Water-cooling fire grate transmission device

The utility model discloses a water-cooling fire grate transmission device. The water-cooling fire grate transmission device comprises a transmission mechanism, an eccentric mechanism and a vibrating mechanism. The transmission mechanism is in transmission connection with the eccentric mechanism through a belt, the eccentric mechanism is connected with the vibrating mechanism through a transmission rod, the vibrating mechanism comprises a guide shaft and a spring sheet, the guide shaft is connected with a fire grate flake through a vibration component connecting piece, the vibration component connecting piece is installed on the guide shaft, and spring sheet sets are installed on the two sides respectively and are fixed through gland nuts; the guide shaft is in threaded connection with the transmission rod. By means of the water-cooling fire grate transmission device, bonding, bridging and coking of biomass fuel during burning are effectively eliminated, impurities such as burnt ash are stably discharged, the biomass fuel is completely burnt, heat of the biomass fuel is sufficiently used, and a whole water-cooling fire grate is stable and continuous.
