When the infrared light source is particularly used, before the initial test is started, the controller 12 sends out an electric signal to control the infrared emitter 10, the infrared receiver 11 and the driving motor 6025 to start, the infrared emitter 10 emits an infrared light beam, the infrared light beam approaches the upper end face of the measuring cup 3, at the moment, the infrared receiver 11 can receive the light beam emitted by the infrared emitter 10 and send out an electric signal to the controller 12 so as to indicate that the infrared light beam is not shielded, the measuring cup 3 is not fully filled, and meanwhile, the inner expansion assembly 601 and the outer expansion assembly 701 are in a state of clamping and closing the inner threaded hose 402 at the bottom of the conical cylinder 401.
Then, after filling the slurry into one of the three conical cylinders 401, sending an electric signal through the controller 12 to control the driving motor 6025 to start so as to drive the inner expanding assembly 601 to be far away from the inner threaded hose 402, simultaneously, pulling the outer expanding assembly 701 to be far away from the inner threaded hose 402 synchronously through the pulling assembly 702, releasing the clamping closure of the inner threaded hose 402, sending an electric signal through the controller 12 after closing to control the driving motor 6025 to stop rotating, at this time, receiving a signal of 'stopping rotation of the driving motor 6025 motor' sent by the controller 12 by a timing module in the controller 12, indicating that the slurry has started to flow out, taking the timing module in the controller 12 as a trigger point for starting timing, immediately starting timing, and naturally flowing downwards under the action of gravity by the slurry in the conical cylinder 401 filled with the slurry, and discharging the slurry into the measuring cup 3 through the inner threaded hose 402.

After the primary test is completed, the same operation is repeated to perform the secondary test, except that slurry is injected into each of the three conical cylinders 401 to obtain a time T1 required for filling the measuring cup 3 by simultaneously discharging the slurry in the three sample holders 4, and then the time T1 is compared with the discharge time of the standard water sample.
In the secondary test, by simultaneously injecting the slurry into the three conical cylinders 401 and enabling the slurry to flow out synchronously, the error easily generated in the test by using only a single sample holder 4 can be effectively avoided, namely the problem that the local fluidity difference possibly existing in the same batch of slurry due to factors such as uneven stirring, precipitation, temperature gradient, water evaporation and the like is difficult to be completely captured by only a small part of slurry is avoided, so that the data diversity is increased through the synchronous test of the three sample holders 4, and the integral fluidity characteristic of the slurry is more accurately reflected.
After the secondary test is finished, the stability of the slurry can be evaluated by comparing T0 (the outflow time of the slurry in the single sample holder 4) with T1 (the synchronous outflow time of the slurry in the three sample holders 4), if the two are not far apart, the slurry has better stability in terms of fluidity, otherwise, if the difference is obvious, the proportioning or stirring process of the slurry needs to be improved.
