The invention discloses a stirring device. The stirring device comprises a main machine box and a motor box, wherein a first motor and a second motor are installed in the motor box, the top end of themain machine box is provided with a warning device by virtue of a connecting rod, the bottom end of the main machine box is provided with a base, a feeding cavity, a guiding cavity, a stirring cavityand a material outlet are successively arranged inside the main machine box from top to bottom in a communication manner, the material outlet extends to the outer side of the device, and the top endof the feeding cavity is provided with a top cover by virtue of screws. The stirring device is provided with a stirring impeller, stirring blades are used for stirring trichosanthes kirilowii in the longitudinal direction, and square through holes are used for limiting the stirring blades to avoid the loosening situation of the stirring blades due to the rotation of the stirring impeller, so thatthe blades can be demounted, the connection of bolts and nuts are not influenced by the rotation of the stirring impeller, the stirring blades can be installed by virtue of the bolts in two opposite directions, the transverse stirring area can be increased, the alternating cutting teeth contact the trichosanthes kirilowii, the cutting is more thorough, and the working efficiency is increased.
