[0002] Seeds are the basis for a good harvest next year. When harvesting, seeds are often mixed with impurities such as straw, soil or dust, which affects the quality of seed purchase and subsequent seed sowing. Therefore, seeds need to be cleaned after harvest. Nowadays, there are many kinds of seed cleaning machines for seed cleaning. Chinese utility model patent CN2017211235419 discloses a seed cleaning machine, including a hopper, a spiral shaft, a spiral blade, and a bracket. The hopper is installed at the top of the spiral shaft, and the spiral blade is arranged around the spiral shaft. A drop-out port is provided on the hopper, and an adjustment plate is provided on the drop-out port. A fixed plate with an "L"-shaped cross section is provided on both sides of the drop-out port. The adjustment plate is inserted into the open cavity formed by the fixed plate and the hopper. The fixed plate with an "L"-shaped cross section includes a wide plate and a narrow plate, wherein the narrow plate is fixed to the hopper, and the wide plate of the "L"-shaped fixed plate is arranged parallel to the side of the hopper.

[0013] (1) The vibrating screen is configured to be detachable and installable. When cleaning seeds, the vibrating device drives the vibrating screen to vibrate, and the vibrating screen screens out large impurities such as straw and soil. Seeds and fine dust particles directly fall downward through the vibrating screen. Large impurities such as straw and soil move toward the lower side of the vibrating screen.

After cleaning, the vibrating screen is reinstalled on the upper part of the box body, or a new vibrating screen is directly replaced to ensure the quality of seed cleaning. The vibrating screen is easy to disassemble and assemble, clean and replace, and maintain;

[0014] (2) The pressure sensor is arranged at the first installation port for installing the vibration screen. The lower part of the higher side of the mesh of the vibration screen is pressed on the pressure sensor. Then, when the seeds fed through the feed hopper fall on the vibration screen, the mesh of the vibration screen applies the pressure generated by the weight of the seeds to the pressure sensor. The pressure sensor transmits the pressure signal to the controller. The controller controls the vibration power of the vibration device according to the pressure signal fed back by the pressure sensor, so as to better clean the seeds. The cleaning efficiency is high, the vibration self-adjustment can be realized, and the cleaning effect is good.

[0015] (3) The utility model is provided with a positive pressure fan and a negative pressure fan. When seeds and fine dust particles fall down through the vibrating screen, the positive pressure fan blows air to blow the dust to the side close to the negative pressure fan. The negative pressure fan works to quickly extract the dust and discharge it into the dust collection bag, which is convenient for collecting dust, further improving the seed cleaning quality, avoiding dust diffusion, preventing pollution of the working environment, and protecting the health of workers;

[0016] (4) After being cleaned by the vibrating screen, positive pressure fan and negative pressure fan, the seeds fall onto the seed collecting plate. The seed collecting plate is arranged at an angle, so the seeds slide rapidly along the seed collecting plate to the seed collecting port under the action of their own weight and directly slide into the seed collecting bag, which is conducive to seed bagging. In addition, the upper surface of the seed collecting plate is smooth, with low friction and sliding resistance. The seeds are not easy to get blocked when sliding down, and the wear is small.
