[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] See also Figures 1 to 5 , the utility model provides a technical solution:

[0024] A device for filling cracks in building walls comprises a support frame 1, a top support plate 2 is fixedly mounted on the top of the support frame 1, a bottom support plate 3 is arranged at the bottom of the support frame 1, a filling head 4 is arranged at the bottom end of the bottom support plate 3, the filling head 4 has a triangular cross-section, a material pipe 8 is detachably mounted on the support frame 1, a connecting port 5 connected to the outlet of the material pipe 8 is fixedly mounted on the bottom support plate 3, the connecting port 5 is connected to the filling head 4 via a feeding hose 6, a discharge port 7 is provided on the bottom surface of the filling head 4, and an extrusion mechanism for extruding material is arranged on the top of the top support plate 2.

[0025] See also Figure 3 and Figure 4 The discharge port 7 is located at the lowest end of the filling head 4 and has the same width as the inner width of the filling head 4, so that the filling head 4 can be inserted into the crack and discharge the material uniformly and in large quantities, thereby improving the filling efficiency and filling effect.

[0026] See also Figure 4 and Figure 5 The material tube 8 is made of transparent material, which makes it easy to observe the remaining amount of filling material, and limiting protrusions 18 are symmetrically arranged on both sides of the top. At the same time, limiting grooves 17 matching the limiting protrusions 18 are symmetrically arranged at both ends of the top support plate 2, which can make the material tube 8 more stable and avoid rotation when extruding the filling paint.

[0027] See also Figure 1 and Figure 2 The extrusion mechanism includes a push plug 9 arranged inside the material pipe 8 for extruding the material, a fixed support plate 11 arranged just above the push plug 9, a screw rod 12 is rotatably connected between the two ends of the fixed support plate 11 and the two ends of the top support plate 2 through bearings, a push plate 10 is movably installed between the screw rods 12, the push plate 10 is fixedly installed on the top of the push plug 9, and nuts 13 are fixedly installed at both ends of the push plate 10, and the nuts 13 are threadedly connected to the screw rod 12;

[0028] Among them, a servo motor 14 is fixedly installed at the center of the top surface of the fixed support plate 11, and a driving gear 15 is fixedly installed at the power output end of the servo motor 14 through the fixed support plate 11, and a driven gear 16 is fixedly installed at the top of the screw rod 12, and the driving gear 15 is meshed with the driven gear 16.

[0029] See also Figure 1 and Figure 2 The distance between the fixed support plate 11 and the top support plate 2 is greater than the length of the push plug 9, so that the push plug 9 can be pulled up and separated from the material pipe 8, making it convenient to replace the material pipe 8 or add filling materials.

[0030] It is worth mentioning that after the filling is completed, since the cross-section of the filling head 4 is triangular, the filling head 4 can also be used as a trowel to smooth the filling paint, killing two birds with one stone, which is very convenient, has a better filling effect, and high filling efficiency.
