[0020] The adjustment mechanism includes an installation cavity 6, a first servo motor 7, a driving gear 8, a driven gear 9, a threaded sleeve 10, a threaded rod 11 and a limiting structure. The installation cavity 6 is installed on the outside of the side plate 2. The first servo motor 7 is installed at one end of the installation cavity 6. The driving gear 8 is installed on one side of the interior of the installation cavity 6. The output end of the first servo motor 7 is connected to one end of the driving gear 8. The driven gear 9 is engaged with one side of the driving gear 8. The threaded sleeve 10 is installed inside the driven gear 9. The threaded sleeve 10 is provided with a threaded rod 11 running through the interior of the threaded sleeve 10. One end of the threaded rod 11 extends to the inner side of the side plate 2. One end of the threaded rod 11 is connected to one side of the first positioning plate 4. When in use, start the first servo motor 7 to drive the driving gear 8 to rotate. Since the driving gear 8 and the driven gear 9 are engaged with each other, the driven gear 9 is used to drive the threaded sleeve 10 to rotate under the limit of the limit rail 12 and the limit block 13. Since the threaded sleeve 10 is threadedly connected to the threaded rod 11, the threaded sleeve 10 is used to drive the threaded rod 11 to move, and then under the limit of the positioning hole 14 and the positioning rod 15, the threaded rod 11 is used to drive the first positioning plate 4 to move, and the first positioning plate 4 is used to perform preliminary fixing treatment on the material box, so that the material box is more stable during transportation and not easy to fall, so the transportation effect of agricultural products is better, thereby greatly improving the practicality of the transfer rack when in use.

[0021] The limiting structure includes a limiting rail 12, a limiting block 13, a positioning hole 14 and a positioning rod 15. The limiting rail 12 is installed on one side of the installation cavity 6. The limiting block 13 is arranged inside the limiting rail 12. One end of the limiting block 13 is connected to the outer side of the threaded sleeve 10. The positioning hole 14 is opened at both ends of the side plate 2. A positioning rod 15 is arranged inside the positioning hole 14. One end of the positioning rod 15 is connected to one side of the first positioning plate 4. The inner diameter of the positioning hole 14 is larger than the outer diameter of the positioning rod 15. The positioning hole 14 is provided with a plurality of holes. 4 and the positioning rod 15 form a sliding structure, and two limit blocks 13 are provided inside the limit rail 12. The two limit blocks 13 are symmetrically distributed about the central axis of the limit rail 12. When in use, the limit rail 12 and the limit blocks 13 cooperate with each other to limit the threaded sleeve 10 during rotation, so that the threaded sleeve 10 is more stable during rotation. The positioning hole 14 and the positioning rod 15 cooperate with each other to position the first positioning plate 4 during movement, so that the first positioning plate 4 is more stable during movement.

[0022] The moving mechanism includes a second servo motor 16, a screw 17, a screw sleeve 18 and a guide structure. The second servo motor 16 is installed inside the side panel 2. The output end of the second servo motor 16 is installed with a screw 17. The outer side wall of the screw 17 is provided with a screw sleeve 18. One end of the screw sleeve 18 is connected to one side of the second positioning plate 5. When in use, the second servo motor 16 is started to drive the screw 17 to rotate. Therefore, under the limitation of the guide groove 19 and the guide block 20, the screw sleeve 18 is driven by the screw 17 to move, and then the second positioning plate 5 is driven to move. Therefore, the second positioning plate 5 is used to perform a secondary fixation process on the material box, so that the material box is more stable during transportation, thereby improving the stability of the transfer rack during use.

[0023] The guide structure includes a guide groove 19 and a guide block 20. The guide groove 19 is opened inside the side plate 2. The guide block 20 is provided inside the guide groove 19. One end of the guide block 20 is connected to one side of the screw sleeve 18. When in use, the screw sleeve 18 can be guided when moving by utilizing the mutual cooperation between the guide groove 19 and the guide block 20, so that the screw sleeve 18 is more stable when moving.

[0024] Working principle: The staff first places the material box containing agricultural products on the bottom plate 1 and the mounting plate 3, and then starts the first servo motor 7 to drive the driving gear 8 to rotate. Since the driving gear 8 and the driven gear 9 are engaged with each other, the driven gear 9 drives the threaded sleeve 10 to rotate under the limit of the limit rail 12 and the limit block 13. Since the threaded sleeve 10 is threadedly connected to the threaded rod 11, the threaded sleeve 10 drives the threaded rod 11 to move. Then, under the limit of the positioning hole 14 and the positioning rod 15, the threaded rod 11 drives the first positioning plate 4 to move. The first positioning plate 4 performs a preliminary fixing process on the material box, and then the second servo motor 16 is started to drive the screw 17 to rotate. Therefore, under the limit of the guide groove 19 and the guide block 20, the screw 17 is used to drive the screw sleeve 18 to move, and then drive the second positioning plate 5 to move. Therefore, the second positioning plate 5 is used to perform a secondary fixing process on the material box, so that the material box is not easy to fall during transportation, thereby ensuring the safety of agricultural products during transportation. When the material box needs to be removed, the first servo motor 7 and the second servo motor 16 are started to reverse them, and the first positioning plate 4 and the second positioning plate 5 are respectively driven to return to their original positions.
