[0002] At present, water retention is one of the important performance indicators of mortar, which determines the performance of mortar. Therefore, before actual use, the production site or the mortar user needs to test the water retention of the mortar.

[0003] After searching, the publication number: CN219016320U announced a mortar water retention tester, move the positioning columns downward until the top is lower than the top surface of the circular test mold, that is, lower than the top surface of the side wall of the test mold, and then pour the mortar into the circular test mold and fill the circular test mold with the mortar, use a scraper to scrape off the excess mortar, move the positioning columns upward until the top is higher than the top surface of the circular test mold, first place the metal mesh in the accommodating cavity formed by the four positioning columns, the metal mesh is close to the top surface of the side wall of the test mold and the mortar, and then stack multiple qualitative filter papers on the metal mesh. The setting of the four positioning columns allows multiple qualitative filter papers to be stacked neatly, cover the qualitative filter paper with a watertight sheet, and then use a pressing block to press on the watertight sheet, let it stand for minutes, remove the pressing block and the watertight sheet, observe the changes in the qualitative filter paper, and determine whether the number of qualitative filter papers is appropriate.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following technical defects that need to be improved:

[0005] This device requires the removal of excess mortar after the mortar is poured into the mold, which is a time-consuming operation. The pressure plate is pressed on the impermeable sheet, and the water retention of the mortar is determined by the changes in the filter paper after standing for two minutes. The standing time of this process is short, and the qualitative filter paper does not fully absorb the moisture of the mortar, thereby reducing the test effect. Utility Model Content

[0006] The present application provides a mortar water retention test device to improve the following technical problems:

[0007] The existing device has too short a static time after squeezing out the moisture, so that the traditional qualitative filter paper does not fully absorb the mortar moisture, thereby reducing the test effect.

[0008] The present application provides a mortar water retention test device, which adopts the following technical solution:

[0009] A mortar water retention test device includes a dry water retention test mechanism, which includes a support platform, a mixing tank, a feed frame, an electromagnetic discharge valve, a weighing platform, a barrel and a drying box. The feed frame is fixedly connected to the lower end of the discharge port of the mixing tank, the electromagnetic discharge valve is clamped at the bottom of the feed frame, the weighing platform is arranged at the lower end of the feed frame, the support platform is slidably connected to the outside of the weighing platform, the barrel is clamped at the middle of the top end of the weighing platform, the drying box is arranged on the outside of the support platform, and a mixing assembly is also arranged inside the mixing tank.

[0010] In an achievable technical solution of the present application, the mixing assembly includes a stepper motor, a stirring shaft and mixing blades. The motor shaft of the stepper motor is fixedly connected to the top of the stirring shaft through a coupling, and the mixing blades are welded and fixed to the outside of the stirring shaft.

[0011] In an achievable technical solution of the present application, a propulsion cylinder and a push rod are also provided on one side of the support platform, the piston end of the propulsion cylinder is fixedly connected to one side of the push rod, and the outer side of the push rod is fixedly connected to the surface of the weighing platform.

[0012] In a feasible technical solution of the present application, a Teflon film is also attached to the upper end of the barrel.

[0013] In a feasible technical solution of the present application, a weighing sensor is threadedly connected to the inner surface of the weighing platform close to the barrel.

[0014] In an achievable technical solution of the present application, the opposite side surfaces of the weighing platform and the supporting platform are further provided with straight sliding rails and limiting clamping plates with sizes matching each other.

[0015] In a feasible technical solution of the present application, a plurality of groups of storage tables are evenly spaced inside the drying box.

[0017] 1. The top cover of the mixing tank can be opened, and the mortar and water in a ratio of 4-5:1 can be put into the mixing tank. In order to avoid uneven mixing of the mortar and cause internal lumps, the device can automatically start the stepper motor on the top through the control end, and its motor shaft drives the stirring shaft to rotate, and the stirring shaft drives the multiple sets of mixing fan blades welded on the outside to rotate, thereby accelerating the mixing rate of the mortar and water to ensure the mixing effect of the mortar; then the staff will cover the outside of the barrel with a Teflon film to prevent the mixed mortar from sticking to the barrel, thereby improving the accuracy of the test;

[0018] 2. During the unloading process, the weighing sensor located on the inner side of the weighing platform can monitor the weight of the top barrel in real time. Through the pre-set rated mortar addition, when the barrel reaches the specified weight, the electromagnet of the electromagnetic unloading valve at the bottom of the feed frame is powered off and the valve disc is pushed back to its original position by the spring, thereby completing the quantitative unloading of the mortar, which is convenient for the separate detection of multiple groups of data; at the same time, the outer propulsion cylinder is started, and its piston end pushes the outer push rod, and the push rod pushes the weighing platform. The weighing platform pushes the weighing platform and the barrel to the outside of the support platform through the sliding cooperation of the built-in straight sliding track of the support platform through two groups of limit cards. The staff opens the cover of the drying box, takes out the barrel and places it on the internal storage table, controls the temperature at about 105℃ and heats it for 10 minutes, then takes out the barrel, puts the barrel back on the weighing platform and weighs it after subtracting the weight of the barrel.
