In addition, the positioning sleeve 21 is provided with a positioning portion 22 to further quickly fix the bearing 23, which facilitates assembly and disassembly, and is provided with a first fan 24 to cool the drive shaft 9 and reduce the temperature in the drying box 7 The influence of the motor 11 extends the service life of the device.

[0019] The lower left end of the drying box 7 is provided with a blowing port 15, the blowing port 15 is provided with a second fan 14, and the upper end of the drying box 7 is provided with an exhaust port 18, and the exhaust port 18 is provided with a circulation Pipe 17, the other end of the circulation pipe 17 is provided with a moisture and dust purification box 16, the lower end of the moisture and dust purification box 16 is connected to the second fan 14 through the pipe, the circulation pipe 17 is arranged so that the inside of the drying box 7 Heat can be recycled, reducing heat loss, energy saving and environmental protection. Several temperature sensors 20 and heating plates 19 are arranged inside the drying box 7, and a slag discharge pipe 13 is arranged at the lower end of the drying box 7. An observation window 39 is provided in the middle of the front side of the box 7, the moisture and dust purification box 16 includes a box body, a moisture filter and a dust filter are arranged inside the box, and a soundproof cover is arranged on the outside of the motor 11, The lower side of the base 1 is provided with a shock-absorbing pad, the drying box 7 is provided with a controller that controls the operation of the device, and the screen mesh drum 8 is set. When drying, the screen mesh drum 8 rotates, and at the same time , By turning on and off the electromagnet 4 to make the screen cylinder 8 move up and down, so that the medicine slag enters the drying box 7, so that the number of Chinese medicine pieces and dust in the dried Chinese medicine pieces is reduced, and the drying is improved. After the appearance quality of Chinese herbal medicine pieces.
