The lower end of the seal 17 is connected to the next cylinder body 9, and a trigger mechanism is provided at the lower end of the seal 17. After the trigger mechanism is triggered, the seal 17 moves downward and no longer separates the lower two cylinder bodies 10; specifically, in the initial state, the upper end of the right scraper 151 is connected to the conveyor belt 3, and the right second scraper 152 is not connected to the conveyor belt 3 at this time. During continuous use, the right first scraper 151 is continuously worn, so that the movable block 20 in the next cylinder body 9 moves to the right, until the right first scraper 151 is worn to a certain extent, and the movable block 20 moves to the right and touches the trigger mechanism to stimulate it, so that the lower two cylinder bodies 10 are connected, and the right second scraper 152 is connected upward to the conveyor belt 3 under the action of the adjusting spring 21; when the right first scraper 151 is worn to a certain extent, it is automatically triggered to replace it with a new right second scraper 152, thereby extending the service life of the scraper 15 and avoiding frequent replacement of the scraper 15.
