Description

Technical Field

[0001] The present invention relates to the technical field of seed production equipment, and in particular to seed production equipment and technology for agricultural production. Background Art

[0002] Air separation, also known as airflow sorting, is based on the principle that solid waste particles with high density have high final settling velocity and move relatively close distance under the action of air flow, while solid waste particles with low density have low final settling velocity and move relatively far. This method is suitable for sorting solid waste particles with similar shapes and sizes. Sometimes, they can be crushed and screened before wind separation. Wind separation equipment is divided into three types according to the mainstream direction of the working airflow: horizontal, vertical and inclined. Among them, vertical airflow air separators are the most widely used.

[0003] In some seed processing plants, seeds of different particle sizes are screened, and vibration screening machines are more often used. The screened seeds are then taken out. For the bad seeds that are shriveled or have only skins left among the screened seeds, they need to be screened. Some are screened manually, which greatly reduces work efficiency and increases human resources. Some are screened by simple wind selection equipment, which has low work efficiency. The wind selection equipment and traditional screening machines are integrated, which increases the cost and also affects a certain degree of work efficiency.

[0004] The disclosure discloses a seed air selection device for agricultural production with publication number CN112058668B and a method for using the device, which comprises an air selection box, wherein the air selection box is composed of a feeding mechanism, a cleaning mechanism, an air selection mechanism and a cleaning mechanism, wherein the feeding mechanism comprises a feeding barrel, and the feeding barrel is fixedly connected to one end of the upper surface of the air selection box. The invention provides an air selection mechanism and an impurity removal mechanism in the air selection box, so that full seeds will fall off on sieves with different aperture densities, thereby screening out seeds of different particle sizes, while shriveled or bad seeds with only skins left will fall into a water tank in the flow of strong winds, which can not only play a screening role, but also play a dust-proof role, and is more conducive to production. Seeds of different sizes are quickly screened, so that the overall work efficiency is greatly improved. In addition, after some seeds that have not been screened in time fall into the return box, they continue to be air-selected, so as to ensure that the screened seeds have a higher usability, and can be screened cyclically, so that the success rate of seed screening is improved, and the practicability is higher.

[0005] The internal structure of the above scheme is relatively complex, which is not conducive to rapid operation and cannot achieve efficient wind selection operations, affecting the screening efficiency and quality of seeds, so it needs to be improved. Summary of the invention
