The rotating plate 5071 rotates to adjust the monitored object, and when the rotating plate 5071 rotates, it can drive the third gear 5099 to rotate, and the third gear 5099 is meshed with the tooth plate 50910 at the bottom end of the sliding frame 5081, so that after the rotating plate 5071 rotates, it can drive the sliding frame 5081 to move along the sliding groove 50911, and then adjust the position of the Chinese medicinal materials on the top of the support plate 5085 to avoid the puncture needle 5106 puncturing the Chinese medicinal materials at the same position every time, thereby improving the monitoring accuracy.

[0024] Working principle: When working, first open the control panel 3, evenly place the columnar Chinese medicinal materials that need to be dried on the top of the placement plate 502, and place the columnar Chinese medicinal materials of the same type on the supporting plate 5085 corresponding to the placement plate 502. Different columnar Chinese medicinal materials can be dried on each placement plate 502 respectively. Place the columnar Chinese medicinal materials on the supporting plate 5085 and make the Chinese medicinal materials contact with the back plate 5084. Then turn on the first motor 5089 to rotate the double-headed screw 5088, thereby driving the two limiting plates 5087 to approach each other, thereby limiting the columnar Chinese medicinal materials. Then turn on the second motor 50811 to rotate the rotating screw 50810, thereby driving The support plate 5085 moves toward the rotating plate 5071. During installation, the support plate 5085 needs to be moved to the following position: after the rotating plate 5071 rotates, the support plate 5072 faces the support plate 5085, and the end of the support plate 5072 is in close contact with the outer wall of the columnar Chinese medicinal materials, and the second contact point 5102 is in contact with the first contact point 5101. After placement, since Chinese medicinal materials are placed on the placement plate 502, the placement plate 502 moves downward, and the connecting pressing plate 506 moves toward the supporting plate 5072, so that the connecting pressing plate 506 is in contact with the end of the supporting plate 5072. Then, the box door 2 is closed, and the baking equipment inside the drying box 1 is turned on to dry the Chinese medicinal materials. As the Chinese medicinal materials are dried, the moisture of the Chinese medicinal materials on the top of the placement plate 502 is discharged, so that the weight of the Chinese medicinal materials on the top of the placement plate 502 is reduced, and the support plate 5072 supports the connecting pressure plate 506. The placement plate 502 generates pressure on the support plate 5072, so that the compression spring 5076 is compressed, and one end of the compression spring 5076 is pressed on the pressure sensor 5077. The pressure sensor 5077 can monitor the amount of moisture discharged from the Chinese medicinal materials on the placement plate 502, so as to facilitate the monitoring of the drying status; At the same time, when the drying state of the Chinese medicinal materials is detected, the third motor 5094 is turned on to rotate the second gear 5093 half a circle. Since the second gear 5093 is meshed with the first gear 5092, the rotating plate 5071 is driven to rotate half a circle, so that the support plate 5072 is directed toward the Chinese medicinal materials on the support plate 5085, so that the support plate 5072 and the Chinese medicinal materials are closely attached, and the first contact point 5101 is in contact with the second contact point 5102, so that the electromagnet 5109 is energized to repel the magnetic block 5108. The force causes the puncture needle 5106 to move outward and penetrate into the Chinese medicinal material. In the original state, the two ends of the conductive rod 51010 on the inner plate 5105 are respectively in contact with the two third contacts 51011. When the puncture needle 5106 completely penetrates into the Chinese medicinal material, the two ends of the conductive rod 51010 are respectively in contact with the two fourth contacts 51012, thereby obtaining the time for the puncture needle 5106 to penetrate into the Chinese medicinal material. When the water content of the Chinese medicinal material is low, the density of the Chinese medicinal material is high, which makes the puncture needle 5106 penetrate slower. At the same time, when the water content of the Chinese medicinal materials decreases, the Chinese medicinal materials will shrink. After the rotating plate 5071 rotates, the first contact 5101 cannot contact the second contact 5102, and the pressure of the pressure sensor 5077 has not reached the maximum value. It can be judged whether the first contact 5101 and the second contact 5102 are in contact according to the pressure of the pressure sensor 5077. If not, the second motor 50811 is turned on to make the support plate 5085 continue to move toward the rotating plate 5071 until the first contact 5101 and the second contact 5102 are in contact. After the monitoring of the Chinese medicinal materials themselves is completed, the rotating plate 5071 is driven by the third motor 5094 to continue to rotate until the support plate 5072 is in contact with the connecting pressure plate 506, so as to continue to monitor the gravity of the Chinese medicinal materials above the placement plate 502. During the rotation process, the third gear 5099 can be driven to rotate by the first sprocket 5095, the second sprocket 5096 and the chain 5097, and the third gear 5099 is engaged with the tooth plate 50910. After the rotating plate 5071 rotates, the sliding frame 5081 is driven to move along the sliding groove 50911, thereby driving the support plate 5085 to move, so that when the support plate 5072 contacts the Chinese medicinal materials above the support plate 5085 again, the contact position changes, thereby preventing the puncture needle 5106 from being inserted into the Chinese medicinal materials from the previous hole, thereby improving the detection accuracy.
