Description

Technical Field

[0001] The utility model belongs to the technical field of experimental sample preparation devices, in particular to a casting type experimental sample preparation device. Background Art

[0002] In the field of rock mechanics research, similar simulation tests are often required, that is, model test technology based on similarity theory, which is a method of studying natural laws by using the similarities and similarities between things or phenomena. When using this method for related research, it is necessary to make corresponding similar specimens. The commonly used production methods are mainly pressing and casting. Among them, the former is a molding method that uses pressure to press the powder placed in the mold until the structure is tight, thereby forming a blank with a certain shape and size; the latter is to pour the stirred powder (containing aggregates, binder materials, etc.) into the mold and wait for it to solidify and form. It can be seen that among the two specimen production methods, the specimen production process of the press molding is simple, which is convenient for mechanized large-scale production, and is particularly suitable for flat products with regular geometric shapes. However, influenced by factors such as experimental conditions and research content, in many cases it is necessary to adopt a casting method for preparing specimens. In the actual application of this method, it is first necessary to accurately control the ratio of different raw materials, weigh the aggregates, binders, water and other ingredients, and then fully stir each ingredient (excluding water) to make them evenly mixed; after mixing, add a fixed mass of water and stir it thoroughly; then pour the stirred mixture into a mold and vibrate it with a vibrator to eliminate the bubbles inside, ensure the density and strength of the mixture, and demold and cure it after it solidifies to a certain extent.

[0003] It can be seen from the entire test specimen production process of the above casting that it is necessary to stir the ingredients many times, which is very labor-intensive. Even with a portable mixer and vibrator, it is very difficult to operate. At the same time, when demolding the existing mold, a demolding gun or a detachable mold is generally used. The demolding gun relies on an air source and has a limited scope of application. Non-metallic detachable molds are very easy to deform, and metal detachable molds are very heavy and inconvenient to use. In addition, the production of existing casting-type experimental specimens requires the cooperation of multiple people, resulting in a strong dependence on each step in the specimen production process. If a participant makes a mistake in his work, it will affect the progress and quality of the entire specimen production. Utility Model Content

When the mixed material flows out from the discharge port along the two slurry guide grooves and the inner peripheral wall of the containing groove, the rotary handle is stopped; When the rotary handle is turned to move the lifting rod toward the end of the larger diameter of the truncated table, the lifting rod drives the valve plug to move toward the upper opening end of the mixing barrel, so that the valve plug enters the discharge port to close the discharge port.

4. A casting type test specimen production device as claimed in claim 3, characterized in that: The top surface of the barrel body of the mixing barrel is provided with a first step surface with an L-shaped cross section.

5. A casting type test specimen manufacturing device as claimed in claim 1, characterized in that: The bottom of the cleaning barrel is provided with a slag outlet, a manual slag discharge valve is provided at the slag outlet, and the top surface of the cleaning barrel is provided with a second step surface with an L-shaped cross section.

6. A casting type test specimen manufacturing device as claimed in claim 1, characterized in that: The mixing barrel carrier and the cleaning barrel carrier have the same structure, both including a bearing plate, a plurality of first pulleys, a barrel groove and a plurality of first fixing bolt holes.
