DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 3As shown, a concrete pile repair spraying device described in an embodiment of the utility model comprises a base 8; a hopper 81 is fixedly connected to the top of the base 8; a hose 82 is fixedly connected to the side wall of the hopper 81; a spray head 83 is fixedly connected to the end of the hose 82; two support frames 1 are fixedly connected to the top of the hopper 81; the two support frames 1 are arranged oppositely; motors 11 are fixedly connected to the ends of the two support frames 1; a stirring shaft 12 is fixedly connected to the output end of the motor 11; a stirring blade 13 is fixedly connected to the middle of the stirring shaft 12; an elastic cloth 14 is fixedly connected to the middle of the hopper 81 ; The elastic cloth 14 is fixed to the inside of the hopper 81; the side wall of the hopper 81 is fixed to multiple groups of elastic plates 15; the elastic plates 15 are arranged in an arc shape; the elastic plates 15 are fixed between the hopper 81 and the elastic cloth 14; a first magnetic block 16 is fixed to the middle of the elastic plate 15; a support rod 17 is fixed to the middle of the stirring blade 13; a second magnetic block 18 is fixed to the end of the support rod 17; the second magnetic block 18 and the first magnetic block 16 are attracted when they are close to each other. When working, concrete is placed in the hopper 81, and the concrete passes through the spray head 8 from the inside of the hose 82. 3, the motor 11 is powered on and turned on, so that the output end of the motor 11 rotates the stirring shaft 12, and the stirring blade 13 stirs in the concrete during the rotation of the stirring shaft 12. The first magnetic block 16 and the second magnetic block 18 are flexible magnets. When the stirring blade 13 rotates, the second magnetic block 18 and the first magnetic block 16 are close to each other and attract each other. When the second magnetic block 18 rotates away from the first magnetic block 16, they are instantly separated. When the second magnetic block 18 moves away from the first magnetic block 16, the elastic plate 15 rebounds due to its own elasticity. At this time, the elastic plate 15 hits the elastic cloth 1 The elastic cloth 14 is vibrated, and the stirring blades 13 can effectively reduce the uniform texture of the concrete during spraying, effectively reduce the problem of caking during concrete spraying, effectively reduce the poor fluidity caused by caking during concrete spraying, and effectively increase the mutual fusion and reaction effect of various components in the concrete, and the elastic plate 15 can effectively reduce the adhesion of concrete to the surface of the elastic cloth 14 during spraying, and effectively reduce the problem of waste caused by concrete remaining on the surface of the elastic cloth 14, thereby effectively reducing the cost of concrete spraying.

[0024] like Figure 3As shown, the side wall of the elastic plate 15 is fixed with multiple groups of springs 2; the ends of multiple groups of springs 2 are fixed to the elastic cloth 14; the side wall of the elastic plate 15 is fixed with multiple groups of elastic rods 21. During operation, when concrete is being mixed, the impact of concrete on the elastic cloth 14 is absorbed by the springs 2 and the elastic rods 21. The springs 2 and the elastic rods 21 can effectively reduce the vibration and impact of concrete on the surface of the elastic cloth 14 during mixing, increase the tension and deformation capacity of the elastic cloth 14, increase the pressure change when concrete flows, effectively reduce concrete residue, and adapt to the fluidity and viscosity of different types of concrete, effectively improving the quality and efficiency of concrete spraying.

[0025] like Figure 1 and Figure 3 As shown, the side wall of the hopper 81 is fixedly connected to a water pump 3; the middle part of the water pump 3 is fixedly connected to a water outlet pipe 31; the water outlet pipe 31 is arranged inside the hopper 81; the water outlet pipe 31 is fixedly connected to the hopper 81 near the top; a plurality of groups of water outlet holes 32 are provided in the middle part of the water outlet pipe 31; the plurality of groups of water outlet holes 32 are evenly distributed in the middle part of the water outlet pipe 31. During operation, when the concrete spraying is completed, the water pump 3 is turned on and connected to a water source, and water flows into the inside of the water outlet pipe 31 through the water pump 3, and the water flows are discharged to the surface of the elastic cloth 14 through the plurality of groups of water outlet holes 32. The concrete residue can be effectively washed by the water flow, and the concrete can be removed in time, which effectively reduces the accumulation of concrete residue on the surface of the elastic plate 15 and causes hardening. Reducing the concrete residue can effectively reduce the difficulty of cleaning caused by gradual hardening, and can effectively reduce the damage of the concrete residue to the surface of the elastic plate 15, and effectively reduce the pollution caused by the concrete residue inside the hopper 81.

[0026] like Figure 1 and Figure 4 As shown, the side wall of the hopper 81 is fixedly connected to a fixed rod 4; the bottom of the fixed rod 4 is fixedly connected to a telescopic rod 41; the end of the telescopic rod 41 is fixedly connected to a rotating shaft 42; the middle of the rotating shaft 42 is fixedly connected to a connecting rod 43; the end of the connecting rod 43 is fixedly connected to the middle of the spray head 83. During operation, when spraying concrete, the telescopic rod 41 is stretched and adjusted to a specified height, and then the spray head 83 is moved to make the connecting rod 43 rotate in the middle of the rotating shaft 42 to adjust the angle of the spray head 83. By adjusting the height and angle of the spray head 83, the concrete can be evenly and accurately attached to the target surface, effectively reducing the problem of uneven concrete spraying, and can be sprayed in different construction scenes and pile surfaces, and the height and angle of the concrete can be effectively and flexibly adjusted, which can effectively reduce invalid movement and repeated work during the spraying process, thereby improving the concrete spraying efficiency.

[0027] like Figure 1 and Figure 4As shown, the side wall of the spray head 83 is fixedly connected with multiple groups of hinge shafts 5; a baffle 51 is fixedly connected with the middle of the hinge shaft 5; the baffle 51 is arranged in an arc shape. During operation, concrete is sprayed out from the end of the spray head 83 by high pressure. When the concrete is sprayed out, it impacts the baffle 51. The baffle 51 subjected to the impact force rotates through the hinge shaft 5. A torsion spring is arranged between the hinge shaft 5 and the baffle 51. When the baffle 51 is not impacted, it is reset by the torsion spring. The multiple groups of baffles 51 can effectively reduce the impact of concrete during spraying, so that the concrete can be evenly attached to the target surface, effectively reducing the problem of unevenness or uneven coating of the concrete assembly due to the impact of high pressure, and can effectively reduce the damage to the target surface caused by the strong impact force, effectively improve the smoothness and overall quality of the spraying, and reduce the damage to the structure or material during spraying.

[0028] like Figure 3 As shown, a filter screen 6 is installed in the middle of the water outlet hole 32; the filter screen 6 is fixedly connected to the middle of the water outlet hole 32. During operation, when concrete is stirred inside the hopper 81, the filter screen 6 blocks the concrete from passing through the water outlet hole 32 and entering the water outlet pipe 31. The filter screen 6 can effectively reduce the splashing of concrete during the stirring process, effectively reduce the blockage caused by the splashing of concrete into the water outlet pipe 31, and effectively reduce the wear and scratches of the inner wall of the water outlet pipe 31 caused by the concrete entering the water outlet pipe 31, effectively increase the smoothness of the water flow, and effectively extend the service life of the water outlet pipe 31, thereby reducing the cost of maintenance and replacement.

[0029] like Figure 1 As shown, a soundproof cover 7 is installed on the side wall of the hopper 81; the soundproof cover 7 is fixedly connected to the side wall of the hopper 81. During operation, when spraying is performed, noise is generated during the mixing of concrete inside the hopper 81. The soundproof cover 7 absorbs part of the noise generated during the mixing. The soundproof cover 7 can effectively reduce the noise generated during operation, effectively increase the comfort of the working environment, reduce noise interference during work, and reducing noise can effectively increase the stability of the equipment, reduce the vibration caused by the noise, and effectively increase the service life of the equipment.

[0030] During operation, concrete is placed inside the hopper 81, and the concrete is sprayed out from the inside of the hose 82 through the spray head 83. The motor 11 is powered on and turned on, so that the output end of the motor 11 rotates the stirring shaft 12. When the stirring shaft 12 rotates, the stirring blade 13 stirs the concrete. The first magnetic block 16 and the second magnetic block 18 are flexible magnets. When the stirring blade 13 rotates, the second magnetic block 18 and the first magnetic block 16 are close to each other and attract each other. When the second magnetic block 18 rotates away from the first magnetic block 16, they are instantly separated. The elastic plate 15 rebounds when the second magnetic block 18 moves away from the first magnetic block 16 through its own elasticity. At this time, the elastic plate 15 hits the elastic cloth 14 to vibrate the elastic cloth 14. When the concrete is being stirred, the impact of the concrete on the elastic cloth 14 is absorbed by the spring 2 and the elastic rod 21. When the concrete spraying is completed, the water pump 3 is turned on and connected to the water source. Water flows into the outlet pipe 31 through the water pump 3, and the water flows out to the surface of the elastic cloth 14 through the multiple groups of outlet holes 32. When spraying concrete, the telescopic rod 41 is stretched and adjusted to a specified height, and then the spray head 83 is moved to rotate the connecting rod 43 in the middle of the rotating shaft 42 to adjust the angle of the spray head 83. Concrete is sprayed out from the end of the spray head 83 by high pressure. When the concrete is sprayed out, it impacts the baffle 51. The baffle 51 subjected to the impact force rotates through the hinge shaft 5. A torsion spring is provided between the hinge shaft 5 and the baffle 51. When the baffle 51 is not impacted, it is reset by the torsion spring. When the concrete is stirred inside the hopper 81, the filter screen 6 blocks the concrete from entering the outlet pipe 31 through the outlet holes 32. When spraying, the concrete generates noise during the stirring process inside the hopper 81, and part of the noise generated during the stirring is absorbed by the sound insulation cover 7.
