Technical Field

[0001] The utility model relates to the technical field of concrete gas content detection, in particular to concrete gas content detection equipment. Background Art

[0002] Concrete is a mixture of cement, aggregate, water and various admixtures and additives in a certain proportion, which is hardened after a certain period of time to form an artificial stone. During the production and mixing of concrete, more bubbles will be generated. The bubbles are distributed in the fine particles of concrete, namely mortar, and affect the performance of the mortar, thereby determining the performance of the entire concrete. Therefore, it is necessary to detect the air content in concrete.

[0003] In the existing concrete air content test process, it is easy to entrain air in the concrete when the concrete mixture is loaded into the measuring frame. In order to reduce the test error, after the concrete mixture is loaded into the measuring frame, it is necessary to continuously tamp the concrete by manpower, and then use a rubber hammer to hit the outer surface of the measuring frame to reduce the air in the internal concrete mixture. Manual operation is time-consuming and labor-intensive, resulting in low test efficiency. Utility Model Content

[0008] Through the above technical scheme, it is convenient to vibrate the concrete inside the storage frame, reciprocatingly, reduce the bubbles in the concrete, and observe the air pressure of the air pressure detection gauge. By comparing the air pressure data before the detection with the air pressure data after the detection, the air pressure value of the concrete can be obtained, and the limit plate and the middle-shaped block can be reset by the first compression spring to seal the long groove, thereby increasing the accuracy of the measurement value of the concrete container.

[0016] Through the above technical solution, the storage frame can be sealed when the middle-shaped block is inside the long groove.

[0017] Optionally, in the above concrete air content detection device, the front side of the vertical block of the Chinese-shaped block is fixedly connected to a limiting plate, and the rear side of the limiting plate is in contact with the front side of the storage frame.

[0021] In summary, the present invention has at least one of the following beneficial effects:

[0022] Pour concrete into the storage frame, and record the air pressure inside the storage frame with an air pressure detection gauge. Then, the motor drives the cam to rotate, and the cam rotates and contacts the groove, so that the groove drives the slider and the storage frame to move upward. When the smooth side of the cam contacts the groove, the storage frame moves downward, causing the concrete inside the storage frame to vibrate. This process is repeated to reduce bubbles in the concrete, and the air pressure on the air pressure detection gauge is observed. By comparing the air pressure data before and after the test, the air pressure value of the concrete can be obtained.

[0023] The limit plate drives the Chinese-character block to move forward, squeezes the first compression spring, and releases the seal of the long groove. The bottom of the container containing concrete is brought into contact with the rear side of the limit plate, and the container is tilted to pour the concrete into the storage frame. After the concrete is added, the container is taken down, the limit of the limit plate is released, and the limit plate and the Chinese-character block are reset through the first compression spring to seal the long groove, thereby increasing the accuracy of the measurement value of the concrete container.

A cam 302 is fixedly connected to the side of the rotating shaft of the motor 301. The side of the cam 302 contacts the side of the resistance member 9.

[0034] See the attached drawings in the specification Figure 1 , Figure 2 and Figure 3 The sealing member 6 includes a center-shaped block 601, which is slidably connected to the inside of the long groove 5.
