[0002] A concrete specimen vibration device is a piece of equipment suitable for forming specimens and vibrating precast components such as slabs, columns, and beams in laboratories and on-site construction sites. Concrete specimens are used to determine the compressive strength of concrete. In my country, cubic specimen molds are used for concrete compressive strength testing. However, since 20 cm cubic specimen molds and blocks are too heavy and wasteful of materials, 15 cm cubic specimen molds and blocks are generally used.
[0003] An existing concrete specimen vibration device (announcement number: CN215702546U) has at least the following drawbacks:
[0004] In the aforementioned patent, concrete is received by a set receiving box. However, during the vibration process, the concrete will spill onto the vibrating table and needs to be cleaned manually. If it is not cleaned properly, it will cause cement to solidify and adhere, making the vibrating table dirty. Therefore, it is necessary to propose a concrete specimen vibration device to solve the above problems. Utility Model Content

The anti-fouling component also includes a second limiting plate 9 fixedly sleeved inside the support plate 5, with a limiting hole 10 on one side of the second limiting plate 9; and a fixing box 11 fixedly installed on one side of the support plate 5, with a utility knife 12 disposed inside the fixing box 11.
[0027] When using the device, if the user needs to vibrate the concrete specimen, the protective membrane 4 is pulled to rotate and unwind the winding roller 7, covering the entire top surface of the platform 2. Then, a utility knife 12 is used to cut the edge of the protective membrane 4 and insert the blade into the limiting hole 10. The utility knife 12 cuts along the limiting hole 10, ensuring a straight cut and preventing misalignment. The concrete specimen is then placed on top of the protective membrane 4, and the vibration motor of the vibration table body 1 is started to vibrate the platform 2 and the concrete specimen. During vibration, mortar is sprayed out, which is then isolated from the platform 2 by the protective membrane 4, preventing the platform 2 from getting dirty. After vibration, the specimen is removed, and the concrete is collected by scooping up the protective membrane 4 along with the mortar, making it convenient to use.
[0028] In this embodiment, a protective chamber 13 is provided on one side of the support plate 5. Several hinges 14 are fixedly installed on the bottom surface of the protective chamber 13. The protective chamber 13 is connected to the support plate 5 through the hinges 14. Several threaded posts 16 are fixedly installed on the bottom surface of the table 2. Several connecting holes 15 are opened on the top surface of the vibration table body 1. The connecting holes 15 are movably connected to the threaded posts 16. Nuts 17 are threadedly connected to the outer circular wall surface of the threaded posts 16.
[0029] In use, the fixed surface 2 can be released by rotating the nut 17, and the surface 2 can be lifted up to remove it. When the surface 2 inevitably rusts, deforms and gets dirty after long-term use, it can be replaced.
[0030] In this embodiment, a second fixing plate 18 is fixedly installed on both sides of the vibration table body 1. The top surface of the second fixing plate 18 is provided with a plurality of mounting holes 19. The inner wall of the support hole 6 is arc-shaped from top to bottom and from left to right, and the slope of the inner wall gradually decreases. The top surface of the second limiting plate 9 is provided with an arc-shaped chamfer.
[0031] When in use, when the protective film 4 is pulled to unwind the winding roller 7, the winding roller 7 is inside the support hole 6, which supports the winding roller 7 and prevents it from slipping. When it is necessary to remove the winding roller 7, simply move it to the upper left. Disassembly is simple.
[0032] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the user needs to vibrate a concrete specimen using the vibration table body 1, the protective film 4 is pulled to rotate and unwind the take-up roller 7, covering the entire top surface of the table 2. Then, a utility knife 12 is used to cut the edge of the protective film 4 and insert its blade into the limiting hole 10. The utility knife 12 cuts along the limiting hole 10, ensuring a straight cut and preventing misalignment. The concrete specimen is then placed on top of the protective film 4, and the vibration motor of the vibration table body 1 is started to vibrate the table 2 and the concrete specimen. Mortar will be sprayed out during vibration. The protective film 4 isolates the mortar and the countertop 2, preventing the countertop 2 from getting dirty. After compaction, the specimen is removed, and the concrete can be recycled by lifting the protective film 4 along with the mortar. This is convenient for use. The protective film 4 can be a biodegradable film with increased thickness to reduce environmental pollution. When the protective film 4 is used up, the protective chamber 13 is rotated, and the take-up roller 7 is lifted and taken out from the inside of the support hole 6. A new protective film 4 can then be wrapped around the outside of the take-up roller 7 and put back for continued use. This comprehensively prevents the countertop 2 from being spilled with concrete and causing dirt to adhere, making it convenient for users to clean up spilled concrete. At the same time, lifting the take-up roller 7 and taking it out from the inside of the support hole 6 allows for the wrapping of a new protective film 4 or direct replacement of the take-up roller 7 and the protective film 4, making it convenient and practical for use.
