[0003] The existing eccentric vibrating rod can only agitate a small range of concrete around the hollow sleeve, the action range is small, and the air in the concrete is difficult to discharge due to the small gap between the concrete and the resistance of the compacted concrete, which affects the setting efficiency of the concrete and the air bubble discharge efficiency in the concrete.

[0008] Preferably, one end of the extension pipe is close to the eccentric rod, and the other end is inserted into the concrete outside, for intermittent receiving extrusion of the eccentric rod, and stirring the surrounding concrete.

[0009] Preferably, the extension pipe is inclined, and one end of the extension pipe close to the eccentric rod is at the high position of the inclination, and the other end is at the low position of the inclination, for expanding the stirring range and guiding the flow direction of the gas flow.

[0010] Preferably, the outer side of the bottom of the probe sleeve is provided with an annular sealing platform, the outer side of the vibrating rod is provided with an isolation sleeve, the top of the isolation sleeve is provided with a gas delivery hose, and the bottom of the isolation sleeve is threadedly connected with the outer side of the sealing platform, for providing a relatively sealed space to avoid a large amount of concrete from flowing in.

[0016] Meanwhile, the eccentric rod intermittently extrudes the extension pipes on the vibrating sleeve through the eccentric rotation, so that the extension pipes move farther away, and when the eccentric rod moves away from the extension pipes, the stretched elastic layer pulls the extension pipes to move back, so that the extension pipes not only synchronously swing with the vibrating sleeve, but also independently change the position intermittently, so that the extension pipes efficiently and multi-directionally stir the concrete around, and the processing efficiency is improved.

[0017] Meanwhile, by adding the isolation sleeve outside the vibrating sleeve, when the extension pipe stirs the concrete, most of the gas in the concrete can enter the air flow cavity of the extension pipe through the guide hole, and then enter the flow cavity between the isolation sleeve and the vibrating sleeve again, and finally be discharged from the gas conveying hose, so that the discharge efficiency of the gas in the concrete is improved.

DETAILED DESCRIPTION

[0029] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] Embodiment one

[0031] Please refer to Figures 1 to 3 A concrete pouring device for water conservancy projects comprises a power supply motor, a connecting hose 1, a vibrating rod, a vibrating sleeve 2, a probe sleeve 3, a soft spring 4, a connecting head 5, a soft shaft joint 6, a bearing 8, and an eccentric rod 7. The connecting hose 1 is connected in a way that does not affect the multi-directional swinging of the vibrating rod. The bottom of the connecting hose 1 is threadedly sleeved with the vibrating rod. The vibrating rod comprises the vibrating sleeve 2 threadedly connected to the bottom of the connecting hose 1 and the probe sleeve 3 threadedly sleeved to the bottom of the vibrating sleeve 2. The vibrating rod is used to seal the internal cavity of the vibrating rod, provide a space for the movement of the eccentric rod 7, avoid the entry of concrete into the vibrating rod, and enable the vibrating rod to extrude the surrounding concrete during swinging to complete the vibrating.

[0032] Please refer to Figure 3 , Figure 5 The inner cavity of the vibrating rod is movably sleeved with the eccentric rod 7. The top end of the eccentric rod 7 is fixedly connected with the soft shaft joint 6. The top of the soft shaft joint 6 is threadedly sleeved with the connecting head 5. The top end of the connecting head 5 is welded with the soft spring 4. The end of the soft spring 4 away from the connecting head 5 is fixedly connected with the output end of the motor. The outer side of the soft shaft joint 6 is movably sleeved with the bearing 8. When the motor is started, the rotating motion can be transmitted to the connecting head 5 through the soft spring 4, and then to the soft shaft joint 6, so that the soft shaft joint 6 can drive the eccentric rod 7 to rotate. Since the eccentric rod 7 is in an eccentric state, the eccentric rod 7 swings under the action of centrifugal force, thereby driving the entire vibrating rod to swing and performing the vibrating action on the surrounding concrete.

[0033] Please refer to Figures 1 to 4The side wall of the vibrating rod is provided with uniformly distributed movable holes 21, and the movable holes 21 are fixedly sleeved with elastic rubber layers 11, so that the elastic rubber layers 11 seal the movable holes 21 and provide restoring power for the extension pipes 12. The elastic rubber layers 11 are fixedly sleeved with the extension pipes 12, one end of the extension pipes 12 is close to the eccentric rod 7, and the other end is inserted into the concrete outside, so that the eccentric rotation of the eccentric rod 7 intermittently extrudes the end close to the extension pipe 12, and the extension pipe 12 moves to a farther place. At this time, the extension pipe 12 will pull the deformed and stretched elastic rubber layer 11, so that the extension pipe 12 moves to a farther place. When the eccentric rod 7 moves away from the extension pipe 12, the stretched elastic rubber layer 11 will pull the extension pipe to restore the movement, so that the extension pipe 12 not only swings synchronously with the vibrating sleeve pipe 2, but also changes the position intermittently, so as to efficiently and multi-directionally stir the concrete around the extension pipe 12, improve the processing efficiency, and the extension pipe 12 is inclined, the end of the extension pipe 12 close to the eccentric rod 7 is at an inclined high position, and the other end is at an inclined low position. When the extension pipe 12 swings synchronously with the vibrating sleeve pipe 2, due to the inclined design, the angle change of the position change of the extension pipe 12 is larger and the range is wider, the stirring effect of the surrounding concrete is stronger, the surrounding concrete is broken, and the surrounding gas is inclined to flow upward, improving the flow speed of the gas in the concrete.

[0034] Example two

[0035] Please refer to Figures 1 to 4 On the basis of example one, the outer bottom of the probe sleeve pipe 3 is welded with an annular sealing platform 31, the outer side of the vibrating rod is fixedly sleeved with an isolation sleeve pipe 10, the top of the isolation sleeve pipe 10 is threadedly sleeved with a gas conveying hose 9, the bottom of the isolation sleeve pipe 10 is threadedly connected with the outer side of the sealing platform 31, and the isolation sleeve pipe 10 and the vibrating rod form a flow cavity for gas flow. The extension pipe 12 penetrates through the isolation sleeve pipe 10, so that the isolation sleeve pipe 10 can guide the gas flow into the gas conveying hose 9, quickly discharge the concrete, and the isolation sleeve pipe 10 can be disassembled, facilitating replacement and cleaning.

[0036] Please refer to Figures 6 to 7 The extension pipe 12 includes a solid rod I 13, a hollow pipe 14 and a solid rod II 15, the two ends of the hollow pipe 14 are threadedly sleeved with the opposite ends of the solid rod I 13 and the solid rod II 15 respectively, so that the extension pipe 12 can be disassembled, facilitating replacement and cleaning, and the solid rod I 13 is fixedly sleeved in the elastic rubber layer 11, so that the gas entering the hollow pipe 14 is blocked by the solid rod I 13 and cannot enter the vibrating rod.

[0037] Please refer to Figure 7Hollow tube 14 is provided with air flow cavity 16, and evenly distributed guide holes 17 are provided on hollow tube 14. Air flow cavity 16 is connected with the outside through guide holes 17. When extending tube 12 agitates concrete, most of the gas in the concrete can enter air flow cavity 16 of extending tube 12 through guide holes 17, and then enter flow cavity between isolation sleeve 10 and vibrating sleeve 2 from guide holes 17, and finally be discharged from air delivery hose 9, thereby improving the discharge efficiency of gas in concrete.
