Description

Technical Field

[0001] This utility model relates to the field of cement mortar mixing technology, specifically a vibration device for reducing air bubbles in cement mortar. Background Technology

[0002] Utility model application CN202321217927.1 discloses a cement mixer. Through a water storage chamber, connecting pipe, distribution cylinder, and spray nozzles, water can be added to the cement when it is relatively dry. A second motor enables the rotation of the connecting pipe, distribution cylinder, and spray nozzles, allowing water to be evenly distributed into the cement through rotational spraying. A second cylinder allows for left-right movement, enabling omnidirectional water addition, improving the water addition effect, and reducing the difficulty of mixing.

[0003] The aforementioned device uses a rotating spray method to evenly replenish water into the cement. However, adding water to the cement mortar during the mixing process can easily introduce air, causing air bubbles to form in the cement mortar. These air bubbles cannot be eliminated, and they affect the strength and performance of the cement mortar. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a vibration device to reduce air bubbles in cement mortar.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A vibration device for reducing air bubbles in cement mortar, comprising: Mortar mixer; Fixed base for supporting the mortar mixer; A lifting ring plate is sleeved on a mortar mixer, and there is a gap between the inner ring of the lifting ring plate and the outer wall of the mortar mixer. A vibration defoaming component is used to strike the outer wall of the mortar mixer. The vibration defoaming component is mounted on a lifting ring plate so that the vibration defoaming component moves with the lifting ring plate.

[0006] Furthermore, the vibration defoaming assembly includes a movable ring, with guide grooves at both ends of the lifting ring plate. Guide slides are slidably connected within the guide grooves. The bottom end of the movable ring is fixedly connected to the surface of the guide slides. A right rubber hammer is installed on the right side of the inner wall of the movable ring, and a left rubber hammer is installed on the left side of the inner wall of the movable ring. A fixed side plate is installed on one side of the surface of the lifting ring plate, and a guide slide rod is installed on one side of the movable ring. The guide slide rod passes through the fixed side plate and is slidably connected to it. A vibration spring is fitted onto the guide slide rod, and the vibration spring is located between the fixed side plate and the movable ring. A drive motor is installed on the other side of the surface of the lifting ring plate, and an eccentric wheel is connected to the output end of the drive motor via a rotating shaft.

[0007] Furthermore, there are three right and three left rubber hammers that are evenly distributed in a ring on the inner wall of the moving ring. The right rubber hammer contacts the side wall of the mortar mixer through the force of the vibration spring.

[0008] Furthermore, a vertical sliding rod is fixedly installed on the surface of the fixed base. Four vertical sliding rods are arranged in a ring and evenly distributed on the surface of the fixed base. Four guide sleeves are connected to the surface of the lifting ring plate. The guide sleeves are slidably connected to the vertical sliding rods. A rotary motor is installed on the fixed base. A threaded screw is installed at the output end of the rotary motor. The threaded screw passes through the lifting ring plate. A threaded lifting slider is provided on the threaded screw. The lifting slider is fixedly connected to the lifting ring plate.

[0009] Furthermore, a limiting plate is fixedly connected to the vertical sliding rod. The limiting plate is located below the lifting ring plate. Support columns are installed at the four corners of the bottom surface of the limiting plate, and the bottom ends of the support columns are fixedly connected to the fixed base.

[0010] The lifting ring plate is limited to its lowest position by a limiting plate, and the lifting ring plate is supported by the limiting plate and the support column, which improves the support strength. When the lifting ring plate is in its lowest position, the staff can stand on the lifting ring plate to observe the mixing situation inside the mortar mixer.

[0011] Furthermore, the diameter of the fixed base is the same as the outer diameter of the lifting ring plate, and the bottom surface of the fixed base is provided with anti-slip texture.

[0012] The mortar mixer is supported by a fixed base, and the anti-slip texture prevents it from shifting when struck or vibrated.

[0013] Compared with existing technologies, this technical solution has the following beneficial effects: 1. The eccentric wheel and vibration spring cause the moving ring to move back and forth, which in turn drives the left and right rubber hammers to move back and forth and strike the wall of the mortar mixer. The striking causes the wall of the mortar mixer to vibrate, and the vibration is transmitted to allow the air bubbles inside the cement mortar to be discharged along the gaps in the wall or the surface of the mortar, which improves the defoaming effect, the strength of the cement mortar, and the performance of the cement mortar. 2. The lifting ring plate is guided by the vertical slide bar and guide sleeve to make the lifting ring plate rise and fall vertically, so as to avoid the position of the lifting ring plate being offset. The lifting ring plate drives the vibration defoaming component to move from bottom to top. The vibration transmission efficiency is the highest at the bottom of the mortar mixer, which improves the defoaming effect. There is no need to knock above the cement mortar level to avoid the vibration of the barrel wall causing mortar to splash. 3. After the cement mortar is discharged, the material adhering to the barrel wall can be cleaned off by tapping and vibration, which improves the cleanliness of the barrel and eliminates the need for manual cleaning of the barrel wall, thus reducing the intensity of manual labor.

Vibration defoaming component 4 is used to strike the outer wall of mortar mixer 1. Vibration defoaming component 4 is set on lifting ring plate 3 so that vibration defoaming component 4 moves with lifting ring plate 3.

[0023] The materials to be mixed are poured into the mortar mixer 1 and mixed by the mortar mixer 1. During the mixing process, the vibrating defoaming component 4 taps and vibrates the barrel wall of the mortar mixer 1. The vibration is transmitted to allow the air bubbles inside the cement mortar to be discharged along the gaps in the barrel wall or the surface of the mortar. The vibrating defoaming component 4 is moved from bottom to top by the lifting ring plate 3. The air bubbles are most likely to accumulate at the bottom. The vibration transmission efficiency is the highest at the bottom of the mortar mixer 1, which improves the defoaming effect, increases the strength of the cement mortar, and improves the use effect of the cement mortar. There is no need to tap above the cement mortar level to avoid the mortar splashing caused by the vibration of the barrel wall. After the cement mortar is discharged, the material attached to the barrel wall can be cleaned off by tapping and vibration, which improves the cleanliness of the barrel.
