Seeds make the farmers' lifebloods and peasants get the benefits through seed breeding. Therefore, the quality assurance of seeds is of vital importance to farmers. In the process of seed quality inspection, there is a relatively large number of instruments used. That is, the electro-optical automatic particle counting instrument, which has a relatively large number of applications in the inspection of seed quality, is involved in the test of fullness of seeds and the moisture content of seeds.
Photoelectric automatic particle counting instrument is a kind of seed counting instrument. Its working principle is: dropping countless seeds into electromagnetic vibrating feeders, this instrument has two feeders, according to the seed particles. Size to choose to use, turn on the power. When the electromagnetic vibrating screw feeder is started, the seed moves along the spiral turn and finally falls through the seed-feeding mouth into the next kind of channel (light guide) of the photoelectric system and falls into the splice container. In the process of falling, each seed produces a projection on the light pipe, so that the light pipe immediately assumes a high resistance, and then an electric pulse is formed on the photoelectric counting circuit, which is amplified and reshaped to trigger the counting circuit. Automatically counts seed counts. When the number reaches a predetermined number, the automatic control circuit operates to cut off the power supply of the electromagnetic vibrating feeder, stops the seed feeding, and emits a corresponding instruction signal chirping sound. This completes an automatic grain counting operation and displays the seed. Number of grains. When the number of samples is less than the predetermined number of particles, the number of samples and the predetermined number are displayed on the display.
In the seed sample project, there is still one more used together, that is, the seed germination box. The seed germinating amount is partly due to the genetic problem of the seed, and the other part is the external environment, and the seed germination box is One can create a suitable environment for seed germination.
