Before detecting different raw materials, first pour the raw materials into the corresponding conical feeding chutes 202 in sequence, so that the raw materials can fall through the corresponding feeding pipes 4;

[0033] In an embodiment of the present invention, further, a plurality of telescopic sealing plates 6 are slidably inserted into the hopper 2 for blocking between the corresponding conical feeding grooves 202 and the feeding pipes 4. A telescopic bellows 7 is fixed between the telescopic sealing plate 6 and the machine body 1, and a communicating air pipe 8 is connected between adjacent telescopic bellows 7. A pump 3 is installed inside the machine body 1, and the air outlet end of the pump 3 is connected to the telescopic bellows 7 through the communicating air pipe 8 for driving the plurality of telescopic sealing plates 6 to slide outwards in sequence, so that the raw materials inside the plurality of conical feeding grooves 202 are discharged through the feeding pipes 4 in sequence. The pump 3 is an existing device for performing gas pressurization operations, which will not be elaborated here. As the pump 3 operates, gas is conveyed into the communicating air pipe 8, causing the corresponding telescopic bellows 7 to expand under pressure, and the corresponding telescopic sealing plate 6 to slide outwards. At this time, as the telescopic sealing plate 6 slides outwards, the conical feeding groove 202 and the feeding pipe 4 can be connected, enabling the raw materials inside the conical feeding groove 202 to be discharged through the corresponding feeding pipe 4. As the pump 3 continuously conveys gas into the communicating air pipe 8, the gas can enter the adjacent telescopic bellows 7 through the communicating air pipe 8, causing the adjacent telescopic sealing plates 6 to slide outwards, realizing that the adjacent conical feeding grooves 202 and the feeding pipes 4 can be connected in sequence, and enabling the raw materials inside the conical feeding grooves 202 to be fed in sequence;

[0034] In an embodiment of the present invention, specifically, a support spring 601 is fixedly installed between the telescopic sealing plate 6 and the machine body 1 for driving the telescopic sealing plate 6 to reset.

[0036] In an embodiment of the present invention, specifically, a vibration motor 501 is fixedly installed at the bottom of the discharging rack 5, which is used to be turned on when the discharging rack 5 is discharging, so that when the discharging rack 5 vibrates, it drives the multiple sections of feeding pipes 4 to vibrate.

Detection test tubes 14 are inserted into the limiting frames 13 respectively. The drive shaft 11 is used to drive the load-bearing disk 12 and the detection test tubes 14 to rotate, so that the raw materials discharged through the feeding pipe 4 fall into the detection test tubes 14. A motor is installed at the bottom of the machine body 1, which is not shown in the figure, and is used to drive the drive shaft 11 to operate. As the drive shaft 11 operates, it can drive the load-bearing disk 12 and a plurality of limiting frames 13 to operate, so that the detection test tubes 14 inside the limiting frames 13 pass through the discharging rack 5 in sequence, and the raw materials inside the discharging rack 5 fall into the corresponding detection test tubes 14 in sequence;

[0040] In the embodiments of the present invention, further, a liquid storage tank 10 is fixed inside the machine body 1, and a liquid discharge pipe 1001 is fixedly installed at the bottom of the liquid storage tank 10, which is used to inject liquid into the detection test tubes 14.

When the load-bearing plate 12 operates, it can drive a plurality of transmission shafts 15 to operate, so that the transmission shafts 15 can drive the transmission gears 1501 sleeved outside along the transmission tooth rack 1202. At this time, the transmission shafts 15 can rotate through the cooperation of the transmission gears 1501 and the transmission tooth rack 1202, thereby driving the transmission gasket 1503 fixed at the end of the transmission shaft 15 to operate. By the rotation of the transmission gasket 1503, the test tube 14 can be driven to rotate inside the limit frame 13, realizing the mixing process of the raw materials and the liquid. At the same time, the transmission gasket 1503 is slidably connected inside the limit frame 13. A transmission lifting frame 18 is provided inside the transmission ring 1201. The transmission lifting frame 18 is used to contact the transmission shaft 15 and push the transmission shaft 15 upward.
