[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 In this embodiment of the present invention, a cement mortar vibration table for cement sample testing includes a vibration table 1 with a vibration motor 2 installed at the bottom. Sliding legs 3 protruding downwards are fixedly installed at the four corners of the bottom of the vibration table 1. Fixed legs 4, which are fixed to the ground, are slidably installed on the outer wall of the sliding legs 3. A connecting ring 5 is integrally formed on the outer wall of the sliding legs 3 above the fixed legs 4. A vibration spring 6 abuts between the bottom end of the connecting ring 5 and the top end of the fixed legs 4. The vibration spring 6 is sleeved on the outer periphery of the sliding legs 3. Two symmetrically distributed guide rails 7 are fixedly installed at the top of the vibration table 1. A one-way mechanism is installed at the inlet end of the guide rail 7, and a blocking mechanism is installed at the outlet end of the guide rail 7. A pushing mechanism is provided on the top of the vibration table 1 outside one of the guide rails 7 to limit the blocking mechanism when it moves to its lowest position.

[0019] In this embodiment: First, after the mortar is loaded into the mold, the protruding parts on both sides of the mold are inserted into the inner side of the two guide rails 7 and pushed in. At this time, the protruding parts of the mold squeeze the one-way mechanism. The one-way mechanism moves until the mold and the one-way mechanism are misaligned. Then, the one-way mechanism resets and covers the mold. At this time, the vibration motor 2 is started. When the vibration motor 2 runs, it generates vibration force. Under the vibration force, the sliding leg 3 moves up and down on the inner wall of the fixed leg 4. At this time, the connecting ring 5 moves up and down with the sliding leg 3, compressing the vibration spring 6. After compression, the vibration spring 6 resets, forming a reciprocating vibration effect. At this time, the moisture in the mortar in the mold is more evenly distributed under the vibration force. Secondly, the gas in it overflows outward under the vibration, ensuring that the mortar in the mold can be more evenly distributed, avoiding the problem of uneven distribution of moisture and gas after curing affecting the strength test results.

[0020] Please refer to this carefully. Figure 4 and Figure 5 The one-way mechanism includes a first fixing block 20 fixedly installed on the top of the vibration table 1 and located outside the guide rail 7. A guide shaft 21 is slidably connected to the inner wall of the first fixing block 20. A sliding block 14 that penetrates to the inside of the guide rail 7 is fixedly installed at one end of the guide shaft 21. A fixing spring 23 abuts between the end of the sliding block 14 located outside the guide rail 7 and the first fixing block 20. The fixing spring 23 is sleeved with the guide shaft 21. A pressure-bearing inclined surface 22 is integrally formed at the end of the sliding block 14 located inside the guide rail 7.

[0021] In this embodiment: when the test mold is inserted, the protruding part at the bottom of the outer side of the test mold comes into contact with the pressure inclined surface 22 during the sliding process and is squeezed. At this time, the sliding block 14 is moved by force and compresses the fixed spring 23, while driving the guide shaft 21 to slide until the test mold is misaligned with the one-way mechanism. At this time, the fixed spring 23 is reset, and the reset fixed spring 23 drives the sliding block 14 to reset. During the vibration process, the flat end of the sliding block 14 limits the test mold to prevent it from moving outward. In addition, during the vibration process, a new test mold can be put in at any time without affecting the already vibrated test mold.

[0022] Please refer to this carefully. Figure 2 The blocking mechanism includes a guide sleeve 8 fixedly installed at one end of the vibrating table 1 and located below the outlet end of the guide rail 7. A blocking plate 9 extending to the bottom of the vibrating table 1 is slidably connected to the inner wall of the guide sleeve 8. A protruding block 10 is integrally formed on the top of the blocking plate 9. A receiving groove 11 for accommodating the protruding block 10 is provided on the top of the guide sleeve 8. A guide ring 12 that is slidably connected to the horizontal plate of the blocking plate 9 is fixedly installed at the bottom end of the receiving groove 11. A return spring 13 abuts between the top end of the protruding part at the bottom end of the guide ring 12 and the bottom end of the horizontal plate of the blocking plate 9. The return spring 13 is sleeved on the outer periphery of the guide ring 12.

[0023] In this embodiment: after the placed test mold has reached the vibration time, the blocking plate 9 is pressed down. The blocking plate 9 moves down along the guide ring 12. At this time, the reset spring 13 is compressed until the protruding block 10 is completely inserted into the receiving groove 11. At this time, the push mechanism is reset, blocking the blocking plate 9 which has moved to the lowest position. At this time, the top of the blocking plate 9 is flush with the top surface of the vibration table 1, and the test mold can be taken out without affecting the test molds placed later.

[0024] Please refer to this carefully. Figure 2 and Figure 3The pushing mechanism includes a second fixed block 15 fixedly installed on the top of the vibration table 1 and located outside a guide rail 7. A sliding rod 16 is slidably installed inside the second fixed block 15. A limiting block 17 with an "L" shaped structure is fixedly installed at one end of the sliding rod 16. An upwardly protruding handle 19 is fixedly installed at the top of the horizontal bar of the limiting block 17. A connecting spring 18 abuts between the vertical bar of the limiting block 17 and the second fixed block 15. The connecting spring 18 is sleeved on the outer periphery of the sliding rod 16. The blocking plate 9 coincides with the limiting block 17 in the width direction.

[0025] In this embodiment: when the blocking plate 9 moves down to the lowest position, the connecting spring 18 resets and pushes the limiting block 17 to move. The reset limiting block 17 blocks the top of the blocking plate 9, and the blocking plate 9 is restricted to the lowest position. After the test mold is taken out, the handle 19 is pushed to move, and the handle 19 drives the limiting block 17 to move and compresses the connecting spring 18. After the limiting block 17 and the blocking plate 9 are misaligned, the connecting spring 18 resets and pushes the blocking plate 9 to reset upward, blocking the subsequent insertion of the test mold.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
