When detecting and replacing oil downhole, the intelligent coal mining machine is first put into service mode (swing arm level), as shown in fig. 1. The rocker arm fueling was then observed through a dipstick or oil window.
As shown in FIG. 2, when the rocker arm 1 is higher than the horizontal state, the oil filling amount of the oil 3 is observed through the stock rod scale 21 or the oil window of the stock rod 2, the oil filling amount of the rocker arm is reduced, and the splashing lubrication of the gear and the bearing is poor, so that the temperature of the rocker arm is increased. As shown in figure 3, when the rocker arm 1 is lower than the horizontal state, the oil filling amount of the oil 3 is observed through the stock rod scale 21 or the oil window of the stock rod 2, the oil filling amount of the rocker arm is increased, the friction between a gear and the oil is increased, and the temperature of the rocker arm rises.
