The output end of the electric push rod 505 is connected to the outer wall of the drying cylinder 301 by bolts, and a collection box 506 is arranged below the drying cylinder 301. When the drug extract in the drying cylinder 301 is dried to the expected effect, the drying cylinder 301 is raised until the swing rod 304 on the mounting block 302 reaches the position of the first trigger block 403, and the contact switch 406 at the bottom of the first trigger block 403 is triggered, the heater 602 and the blowing assembly 603 are paused, and the electric push rod 505 pushes the closed bottom plate 504 to open, and the drug extract dried in the drying cylinder 301 falls from the opening of the closed bottom plate 504 into the collection box 506.

[0038] In this embodiment, the inner wall bottom plate of the drying cylinder 301 is set obliquely, the stirring shaft 502 is perpendicular to the inner wall bottom plate of the drying cylinder 301, and a scraper 503 is welded at the bottom of the stirring shaft 502 to prevent the medicine from sticking to the bottom of the drying cylinder 301.

[0039] In this embodiment, the feeding mechanism includes a temporary storage box 203, and an auger-type conveying assembly 204 is fixedly installed on the top inner wall of the mounting shell 102. The temporary storage box 203 leads to the inside of the auger-type conveying assembly 204. A discharge hopper 205 is welded to the discharge end of the auger-type conveying assembly 204. The discharge hopper 205 is arranged directly above the drying cylinder 301. The setting of the auger-type conveying assembly 204 can transport the drug extract containing a certain amount of moisture in the temporary storage box 203 to the discharge hopper 205 position, thereby loading the drying cylinder 301.

[0040] In this embodiment, the working mechanism includes a control switch 601, a heater 602 and a blowing assembly 603. The control switch 601 is connected to the front side of the mounting shell 102 by bolts. The control switch 601 is used to control the power assembly of the auger-type conveying assembly 204. The heater 602 and the blowing assembly 603 are respectively fixedly mounted on both sides of the mounting shell 102.

[0041] Working principle: When the device is in use, the feeding assembly 202 is used to convey the medicine in the material box 201 to the temporary storage box 203 above. The initial position of the drying cylinder 301 is located at the upper position inside the mounting shell 102. When drying starts, the motor 501 in the drying cylinder 301 is turned on and is always in a working state. The motor 501 drives the stirring shaft 502 to rotate. The staff presses the control switch 601 to start the power device of the auger conveying assembly 204. The auger conveying assembly 204 conveys the drug extract in the temporary storage box 203 to the position of the discharge hopper 205. The drug extract containing water falls into the drying cylinder 301. As the drug extract falls, the drying cylinder 30 The tension of the suspension spring 309 increases, and the suspension spring 309 is pulled to move the drying cylinder 301 downward. When the drying cylinder 301 drops to the position of the first lifting block 402, the fixing rod 303 contacts and presses the contact switch 406 on the second trigger block 405. The contact switch 406 controls the auger conveying assembly 204 to stop working, and turns on the heater 602 and the blowing assembly 603. The heater 602 and the blowing assembly 603 dry the drug extract in the drying cylinder 301, and the dried water escapes from the top of the mounting shell 102. While drying, the stirring shaft 502 stirs the drug extract to improve the drying effect. The scraper 503 stirs the bottom of the drying cylinder 301. The wall is scraped to prevent the drug extract from sticking. As the drug extract in the drying cylinder 301 is continuously dried, the pulling force of the drying cylinder 301 on the suspension spring 309 gradually decreases, and the suspension spring 309 pulls the drying cylinder 301 to move slowly upward. When the drying cylinder 301 is lifted to a certain height, the swing rod 304 on the mounting block 302 reaches the position of the first trigger block 403, and the swing rod 304 contacts and presses the contact switch 406 on the first trigger block 403. The contact switch 406 on the first trigger block 403 controls the heater 602 and the blowing component 603 to pause, and at the same time controls the electric push rod 505 to start, open the closed bottom plate 504, and the dried drug in the drying cylinder 301 The drug extract is discharged from the bottom of the drying cylinder 301 and falls into the collecting box 506. During the discharge process, the drying cylinder 301 continues to rise due to the pulling force of the suspension spring 309, and the swing rod 304 is pushed downward by the first trigger block 403 to pass through the first lifting block 402. After passing through the first lifting block 402, the torsion spring 305 resets the swing rod 304, and the staff can open the closed door 103 to take out the dried drug extract in the collecting box 506. The drying cylinder 301 returns to its initial position at the top, and then the staff uses the control switch 601 to close the closed bottom plate 504 at the bottom of the drying cylinder 301, and starts the auger-type conveying assembly 204 to carry out the next step of drying the drug extract.
