Specifically, the present embodiment provides a stirring apparatus, such as a stirring tank, which is known to drive a transmission device through a driving unit and finally drive a central shaft 3 to rotate, such as a motor drives the central shaft 3 to rotate through a speed reducer, and a stirring member on the central shaft 3 rotates in the stirring apparatus to stir liquid, most stirring members in the prior art are single stirring blades, one of the core innovation points of the present embodiment is a passive adaptive-changing stirring assembly 4, the stirring assembly 4 has a plurality of, such as three, four or even more, the plurality of stirring assemblies 4 are arranged at different axial positions on the central shaft 3, each stirring assembly 4 includes a supporting sheet 4.1, a blade 4.2 and an elastic member 4.3, wherein the supporting sheet 4.1 is a fixed structure, one end of which is fixedly connected, such as being inserted, screwed, or welded to the central shaft 3, the supporting sheet 4.1 is arranged along a radial surface of the central shaft 3, that is, the side (thickness side) of the plate of the support sheet 4.1 with a very small area is cut instead of stirring the liquid to be stirred when rotating, so that the support sheet 4.1 has substantially no stirring effect. The support sheet 4.1 is mainly used for supporting, the blades 4.2 are used for stirring, the blades 4.2 are rotatably connected to the long sides of the support sheet 4.1 at one side of the long sides, namely the blades 4.2 can rotate relative to the support sheet 4.1, the elastic members 4.3 connect the blades 4.2 and the support sheet 4.1, the support sheet 4.1 is arranged along the radial surface of the central shaft 3, the blades 4.2 have the moving tendency of being attached to the support sheet 4.1 when being pressed by the circumferential liquid flow, when stirring, the blades 4.2 stir the liquid so that the liquid is pressed by the circumferential liquid flow, at the moment, the blades rotate to be attached to the support sheet 4.1 under the pressure, so that the projection of the blades 4.2 on the central shaft plane changes, as shown in fig. 1-5, the stirring effect of the blades 4.2 is basically determined by the projection area on the central shaft plane, and in the state of fig. 1 and 3, the width direction of the blades 4.2, the projected area of the blade 4.2 on the central axis plane is the largest, the stirring effect is the largest, and the pressure is the larger, while in fig. 2 and 5, the width direction of the blade 4.2 is arranged obliquely to the central axis, the projected area of the blade 4.2 on the central axis plane is the smallest, the stirring effect is the smallest, and the pressure is the smaller.

In the stirring process, the viscosity changes, and the greater the resistance brought to the blade 4.2 by the liquid flow at the same rotating speed, in this embodiment, the blade 4.2 is movable, and the pressure received by the blade in the moving process changes, so that in the process of changing the viscosity, the pressure received by the blade 4.2 is automatically adjusted through movement, and if the pressure received by the blade 4.2 is increased as the viscosity is increased, the projection area on the central axis plane is reduced through the rotation of the blade, so as to reduce the received pressure, and vice versa, so that in the process of changing the viscosity in real time, the resistance received by the stirring component 4 does not change greatly, so as to reduce the wear to the driving system, and prolong the service life of the driving system.
