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 conveying 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, tomatoes, and pineapples. 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 conveying mechanisms, which are used to drive the fruits and vegetables to move between various mechanisms in the fruit and vegetable sorting device. The fruit and vegetable conveying mechanism may include sprockets and chains driven by electric motors. Generally, the torque generated by the electric motor during operation is relatively large, so a torque arm needs to be set between the electric motor and the frame of the fruit and vegetable sorting device to transmit the torque of the electric motor to the frame.

[0004] However, the chain exerts significant pressure on the motor, which may cause the motor to shift relative to the frame, necessitating adjustments to the motor's position relative to the frame. However, during the movement of the motor relative to the frame, the torque arm may become stuck relative to the frame. Utility Model Content

[0005] The present invention aims to provide a fruit and vegetable conveying mechanism and a fruit and vegetable sorting device to solve the technical problem in the prior art that the torque arm may get stuck relative to the frame during the movement of the motor relative to the frame.

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

[0007] One embodiment of this utility model provides a fruit and vegetable conveying mechanism, comprising:

[0008] frame;

[0009] Mounting bracket, which is detachably mounted to the frame;

[0010] The drive component is mounted on the mounting bracket;

[0011] Torque arm, which is mounted between the drive assembly and the mounting bracket;

[0012] An adjustment component is installed between the mounting bracket and the frame, and the adjustment component is used to adjust the relative position of the mounting bracket and the frame.

[0013] With the above structure, the mounting bracket is detachably mounted on the frame, and the torque arm is mounted between the drive assembly and the mounting bracket. The mounting bracket is located between the frame and the drive assembly. When the drive assembly is subjected to a large torque, the torque of the drive assembly can be transmitted to the frame through the torque arm and the mounting bracket, and the drive assembly can drive the mounting bracket to move relative to the frame.

[0014] When adjusting the position of the drive assembly relative to the rack, the user can first remove the mounting bracket from the rack, then adjust the relative position of the mounting bracket and the rack by adjusting the assembly so that the mounting bracket is in the appropriate position on the rack, and then fix the mounting bracket to the rack. During this process, the mounting bracket, drive assembly and torque arm all move synchronously, reducing the possibility of the torque arm getting stuck.

[0015] In some embodiments, the mounting bracket includes a first support bar and a second support bar arranged parallel to each other, the first support bar and the second support bar being at the same height;

[0016] The drive assembly includes a drive component and a rotating shaft component. The drive component is mounted on the mounting bracket. One end of the rotating shaft component is rotatably connected to the first support bar, and the other opposite end of the rotating shaft component is rotatably connected to the second support bar. The drive component is used to drive the rotating shaft component to rotate relative to the mounting bracket.

[0017] With the above structure, the first support bar and the second support bar can support the rotating shaft component at two points, reducing the degree of radial sway of the rotating shaft component and improving the stability of the drive assembly during operation.

[0018] In some embodiments, in the extending direction of the rotating shaft component, the driving component, the first support bar, and the second support bar are arranged sequentially, and the torque arm is located between the driving component and the first support bar.

[0019] With the above structure, the torque arm is located between the drive component and the first support bar, so that the distance between the torque arm and the drive component is closer, and the torque arm can transmit the torque of the drive component to the mounting bracket to a greater extent, thereby improving the stability of the drive component during operation.

[0020] In some embodiments, the mounting bracket includes a side protrusion plate located on the side of the first support bar facing away from the second support bar, and the side protrusion plate is parallel to the horizontal plane;

[0021] The torque arm includes a vertical connecting plate and a horizontal connecting plate. The upper end of the vertical connecting plate is sleeved on the rotating shaft component, and the horizontal connecting plate is connected to the lower end of the vertical connecting plate. The horizontal connecting plate faces the side of the vertical connecting plate that is away from the driving component, and the horizontal connecting plate is fixed to the side protrusion plate.

[0022] With the above structure, the horizontal connecting plate can be parallel to the horizontal plane and fixed to the side protrusion plate. In the horizontal direction, the contact area between the horizontal connecting plate and the side protrusion plate is larger, so that the torque arm can transmit the torque to the side protrusion plate to a greater extent through the horizontal connecting plate, which further improves the stability of the drive assembly.

[0023] In some embodiments, the adjustment assembly includes a guide rod and a locking element, one end of the guide rod being fixedly connected to the frame, and the other end of the guide rod being detachably connected to the mounting bracket via the locking element;

[0024] When the locking member is connected to the mounting bracket, the mounting bracket is fixed relative to the frame; when the locking member is removed from the mounting bracket, the mounting bracket can move relative to the frame along the guide rod.

[0025] With the above structure, when the locking member is removed from the mounting bracket, the mounting bracket can move along the guide rod relative to the frame, and the guide rod can guide the mounting bracket; in addition, the relative position of the mounting bracket and the frame can be precisely adjusted by marking the scale on the guide rod.

[0026] In some embodiments, the number of adjustment components is two, and the two adjustment components are respectively located on opposite sides of the mounting bracket.

[0027] With the above structure, the two adjustment components are located on opposite sides of the mounting bracket. When the locking member is fixed relative to the mounting bracket, the two adjustment components can support the mounting bracket more stably, improving the stability of the mounting bracket relative to the frame. When the locking member is removed from the mounting bracket, the two guide rods can guide the mounting bracket simultaneously.

[0028] In some embodiments, the frame has a strip-shaped mounting slot, and the mounting bracket further includes a fixing member, which is detachably installed in the strip-shaped mounting slot; when the fixing member is detached from the frame, the mounting bracket can move along the strip-shaped mounting slot.

[0029] With the above structure, after the fastener is disassembled from the frame, the mounting bracket can be moved to the appropriate position along the strip mounting groove, and then the fastener is fixed in the strip mounting groove, so that the mounting bracket is fixed relative to the frame, simplifying the disassembly and assembly process between the mounting bracket and the frame.

[0030] In some embodiments, the fruit and vegetable conveying mechanism further includes a tensioning assembly, the tensioning assembly comprising:

[0031] A fixing bracket, wherein the fixing bracket is mounted on the mounting bracket;

[0032] A rotating bracket, the upper end of which is rotatably connected to the fixed bracket, the lower end of which extends out of the fixed bracket, and the fixed bracket including a clamping sidewall;

[0033] Tensioning component, the tensioning component is installed at the lower end of the rotating bracket, the tensioning component includes an abutting arc surface;

[0034] An elastic abutment component includes a guide, a fastener, an adjusting member, and a spring. One end of the guide passes sequentially through the rotating bracket and the clamping sidewall, and the other opposite end of the guide is connected to the mounting bracket. The fastener and the adjusting member are respectively connected to the two ends of the guide. The fastener and the rotating bracket are respectively located on opposite sides of the clamping sidewall. The spring is sleeved on the guide and located between the rotating bracket and the adjusting member. The clamping sidewall and the spring clamp the rotating bracket.

[0035] The abutting arc surface faces the side of the rotating bracket, and the elastic abutting component is located on the opposite side of the rotating bracket;

[0036] The fastener is fixed to the clamping sidewall, and the adjusting member can move or be fixed relative to the guide member.

[0037] With the above structure, one end of the elastic abutment component is connected to the rotating bracket, and the other opposite end can be connected to the mounting bracket. The elastic abutment component undergoes elastic deformation, so that it can provide elastic force to the rotating bracket. The abutment arc surface faces the rotating bracket, and the elastic abutment component is located on the other opposite side of the rotating bracket. The abutment arc surface can abut against the conveyor chain. Thus, the elastic abutment component can support the rotating bracket, so that the rotating bracket can provide tension to the conveyor chain through the abutment arc surface of the tensioning component, thereby reducing the possibility of the conveyor chain becoming loose during operation.

[0038] Furthermore, when the tension provided by the contact arc to the conveyor chain is large, the elastic contact component needs to provide greater elasticity to the rotating bracket. The elastic deformation of the elastic contact component is large, and the rotation amplitude of the rotating bracket relative to the fixed bracket is large. The tensioning component can contract into the space enclosed by the conveyor chain to reduce the tension required by the conveyor chain. Similarly, when the tension provided by the contact arc to the conveyor chain is small, the tensioning component can expand outward from the space enclosed by the conveyor chain to increase the tension required by the conveyor chain. Thus, the chain tensioning component can adapt to the tension of the chain to reduce the possibility of the conveyor chain loosening.

[0039] During operation, the tensioning assembly is continuously subjected to pressure from the conveyor chain, which may cause it to shift relative to the frame. The adjusting member can move or be fixed relative to the guide. When the tensioning assembly shifts relative to the frame, the adjusting member can be moved a certain distance relative to the guide to reset the tensioning assembly relative to the frame, and then the adjusting member can be fixed to the guide.

[0040] In some embodiments, the fruit and vegetable conveying mechanism further includes a drive sprocket, a driven sprocket, and a conveying chain. The drive sprocket is mounted on the drive assembly, which drives the drive sprocket to rotate. The conveying chain is mounted between the drive sprocket and the driven sprocket, and the abutting arc surface abuts against the conveying chain.

[0041] With the above structure, multiple fruit cups can be installed on the conveyor chain. The fruit cups can be used to hold fruits and vegetables, and the drive component can drive the conveyor chain to move, thereby moving the fruits and vegetables.

[0042] Another embodiment of this utility model provides a fruit and vegetable sorting device, including the fruit and vegetable conveying mechanism in any of the above embodiments.

[0043] Compared with the prior art, the mounting bracket is detachably mounted on the frame, and the torque arm is mounted between the drive assembly and the mounting bracket. The mounting bracket is located between the frame and the drive assembly. When the drive assembly is subjected to a large torque, the torque of the drive assembly can be transmitted to the frame through the torque arm and the mounting bracket, and the drive assembly can drive the mounting bracket to move relative to the frame.

[0044] When adjusting the position of the drive assembly relative to the rack, the user can first remove the mounting bracket from the rack, then adjust the relative position of the mounting bracket and the rack by adjusting the assembly so that the mounting bracket is in the appropriate position on the rack, and then fix the mounting bracket to the rack. During this process, the mounting bracket, drive assembly and torque arm all move synchronously, reducing the possibility of the torque arm getting stuck. Attached Figure Description

The drive assembly 30 can drive the mounting bracket 20 to move relative to the frame 10.

[0060] When the user adjusts the position of the drive assembly 30 relative to the frame 10, the mounting bracket 20 can be removed from the frame 10 first. Then, the relative position of the mounting bracket 20 and the frame 10 can be adjusted by adjusting the component 50 so that the mounting bracket 20 is in an appropriate position on the frame 10. Then, the mounting bracket 20 can be fixed to the frame 10. During this process, the mounting bracket 20, the drive assembly 30 and the torque arm 40 all move synchronously, reducing the possibility of the torque arm 40 getting stuck.

[0061] Specifically, in this embodiment, the frame 10 may include a hollow structure formed by splicing steel plates and steel bars, and the mounting bracket 20 may include a structure of multiple steel bars spliced ​​together.

The upper end of the torque arm 40 may be connected to the housing of the drive assembly 30 by screw connection. The upper end of the torque arm 40 may have multiple threaded holes. The threaded holes at the upper end of the torque arm 40 are arranged around the rotating shaft of the drive assembly 30. The lower end of the torque arm 40 may also be fixed to the mounting bracket 20 by screw connection.

[0063] There can be two adjusting components 50, located on opposite sides of the mounting bracket 20. Each adjusting component 50 may include bolts and nuts. The bolts of the adjusting components 50 can be sequentially inserted into the frame 10 and the mounting bracket 20, with the bolts extending parallel to the horizontal plane. When the frame 10 and the mounting bracket 20 are fixed relative to each other, the bolt nut and one nut can hold one steel bar of the frame 10, and the other two nuts on the bolt can hold one steel bar of the mounting bracket 20. When the mounting bracket 20 is disassembled relative to the frame 10, the two nuts on the bolt can loosen one steel bar of the mounting bracket 20.

[0064] In other embodiments, the frame 10 and the mounting bracket 20 may each include other structures, such as a hollow box structure; the adjustment assembly 50 may also include other structures, such as a lead screw and a slider disposed on the lead screw.

[0065] In some embodiments, the mounting bracket 20 includes a first support bar 22 and a second support bar 24 arranged parallel to each other, with the first support bar 22 and the second support bar 24 located at the same height.

[0066] The drive assembly 30 includes a drive component 32 and a rotating shaft component 34. The drive component 32 is mounted on the mounting bracket 20. One end of the rotating shaft component 34 is rotatably connected to the first support bar 22, and the other opposite end of the rotating shaft component 34 is rotatably connected to the second support bar 24. The drive component 32 is used to drive the rotating shaft component 34 to rotate relative to the mounting bracket 20.

[0067] With the above structure, the first support bar 22 and the second support bar 24 can support the rotating shaft component 34 at two points, reducing the degree of radial sway of the rotating shaft component 34 and improving the stability of the drive assembly 30 during operation.

[0068] Specifically, both the first support bar 22 and the second support bar 24 may include hollow steel bar structures, and the first support bar 22 and the second support bar 24 may be located on the upper side of the mounting bracket 20. The driving component 32 may include an electric motor; a connecting block may be provided between the rotating shaft component 34 and the first support bar 22, and between the rotating shaft component 34 and the second support bar 24. The lower end of the connecting block may be fixed to the first support bar 22 or the second support bar 24 with screws, and the connecting block and the rotating shaft component 34 may be rotatably connected by a bearing connection.

[0069] In some embodiments, in the extending direction of the rotating shaft component 34, the driving component 32, the first support bar 22 and the second support bar 24 are arranged in sequence, and the torque arm 40 is located between the driving component 32 and the first support bar 22.

[0070] With the above structure, the torque arm 40 is located between the drive component 32 and the first support bar 22, so that the distance between the torque arm 40 and the drive component 32 is closer, and the torque arm 40 can transmit the torque of the drive component 32 to the mounting bracket 20 to a greater extent, thereby improving the stability of the drive component 32 when it is working.

[0073] The torque arm 40 includes a vertical connecting plate 42 and a horizontal connecting plate 44. The upper end of the vertical connecting plate 42 is sleeved on the rotating shaft component 34, and the horizontal connecting plate 44 is connected to the lower end of the vertical connecting plate 42. The horizontal connecting plate 44 faces the side of the vertical connecting plate 42 away from the driving component 32 and is fixed to the side protrusion plate 26.

[0074] With the above structure, the horizontal connecting plate 44 can be parallel to the horizontal plane. The horizontal connecting plate 44 is fixed to the side protrusion plate 26. In the horizontal direction, the contact area between the horizontal connecting plate 44 and the side protrusion plate 26 is larger, so that the torque arm 40 can transmit the torque to the side protrusion plate 26 to a greater extent through the horizontal connecting plate 44, which further improves the stability of the drive assembly 30.

[0075] Specifically, in this embodiment, the vertical connecting plate 42 may include a steel plate structure perpendicular to the horizontal plane; the width of the vertical connecting plate 42 may first increase and then decrease from top to bottom. The horizontal connecting plate 44 may include a rectangular steel plate parallel to the horizontal plane, and the side protrusion plate 26 may also include a rectangular steel plate parallel to the horizontal plane. The lower side of the horizontal connecting plate 44 is attached to the upper side of the side protrusion plate 26.

[0082] With the above structure, the two adjustment components 50 are located on opposite sides of the mounting bracket 20. When the locking member 54 is fixed relative to the mounting bracket 20, the two adjustment components 50 can support the mounting bracket 20 more stably, improving the stability of the mounting bracket 20 relative to the frame 10. When the locking member 54 is removed from the mounting bracket 20, the two guide rods 52 can guide the mounting bracket 20 simultaneously.

[0083] Specifically, the two guide rods 52 are parallel to each other, and the direction from one adjustment component 50 to the other adjustment component 50 is perpendicular to the extension direction of the guide rod 52.

[0084] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the frame 10 has a strip-shaped mounting groove 102, and the mounting bracket 20 also includes a fixing member 28, which is detachably installed in the strip-shaped mounting groove 102; when the fixing member 28 is removed from the frame 10, the mounting bracket 20 can move along the strip-shaped mounting groove 102.

[0085] With the above structure, after the fastener 28 is disassembled relative to the frame 10, the mounting bracket 20 can be moved to a suitable position along the strip mounting groove 102, and then the fastener 28 is fixed in the strip mounting groove 102, so that the mounting bracket 20 is fixed relative to the frame 10, simplifying the disassembly and assembly process between the mounting bracket 20 and the frame 10.

[0086] Specifically, the strip mounting groove 102 is a long, waist-shaped through groove, and the fastener 28 may include bolts; two strip through grooves may be opened on each of the opposite sides of the frame 10, and a corresponding fastener 28 may be installed in each strip through groove.

[0087] The fastener 28 may include threaded fasteners, such as screws or bolts, and the fastener 28 may pass through the strip mounting groove 102 and the strip through groove on the frame 10.

[0088] Please refer to Figure 4 , Figure 5, Figure 6 and Figure 7 In some embodiments, the fruit and vegetable conveying mechanism 100 further includes a tensioning assembly 60, which includes a fixed bracket 62, a rotating bracket 64, a tensioning component 66, and an elastic abutment component 68; the fixed bracket 62 is mounted on the mounting bracket 20; the rotating bracket 64 is rotatably connected to the fixed bracket 62; the tensioning component 66 is connected to the rotating bracket 64, and the tensioning component 66 includes an abutment arc surface 662.

[0089] One end of the elastic abutment member 68 is connected to the rotating bracket 64, and the other opposite end of the elastic abutment member 68 is connected to the mounting bracket 20; the elastic abutment member 68 undergoes elastic deformation, and the elastic abutment member 68 and the fixed bracket 62 clamp the rotating bracket 64; the abutment arc surface 662 faces the side of the rotating bracket 64, and the elastic abutment member 68 is located on the other opposite side of the rotating bracket 64.

[0090] The elastic abutment component 68 includes a guide 682, a fastener 684, an adjusting component 686, and a spring 688. One end of the guide 682 passes through the rotating bracket 64 and the clamping sidewall 622 in sequence, and the other end of the guide 682 is connected to the mounting bracket 20. The fastener 684 and the adjusting component 686 are respectively connected to the two ends of the guide 682. The fastener 684 and the rotating bracket 64 are respectively located on opposite sides of the clamping sidewall 622. The spring 688 is sleeved on the guide 682 and is located between the rotating bracket 64 and the adjusting component 686. The clamping sidewall 622 and the spring 688 clamp the rotating bracket 64.

[0091] Fastener 684 is fixed to clamping sidewall 622, and adjusting member 686 can move or be fixed relative to guide member 682.

[0092] With the above structure, one end of the elastic abutment member 68 is connected to the rotating bracket 64, and the other opposite end can be connected to the mounting bracket 20. The elastic abutment member 68 undergoes elastic deformation so that it can provide elastic force to the rotating bracket 64. The abutment arc surface 662 faces the rotating bracket 64 on one side, and the elastic abutment member 68 is located on the other opposite side of the rotating bracket 64. The abutment arc surface 662 can abut against the conveyor chain 80. Thus, the elastic abutment member 68 can support the rotating bracket 64, so that the rotating bracket 64 can provide tension to the conveyor chain 80 through the abutment arc surface 662 of the tensioning member 66, thereby reducing the possibility of the conveyor chain 80 becoming loose during operation.

[0093] Furthermore, when the tension provided by the abutting arc surface 662 to the conveyor chain 80 is large, the elastic abutting component 68 needs to provide greater elastic force to the rotating bracket 64. The elastic deformation of the elastic abutting component 68 is large, and the rotation amplitude of the rotating bracket 64 relative to the fixed bracket 62 is large. The tensioning component 66 can contract into the space enclosed by the conveyor chain 80 to reduce the tension required by the conveyor chain 80. Similarly, when the tension provided by the abutting arc surface 662 to the conveyor chain 80 is small, the tensioning component 66 can expand outwards from the space enclosed by the conveyor chain 80 to increase the tension required by the conveyor chain 80. Thus, the chain tensioning component 60 can adapt to the tension of the chain to reduce the possibility of the conveyor chain 80 becoming loose.

[0094] During operation, the tensioning assembly 60 is continuously subjected to pressure from the conveyor chain 80, which may cause the tensioning assembly 60 to shift relative to the frame 10. The adjusting member 686 can move or be fixed relative to the guide member 682. When the tensioning assembly 60 shifts relative to the frame 10, the adjusting member 686 can be moved a certain distance relative to the guide member 682 to reset the tensioning assembly 60 relative to the frame 10, and then the adjusting member 686 can be fixed to the guide member 682.

[0095] Specifically, in this embodiment, both the fixed bracket 62 and the rotating bracket 64 can include bent sheet metal structures. The fixed bracket 62 can be fixed to the mounting bracket 20 by screw connection or welding. The upper end of the rotating bracket 64 can be rotatably connected to the fixed bracket 62 via a rotating shaft, and the lower end of the rotating bracket 64 can protrude relative to the fixed bracket 62. The tensioning member 66 can include a semi-circular plate-like structure. The tensioning member 66 can be fixed to the lower end of the rotating bracket 64 by a threaded connector. The semi-circular arc-shaped side of the tensioning member 66 forms an abutment arc surface 662, and the abutment arc surface 662 can be tilted downwards.

[0096] The guide 682 may include a threaded rod, and the adjusting member 686 may include a nut and a washer. The adjusting member 686 and the elastic abutment member 68 together clamp the frame 10. The adjusting member 686 can be turned with a wrench to move the adjusting member 686 relative to the frame 10.

[0097] The elastic abutment component 68 may include a bolt and a spring. The two ends of the bolt are respectively connected to the fixed bracket 62 and the frame 10. The spring is sleeved on the bolt. One end of the spring abuts against the rotating bracket 64, and the other end of the spring can abut against the mounting bracket 20.

[0098] In other embodiments, the fixed bracket 62 and the rotating bracket 64 may also include other structures, such as metal blocks; the tensioning member 66 may also include other structures, such as interlocking steel strips; and the elastic abutment member 68 may also include other structures, such as springs or other elastic structures.

[0099] In some embodiments, the fruit and vegetable conveying mechanism 100 further includes a drive sprocket 70, a driven sprocket, and a conveying chain 80. The drive sprocket 70 is mounted on the drive assembly 30, which drives the drive sprocket 70 to rotate. The conveying chain 80 is mounted between the drive sprocket 70 and the driven sprocket, and the abutting arc surface 662 abuts against the conveying chain 80.

[0100] With the above structure, multiple fruit cups can be installed on the conveyor chain 80. The fruit cups can be used to carry fruits and vegetables, and the drive component 30 can drive the conveyor chain 80 to move, thereby moving the fruits and vegetables.

[0101] Specifically, there can be two drive sprockets 70, and each drive sprocket 70 can correspond to one conveyor chain 80; the end of the conveyor chain 80 facing away from the drive sprocket 70 can also be fitted onto the driven sprocket on the frame 10. The driven sprocket can be rotatably connected to the frame 10.

[0102] Another embodiment of this utility model provides a fruit and vegetable sorting device, including the fruit and vegetable conveying mechanism 100 in any of the above embodiments. The fruit and vegetable sorting device may also include a feeding mechanism, a fruit and vegetable sorting mechanism, and an output mechanism. Users can load fruits and vegetables into the fruit and vegetable conveying mechanism 100 via the feeding mechanism. The fruit and vegetable conveying mechanism 100 is used to drive the fruits and vegetables through the fruit and vegetable sorting mechanism. The fruit and vegetable sorting mechanism is used to collect information about the fruits and vegetables, such as weight information or surface image information. The fruit and vegetable sorting mechanism can transport the fruits and vegetables to a corresponding output mechanism according to the information of the fruits and vegetables.
