[0002] Scraper conveyor is an important conveying equipment widely used in mining, metallurgy, chemical industry and other industries. The scraper chain device is the core component of the scraper conveyor. Through the synergistic effect of the scraper and the chain, it can continuously transport materials from one place to another, thereby improving production efficiency. Its conveying speed and conveying volume can be adjusted according to actual production needs to meet the requirements of production of different scales. Moreover, in harsh working environments such as mines, the scraper chain device can withstand the influence of adverse factors such as high temperature, high humidity, and high dust. Its sturdy structure and wear-resistant materials can ensure long-term stable operation under harsh conditions, reducing equipment failures and maintenance times. In summary, the scraper chain device of the scraper conveyor plays a core role in modern production, improves overall efficiency, and provides strong technical support for the production management and operation of the enterprise.

[0003] Existing scraper chain devices often use a welding fixation method for the scraper and chain. Although this simplifies the structural design to a certain extent, fatigue cracks will occur at the welding points due to long-term operation, which will cause the scraper and chain to separate, affecting the conveying efficiency and safety. Moreover, when the scraper or chain is damaged, the welding fixation design will make the replacement operation complicated, and manual cutting of the welding points is required, which increases maintenance costs and time. Moreover, due to thermal expansion and contraction during welding, the welding points may be deformed during use, thereby affecting the operation effect of the scraper and the stability of the chain.

[0004] Therefore, it is urgent to provide a scraper chain device for a scraper conveyor to solve the above problems. Utility Model Content

[0015] Through the above technical solutions, the overall operating costs are reduced and the economy and reliability of the equipment are improved.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model places the scraper together with the connecting component into the groove of the chain, and then rotates the handle to rotate the threaded rod, so that the threaded rod pushes the wedge bar to move, and then the sleeve moves in the direction of the spring, squeezing the spring, and with the cooperation of the through groove, the limit plate is caused to rotate to engage the inner wall of the chain. Since the threaded rod has a self-locking function, the scraper and the connecting component can be quickly connected and fixed, and at the same time, it is convenient to disassemble, making it faster to replace the scraper or chain, reducing downtime and improving maintenance efficiency. In addition, the scraper can be flexibly adjusted or replaced according to different material properties or working conditions to improve adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
