The baffle 8 can prevent concrete from splashing onto the detection head and affecting the use of the pressure gauge 5. The exhaust pipe 4 can be conveniently opened and closed by the solenoid valve to balance the air pressure inside the device.

[0024] In this embodiment, the four sides of the interior of the support platform 2 are provided with sockets corresponding to one side of the clamping rod 15, and the plugging rod 13 is plugged and installed in the interior of the socket. The shape of the plugging rod 13 and the plugging hole are both square, and an extrusion groove 14 is provided on the side wall of the plugging rod 13. The bottom of the extrusion groove 14 is an inclined surface, and the shape of the clamping rod 15 is "L"-shaped. A spring is fixedly arranged between the top of the clamping rod 15 and the inner side of the inner wall of the bowl body 1, and an extrusion surface is arranged at the bottom of the clamping rod 15. A hydraulic rod 12 is fixedly arranged at the bottom of the clamping rod 15 corresponding to the interior of the bowl body 1, and the output rod of the hydraulic rod 12 contacts the extrusion surface, and the output rod of the hydraulic rod 12 squeezes the clamping rod 15 through the extrusion surface.

At this time, the bottom end of the limit ring 9 is inserted into the interior of the inner tank 7, the hydraulic rod 12 is started, and the output rod of the hydraulic rod 12 squeezes the clamping rod 15 through the extrusion surface, so that the clamping rod 15 slides to one side and compresses the spring, and one end of the clamping rod 15 squeezes the extrusion groove 14 through the inclined surface, and the clamping rod 13 is pressed downward by the action of the clamping rod 15 and the extrusion groove 14, and the clamping rod 13 drives the bowl cover 3 to be tightly installed on the top of the bowl body 1, and the bowl cover 3 is tightly installed on the top of the bowl body 1. A sealing rubber ring 10 and a second sealing rubber ring 11 are used to seal the bowl body 1 and the bowl cover 3, and the bowl body 1 and the bowl cover 3 are fixed without screws, so the operation is simple and convenient. The pressure inside the device is first detected by the pressure gauge 5, and the inner tank 7 is driven to vibrate by the vibrator 6. The inner tank 7 vibrates the concrete, so that the gas inside the concrete (including air, water vapor and other gases) increases the pressure inside the device. The pressure change inside the device is detected by the pressure gauge 5, and the change in the pressure gauge 5 is the air content of the concrete. The baffle 8 is set to prevent the concrete from splashing onto the detection head of the pressure gauge 5 during the vibration process, so as to avoid affecting the detection of the pressure gauge 5. The limit ring 9 is set to block the concrete in the inner tank 7, separate the concrete from the first sealing rubber ring 10 and the second sealing rubber ring 11, and prevent the concrete from corroding the first sealing rubber ring 10 and the second sealing rubber ring 11, so as to ensure the sealing of the device, thereby facilitating the detection of the air content of the concrete, and having high practicality.
