[0002] The main role of the coke scraping machine is to scrape the semi-coke from the furnace bottom or grate of the vertical carbonization furnace and transport it to the coke collecting bin or other processing equipment. For example, in the semi-coke production process, the semi-coke is scraped out by the coke scraping machine after cooling and enters the coke screening section for further processing. In addition, the coke scraping machine is also used to process the materials that fall off during the cleaning of the furnace door. The rear transmission shaft in the coke scraping machine is an important component of the transmission system of the coke scraping machine, and its main function is to transmit power from the driving device to the execution mechanism such as the scraping arm, thereby driving the movement of the coke scraping machine.

[0003] In the prior art, since the rear transmission shaft operates in a closed coke discharge tank, the coaxiality cannot be determined when adjusting the square bushing seat at both ends, causing the shaft to be stuck and unable to rotate, resulting in the original rotary motion becoming a friction motion, aggravating the wear of the chain, the scraping lever, and the rear wheel body, increasing the power load of the scraper, causing the chain to break, the scraping lever to bend, and the speed reducer to be damaged, which may cause equipment safety accidents. Moreover, since the rear transmission shaft operates in a closed space and the working temperature is about 200 degrees, the lubrication of the copper-based sliding bearing in the square bushing seat cannot be guaranteed, and in addition to a large amount of ammonia gas and micro-focal dust, the existing bushing seal cannot effectively protect the clean lubrication of the copper sliding bearing, causing the sliding bearing and the shaft body to be stuck.
