[0031] Furthermore, the inner wall of the infusion bin 5 is provided with a plurality of slurry outlets 7 which are evenly arranged in a circular array. The upper end of the core 4 is fixedly connected with a slurry delivery port 6 , and the interior of the slurry delivery port 6 is communicated with the infusion bin 5 .
[0032] For further information, see Figure 1 and Figure 3 The automatic knocking device includes a first rotating shaft 9, which is rotatably connected to the rear edge of the base 1. Both ends of the first rotating shaft 9 rotate through the outer surface of the base 1. The lower end fixed sleeve of the first rotating shaft 9 is provided with a first sprocket 20, and the upper end fixed sleeve of the first rotating shaft 9 is provided with a snail cam 10. Two first fixed plates 11 are fixedly connected to the upper surface of the base 1, and the two bases 1 are respectively located on both sides of the first rotating shaft 9.
[0033] Furthermore, a fixed shaft 12 is fixedly connected between the two first fixed plates 11, a rotating ring 13 is sleeved on the middle end of the fixed shaft 12, a torsion spring 17 is arranged between the rotating ring 13 and the fixed shaft 12, a first fixed rod 14 is fixedly connected to the outer surface of the rotating ring 13, the first fixed rod 14 is in contact with the outer contour of the snail cam 10, and a knocking rod 15 is fixedly connected to the outer surface of the rotating ring 13.
[0034] Furthermore, a knocking ball head 16 is fixedly connected to one end of the knocking rod 15 away from the rotating ring 13, a large sprocket 19 is fixedly sleeved on the lower end of the central axis 2, a chain 24 is transmission-connected between the first sprocket 20 and the large sprocket 19, a motor 23 is fixedly connected to the bottom plate of the base 1, and the output shaft of the motor 23 is fixedly inserted into the central axis 2.
[0035] Furthermore, when in use, the steel bar skeleton of the cement pipe is placed in the mold cavity 22, and the motor 23 is started. The output shaft of the motor 23 drives the central shaft 2 thereon to rotate. When the central shaft 2 rotates, the large sprocket 19 is driven to rotate. When the large sprocket 19 rotates, the core 4 thereon and the double-open casting mold 3 on the bottom cover 18 are driven to rotate. At this time, the gantry fixing frame 8 is slid so that the output end of the cement mixing and infusion equipment on the gantry fixing frame 8 is aligned with the slurry delivery port 6, and then the cement mixing and infusion equipment is started. The cement mixing and infusion equipment can squeeze the cement into the slurry delivery port 6, and the cement in the slurry delivery port 6 continues to enter the infusion bin 5. The cement will be penetrated by the centrifugal force when the core 4 rotates. The cement passes through the slurry outlet 7 and enters the cavity 22. The cement entering the cavity 22 will be thrown outward by the centrifugal force when the core 4 rotates. The cement passes through the steel skeleton and is evenly thrown onto the inner wall of the double-open casting mold 3. Then, under the action of the cement's own gravity, it slides into the bottom of the cavity 22 along the inner wall of the double-open casting mold 3 and the steel skeleton until the steel skeleton is completely wrapped. During the operation of the above structure, the cement will be thrown onto the inner wall of the double-open casting mold 3 by the centrifugal force, which can make the produced cement pipe structure very uniform, the outer surface of the cement pipe is smoother and the quality is higher, and there will be no large hollow areas, thereby improving the efficiency and quality of cement pipe production.
[0036] Furthermore, at this time, the rotating large sprocket 19 will drive the first sprocket 20 to rotate through the chain 24. When the first sprocket 20 rotates, it will drive the first rotating shaft 9 to rotate. When the first rotating shaft 9 rotates, it will drive the snail cam 10 at its upper end to rotate. When the snail cam 10 rotates, the first fixed rod 14 located at the minimum radius of the snail cam 10 will be affected by the gradually increasing radius of the outer surface contour when the snail cam 10 rotates, causing counterclockwise rotation. When the first fixed rod 14 rotates counterclockwise with the axis of the rotating ring 13, the torsion spring 17 thereon will be torsional deformation. The rotating rotating ring 13 will also drive the knocking ball head 16 on the knocking rod 15 to gradually move away from the outer surface of the double-open casting mold 3 until the snail cam 10 rotates to the end at the maximum radius and fits with the first fixed rod 14. Then the first fixed rod 14 will be held by the torsion spring 17 The continued clockwise rotation force falls into the smallest radius of the snail cam 10. At this time, the knocking ball head 16 will be hit hard on the outer surface of the double-open casting mold 3 by the clockwise rotation force of the rotating ring 13. The double-open casting mold 3 will vibrate when it is subjected to the impact force. The continuously rotating snail cam 10 will continuously drive the knocking ball head 16 to hit the outer surface of the rotating double-open casting mold 3, thereby vibrating out the residual bubbles and gaps in the cement in various places in the cavity 22, thereby effectively improving the surface quality of the cement pipe after production, avoiding the problem of too many bubbles in the produced cement pipe affecting the surface quality and structural strength. After molding, the gantry fixing frame 8 is slid to one side, the double-open casting mold 3 is manually opened and removed, and then the molded cement product is removed, and the next step can be carried out.
[0037] Working principle: When in use, the steel bar skeleton of the cement pipe is placed into the mold cavity 22, and the motor 23 is started. The output shaft of the motor 23 drives the central shaft 2 thereon to rotate. When the central shaft 2 rotates, it drives the large sprocket 19 to rotate. When the large sprocket 19 rotates, it drives the core 4 thereon and the double-open casting mold 3 on the bottom cover 18 to rotate. At this time, the gantry fixing frame 8 is slid so that the output end of the cement mixing and infusion equipment on the gantry fixing frame 8 is aligned with the slurry delivery port 6, and then the cement mixing and infusion equipment is started. The cement mixing and infusion equipment can squeeze the cement into the slurry delivery port 6, and the cement in the slurry delivery port 6 continues to enter the infusion bin 5. The cement will be penetrated by the centrifugal force of the core 4 when it rotates. The cement passes through the slurry outlet 7 and enters the cavity 22. The cement entering the cavity 22 will be thrown outward by the centrifugal force when the core 4 rotates. The cement passes through the steel skeleton and is evenly thrown onto the inner wall of the double-open casting mold 3. Then, under the action of the cement's own gravity, it slides into the bottom of the cavity 22 along the inner wall of the double-open casting mold 3 and the steel skeleton until the steel skeleton is completely wrapped. During the operation of the above structure, the cement will be thrown onto the inner wall of the double-open casting mold 3 by the centrifugal force, which can make the produced cement pipe structure very uniform, the outer surface of the cement pipe is smoother and the quality is higher, and there will be no large hollow areas, thereby improving the efficiency and quality of cement pipe production.
[0038] Furthermore, at this time, the rotating large sprocket 19 will drive the first sprocket 20 to rotate through the chain 24. When the first sprocket 20 rotates, it will drive the first rotating shaft 9 to rotate. When the first rotating shaft 9 rotates, it will drive the snail cam 10 at its upper end to rotate. When the snail cam 10 rotates, the first fixed rod 14 located at the minimum radius of the snail cam 10 will be affected by the gradually increasing radius of the outer surface contour when the snail cam 10 rotates, causing counterclockwise rotation. When the first fixed rod 14 rotates counterclockwise with the axis of the rotating ring 13, the torsion spring 17 thereon will be torsional deformation. The rotating rotating ring 13 will also drive the knocking ball head 16 on the knocking rod 15 to gradually move away from the outer surface of the double-open casting mold 3 until the snail cam 10 rotates to the end at the maximum radius and fits with the first fixed rod 14. Then the first fixed rod 14 will be held by the torsion spring 17 The continued clockwise rotation force falls into the smallest radius of the snail cam 10. At this time, the knocking ball head 16 will be hit hard on the outer surface of the double-open casting mold 3 by the clockwise rotation force of the rotating ring 13. The double-open casting mold 3 will vibrate when it is subjected to the impact force. The continuously rotating snail cam 10 will continuously drive the knocking ball head 16 to hit the outer surface of the rotating double-open casting mold 3, thereby vibrating out the residual bubbles and gaps in the cement in various places in the cavity 22, thereby effectively improving the surface quality of the cement pipe after production, avoiding the problem of too many bubbles in the produced cement pipe affecting the surface quality and structural strength. After molding, the gantry fixing frame 8 is slid to one side, the double-open casting mold 3 is manually opened and removed, and then the molded cement product is removed to proceed to the next step.
