A handle 11 is fixedly connected to the lower end of the circumferential side of the outer tube 1, and a disc seat 12 is fixedly connected to one end of the outer tube 1. The nozzle 2 is detachably fixed to one side of the disc seat 12. The setting of the handle 11 helps the user to smoothly perform the grouting operation. Figure 2 As shown, the other end of the outer cylinder 1 is provided with a feeding assembly 4 for stirring and pushing the slurry, and the inner part of the outer cylinder 1 is detachably fixed with a material placement assembly 5 for storing the slurry, and the material placement assembly 5 includes an inner cylinder 51 and a sealing gasket layer 52, as shown in FIG. Figure 5 and Figure 6 As shown, the inner cylinder 51 is a hollow double-layer sleeve cylinder structure, and a sealing gasket layer 52 is arranged at the interlayer gap of the inner cylinder 51. The sealing gasket layer 52 is cylindrical, and the sealing gasket layer 52 is directly and tightly fitted with the inner cylinder 51. The sealing gasket layer 52 is inserted into the interlayer gap of the inner cylinder 51, so as to seal and shield the hollow part of the inner cylinder 51, and the slurry used for grouting can be stored in the cylindrical cavity formed by the sealing gasket layer 52. When the outer cylinder 1 is cleaned, the inner cylinder 51 is taken out from the outer cylinder 1, the sealing gasket layer 52 is pulled out, and the inner cylinder 51 and the sealing gasket layer 52 are rinsed. The hollow structure allows water to more easily enter every corner of the interior, and the cleaning is more thorough, avoiding the slurry residue solidification and then causing blockage. A through hole is opened at the center position of the central cylinder of the inner cylinder 51, and a sleeve 511 is fixedly connected to the center of the closed end of the inner cylinder 51. The inner diameter of the sleeve 511 matches the outer diameter of the butt pipe 14, as shown in FIG. Figure 7 As shown, a through hole is opened at the center of the disc seat 12, a bottom tube 13 is fixed to the outside of the through hole of the disc seat 12, and a butt tube 14 is fixedly connected to the free end of the bottom tube 13, and the outer diameter of the butt tube 14 is smaller than the outer diameter of the bottom tube 13. Figure 3 As shown, a plurality of sleeves 15 are fixed around the periphery of the bottom tube 13, and a spring 151 is fixedly connected inside the sleeve 15. Figure 4 and Figure 7 As shown, a plurality of contacts 512 are fixed around the periphery of the sleeve 511, and the contacts 512 extend into the interior of the sleeve 15 and abut against the spring 151. When the cleaned inner cylinder 51 is installed in the outer cylinder 1, the contacts 512 are first aligned with the sleeve 15, and the butt tube 14 is aligned with the sleeve 511 at the same time, and the inner cylinder 51 is pressed laterally so that the contacts 512 squeeze the spring 151, so that the inner cylinder 51 completely enters the inner cavity of the outer cylinder 1. At this time, the sleeve 511 is aligned with the bottom tube 13, and the spring 151 resets and pushes the inner cylinder 51 in the reverse direction, so that the bottom tube 13 and the end wall of the outer cylinder 1 clamp and fix the inner cylinder 51, and the disassembly and installation process of the inner cylinder 51 is simple and fast.

[0030] Adopting the utility model, such as Figure 2 and Figure 3 As shown, when the slurry in the device is used up, the outer cylinder 1 needs to be cleaned and new slurry needs to be added. The top cover 3 is removed, and the inner cylinder 51 is pushed toward the disc seat 12 so that the inner cylinder 51 can be taken out of the outer cylinder 1. The sealing gasket layer 52 in the inner cylinder 51 is pulled out, and the inner cylinder 51 and the sealing gasket layer 52 are rinsed. The hollow structure allows water to more easily enter every corner of the interior, and the cleaning is more thorough, avoiding the slurry residue from solidifying and causing blockage. When the cleaned inner cylinder 51 is installed in the outer cylinder 1, the contact 512 is first aligned with the sleeve 15, and the butt pipe 14 is aligned with the sleeve 511, and the side press is pressed. The inner cylinder 51 is pressed so that the contact 512 squeezes the spring 151, so that the inner cylinder 51 completely enters the inner cavity of the outer cylinder 1. At this time, the sleeve 511 is aligned with the bottom tube 13, and the spring 151 resets and pushes the inner cylinder 51 in the opposite direction, so that the bottom tube 13 and the end wall of the outer cylinder 1 clamp and fix the inner cylinder 51.
