Liquid bacterium adding equipment for producing biological organic bacterial manure

The utility model provides liquid bacterium adding equipment for producing biological organic bacterial manure. The equipment comprises a bacterium adding device and a bacterium mixing device. The bacterium adding device comprises a liquid bacterium tank and a pressure tank. The bacterium mixing device comprises a roller, a bacterium outlet is communicated with the roller through a bacterium adding pipeline, and the roller is driven by a second rotary drive mechanism to move. The inner wall of the roller is provided with atomizers for atomizing liquid bacteria, a washing port is formed in the lower portion of the liquid bacterium tank, a feed pump and a first valve are arranged on the bacterium adding pipeline, the portion, between the feed pump and the first valve, of the bacterium adding pipeline is communicated with a washing pipeline. The washing pipeline is communicated with a water tank. A second valve is arranged on the washing pipeline. Probiotics cenobium is evenly sprayed to organic manure, the probiotics cenobium and the organic manure can be fully mixed in the roller, and the quality of the produced biological organic bacterial manure is good, and production efficiency is high.
