[0014] The beneficial effects of the embodiments of the present utility model are as follows:

[0015] (1) The cement mortar mixer includes a frame, a mixing pot with an opening, a mixing component, a water tank and a sand tank. During the experiment, the experimenter first added cement into the mixing pot, and then added a certain amount of water and standard sand into the water tank and the sand tank according to the ratio. The water and standard sand gradually flowed into the mixing pot from the water outlet pipe and the sand outlet pipe facing the opening respectively. The water and standard sand gradually flowed into the mixing pot, and the mixing component was started at the same time to continuously stir the cement, water and standard sand in the mixing pot.

The water inlet of the peristaltic pump is connected to the water tank through a transparent rubber hose, the water outlet of the peristaltic pump is connected to the water outlet through a transparent rubber hose, and the output end of the motor is connected to the peristaltic pump. The experimenter starts the power supply, and the motor receives the working signal to drive the peristaltic pump. When the roller of the peristaltic pump moves in the pump pipe, it squeezes the transparent rubber hose to form a vacuum to absorb water, and then continues to roll to squeeze the water into the outlet pipe. The water flows into the mixing pot in intervals. By setting the peristaltic pump to gradually add water to the mixing pot at intervals, it further helps the experimenter to control the consistency of the cement mortar and improve the accuracy of the experiment.

The water tank is connected to an external water source through a valve port pipeline. When the water level in the water tank is at a specified position, the float floats on the water surface and the valve port is closed. When the pump body extracts a certain amount of water, the water level drops, and the float drops along with the water level. The valve port opens, and the external water source flows into the water tank from the valve port, so that a certain amount of water is maintained in the water tank. Experimenters do not need to frequently add water to the water tank during multiple experiments, thereby improving the continuity of the experiment and improving the experimental efficiency.

[0018] (4) Furthermore, the water tank is provided with a temperature sensor and an observation window. The test end of the temperature sensor extends into the water in the water tank. When the pump draws water to the outlet pipe and flows into the mixing pot, the experimenter observes the temperature of the water drawn from the water tank and added to the mixing pot in real time through the observation window. The experimenter records the experimental data, calibrates the measurement results, and reduces the error caused by the water temperature to the experiment. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] When this embodiment is working:

[0033] A fixed amount of water is stored in the water tank 4. The experimenter adds a fixed amount of cement to the mixing pot 2 and a fixed amount of standard sand to the sand pot 5. The power is turned on, and the motor 43 receives the working signal to drive the peristaltic pump. When the roller of the peristaltic pump moves in the pump tube, it squeezes the transparent rubber hose, creating a vacuum to suck in water, and then continues to roll to squeeze the water into the water outlet pipe 41.
