[0032] In addition, the materials to be tested and the microbial strains are mixed and loaded into the storage barrel 5. During filling, the third motor 23 drives the conveying rod 24 to rotate and drives the auger blades to convey each material into the filling barrel 3, and then the first motor 11 is turned on. The first motor 11 drives the second rotating shaft 8 to rotate, and drives the second bevel gear to rotate. The second bevel gear drives the first bevel gear 9 to rotate so that the first rotating shaft 7 rotates. The first rotating shaft 7 drives the spiral blades to rotate, loosening the material at the discharge position of the filling barrel 3 to reduce the possibility of blockage. When the first motor 11 rotates, it drives the transmission wheel 21 on the second rotating shaft 8 to rotate, and drives the transmission wheel on the connecting shaft 10 under the action of the belt 22. 21 rotates, thereby causing the disc 12 to rotate. When the disc 12 rotates, it drives the rotating rod 13 to rotate between the disc 12 and the pull rod 15. When the connection between the disc 12 and the rotating rod 13 rotates from the top to the bottom, the rotating rod 13 drives the pull rod 15 downward, and the pull rod 15 pushes the piston 14 to apply pressure to the inside of the filling cylinder 3, so that the material enters the mixing cylinder 1 from the filling cylinder 3 to react. When the piston 14 is working, one end of the storage cylinder 5 is in a sealed state, and with the transportation of the second auger blade 25, the material enters the mixing cylinder 1 from the filling cylinder 3 as much as possible under the action of pressure, thereby eliminating the need for frequent manual filling and reducing the labor intensity of the staff.
