A connecting rod 5 is fixedly connected to the left side of the nozzle 4. A fixing frame 6 is fixedly connected to the top and bottom of the connecting rod 5. A heating pipe 7 is fixedly connected to the inner wall of the fixing frame 6. A motor 8 is fixedly connected to the central axis at the front right side of the housing 1. A lead screw 9 is fixedly connected to the output end of the motor 8. The surface of the lead screw 9 is threadedly connected to the connecting rod 5. An electric telescopic rod 11 is fixedly connected to the central axis at the top of the housing 1. A connecting plate 12 is fixedly connected to the bottom of the electric telescopic rod 11.

A temperature sensor 19 is fixedly connected to the bottom of the left side of the inner cavity of the housing 1.

[0022] The above technical solution involves setting the highest and lowest temperature and pressure values ​​using a PLC controller 18. During high-temperature testing, concrete is placed at the bottom of the inner cavity of the housing 1, and the movable door is closed. Simultaneously, the PLC controller 18 controls the motor 8 to operate, which in turn drives the lead screw 9 to rotate. The lead screw 9 then moves the connecting rod 5, which in turn moves the fixing frame 6. The fixing frame 6 then moves the heating tube 7, ensuring uniform heat distribution. When the temperature sensor 19 detects that the temperature value matches the set highest temperature value, the PLC controller 18 activates the buzzer 17 to sound an alarm. The heating tube 7 is then returned to its original position. The electric telescopic rod 11 and pressure sensor 15 are then activated. The electric telescopic rod 11 moves the connecting plate 12, which in turn moves the connecting plate... 12 drives the elastic telescopic rod 13 to move, the elastic telescopic rod 13 drives the adjusting plate 14 to move, the adjusting plate 14 drives the pressure sensor 15 to move, and the pressure sensor 15 drives the pressure plate 16 to move, squeezing the concrete. After the pressure sensor 15 detects that the pressure value is the same as the set value, the pressure plate 16 is returned to its original position, and then the concrete is observed to see if it is damaged. If it is not damaged, the PLC controller 18 controls the refrigerator 2 to work, and the cooled gas is discharged into the inner cavity of the shell 1 through the bellows 3 and the nozzle 4. After the temperature sensor 19 detects that the temperature value is the same as the set minimum temperature value, the PLC controller 18 controls the electric telescopic rod 11 and the pressure sensor 15 to work again to detect the hardness of the concrete again, so as to make the detection accurate.

[0023] The left side of the lead screw 9 is movably connected to the housing 1 via a bearing, and a through hole is provided at the bottom right side of the housing 1.

[0031] The working principle of this utility model is as follows: The PLC controller 18 sets the highest temperature, lowest temperature, and pressure values. During high-temperature detection, concrete is placed at the bottom of the inner cavity of the housing 1, and then the movable door is closed. Simultaneously, the PLC controller 18 controls the motor 8 to operate, which drives the lead screw 9 to rotate. The lead screw 9 drives the connecting rod 5 to move, the connecting rod 5 drives the fixing frame 6 to move, and the fixing frame 6 drives the heating tube 7 to move, ensuring uniform heat distribution. After the temperature sensor 19 detects that the temperature value is the same as the set highest temperature value, the PLC controller 18 controls the buzzer 17 to sound an alarm. Then, the heating tube 7 is returned to its original position, and the electric telescopic rod 11 and pressure sensor 15 are controlled to operate. The electric telescopic rod 11 drives the connecting plate 12 to move, connecting... The connecting plate 12 drives the elastic telescopic rod 13 to move, the elastic telescopic rod 13 drives the adjusting plate 14 to move, the adjusting plate 14 drives the pressure sensor 15 to move, and the pressure sensor 15 drives the pressure plate 16 to move, thus squeezing the concrete.
