The novel innovation point of the invention is that: during actual operation, the connecting shaft 10 inputs power, so that the planet gears 12 rotate and revolve around the sun gear 11, the stirring paddles 13 rotate and revolve around the sun gear 11 under the driving of the planet gears 12, materials are rapidly conveyed to the bottom of the stirring container from the upper part of the stirring container, and the materials are conveyed to the bottom of the stirring container and then upwards along the inner wall of the stirring container, so that the materials can form circulation inside the stirring container, the materials can be mixed more rapidly and uniformly, and the production efficiency and the product quality are improved.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
