Description

Technical Field

[0001] The present invention relates to the technical field of concrete grouting, and particularly to a concrete grouting device for a steel reinforcement cage. Background Art

[0002] With the progress of engineering construction, the application of some precast concrete members of steel reinforcement cages is also increasing. The precast concrete member of steel reinforcement cage is a common precast concrete member, which is composed of a steel reinforcement cage and concrete. The steel reinforcement cage is a reticular structure formed by processing and welding high-strength steel bars according to the design requirements. During the manufacturing process, the steel reinforcement cage is first fabricated and placed in a prefabrication mold, and then concrete is poured into the mold so that the steel reinforcement cage is completely wrapped in the concrete. After the concrete centrifugally solidifies, the precast member is formed. The precast concrete member of steel reinforcement cage has good bearing capacity and seismic performance and is widely used in fields such as bridges, tunnels, subways, water conservancy projects, and building construction.

[0003] Currently, when the existing concrete grouting device grouts the steel reinforcement cage, it is inconvenient to control the flow rate of the grouting concrete. For some steel reinforcement cages of different sizes, when the grouting volume per unit time is large for a steel reinforcement cage with a small size and thin steel bars, it is easy to damage the steel reinforcement cage. However, when the grouting volume is large for a steel reinforcement cage with a large size and thick steel bars, the grouting volume per unit time is small, which will affect the concrete grouting speed of the steel reinforcement cage and the overall construction efficiency, and has poor adaptability and great limitations. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A concrete grouting device for a steel reinforcement cage, comprising: A grouting cylinder, and a servo motor installed at the side of the bottom of the grouting cylinder, wherein a mixing mechanism is installed at the side of the top of the grouting cylinder; An extrusion mechanism for pushing and grouting the concrete, and the extrusion mechanism is installed in the middle of the interior of the grouting cylinder; Among them, the material extrusion mechanism includes a rotating shaft and a blower. The outer circumferential surface of the rotating shaft is fixedly connected with a pushing blade, and the pushing blade is spiral. An air duct is opened at the middle of the rotating shaft, and an air spraying hole is opened at the middle of the pushing blade. One end of the rotating shaft extending outside the grouting cylinder is equipped with a rotating connector. An end of the grouting cylinder away from the servo motor is provided with a discharging assembly. By using the rotation of the output end of the servo motor and driven by the belt pulley assembly, the rotating shaft is driven to rotate, and the pushing blade will rotate with the rotating shaft. Combining with the spiral shape of the pushing blade, as the concrete material falls into the grouting cylinder, a driving force can be applied to the concrete material, and the concrete material can be pushed towards the discharging assembly, so as to continuously supply the concrete material and perform the concrete grouting of the steel reinforcement cage. The adjusting mechanism is used to control the concrete discharging amount and is installed at one end of the grouting cylinder surface away from the blower. Among them, the adjusting mechanism includes a conical blind hole and a plugging cover. The conical blind hole is opened at one end of the rotating shaft away from the rotating connector, and the plugging cover is fixedly installed at one end of the grouting cylinder surface away from the blower. The center of the plugging cover surface is fixedly connected with a driver. A bracket is rotatably installed at the middle of the plugging cover cavity. The top of the bracket is fixedly connected with a one-way plugging piece, the bottom of the bracket is fixedly connected with a two-way plugging piece, and a supporting cone is rotatably installed at the middle of the bracket surface. By using the plugging cover installed at the end of the grouting cylinder, the end of the grouting cylinder can be blocked, which is convenient for the concrete in the grouting cylinder to enter and gather at the position of the discharging assembly. And by using the tip of the supporting cone embedded into the conical blind hole and under the rotational support of the supporting cone, the end of the rotating shaft can be supported, so that the rotating shaft drives the pushing blade to rotate smoothly, further promoting the pushing of the concrete material in the grouting cylinder.

[0005] Preferably, the rotating shaft is rotatably installed at the middle of the grouting cylinder, the blower is fixedly installed at the side of the top of the grouting cylinder, the axis of the rotating shaft coincides with the axis of the grouting cylinder, and the output end of the servo motor is installed in transmission with the rotating shaft through a belt transmission assembly.

[0006] With the rotation of the rotating shaft and the rotational connection of the rotating connector, the rotation of the rotating shaft is smooth and it is not easy to have the situation of structural jamming. Using the blower as the power, by blowing air from the blower and through the connection of the U-shaped pipe, the gas enters the inside of the air duct and sprays out from the air spraying hole, reducing the adhesion of the concrete slurry on the edge of the pushing blade to the inner wall of the grouting cylinder, reducing the resistance, and making the pushing blade rotate smoothly, achieving an energy-saving effect.

[0007] Preferably, the air injection holes are evenly distributed in the middle of the inside of the pushing blade. The air injection holes are communicated with the air duct. The air outlet end of the fan is connected to the rotating connector through a U-shaped pipe, and the air duct is communicated with the bottom end of the U-shaped pipe.

[0008] Preferably, the discharging assembly includes a first rectangular opening and a second rectangular opening. The first rectangular opening is formed at the bottom of the inner cavity of the grouting cylinder, and the second rectangular opening is formed at the bottom of the inner cavity of the grouting cylinder. The first rectangular opening and the second rectangular opening are formed at the same height. The bottom of the grouting cylinder is fixedly connected with a first discharging cylinder, and the first discharging cylinder is installed directly below the first rectangular opening. The bottom of the grouting cylinder is fixedly connected with a second discharging cylinder, and the second discharging cylinder is installed directly below the second rectangular opening. Blades are fixedly connected to the inner walls of the first discharging cylinder and the second discharging cylinder. As the concrete material in the grouting cylinder is pushed by the pushing blade and gathers at the positions of the first rectangular opening and the second rectangular opening, the concrete material can enter the inside of the second discharging cylinder and the inside of the second discharging cylinder, so that the concrete material contacts the blades. The blades are used to divide the concrete material flowing in a stream, so that the concrete flowing downward for grouting is divided into smaller streams, destroying the cohesive structure of the cement paste, reducing the local viscous resistance, and promoting the outflow of the concrete material from the first rectangular opening and the second rectangular opening for grouting.

[0009] Preferably, the first discharging cylinder and the second discharging cylinder are both installed obliquely, and the blades are evenly distributed on the inner walls of the first discharging cylinder and the second discharging cylinder.

[0010] Preferably, the one-way blocking piece and the two-way blocking piece are symmetrically installed along the support cone, and the tip of the support cone faces the rotating shaft.

[0011] By using the two-way blocking piece at the bottom, the first rectangular opening and the second rectangular opening can be blocked, so that the concrete material in the grouting cylinder will not flow downward randomly. When it is necessary to control the discharge amount of the concrete material, the staff starts the driver to work. By using the rotation of the output end of the driver, the bracket can be driven to rotate, so that the one-way blocking piece and the two-way blocking piece will rotate together with the bracket. By using the one-way blocking piece at the bottom, one of the first rectangular opening and the second rectangular opening can be blocked, so that the concrete grouting amount per unit time can be reduced, thus adapting to the steel reinforcement cage with small size and thin steel bars, not easily damaging the steel reinforcement cage, and making full use of the interaction between structures to connect the structures together.

[0012] Preferably, the mixing mechanism includes a mixing bin and a power source. The mixing bin is installed at the top of the grouting cylinder, and the power source is fixedly installed at the side of the top of the mixing bin. A sleeve is rotatably installed at the middle of the top of the mixing bin, and a T-shaped rotating member is rotatably installed at the center of the sleeve. A clamping groove is formed at the edge of the top of the T-shaped rotating member. The output end of the power source is fixedly installed with a rotating gear disc. A bent tooth is fixedly connected to the bottom of the outer circumferential surface of the sleeve. The bottom end of the T-shaped rotating member is fixedly connected with a diamond-shaped frame. A feeding assembly is installed at the feeding port at the top of the mixing bin. A stress tooth is fixedly connected to the top of the outer circumferential surface of the sleeve. When the concrete enters the inside of the mixing bin and uses the power source as the power, the rotating gear disc can be driven to rotate. By combining that both the stress tooth and the clamping groove are meshed and installed with the rotating gear disc, the sleeve and the T-shaped rotating member are driven to rotate, and the rotating directions of the sleeve and the T-shaped rotating member are opposite. Then, the rotating directions of the bent tooth and the diamond-shaped frame are opposite, so that the concrete can be evenly stirred to promote the uniform mixing of the concrete. And by connecting the bottom of the mixing bin with the grouting cylinder, the concrete can be fed.

[0013] Preferably, the T-shaped rotating member passes through the center of the sleeve. The clamping grooves are evenly distributed at the edge of the top of the T-shaped rotating member. The bent tooth and the diamond-shaped frame are installed inside the mixing bin. The stress teeth are evenly distributed at the top of the outer circumferential surface of the sleeve.

[0014] Preferably, the feeding assembly includes a feeding hopper. The bottom end of the feeding hopper is fixedly installed at the side of the top of the mixing bin. A sector plate is rotatably installed at the top of the inner cavity of the mixing bin, and the sector plate is installed at the position of the discharge port of the feeding hopper. A reset elastic strip is fixedly connected between the surface of the sector plate and the top of the inner cavity of the mixing bin. When the concrete is put into the mixing bin from the feeding hopper, under the impact of the concrete fluid, the sector plate rotates counterclockwise to adjust the angle, which is convenient for the concrete to enter the inside of the mixing bin. And the reset elastic strip is compressed. By using the sector plate to block the feeding port of the feeding hopper, when the bent tooth and the diamond-shaped frame rotate to mix the concrete, it is not easy for the concrete material to fly out. And with the suspension of putting the concrete from the feeding hopper, and under the elastic force of the reset elastic strip, the sector plate rotates clockwise to reset, so that the sector plate can block the feeding port of the feeding hopper, thus preventing the concrete in the mixing bin from overflowing.

[0015] Preferably, the sector plate is inclined. The reset elastic strip is arc-shaped. There are two reset elastic strips, and the two reset elastic strips are symmetrically installed along the axis in the middle of the sector plate.

[0016] The present invention provides a concrete grouting device for a steel reinforcement cage, which has the following beneficial effects: 1. The concrete grouting device for the steel reinforcement cage utilizes the rotation of the output end of the servo motor. Driven by the pulley assembly, the rotating shaft is driven to rotate, and the pushing blades will rotate along with the rotating shaft. Since the pushing blades are spiral, as the concrete material drops into the grouting cylinder, a driving force can be applied to the concrete material, pushing the concrete material towards the discharging assembly, thereby continuously supplying the concrete material and enabling the concrete grouting of the steel reinforcement cage.

[0017] 2. The concrete grouting device for the steel reinforcement cage, with the rotation of the rotating shaft and under the rotational connection of the rotating connector, enables the rotating shaft to rotate smoothly without the risk of structural jamming. Using a blower as the power source, air is blown through the blower and enters the interior of the air duct through the connection of the U-shaped pipe, and then sprays out from the air holes, reducing the adhesion of the concrete slurry between the edge of the pushing blade and the inner wall of the grouting cylinder, reducing the resistance, and enabling the pushing blade to rotate smoothly, achieving an energy-saving effect.

[0018] 3. The concrete grouting device for the steel reinforcement cage utilizes a sealing cover installed at the end of the grouting cylinder to seal the end of the grouting cylinder, facilitating the aggregation of the concrete in the grouting cylinder at the position of the discharging assembly. Moreover, with the tip of the supporting cone embedded in the internal conical blind hole and under the rotational support of the supporting cone, the end of the rotating shaft can be supported, enabling the rotating shaft to drive the pushing blade to rotate smoothly, further promoting the pushing of the concrete material in the grouting cylinder.

[0019] 4. The concrete grouting device for the steel reinforcement cage, as the concrete material in the grouting cylinder is pushed by the pushing blade and aggregates at the positions of the first rectangular opening and the second rectangular opening, the concrete material can enter the interior of the second discharging cylinder and the interior of the second discharging cylinder, enabling the concrete material to contact the blades. The blades are used to divide the flowing concrete material in strands, dividing the downward-flowing grouting concrete into smaller flow streams, destroying the cohesive structure of the cement paste, reducing the local viscous resistance, and promoting the outflow of the concrete material from the first rectangular opening and the second rectangular opening for grouting.

[0020] 5. The concrete grouting device for the steel reinforcement cage utilizes a two-way sealing piece at the bottom to seal the first rectangular opening and the second rectangular opening, preventing the concrete material in the grouting cylinder from flowing downward randomly.

[0021] 6. The concrete grouting device for the steel reinforcement cage utilizes the rotation of the output end of the driver to drive the bracket to rotate, causing the one-way sealing piece and the two-way sealing piece to rotate along with the bracket. With the one-way sealing piece at the bottom, one of the first rectangular opening and the second rectangular opening can be sealed, reducing the amount of concrete grouting per unit time, thus being adaptable to steel reinforcement cages with small sizes and thin steel bars and not easily damaging the steel reinforcement cages.

[0022] VII. The concrete grouting device of the steel reinforcement cage uses a power source as the power, which can drive the rotating gear disc to rotate. By combining the force-bearing teeth and the card slots that are both meshed and installed with the rotating gear disc, the sleeve and the T-shaped rotating member are driven to rotate, and the rotating directions of the sleeve and the T-shaped rotating member are opposite. Thus, the bending teeth and the diamond-shaped frame can rotate in opposite directions, which can uniformly stir the concrete, promote the uniform mixing of the concrete, and connect the bottom of the mixing bin with the grouting cylinder to feed the concrete.

[0023] VIII. In the concrete grouting device of the steel reinforcement cage, under the impact of the concrete fluid, the fan-shaped plate rotates counterclockwise to adjust the angle, facilitating the entry of the concrete into the interior of the mixing bin. The reset elastic strip is compressed, and the fan-shaped plate is used to block the feeding port of the feeding hopper, so that when the bending teeth and the diamond-shaped frame rotate to mix the concrete, it is not easy for the concrete material to fly out. And with the suspension of the concrete feeding from the feeding hopper, under the elastic force of the reset elastic strip, the fan-shaped plate rotates clockwise to reset, so that the fan-shaped plate can block the feeding port of the feeding hopper, thus preventing the concrete in the mixing bin from overflowing.

[0027] The first embodiment is as Figures 1 to 5 shown. The present invention provides a technical solution: A concrete grouting device for a steel reinforcement cage, comprising: A grouting cylinder 1, and a servo motor 2 installed at the bottom side of the grouting cylinder 1, and a mixing mechanism 3 is installed at the top side of the grouting cylinder 1; A material extrusion mechanism 4, which is used to push and grout the concrete. The material extrusion mechanism 4 is installed in the middle of the interior of the grouting cylinder 1; Among them, the material extrusion mechanism 4 includes a rotating shaft 41 and a fan 42. The outer circumferential surface of the rotating shaft 41 is fixedly connected with a pushing blade 43, and the pushing blade 43 is spiral. An air duct 44 is opened in the middle of the rotating shaft 41, and an air injection hole 45 is opened in the middle of the pushing blade 43. One end of the rotating shaft 41 extending to the outside of the grouting cylinder 1 is installed with a rotating connector 46. A discharging component 47 is installed at the bottom end of the grouting cylinder 1 and on the side away from the servo motor 2. The staff starts the servo motor 2 to work, utilizes the rotation of the output end of the servo motor 2, and drives the rotating shaft 41 to rotate under the transmission of the belt pulley assembly. And the pushing blade 43 will rotate with the rotating shaft 41. Combining with the spiral shape of the pushing blade 43, as the concrete material drops into the grouting cylinder 1, a driving force can be applied to the concrete material to push the concrete material in the direction towards the discharging component 47; The rotating shaft 41 is rotatably installed at the middle inside the grouting cylinder 1, and the blower 42 is fixedly installed at the side of the top of the grouting cylinder 1. The axis of the rotating shaft 41 coincides with the axis of the grouting cylinder 1. The output end of the servo motor 2 is drivingly installed with the rotating shaft 41 through a belt pulley assembly.

[0028] With the rotation of the rotating shaft 41 and under the rotational connection of the rotary connector 46, the rotation of the rotating shaft 41 is smooth and it is not easy to have the situation of structural jamming. The staff starts the blower 42 to work. Using the blower 42 as the power, through the blowing of the blower 42, and under the connection of the U-shaped pipe, the gas enters the inside of the air duct 44 and sprays out from the air spray holes 45, reducing the adhesion of the concrete slurry between the edge of the pushing blade 43 and the inner wall of the grouting cylinder 1, reducing the resistance, and making the pushing blade 43 rotate smoothly.

[0029] The air spray holes 45 are evenly distributed at the middle inside the pushing blade 43. The air spray holes 45 are communicated with the air duct 44. The air outlet end of the blower 42 is connected with the rotary connector 46 through a U-shaped pipe, and the air duct 44 is communicated with the bottom end of the U-shaped pipe.

[0030] The discharging assembly 47 includes a first rectangular opening 471 and a second rectangular opening 472.

A second discharging cylinder 474 is fixedly connected to the bottom of the grouting cylinder 1, and the second discharging cylinder 474 is installed directly below the second rectangular opening 472. Blades 475 are fixedly connected to the inner walls of both the first discharging cylinder 473 and the second discharging cylinder 474. As the concrete material in the grouting cylinder 1 is pushed by the pushing blade 43 and gathers at the positions of the first rectangular opening 471 and the second rectangular opening 472, the concrete material can enter the inside of the second discharging cylinder 474 and the inside of the second discharging cylinder 474, making the concrete material contact the blades 475. The blades 475 are used to divide the concrete material flowing in a stream into smaller streamlets, destroying the cohesive structure of the cement paste, reducing the local viscous resistance, and promoting the flow of the concrete material out of the grouting through the first rectangular opening 471 and the second rectangular opening 472.

[0031] Both the first discharging cylinder 473 and the second discharging cylinder 474 are inclinedly installed, and the blades 475 are evenly distributed on the inner walls of both the first discharging cylinder 473 and the second discharging cylinder 474.

[0032] Second Embodiment, on the basis of the first embodiment, please refer to Figures 1 to 7 as shown: Adjusting mechanism 5, which is used to control the concrete discharge amount, is installed on the surface of the grouting cylinder 1 at the end far from the blower 42; Among them, the adjusting mechanism 5 includes a conical blind hole 51 and a plugging cover 52. The conical blind hole 51 is opened at one end of the rotating shaft 41 far from the rotating connector 46. The plugging cover 52 is fixedly installed on the surface of the grouting cylinder 1 at the end far from the blower 42. A driver 53 is fixedly connected to the center of the surface of the plugging cover 52. A support 54 is rotatably installed in the middle of the inner cavity of the plugging cover 52. A one-way plugging piece 55 is fixedly connected to the top of the support 54. A two-way plugging piece 56 is fixedly connected to the bottom of the support 54. A support cone 57 is rotatably installed in the middle of the surface of the support 54. By installing the plugging cover 52 at the end of the grouting cylinder 1, the end of the grouting cylinder 1 can be plugged, facilitating the concrete in the grouting cylinder 1 to enter and gather at the position of the discharging assembly 47. And by embedding the tip of the support cone 57 into the conical blind hole 51 and under the rotational support of the support cone 57, the end of the rotating shaft 41 can be supported, enabling the rotating shaft 41 to drive the pushing blade 43 to rotate smoothly, further promoting the pushing of the concrete material in the grouting cylinder 1.

[0033] The one-way plugging piece 55 and the two-way plugging piece 56 are symmetrically installed along the support cone 57. The tip of the support cone 57 faces the rotating shaft 41. By having the two-way plugging piece 56 at the bottom, the first rectangular opening 471 and the second rectangular opening 472 can be plugged, preventing the concrete material in the grouting cylinder 1 from flowing downward randomly. When it is necessary to control the discharge amount of the concrete material, the staff turns on the driver 53 to work. By the rotation of the output end of the driver 53, the support 54 can be driven to rotate, causing the one-way plugging piece 55 and the two-way plugging piece 56 to rotate together with the support 54. By having the one-way plugging piece 55 at the bottom, one of the first rectangular opening 471 and the second rectangular opening 472 can be plugged, reducing the concrete grouting amount per unit time.

[0034] The third embodiment, on the basis of the first and second embodiments, please refer to Figures 1 to 9 as shown: The mixing mechanism 3 includes a mixing bin 31 and a power source 32. The mixing bin 31 is installed on the top of the grouting cylinder 1, and the power source 32 is fixedly installed at the side of the top of the mixing bin 31. A sleeve 33 is rotatably installed at the middle of the top of the mixing bin 31, and a T-shaped rotating member 34 is rotatably installed at the center of the sleeve 33. A clamping groove 35 is formed at the edge of the top of the T-shaped rotating member 34. The output end of the power source 32 is fixedly installed with a rotating gear disk 36. A bent tooth 37 is fixedly connected to the bottom of the outer circumferential surface of the sleeve 33. The bottom end of the T-shaped rotating member 34 is fixedly connected with a diamond-shaped frame 38. A feeding assembly 39 is installed at the feeding port of the top of the mixing bin 31. A stress tooth 310 is fixedly connected to the top of the outer circumferential surface of the sleeve 33. When the concrete enters the inside of the mixing bin 31, the staff starts the power source 32 to work. Using the power source 32 as the power, the rotating gear disk 36 can be driven to rotate. Combined with the fact that both the stress tooth 310 and the clamping groove 35 are meshed and installed with the rotating gear disk 36, the sleeve 33 and the T-shaped rotating member 34 are driven to rotate, and the rotating directions of the sleeve 33 and the T-shaped rotating member 34 are opposite. Then the rotating directions of the bent tooth 37 and the diamond-shaped frame 38 are opposite, so that the concrete can be evenly stirred, promoting the uniform mixing of the concrete. And through the connection between the bottom of the mixing bin 31 and the grouting cylinder 1, the concrete can be fed.

[0035] The T-shaped rotating member 34 passes through the center of the sleeve 33. The clamping grooves 35 are evenly distributed at the edge of the top of the T-shaped rotating member 34. The bent tooth 37 and the diamond-shaped frame 38 are installed inside the mixing bin 31. The stress teeth 310 are evenly distributed at the top of the outer circumferential surface of the sleeve 33.

[0036] The feeding assembly 39 includes a feeding hopper 391. The bottom end of the feeding hopper 391 is fixedly installed at the side of the top of the mixing bin 31. A sector plate 392 is rotatably installed at the top of the inner cavity of the mixing bin 31, and the sector plate 392 is installed at the position of the discharge port of the feeding hopper 391. A reset elastic strip 393 is fixedly connected between the surface of the sector plate 392 and the top of the inner cavity of the mixing bin 31. When the concrete is put into the mixing bin 31 from the feeding hopper 391, under the impact of the concrete fluid, the sector plate 392 rotates counterclockwise to adjust the angle, facilitating the entry of the concrete into the inside of the mixing bin 31, and the reset elastic strip 393 is compressed. And the feeding port of the feeding hopper 391 is blocked by the sector plate 392, so that when the bent tooth 37 and the diamond-shaped frame 38 rotate to mix the concrete, it is not easy for the concrete material to fly out. And with the suspension of putting the concrete from the feeding hopper 391, and under the elastic force of the reset elastic strip 393, the sector plate 392 rotates clockwise to reset, so that the sector plate 392 can block the feeding port of the feeding hopper 391, thus preventing the concrete in the mixing bin 31 from overflowing.

[0037] The sector plate 392 is inclinedly installed. The reset elastic strip 393 is arc-shaped. There are two reset elastic strips 393, and the two reset elastic strips 393 are symmetrically installed along the axis in the middle of the sector plate 392.

[0038] During use, first install the plugging cover 52 at the end of the grouting cylinder 1, then the end of the grouting cylinder 1 can be plugged, which is convenient for the concrete in the grouting cylinder 1 to enter and gather at the position of the discharging component 47. And the tip of the supporting cone 57 is embedded into the internal conical blind hole 51, and under the rotational support of the supporting cone 57, the end of the rotating shaft 41 can be supported, so that the rotating shaft 41 drives the pushing blade 43 to rotate smoothly. Put the concrete from the feeding hopper 391. Under the impact of the concrete fluid, the sector plate 392 rotates counterclockwise to adjust the angle, which is convenient for the concrete to enter the inside of the mixing bin 31, and the reset elastic strip 393 is compressed. And the staff starts the power source 32 to work. Using the power source 32 as the power, the rotating gear disk 36 can be driven to rotate. Combined with the force-bearing tooth 310 and the clamping groove 35 are both meshed and installed with the rotating gear disk 36, the sleeve 33 and the T-shaped rotating part 34 are driven to rotate. And the rotating directions of the sleeve 33 and the T-shaped rotating part 34 are opposite, so that the bending teeth 37 and the diamond frame 38 rotate in opposite directions, and the concrete can be evenly stirred to promote the uniform mixing of the concrete. And through the connection between the bottom of the mixing bin 31 and the grouting cylinder 1, the concrete can be fed. And use the sector plate 392 to block the feeding port of the feeding hopper 391, so that when the bending teeth 37 and the diamond frame 38 rotate to mix the concrete, it is not easy for the concrete material to fly out. And with the suspension of putting the concrete from the feeding hopper 391, and under the elastic force of the reset elastic strip 393, the sector plate 392 rotates clockwise to reset, so that the sector plate 392 can block the feeding port of the feeding hopper 391, so that the concrete in the mixing bin 31 will not overflow. And the staff starts the servo motor 2 to work. Using the rotation of the output end of the servo motor 2, and under the transmission of the belt pulley assembly, the rotating shaft 41 is driven to rotate, and the pushing blade 43 will rotate together with the rotating shaft 41. Combined with the spiral shape of the pushing blade 43, as the concrete material falls into the grouting cylinder 1, a driving force can be applied to the concrete material to push the concrete material in the direction towards the discharging component 47. With the rotation of the rotating shaft 41 and under the rotational connection of the rotating connector 46, the rotation of the rotating shaft 41 is smooth and it is not easy to get stuck in the structure. The staff turns on the fan 42 to work. Using the fan 42 as the power, the fan 42 blows air. Under the connection of the U-shaped pipe, the gas enters the inside of the air duct 44 and sprays out from the air injection holes 45, reducing the adhesion of the concrete slurry on the inner wall of the grouting cylinder 1 at the edge of the pushing blade 43, reducing the resistance and making the pushing blade 43 rotate smoothly; Moreover, with the two-way blocking piece 56 at the bottom, the first rectangular opening 471 and the second rectangular opening 472 can be blocked, so that the concrete material in the grouting cylinder 1 will not flow down randomly. As the concrete material in the grouting cylinder 1 is pushed by the pushing blade 43 and gathers at the positions of the first rectangular opening 471 and the second rectangular opening 472, the output end of the driver 53 can drive the bracket 54 to rotate, making the two-way blocking piece 56 rotate away from the tops of the first rectangular opening 471 and the second rectangular opening 472, so that the concrete material can enter the inside of the second discharge cylinder 474 and the inside of the second discharge cylinder 474, making the concrete material contact the blade 475. The blade 475 is used to divide the concrete material flowing down in a stream, dividing the grouting concrete flowing downward into smaller streams, destroying the cohesive structure of the cement paste, reducing the local viscous resistance, and promoting the flow of the concrete material out of the first rectangular opening 471 and the second rectangular opening 472 for grouting; When it is necessary to control the discharge of the concrete material, the staff turns on the driver 53 to work. Using the rotation of the output end of the driver 53, the bracket 54 can be driven to rotate, so that the one-way blocking piece 55 and the two-way blocking piece 56 will rotate together with the bracket 54. With the one-way blocking piece 55 at the bottom, one of the first rectangular opening 471 and the second rectangular opening 472 can be blocked, reducing the amount of concrete grouting per unit time.
