1. At present, our oilers are made of plastic and filled with lubricant. Before drilling, we must turn on the oiler switch, the operation is relatively complicated. The most unfavorable thing is that the oiler is likely to be damaged during frequent worker movements. Therefore, manufacturers should change the oiler to metal products. 7655 Type wind drills can be drilled by simply injecting butter into the duct joint.
2. Weight is 2.5 kg more than 7655 type air leg rock drill, which increases the labor intensity of the operators. Manufacturers should have made some improvements in reducing the weight.
3. Because the power of YT29 air leg rock drill is larger than 7655 wind drill, the working surface of the mine is far away and the working time is short. Manufacturers can change the YT29 air leg rock drill into FT170 air leg, it can increase the inner diameter of the cylinder and increase the speed of the drill.
