[0024] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Embodiment 1 of the present utility model:

[0026] like Figure 1-Figure 2As shown, a vibration table for cement concrete density detection includes a support platform 1, a support frame 2 fixedly mounted on the support platform 1, and a scraping device 3 slidably mounted on the support frame 2. The shape of the support platform 1 can be designed into various shapes as needed. Here, the support platform 1 is a rectangle as an example. A support base 9 is provided at the bottom of the support platform 1. The support platform 1 and the support base 9 are connected by a spring 10. A vibration motor is fixedly installed at the bottom of the support platform. There are two support frames 2, and the two support frames 2 are symmetrically arranged on an opposite edge of the upper surface of the support platform 1, so that the support frame 2 can avoid affecting the placement of the capacity cylinder. The scraping device 3 is slidably installed between the two support frames 2. The scraping device 3 includes a scraper 301 and a trowel plate 302. The scraper 301 is vertically arranged with the support platform 1, and the trowel plate 302 is parallel to the support platform 1. The trowel plate 302 is fixedly installed on one side of the scraper 301 and is located at the lower end of the scraper 301. The lower surface of the trowel plate 302 is flush with the lower end surface of the scraper 301. The trowel plate 302 and the scraper 301 form an L-shaped structure. Specifically, when the scraping device 3 is installed on the support frame 2, the lower end of the scraping device 3, that is, the lower end surface of the end on which the trowel plate 302 is installed, is exactly flush with the upper end of the capacity cylinder placed on the support platform 1. In this way, it can be ensured that after the capacity cylinder vibrates, by moving the scraping device 3, the scraper 301 can scrape off the excess concrete at the cylinder mouth and smooth the cylinder mouth, and the trowel plate 302 can further smooth the cylinder mouth while checking whether the cylinder mouth is smoothed. For easy observation, the trowel plate 302 is selected as a transparent plate, such as glass, a transparent plastic plate, etc.

[0027] like Figure 3-Figure 4 As shown, further, the support frame 2 can be a U-shaped frame, the U-shaped frame is provided with a slide groove 201 in the horizontal direction, a slide bar 4 is fixedly installed in the slide groove 201, both ends of the scraper 301 are fixedly connected to a slider 5 through a connecting rod, the slider 5 cooperates with the slide groove 201, and a slide hole adapted to the slide bar 4 is provided on the slider 5. Such a design can ensure the smoothness of the scraping device 3 when it moves, and at the same time can prevent the scraping device 3 from flipping when it moves along the slide bar 4, thereby improving the stability of the scraping device 3 during movement.

The connecting plate 6 and the slide bar 4 and the inner wall of the chute 201 can be fixedly connected by welding. The avoidance hole 501 is arranged on the slider 5 to effectively avoid the friction between the slider 5 and the connecting plate 6 during the sliding process. The chute 201 is designed as a through chute, which is convenient for removing the scraping device 3 from the vibration table. In this way, it is convenient to remove the scraping device 3 from the vibration table before the vibration starts, so as to avoid damage to the scraping device 3 during the vibration process, and it is also convenient to remove and clean the scraping device 3 after use.

[0030] Furthermore, to facilitate the installation and disassembly of the scraping device 3, the slide groove 201 can be opened on the opposite sides of the two U-shaped frames, and the slide groove 201 extends from both ends of the slide rod 4. In this way, the installation efficiency of the scraping device can be improved, making the scraping device easier to install on the U-shaped frame.
