Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] Reference Figures 1-2 As shown, this utility model provides a technical solution: a polycrystalline silicon transport vehicle with automatic loading and unloading connection function, including: a base plate 1, a baffle 8 fixedly connected to the top of the base plate 1, a box 2 provided at the top of the base plate 1, a first groove 12 opened on one side of the base plate 1, a loading and unloading component 3 provided inside the first groove 12, a QR code display screen 82 provided on one side of the baffle 8, a controller provided inside the baffle 8, and the QR code display screen 82 electrically connected to the controller.

[0026] Reference Figures 1-5As shown in this embodiment: a polycrystalline silicon transport vehicle with automatic loading and unloading connection function, the loading and unloading assembly 3 includes a first motor 31 installed inside the first groove 12, a threaded rod 32 fixedly connected to the output end of the first motor 31, a first L-shaped plate 33 threadedly connected to the outer surface of the threaded rod 32, a top plate 34 fixedly connected to one side of the first L-shaped plate 33, a C-shaped mounting plate 35 fixedly connected to one side of the top plate 34, a second motor 36 installed on one side of the C-shaped mounting plate 35, a rotating rod 37 fixedly connected to the output end of the second motor 36, a connecting rope 38 wound around the outer surface of the rotating rod 37, and a connecting hook 39 fixedly connected to one end of the connecting rope 38. A mounting block 21 is fixedly connected to the top of the housing 2, and a connecting ring 211 is fixedly connected to the top of the mounting block 21. One end of the threaded rod 32 is rotatably connected to the inner wall of the first groove 12, and the rotating rod 37 rotates through the C-shaped mounting plate 35. The QR code display screen 82 is electrically connected to a controller installed inside the baffle 8. The controller receives material information data packets from the factory material management system or warehouse management system via a wireless communication module. This data packet contains information such as the material code, grade, main physicochemical properties, production batch number, and weight of a specific batch of polycrystalline silicon rods loaded in the corresponding box 2. The controller generates a corresponding dynamic QR code image in real time based on the received data packet and drives the QR code display screen 82 to display it. Production personnel scan the real-time dynamic QR code on the QR code display screen 82 with a handheld PDA to obtain material information, such as the material grade and physicochemical properties of the polycrystalline silicon rods. Box 2 is used to place silicon rods. Box 2 is integrally cast from PU material, which is a non-metallic material, to avoid contamination caused by contact between silicon rods and metal, and to meet the high purity requirements of semiconductor materials. Connecting hook 39 is connected to connecting ring 211. The second motor 36 drives rotating rod 37 to rotate. Rotating rod 37 rotates to retract and release connecting rope 38 to adjust the connecting rope 38 to a suitable length. The first motor 31 drives threaded rod 32 to rotate. The rotation of threaded rod 32 drives the first L-shaped plate 33 to move along the axis of threaded rod 32, thereby driving the top plate 34 to move. Under the action of connecting rope 38, it is easy to pull box 2 to realize automatic loading or unloading operation.

[0027] A second groove 13 is formed on the side of the base plate 1 away from the first groove 12. A slide rod 7 is fixedly connected inside the second groove 13, and a second L-shaped plate 71 is slidably connected to the outer surface of the slide rod 7. The second L-shaped plate 71 is fixedly connected to the top plate 34. When the threaded rod 32 rotates and drives the top plate 34 to move, the second L-shaped plate 71 slides along the outer surface of the slide rod 7, which plays a guiding role and makes the movement of the top plate 34 more stable.

[0028] A U-shaped mounting plate 22 is fixedly connected to the bottom of the housing 2. A first rotating shaft 6 is rotatably connected inside the U-shaped mounting plate 22. A roller 61 is fixedly connected to the outer surface of the first rotating shaft 6. A first sliding groove 15 is opened at the top of the bottom plate 1, and the roller 61 is slidably connected to the first sliding groove 15. When the housing 2 is pulled by the loading and unloading assembly 3, the roller 61 slides along the first sliding groove 15, reducing friction and facilitating the movement of the housing 2, while also serving a guiding function.

[0029] A connecting plate 16 is fixedly connected to one side of the base plate 1. A second rotating shaft 5 is rotatably connected to the inner side of the connecting plate 16. A guide plate 51 is fixedly connected to the outer surface of the second rotating shaft 5. A second sliding groove 511 is provided at the top of the guide plate 51. A roller 61 is slidably connected to the second sliding groove 511. The first sliding groove 15 is correspondingly set with the second sliding groove 511. The guide plate 51 is manually driven to rotate downward, so that the guide plate 51 gradually unfolds and contacts the ground, forming a slope. An anti-slip rubber pad (not shown in the figure) is provided at the bottom of the end of the guide plate 51 that contacts the ground. At this time, the second sliding groove 511 forms a continuous sliding path at the extension of the first sliding groove 15, which facilitates the smooth transition of the box 2 from the first sliding groove 15 to the second sliding groove 511, and then slides down the second sliding groove 511 to the ground to complete the unloading.

[0030] A limit rod 512 is fixedly connected to one side of the guide plate 51, and a first locking bolt 5121 is threadedly connected between the limit rod 512 and the baffle 8. When the guide plate 51 is retracted from the ground and rotated upward to a vertical position, the guide plate 51 no longer functions as a sliding track, but enters a retracted and locked state, serving as a limit. At this time, the guide plate 51 is fixed to the baffle 8 by the first locking bolt 5121 to prevent the guide plate 51 from loosening.

[0031] The outer surface of the baffle 8 has a first threaded hole 81, and the outer surface of the housing 2 has a second threaded hole 23. A second locking bolt 811 is threadedly connected between the first threaded hole 81 and the second threaded hole 23. Multiple sets of first threaded holes 81 are provided. After the housing 2 is pulled to the designated position, the roller 61 is inserted into the first sliding groove 15, and the second locking bolt 811 passes through the first threaded hole 81 and connects to the second threaded hole 23, which facilitates fixing the housing 2 and prevents the housing 2 from shaking. Multiple sets of first threaded holes 81 facilitate fixing the housing 2 in different positions.

[0032] A support leg 14 is fixedly connected to the bottom end of the base plate 1, and a caster wheel 141 is installed at the bottom end of the support leg 14. A traction plate 11 is fixedly connected to one side of the base plate 1, and a traction groove 111 is provided at the top of the traction plate 111. There are three sets of traction grooves 111. The caster wheel 141 provides omnidirectional free movement capability and has a self-locking function. When it is necessary to fix it, the self-locking function is activated to prevent accidental slippage. External traction equipment can be quickly connected through the traction grooves 111. The three sets of traction grooves 111 facilitate the traction of external traction equipment from different directions.

[0033] A protective frame 4 is fixedly connected to one side of the C-shaped mounting plate 35, and a protective cover 41 is movably connected to one side of the protective frame 4. The second motor 36 is located inside the protective frame 4. The protective frame 4 protects the second motor 36.

[0034] Working principle: The housing 2 is used to place silicon rods. The guide plate 51 is manually driven to rotate downwards, so that the guide plate 51 gradually unfolds and contacts the ground, forming a slope. At this time, the second slide 511 extends from the first slide 15, forming a continuous sliding path. The connecting hook 39 is manually connected to the connecting ring 211. The second motor 36 drives the rotating rod 37 to rotate. The rotating rod 37 rotates to retract the connecting rope 38 to adjust the connecting rope 38 to a suitable length. The first motor 31 drives the threaded rod 32 to rotate. The rotation of the threaded rod 32 drives the first L-shaped plate 33 to move along the axis of the threaded rod 32, thereby driving the top plate 34 to move. Under the action of the connecting rope 38, it is easy to pull the housing 2, so that the housing 2 is pulled through the second slide 511 to the first slide 15, realizing automatic loading. After loading is completed, it is then... The second locking bolt 811 passes through the first threaded hole 81 and connects to the second threaded hole 23, which facilitates the fixing of the box 2 and prevents the box 2 from shaking. Then, the guide plate 51 is retracted from the ground and rotated upward to a vertical state. At this time, the guide plate 51 is no longer used as a sliding track, but enters a retracted and locked state, which serves as a limit. At this time, the guide plate 51 is fixed to the baffle 8 by the first locking bolt 5121 to prevent the guide plate 51 from loosening. The external traction equipment can quickly connect with the bottom plate 1 through the traction groove 111 to carry out traction operation. When unloading is required, the second locking bolt 811 and the first locking bolt 5121 are loosened. Similarly, the box 2 is pulled by the connecting rope 38 so that the box 2 smoothly transitions from the first slide groove 15 to the second slide groove 511, and then slides down the second slide groove 511 to the ground to complete the unloading.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
