Urea bucket elevator is mainly composed of traction components (such as chains, belts, etc.), hoppers, drive devices, tensioning devices, casings, etc. Its working principle is to drive the traction components to rotate through the drive device, so that the hopper fixed on the traction components continuously moves vertically in the casing, thereby realizing the vertical transportation of urea.

[0003] However, in the prior art, the staff adds the material into the storage box and then starts the driving device, which drives the elevator to operate. The material entering the storage box enters the interior of the lifting frame through the feed pipe and falls into the hopper, and is transported upward by the rotation of the hopper.

The threads of the threaded rod 52 are opposite, and the rotation of the threaded rod 52 causes the slider 522 to move. The movement of the slider 522 pushes the lifting rod 524 to move through the first movable head 523, and the lifting rod 524 pushes the second movable head 525 to move away from or closer to each other. The second movable head 525 moves through the support block 526, so that the support block 526 pushes the discharge bin 12 to slide up and down, adjusting the distance between the discharge bin 12 and the hopper 45, so that the hopper 45 can shovel the material in the discharge bin 12 into the hopper 45, thereby facilitating the material transportation in the discharge bin 12.
