The chain plate dumper works in the organic fertilizer fermentation tank. Tracks are designed on both sides of the fermentation tank. The dumper spans the fermentation tank track and is driven by a motor. The chain plate tipper can move from one fermentation tank to another through the moving crane, and has strong adaptability to the characteristics of fermentation materials. All materials of the dumper are suitable for the environmental corrosion of the organic domestic waste fermentation workshop. In particular, the rake teeth are calcined at high temperature, which is corrosion resistant, wear-resistant and has a long service life.
