Detailed Implementation
[0031] 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.
[0032] refer to Figure 1-3 A concrete sample preparation device includes: a vibration mechanism 1, a mold 2, a support frame 3, and an injection mechanism 4. The vibration mechanism 1 has a vibrating table 11; the mold 2 is used to store shaped concrete and is placed on the vibration table 11; the support frame 3 is disposed on one side of the vibration mechanism 1 and has a base plate 31 located above the vibration table 11; the injection mechanism 4 is vertically mounted on the base plate 31 and is used to automatically inject concrete into the mold 2.
[0033] Understandably, the vibration mechanism 1 is the component that drives the test mold 2 to vibrate, such as an eccentric block vibrator or an electromagnetic vibrator; the vibration table 11 is the component that holds the test mold 2, such as a plate structure or a table structure, but not limited to these. The test mold 2 can be a cubic test mold 2, or a cylindrical test mold 2, but not limited to these. The support frame 3 is the component used to raise and install the injection mechanism 4, such as a bent arm structure, or a structure with multiple support rods and a plate at the top, but not limited to these. The injection mechanism 4 is the component that can automatically inject concrete into the test mold 2, such as by using the weight of the concrete in conjunction with a switch, or by using a screw conveyor, pump (using a hydraulic or electric pump in conjunction with a pipeline), etc., but not limited to these. The lifting and lowering of the injection mechanism 4 can be achieved through the sliding engagement of a slide rail, or by directly using a cylinder-driven lifting or belt-driven lifting, etc., but not limited to these.
[0034] With this setup, after placing the mold 2 on the vibration table 11, the injection mechanism 4 is lowered and aligned with the mold 2. Concrete is then automatically injected into the mold 2 via the injection mechanism 4, achieving automatic injection. The vibration mechanism 1 then vibrates to eliminate air bubbles in the concrete within the mold 2, improving the strength of the concrete sample after molding. Finally, the injection mechanism 4 rises, removing the mold 2 from the vibration table 11, allowing it to solidify and set.
[0035] In some embodiments, reference Figure 1 The concrete sample preparation device also includes a worktable 5, with a vibration mechanism 1 and a support frame 3 all mounted on the worktable 5. It is understood that the worktable 5 is a component designed to raise the overall height of the concrete sample preparation device; it can be, for example, a box structure or a table structure, but is not limited to these. This facilitates manual operation.
[0036] In some embodiments, the vibration mechanism 1 further includes a vibration drive 12 disposed on the worktable 5, the output end of which is connected to the vibration table 11. Here, the vibration drive 12 may be a vibration motor or a cylinder-driven vibration, but is not limited thereto. Thus, by driving the vibration table 11 to vibrate through the vibration drive 12, the test mold 2 can be vibrated.
[0037] In some embodiments, reference Figure 1 and Figure 4 The test mold 2 includes a bottom mold 21 placed on a vibration table 11, and a forming mold 22 placed on the bottom mold 21. The forming mold 22 has at least one through groove 221. It is understood that the through groove 221 is a structure for storing concrete, and can be a cubic or cylindrical structure, etc. Thus, after the concrete is formed, the bottom mold 21 and the forming mold 22 can be separated, and the formed sample can be knocked out from the through groove 221, facilitating demolding.
[0038] Furthermore, the bottom mold 21 is provided with a limiting part 211 on its top to limit the horizontal position of the forming mold 22. It is understood that the limiting part 211 can be a groove structure that fits into the forming mold 22, or a limiting block structure that limits the outer edge of the bottom of the forming mold 22, but is not limited to these. Thus, when the vibration mechanism 1 vibrates, the forming mold 22 and the bottom mold 21 will not move relative to each other, ensuring that concrete does not leak out.
[0039] Preferably, refer to Figure 1-2 The injection mechanism 4 includes: a fixed frame 41, a hopper 42, and a flow switch. The fixed frame 41 is vertically mounted on the base plate 31; the hopper 42 is mounted on the fixed frame 41 and is used to store concrete; the bottom of the hopper 42 is provided with nozzles 421 that correspond one-to-one with the through grooves 221; the flow switch is mounted on the nozzles 421 and is used to control the flow rate of concrete sprayed from the nozzles 421.
[0040] Understandably, the mounting bracket 41 is a component for mounting the container 42. For example, it can be a plate structure (with mounting holes in the plate to embed the container 42), or a structure composed of multiple plates and connecting rods, but is not limited to these. The container 42 is a component for storing concrete, and can be a tank structure or a square silo structure, but is not limited to these. The flow switch can be a mechanical flow switch (turbine or piston type), or an electromagnetic flow switch, but is not limited to these. The mating structure between the flow switch and the nozzle is prior art and is not shown in the accompanying drawings.
[0041] With this setup, once the test mold 2 is placed on the vibration table 11, the fixing frame 41 moves downward, causing the container 42 to move downward as well. This allows the nozzle 421 to enter the test mold 2, and the flow switch opens the spray nozzle, automatically injecting the concrete from the container 42 into the test mold 2. The injection volume can be controlled by adjusting the opening time of the flow switch.
[0042] In some embodiments, the injection mechanism 4 further includes a telescopic drive member 43 disposed on the substrate 31, the output end of which is connected to the fixed frame 41. It is understood that the telescopic drive member 43 may be a cylinder or an electric push rod, but is not limited thereto. Thus, the telescopic drive member 43 can drive the fixed frame 41 to rise and fall, thereby driving the container 42 to rise and fall.
[0043] In some embodiments, a baffle plate 6 is provided at the bottom of the fixing frame 41, located above the nozzle 421. The baffle plate 6 is used to press against the top of the mold 2 and close the through groove 221 during the downward movement. Here, the baffle plate 6 can be a plate structure that presses directly against the top of the mold 2, or it can be a plug-type structure, that is, embedded in the through groove 221 of the mold 2. In this way, after the fixing frame 41 moves downward, the baffle plate 6 presses against the top of the mold 2 and closes the mold 2, which can prevent concrete from splashing out. It can also prevent the forming mold 22 from coming out of the bottom mold 21 due to vibration.
[0044] In some embodiments, reference Figure 5 The top of the storage silo 42 is connected to an extrusion mechanism 8 via a pipe 7. The extrusion mechanism 8 is used to store concrete and extrude concrete into the storage silo 42. It is understood that the extrusion mechanism 8 can be a component that works in conjunction with a pumping mechanism, or it can be a small concrete pump truck, etc., but is not limited to these. The pipe 7 is used to connect the extrusion mechanism 8 and the storage silo 42. Considering that the storage silo 42 needs to be raised and lowered, the pipe 7 can be made of a flexible gel tube, or a spiral-type telescopic pipe structure, but is not limited to these.
[0045] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
