[0051] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0052] This utility model provides an improved surface defect repair device for cement products. The technical solution of this utility model is as follows:

[0053] like Figures 1-6 As shown, a surface defect repair device for cement products includes:

[0054] Housing 1, with a round hole on one side;

[0055] Turntable 2, which is rotatably set inside the circular hole;

[0056] The rotating shaft 6 is fixed to the turntable 2, and the rotating shaft 6 is rotatably connected to the housing 1;

[0057] Multiple repair components are set on turntable 2;

[0058] The pneumatic assembly is connected to the rotating shaft 6, and the pneumatic assembly is also connected to multiple repair assemblies;

[0059] Motor 5 is fixed on the side wall of housing 1, and the output shaft and rotating shaft 6 of motor 5 are also present.

[0060] Furthermore, the repair components include:

[0061] Two through holes 3 are provided on the side wall of the turntable 2, and a slider 23 is slidably installed in each through hole 3.

[0062] Furthermore, it also includes:

[0063] Scraper 24, scraper 24 is fixed on one of the sliders 23;

[0064] Brush plate 25, brush plate 25 is fixed on another slider 23.

[0065] Furthermore, the repair components also include:

[0066] Two connecting brackets 17 are fixed to the side wall of the turntable 2;

[0067] Two second sleeves 18 are fixed to two connecting brackets 17 respectively;

[0068] Two second pistons 19 are slidably connected to two second sleeves 18 respectively;

[0069] Two second sleeve rods 22 are fixed to two second pistons 19 respectively, and two second sleeve rods 22 are fixed to two sliders 23 respectively.

[0070] The air pressure in the first annular tube 13 and the second annular tube 14 acts on the second piston 19 under the action of the second tube body 21, thereby adjusting the state of the second sleeve rod 22.

[0071] Furthermore, it also includes:

[0072] Two springs 20 are fixed to the inner walls of the two second sleeves 18 respectively, and the two springs 20 are fixed to the nearest second piston 19 respectively;

[0073] Two second tubes 21 are connected to two second sleeves 18 respectively.

[0074] The spring 20 can reset the second piston 19 when the device is not in operation, so that both the scraper 24 and the brush plate 25 are in the through hole 3.

[0075] Furthermore, the pneumatic components include:

[0076] Support plate 7 is fixed to rotating shaft 6;

[0077] Connecting shaft 9 is slidably connected to support plate 7, and counterweights 10 are fixed at both ends of connecting shaft 9.

[0078] Connecting plates 8, two connecting plates 8 are respectively fixed to the two ends of the connecting shaft 9.

[0079] Furthermore, it also includes:

[0080] The first annular tube 13 and the second annular tube 14 are both disposed inside the housing 1, and the two second tubes 21 are respectively connected to the first annular tube 13 and the second annular tube 14.

[0081] Two air supply units are fixed to two connecting plates 8 respectively, and the two air supply units are connected to the first annular pipe 13 and the second annular pipe 14 respectively.

[0082] Furthermore, the gas supply unit includes:

[0083] The first sleeve 11 is fixed on the connecting plate 8;

[0084] The first piston 15 is slidably disposed within the first sleeve 11;

[0085] The first sleeve rod 12 is fixed to the first piston 15, and the first sleeve rod 12 is also fixed to the support plate 7;

[0086] The first tube body 16 is connected to the first sleeve 11.

[0087] Furthermore, one of the first tubes 16 is connected to the first annular tube 13, and the other first tube 16 is connected to the second annular tube 14.

[0088] During the rotation of the shaft 6, the action of the two counterweights 10 causes one connecting plate 8 to move away from the support plate 7, while the other connecting plate 8 moves closer to the support plate 7. This causes one of the first pistons 15 and the first sleeve rod 12 to retract into the first sleeve 11, while the other first piston 15 and the first sleeve rod 12 slide out of the first sleeve 11. Through the action of the first piston 15 and its cooperation with the first tube 16 on the first sleeve 11, the first annular tube 13 and the second annular tube 14 are respectively in a positive pressure and a negative pressure state.

[0089] When the rotation direction of the rotating shaft 6 is changed, the air pressure state in the first annular tube 13 and the second annular tube 14 can be changed under the action of inertia.

[0090] Furthermore, two handles 4 are fixed to the side wall of housing 1.

[0091] Handle 4 makes it easy for staff to hold the equipment.

[0092] Specifically, the working principle is as follows: During use, the motor 5 drives the rotating shaft 6 to rotate forward. During this process, the two counterweights 10 cause one connecting plate 8 to move away from the support plate 7, while the other connecting plate 8 moves closer to the support plate 7. This causes one of the first pistons 15 and the first sleeve rod 12 to retract into the first sleeve 11, while the other first piston 15 and the first sleeve rod 12 slide out of the first sleeve 11. Through the action of the first piston 15 and its cooperation with the first tube 16 on the first sleeve 11, the first annular tube 13 and the second annular tube 14 are respectively in a positive pressure and a negative pressure state.

[0093] The second tube 21 causes the air pressure in the second sleeve 18, which is connected to the first annular tube 13, to rise, thereby pushing the second piston 19 to move. This causes the corresponding second sleeve rod 22 and slider 23 to slide out of the through hole 3, and then the brush plate 25 to slide out of the through hole 3. At this time, in conjunction with the rotation of the turntable 2 and the brush plate 25, the surface of the cement product can be polished to remove the floating dust from the surface of the cement product.

[0094] Repair mortar is then applied to the surface of the cement product;

[0095] Next, the motor 5 drives the rotating shaft 6 to reverse. During the reverse rotation of the rotating shaft 6, the air pressure in the first annular tube 13 and the second annular tube 14 also changes, causing the brush plate 25 to slide into the through hole 3 and the scraper 24 to slide out of the through hole 3. With the rotation of the turntable 2, the scraper 24 can be used to smooth the repair mortar on the surface of the cement product.
