[0002] With the development of intelligent manufacturing in the metallurgical industry, among which the temperature measurement and sampling device has rapidly advanced from the original manual installation and disassembly of the probe to the direction of unmanned installation and disassembly of the probe. At present, some steel enterprises have implemented the transformation of automatic installation and disassembly of the probe at each work station (hot metal ladle tipping, hot metal pretreatment, converter, behind the converter, LF, RH, etc.). However, the subsequent extraction of the probe sample and pneumatic sample sending almost all rely on manual operations, and these operations include: taking out the sample in the probe, removing the shell, cooling, cutting the head, checking the qualification, and treating the waste, etc. The manual operation working environment is harsh, the repetitive labor load of workers is large, the safety risk is high, and the operation efficiency is low and the time cycle is long. Summary of the Invention

[0003] In order to overcome the defects of the prior art and provide a detection means with high automation degree, safety and reliability, the present invention discloses an automatic extraction device for probe samples and its usage method.

[0006] The separation box is arranged directly below the fixture, the non-metal recycling box is arranged below one side of the separation box, the screening and shaping box is arranged directly below the separation box, a vibrating screen is arranged in the screening and shaping box, the input end of the first conveyor belt is arranged directly below the sample outlet of the screening and shaping box, a water cooler, a sorting device and a position corrector are successively arranged on the first conveyor belt starting from the input end, a baffle, a cutter and a guide rod are successively arranged at the output end of the first conveyor belt, a waste water tank is arranged below the first conveyor belt, the input end of the second conveyor belt is arranged directly below the outlet end of the guide rod, a weighing device and a second sorting device are respectively arranged at the lower part and the upper part of the second conveyor belt, a metal waste box is arranged below the first conveyor belt and the second conveyor belt, a pneumatic conveyor is arranged at the output end of the second conveyor belt, and the telescopic ejector rod, the first conveyor belt, the cutter, the second conveyor belt, the weighing device and the pneumatic conveyor are all connected to the controller through signal lines.

[0007] The described automatic extraction device for probe samples is characterized in that: the telescopic ejector rod is selected from a hydraulic cylinder or an electric cylinder, and the controller is selected from a microcomputer, a single-chip microcomputer or a programmable controller.

[0008] The usage method of the described automatic probe sample extraction device is characterized by the following steps carried out in sequence:

[0009] ① Separation: The clamp holds the probe with the sample, the telescopic ejector rod extends to cut off the head of the probe with the sample, and the cut-off head is intercepted as the sample for subsequent processing. The sample includes a metal part and a non-metal part. The metal part of the sample includes a body, a sample shell, and a sample shell clamp. The non-metal part of the sample includes the sample head refractory and the cylinder body. Subsequently, the telescopic ejector rod retracts, and the sample drops into the separation box.

The body of the sample has a handle part. After the body of the sample is corrected by the position corrector to have the same orientation of the handle part, it is adjusted by the blocking and deflecting piece to make the handle part face forward. Subsequently, the cutter cuts off the handle part of the sample body;

[0011] ③ Weighing: The sample body with the handle part cut off drops onto the second conveyor belt. The sample body with the handle part cut off is first weighed by the weighing device on the second conveyor belt.

If the weight is qualified, the weighing device sends a qualified signal, and the second conveyor belt transports the sample body with the handle part cut off to the output end. The pneumatic conveyor starts to transport the qualified sample body with the handle part cut off to the next process.

[0012] The usage method of the described automatic probe sample extraction device is characterized in that in step ②, the body, the sample shell, and the sample shell clamp of the sample are all cooled by the water cooler to no higher than 50 °C.

The non-metal part of the sample 200 falls into the non-metal recycling bin 31, and the metal part of the sample 200 falls into the screening and shaping box 22. Inside the screening and shaping box 22, the metal part of the sample 200 is vibrated and screened to separate the sample body, the sample shell, and the sample shell clamp;

[0022] ② Conveyance: The body, the sample shell, and the sample shell clamp of the sample 200 all fall onto the first conveyor belt 41.
