Liquid spore bacterium spraying device for microbial fertilizer production

The utility model belongs to the technical field of liquid spore bacterium spraying, particularly relates to a liquid spore bacterium spraying device for microbial fertilizer production, and aims to solve the problem that non-uniform stirring of a fertilizer is easily caused by fixed-point stirring when the fertilizer is stirred, and adopts the following scheme that the liquid spore bacterium spraying device comprises a base, a reciprocating mechanism is arranged in the support, a first rotating column and a second rotating column are rotationally connected to the support, one end of the first rotating column and one end of the second rotating column are fixedly connected with a first belt wheel and a second belt wheel respectively, the same belt is in transmission connection between the first belt wheel and the second belt wheel, and a polygonal groove is formed in the second rotating column. A first spring is arranged in the polygonal groove, a polygonal block is slidably connected into the polygonal groove
