[0016] 3. By starting the first electric rod to pull the lifting plate to move vertically upward, and drive the slider to move upward, the connecting shell can be driven to move vertically upward, and after the connecting shell is lifted into the inner cavity of the drying cylinder, the connection gap between the connecting shell and the bottom slot is increased, so that the medicinal materials in the inner cavity of the drying cylinder are discharged from the bottom slot, and when the lifting plate moves upward, the square connecting rod can be used to push the L-shaped baffle to move vertically upward, and open the material discharge slot, so that the medicinal materials in the inner cavity of the frame can be discharged downward and collected into the collection box, thereby improving the convenience of collecting medicinal materials.

When the medicinal materials blown out of the inner cavity of the drying cylinder 2 fall into the inner cavity of the frame body 34, the rotating shaft 41 can be driven to drive the second cam 43 to rotate. The second cam 43 rotates to push the push plate 39 to reciprocate up and down, and drives the air-permeable mesh plate 36 to reciprocate up and down, so as to shake the medicinal materials in the inner cavity of the frame body 34 up and down, improving the drying efficiency of the medicinal materials.

[0024] A blanking slot 35 is formed at the bottom of one side of the frame body 34 facing the drying cylinder 2, and an L-shaped baffle 44 is slidably connected to the outer wall of the blanking slot 35.

[0029] Working principle: When the present invention is in use, first, pull the first handle to drive the rectangular cover plate 14 to move horizontally to the left. After opening the feed hopper 13, the medicinal materials can be fed into the inner cavity of the drying cylinder 2 through the feed hopper 13 and the feed pipe 12. After pulling the rectangular cover plate 14 back to reset and resetting the feed hopper 13, start the heating pump 17 to work, and send the hot air into the inner cavity of the drying cylinder 2 through the air inlet pipe 18, so as to dry the medicinal materials. Then, start the second motor 25 to drive the transmission shaft 24 to rotate. The rotation of the transmission shaft 24 drives the scraper 23 to rotate, so as to turn over the medicinal materials. When the scraper 23 rotates to the highest point, start the first motor 42 to drive the rotating shaft 41 to rotate. The rotation of the rotating shaft 41 drives the first cam 40 to rotate. The rotation of the first cam 40 pushes the connecting shell 5 to move vertically upward, so as to push the medicinal materials to turn over upward under the setting of the arc-shaped baffle 6. By working in sequence and cycling, the medicinal materials can be quickly dried. And during the drying process of the medicinal materials, start the two second electric rods 31 to push the two movable plates 30 to move relatively, and drive the two moving racks 29 to move relatively. The movement of the moving rack 29 can drive the rotating gear 28 to rotate, and drive the arc-shaped cover plate 26 to flip through the rotating rod 27, so that after the two arc-shaped cover plates 26 move away from the side slots 3, drive the scraper 23 to rotate to the horizontal state by the second motor 25, and then start the blower 53 on the other side to work, so as to blow the hot air in the inner cavity of the installation box 16 to the drying cylinder 2, and under the setting of the side slots 3, blow the medicinal materials on the scraper 23, and then blow the dried medicinal materials to the outside of the drying cylinder 2 through the side slots 3, and guide them into the inner cavity of the frame body 34 under the setting of the guide plate 56. And when the rotating shaft 41 drives the two second cams 43 on both sides to rotate during the rotation process, and pushes the two breathable mesh plates 36 to vibrate up and down, so as to vibrate the medicinal materials falling on the breathable mesh plates 36, and blow downward through the branch blowing pipe 51, so as to dry the small amount of undried medicinal materials in the inner cavity of the frame body 34 for the second time. And during the drying process, through the setting of the fan 22, the hot air in the inner cavity of the box body 1 can be pumped back into the inner cavity of the installation box 16, and the reflux hot air can be dried under the setting of the dryer 21, so as to realize the circulating heating of the device. When the drying is completed, start the first electric rods 10 on both sides to pull the lifting plate 11 to move vertically upward, so as to pull the connecting shell 5 to move vertically upward under the setting of the two sliders 7. Due to the inclined setting of the side of the connecting shell 5, the gap between the connecting shell 5 and the bottom slot 4 can be increased, so as to discharge the medicinal materials in the inner cavity of the drying cylinder 2 and collect them into the collection box 46. In addition, when the lifting plate 11 moves upward, it can push the L-shaped baffle 44 to move upward through the square connecting rod 45, and open the blanking slot 35, so as to discharge the medicinal materials in the inner cavity of the frame body 34 downward through the blanking slot 35 and collect them into the collection box 46 at the same time. The staff can take out the collection box 46 after opening the sealing door 55 to complete the collection work of the medicinal materials.
