DETAILED DESCRIPTION

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 As shown in FIG. 4 , an embodiment of the utility model proposes a cement specimen production device, including a base plate 1, a mounting frame 2 is fixedly provided on the top of the base plate 1, a mounting plate 3 is fixedly provided between the inner walls of the mounting frame 2, at least one accommodating tube 4 is provided on the top of the mounting plate 3, and a plurality of overflow holes 5 are opened on the side walls of each accommodating tube 4 along its height direction, and a sliding plate 6 is also horizontally and slidably provided between the inner walls of the mounting frame 2, and the sliding plate 6 is slidably connected to the outer wall of the accommodating tube 4, a sleeve 7 is fixedly provided on the bottom of the sliding plate 6, and the sleeve 7 is slidably sleeved on the outer wall of the accommodating tube 4, and drainage holes 8 corresponding to the positions of the overflow holes 5 are also provided on the outer wall of the sleeve 7, a spring 9 is provided between the sleeve 7 and the mounting plate 3, and a driving component for driving the first slide plate to move downward is also provided in the mounting frame 2. When making cement specimens, the mixture is poured into the accommodating tube 4, and then the driving assembly is started to move the first slide plate downward so that the overflow hole 5 on the accommodating tube 4 is aligned with the drainage hole 8 on the sleeve 7, and then the mixture in the accommodating tube 4 is vibrated and compacted. At this time, excess water will overflow from the overflow hole 5 and be discharged to the outside through the drainage hole 8. After the mixture in the accommodating tube 4 is vibrated and compacted, the driving assembly is released, and the sleeve 7 and the first slide plate move upward under the elastic force of the spring 9, so that the overflow hole 5 and the drainage hole 8 are staggered, and the inner wall of the sleeve 7 closes the overflow hole 5. After waiting for several days, the cement specimen can be obtained. Due to the action of the overflow hole 5 and the drainage hole 8, the excess water in the mixture is discharged to the outside, which speeds up the molding of the cement specimen and also makes the quality of the cement specimen better.

[0021] like Figure 1As shown in FIG. 2, further, the driving assembly includes: a rotating rod 10, both ends of which are movably connected to the inner wall of the mounting frame 2, a cam 11 is fixedly provided on the rod body of the rotating rod 10, and the cam 11 is located above the sliding plate 6. A handle 12 is provided after one end of the rotating rod 10 passes through the mounting frame 2. The rotating rod 10 can be rotatably connected to the inner wall of the mounting frame 2 or threadedly connected. When the first slide plate is driven to move downward, the rotating rod 10 is rotated by the handle 12, so that the raised portion of the cam 11 is pressed against the top of the first slide plate and moves downward with the rotation of the rotating rod 10, so that the drainage hole 8 on the sleeve 7 is aligned with the overflow hole 5. Preferably, in order to prevent the cam 11 from rotating under the action of the spring 9, the raised portion of the cam 11 has a straight edge, so that the side wall where the straight edge is located is pressed against the top of the first slide plate. When the first slide plate is released, the rotating rod 10 is driven in the reverse direction to rotate.

[0022] like Figure 2 —4, further, a through hole communicating with the interior of the receiving tube 4 is provided on the mounting plate 3, a hydraulic cylinder 13 is fixedly provided on the top of the bottom plate 1, a push plate 14 is horizontally and fixedly provided on the output end of the hydraulic cylinder 13, the push plate 14 is also slidably connected to the inner wall of the mounting frame 2, a blocking block 15 is fixedly provided on the top of the push plate 14, and the blocking block 15 is dynamically sealed and connected to the through hole on the mounting plate 3. When the hydraulic cylinder 13 is not started, the blocking block 15 is located in the through hole of the mounting plate 3. It should be noted that the size of the mounting hole 20 is the same as the inner diameter of the receiving tube 4. After the mixture in the receiving tube 4 solidifies, the hydraulic cylinder 13 is driven multiple times, so that the hydraulic cylinder 13 pushes the push plate 14 back and forth to move upward, so that the blocking block 15 pushes the solidified cement specimen upward to achieve the demoulding effect. Similarly, the hydraulic cylinder 13 can be replaced with a cylinder or an electric push rod.

[0023] like Figure 2 As shown in FIG. 3 , further, a plurality of sliders 16 are provided on the circumferential side wall of the push plate 14, and a slide groove corresponding to the sliders 16 is provided on the inner wall of the mounting frame 2, and the push plate 14 is slidably connected with the slide groove through the sliders 16. Through the slidable connection between the sliders 16 and the slide groove, the push plate 14 is guided by the slide groove during the upward movement, so that the movement in the vertical direction is more stable.

[0024] like Figure 2 As shown in FIG. 4 , the device further includes a water collecting ring 17, which is fixedly arranged on the top of the mounting plate 3, and the receiving tube 4 is located in the water collecting ring 17. In this embodiment, there are two receiving tubes 4, both of which are located in the water collecting ring 17. The water collecting ring 17 and the mounting plate 3 form a water collecting space, which collects the water discharged from the drain hole 8 to prevent this part of the water from polluting other areas of the device.

[0025] like Figure 2—4, further, it also includes a water collecting box 18, which is fixedly arranged on the top of the base plate 1, and one end of a hose 19 is provided at the bottom of the mounting plate 3, and the hose 19 is connected to the water collecting ring 17, and the other end of the hose 19 is connected to the water collecting box 18. Specifically, an inclined surface is provided in the water collecting box 18, and the connection point between the hose 19 and the water collecting ring 17 is located at the lowest end of the inclined surface, so that the water in the water collecting ring 17 is easily discharged into the water collecting box 18, thereby avoiding excessive overflow of the water in the water collecting ring 17.

[0026] like Figure 1 As shown in FIG. 2 , further, both ends of the bottom plate 1 are provided with mounting holes 20. The mounting holes 20 facilitate the bottom plate 1 of the device to be leveled and fixed to the outside, so as to avoid the movement of the device during the production of the cement specimen, thereby affecting the molding effect of the cement specimen.

[0027] like Figure 3 As shown in FIG. 4 , further, a vibrator 21 is provided at the bottom of the mounting plate 3. The vibrator 21 vibrates the mixed material in the containing tube 4 to make the mixed material more compact and reduce the excess moisture between the mixed materials.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
