A seed shelling and screening device and its working method

Abstract

The invention relates to a seed shelling and screening device and application thereof. The seed shelling and screening device comprises a bracket, a grinding hammer and a defective material collecting part, wherein a material collecting part, a grinding and shelling part and a screening part are successively and fixedly arranged on the bracket from top to bottom; the hammer body of the grinding hammer is accommodated in the grinding and shelling part; and the defective material collecting part is communicated with the lower half part of the grinding and shelling part. While the device is in use, seeds enter into the grinding and shelling part through the material collecting part, the seeds are shelled through the interaction of the hammer body and the grinding and shelling part, grains enter into the screening part to be screened and separated through sieve cages, and seed shells enter into the defective material collecting part to be processed. The seed shelling and screening device disclosed by the invention is high in shelling efficiency and small in influence on the grains, and realizes the purposes of effectively collecting, grinding and shelling the seeds with shells, and screening and separating the seeds of different particle diameters. According to the device disclosed by the invention, the situation that seed coats and endosperm are not damaged can be ensured, and good quality trait, long preservation life and good sprouting vitality of the shelled seeds are ensured.

Description

technical field [0001] The invention relates to a seed shelling and screening device and its application, belonging to the technical field of crop seed resource collection and processing. Background technique [0002] The shell of crop seeds plays an important role in protecting the germ. However, in the process of collecting, arranging, processing and utilizing crop seeds, it is often necessary to dehull the shelled seeds. Especially for crops such as rapeseed, hemp and beans, shelling is an important process of grain collection and processing, and has an important impact on the physiological activity and product quality of the grain. At present, the removal of crop seed shells is mainly done by manual shelling or using rolling machinery. Manual shelling is inefficient, labor-intensive and time-consuming. Rolling mechanical dehulling often leads to damage to the seed coat and endosperm of the grain, which affects the quality traits, storage life and germination vitality ...

AI Technical Summary

Problems solved by technology

The technical disadvantage of this patent is that the whole volume is huge, which is suitable for the preprocessing of batches of oilseeds. For example, when the equipment is applied to the treatment of bean seeds, the rolling mechanical dehulling often leads to damage to the seed coat and endosperm of the seeds, thus affecting the seeds. quality traits, storage life and germination vigor
