Description

Technical Field

[0001] The invention relates to the technical field of seed gravity sorters, in particular to a gravity sorter for breeding leymus chinensis seeds. Background Art

[0002] Leymus chinensis is a native grass in my country. Its seeds are small and irregular in shape. During the harvest period, the stems are green, flexible and easy to entangle. The market has a large demand for leymus chinensis seeds, and the seeds are required to have high purity and quality. The gravity sorting machine can effectively remove impurities such as soil, sand and gravel, broken seed shells, and immature seeds mixed in the seeds according to the density difference between leymus chinensis seeds and impurities, improve the purity of the seeds, and provide high-quality seeds for the planting and promotion of leymus chinensis. Gravity sorting uses the difference in specific gravity between different objects to separate different objects with the help of gravity or centrifugal force.

[0003] Existing gravity sorting machines use lateral blowing to separate low-quality seeds and dust impurities from high-quality seeds during operation. However, with this screening method, since the seeds have inconsistent orientations when falling, the areas of their windward surfaces vary greatly. It is easy for high-quality seeds to be blown out due to excessive force caused by the large windward surface, or for low-quality seeds to be retained due to the small windward surface and small force.

After the material is fed from the middle feed pipe, it falls naturally under the action of gravity, and at the same time, the bottom is ventilated, so that the airflow enters the interior of the cylinder through the air inlet pipe at the bottom, and then an upward airflow is generated inside the cylinder, and a counterflow is formed with the gravity of the material. The material with a larger density is more affected by gravity, falls faster, can pass through the airflow layer faster to reach the bottom, and is discharged from the discharge pipe, while the material with a smaller density will be affected more by the airflow, rise and be discharged from the discharge pipe, and then the material with a smaller density will be affected by the airflow. In order to achieve efficient separation, a relatively uniform vertical airflow field can be formed in the cylinder through the design of bottom ventilation and top air outlet, which avoids the turbulence or unevenness of the airflow in local areas, and can make the airflow force on the materials at different positions relatively consistent, which is beneficial to improve the stability and repeatability of the sorting effect.

Under the action of the airflow, the elastic plate 42 is deformed by force, and at this time, extrusion is generated between the V-shaped plate 43 and the baffle 281. The baffle 281 rotates around the rotating rod 283. At the same time, there is extrusion between the positioning block 44 and the protrusion 282, so that the positioning block 44 drives the rotating rod 283 to slide downward inside the annular groove 285 through the protrusion 282, so that the baffle 281 coincides with the connection point with the discharge pipe 7, so that the airflow can be in a vertical state from bottom to top.

[0028] The material with lower density remains on the fixed ring 41. After the ventilation stops, the elastic plate 42 is reset, and the baffle 281 is reset. At this time, the motor 3 is connected to the external power supply and works. The motor 3 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the cylinder 46 to rotate, so that the cylinder 46 drives the cleaning plate 48 to clean the outer surface of the fixed ring 41, and the material with lower density is discharged through the discharge pipe 7.
