In coal mining faces, the shearer, scraper conveyor, and support equipment together form a set of coal mining machinery. The compatibility between their operational capabilities and structural dimensions directly affects the smooth implementation of the coal mining process as well as the full utilization of the equipment’s capabilities. Taking the SGZ764/630 type scraper conveyor as an example, due to the large size of the oil tank at the end of its sprocket assembly, the oil tank of the rear scraper conveyor often suffers from deformation as a result of being compressed by gangue and the columns of the end frame, which leads to sprocket damage and oil leakage, thereby affecting normal production. Through analysis and research, the tank was modified, reducing its volume to suit the production environment. To address the existing problems, through analysis and research, the focus is on preventing compression between the hydraulic support and the debris falling from the mountain; it is planned to reprocess the oil tank in order to reduce the likelihood of it being compressed. The composition and technical parameters of this device are as follows: a circular steel plate with a material thickness of 60 mm and a diameter of 450 mm. The modified fuel tank is made of steel plate using a lathe; it is easy to install. Once installed, the tank is secured with six screws. Compared to the original sprocket assembly’s fuel tank, its thickness is reduced by at least 210 mm. Features of the modified version: 1. Small space occupation, reliable, simple, easy to use, and low cost ； 2. It reduces the occurrence of oil leakage incidents and saves grease ； 3. It facilitates the scaffold workers in moving the end frames, reduces the damage rate of sprocket components, and improves production efficiency. During its use in a mine working face, this device significantly reduced the damage rate of sprocket components, ensured the normal operation of the working face, and improved economic efficiency; it therefore holds great potential for widespread application.
