[0017] (3) The invention, after the push plate moves to the top, will move along the top of the cross bar toward the direction of the electric push rod, so that the push plate does not contact the baffle when moving toward the direction of the electric push rod, to prevent the push plate from scraping the material off the baffle, resulting in part of the medicine being unable to flow to the bottom and being retained for a long time, resulting in loss of medicinal properties, thus avoiding waste and saving costs. The baffle will block the medicine at a fixed time by rotating, to prevent excessive medicine from entering at one time, which will cause accumulation inside the feed pipe and make the device unable to complete the unloading smoothly, thus ensuring the continuity of the device.
