[0023] like Figure 1-5As shown, the utility model provides a technical solution: a structural crack grouting device for a building construction project, comprising a bottom plate 1, the bottom of the bottom plate 1 is fixedly connected with universal wheels with brakes near the four corners, and the top of the bottom plate 1 is fixedly connected with a push rod, the top of the bottom plate 1 is fixedly connected with a barrel 2, and the barrel 2 is fully enclosed, an opening is opened on the front side of the barrel 2, and a movable door 16 is movably connected to the opening through a hinge, a sealing ring is fixedly connected to the inner side of the movable door 16, a rotating rod 3 is arranged in the barrel 2, and a plurality of evenly distributed stirring rods 4 are arranged on the rotating rod 3, a fixed pipe 11 is fixedly connected to the left side of the barrel 2, and the fixed pipe 1 1 is fixedly connected with a motor 13, the top of the rotating rod 3 passes through the fixed pipe 11 and extends to the outside and is fixedly connected with the output end of the motor 13, the bottom plate 1 is fixedly connected with an air pump 10, the air pump 10 is fixedly connected with an air pipe, and the air pipe runs through the barrel 2, a movable plate 9 is arranged in the barrel 2, a first cylinder 8 is fixedly connected with the top of the barrel 2, and the telescopic end of the first cylinder 8 extends into the barrel 2 and is fixedly connected with the movable plate 9, a grouting pipe 7 is arranged on the outside of the barrel 2, the grouting pipe 7 is integrally formed as a pipe body, one end of the grouting pipe 7 is conical, and a discharge port is opened, and the other end is closed, and a feed pipe 6 is connected between the grouting pipe 7 and the barrel 2.

[0024] According to the overall structure of the device, the movable door 16 is opened, and raw materials are added into the barrel 2. The movable door 16 is closed, and the motor 13 is started. The motor 13 drives the rotating rod 3 to rotate, and drives the stirring rod 4 to rotate to stir the raw materials to form a slurry. As the stirring continues, the air in the slurry is discharged, and the air pump 10 is started to evacuate the barrel 2 to discharge the air from the barrel 2. When grouting, the device can be moved to the crack by the universal wheel and the push rod, and the universal wheel is provided with a brake to fix the device at the current position. Then the motor 13 is stopped, and the rotating rod 3 and the stirring rod 4 are put into the fixed tube 11. Then the discharge port of the grouting tube 7 is inserted into the crack. The first cylinder 8 is started. The first cylinder 8 pushes the movable plate 9 to extrude the slurry from the discharge pipe 5, and feeds it into the grouting tube 7 from the feed pipe 6. The slurry is discharged from the discharge port at the tapered end into the crack to complete the grouting. As the slurry is continuously extruded, the crack is filled.

[0025] like Figure 2 As shown, the fixed tube 11 is connected to the inside of the barrel 2 and is inclined. The end of the fixed tube 11 away from the barrel 2 is closed. The motor 13 is fixedly connected to the closed end of the fixed tube 11. The closed end inside the fixed tube 11 is fixedly connected to the second cylinder 12. The output shaft of the motor 13 extends into the fixed tube 11 and is fixedly connected to the second cylinder 12. The telescopic end of the second cylinder 12 is fixedly connected to the rotating rod 3. The bottom end of the rotating rod 3 is fixedly connected to a spherical rubber block.

[0026] By setting an oblique fixed tube 11, the rotating rod 3 and the stirring rod 4 can be stored, and the slurry can be prevented from flowing into the fixed tube 11 during the stirring process. The telescopic end of the second cylinder 12 is connected to the rotating rod 3. When the second cylinder 12 contracts, the rotating rod 3 can be put into the fixed tube 11, so that the rotating rod 3 and the stirring rod 4 can be moved away from under the movable plate 9, making it easier for the movable plate 9 to press down to squeeze the slurry out of the barrel 2.

[0027] like Figure 3 As shown, a plurality of evenly distributed grooves are provided around the stirring rod 4, one end of the stirring rod 4 is inserted into the groove, and a groove is provided at one end of the stirring rod 4 close to the rotating rod 3, a rotating shaft passes through the groove, and the rotating shaft is movably connected to the groove, and a torsion spring is sleeved on the rotating shaft.

[0028] The stirring rod 4 can be deflected by the rotating shaft, and the deflected stirring rod 4 can be stored by the groove, so that the stirring rod 4 is hidden in the rotating rod 3, which is convenient for the rotating rod 3 to be stored in the fixed tube 11. When the stirring rod 4 is retracted, the torsion spring will be compressed, so that when the rotating rod 3 is extended, the stirring rod 4 can be automatically unfolded by the torsion spring.

[0029] like Figure 1 As shown, there are several grouting pipes 7, and several linearly distributed discharge pipes 5 are fixedly connected to the outside of the barrel 2 near the bottom, and valves are provided on the discharge pipes 5. Feed pipes 6 are respectively connected between the several grouting pipes 7 and the several discharge pipes 5.

[0030] By providing a plurality of grouting pipes 7 , a plurality of cracks can be filled at the same time, and the slurry conveying of the plurality of grouting pipes 7 is performed separately, so that when one of the grouting pipes 7 is damaged, the use of other grouting pipes 7 will not be affected.

[0031] like Figure 5 As shown, the feed pipe 6 is a plastic hose, and quick-connect connectors 17 are provided at both ends of the feed pipe 6 , which are respectively connected to the discharge pipe 5 and the grouting pipe 7 through the quick-connect connectors 17 .

[0032] The quick-insert connector 17 can be used to quickly connect and disconnect the hose, the grouting pipe 7 and the discharge pipe 5, so that damaged parts can be quickly disassembled and replaced, avoiding damage to parts that reduce grouting efficiency and facilitating maintenance.

[0033] like Figure 1 , 4 As shown, an arc plate 14 is fixedly connected to the outside of the barrel 2, and a plurality of evenly distributed insertion holes are opened on the arc plate 14. L-shaped insertion rods 15 are fixedly connected to the outside of a plurality of grouting pipes 7, and the insertion rods 15 are inserted into adjacent insertion holes.

[0034] The grouting pipe 7 is hung on the outside of the barrel 2 by plugging the plug rod 15 into the plug hole, so that a plurality of grouting pipes 7 are neatly arranged for direct taking, and the taking and placing are convenient and quick.

[0035] Working principle: When in use, connect the device to an external power source, open the movable door 16, pour the raw material into the barrel 2 through the opening, and close the movable door 16, then start the motor 13, the motor 13 drives the second cylinder 12 to rotate, and drives the rotating rod 3 and the stirring rod 4 to rotate, stir the raw material to form a slurry, and at the same time, the air pump 10 evacuates the barrel 2 to discharge the air in the barrel 2, and as the stirring proceeds, the bubbles in the slurry are discharged and drawn out of the barrel 2 along with the air, when grouting is required, stop the motor 13, start the second cylinder 12, and the second cylinder 12 contracts to rotate the rotating rod 3 is brought to the fixed pipe 11. As the rotating rod 3 is retracted, the stirring rod 4 is blocked by the inner wall of the barrel 2 and deflected and retracted into the groove, thereby causing the rotating rod 3 to be retracted into the fixed pipe 11. Then, the grouting pipe 7 is lifted upward to separate the insertion rod 15 from the insertion hole to remove the grouting pipe 7. Then, the tapered end of the grouting pipe 7 is inserted into the crack, and the valve of the discharge pipe 5 connected to the grouting pipe 7 is opened, and the first cylinder 8 is started. The first cylinder 8 is extended to press the movable plate 9 downward, exerting pressure on the slurry, squeezing the slurry out of the discharge pipe 5, and feeding it into the grouting pipe 7 through the feeding pipe 6, and then injected into the crack for filling.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
