The dust separation device for dried lily bulbs according to claim 6, characterized in that: Belt pressing rods (235) are symmetrically arranged on both sides of the top of the belt wheel (234) located on the output shaft of the double-headed motor (310), and a pair of belt pressing rods (235) clamp the bottom of the transmission belt (231) in a U-shape.

8. The dust separation device for dried lily bulbs according to claim 7, characterized in that: Powder gathering plates (111) are welded to the left and right inner walls of the middle layer of the material storage box (110); the powder gathering plates (111) are inclined and their upper ends are welded to the inner wall of the material storage box (110); a pair of mutually meshing crushing rollers (120) are arranged on the frame (100) and between the pair of powder gathering plates (111); a transmission gear (121) is sleeved on the front end of the central axis of the crushing roller (120); a driving gear (320) is sleeved on the front end output shaft of the double-headed motor (310); and the driving gear (320) is meshed with the pair of transmission gears (121).

9. The dust separation device for dried lily bulbs according to claim 8, characterized in that: The front end top surface of the frame (100) is fixedly connected to a support plate (130), the double-headed motor (310) is fixedly connected to the top surface of the support plate (130) by bolts, and a pair of belt pressing rods (235) are fixedly connected to the top surface of the support plate (130) by bolts.

10. A dust separation method for processing dried lily of the valley, using the dust separation device for processing dried lily of the valley as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1, firstly put the assembled separation box (210) and the screening group (220) into the material storage box (110), and then pour the fried dried lily bulbs onto the screening group (221); S2, then close a pair of movable covers (214) to seal the top port of the separation box (210); S3, starting the double-headed motor (310) to drive the transmission belt (231) to circulate, thereby driving the pair of transmission shafts (232) to rotate, thereby driving the plurality of cams (233) to rotate and push the pair of hanging cloth plates (222) to move up and down, thereby driving the sieve distribution (221) to move up and down with the stems of lily of the valley, causing the crushed stems of lily of the valley to fall from the gap until they leak out from the plurality of powder leaking pieces (224); S4. When the double-headed motor (310) is started, the driving gear (320) is driven to rotate, and the pair of crushing rollers (120) are driven to rotate and mesh, thereby crushing the crushed dried lily bulbs falling from the bottom port of the material storage box (110) again, and then the box is placed under the frame (100) for collection.
