Technical Field

The utility model relates to the technical field of breeding, in particular to a seed screening device for breeding.

Background Art

In order to ensure that crops can achieve high yield, stable yield, high quality and high efficiency of excellent genetic characteristics, it is necessary to use scientific breeding methods, combined with advanced technology, and use various instruments or processes to create genetic variation and improve genetic characteristics to cultivate new excellent plant varieties. In the process of large-scale breeding, such as seeds harvested after breeding, in order to facilitate subsequent processing of seeds, the seeds must be screened in advance to eliminate shriveled seeds and seeds with too small particles.

The prior art generally uses a vibrating filter to screen out seeds with too small particles, and uses the wind blown out by a fan to screen out shriveled seeds. However, when the existing seed screening device is used, when the fan blows air to screen the seeds, a small amount of seeds with qualified quality will be blown away, causing waste, and some shriveled seeds are mixed in the seeds and cannot be blown out, affecting the screening efficiency. Therefore, a seed screening device for breeding is proposed.

Since the vibration frame 3 and the mounting frame 2 are fixedly connected by the spring 16, when the vibration pump 10 is started, the vibration frame 3 will continue to vibrate, thereby driving the filter screen 4 to vibrate, and the seeds are introduced into the filter screen 4 through the discharge port 15 at the bottom of the guide trough 6. The seeds are filtered by the vibrating filter screen 4, and the seeds with too small particles are filtered out. At the same time, the fan 7 is started to blow air to the seeds on the filter screen 4. Since the vibration frame 3 and the filter screen 4 are inclined, the intact seeds can withstand the wind force blown by the fan 7 on the inclined surface, and the dust and empty shells of the seeds will be blown out in the process of the seeds being continuously turned over by the vibration, and finally the seeds of qualified quality are left, thereby completing the seed screening work.

The upper end of the vibration frame 3 is located on both sides of the filter screen 4 and is respectively fixedly connected with vertically arranged anti-leakage side plates 8 .

The leak-proof side plates 8 can ensure that the seeds will not scatter from both sides of the filter screen during the vibration of the filter screen 4.
