Description
Technical Field
[0001] This invention relates to the field of concrete grouting technology, specifically to a concrete grouting device for a reinforcing cage. Background Technology
[0002] With the advancement of engineering construction, the application of precast reinforced concrete cages is becoming increasingly common. Precast reinforced concrete cages are a common type of precast concrete component, consisting of a reinforcing cage and concrete. The reinforcing cage is a mesh structure formed by processing and welding high-strength steel bars according to design requirements. During fabrication, the reinforcing cage is first processed and placed in a precast mold. Then, concrete is poured into the mold, completely encasing the reinforcing cage. After the concrete has solidified, the precast component is formed. Precast reinforced concrete cages possess good load-bearing capacity and seismic performance, and are widely used in bridges, tunnels, subways, water conservancy projects, and building construction.
[0003] Currently, existing concrete grouting devices are inconvenient to control the flow rate of grout when grouting steel cages. For steel cages of different sizes, a large grouting volume per unit time for smaller cages with thinner bars can easily damage the steel cage. On the other hand, for larger cages with thicker bars, a small grouting volume per unit time can affect the grouting speed of the steel cage, thus affecting the overall construction efficiency. This results in poor adaptability and significant limitations. Summary of the Invention
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A concrete grouting device for a reinforcing cage, comprising:
[0006] A grouting cylinder, and a servo motor installed at the bottom side of the grouting cylinder, and a mixing mechanism installed at the top side of the grouting cylinder;
[0007] The extrusion mechanism is used for pushing and grouting concrete, and the extrusion mechanism is installed in the middle of the grouting cylinder.
[0008] The extrusion mechanism includes a rotating shaft and a blower. A pusher blade is fixedly connected to the outer surface of the rotating shaft, and the pusher blade is spiral-shaped. An air passage is opened in the middle of the rotating shaft, and an air jet hole is opened in the middle of the pusher blade. A rotating connector is installed at one end of the rotating shaft extending to the outside of the grouting cylinder. A discharge component is installed at the bottom of the grouting cylinder on the side away from the servo motor. By rotating the output end of the servo motor and driving the pulley assembly, the rotating shaft is driven to rotate, and the pusher blade rotates with the rotating shaft. Since the pusher blade is spiral-shaped, as the concrete material falls into the grouting cylinder, a pushing force is applied to the concrete material, pushing the concrete material towards the discharge component, thereby continuously supplying concrete material for concrete grouting of the reinforcing cage.
[0009] An adjusting mechanism is used to control the concrete output. The adjusting mechanism is installed on the surface of the grouting cylinder and at one end away from the blower.
[0010] The adjusting mechanism includes a conical blind hole and a sealing cap. The conical blind hole is located at the end of the rotating shaft away from the rotating connector. The sealing cap is fixedly installed on the surface of the grouting cylinder and at the end away from the blower. A driver is fixedly connected to the center of the sealing cap surface. A bracket is rotatably installed in the middle of the inner cavity of the sealing cap. A one-way sealing plate is fixedly connected to the top of the bracket, and a two-way sealing plate is fixedly connected to the bottom of the bracket. A support cone is rotatably installed in the middle of the bracket surface. By installing the sealing cap at the end of the grouting cylinder, the end of the grouting cylinder can be sealed, facilitating the concrete in the grouting cylinder to enter and accumulate at the discharge component. The tip of the support cone is embedded in the conical blind hole, and under the rotational support of the support cone, the end of the rotating shaft can be supported, so that the rotating shaft drives the pusher blade to rotate smoothly, further promoting the pushing of concrete material in the grouting cylinder.
[0011] Preferably, the rotating shaft is rotatably installed in the middle of the grouting cylinder, the blower is fixedly installed on 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 connected to the rotating shaft through a belt drive assembly.
[0012] As the shaft rotates, and with the rotating connector in place, the shaft rotates smoothly, preventing structural jamming. A fan is used as power, blowing air through a U-shaped tube into the air duct and then ejecting it from the nozzle. This reduces the adhesion between the edge of the pusher blades and the concrete slurry on the inner wall of the grouting cylinder, thus reducing resistance and ensuring smooth rotation of the pusher blades, resulting in energy savings.
[0013] Preferably, the jet holes are evenly distributed in the middle of the inside of the pusher blades, the jet holes are connected to the air passage, the air outlet of the blower is connected to the rotary connector through a U-shaped tube, and the air passage is connected to the bottom end of the U-shaped tube.
[0014] Preferably, the discharge assembly includes a first rectangular opening and a second rectangular opening. The first rectangular opening is located at the bottom of the inner cavity of the grouting cylinder, and the second rectangular opening is located at the bottom of the inner cavity of the grouting cylinder, with the first and second rectangular openings at the same height. A first discharge cylinder is fixedly connected to the bottom of the grouting cylinder and is installed directly below the first rectangular opening. A second discharge cylinder is fixedly connected to the bottom of the grouting cylinder and is installed directly below the second rectangular opening. Blades are fixedly connected to the inner walls of both the first and second discharge cylinders. As the concrete material in the grouting cylinder is pushed and gathered at the positions of the first and second rectangular openings by the pushing blades, the concrete material can enter the interior of the second discharge cylinder and the interior of the second discharge cylinder, allowing the concrete material to contact the blades. The blades divide the downward-flowing concrete material into smaller streams, breaking the cohesive structure of the cement paste, reducing local viscous resistance, and promoting the flow of concrete material out of the first and second rectangular openings.
[0015] Preferably, both the first and second discharge cylinders are installed at an angle, and the blades are evenly distributed on the inner walls of the first and second discharge cylinders.
[0016] Preferably, the unidirectional and bidirectional sealing plates are symmetrically installed along the supporting cone, with the tip of the supporting cone facing the axis of rotation.
[0017] By using the bidirectional sealing plate at the bottom, the first and second rectangular openings can be sealed, preventing the concrete material inside the grouting cylinder from flowing downwards arbitrarily. When it is necessary to control the discharge rate of concrete material, the operator starts the driver. The rotation of the driver's output end causes the support to rotate, causing both the unidirectional and bidirectional sealing plates to rotate with the support. By using the unidirectional sealing plate at the bottom, one of the first or second rectangular openings can be sealed, thus reducing the amount of concrete grout injected per unit time. This makes it suitable for small-sized steel cages with thinner reinforcing bars, minimizing damage to the steel cage and fully utilizing the interaction between structures to connect them together.
[0018] Preferably, the mixing mechanism includes a mixing hopper and a power source. The mixing hopper is installed on top of the grouting cylinder, and the power source is fixedly installed on the side of the top of the mixing hopper. A sleeve is rotatably installed in the middle of the top of the mixing hopper, and a T-shaped rotating component is rotatably installed in the center of the sleeve. A groove is formed at the top edge of the T-shaped rotating component. A rotating gear is fixedly installed at the output end of the power source. A bent tooth is fixedly connected to the bottom of the outer surface of the sleeve. A diamond-shaped frame is fixedly connected to the bottom end of the T-shaped rotating component. An upper... The material assembly has a force-bearing tooth fixedly connected to the top of the outer circular surface of the sleeve. The concrete enters the interior of the mixing hopper. Using a power source, the rotating toothed disc is driven to rotate. The force-bearing tooth and the slot are engaged with the rotating toothed disc, causing the sleeve and the T-shaped rotating component to rotate. The sleeve and the T-shaped rotating component rotate in opposite directions, which makes the bending tooth and the diamond frame rotate in opposite directions, so as to evenly stir the concrete and promote uniform mixing. The bottom of the mixing hopper is connected to the grouting cylinder, so the concrete can be fed in.
[0019] Preferably, the T-shaped rotating member passes through the center of the sleeve, the slots are evenly distributed on the top edge of the T-shaped rotating member, the bending teeth and the rhomboid frame are installed inside the mixing bin, and the force-bearing teeth are evenly distributed on the top of the outer surface of the sleeve.
[0020] Preferably, the feeding assembly includes a feeding hopper, the bottom of which is fixedly installed at the side of the top of the mixing silo. A sector plate is rotatably installed on the top of the inner cavity of the mixing silo, and the sector plate is installed at 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 silo. When concrete is fed into the mixing silo from the feeding hopper, the impact of the concrete fluid causes the sector plate to rotate counterclockwise to adjust its angle, facilitating the entry of concrete into the mixing silo. The reset elastic strip is compressed, and the sector plate blocks the inlet of the feeding hopper, preventing concrete material from flying out when the bending teeth and diamond frame rotate to mix the concrete. When the feeding of concrete from the feeding hopper is stopped, the sector plate rotates clockwise to reset under the elastic force of the reset elastic strip, thus sealing the inlet of the feeding hopper and preventing concrete from overflowing from the mixing silo.
[0021] Preferably, the sector plate is installed at an angle, the reset elastic strip is arc-shaped, there are two reset elastic strips, and the two reset elastic strips are installed symmetrically along the axis at the middle of the sector plate.
[0022] This invention provides a concrete grouting device for reinforcing cages. It has the following beneficial effects:
[0023] 1. The concrete grouting device for the reinforcing cage utilizes the rotation of the output end of the servo motor, which, under the transmission of the pulley assembly, drives the rotating shaft to rotate. The pusher blades rotate together with the rotating shaft, and since the pusher blades are spiral-shaped, as the concrete material falls into the grouting cylinder, a pushing force is applied to the concrete material, pushing it towards the discharge assembly, thereby continuously supplying concrete material for concrete grouting of the reinforcing cage.
[0024] Second, the concrete grouting device for the reinforcing cage, with the rotation of the shaft and the rotation connection of the rotating connector, makes the shaft rotate smoothly and is less prone to structural jamming. Using a fan as power, the fan blows air, and with the connection of the U-shaped pipe, the air enters the interior of the air passage and is sprayed out from the air jet hole. This reduces the adhesion between the edge of the pusher blade and the concrete grout on the inner wall of the grouting cylinder, thereby reducing resistance and making the pusher blade rotate smoothly, thus achieving an energy-saving effect.
[0025] Third, the concrete grouting device of the reinforcing cage uses a sealing cap installed at the end of the grouting cylinder to seal the end of the grouting cylinder, which facilitates the concrete in the grouting cylinder to enter and gather at the discharge component. The tip of the supporting cone is embedded in the conical blind hole, and the end of the rotating shaft is supported by the rotation of the supporting cone, so that the rotating shaft drives the pushing blade to rotate smoothly, further promoting the pushing of concrete material in the grouting cylinder.
[0026] IV. The concrete grouting device for the reinforcing cage, as the concrete material in the grouting cylinder is pushed and gathered at the positions of the first rectangular opening and the second rectangular opening by the pusher blades, allows the concrete material to enter the interior of the second discharge cylinder and the second discharge cylinder, so that the concrete material comes into contact with the blades. The blades divide the concrete material flowing downwards, so that the downward flowing grouting concrete is divided into smaller streams, which destroys the cohesive structure of the cement paste, reduces local viscous resistance, and promotes the concrete material to flow out of the first rectangular opening and the second rectangular opening for grouting.
[0027] 5. The concrete grouting device of the steel cage uses a two-way sealing plate at the bottom to seal the first and second rectangular openings, so that the concrete material in the grouting cylinder will not flow downwards at will.
[0028] VI. The concrete grouting device for the reinforcing cage utilizes the rotation of the output end of the driver to drive the support to rotate, causing the one-way sealing plate and the two-way sealing plate to rotate together with the support. By using the one-way sealing plate at the bottom, one of the first rectangular opening and the second rectangular opening can be sealed, thereby reducing the amount of concrete grouting per unit time. This makes it suitable for reinforcing cages with small size and thinner reinforcing bars, and it is less likely to damage the reinforcing cage.
[0029] VII. The concrete grouting device for the reinforcing cage uses a power source to drive the rotating gear disc to rotate. The force-bearing teeth and the slots are engaged with the rotating gear disc, causing the sleeve and the T-shaped rotating part to rotate. The sleeve and the T-shaped rotating part rotate in opposite directions, which makes the bending teeth and the diamond frame rotate in opposite directions, so as to evenly stir the concrete and promote uniform mixing. The device is connected to the bottom of the mixing hopper and the grouting cylinder, so as to feed the concrete.
[0030] 8. The concrete grouting device of the reinforcing cage, under the impact of the concrete fluid, causes the sector plate to rotate counterclockwise to adjust the angle, facilitating the entry of concrete into the mixing hopper. The reset elastic strip is compressed, and the sector plate blocks the feed inlet of the hopper, making it less likely for concrete material to fly out when the bending teeth and diamond frame rotate to mix the concrete. When concrete is stopped from being fed from the feed hopper, the sector plate rotates clockwise to reset under the elastic force of the reset elastic strip, thus blocking the feed inlet of the feed hopper and preventing the concrete in the mixing hopper from overflowing.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.
[0042] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution:
[0043] A concrete grouting device for a reinforcing cage, comprising:
[0044] Grouting cylinder 1, and servo motor 2 installed at the bottom side of grouting cylinder 1, and mixing mechanism 3 installed at the top side of grouting cylinder 1;
[0045] The extrusion mechanism 4 is used for pushing and grouting concrete. The extrusion mechanism 4 is installed in the middle of the grouting cylinder 1.
[0046] The extrusion mechanism 4 includes a rotating shaft 41 and a blower 42. A pusher blade 43 is fixedly connected to the outer surface of the rotating shaft 41. The pusher blade 43 is spiral in shape. An air passage 44 is opened in the middle of the rotating shaft 41. An air jet hole 45 is opened in the middle of the pusher blade 43. A rotating connector 46 is installed at one end of the rotating shaft 41 that extends to the outside of the grouting cylinder 1. A discharge component 47 is installed at the bottom of the grouting cylinder 1 on the side away from the servo motor 2. When the operator starts the servo motor 2, the rotating shaft 41 is driven to rotate by the rotation of the output end of the servo motor 2 and the drive of the pulley assembly. The pusher blade 43 rotates with the rotating shaft 41. Since the pusher blade 43 is spiral in shape, as the concrete material falls into the grouting cylinder 1, a pushing force is applied to the concrete material, pushing the concrete material toward the discharge component 47.
[0047] The rotating shaft 41 is rotatably installed in the middle of the grouting cylinder 1, and the blower 42 is fixedly installed on 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, and the output end of the servo motor 2 is installed with the rotating shaft 41 through a pulley assembly.
[0048] As the shaft 41 rotates, and with the rotating connection of the rotating connector 46, the shaft 41 rotates smoothly, making it less prone to structural jamming. The operator turns on the blower 42 to work, using the blower 42 as power to blow air, and with the connection of the U-shaped pipe, the air enters the interior of the air passage 44 and is sprayed out from the jet hole 45, reducing the adhesion between the edge of the pusher blade 43 and the concrete slurry on the inner wall of the grouting cylinder 1, thus reducing resistance and allowing the pusher blade 43 to rotate smoothly.
[0049] The jet holes 45 are evenly distributed in the middle of the inside of the pusher blades 43. The jet holes 45 are connected to the air passage 44. The air outlet of the blower 42 is connected to the rotary connector 46 through a U-shaped tube. The air passage 44 is connected to the bottom end of the U-shaped tube.
[0050] The discharge assembly 47 includes a first rectangular opening 471 and a second rectangular opening 472. The first rectangular opening 471 is located at the bottom of the inner cavity of the grouting cylinder 1, and the second rectangular opening 472 is located at the bottom of the inner cavity of the grouting cylinder 1. The first rectangular opening 471 and the second rectangular opening 472 are located at the same height. A first discharge cylinder 473 is fixedly connected to the bottom of the grouting cylinder 1 and is installed directly below the first rectangular opening 471. A second discharge cylinder 474 is fixedly connected to the bottom of the grouting cylinder 1 and is installed directly below the second rectangular opening 472. The inner wall of the first discharge cylinder 473 and the second discharge cylinder 474 are connected together. Blades 475 are fixedly connected to the inner wall. As the concrete material in the grouting cylinder 1 is pushed and gathered at the positions of the first rectangular opening 471 and the second rectangular opening 472 by the pusher blades 43, the concrete material can enter the interior of the second discharge cylinder 474 and the interior of the second discharge cylinder 474, so that the concrete material comes into contact with the blades 475. The blades 475 are used to divide the concrete material flowing downwards, so that the downward flowing grouting concrete is divided into smaller streams, which destroys the cohesive structure of the cement paste, reduces local viscous resistance, and promotes the concrete material to flow out of the first rectangular opening 471 and the second rectangular opening 472 for grouting.
[0051] The first discharge cylinder 473 and the second discharge cylinder 474 are both installed at an angle, and the blades 475 are evenly distributed on the inner walls of the first discharge cylinder 473 and the second discharge cylinder 474.
[0052] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown:
[0053] Adjustment mechanism 5 is used to control the concrete discharge amount. Adjustment mechanism 5 is installed on the surface of grouting cylinder 1 and at one end away from blower 42.
[0054] The adjusting mechanism 5 includes a conical blind hole 51 and a sealing cover 52. The conical blind hole 51 is located at the end of the rotating shaft 41 away from the rotating connector 46. The sealing cover 52 is fixedly installed on the surface of the grouting cylinder 1 at the end away from the blower 42. A driver 53 is fixedly connected to the center of the surface of the sealing cover 52. A bracket 54 is rotatably installed in the middle of the inner cavity of the sealing cover 52. A one-way sealing plate 55 is fixedly connected to the top of the bracket 54, and a two-way sealing plate 56 is fixedly connected to the bottom of the bracket 54. A supporting cone 57 is rotatably installed at the end of the grouting cylinder 1. The end of the grouting cylinder 1 is sealed by the sealing cap 52, which facilitates the concrete in the grouting cylinder 1 to enter and gather at the discharge component 47. The tip of the supporting cone 57 is embedded in the conical blind hole 51. With the rotational support of the supporting cone 57, the end of the rotating shaft 41 is supported, so that the rotating shaft 41 drives the pusher blade 43 to rotate smoothly, further promoting the pushing of concrete material in the grouting cylinder 1.
[0055] One-way sealing plate 55 and two-way sealing plate 56 are symmetrically installed along the supporting cone 57, with the tip of the supporting cone 57 facing the rotating shaft 41. By using the two-way sealing plate 56 at the bottom, the first rectangular opening 471 and the second rectangular opening 472 can be sealed, so that the concrete material in the grouting cylinder 1 will not flow downward randomly. When it is necessary to control the discharge of concrete material, the operator starts the driver 53. By using the rotation of the output end of the driver 53, the bracket 54 can be rotated, so that the one-way sealing plate 55 and the two-way sealing plate 56 will rotate together with the bracket 54. By using the one-way sealing plate 55 at the bottom, one of the first rectangular opening 471 and the second rectangular opening 472 can be sealed, thereby reducing the amount of concrete grouting per unit time.
[0056] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 1 to 9 As shown:
[0057] The mixing mechanism 3 includes a mixing bin 31 and a power source 32. The mixing bin 31 is installed on top of the grouting cylinder 1. The power source 32 is fixedly installed on the side of the top of the mixing bin 31. A sleeve 33 is rotatably installed in the middle of the top of the mixing bin 31. A T-shaped rotating part 34 is rotatably installed in the center of the sleeve 33. A slot 35 is opened at the top edge of the T-shaped rotating part 34. A rotating gear 36 is fixedly installed at the output end of the power source 32. A bent tooth 37 is fixedly connected to the bottom of the outer surface of the sleeve 33. A diamond frame 38 is fixedly connected to the bottom end of the T-shaped rotating part 34. A feeding assembly 39 is installed at the feed inlet at the top of the mixing bin 31. The top of the outer surface of the sleeve 33 is fixedly... The concrete enters the mixing silo 31 through the fixed connection of the force-bearing teeth 310. The operator turns on the power source 32 to start working. Using the power source 32 as power, the rotating toothed disc 36 is driven to rotate. The force-bearing teeth 310 and the slot 35 are engaged with the rotating toothed disc 36, so that the sleeve 33 and the T-shaped rotating part 34 are driven to rotate. The sleeve 33 and the T-shaped rotating part 34 rotate in opposite directions, so that the bending teeth 37 and the diamond frame 38 rotate in opposite directions, which can evenly stir the concrete and promote uniform mixing. The concrete is then connected to the grouting cylinder 1 through the bottom of the mixing silo 31, so that the concrete can be fed.
[0058] The T-shaped rotating part 34 passes through the center of the sleeve 33, the slots 35 are evenly distributed on the top edge of the T-shaped rotating part 34, the bending teeth 37 and the rhomboid frame 38 are installed inside the mixing bin 31, and the force-bearing teeth 310 are evenly distributed on the top of the outer surface of the sleeve 33.
[0059] The feeding assembly 39 includes a feeding hopper 391. A side panel of the top of a mixing silo 31 is fixedly installed at the bottom of the feeding hopper 391. A sector plate 392 is rotatably mounted on the top of the inner cavity of the mixing silo 31, and the sector plate 392 is installed at 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 silo 31. Concrete is fed into the mixing silo 31 from the feeding hopper 391. Under the impact of the concrete fluid, the sector plate 392 rotates counterclockwise to adjust its angle, facilitating the entry of concrete into the mixing silo 31. Inside the mixing hopper 31, the reset elastic strip 393 is compressed, and the fan-shaped plate 392 blocks the feed inlet of the hopper 391, so that when the bent teeth 37 and the diamond frame 38 rotate to mix the concrete, it is not easy for concrete material to fly out. When the concrete is stopped from being fed from the hopper 391, the fan-shaped plate 392 rotates clockwise to reset under the elastic force of the reset elastic strip 393, so that the fan-shaped plate 392 can block the feed inlet of the hopper 391, thus preventing the concrete in the mixing hopper 31 from overflowing.
[0060] The sector plate 392 is installed at an angle, and the reset elastic strip 393 is arc-shaped. There are two reset elastic strips 393, and the two reset elastic strips 393 are installed symmetrically along the axis at the middle of the sector plate 392.
[0061] In use, the sealing cap 52 is first installed at the end of the grouting cylinder 1 to seal the end of the grouting cylinder 1, so that the concrete in the grouting cylinder 1 can enter and gather at the position of the discharge component 47. The tip of the supporting cone 57 is embedded in the inside of the conical blind hole 51, and the end of the rotating shaft 41 is supported by the rotation of the supporting cone 57, so that the rotating shaft 41 drives the pusher blade 43 to rotate smoothly.
[0062] Concrete is fed from the hopper 391. Under the impact of the concrete fluid, the sector plate 392 rotates counterclockwise to adjust the angle, so that the concrete can enter the interior of the mixing hopper 31, and the reset elastic strip 393 is compressed.
[0063] The staff turns on the power source 32 to work. Using the power source 32 as power, the rotating toothed disc 36 is driven to rotate. The force-bearing teeth 310 and the slot 35 are engaged with the rotating toothed disc 36, so that the sleeve 33 and the T-shaped rotating part 34 are driven to rotate. The sleeve 33 and the T-shaped rotating part 34 rotate in opposite directions, so that the bending teeth 37 and the diamond frame 38 rotate in opposite directions, which can evenly stir the concrete and promote the uniform mixing of the concrete. The concrete can be fed into the grouting cylinder 1 through the bottom of the mixing hopper 31.
[0064] The fan-shaped plate 392 is used to block the feed inlet of the hopper 391, so that when the bent tooth 37 and the diamond frame 38 rotate to mix the concrete, it is not easy for concrete material to fly out. When the concrete is stopped from being fed from the hopper 391, the fan-shaped plate 392 rotates clockwise to reset under the elastic force of the reset elastic strip 393, so that the fan-shaped plate 392 can block the feed inlet of the hopper 391, thus preventing the concrete in the mixing bin 31 from overflowing.
[0065] The staff then starts the servo motor 2 to work. The rotation of the output end of the servo motor 2, and the drive of the pulley assembly, causes the rotating shaft 41 to rotate. The pusher blade 43 rotates with the rotating shaft 41. Since the pusher blade 43 is spiral, as the concrete material falls into the grouting cylinder 1, a pushing force can be applied to the concrete material, pushing it towards the discharge component 47.
[0066] As the rotating shaft 41 rotates, and with the rotating connection of the rotating connector 46, the rotating shaft 41 rotates smoothly, making it less likely for the structure to jam. The staff turns on the blower 42 to work, using the blower 42 as power, blowing air through the blower 42, and with the connection of the U-shaped pipe, the air enters the interior of the air passage 44 and is sprayed out from the jet hole 45, reducing the adhesion between the edge of the pusher blade 43 and the concrete slurry on the inner wall of the grouting cylinder 1, thus reducing resistance and allowing the pusher blade 43 to rotate smoothly.
[0067] Furthermore, by using the bidirectional sealing plate 56 at the bottom, the first rectangular opening 471 and the second rectangular opening 472 can be sealed, preventing the concrete material in the grouting cylinder 1 from flowing downwards at will. As the concrete material in the grouting cylinder 1 is pushed and gathered at the positions of the first rectangular opening 471 and the second rectangular opening 472 by the pusher blade 43, the output end of the driver 53 can drive the bracket 54 to rotate, causing the bidirectional sealing plate 56 to rotate and move away from the top of the first rectangular opening 471 and the second rectangular opening 472, allowing the concrete material to enter the interior of the second discharge cylinder 474 and the interior of the second discharge cylinder 474, so that the concrete material comes into contact with the blade 475. The blade 475 is used to divide the downward-flowing concrete material, dividing the downward-flowing grouting concrete into smaller streams, destroying the cohesive structure of the cement paste, reducing local viscous resistance, and promoting the concrete material to flow out of the first rectangular opening 471 and the second rectangular opening 472 for grouting.
[0068] When it is necessary to control the discharge of concrete materials, the operator turns on the driver 53. The rotation of the output end of the driver 53 can drive the bracket 54 to rotate, so that the one-way sealing plate 55 and the two-way sealing plate 56 will rotate together with the bracket 54. With the one-way sealing plate 55 at the bottom, one of the first rectangular opening 471 and the second rectangular opening 472 can be blocked, thereby reducing the amount of concrete grouting per unit time.
