Agricultural seed sun-drying device capable of removing dust and chips

Abstract

The invention relates to the technical field of agriculture, in particular to an agricultural seed sun-drying device capable of removing dust and chips. The device comprises a rack. A screening cavityis formed in the rack, a movable groove is formed in the screening cavity, a primary screening net plate is mounted in the movable groove, a discharge port is formed in the side edge of the screeningcavity, a screening frame is arranged on the side edge of the discharge port, a discharge frame is arranged on the screening frame, an inner cavity of the discharge frame is divided into multiple guide grooves, a secondary screening net plate is arranged at the bottoms of the guide grooves, an airflow frame is arranged at the bottom of the rack, an air conveying pump is mounted on the airflow frame, an air conveying pipe is mounted at the air conveying end of the air conveying pump, the top of the air conveying pipe stretches above the discharge frame and is divided into multiple branch air pipes, the branch air pipes correspond to the guide grooves one to one, air sprayers are mounted at the bottoms of the branch air pipes, and the air sprayers are located above the inclined portions ofthe guide grooves. After seeds are sun-dried, leaf chips, shriveled seeds, dust and other impurities with low mass can be blown away, and therefore the collecting quality of the seeds is improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an agricultural seed drying device capable of removing dust and debris. Background technique [0002] Gymnosperms and angiosperms are unique propagules, which are formed by pollination and fertilization of ovules. Seeds are generally composed of three parts: seed coat, embryo and endosperm. Some mature seeds of plants only have two parts: seed coat and embryo. Seed formation enables young sporophytic ovules to be protected by the mother and nourished like a mammalian fetus. Seeds also have various structures suitable for spreading or resisting unfavorable conditions, creating favorable conditions for the continuation of the plant race. Before planting in agriculture, the harvested seeds need to be dried in the sun and then planted in the next year. However, dust and leaf debris in many environments often fly into the sun when the seeds are dried. Such environmental foreig...

AI Technical Summary

Problems solved by technology

Before sowing in agriculture, the harvested seeds need to be dried in the sun and then sowed in the next year. However, dust and leaf debris in many environments often fly into the sun when the seeds are dried. Such environmental foreign objects will be mixed in the seeds and affect subsequent sowing.

[0003] Chinese patent (authorized announcement number: CN109059452A) discloses a multi-directional flipping agricultural seed drying device, which enables the device to realize multi-directional flipping of seeds, makes the seeds evenly dried, and can effectively improve the effect of drying seeds and the efficiency of drying seeds , but there are also the above-mentioned defects, which cannot effectively remove dust and blade debris in the environment, which is a problem that needs to be optimized in existing agricultural technology
