[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The clean water can be heated evenly by rotating the rectangular heating rod and the L-shaped stirring rod, which can improve the efficiency of heating the clean water, thereby improving the heating efficiency of Chinese herbal medicines, and thereby improving the detection efficiency of Chinese herbal medicines.

[0014] 2. The movement of the piston ring drives the connecting pipe, the spiral rod, and the short pipe to move, and then drives the rectangular heating rod and the L-shaped stirring rod to move.

[0018] 6.

[0031] The present invention also discloses a method for quality detection of Chinese herbal medicine slices, comprising the following steps: S1, open the upper cover 7 to add Chinese herbal medicine pieces and clean water into the glass tube 2, and then energize the motor 19 and the rectangular heating rod 16; S2, the motor 19 drives the driving shaft 20 and the first gear 21 to rotate, the first gear 21 rotates to drive the second gear 22 to rotate, the second gear 22 rotates to drive the vertical tube 8 and the rectangular tube 9 to rotate, the rectangular tube 9 rotates to drive the plurality of first piston cylinders 10, the plurality of rectangular heating rods 16 and the plurality of L-shaped stirring rods 17 to rotate, and the clean water can be heated by the rotation of the rectangular heating rods 16 and the L-shaped stirring rods 17; S3, after being soaked in clean water and stirred by the rectangular heating rod 16 and the L-shaped stirring rod 17, the Chinese herbal medicine pieces can be driven to move with the clean water, and the Chinese herbal medicine pieces are observed to be broken in this process through the glass tube 2 to understand their quality, and the sulfur dioxide and pesticide residues contained in the Chinese herbal medicine pieces can be detected by the sulfur dioxide detector 4 and the pesticide detector 5; S4, the pressure in the glass cylinder 2 increases, which increases the movement amplitude of the connecting rod 32 and the movable piston 31, and the rotation speed of the motor 19 is fixed. In conjunction with the electromagnetic pressure relief valve, the rectangular heating rod 16 and the L-shaped stirring rod 17 can move and rotate at different speeds to achieve speed change, which can accelerate the stirring of the steamed Chinese medicine, so as to understand whether the Chinese medicine pieces are broken after steaming and whether the quality is qualified.

[0032] When the present invention is used, the upper cover 7 is opened to add Chinese herbal medicine pieces and clean water into the glass cylinder 2, and then the motor 19 and the rectangular heating rod 16 are powered on; The motor 19 drives the driving shaft 20 and the first gear 21 to rotate, the first gear 21 rotates to drive the second gear 22 to rotate, the second gear 22 rotates to drive the vertical tube 8 and the rectangular tube 9 to rotate, the rectangular tube 9 rotates to drive the plurality of first piston cylinders 10, the plurality of rectangular heating rods 16 and the plurality of L-shaped stirring rods 17 to rotate, and the clean water can be evenly heated by the rotation of the rectangular heating rods 16 and the L-shaped stirring rods 17, which can improve the efficiency of heating the clean water, and further improve the heating efficiency of the Chinese herbal medicine slices; After being soaked in clean water and stirred by the rectangular heating rod 16 and the L-shaped stirring rod 17, the Chinese herbal medicine pieces can be driven to move with the clean water. If the Chinese herbal medicine pieces are broken in this process, the Chinese herbal medicine pieces such as Poria cocos and Adenophora australis, if there is obvious breakage, it means that the Chinese herbal medicine pieces are of poor quality or even counterfeit; The rotation of the first gear 21 drives the third gear 23 to rotate, the rotation of the third gear 23 drives the rotating tube 25 to rotate, the rotation of the rotating tube 25 drives the circular plate 27 to rotate, the rotation of the circular plate 27 drives the slider 34 to rotate, the process of the slider 34 rotating drives the connecting rod 32 to move, the movement of the connecting rod 32 drives the moving piston 31 to move, when the moving piston 31 moves close to the circular plate 27, it can suck the air in the vertical tube 8, the rectangular cylinder 9 and multiple first piston cylinders 10 into the second piston cylinder 28, the air in the first piston cylinder 10 is reduced, driving the piston ring 11 to move, The movement of the piston ring 11 drives the connecting pipe 13, the spiral rod 14, and the short tube 15 to move, and then drives the rectangular heating rod 16 and the L-shaped stirring rod 17 to move. The spiral rod 14 rotates when moving on the cross bar 12 (the principle is similar to that of a flying fairy toy or a hand-pushed Frisbee); the rotation and movement of the spiral rod 14 drives the short rod 15, the rectangular heating rod 16, and the L-shaped stirring rod 17 to rotate and move, so that the clean water and the Chinese herbal medicine pieces can be heated and stirred in a variable manner, and the Chinese herbal medicine pieces can be prevented from being stuck between the rectangular heating rod 16 and the L-shaped stirring rod 17; When the movable piston 31 moves away from the circular plate 27, the air in the second piston cylinder 28 can be transported to the multiple first piston cylinders 10, so that the piston ring 11 can be driven to reset. As mentioned above, the rotation and movement of the spiral rod 14 drives the short rod 15, the rectangular heating rod 16 and the L-shaped stirring rod 17 to rotate and move in the opposite direction, so that the clean water and the Chinese herbal medicine pieces can be heated and stirred in a variable manner to improve the heating efficiency. Through the form of variable stirring, the quality of the Chinese herbal medicine pieces after immersion can be detected; As the clean water is heated, the Chinese herbal medicine pieces are also heated. The qualified Chinese herbal medicine pieces can be judged according to the color of the water after the qualified Chinese herbal medicine is boiled. If the color is similar, it is considered qualified. On the contrary, it means that the quality of the Chinese herbal medicine pieces is inferior or there is fraud. In this process, the sulfur dioxide detector 4 and the pesticide detector 5 can detect the pesticide residue in the Chinese herbal medicine slices and whether they are fumigated with sulfur by the merchant. The sulfur dioxide detector 4 and the pesticide detector 5 are connected to external devices to know the test results, and then it can be judged whether the pesticide residue is qualified, whether it is fumigated with sulfur by the merchant, and then the safety quality of the Chinese herbal medicine slices can be understood; As the water and Chinese medicine pieces are boiled, the water vapor in the glass tube 2 increases, resulting in an increase in pressure, and the water vapor is discharged through the exhaust pipe 3. The sulfur dioxide can be further detected by the sulfur dioxide detector 4 to more accurately understand whether the Chinese medicine products are smoked with sulfur by the merchants; Part of the water vapor enters the third piston cylinder 33 through the air intake pipe 6 and the second rotary joint 26. The pressure in the third piston cylinder 33 increases and is greater than the elastic force of the spring 38, thereby driving the sealing piston 37 to move. The movement of the sealing piston 37 drives the push rod 36 and the slider 34 to move. In this way, the slider 34 is away from the middle of the circular plate 27. When the slider 34 rotates with the circular plate 27, the radius of the circumference of the slider 34 is increased, thereby driving the connecting rod 32 and the moving piston 31 to move more. In this way, the movement of the moving piston 31 can increase the amount of air inhaled and the amount of air discharged. Since the movement amplitude of the connecting rod 32 and the movable piston 31 increases, and the rotation speed of the motor 19 is fixed, the movement of the movable piston 31 increases the rate of air discharge, and then the air speed entering the first piston cylinder 10 increases, and the movement speed of the piston ring 11 is increased, thereby increasing the movement and rotation speed of the rectangular heating rod 16 and the L-shaped stirring rod 17, and realizing speed change, the boiling Chinese medicine can be accelerated to stir, so as to understand whether the Chinese medicine pieces are broken after boiling and whether the quality is qualified; When the pressure sensor detects the set pressure value, it can transmit a signal to the controller. The controller controls the solenoid valve to open, which can quickly release pressure. After the pressure is released, the sealing piston 37 is reset under the action of the spring 38. When the pressure drives the sealing piston 37 to move, the above is repeated, and the speed of movement and rotation of the rectangular heating rod 16 and the L-shaped stirring rod 17 can be intermittently changed, so that the Chinese herbal medicines can be stirred and detected more effectively.

[0033] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
