[0030] A cement mortar vibrating table provided in this embodiment is referred to Figures 1-4As shown in the figure, it includes a support plate 1. A bottom plate 11 is provided on the bottom surface of the support plate 1. A sliding rod 12 is connected to the side of the support plate 1. A slider 2 is inserted through the sliding rod 12. A connecting column 21 is provided on the upper part of the slider 2. Two limiting rods 211 are connected to the side surface of the connecting column 21. A mold groove 3 is placed between the two limiting rods 211. A bracket 4 is provided on the side of the sliding rod 12. A support foot 41 is provided at the lower end of the bracket 4. A vibration table 5 is installed on the upper end surface of the bracket 4. A housing 51 is provided outside the vibration table 5. An opening is provided at one end of the housing 51. A cover plate 52 is installed on the opening end surface of the housing 51. Cavities 54 connected to a vacuum valve 53 are respectively provided inside the cover plate 52 and the housing 51.
[0031] In the above embodiment, a bottom plate 11 is provided on the bottom surface of the support plate 1, and the support plate 1 is connected to the bottom plate 11. The bottom plate 11 increases the contact area between the support plate 1 and the ground, which is beneficial to improving the stability of the support plate 1. A slide bar 12 is connected to the side surface of the support plate 1, and a slider 2 is inserted on the slide bar 12. The slider 2 can move along the set direction of the slide bar 12. Optionally, the number of slide bars 12 is three and they are distributed and connected on the side surface of the support plate 1 in an "inverted triangle" shape, which increases the sliding connection points between the slider 2 and the slide bar 12 and is beneficial to improving the stability of the slider 2 when sliding on the slide bar 12. A connecting column 21 is provided on the upper part of the slider 2, and two limiting rods 211 are connected to the side surface of the connecting column 21. A mold groove 3 is placed between the two limiting rods 211, and the two side edges of the mold groove 3 are respectively in contact with the two limiting rods 211, so that the limiting rods 211 lift the mold groove 3. A bracket 4 is provided on the side of the slide bar 12, and a vibrating table 5 is installed on the upper end surface of the bracket 4. In the initial state, the slider 2 is located on one side close to the support plate 1. Cement mortar is poured into the mold groove 3 for preparation. After the cement mortar is prepared, the slider 2 is pushed, and the slider 2 is moved to one side of the vibrating table 5. The sliding push of the slider 2 is smoother than the manual transfer of the groove mold by the staff. Since the cement mortar has a certain self-weight, it is more labor-saving than holding the mold groove 3 by hand, which is beneficial to improving the compaction efficiency. In addition, compared with directly preparing cement mortar on the compaction table, it can prevent the cement mortar material from splashing on the compaction table surface and being inconvenient to clean, or the normal operation of the compaction table being affected after the cement mortar solidifies. A housing 51 is provided outside the vibrating table 5. The housing 51 can block the noise generated by the vibrating table 5 and prevent the noise from spreading outwards. Further, an opening is provided at one end of the housing 51 for placing the mold groove 3 on the vibrating plate for compaction. A cover plate 52 is installed on the opening end surface of the housing 51. One side edge of the cover plate 52 is rotatably connected to the upper end surface of the housing 51. When the mold groove 3 is placed, the cover plate 52 is turned upwards to place the mold groove 3, and after placing, the cover plate 52 is turned downwards to close the opening of the housing 51. In addition, the cover plate 52 and the housing 51 are of a hollow design, that is, cavities 54 connected to a vacuum valve 53 are respectively provided inside the cover plate 52 and the housing 51. The air in the cavities 54 is pumped away through the vacuum valve 53 to form a vacuum layer. Since the propagation of sound requires a medium, the vacuum layer inside the cover plate 52 and the housing 51 reduces the medium for noise propagation. Therefore, the noise generated by the vibrating table 5 can be reduced to avoid the propagation and diffusion of noise and reduce the noise pollution during the operation of the compaction table, protecting the physical and mental health of the test personnel.
[0032] In an embodiment of the present application, referring to Figure 2 as shown, soft protrusions 55 are provided on the side wall surfaces of the cover plate 52 and the housing 51 facing the vibrating table 5.
[0033] In the above embodiment, the soft protrusion 55 can be selected as a rubber block. On the one hand, the soft protrusion 55 can increase the wall thickness of the cover plate 52 and the housing 51 to isolate the noise propagation. On the other hand, when the noise sound wave generated by the vibrating table 5 is transmitted between the soft protrusions 55, the soft protrusions 55 can absorb the sound wave energy and convert the sound wave energy into internal vibration heat energy to consume the sound wave energy, thereby benefiting the reduction of noise propagation.
[0034] In one embodiment of the present application, refer to Figure 2 As shown, a fixing groove 56 is formed on the upper end surface of the vibrating table 5.
[0035] In the above embodiment, the fixing groove 56 is used to place the mold groove 3, and the fixing groove 56 plays a role in limiting the mold groove 3, preventing the mold groove 3 from moving relatively on the vibrating table 5 when the mold groove 3 contacts the vibrating table 5, so that the cement mortar in the mold groove 3 spills, which is beneficial to improving the stability of the mold groove 3 when the vibrating table 5 works.
[0036] In one embodiment of the present application, refer to Figure 2 As shown, the connecting column 21 is connected to the slider 2 through the telescopic rod 6.
[0037] In the above embodiment, the slider 2 is pushed to move the mold groove 3 above the vibrating table 5 through the limiting rod 211, the telescopic rod 6 is controlled to contract downward to place the mold groove 3 in the fixing groove 56 on the upper end surface of the vibrating table 5, and then the slider 2 is pushed in the reverse direction to withdraw the limiting rod 211 from both sides of the mold groove 3. Similarly, when the cement mortar is vibrated and compacted, the limiting rod 211 is inserted below the edge of the mold groove 3, the telescopic rod 6 is controlled to extend upward to lift the mold groove 3 from the fixing groove 56, and then the slider 2 is pushed in the direction away from the vibrating table 5 to take out the mold groove 3 from the fixing groove 56, which is beneficial to improving the stability of the mold groove 3 when it is placed and taken out.
[0038] In one embodiment of the present application, refer to Figure 3 As shown, a threaded hole is formed on the side wall of the fixing groove 56, and a fastening bolt 561 is fitted in the threaded hole.
[0039] In the above embodiment, there will be a gap when the mold groove 3 is placed in the fixing groove 56. When the vibrating table 5 vibrates, the outer wall of the mold groove 3 will collide with the inner wall of the fixing groove 56 to generate abnormal noise, or the mold groove 3 will shake violently in the fixing groove 56 to cause the cement mortar in the mold groove 3 to spill. At this time, the fastening bolt 561 is screwed into the fixing groove 56 from the threaded hole to tighten the mold groove 3 in the fixing groove 56 to improve the stability of the mold groove 3 in the fixing groove 56.
[0040] In one embodiment of the present application, refer to Figure 4As shown, an installation frame 7 is connected to the side of the bottom plate 11. A mixing tank 71 is provided on the installation frame 7, and a material guiding pipe 72 is connected to the lower part of the mixing tank 71.
[0041] In the above embodiment, the mixing tank 71 is used to mix and stir the cement mortar during the preparation process, which is beneficial to improving the uniformity of the cement mortar, and thus improving the accuracy of the cement mortar test. A valve is installed on the material guiding pipe 72. After the cement mortar is stirred, the mold groove 3 is moved to the lower part of the material guiding pipe 72, and the valve is opened to introduce the cement mortar into the mold groove 3 through the material guiding pipe 72.
[0042] In an embodiment of the present application, refer to Figure 4 As shown, a buffer pad 411 is provided at the lower part of the support leg 41.
[0043] In the above embodiment, a vibrating table 5 is provided on the support 4. The vibration generated by the vibrating table 5 will also be transmitted to the ground or floor through the support legs 41 at the lower part of the support 4, causing vibration of the ground or floor. A buffer pad 411 is provided at the lower part of the support leg 41 to buffer the vibration of the support leg 41 through the elasticity of the buffer pad 411, so as to prevent the vibration of the vibrating table 5 from being transmitted to the ground through the support leg 41 to generate noise or cause the floor slab to become loose. Optional materials for the buffer pad 411 include rubber, foam (polyurethane foam), gel, etc.
[0044] During the actual use of the present application: The cement mortar is prepared in the mold groove 3. The two side edges of the mold groove 3 are respectively in contact with the two limit rods 211, so that the limit rods 211 lift the mold groove 3. A support 4 is provided on the side of the sliding rod 12, and a vibrating table 5 is installed on the upper end surface of the support 4. In the initial state, the slider 2 is located close to the support plate 1. The cement mortar is poured into the mold groove 3 for preparation. After the cement mortar is prepared, the slider 2 is pushed, and the slider 2 is moved to one side of the vibrating table 5. A housing 51 is provided outside the vibrating table 5. The housing 51 can block the noise generated by the vibrating table 5 to prevent the noise from spreading outward. Further, an opening is provided at one end of the housing 51 for placing the mold groove 3 on the vibrating plate for compaction. A cover plate 52 is installed on the opening end surface of the housing 51. One side edge of the cover plate 52 is rotatably connected to the upper end surface of the housing 51. When placing the mold groove 3, the cover plate 52 is turned upward to place the mold groove 3, and after placing, the cover plate 52 is turned downward to close the opening of the housing 51. In addition, the cover plate 52 and the housing 51 are of a hollow design, that is, cavities 54 connected to a vacuum valve 53 are respectively provided inside the cover plate 52 and the housing 51. The air in the cavities 54 is pumped away through the vacuum valve 53 to form a vacuum layer. The vacuum layers inside the cover plate 52 and the housing 51 reduce the medium for noise propagation, so the noise generated by the vibrating table 5 can be reduced.
