A conveyor belt 6 is provided in the installation groove 5.

[0026] Embodiment 2;

[0027] As Figures 1-4As shown in the figure, it includes a base 1. A number of evenly distributed rollers 2 are provided at the bottom end of the base 1. An anti-slip component matching the rollers 2 is provided at the bottom end of the base 1. An inclined mounting frame 3 is provided at the top end of the base 1. One side of the mounting frame 3 is connected to the base 1 through a first rotating shaft 4. The bottom end of the mounting frame 3 is connected to the base 1 through an angle adjustment component. An installation groove 5 is opened at the top end of the mounting frame 3. A conveyor belt 6 is provided in the installation groove 5. The anti-slip component includes a dual-axis motor 7 provided at the bottom end of the base 1. First lead screws 8 are provided at both driving ends on both sides of the dual-axis motor 7. The two groups of first lead screws 8 are connected to the base 1 through a fixed seat 9. Movable sleeves 10 are sleeved on the outer walls of the two groups of first lead screws 8. Connecting rods 11 are provided on the sides of the two groups of movable sleeves 10 away from each other. A U-shaped frame 12 is provided at the bottom end of the connecting rod 11. An arc-shaped clamping plate 13 matching the roller 2 is provided on one side of the U-shaped frame 12. The first lead screw 8 is connected to the fixed seat 9 through a first bearing. A thread groove matching the first lead screw 8 is opened on the inner wall of the movable sleeve 10. A guiding block 14 is provided on the outer wall of the movable sleeve 10. A guiding groove matching the guiding block 14 is opened at the bottom end of the base 1. An anti-slip pad is provided on the concave surface of the arc-shaped clamping plate 13. Before unloading the goods, first move the base 1 to the designated position through the rollers 2. After completion, start the dual-axis motor 7 to drive the two groups of first lead screws 8 to rotate. The first lead screw 8 is in threaded connection with the movable sleeve 10, and the movable sleeve 10 cannot rotate due to the guiding and limiting of the guiding block 14 and the guiding groove. Therefore, when the first lead screw 8 rotates, it will drive the movable sleeve 10 to move.

By setting the anti-slip component, the roller can be limited, preventing the base from sliding during unloading and causing the goods to fall, further improving its safety.

[0028] Embodiment 3;

[0029] As Figures 1-4As shown in the figure, it includes a base 1. A number of uniformly distributed rollers 2 are provided at the bottom end of the base 1. An anti-slip component matching the rollers 2 is provided at the bottom end of the base 1. An inclined mounting frame 3 is provided at the top end of the base 1. One side of the mounting frame 3 is connected to the base 1 through a first rotating shaft 4. The bottom end of the mounting frame 3 is connected to the base 1 through an angle adjustment component. An installation groove 5 is provided at the top end of the mounting frame 3. A conveyor belt 6 is provided in the installation groove 5. The angle adjustment component includes an upright frame 15 provided at the top end of the base 1. A horizontally arranged second lead screw 16 is provided in the upright frame 15. A movable block 17 is sleeved on the outer wall of the second lead screw 16. The top end of the movable block 17 is connected to the mounting frame 3 through two groups of symmetrically arranged movable support rods 18. The second lead screw 16 is connected to the upright frame 15 through a second bearing. One side of the second lead screw 16 extends outside the upright frame 15 and is connected to the driving end of a servo motor 19. A threaded hole matching the second lead screw 16 is provided on the movable block 17. Guide support rods 20 which are symmetrically arranged and penetrate through the movable block 17 are provided in the upright frame 15. A sliding hole matching the guide support rods 20 is provided on the movable block 17. The movable support rods 18 are respectively connected to the mounting frame 3 and the movable block 17 through second rotating shafts 21. When unloading goods, according to the actual height difference at the unloading location, start the servo motor 19 to drive the second lead screw 16 to rotate. The second lead screw 16 is threadedly connected to the movable block 17. The movable block 17 is guided and limited by the guide support rods 20. When the second lead screw 16 rotates, it drives the movable block 17 to move. The movable block 17 supports and rotates the mounting frame 3 through the movable support rods 18. The mounting frame 3 drives the conveyor belt 6 to adjust to a suitable angle. Then place the goods on the conveyor belt 6 for conveying. By setting the angle adjustment component, the inclination angle of the conveyor belt can be adjusted according to the height difference at the unloading location, improving its application range and making it more flexible and convenient to use.

[0030] In practical applications, before unloading the goods, first move the base 1 to the designated position through the rollers 2. After that, start the double-shaft motor 7 to drive the two groups of lead screws 8 to rotate. The lead screws 8 are threadedly connected to the movable sleeves 10, and the movable sleeves 10 are guided and limited by the guide blocks 14 and the guide grooves and cannot rotate. Therefore, when the lead screws 8 rotate, they will drive the movable sleeves 10 to move. The movable sleeves 10 drive the arc-shaped clamping plates 13 to move and press the rollers 2 through the U-shaped frames 12, preventing the rollers 2 from rotating. By setting the anti-slip component, the rollers can be limited, preventing the base from sliding during the unloading process and causing the goods to fall, further improving its safety. When unloading the goods, according to the actual height difference at the unloading location, start the servo motor 19 to drive the lead screw 16 to rotate. The lead screw 16 is threadedly connected to the movable block 17, and the movable block 17 is guided and limited by the guide support rod 20. When the lead screw 16 rotates, it drives the movable block 17 to move. The movable block 17 supports and rotates the mounting frame 3 through the movable support rod 18, and the mounting frame 3 drives the conveyor belt 6 to be adjusted to an appropriate angle. Then, place the goods on the conveyor belt 6 for transportation. By setting the angle adjustment component, the inclination angle of the conveyor belt can be adjusted according to the height difference at the unloading location, improving its applicable range and making it more flexible and convenient to use.

[0031] In summary, by means of the above technical solutions of the present invention, the rollers can be limited by setting the anti-slip component, preventing the base from sliding during the unloading process and causing the goods to fall, further improving its safety. By setting the angle adjustment component, the inclination angle of the conveyor belt can be adjusted according to the height difference at the unloading location, improving its applicable range and making it more flexible and convenient to use.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
