In addition, the connection position of the buffer cylinder 1101 and the first supporting component 9 and the connection position of the buffer cylinder 1101 and the second supporting component 10 can be adjusted, so that the position of the buffer cylinder 1101 can be adjusted conveniently to achieve different buffering effects, different working condition requirements are met, and the applicability of the scraper is improved.
The principle and the implementation mode of the invention are explained by applying a specific example, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the foregoing, the description is not to be taken in a limiting sense.
