Along with the continuation of the cutting disc 8, the corn comes to the cutting station, and the blade is fixed on the knife rest 4.7 and the extensibility of the blade can be adjusted to regulate the slice thickness. The corn tissue that falls after slicing is collected by the corn tissue collection rack 4.5 similar to the funnel, and is introduced into the sample inoculation tray 6.6 in the sorting part through the antistatic pipeline I. When the corn enters the next station, the track gradually descends to loosen the top column, and at the same time, under the pressure of the spring at the bottom of the seed cutting groove 4.13, the corn is put into the corn collection rack 4.8 at this station, and the antistatic pipe II is also introduced into the separator. The corresponding position of the corn inoculation plate 6.10 of the seed part, and at the same time trigger the light sensor to send a signal to the seed part. A pair of rubidium magnets are installed on the cover plate 10. When the compacting device 4.1 rotates to this position, the rollers of the compacting device 4.1 will be absorbed, and the compacting device 4.1 will return to the fully open state to prepare for compacting the next corn. Prepare. The sorting part is a planar motion mechanism controlled by four stepping motors. After receiving the signal from the cutting part, the motor starts working after a certain time delay to switch to the next station, and makes the two cutting discs The slots remain corresponding. Repeat this action to complete the entire seed cutting process.

What has been described above is only the preferred embodiment of the present invention.
