AI Technical Summary

⚠Technical Problem

In existing rapeseed breeding devices, the seeds on the screen are difficult to remove, making it difficult to collect the retained seeds.

⚗Method used

A seed screening device is designed with an assembly mechanism for rapid separation mounted on the surface of the operating table. The screening frame is quickly separated and poured out by pushing the mechanism and the assembly mechanism, thereby reducing the seed screening time.

🎯Benefits of technology

It significantly reduces the time spent in the seed screening process, allowing operators to quickly separate the screening boxes and pour out the accumulated large seeds.

Abstract

The utility model relates to a seed screening device for rape breeding, including operation platform, and two screening frames of setting at operation platform top, the rape seed needing screening is poured into the screening frame above, wherein, the aperture in the screening frame above is greater than the screening frame aperture below, the screening frame above intercepts bigger seed, the screening frame below intercepts smaller seed, and the seed through the screening frame below falls into the deflector, through the rotation adjusting lever, wherein, the adjusting lever surface is installed with the thread in the mounting frame, the abutting disc of adjusting lever one end does not contact with the screening frame surface, can push the mounting frame upwards, makes the push rod slide on the sliding rod, can take out the screening frame, conveniently pours out the seed in the screening frame, through the drive motor driving the driving wheel rotation, and the driving wheel and the driven wheel are connected through the toothed belt, thereby driving the driven wheel and the rod body rotation, the rotation wheel on the rod body upper end and lower end all carry out rotation, and the sliding rod movement on the rotation wheel surface will drive the push rod swing.
