[0022] Working principle: The wormwood is put into the hopper 4 and divided into several portions by the partition plate 7 for uniform cutting. Then the cutting motor 802 is started to drive the connecting shaft 803 to rotate, thereby driving the upper rotary blade 807 and the lower rotary blade 809 to rotate in the opposite direction under the action of the reverse rotation mechanism 808, so as to cut the wormwood quickly and evenly.

The middle conveyor belt 105 and the upper conveyor belt 106 are meshed and connected through the first transmission gear set 108 to ensure that the two run synchronously; Similarly, the mugwort falls from the end of the middle conveyor belt 105 into the lower conveyor belt 103, and is further dried by the lower heat machine 12. The lower conveyor belt 103 and the middle conveyor belt 105 are meshed and connected by a second transmission gear set 109. The conveying motor 110 drives the lower conveyor belt 103 to operate, and drives the upper conveyor belt 106 and the middle conveyor belt 105 to operate synchronously through the transmission action of the chain transmission mechanism 107, the first transmission gear set 108 and the second transmission gear set 109; After multi-stage transmission and deep drying, the wormwood finally falls into the receiving trough 13; The user can adjust the opening size of the discharge pipe 14 by sliding the adjustment plate 15, so as to control the discharge speed and amount of the wormwood.
