release the sliding limitation of the baffle 23 relative to the bucket frame 22 when loosened.

[0062] It can be understood that the waist-shaped hole 223 extends in the height direction of the bucket frame 22 to form a vertical guide, and the baffle 23 can only slide in the extension direction of the waist-shaped hole 223 and rotate around the axis of the bolt when the bolt passes through the through hole 231 and the waist-shaped hole 223, and is fixed by friction when the nut is tightened.

[0063] In some embodiments, the bucket frame 22 is shovel-shaped, and the bucket frame 22 includes an inclined plate 221 and side plates 222 located on both sides of the inclined plate 221. The inclined plate 221 and the baffle 23 are oppositely arranged and extend obliquely to the belt surface of the conveying belt 10, the baffle 23 is slidably installed between the two side plates 222, and the inclined plate 221, the side plates 222 and the baffle 23 enclose the hopper 20, the feeding port 25 and the discharge port 26. The flexible blocking part 21 is installed at the end of the inclined plate 221, the inclined plate 221 forms a steep slope, and the fruits and vegetables falling on the inclined plate 221 can slide gently, and the flexible blocking part 21 can absorb the impact force of the fruits and vegetables, and the fruits and vegetables falling from the discharge port 26 are buffered by the flexible blocking part 21 and then transition to the belt surface of the conveying belt 10.

[0064] It can be understood that the design of the inclined plate 221 of the bucket frame 22 of the embodiment of the present application avoids damage to the fruits and vegetables caused by excessive impact force of the falling material, thereby ensuring the quality of the fruits and vegetables.

[0065] Please refer to Figure 1In some embodiments, the fruit and vegetable conveying device 100 further comprises a support frame 30, the hopper 20 is mounted on the support frame 30, the support frame 30 comprises two support beams 31 and two blocking beams 32, the support beams 31 and the blocking beams 32 are arranged along the conveying direction of the conveying belt 10, each side of the conveying belt 10 is provided with a support beam 31 and a blocking beam 32, the conveying belt 10 comprises a plurality of support rollers arranged at intervals along the conveying direction, one end of each support roller is connected to one of the support beams 31, the other end of each support roller is connected to the other support beam 31, each support beam 31 is arranged with a gap to the corresponding side edge of the conveying belt 10, each blocking beam 32 is connected to the corresponding support beam 31, each blocking beam 32 is at least partially located above the conveying belt 10 and forms a running gap with the conveying belt 10, the running gap is smaller than the minimum diameter of the fruit and vegetable.

[0066] The support beams 31 are the main load-bearing structure of the conveying belt 10, extending along the conveying direction and rigidly connected to the support rollers arranged at intervals, ensuring that the conveying belt 10 still maintains stable planar support under high load working conditions. For example, when the conveying belt 10 is running at a 20° inclination with a full load of blueberries, the equidistant arrangement of the support rollers can disperse the local pressure of the belt surface to the two side support beams 31, avoiding the problem of belt surface collapse. The blocking beams 32 are laterally fixed to the support beams 31, and the running gap between the bottom end of the blocking beams 32 and the belt surface of the conveying belt 10 is smaller than the minimum diameter of the fruit and vegetable (e.g. blueberries), so that the berries will be blocked by the bottom of the blocking beams 32 and remain on the conveying belt 10 even if they are shifted outward due to inertia, until they are re-conveyed to a higher position by the pushing structure 11.

[0067] It can be understood that the embodiments of the present application solve the problem of fruit falling off the sides of the inclined conveying belt 10 by covering the gaps on both sides of the conveying belt 10 with the blocking beams 32 and limiting the fruit and vegetables on the conveying belt 10. For example, when the fruit and vegetables are temporarily unstable due to acceleration or vibration of the conveying belt 10, the running gap of the blocking beams 32 can allow the conveying belt 10 to run, but can block the large gap between the support beams 31 and the edge of the conveying belt 10, preventing small-sized berries from rolling off the edge of the belt surface. Exemplarily, the blocking beams 32 can be made of smooth plastic structural parts, such as Teflon blocking beams 32, which use the smooth surface of the Teflon blocking beams 32 to avoid friction and damage to the skin of the fruit and vegetables.

[0068] Please refer to Figure 4 In some embodiments, the conveying belt 10 comprises a U-shaped turning section 12 at the end, the blocking beam 32 comprises a hook-shaped portion 321 at the end, the hook-shaped portion 321 is inwardly provided with an arc surface adapted to the U-shaped turning section 12, the hook-shaped portion 321 is adapted to be mounted on the U-shaped turning section 12, and the arc surface forms a running gap with the belt surface of the U-shaped turning section 12.

[0069] The U-shaped turning section 12 at the end of the conveying belt 10 and the hook-shaped portion 321 at the end of the blocking beam 32 form a mutually adaptive structure, and the curved surface design enables the conveying belt 10 to maintain stable transportation of fruits and vegetables during turning. For example, when the conveying belt 10 enters a horizontal section after completing uphill transportation, the curvature radius of the U-shaped turning section 12 is consistent with the curved surface of the hook-shaped portion 321, and the two are matched and positioned with each other to form a continuous and smooth transition path. At this time, the curved surface of the hook-shaped portion 321 and the running gap between the U-shaped turning section 12 enable the conveying belt 10 to freely turn while preventing small-particle berries such as blueberries from falling through the gap at the turning point.

[0070] It can be understood that the embodiments of the present application solve the problems of fruit jamming and leakage at the turning section of the conventional conveying belt 10 by geometric structure adaptation. At the same time, the wrapping and clamping design of the hook-shaped portion 321 on the U-shaped turning section 12 can effectively disperse stress concentration during turning, thereby prolonging the service life of the conveying belt 10. When the blocking beam 32 is made of Teflon, its self-lubricating property can further reduce friction noise during turning.

[0071] Please refer to Figure 5 In some embodiments, the conveying belt 10 includes a ring-shaped belt body 13 and a connecting assembly 14. The ring-shaped belt body 13 includes at least two belt units 131 arranged in sequence along the conveying direction. The connecting assembly 14 is arranged at the abutting end of the adjacent two belt units 131, and the connecting assembly 14 includes a first chain belt 1411, a second chain belt 1412, and a detachable connecting piece 142. The first chain belt 1411 is fixedly arranged at the abutting end of one of the adjacent two belt units 131 and extends along the width direction of the conveying belt. The second chain belt 1412 is fixedly arranged at the abutting end of the other of the adjacent two belt units 131. The first chain belt 1411 and the second chain belt 1412 are connected in cooperation. The detachable connecting piece 142 can be respectively mounted on the first chain belt 1411 and the second chain belt 1412 and limit the mutual separation of the first chain belt 1411 and the second chain belt 1412.

[0072] It can be understood that the conveying belt 10 adopts the ring-shaped belt body 13 which is spliced by a plurality of belt units 131 through the connecting assembly 14, and the modular design significantly improves the equipment maintenance efficiency. For example, when a certain belt unit 131 is worn or damaged due to long-term use, the damaged belt unit 131 can be replaced individually by separating the corresponding two chain belts through the detachable connecting piece 142, without the need to disassemble the entire conveying belt 10. This not only reduces downtime, but also significantly reduces maintenance costs. At the same time, the design that the first chain belt 1411 and the second chain belt 1412 extend along the width direction of the conveying belt 10 enables the stress distribution at the connection to be more uniform.

[0073] In some embodiments, the detachable connecting member 142 is a pin, the first chain belt 1411 is arranged along the width direction of the conveying belt and is provided with a plurality of first chain teeth 14111 arranged at intervals, and the second chain belt 1412 is arranged along the width direction of the conveying belt and is provided with a plurality of second chain teeth 14121 arranged at intervals and engaged with the first chain teeth 14111.

[0074] Each first chain tooth 14111 is provided with a first pin hole perpendicular to the conveying direction, each second chain tooth 14121 is provided with a second pin hole coaxial with the first pin hole, and the pin is detachably arranged in the first pin hole and the second pin hole opposite to each other.

[0075] It can be understood that the detachable connecting member 142 is a pin, which is connected with the two chain belts, and the adjacent belt units 131 are quickly connected by the interlocking of the first chain teeth 14111 and the second chain teeth 14121. For example, when installing the belt unit 131, the operator only needs to align and embed the tooth grooves of the first chain teeth 14111 and the second chain teeth 14121, and then insert the pin transversely into the opposite first pin hole and second pin hole, so as to form a multi-point rigid connection in the width direction of the conveying belt 10.

[0076] In other embodiments, the detachable connecting member 142 can also be a zipper, the end of any one of the first chain teeth 14111 and the second chain teeth 14121 is provided with a transversely extending protruding structure (for example, a transversely protruding part of a T-shaped structure), and the tooth groove formed by the interval arrangement of the other one is adapted to the shape of the protruding structure, so as to effectively prevent the first chain teeth 14111 and the second chain teeth 14121 from disengaging after being engaged. The zipper is connected with the first chain belt 1411 and the second chain belt 1412 respectively and can slide relative to the first chain belt 1411 and the second chain belt 1412. For example, during the sliding of the zipper in a first direction along the length of the two chain belts, the first chain teeth 14111 can be embedded in the tooth groove formed by the interval arrangement of the second chain teeth 14121, and the second chain teeth 14121 can be embedded in the tooth groove formed by the interval arrangement of the first chain teeth 14111; during the sliding of the zipper in a second direction (opposite to the first direction) along the length of the chain belt, the first chain teeth 14111 and the second chain teeth 14121 can be respectively pushed in the height direction of the two chain belts, so that the protruding structure is separated from the tooth groove, and the first chain teeth 14111 and the second chain teeth 14121 are disengaged. In other embodiments, the designer can set the specific form of the chain belt and the detachable connecting member 142 according to experience, which is not limited here.

[0077] Please refer to Figure 1 In some embodiments, the support 30 further comprises at least two groups of bottom support assemblies 33, each of which is connected with two support beams 31, and the at least two groups of bottom support assemblies 33 are arranged at intervals in the length direction of the support beam 31.

[0078] It can be understood that the embodiments of the present application provide multiple sets of support assemblies 33 for better supporting the hopper 20 and the support beams 31, thereby ensuring the stability of the overall structure.

[0079] In some embodiments, the support assembly 33 comprises vertical support rods 331 and longitudinal support rods 332, the vertical support rods 331 are arranged in pairs, and each vertical support rod 331 is connected to a corresponding support beam 31 at an end away from the ground, and each longitudinal support rod 332 is connected to a corresponding vertical support rod 331 at each end.

[0080] It can be understood that each support assembly 33 of the embodiments of the present application supports the support beam 31 through the vertical support rod 331, and the longitudinal support rod 332 is rigidly connected to the two vertical support rods 331 in the pair respectively, so that the two vertical support rods 331 in the pair are kept fixed to each other. Further, the vertical support rod 34 is rigidly connected to the longitudinal support rod 332 in each support assembly 33, so that each support assembly 33 is kept fixed to each other.

[0081] In some embodiments, part of the support assembly 33 further comprises an auxiliary support rod 333, one end of the auxiliary support rod 333 is connected to one of the vertical support rods 331, and the other end of the auxiliary support rod 333 is connected to the longitudinal support rod 332, and the vertical support rod 331, the longitudinal support rod 332 and the auxiliary support rod 333 together form a stable triangular structure.

[0082] It can be understood that the support assembly 33 of the embodiments of the present application is configured with the auxiliary support rod 333, which is rigidly connected to the vertical support rod 331 and the longitudinal support rod 332 respectively, to further ensure the stability of the overall structure.

[0083] In some embodiments, the flexible blocking part 21 is a leather piece or a brush.

[0084] It can be understood that when the flexible blocking part 21 is a leather piece, its natural flexibility and wear resistance enable it to deform with the operation of the conveying belt 10, and when the pushing material structure 11 passes, the leather edge is instantaneously bent due to the pushing force of the pushing material structure 11, and then restores to closely adhere to the belt surface relying on the material elasticity, forming a dynamic sealing barrier. For example, in the process of transporting blueberries, the deformation of the leather piece can avoid rigid collision with the pushing material structure 11, which can prevent back rolling and will not cause damage to the skin of fruits and vegetables due to excessive friction. When a brush structure is used, the densely arranged soft bristles present a directional lodging state when the pushing material structure 11 passes, and when the fruits and vegetables contact the bristles, resistance is formed due to the reverse force. The bristles yield to make way when the pushing material structure 11 passes, and the bristles recover and block when the fruits and vegetables back roll.

[0085] In some embodiments, the side wall of the hopper 24 is provided with a Teflon film.

[0086] It can be understood that when the berries (such as blueberries) enter the hopper 24 from the feed port 25, the surface of the Teflon film has less friction with the fruits and vegetables, so that when the berries slide along the inclined surface of the hopper 24 under the action of gravity, the adhesion resistance of the contact surface is significantly reduced. Further, when the berries carrying fruit powder are transported, it is difficult for the fruit powder to adhere to the Teflon film, so that the berries are not easy to drop powder when they hit the inner wall of the hopper 24 during feeding.

[0087] Please refer to Figure 1 In a third aspect, the embodiments of the present application also provide a fruit and vegetable sorting device, which comprises the fruit and vegetable conveying device 100 according to any one of the above embodiments.

[0088] The fruit and vegetable conveying device 100 according to the above embodiments can be applied to the feeding end of the fruit and vegetable sorting device according to the embodiments of the present application, or a process that needs to transport fruits and vegetables.

[0089] It can be understood that the fruit and vegetable sorting device according to the embodiments of the present application avoids the problem of affecting the quality of fruits and vegetables caused by accumulation and extrusion during the transportation of fruits and vegetables by using the fruit and vegetable conveying device 100 according to the above embodiments.
