[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-12 An agricultural product conveying device includes a fixed frame 1 and a conveyor belt 13 installed on the fixed frame 1. The two ends of the fixed frame 1 are a feeding end 11 and a discharging end 12, respectively. The conveyor belt 13 transports packaging boxes from the feeding end 11 to the discharging end 12. The device also includes a mounting frame 14, an isolation component 2, and a straightening component 3. The mounting frame 14 is fixedly connected to the fixed frame 1. The isolation component 2 includes a barrier plate 21, a drive rod 221, and a transmission rod 23. The barrier plate 21, the drive rod 221, and the transmission rod 23 are sequentially arranged on the side of the mounting frame 14 near the feeding end 11. The barrier plate 21 is slidably installed on the side of the mounting frame 14. The drive rod 221 and the transmission rod 23 are both rotatably installed on the mounting frame 14. The barrier plate 21 is connected to the drive rod 221, and one end of the transmission rod 23 is engaged with the drive rod 221.

[0037] When the drive rod 221 rotates in the forward or reverse direction, the drive rod 221 drives the barrier plate 21 to slide vertically downward or upward, which is used to block or release the packaging box, and drives the transmission rod 23 to rotate in the forward or reverse direction.

[0038] The straightening assembly 3 includes a driven rod 31 and a straightening plate 32. The driven rod 31 is rotatably mounted on the side of the mounting frame 14 near the unloading end 12. The other end of the transmission rod 23 is engaged with the driven rod 31. The upper ends of the two straightening plates 32 are respectively connected to the two ends of the driven rod 31.

[0039] When the driven rod 31 rotates in the forward or reverse direction, the transmission rod 23 drives the driven rod 31 to rotate in the reverse or forward direction, thereby driving the two straightening plates 32 to move closer together to straighten the packaging box, or driving the two straightening plates 32 to move away from each other to release the straightened packaging box.

[0040] The unloading end 12 of the fixed frame 1 is equipped with a palletizing robot. During operation, the conveyor belt 13 continuously transports several boxes from the loading end 11 of the fixed frame 1 to its unloading end 12. During the transport process, the barrier plate 21 initially slides upward to the top of the mounting frame 14, and the two straightening plates 32 move away from each other, respectively, to both sides of the conveyor belt 13. When the first box passes under the raised barrier plate 21 and enters between the two straightening plates 32, the drive rod 221 rotates forward, causing the raised barrier plate 21 to slide downward and block the conveyor belt 13, blocking subsequent boxes and pausing their movement. The driving rod 221 drives the transmission rod 23 to rotate in the forward direction. The forward rotation of the transmission rod 23, in turn, drives the driven rod 31 to rotate in the reverse direction. The rotating driven rod 31 drives the two straightening plates 32 at its two ends to move closer together, so that the two straightening plates 32 respectively abut against the two sides of the packaging box. When the packaging box is tilted or deviated to one side of the conveyor belt 13, the two straightening plates 32 will straighten the tilted packaging box and move the packaging box to the center line of the conveyor belt 13, or push the packaging box that has deviated to one side of the conveyor belt 13 to move to the center line of the conveyor belt 13, thereby ensuring that the packaging box can move straight along the center line of the conveyor belt 13. After the packaged box is positioned on the conveyor belt 13, the drive rod 221 rotates in the reverse direction, causing the descending barrier plate 21 to slide upwards and retract, allowing the next packaged box to pass underneath. Simultaneously, the rotating drive rod 221 drives the transmission rod 23 to rotate in the reverse direction, which in turn drives the driven rod 31 to rotate in the forward direction. The rotating driven rod 31 causes the two straightening plates 32 at its ends to move away from each other and to opposite sides of the conveyor belt 13, thus releasing the straightened packaged box. The straightened packaged box continues to move towards the unloading end 12 with the conveyor belt 13, while the next packaged box enters between the two straightening plates 32. Then, the drive rod... 221 drives the barrier plate 21 to slide downwards again, blocking the subsequent packaging boxes. The transmission rod 23 drives the driven rod 31 to rotate, causing the two straightening plates 32 to come together to straighten the packaging box. After the straightening is completed, the barrier plate 21 rises again to release a packaging box to be straightened. At the same time, the two straightening plates 32 move away from each other again to release the straightened packaging box. As the conveyor belt 13 continues to rotate, the straightened packaging box moves to the unloading end 12. After confirming that the traceability QR code on the packaging box is normal, it is directly picked up by the robot arm for stacking. The above steps are repeated until the conveying equipment has conveyed all the packaging boxes in the batch.

[0041] Furthermore, the top of the mounting bracket 14 is provided with slots 141, and the two slots 141 correspond to the two ends of the drive rod 221 respectively. The top of the mounting bracket 14 is also provided with a motor slot 142, which is located between the two slots 141. The fixing block 143 is fixedly connected to the mounting bracket 14, and the two fixing blocks 143 are located on the side of the two slots 141 away from the motor slot 142 respectively. The fixing block 143 is provided with a sliding groove 1431 on the side facing the barrier plate 21. The mounting bracket 14 is also provided with a gear groove 144 on the side near the barrier plate 21, which is located on the side of one of the fixing blocks 143 away from the slot 141.

[0042] Furthermore, two mounting grooves 211 are provided on the side of the barrier plate 21 facing the mounting bracket 14. The two mounting grooves 211 correspond to two slots 141 respectively. The opening of the mounting groove 211 faces the slot 141. A rack 212 is fixedly installed in the mounting groove 211. A sliding strip 213 is fixedly installed on the side of the barrier plate 21. The sliding strip 213 is slidably installed in the sliding groove 1431.

[0043] When the drive rod 221 drives the barrier plate 21 to slide up and down, the cooperation between the sliding strip 213 and the sliding groove 1431 enables the barrier plate 21 to move stably in the vertical direction, preventing the barrier plate 21 from deviating.

[0044] Furthermore, the isolation assembly 2 also includes a servo motor 22, which is fixedly installed in the motor slot 142. The output end of the servo motor 22 is rotatably connected to the drive rod 221. The two ends of the drive rod 221 are respectively rotatably installed on two fixed blocks 143. A spur gear 222 is coaxially fixedly connected to both ends of the drive rod 221. The spur gear 222 is located in the slot 141 and meshes with the rack 212. A drive bevel gear 223 is also coaxially fixedly connected to one end of the drive rod 221. The drive bevel gear 223 is located in the gear slot 144.

[0045] When the barrier plate 21 needs to be lowered, the servo motor 22 drives the drive rod 221 to rotate in the forward direction. The rotating drive rod 221 drives the rack 212 through the spur gear 222 to move the barrier plate 21 downward and drives the drive bevel gear 223 to rotate in the same direction. When the barrier plate 21 needs to be raised, the servo motor 22 drives the drive rod 221 to rotate in the reverse direction. The rotating drive rod 221 drives the rack 212 through the spur gear 222 to move the barrier plate 21 upward and drives the drive bevel gear 223 to rotate in the same direction.

[0046] Furthermore, a drive groove 145 is provided on the side of the mounting frame 14 near the unloading end 12. Both ends of the drive groove 145 are provided with fixing seats 146. The fixing seats 146 are fixedly installed on the mounting frame 14. A mounting seat 147 is fixedly installed on the mounting frame 14. The mounting seat 147 is located between the gear groove 144 and the drive groove 145.

[0047] Furthermore, the transmission rod 23 is rotatably mounted in the mounting base 147, and both ends of the transmission rod 23 are coaxially fixedly connected with transmission bevel gears 24. The two transmission bevel gears 24 are located in the gear groove 144 and the drive groove 145, respectively, wherein the transmission bevel gear 24 located in the gear groove 144 meshes with the drive bevel gear 223.

[0048] When the drive bevel gear 223 rotates in the forward or reverse direction, the drive bevel gear 223 drives the transmission rod 23 to rotate in the forward or reverse direction through the transmission bevel gear 24 meshing with it, and drives the transmission bevel gear 24 at the other end of the transmission rod 23 to rotate in the same direction.

[0049] Furthermore, the driven rod 31 is rotatably mounted on the fixed seat 146. The driven rod 31 is a bidirectional threaded rod. Both ends of the driven rod 31 are threaded, and the helical directions of the threads at both ends of the driven rod 31 are opposite. A driven bevel gear 311 is coaxially fixedly connected to one end of the driven rod 31. The driven bevel gear 311 meshes with another transmission bevel gear 24.

[0050] Specifically, when the transmission rod 23 rotates in the forward direction, the transmission rod 23 drives the driven bevel gear 311, which meshes with it, through the transmission bevel gear 24, causing the driven rod 31 to rotate in the reverse direction. When the transmission rod 23 rotates in the reverse direction, the transmission rod 23 drives the driven bevel gear 311, which meshes with it, through the transmission bevel gear 24, causing the driven rod 31 to rotate in the forward direction.

[0051] Furthermore, a connecting rod 321 is fixedly connected to the side of the straightening plate 32 near the fixed base 146. The top end of the connecting rod 321 extends out of the drive groove 145. A threaded sleeve 322 is fixedly connected to the top end of the connecting rod 321. The threaded sleeves 322 on the two straightening plates 32 are respectively threaded onto the threaded sections at both ends of the driven rod 31. A guide rod 33 is also fixedly connected to this side of the straightening plate 32. The guide rod 33 slides through the mounting bracket 14.

[0052] When the driven rod 31 rotates in the reverse or forward direction, the threaded sleeves 322 at both ends of the driven rod 31 drive the two straightening plates 32 to move closer or further apart under the engagement of the threads. During the movement of the straightening plates 32, the cooperation of the guide rod 33 and the mounting bracket 14 enables the straightening plates 32 to maintain stable linear movement and not deviate.

[0053] Furthermore, a scanning head 15 is fixedly installed on the side of the fixed frame 1, and the scanning head 15 is located at the unloading end 12 of the fixed frame 1.

[0054] When the corrected packaging box moves to the unloading end 12, the scanning head 15 will scan and identify the traceability QR code on the packaging box. If the traceability QR code on the packaging box can be identified, the robotic arm will pick up the packaging box and stack it. If it cannot be identified, it will be taken out and processed by the workers next to it.

[0055] This invention also provides a conveying method for agricultural product traceability sensing, which uses an agricultural product conveying device, and the specific steps are as follows:

[0056] First, the conveyor belt transports the packaging box from the loading end 11 to the unloading end 12. When the packaging box passes under the raised barrier plate 21 and moves between the two straightening plates 32, the drive rod 221 rotates forward, causing the barrier plate 21 to descend and block the subsequent packaging box. At the same time, the drive rod 221 drives the driven rod 31 to rotate in the opposite direction through the transmission rod 23, so that the two straightening plates 32 move closer together to straighten the packaging box. After the straightening is completed, the drive rod 221 rotates in the opposite direction, raising the barrier plate 21 to release the next packaging box. The transmission rod 23 drives the driven rod 31 to rotate forward, so that the two straightening plates 32 move away from each other, thereby releasing the straightened packaging box. Then, the straightened packaging box moves to the unloading end 12 with the conveyor belt 13. After checking the traceability QR code on the packaging box, the packaging boxes with normal traceability QR codes are stacked.

[0057] Working principle: During use, the conveyor belt 13 continuously transports several boxes from the loading end 11 of the fixed frame 1 to its unloading end 12. During the conveying process, the baffle plate 21 initially slides upward to the top of the mounting frame 14, and the two straightening plates 32 move away from each other, respectively, to both sides of the conveyor belt 13. When the first box passes under the raised baffle plate 21 and enters between the two straightening plates 32, the servo motor 22 drives the drive rod 221 to rotate forward. The rotating drive rod 221, through the spur gear 222 on it, drives the rack 212 to move the baffle plate 21 downward, blocking it across the conveyor belt 13, blocking subsequent boxes, causing the subsequent boxes to stop moving, and driving the drive bevel gear 223 to rotate in the same direction. When the drive bevel gear 223 is in the forward direction, the drive bevel gear 223 drives the transmission rod 23 to rotate in the forward direction through the transmission bevel gear 24 meshing with it, thereby driving the driven rod 31 to rotate in the reverse direction. The threaded sleeves 322 at both ends of the driven rod 31, under the engagement of the threads, drive the two straightening plates 32 at both ends to move closer to each other, so that the two straightening plates 32 respectively abut against the two sides of the packaging box. When the packaging box is tilted or deviated to one side of the conveyor belt 13, the two straightening plates 32 that move closer to each other will straighten the tilted packaging box and move the packaging box to the center line of the conveyor belt 13, or push the packaging box that has deviated to one side of the conveyor belt 13 to move to the center line of the conveyor belt 13, thereby ensuring that the packaging box can move straight along the center line of the conveyor belt 13.

[0058] After the packaging box is positioned correctly on the conveyor belt 13, the servo motor 22 drives the drive rod 221 to rotate in the opposite direction. The rotating drive rod 221, through its spur gear 222, drives the rack 212 to move the barrier plate 21 upward, retracting the barrier plate 21 so that the next packaging box can pass underneath it. This also drives the drive bevel gear 223 to rotate in the same direction. The drive bevel gear 223, through its meshing transmission bevel gear 24, drives the transmission rod 23 to rotate in the opposite direction. The reverse-rotating transmission rod 23, through the transmission bevel gear 24, drives the driven bevel gear 311 to rotate in the forward direction. The threaded sleeves 322 at both ends of the driven rod 31, under the engagement of the threads, drive the two correcting plates 32 at both ends to move away from each other and to both sides of the conveyor belt 13, thereby releasing the corrected packaging box. The corrected packaging boxes continue to move towards the unloading end 12 along the conveyor belt 13. At the same time, the next packaging box enters between the two correcting plates 32. Then, the drive rod 221 drives the blocking plate 21 to slide downward again to block the subsequent packaging boxes. The drive rod 23 drives the driven rod 31 to rotate, so that the two correcting plates 32 move closer to each other to correct the packaging box. After the correction is completed, the blocking plate 21 rises again to release a packaging box to be corrected. At the same time, the two correcting plates 32 move away from each other again to release the corrected packaging box. As the conveyor belt 13 continues to rotate, the corrected packaging box moves to the unloading end 12. After confirming that the traceability QR code on the packaging box is normal, it is directly picked up by the robotic arm for stacking. The above steps are repeated until the conveying equipment has transported all the packaging boxes in the batch.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

10. A conveying method for agricultural product traceability sensing, characterized in that: The agricultural product conveying equipment according to any one of claims 1-9 is used, and the specific steps are as follows: First, the conveyor belt transports the packaging boxes from the loading end to the unloading end. When the packaging box passes under the raised barrier plate and moves between the two straightening plates, the drive rod rotates forward, causing the barrier plate to descend and block subsequent packaging boxes. At the same time, the drive rod drives the driven rod to rotate in the opposite direction through the transmission rod, causing the two straightening plates to move closer together and straighten the packaging box. After straightening is completed, the drive rod rotates in the opposite direction, raising the barrier plate to release the next packaging box. The drive rod then drives the driven rod to rotate forward, causing the two straightening plates to move away from each other, thus releasing the straightened packaging box. Subsequently, the straightened packaging box moves with the conveyor belt to the unloading end. After checking the traceability QR code on the packaging box, the packaging boxes with normal traceability QR codes are stacked.
