[0021] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0022] Example 1

[0023] The construction engineering structure gap grouting device of the present invention comprises a grouting bucket 1.

[0024] Please refer to Figure 1 , Figure 1 The figure is a schematic diagram of the overall three-dimensional structure of a caulking barrel according to an embodiment of the present invention, when half-sectioned. As shown in the figure, the caulking barrel 1 is provided with a feed pipe (not shown) with a solenoid valve to facilitate the addition of concrete slurry into the caulking barrel 1. A drive shaft 7 is rotatably connected to the caulking barrel 1, and a feed auger 2 is fixed to the drive shaft 7. A motor 3, whose output shaft is fixed to one end of the drive shaft 7, is fixed to the outer wall of one end of the caulking barrel 1. A caulking pipe 11 is fixed to the other end of the caulking barrel 1. The caulking pipe 11 can be a retractable flexible pipe or a rigid pipe connected to a flexible pipe, thereby facilitating the grouting operation. The operator only needs to turn on the motor 3, so that the motor 3 drives the feed auger 2 to rotate via the drive shaft 7. When the feed auger 2 rotates, the caulking concrete slurry in the caulking barrel 1 is squeezed out of the caulking pipe 11 and grouting is performed on the building gap.

[0025] Figure 2 This is a schematic diagram of the transmission assembly and crushing blade assembly structure of a protective shell according to an embodiment of the present invention, with the protective shell half-cut. The transmission assembly 6 and crushing blade assembly 4 are mounted on the transmission shaft 7 near the middle of the caulking pipe 11. The transmission shaft 7 drives the crushing blade assembly 4 through the transmission assembly 6. Both the transmission assembly 6 and the crushing blade assembly 4 are located on the side of the feed auger 2 near the caulking pipe 11.

[0026] Based on the above structure, when the motor 3 drives the transmission shaft 7 to rotate, the transmission shaft 7 drives the crushing knife group 4 to rotate through the transmission assembly 6, thereby crushing the larger aggregates (stones, etc.) contained in the concrete slurry in the grouting barrel 1, making the concrete slurry particles smaller, which is more conducive to filling narrow gaps and improving the quality of grouting.

[0027] Figure 3The figure is a schematic diagram of a partial structure of a transmission shaft, agitating blades, and a support rod according to an embodiment of the present invention. The transmission assembly 6 includes a first gear 61 and a second gear 62. The diameter of the first gear 61 is larger than that of the second gear 62. The first gear 61 is fixedly mounted on the transmission shaft 7, and the second gear 62 is meshed with the first gear 61. When the transmission shaft 7 rotates, the first gear 61 is driven to rotate, and when the first gear 61 rotates, the second gear 62 is driven to rotate, thereby driving the crushing blade group 4. This fully utilizes the power output by the transmission shaft 7. By utilizing the fact that the diameter of the first gear 61 is larger than that of the second gear 62, the rotation speed of the second gear 62 is a multiple of that of the first gear 61, thereby making the rotation speed of the crushing blade group 4 a multiple of that of the feeding auger 2, which is more conducive to fully crushing larger aggregates in the concrete slurry.

[0028] A protective shell 8 is also installed in the grouting barrel 1. The protective shell 8 covers the outside of the first gear 61 and the second gear 62. The second gear 62 is rotatably connected to the inner wall of the protective shell 8 through a connecting piece. The protective shell 8 protects the first gear 61 and the second gear 62 to prevent the first gear 61 and the second gear 62 from being damaged by the concrete slurry.

[0029] Among them, the crushing knife group 4 includes a crushing shaft 41 and a crushing knife 42. One end of the crushing shaft 41 rotates through the protective shell 8 and is fixed to one side of the second gear 62. There are multiple crushing knives 42 and they are evenly distributed along the axis direction of the crushing shaft 41. The crushing knife 42 is located outside the protective shell 8. When the second gear 62 rotates, the second gear 62 drives the crushing knife 42 to rotate through the crushing shaft 41, thereby utilizing the power of the transmission shaft 7 to drive the crushing knife 42 to crush the concrete slurry in the grouting barrel 1.

[0030] It should be noted that there are multiple crushing knife groups 4 and the second gear 62, and the number is the same. The multiple crushing knives 42 in the multiple crushing knife groups 4 are staggered with each other, so as to fully cover the cross-section inside the grouting barrel 1 and better crush the concrete slurry in the grouting barrel 1.

[0031] Among them, the outer wall of the protective shell 8 is fixed with a fixed rod 81 fixed to the caulking barrel 1, and the connecting part includes a fixed shaft 82. One end of the fixed shaft 82 is rotatably connected to the second gear 62 and the other end is fixed to the inner wall of the protective shell 8. The transmission shaft 7 movably passes through the protective shell 8 to fix the protective shell 8 on the inner wall of the caulking barrel 1 to prevent the protective shell 8 from moving.

[0032] Among them, a stirring blade 5 is fixed on the transmission shaft 7, and the stirring blade 5 is located between the crushing shaft 41 and the grouting pipe 11. Through the setting of the stirring blade 5, when the crushing knife 42 further crushes the aggregate in the concrete slurry, the transmission shaft 7 drives the stirring blade 5 to rotate to stir and mix the concrete slurry, so that the crushed aggregate is evenly distributed in the concrete slurry, making the grouting of the building gaps more uniform.

[0033] Among them, the end of the transmission shaft 7 close to the caulking tube 11 is rotatably connected to the support rod 9, the end of the support rod 9 away from the transmission shaft 7 is fixed to the inner wall of the caulking barrel 1, and the support rod 9 is located between the stirring blade 5 and the caulking tube 11. The support rod 9 provides stability for the transmission shaft 7 to ensure that the transmission shaft 7 will not deviate during rotation.

[0034] The working principle of the construction engineering structure gap grouting device of the present invention is as follows: during daily use, the staff only needs to turn on the motor 3 so that the motor 3 drives the feeding auger 2 to rotate through the transmission shaft 7. When the feeding auger 2 rotates, the grouting concrete slurry in the grouting barrel 1 is squeezed out from the grouting pipe 11 and the building gap is grouted; when the motor 3 drives the transmission shaft 7 to rotate, the transmission shaft 7 drives the crushing knife group 4 to rotate through the transmission assembly 6. Specifically, when the transmission shaft 7 rotates, it drives the first gear 61 to rotate, and when the first gear 61 rotates, it drives the second gear 62 to rotate, and the second gear The wheel 62 drives the crushing knife 42 to rotate through the crushing shaft 41, thereby using the power of the transmission shaft 7 to drive the crushing knife 42 to crush the concrete slurry in the grouting barrel 1, thereby crushing the larger aggregates contained in the concrete slurry in the grouting barrel 1, making the concrete slurry particles finer, more conducive to filling narrow gaps, and improving the quality of grouting; at the same time, the transmission shaft 7 drives the stirring blade 5 to rotate to stir and mix the concrete slurry, so that the crushed aggregates are evenly distributed in the concrete slurry, making the grouting of building gaps more uniform.

[0035] The present invention has substantial characteristics and significant technological progress. The construction engineering structure gap grouting device of the present invention is provided with a transmission component and a crushing knife group. When the motor drives the transmission shaft to rotate, the transmission shaft drives the crushing knife group to rotate through the transmission component, thereby crushing the larger aggregates contained in the concrete slurry in the grouting barrel, making the concrete slurry particles finer, which is more conducive to filling narrow gaps and improving the quality of grouting.

[0036] The above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Persons skilled in the art may make various modifications or variations without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions are intended to fall within the scope of the present invention and are defined by the claims.
