The coal is carbonized in the carbonization chamber to form metallurgical coke. At the middle and late coking stage, graphite will be produced on the side wall and top of the carbonization chamber. If the accumulated graphite is not cleaned up in time and the graphite thickness is accumulated to a certain extent, the coal loading port and riser of the carbonization chamber will be blocked, and the coal material can not be loaded into the carbonization chamber, affecting the normal production, The blockage of the riser and the deposition of graphite on the upper part of the carbonization chamber will affect the normal export of raw gas and the stability of production. The deposition of graphite will also affect the working stability of the coke pusher. At present, the pushing rod with scraper is widely used to clean the graphite in the industry. The purpose is to reduce the occupation of production time and reduce the labor intensity. In the prior art, for example, the utility model patent with application number of 201620607726.6 includes the scraper base and the scraper head. The scraper base is connected with the rod body of the pushing rod for the pushing coke machine, The scraper head is installed in the scraper base. Although the structure of the utility model is simple, the rigidity of the push rod is insufficient, the front end of the push rod has no support, and the push rod needs manual operation, which is time-consuming and laborious, and can not meet the needs of users.
