Step 3: the second motor 39 drives one group of second belt pulleys 37 to rotate, the second belt pulleys 37 drive the other group of second belt pulleys 37 to rotate through the second belt 38, the pipe sleeve 32 is driven to rotate when the second belt pulleys 37 rotate, the rotating column 31 is driven to rotate under the restriction of the first limiting block 35 when the pipe sleeve 32 rotates, and the second conveying belt 42 is driven to rotate by friction when the two groups of pipe sleeves 32 rotate, so that the transportation of objects is realized; when the second conveyer belt 42 rotates, the first conveyer belt 41 is driven to rotate under the limitation of the second limiting block 43, and when the first conveyer belt 41 rotates, the limiting ring 51 is driven to rotate, and the limiting ring 51 is limited by the sliding rail 52, so that the first conveyer belt 41 can be prevented from deviating when rotating.

In addition, the belt conveyor of this embodiment can also extend the length of the conveyor belt, specifically, the connecting block 64 on the table 62 of another belt conveyor is aligned with the through hole at the bottom of the inner cavity of the table 62 of this belt conveyor, and then the pin 65 is inserted into the connecting block 64 and the through hole, so that the two belt conveyors are butted together to extend the length of the conveyor belt. In actual use, the movement of the table 62 is assisted by the universal wheel 63.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
