1.After the coal loading car is aligned, turn on the automatic feeder to unload the coal for about 20 seconds. The feeder stops automatically and is ready for tamping.
2. Open the bumper before tamping. Because the bumper is under the tamping hammer, it is to prevent the tamping hammer from falling and hurting people under non working conditions.
3. Manually open the tamping machine, the upper clamping flap of the tamping machine will be opened under the action of hydraulic pressure, and the transmission unit will drive the eccentric wheel to rotate, and the tamping hammer will fall. Driven by the eccentric wheel, the tamping hammer will move back and forth up and down (the tamping hammer is all driven by gravity in the falling process, and the rising process is driven by the friction plate on the eccentric wheel stepping up the tamping hammer). The automatic feeder has been adding coal in this process.
4. After the tamping hammer works for 5 ~ 7 minutes, the coal cake in the coal loading truck has been basically in place. At this time, the limit sensor on the top of the tamping machine receives the sensing signal of the rising tamping hammer, and the feeder and tamping machine stop automatically.
5. After all the tamping hammers stop, the upper tightening flap of the tamping machine will automatically tighten, and the tamping hammer will rise under the drive of the eccentric wheel. (the tightening flap is composed of two steel parts with about 1 / 4 circle, one on each side, which can be opened during the rising process of the tamping hammer, and the tightening flap will automatically tighten when the tamping hammer is about to fall under the action of gravity.) All tamping hammers will stop automatically after receiving the position.
