[0028] Further, the front surface of the mounting frame 1 located at the front side is provided with a circular groove 14, a rectangular groove 15 is formed in the inner wall of the circular groove 14, the rear end of the first rotating rod 7 extends into the interior of the rectangular groove 15, and a rectangular sound-absorbing plate 18 is fixedly installed on the inner wall of the rectangular groove 15.

[0029] Further, the noise generated by the sorting belt machine is reduced through the U-shaped sound-absorbing plate 6 and the rectangular sound-absorbing plate 18, and the first transmission belt 13 and the second transmission belt 17 are arranged in the interior of the mounting frame 1 and the power box 5, so that the remaining noise is further reduced, and the noise is prevented from directly entering the working environment, thereby reducing the noise degree of the sorting belt machine, improving the working environment of workers, and improving the working efficiency of workers.

[0030] Further, two connecting rods 16 are rotatably installed on the rear inner wall of the rectangular groove 15, the first rotating rod 7 is fixedly connected with the connecting rod 16 at the right end, the two connecting rods 16 are in transmission connection through the second transmission belt 17, the rear ends of the two connecting rods 16 respectively extend to the front ends of the driven roller 2 and the driving roller 3, and the two connecting rods 16 are respectively fixedly connected with the corresponding driven roller 2 and driving roller 3.

[0033] Working principle: When using this belt conveyor, start the driving motor 12 to rotate the output end of the driving motor 12. The output end of the driving motor 12 rotates, driving the first rotating rod 7 connected to the driving motor 12 through the first transmission belt 13 to rotate, and the connecting rod 16 fixedly connected to the first rotating rod 7 starts to rotate. The active roller 3 fixedly connected to the rear end of the connecting rod 16 at the right end rotates, thereby rotating the left connecting rod 16 connected to the right end of the connecting rod 16 through the second transmission belt 17, thereby driving the driven roller 2 and the active roller 3 fixedly connected to the rear ends of the two connecting rods 16 to rotate, thereby rotating the sorting belt 4 on the outer surface of the driven roller 2 and the active roller 3, thereby moving the objects on the sorting belt 4. During the movement, the worker sorts the objects on the sorting belt 4. When it is necessary to make the sorting belt conveyor run at high speed, adjust the output power of the driving motor 12 to make the first rotating rod 7 run at high speed, thereby making the connecting rod 16 start to run at high speed, thereby making the driven roller 2 and the active roller 3 rotate quickly, thereby making the sorting belt 4 run at high speed. When the driving motor 12 in the sorting belt conveyor drives the first rotating rod 7 to rotate through the first transmission belt 13, the noise generated is absorbed and reduced by the U-shaped sound absorbing panel 6, and the remaining noise is reduced by the power box 5, thereby reducing the noise of the sorting belt conveyor. When the two connecting rods 16 rotate through the second transmission belt 17, the contrast generated by the friction between the two connecting rods 16 and the second transmission belt 17 is absorbed and reduced by the rectangular sound absorbing panel 18, and the remaining noise is reduced by the mounting frame 1, thereby further reducing the noise generated by the sorting belt conveyor. When the driving motor 12 runs at high speed, it will generate a certain amount of vibration. When the driving motor 12 vibrates, it drives the mounting plate 11 fixed to the lower end of the driving motor 12 to vibrate at the same time, thereby driving the four dampers 9 and four springs 10 fixed to the lower surface of the mounting plate 11 to compress downward, reducing the vibration amplitude of the driving motor 12, thereby reducing the vibration of the driving motor 12 during operation, thereby reducing the vibration of the driving motor 12, and further reducing the noise generated by the driving motor 12 during operation.
