How does Combine Harvester Harvest Various Crops?

If you have personally peeled wheat, you know how difficult it is to remove the outer shell. And how is it possible for the harvester to complete the threshing of crops in the blink of an eye, which is more complete than manual peeling and grinding?

Firstly, the cutting platform at the forefront of the harvester is equipped with blades that can swing back and forth, responsible for accurately cutting the straw. Moreover, most cutting platforms come with hydraulic systems and sensors, which can automatically lift and level uneven fields without losing a single grain of grain. The crops that have been cut down will be pushed back by the reel and then gathered in the middle through the spiral conveyor devices on both sides. Afterwards, the wheat is fed into the threshing device of the harvester through the middle conveyor belt. This is the core part of the entire harvester.

After entering the threshing device, wheat will first be carried by the spiral structure at the front end and sent to the back. On the road, wheat will fall into the threshing drum. The drum rotates at high speed, constantly hitting the wheat like garlic, separating the grains from the shell. To avoid omissions, a grid plate is installed below the drum, and residual wheat will be squeezed and rubbed to further complete the threshing process.

These separated wheat grains will fall into the collector below through the grid plate. But at this moment, there are still many debris mixed inside. At this point, the two layers of sieves in the collector begin to work. The sieve keeps shaking to separate the debris. At the same time, on the left side of the sieve, there is a blower that can blow out high-speed airflow. The light and floating impurities are directly blown away, leaving behind heavy and clean wheat grains.

Finally, select the clean wheat grains and drop them back into the collection area at the bottom. Through a conveyor chain, enter the grain bin of the harvester. Then it is transported to the top grain outlet through the spiral drill installed in the grain silo.

Not only wheat, most combine harvesters can also harvest crops such as corn, soybeans, sunflowers, etc. Just replace the corresponding size of the cutting table, screen and other accessories. From bending down to wield a sickle to intelligent wheat harvesting, the harvester is truly an industrial miracle that rewrites the rules of farming
