Description

Tobacco seed thresher

technical field

The utility model relates to a crop seed threshing machine in agricultural machinery, in particular to a thresher suitable for tiny seeds such as tobacco seeds.

Background technique

Tobacco seeds are very small, generally about 0.6-0.8mm in length, 0.4-0.55mm in width, 1,000-grain weight of 60-100mg, about 12,000-14,000 seeds per gram, and 2,000-4,000 seeds in each capsule. After the capsule matures, the skin is dry, very thin, leathery, and quite tough. The most primitive methods of seed detachment mainly include human impact threshing, rubbing detachment and flails, stone rollers and other methods of beating and rolling, which are very labor-intensive, inefficient and wasteful; there are also corn milling machines and similar machinery converted into tobacco Seed detachment machine, although the detachment effect is obviously accelerated, but it is easy to damage the seed coat of tobacco seeds, or the seeds are broken, which seriously affects the quality of the seeds. At present, the detachment machines used for food crops on the market are generally bulky and rough, and are not suitable for tiny seeds such as tobacco. Even if some can meet the detachment needs, they cannot guarantee the safety of the seeds. Therefore, it is very necessary to invent a kind of machinery suitable for tobacco seed detachment to promote the industrialization of tobacco seeds, improve the quality of seed propagation, and reduce the cost of propagation and production.
