Every minute, mechanic Nguyen Ngoc Tri's rice-sweeping machine can pick up a 70kg bag of rice, sweeping all the rice in its path.
In recent days, social networks in Phu Yen have been buzzing with the news that mechanic Nguyen Ngoc Tri (real name Ti, 36 years old, Hoa Tan Tay commune, Tay Hoa district) has successfully tested a rice harvesting machine that he invented himself.

I admire the mechanic
These past few days, Tri has been pushing the machine from his family’s mechanical workshop to the concrete road in front of his house, where his mother is drying rice from the fields that were harvested that morning. Tri pulls the cord to start the machine, then puts it into gear, and the machine slowly rolls over the drying rice. The metal screw in front of the rice rolls pushes the rice into the mouth of a 14cm cross-section tube. The rice is sucked up, separated into two funnels above, and flows into bags that are pinned to metal bars… There are no more rice grains left in the place where the machine passes because the plastic brush system installed behind the screw has swept it clean.
The machine has replaced manual labor such as raking, sweeping, scooping, and bagging. The machine only needs 2 people to operate: one person attaches the bag to the machine, lifts the full bag of rice from the machine and puts it on the ground, and the other person sews the mouth of the filled bag of rice. Every minute, Mr. Tri's machine can scoop up a bag of rice weighing about 70kg. He said that if 2 people join in replacing the empty bag and taking the full bag of rice out of the machine, they only need to increase the throttle to make the machine scoop up rice faster. This is the second afternoon that Mr. Tri has brought the rice scooping machine out for testing. Many curious people stood watching, admiring and praising.
“This mechanic is so good. The machine is really good, not only does it scoop up rice quickly but it also sweeps it cleanly. If I had one, I would hire one to scoop up rice to save time and effort,” said Mr. Tran Huu Bao, a local farmer.
Hope farmers have less hardship
Commenting on his own product, Tri said there are still some limitations such as the form is still rough, a bit big (1.5m long, 1.2m wide, 1.7m high), there is still a small rice field that the machine cannot fully suck up...
This young mechanic said that his family farmed 3 hectares of rice fields, and during harvest season, the amount of rice dried was very large, while the family was short of people, so it was quite difficult. Many local farming families also had difficulties, which prompted him to research and invent this rice-scraping machine. After graduating from intermediate vocational school of mechanics at Tuy Hoa Industrial College (now the Central College of Industry and Trade) in 2008, Tri returned to his hometown and opened a mechanical workshop, specializing in repairing plows, processing agricultural machinery, making agricultural tools... Although he had knowledge and experience, when he started making rice-scraping machines, Tri also failed quite a few times. At first, he used a Honda motorbike engine to do it, but the engine was too weak, unable to pull the suction and sweeping racks and help the rice-scraping machine move.
“I had to replace it with this 6.5CV gasoline engine to make it work. In addition, there were many other failures during the process, which had to be overcome many times. It took about a year to make the rice suction machine that is being tested today,” the mechanic confided.
According to Tri, he has only manufactured and tested this rice-picking machine, but has not yet calculated the total cost, how much gas the machine consumes per hour of operation, etc. "I am happy that the machine runs well, exactly as I expected when I manufactured it, but I have not calculated the cost yet," Tri laughed.
I made this machine for my family. If any villagers need it, I will lend it to them. If anyone wants to rent it, I will rent it to them. In the long run, if someone orders it, I will also consider making it, hoping it will help the villagers.
