[0002] Anti-crack mortar is a special mortar used on the surface of buildings. Its main function is to resist surface cracking. It is made by mixing its components with water in a certain proportion. It can adapt to the deformation of the structure to a certain extent without cracking. It becomes stronger with the increase of water, so it is suitable for occasions that require a certain toughness. In addition, anti-crack mortar also has the properties of easy construction and anti-freeze, which makes it widely used in the construction industry.

[0003] Existing anti-cracking mortars usually use polymers as binders, and then add additives such as glass fiber mesh or steel wire mesh as additives to enhance the strength and crack resistance of the mortar. This means that in the process of laying the mortar, it is necessary to first lay the glass fiber mesh or steel wire mesh, and then lay the mixed mortar. The steps are cumbersome, inconvenient to process, and affect the construction efficiency. In addition, when using steel wire mesh as an admixture, the steel wire will rust during long-term use, which will affect the anti-cracking performance of the building. For this reason, an aramid fiber anti-cracking mortar protective structure is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in the present embodiment, an aramid fiber anti-cracking mortar protection structure comprises a mixing drum 1, a mixing mechanism is arranged inside the mixing drum 1, a feeding mechanism is arranged above the mixing drum 1, the feeding mechanism consists of a mounting frame 6, a No. 1 conveying member 9 and a No. 2 conveying member 10, a supporting foot 7 is arranged at the bottom of the mounting frame 6, a No. 1 shell 2 and a No. 2 shell 3 are fixedly installed above the mounting frame 6, a No. 1 shell 2 and a No. 2 shell 3 are rotatably installed inside the No. 1 shell 2 and the No. 2 shell 3 respectively, a plurality of material storage troughs 11 distributed in a circular array are opened on the outer walls of the No. 1 conveying member 9 and the No. 2 conveying member 10, a driving mechanism is connected between the No. 1 conveying member 9 and the No. 2 conveying member 10, the No. 1 shell 2 and the No. 2 shell 3 have the same structure, and the No. 1 conveying member 9 and the No. 2 conveying member 10 have the same structure.

[0021] Among them, the driving mechanism is composed of a No. 1 motor 8, a No. 1 gear 12, a No. 2 gear 13, a rotating shaft 14, a No. 3 gear 15, and a No. 4 gear 16. The No. 1 motor 8 is fixedly connected to the outer wall of one end of the No. 1 housing 2, and the No. 1 gear 12 is rotatably connected to the outer wall of the other end of the No. 1 housing 2. The No. 1 gear 12 is fixedly connected to the No. 1 conveying member 9, the No. 2 gear 13 is meshed with the No. 1 gear 12, and the diameters of the No. 2 gear 13 and the No. 1 gear 12 are equal. One end of the No. 2 gear 13 is rotatably connected to the No. 1 housing 2, the other end of the No. 2 gear 13 is fixedly connected to the rotating shaft 14, and the other end of the rotating shaft 14 is rotatably connected to the outer wall of the No. 2 housing 3, and the No. 3 gear 15 is fixedly connected to the outer wall of the rotating shaft 14, the No. 4 gear 16 is meshed with the No. 3 gear 15, the No. 4 gear 16 is rotatably connected to the outer wall of the No. 2 housing 3, and the No. 4 gear 16 is fixedly connected to the No. 2 conveying member 10.

[0022] When in use, start the No. 1 motor 8 to drive the No. 1 conveying member 9 to rotate, thereby driving the No. 1 gear 12 to rotate, the No. 1 gear 12 will drive the No. 2 gear 13 to rotate, and under the action of the rotating shaft 14, the No. 3 gear 15 will rotate synchronously, and the No. 3 gear 15 will drive the No. 4 gear 16 to rotate, thereby driving the No. 2 conveying member 10 to rotate. Since the diameters of the No. 1 gear 12 and the No. 2 gear 13 are equal, the No. 2 gear 13 and the No. 3 gear 15 are coaxial, the rotation speeds of the No. 1 gear 12, the No. 2 gear 13 and the No. 3 gear 15 are equal, so the ratio of the diameters of the No. 3 gear 15 and the No. 4 gear 16 is equal to the rotation speed ratio of the No. 2 conveying member 10 and the No. 1 conveying member 9.

[0023] Among them, the stirring mechanism is composed of a fixed plate 19, a No. 2 motor 20 and a stirring member 17. The fixed plate 19 is fixedly connected to the upper opening position of the stirring drum 1. The No. 2 motor 20 is fixedly connected to the upper end of the fixed plate 19. The stirring member 17 is rotatably connected to the bottom of the fixed plate 19. The output shaft of the No. 2 motor 20 is fixedly connected to the upper end of the stirring member 17.

[0024] The stirring member 17 is driven to rotate by the second motor 20, so that the anti-cracking mortar and the aramid 1313 fiber are mixed and stirred.

[0025] Among them, the upper ends of the No. 1 shell 2 and the No. 2 shell 3 are both provided with a storage bin 4 connected to the interior thereof, and the bottoms of the No. 1 shell 2 and the No. 2 shell 3 are both provided with a material guide port 5 connected to the interior thereof, and the bottom of the material guide port 5 is located above the opening of the mixing drum 1.

[0026] The two storage bins 4 can respectively store the anti-cracking mortar and the aramid 1313 fiber, and the material guide port 5 can guide the anti-cracking mortar and the aramid 1313 fiber to the mixing drum 1.

[0027] A material receiving pipe 18 is provided at the bottom side of the mixing drum 1 , and a valve is provided on the material receiving pipe 18 .

[0028] The material receiving pipe 18 can be provided to facilitate the staff to receive the materials.

[0029] The utility model provides an aramid fiber anti-crack mortar protection structure, and the specific working principle is as follows:

[0030] The two storage bins 4 are respectively used to store aramid fiber 1313 and anti-cracking mortar. The aramid fiber 1313 and anti-cracking mortar will flow into the storage troughs 11 on the No. 1 conveyor 9 and the No. 2 conveyor 10 respectively. The No. 1 conveyor 9 and the No. 2 conveyor 10 are driven to rotate by the driving mechanism. The multiple storage troughs 11 on the No. 1 conveyor 9 and the No. 2 conveyor 10 will make circular motion, so that the aramid fiber 1313 and anti-cracking mortar are evenly delivered to the guide port 5, and are delivered into the mixing drum 1 along the guide port 5. Since the diameters of the No. 1 gear 12 and the No. 2 gear 13 are equal, the No. 2 gear 13 and the No. 3 gear 15 are coaxial, and the rotation speeds of the No. 1 gear 12, the No. 2 gear 13 and the No. 3 gear 15 are equal, the diameter ratio between the No. 3 gear 15 and the No. 4 gear 16 is equal to the rotation speed ratio between the No. 2 conveyor 10 and the No. 1 conveyor 9. By controlling the rotational speed ratio between the No. 1 conveyor 9 and the No. 2 conveyor 10, the feeding ratio of the aramid 1313 fiber and the anti-cracking mortar can be controlled, and then the aramid 1313 fiber and the anti-cracking mortar are stirred by a stirring mechanism, so that the proportional aramid 1313 fiber and the anti-cracking mortar can be quickly mixed together to obtain a new anti-cracking mortar with protective measures. Since the strength and crack resistance of aramid 1313 fiber are much better than those of glass fiber and steel mesh, adding aramid 1313 fiber to the mortar can effectively enhance the anti-cracking effect of the building surface. When laying the mortar, the glass fiber mesh or steel mesh in the prior art can be removed, reducing the processing steps and improving the construction efficiency.

[0031] 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.
