After vibration, the sample is removed. However, this method results in a single vibration direction for the sample and a relatively limited experimental factor for the vibration of the cement mortar specimen, which affects the accuracy of the experiment.

[0010] The beneficial effects of this utility model are:

[0011] When conducting vibration experiments on cement mortar, the cement mortar is first placed into the various vibration grooves within the mold. After placement, a baffle is installed on the mold. Then, by operating the second vibration component, the cement mortar inside the mold vibrates horizontally.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Example

[0018] Please refer to Figures 1-3 A cement mortar vibrating table includes a mold 4 for placing cement mortar. The bottom of the mold 4 is provided with a first vibration assembly, which includes a top plate 6, a bottom plate 2, and a vibrating element. The vibrating element is located between the top plate 6 and the bottom plate 2 and is used to drive the top plate 6 to rotate in the vertical direction. A rotating part is provided between the mold 4 and the top plate 6 and is used to drive the mold 4 to rotate in the horizontal direction. A second vibration assembly is provided below the bottom plate 2 and is used to drive the bottom plate 2 to vibrate in the horizontal direction.

[0019] In an optional embodiment: the interior of the mold 4 is divided into pairs of vibration troughs for placing cement mortar by multiple partitions 40. The top of the mold 4 is detachably connected to a baffle 8, and the edge of the baffle 8 has a mounting block 81. The baffle 8 is connected to the mold 4 by screws 82. During the vibration test of cement mortar, after the cement mortar is placed in the vibration trough, the baffle 8 separates the cement mortar in the vibration trough to prevent it from overflowing during vibration.

[0020] In an optional embodiment: the top plate 6 is provided with a mounting groove 61, the rotating part includes a drive motor 7, the drive motor 7 is installed in the mounting groove 61, the output shaft of the drive motor 7 is connected to the bottom center of the mold 4, the bottom of the top plate 6 is also provided with an annular groove 60, the bottom of the mold 4 has an annular slider 41, the annular slider 41 is slidably connected in the annular groove 60, through the cooperation of the annular slider 41 and the annular groove 60, the drive motor 7 can drive the mold 4 to rotate more stably. Specifically, the cross-sectional area of ​​the annular groove 60 is T-shaped to prevent the mold 4 from detaching from the top plate 6.

[0021] In an optional embodiment: the vibrating element includes a second drive motor 5 disposed between the bottom plate 2 and the top plate 6, the output shaft of the second drive motor 5 is connected to a second cam 51 that acts on the top plate 6, and each of the four bottom corners of the top plate 6 is provided with a telescopic sleeve 3, the telescopic sleeve 3 is connected between the bottom plate 2 and the top plate 6, and a second spring 31 is sleeved on the surface of the telescopic sleeve 3.

[0022] In an optional embodiment: the second vibration assembly includes a base frame 1, the inner wall of the base frame 1 has two sets of opposing slide rails 11, a movable block 12 is slidably connected on the slide rails 11, one end of the movable block 12 away from the slide rails 11 is fixedly connected to the base plate 2, a roller 13 is installed on one side of the movable block 12, a drive motor 14 is provided on one side of the roller 13, the drive motor 14 is installed inside the base frame 1, the output shaft of the drive motor 14 is equipped with a cam 15 adapted to the roller 13, a telescopic sleeve rod 16 is connected to the side of the movable block 12 away from the roller 13, the other end of the telescopic sleeve rod 16 is connected to the inner side of the base frame 1, and a spring 17 is sleeved on the surface of the telescopic sleeve rod 16.

[0023] Specifically, by starting the drive motor 14, the cam 15 is rotated. When the tip of the cam 15 approaches the roller 13, it will drive the base plate 2 and the top plate 6 connected to the movable block 12 to move in one direction and compress the spring 17. When the tip of the cam 15 moves away from the roller 13, the movable block 12 will be driven by the action of the spring 17 to reset the base plate 2 and the top plate 6. Thus, the vibration component 2 drives the top plate 6 above the base plate 2 to vibrate in the horizontal direction.

[0024] Specifically, when conducting a vibration experiment on cement mortar, the cement mortar is first placed into the various vibration grooves within the mold 4. After placement, it is installed on the mold 4 via a baffle 8. Then, by operating the second vibration component, the cement mortar inside the mold 4 vibrates horizontally. By operating the rotating part, the mold 4 is rotated horizontally, changing the position of the cement mortar inside the mold 4. This alters the position of the cement mortar in contact with the inner wall during vibration in the vibration groove. Then, by operating the second drive motor 5, the second cam 51 vibrates the top plate 6 vertically, thereby vibrating the cement mortar in the mold 4 in the vertical direction. This allows for multi-directional vibration of the cement mortar within the mold 4, increasing the experimental factors related to cement mortar vibration and improving experimental accuracy.
