Description

Technical Field

[0001] The present invention belongs to the technical field of lightwood seed fuzz removal and separation, and particularly relates to a seed fuzz remover for lightwood improved variety breeding. Background Art

[0002] Cotton is a seed fiber, that is, the fiber is developed from the seed epidermis and is not separated in the natural state; while the seeds of Ochroma pyramidale in the Bombacaceae family are pericarp fibers. After the seeds mature, they are in a separated state from the pericarp and fibers, and each bundle of fibers carries one seed. However, due to the large number and small size of the seeds, and the light, thin, and soft fibers, the fibers and seeds are mixed together.

[0003] The seed propagation of Ochroma pyramidale is the main way of artificial propagation of Ochroma pyramidale. Its fibers are also commercially known as grass duck down or rabbit claws and are used as fillers for mattresses and cushions, with high utilization value. After the fruits of Ochroma pyramidale are harvested and exposed to the sun, a mixture of Ochroma pyramidale fibers and seeds is formed. The fuzz removal of Ochroma pyramidale seeds is a seasonal and heavy labor. For many years, hundreds of thousands of farmers have used simple tools for manual fuzz removal, which is not only inefficient but also a very tiring job. The following problems exist in the fuzz removal process: when the fuzz removal rate of Ochroma pyramidale seeds is increased, the phenomenon of high breakage rate of Ochroma pyramidale seeds will occur, thus affecting the germination of Ochroma pyramidale seeds; if the breakage rate of Ochroma pyramidale seeds is to be reduced, the fuzz removal rate of Ochroma pyramidale seeds will be affected. Summary of the Invention

[0004] In order to overcome the problems in the background art that manual fuzz removal using simple tools is not only inefficient but also a very tiring job, and the breakage rate of Ochroma pyramidale seeds is high, which affects the germination of Ochroma pyramidale seeds, the present invention provides a seed fuzz remover for lightwood improved variety breeding. By conveying the Ochroma pyramidale seeds with fibers into the fuzz removal device 1, heating and drying the Ochroma pyramidale seeds with fibers through hot air to make them fluffy, and then turning and scattering them by the fuzz removal roller 14, the fibers and seeds are separated, effectively improving the fuzz removal rate and working efficiency. Then, through the air separation device 2 for air separation, the heavier seeds are screened out from the sieve holes under the action of their own gravity, and the lighter fibers are carried out by the air separation air flow, realizing the separation of seeds and fibers; avoiding the seeds from being subjected to a large extrusion force and avoiding the phenomenon of Ochroma pyramidale seed breakage, ensuring the germination rate of Ochroma pyramidale seeds; the collected Ochroma pyramidale seed fibers can be utilized, avoiding the waste of resources formed by burning fuzz removal and acid fuzz removal.
