In this summer, the fire umbrella was high and Mai Lang was tumbling. In Jinzhuang Village, Linjiacun Town, Zhucheng City, Shandong Province, Xu Jinhua, a member of the Jinshan Agricultural Machinery Cooperative Agricultural Service Team, is driving a large combine harvester to stop wheat harvesting in this unseen wheat field.

Xu Jinhua sitting in the cab was calm, and the steering wheel of the harvester automatically adjusted the direction, as if he had long eyes, he could see the road and walk on his own, and the walking road was unusually straight, attracting a group of "old masters" Amazing.

People who know the line know that this harvester has a "smart brain"-Beidou navigation agricultural machinery automatic driving system, which can use the high-precision positioning information provided by satellites to complete automatic travel, automatic alignment, and automatic obstacle avoidance according to a predetermined path. operation. In the whole process, the driver only assists driving.

The combine harvester just drove by, and under the traction of Lovol M1204 tractor, a round bale baler followed to stop the baling operation. I saw that it opened its "big mouth", sucked the scattered wheat straw into the machine, and in a blink of an eye, "spit out" a round straw bale weighing about 250 kg.

"This guy is really good. He swallowed the straw into his belly and spit it out. He bundled it up. This year, our cooperative has ordered two sets of agricultural machinery purchase subsidies. We ordered two sets at a time, which can silage more than 7,000 acres. The wheat straw in the field can handle the feed problem of nearly a thousand cows. "Zang Jinshan, chairman of the Jinshan Agricultural Machinery Cooperative, said excitedly that this machine is worth buying!

At the end of the baler operation, a tractor with automatic driving technology pulled a 4-row air-suction precision seeder. "The surface of this machine looks rough, but it does precise work. Only one seed is sown in a hole, so seeds are saved, and no seedlings are needed." Zang Jinshan said.

"The corn seed sown by the machine only needs one grain per hole, is it okay?" Some farmers at the scene were a little bit "convinced", "the experience of growing the land for generations is two grains per hole."

"The air-suction seeder generates a negative pressure by a high-speed fan and transmits it to the vacuum chamber of the seed tray. When the seed tray rotates, it absorbs the seeds under the negative pressure of the vacuum chamber and rotates with the seed tray. When the seeds are transferred out After the vacuum chamber, the negative pressure is no longer accepted, and it falls into the ditch by its own weight or under the action of the seed scraper, and the seeding accuracy is greater than 98%. "Tai Muyun, senior engineer of Zhucheng Agricultural Machinery Service Center explained patiently.

Average seeding, different depths, uniform emergence, time-saving and labor-saving ...... Technologists listed many advantages of the air-suction precision seeder, and farmers on the scene gave thumbs up.

Zhao Daqing, director of Zhucheng Agricultural Machinery Service Center, said that as usual, smart agricultural machinery has gradually become the protagonist of the summer harvest, overturning people's impression of traditional agricultural consumption, "farmers are not busy" has become the norm, and mechanized agricultural consumption is becoming digital, intelligent, and precise. To accelerate.
