[0027] Connection method: A rotating telescopic auxiliary cleaning device is mainly used to assist the cleaning of medicinal material cleaning machine 16 to clean medicinal materials, and is located at the bottom of the tank of the medicinal material cleaning machine 16. The cleaning device body 1 is a hollow cylinder, and a cylindrical hollow air inlet pipe 14 is provided on the left side. The bottom of the cleaning device body 1 is locked and connected with the lower head 11 of the main body through a chuck 7. A sealing gasket 8 is provided between the cleaning device body 1 and the lower head 11 of the main body to increase the air tightness of the auxiliary cleaning device 15. A spring upper pad 9 with a trapezoidal through hole is fixedly installed between the cleaning device body 1 and the lower head 11 of the main body. The cleaning device body 1 and the lower head of the main body are connected. A coaxial main shaft 6 is provided inside the main body 11, and the upper end of the main shaft 6 is a sealing disk 63 with a rectangular groove. The main shaft 6 passes through the cleaning device body 1 and the lower head 11 of the main body. The sealing disk 63 at the upper end of the main shaft 6 is connected with the upper gap of the cleaning device body 1, and the gap between the cleaning device body 1 and the main shaft 6 is sealed by a sealing ring 2 embedded in the rectangular groove of the sealing disk 63 at the upper end of the main shaft 6. A cleaning spray head 3 is provided below the sealing disk 63 at the upper end of the main shaft 6. The cleaning spray head 3 is a cylindrical hollow structure and is installed and connected to the main shaft 6 by interference fit. The cleaning spray head 3 is provided with a circular ring seal outside. A sealing ring 2 is provided below the cleaning spray head 3, and a spray head lower supporting block 4 is provided below the cleaning spray head 3. The spray head lower supporting block 4 is nested and connected with the cleaning spray head 3 and presses against the lower end of the cleaning spray head 3. A circular ring sealing ring 2 is provided outside the spray head lower supporting block 4, and a retaining spring 5 clamped on the retaining spring groove 62 is provided below the spray head lower supporting block 4. The retaining spring 5 presses against the spray head lower supporting block 4 to prevent the spray head lower supporting block 4 and the cleaning spray head 3 from sliding relative to the main shaft 6 during movement, thereby playing a limiting role. The main shaft 6 passes through the trapezoidal through hole of the spring upper pad 9 to the lower inner part of the main body lower head 11. The main shaft 6 is provided with a retaining spring 5 above the spring upper pad 9 to limit The main shaft 6 continues to move downward, and a spring 10 is arranged inside the trapezoidal through hole of the spring upper pad 9. The spring 10 is nested in the lower end part of the main shaft 6. A spring lower washer 12 with a through hole is arranged below the spring 10 to push the spring up and down. A locking block 13 is arranged below the spring lower washer 12. The locking block 13 is a trapezoidal through hole structure. The large end of the locking block 13 is tightly pressed against the upper end surface of the end nut 61 at the lower end of the main shaft 6. The upper end of the end nut 61 is a threaded structure, which is tightened in the threaded hole at the lower end of the main shaft. The upper part of the end nut 61 is pressed against the bottom of the locking block 13 and prevents the spring lower washer 12 from continuing to move downward.

[0028] Working principle: The auxiliary cleaning device 15 is located at the lower end of the medicinal material cleaning machine 16, and assists it in cleaning the medicinal material. First, water and the medicinal material to be cleaned are added to the medicinal material cleaning machine 16, and the medicinal material cleaning machine 16 is started. The motor will drive the stirring blade to rotate at a low speed to turn the medicinal material over for cleaning. Because some medicinal material will be deposited on the sieve plate at the bottom of the tank during the cleaning process, compressed gas is introduced into the cylindrical hollow air inlet pipe 14, and the compressed gas will enter the cleaning device body 1 through the cylindrical hollow air inlet pipe 14. With continuous After the compressed gas is introduced, the air pressure inside the cleaning device body 1 increases to a certain pressure, and the compressed gas will push the sealing disk 63 at the upper end of the main shaft 6 to move. The main shaft 6 overcomes the resistance of the spring 10 and moves upward. The main shaft 6 drives the retaining spring 5, and the retaining spring 5 pushes the lower support block 4 of the spray head and the cleaning spray head 3 to move upward. When the oblique nozzle 31 and the straight nozzle 32 of the cleaning spray head 3 extend to the outside of the cleaning device body 1, the sealing ring 2 on the lower support block 4 of the spray head contacts and seals with the inner wall of the cleaning device body 1, and the compressed gas passes through the circumference inside the lower support block 4 of the spray head. The vent hole 41 reaches the oblique nozzle 31 and the straight nozzle 32 to discharge from the inside of the cleaning device body 1. Since the oblique nozzle 31 is at an angle of 30 degrees to the diameter direction, the cleaning spray head 3 rotates around the main shaft 6 under the reaction of the compressed gas, and the compressed gas also rotates 360 degrees around the main shaft to realize the rotation function, which is conducive to the uniform discharge of the gas. When the compressed gas is discharged from the inside of the cleaning device body 1, the air pressure inside the cleaning device body 1 decreases, and the spring 10 pushes the main shaft 6 again to drive the cleaning spray head 3 and the lower support block 4 of the spray head and the retaining ring 5 to move downward. After the sealing ring 2 on the cleaning spray head 3 seals the cleaning device body 1 again, the air pressure inside the cleaning device body 1 rises again, and the cleaning spray head 3 continuously retracts and rotates around the main shaft 6 and continuously circulates the sealing and exhausting gas movement. The high-frequency repeated movement realizes the rotation of the compressed air and sends it into the bottom of the medicinal material cleaning machine 16 tank, so that the mixture of material and water deposited on the upper part of the gate valve filter plate generates bubbles and forms a stirring effect under the action of the gas, effectively avoiding the medicinal material from being deposited at the bottom of the tank body, thereby improving the cleaning efficiency and cleaning quality.
