[0029] The specific usage and function of this embodiment are as follows:

[0030] In this utility model, when... Figure 1As shown, when the device body 1 is in use, mortar is poured into the mortar drying box 2. The mortar is supported by the mortar discharge plate 5, which covers the mortar drying pipe 3. The mortar drying pipe 3 is located at the bottom of the mortar. The mortar drying pipe 3 is connected to an external air supply pipe, allowing hot air to enter the interior through the right end of the mortar drying pipe 3. Then, it seeps out evenly from the top permeable ceramic column 4. The microporous structure of the permeable ceramic column 4 ensures that the hot air penetrates the mortar upwards in a dispersed manner, carrying away moisture, while preventing sand particles from clogging the channels. This hot air flow is from bottom to top. The method of directly removing moisture by penetrating the interior of the mortar significantly improves efficiency compared to surface drying. It solves the problem of low drying efficiency caused by hot air only passing over the surface of the mortar. When the dried mortar inside the device body 1 is discharged, the discharge control cylinder 6 is engaged with the discharge lifting column 7 by rotating a tool. This causes the discharge lifting column 7 to descend, simultaneously lowering the upper end of the discharge linkage rod 9. This, in turn, pushes the lower end of the discharge linkage rod 9 to flip the mortar discharge plate 5 downwards, opening it as shown in the image. Figure 5 and Figure 6 As shown, this allows the mortar inside the device body 1 to be discharged downwards quickly, solving the problem that the process of removing the mortar from the device after it has dried is quite cumbersome.

[0031] Example 2: Unlike Example 1, the hexagonal structure of the emission control cylinder 6 can also be set as a regular heptagonal structure. This makes it necessary to use a special tool that works with the regular heptagonal structure to rotate the emission control cylinder 6, thus preventing non-staff members from rotating and adjusting the emission control cylinder 6.

[0032] Example 3: The difference from Example 1 is that the regular hexagonal prism of the anti-detachment circular plate 8 can also be set as a regular heptagonal prism, so that the anti-detachment circular plate 8 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the anti-detachment circular plate 8.
