in one embodiment, as shown in fig. 6, a heating element 42 is further installed inside each stirring rod body 4, and the heating element 42 is used for heating the air flow introduced into the stirring rod body 4, so that the hot air is introduced into the propagation expanding box body 1 along with the air flow, thereby realizing uniform heating of the microbial feed additive and ensuring the temperature requirement for propagation of the microbes; the heating member 42 is an electric heating rod or a PTC heating tube;

in one embodiment, as shown in fig. 1, a filter screen plate 10 located at the bottom is further disposed in the propagation expanding box 1, the bottom end of the jet flow vertical pipe body 6 is connected to the filter screen plate 10, and a liquid outlet pipe body 13 for guiding out the feed liquid is connected to the outer side wall of the propagation expanding box 1; the arrangement of the filter screen plate 10 can ensure that the jet flow vertical pipe body 6 is fixed and can filter impurities in discharged feed liquid, and the feed liquid is led out through the liquid outlet pipe body 13;

the embodiment above discloses an activation propagation device for a microbial feed additive, when the feed additive inside the propagation box body 1 is in a static state, the liquid inlet 72 at the top of the adjusting conduit 7 is arranged inside the supporting pipe body 9, and the liquid inlet 72 is blocked by the inner wall of the supporting pipe body 9, so that the feed liquid stored in the feed liquid storage member 2 cannot enter the inside of the jet flow vertical pipe body 6 through the adjusting conduit 7; when the driving piece drives the rotating rod bodies 3 to rotate, the plurality of stirring rod bodies 4 rotate in the propagation expanding box body 1 along with the rotating rod bodies, the plurality of stirring rod bodies 4 stir the microbial feed additive in the propagation expanding box body 1, the microbial feed additive rotates in the propagation expanding box body 1 and forms a vortex in the center of the propagation expanding box body 1; the liquid level of the microbial feed additive at the side wall of the propagation box body 1 moves upwards, so that the floating piece 8 moves upwards along with the liquid level, the floating piece 8 drives the adjusting guide pipe 7 to move upwards, the upward movement of the adjusting guide pipe 7 firstly enables the liquid inlet 72 to be arranged in the liquid storage component 2, and the adjusting guide pipe 7 is communicated through the liquid inlet 72; then the activating agent in the feed liquid storage component 2 is led into the adjusting conduit 7 through the liquid inlet 72 and is sprayed out to the microorganism feed additive rotating in the propagation expanding box body 1 through the one-way spray opening component; so that the activator can be effectively mixed with the microbial feed additive; the faster the driving part drives the rotating rod body 3 and the stirring rod body 4 to rotate, the higher the rotating speed of the microbial feed additive, so that the larger the centrifugal force at two sides of the microbial feed additive is, the microbial feed additive is extruded to the periphery, the larger the vortex formed by the microbial feed additive in the propagation box body 1 is, the higher the peripheral liquid level moves up, the more the liquid inlet 72 extends into the liquid storage component 2, and the higher the flow rate of the activating agent in the liquid storage component 2 entering the liquid inlet 72 from the liquid inlet 72 is; therefore, the mixing flow of the activating agent and the microbial feed additive and the rotating speed of stirring the microbial feed additive form a matching relationship, so that the mixing uniformity and effect of the activating agent and the microbial feed additive are effectively improved, and the activation and propagation of microorganisms are improved.
