Description

Technical Field

[0001] This utility model relates to the field of highway engineering technology, and more specifically, to a front obstacle clearing device for a tracked chassis hammer crusher. Background Technology

[0002] In the existing operation of tracked chassis hammer crushers, large stones need to be placed into the crushing box for crushing before being laid on the road surface.

[0003] Currently, some crushers use relatively simple obstacle-clearing devices, mostly fixed scrapers. These fixed scrapers can only clear obstacles in one direction and cannot be flexibly adjusted according to different road conditions. When encountering uneven road surfaces, the fixed scraper either fails to effectively remove debris from depressions or causes excessive friction with the ground at protrusions, leading to scraper damage, affecting the obstacle-clearing effect and the service life of the equipment.

[0004] Some obstacle removal devices, while possessing certain adjustment functions, have complex adjustment methods, require manual operation, and lack precision. In actual operation, the crusher's travel speed and working environment change rapidly, and manual adjustments cannot adapt to these changes in a timely manner, resulting in ineffective and untimely obstacle removal work, which in turn affects the overall working efficiency of the crusher.

[0005] In addition, existing obstacle removal devices have some shortcomings in their structural design. Their support and positioning structures are not stable enough, making them prone to shaking and displacement during the obstacle removal process. This results in inaccurate movement trajectories of the obstacle removal scraper, preventing precise removal of obstacles. Furthermore, the scraper structure of some obstacle removal devices is not conducive to the discharge of debris, easily causing material accumulation and further reducing the obstacle removal effect.

[0006] How to effectively solve the above problems is an important issue that needs to be addressed for the further development of crushers. Utility Model Content
