[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figures 1 to 6 As shown in the embodiment of this utility model, a concrete vibration air bubble elimination device includes a push box 1, an installation box 2 fixedly installed on one side of the push box 1, a transmission component 3 fixedly installed on the installation box 2, four sets of lifting and shock-absorbing components 4 with identical structures are provided in the transmission component 3, and the four sets of lifting and shock-absorbing components 4 pass through the push box 1. The bottom end of each lifting and shock-absorbing component 4 is fixedly connected to a universal wheel 5. Two sets of brackets 14 are fixedly installed on one side of the push box 1, and adjustable scraper angle components 15 are fixedly installed on the two sets of brackets 14 respectively.

[0030] A servo motor 2 6 is fixedly installed on one side of the push box 1, and the output end of the servo motor 2 6 passes through the push box 1. A lead screw 7 is fixedly connected to one end of the servo motor 2 6. A slot is opened in the push box 1, and the lead screw 7 is located in the slot opened in the push box 1. A slider 8 is threadedly connected to the outside of the lead screw 7. An installation box 2 9 is fixedly installed in the slider 8. A motor 3 12 is fixedly installed on one side of the installation box 2 9. A rotating shaft 3 13 is fixedly connected to the output end of the motor 3 12, and the rotating shaft 3 13 is rotatably connected in the installation box 2 9 through a fixing plate 2 17. A vibrating assembly 1 10 and a vibrating assembly 2 11 are fixedly installed on the outside of the rotating shaft 3 13, and the vibrating assembly 1 10 is located on one side of the vibrating assembly 2 11.

[0031] Specifically, the operator can push the push rod with anti-slip texture on one side of the push box 1 to drive the caster 5 to move it, making it easy to move the entire device on the concrete construction surface. The bottom of the lifting and shock absorption assembly 4 is fixedly connected to the caster 5. On the one hand, the caster 5 allows the device to turn flexibly, making it easy to adjust its position and direction on the construction site, improving the flexibility of construction. On the other hand, the lifting and shock absorption assembly 4 can be adjusted according to the height of the construction ground to adapt to various complex construction environments, ensuring that vibration and leveling operations can be carried out at the appropriate height. At the same time, it plays a shock absorption role during movement and operation, ensuring the stable operation of the device. The servo motor 6 drives the lead screw 7 to rotate, causing the threaded connection on the outside of the lead screw 7 to slide. Block 8 moves horizontally, and slider 8 drives vibrating assembly 10 and vibrating assembly 21 to move horizontally within a certain range, expanding the vibration range and improving vibration efficiency. Vibrating assembly 10 and vibrating assembly 21 provide high-frequency and low-frequency vibration respectively through motor 3 12. High-frequency vibration can quickly remove air bubbles on the surface and in the shallow layer of concrete, making the internal structure of concrete more compact. Low-frequency vibration can penetrate into the deep layer of concrete, assisting in the removal of deep air bubbles, so that concrete fills every corner of the formwork. The two work together to greatly improve the vibration quality and uniformity of concrete. The adjustable scraper angle assembly 15 is installed on the bracket 14, which can scrape the concrete surface after the vibration operation is completed.

[0032] like Figures 2 to 3 As shown, the transmission component 3 includes a cylinder 31 fixedly installed on the upper surface of the mounting box 2, and the output shaft of the cylinder 31 passes through the mounting box 2. The output shaft of the cylinder 31 is fixedly connected to a connecting plate 32, and a lifting and shock absorption component 4 is fixedly connected to the bottom of the connecting plate 32.

[0033] Specifically, when the device height needs to be adjusted, the operator only needs to start the cylinder 31, which will drive the connecting plate 32 to rise and fall through the output end of the cylinder 31, thereby raising and lowering the fixed rod 41. The transmission component 3, as the core component for device height adjustment, works in conjunction with other components such as the lifting and shock absorption component 4, the caster wheel 5, and the push box 1. Through effective height adjustment, it creates good working conditions for the vibration component 10 and vibration component 2 11 and the scraper plate 156, ensuring that the entire device operates stably during concrete construction and improving the overall performance of the equipment.

[0034] like Figures 2 to 3 As shown, the lifting and shock absorption assembly 4 includes a fixed rod 41 fixedly connected to the bottom end of the connecting plate 32, and the fixed rod 41 passes through the push box 1. One end of the fixed rod 41 is fixedly connected inside the hollow cylinder 42, and the fixed rod 41 passes through the hollow cylinder 42. A damper 43 is sleeved on the outer side of one end of the fixed rod 41, and the damper 43 is located inside the hollow cylinder 42.

[0035] Specifically, in concrete construction, the height of the construction surface often varies. The cylinder 31 drives the connecting plate 32 to rise and fall, thereby raising and lowering the fixed rod 41. This lifting function allows the device to be adjusted according to the requirements of different construction heights, ensuring that vibration and leveling operations can be carried out at the appropriate height, improving the accuracy and efficiency of construction. For example, when pouring concrete layers of different thicknesses, the lifting function can be used to position the vibrator 107, vibrator 216, and scraper 156 in the optimal working position. During the movement of the device and vibration operations, a large vibration will be generated. The damper 43 can absorb and dissipate the vibration energy, reducing the impact force of vibration on various components of the device.

[0036] like Figures 4 to 5 As shown, the vibratory assembly 10 includes an eccentric gear 3 101 fixedly installed on the outside of the rotating shaft 3 13. An eccentric gear 4 102 is meshed on the outside of the eccentric gear 3 101. Limiting plates 103 are provided on both sides of the eccentric gear 3 101 and the eccentric gear 4 102 for limiting their positions. Limiting bolts 104 are fixedly installed on the two sets of limiting plates 103 for fixing. A rotating shaft 105 is fixedly installed inside the eccentric gear 4 102. U-shaped seats 106 are fixedly connected to both ends of the rotating shaft 105. A support frame 108 is provided on the outside of the U-shaped seat 106 and is fixedly connected to the rotating shaft 3 13. A vibratory rod 107 is fixedly connected to the bottom end of the U-shaped seat 106 and passes through the support frame 108. The vibratory rod 107 is located on one side of the vibratory assembly 2 11.

[0037] Specifically, when motor 312 starts, its output drives shaft 313 to rotate. Eccentric gear 3101, which is fixedly installed on the outside of shaft 313, rotates accordingly. Eccentric gear 4102, which meshes with eccentric gear 3101, also begins to rotate. Eccentric gear 4102 drives shaft 105 and the connected U-shaped seat 106 and vibrator 107 to perform eccentric motion, generating vibration force to vibrate the concrete and eliminate air bubbles. Limiting plate 103 and limiting bolt 104 play a limiting and fixing role. Support frame 108, through fixed connection with shaft 313, provides a support foundation for the entire vibrating assembly 10, helps maintain the relative position stability of transmission components such as eccentric gear 3101 and eccentric gear 4102, ensures normal gear transmission, and guarantees stable transmission of eccentric gear 3101 and eccentric gear 4102.

[0038] like Figures 4 to 5As shown, the second vibratory assembly 11 includes a connecting rod 111 fixedly installed on a rotating shaft 3 13, and one end of the connecting rod 111 is fixedly connected to a connecting shaft 113. The connecting rod 111 is fixedly connected to a connecting rod 112 through the connecting shaft 113, and one end of the connecting rod 112 is fixedly connected to a connecting shaft 114. A U-shaped seat 115 is fixedly connected to the connecting shaft 114, and a vibratory rod 116 is fixedly connected to the bottom end of the U-shaped seat 115. The vibratory rod 116 is located on one side of the vibratory rod 107.

[0039] Specifically, when motor 312 drives shaft 313 to rotate, connecting rod 111 fixed on the outside of shaft 313 rotates. Connecting rod 111 drives connecting rod 212 to rotate through connecting shaft 113. Connecting rod 212 drives U-shaped seat 215 and vibrator 216 to reciprocate through connecting shaft 214, producing a vibration effect and further eliminating air bubbles in the concrete. Vibrator 107 and vibrator 216 pass through fixing plate 16 inside mounting box 29 to ensure the stability of their movement.

[0040] like Figure 5 As shown, a fixing plate 16 is fixedly installed inside the mounting box 2 9, and vibrating rod 2 116 and vibrating rod 107 respectively pass through the fixing plate 16.

[0041] Specifically, the fixing plate 16 provides positioning for the vibrator 116 and the vibrator 107, limiting their lateral sway during operation, ensuring that the vibrator 116 and the vibrator 107 move stably along the predetermined trajectory, making the vibration operation more precise, improving the vibration effect and concrete quality, ensuring the accurate relative position of the vibrator 116 and the vibrator 107, maintaining the accuracy and consistency of their respective movements, and making the high-frequency and low-frequency vibration work together better.

[0042] like Figure 6 As shown, the adjustable scraper angle assembly 15 includes two sets of semi-circular disks 151 fixedly installed on one side of the bracket 14. A slot 152 is provided in the semi-circular disk 151, and a rod 153 is inserted into the slot 152. A crank 155 is provided on the outside of the rod 153, and the rod 153 is slidably connected to the crank 155. A spring 154 is sleeved on the outer wall of the rod 153, and one end of the spring 154 is fixedly connected to the crank 155. The crank 155 is fixedly connected to the scraper plate 156 through a connecting rod.

[0043] Specifically, during concrete construction, different construction locations and process requirements may require different screeding angles. With the adjustable screed angle component 15, operators can flexibly adjust the angle of the screed plate 156 according to the actual construction conditions, such as the fluidity of the concrete, the pouring thickness, and the inclination of the construction surface. For example, when pouring a thicker concrete layer, the screed plate 156 may need to be adjusted to a larger inclination angle to better spread the concrete. When performing fine surface treatment, the screed plate 156 can be adjusted to a smaller angle to obtain a smoother surface effect.

[0044] Working principle:

[0045] First, the operator pushes the push rod with anti-slip texture on one side of the push box 1, which drives the universal wheel 5 to rotate, making it easy to move the entire device on the concrete construction surface. When encountering concrete construction sections with different heights, the operator starts the cylinder 31. The output shaft of the cylinder 31 drives the connecting plate 32 to rise and fall. The connecting plate 32 drives the fixed rod 41, which is fixedly installed inside, to rise and fall. The damper 43 and the hollow cylinder 42 connected to one end of the fixed rod 41 form a shock absorption structure, which plays a shock absorption and buffering role when the device moves and works. At the same time, it realizes the overall lifting and lowering adjustment of the device to adapt to different construction needs.

[0046] Then, the operator starts servo motor 26. The output of servo motor 26 drives lead screw 7 to rotate. Lead screw 7 drives slider 8, which is connected to the outer thread, to move horizontally. Slider 8 drives vibrating assembly 10 and vibrating assembly 21 through mounting box 29 to vibrate the concrete construction site. After motor 312 starts, it drives shaft 313 to rotate. Since eccentric gear 3101 is fixedly installed on the outside of shaft 313, eccentric gear 3101 rotates synchronously with shaft 313. Eccentric gear 3101 meshes with eccentric gear 4102. When eccentric gear 3101 rotates, it drives eccentric gear 4102 to rotate through the gear meshing principle. Because gear transmission can achieve relatively precise speed transmission and a high transmission ratio in a small space, eccentric gear 4102 can obtain a high speed. When the eccentric gear 102 rotates, it drives the rotating shaft 105 to rotate. The two ends of the rotating shaft 105 are fixedly connected to the U-shaped seat 106. The eccentric gear 102 drives the U-shaped seat 106 and the vibrating rod 107 to make eccentric movements as the eccentric gear 102 rotates. The support frame 108 is fixedly connected to the rotating shaft 13 to help maintain the relative position stability of the transmission components such as the eccentric gear 101 and the eccentric gear 102. Due to the eccentric structure, a periodically changing centrifugal force will be generated during the rotation. This centrifugal force acts on the concrete through the vibrating rod 107 to achieve high-frequency vibration. At the same time, the limiting plate 103 and the limiting bolt 104 restrict the axial movement of the eccentric gear 101 and the eccentric gear 102 to ensure the stability and accuracy of the transmission, thereby ensuring the continuous and stable operation of high-frequency vibration.

[0047] Similarly, when the motor 12 drives the shaft 13 to rotate, the connecting rod 111 fixed on the outside of the shaft 13 rotates. The connecting rod 111 drives the connecting rod 112 to rotate through the connecting shaft 113. The connecting rod 112 drives the U-shaped seat 115 and the vibrator 116 to reciprocate through the connecting shaft 114. Compared with the fast and precise transmission of gear transmission, this mechanical structure transmission of motion through the shaft 13 to drive the connecting rod 111 and the connecting rod 112 has a relatively slow speed and produces low-frequency reciprocating motion. Under the low-frequency reciprocating motion, the vibrator 116 generates low-frequency vibration force, so the high-frequency vibration is used to compact the internal structure of the concrete. The low-frequency vibration helps to remove deep air bubbles. The low-frequency vibration can better fill the corners of the formwork with the concrete. In combination with the high-frequency vibration, the quality of the concrete is further improved.

[0048] After vibration, the concrete surface needs to be leveled. When the device moves on the concrete surface, the scraper plate 156 levels the vibrated concrete surface. It has an adjustable structure consisting of a semi-circular disc 151, a slot 152, a rod 153, a spring 154, and a crank 155. When the leveling angle needs to be adjusted, the rod 153 is pulled so that it can be inserted into the slot 152 in the semi-circular disc 151 as needed under the action of the spring 154. The spring 154 provides a certain elasticity. The rod 153 can adjust the angle of the scraper plate 156 through the crank 155 to adapt to different leveling needs.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
