Abstract
The utility model relates to the technical field of powder spreading, and discloses a hygroscopic powder spreading device which is provided with a loading bin, a drying bin and a battery bin from top to bottom, the loading bin at least comprises two branch bins used for storing hygroscopic powder, and the branch bins control feeding through correspondingly-arranged feeders. The drying bin is used for pumping air through an air pump and drying the air through at least one drying unit; the dried air enters a pipeline system, the pipeline system comprises a venturi tube, a throttling valve and an air pressure balance tube, most of the sucked air is conveyed into the venturi tube, the venturi tube conveys moisture absorption powder, and the moisture absorption powder is sprayed out and scattered through a powder spray head; a small part of sucked air enters a hygroscopic powder package through a throttle valve and an air pressure balance pipe to balance the air pressure; the battery bin is used for containing batteries, and the batteries supply power to the charging bin and the drying bin. The device disclosed by the utility model has the advantages of uniform sowing and controllable sowing dosage and position, is not limited to warm cloud catalyst sowing, and is suitable for sowing various powders.
