Description

Technical Field

[0001] This utility model relates to the field of seed production equipment technology, and in particular to an integrated machine for seed washing, screening and drying. Background Technology

[0002] Seed selection and cultivation is a crucial part of agricultural planting. After harvesting, seeds need to be washed and floated to remove immature or shriveled seeds, as well as floating impurities such as broken leaves. Common washing tanks can effectively screen impurities and shriveled seeds. However, after washing and screening, seeds need to be dried to prevent mold and germination due to water absorption. This drying process requires discharging the seeds from the washing tank and then placing them in drying equipment. Because the seeds tend to stick to the inner wall of the washing tank after washing, incomplete discharge is possible. Furthermore, discharging seeds from the washing tank and then drying them is time-consuming and labor-intensive, all of which greatly inconvenience the seed drying process. Utility Model Content
