[0040] Specifically, slurry is injected into the interior of the storage barrel 3 through the liquid injection valve 19, and then the blower 8 is started to extract the air flow filtered by the filter housing 11, effectively preventing larger particles from entering the interior of the blower 8. At the same time, the heating box 10 is used to heat the air, so that the filtered and heated air flow is ejected through the conveying pipe 12 and the annular spray pipe 13, thereby uniformly mixing and heating the slurry inside the storage barrel 3. By means of the servo motor 4 driving the rotating column 5, the plurality of stirring blades 6 are rotated, so as to stir the slurry inside the storage barrel 3, avoiding the slurry from cooling and solidifying after being used for a period of time, thereby reducing the fluidity of the slurry and ensuring that the slurry can be placed for a long time. During cleaning, the air flow ejected through the annular spray pipe 13 improves the mixing effect of the cleaning liquid and water inside the storage barrel 3, thereby enhancing the cleaning effect, and finally significantly improving the working efficiency.

[0041] Referring to Figure 1 、 Figure 3 and Figure 5, the grouting mechanism 2 includes a hydraulic rod 201. The right side of the hydraulic rod 201 is fixedly connected to the left top of the housing 1. The bottom end of the hydraulic rod 201 is fixedly connected to a displacement column 202. The bottom end of the displacement column 202 is fixedly connected to a cross-groove housing 203. The inner top wall of the cross-groove housing 203 is fixedly connected to an electric telescopic rod 204. The bottom end of the electric telescopic rod 204 is fixedly connected to a cross rod 205. The outer side of the cross rod 205 is slidably connected to the outer wall of the cross-groove housing 203. The outer wall of the cross rod 205 is fixedly connected to a sealing housing 206. The bottom wall of the cross-groove housing 203 is fixedly connected to a grouting pipe 207. The front end of the grouting pipe 207 is communicated with a pressure pipe 209. A pressure conveying device 210 is fixedly installed in the middle of the pressure pipe 209. The right end of the pressure pipe 209 is communicated with the left side of the storage barrel 3;

[0042] Specifically, by starting the hydraulic rod 201, the driving displacement column 202 is displaced downward, thereby realizing the adjustment of the depth of the grouting pipe 207 entering the soil, enabling the grouting work to be adjusted at different depths. At the same time, the electric telescopic rod 204 drives the cross rod 205 to slide inside the cross-groove housing 203, achieving the opening and closing operation of the sealing housing 206, that is, opening or closing the grouting pipe 207. The purpose is to protect the grouting pipe 207 and prevent it from being blocked by large particles in the ground, which affects the normal progress of the grouting work. If large particles in the ground enter the grouting pipe 207 in advance, it will cause the slurry to be unable to flow and grout.

[0043] Refer to Figure 2 , Figure 4 and Figure 5 , the front side of the housing 1 is fixedly connected to a control switch 15. The control switch 15 is electrically connected to the servo motor 4, the blower 8, the hydraulic rod 201, and the electric telescopic rod 204 respectively; a rubber ring 14 is fixedly installed on the outer wall of the conveying pipe 12. The outer wall of the rubber ring 14 is fixedly connected to the front bottom end of the housing 1; both the front and rear sides of the housing 1 are fixedly connected to two support seats 17. The bottom walls of the multiple support seats 17 are all fixedly installed with universal wheels 18;

[0044] Specifically, through the control switch 15 electrically connected to the servo motor 4, the blower 8, the hydraulic rod 201, and the electric telescopic rod 204 respectively, the control switch 15 can turn on and off the device. Through the rubber ring 14, the connection of the conveying pipe 12 can be protected, thereby increasing the service life of the conveying pipe 12. Through the support base 17 and the universal wheels 18, the device can be easily moved, improving the flexibility of the device. The model of the servo motor 4 used in the present utility model is MHMF042L1U2MMBDLN25, the model of the blower 8 is the axial flow fan T4-72, the model of the hydraulic rod 201 is GYCD-110 / 750, the model of the electric telescopic rod 204 is JS-TGZ-U1-100MM, and the model of the control switch 15 is lw2.

[0045] Referring to Figure 1 、 Figure 3 and Figure 5 , a viewing window 16 is fixedly installed on the outer shell 1, and the outer walls of the viewing window 16 are all designed to be smooth; a plurality of transverse grooves 7 are provided on one side of each of the plurality of stirring blades 6, and the plurality of transverse grooves 7 are arranged at equal intervals symmetrically; a vertical cone 208 is fixedly connected to the bottom wall of the grouting pipe 207, and the bottom wall of the vertical cone 208 is provided with a curved surface.

[0046] Specifically, through the viewing window 16, it is convenient to observe the inside of the device. Through the plurality of transverse grooves 7, the stirring effect of the stirring blades 6 is improved, and the uniformity of the slurry is increased. Through the vertical cone 208, the blocking effect of the soil on the grouting mechanism 2 is reduced, facilitating the grouting mechanism 2 to penetrate deep into the soil.

[0047] Working principle: When starting to use, slurry is injected into the interior of the storage barrel 3 through the liquid injection valve 19, and then the blower 8 is started to extract the air flow filtered by the filter housing 11, effectively reducing the entry of larger particles into the interior of the blower 8. At the same time, the air heated by the heating box 10 is used to make the filtered and heated air flow spray out through the delivery pipe 12 and the annular nozzle 13, so that the heated and filtered air flow uniformly mixes and heats the slurry inside the storage barrel 3. In cooperation with the servo motor 4 driving the rotating column 5, multiple stirring blades 6 rotate, so that the slurry is stirred inside the storage barrel 3, avoiding the situation that the slurry cools and solidifies after being used for a period of time, reducing the fluidity of the slurry, and thus achieving the purpose of long-term placement and use. At the same time, when cleaning, the air flow sprayed out through the annular nozzle 13 improves the mixing effect of the cleaning liquid and water inside the storage barrel 3, thereby enhancing the cleaning effect, ultimately improving the work efficiency. And by driving the displacement column 202 to move downward by the hydraulic rod 201, the depth of the grouting pipe 207 entering the soil can be adjusted. Thus, by driving the cross rod 205 to slide inside the cross groove housing 203 by the electric telescopic rod 204, the sealing shell 206 can be opened or closed, so that the grouting pipe 207 is opened or sealed, achieving the purpose of protecting and sealing the grouting pipe 207, avoiding the premature entry of larger particles in the ground into the interior of the grouting pipe 207, resulting in its blockage and affecting the progress of the grouting work, and thus improving the grouting effect.
