The 'barefoot' child invented a leaf blower

Do not eat to school, only "graduated" level 2, but farmer Dang Xuan Truong is the owner of the invention of rubber leaf scanner, to meet the cleaning needs of most households. Rubber farmers in Vu Hoa commune, Duc Linh district, Binh Thuan province.

Instead of running around to find people to sweep the leaves, or putting too much effort into clearing the leaves, farmers now just need to use a leaf fan invented by Mr. Truong to solve the problem. solve this problem. Where the fan is, the rubber leaf entangled there quickly. The device is quite simple, but the efficiency is great. Not only that, it also helps to reduce the risk of fire and explosion during the fall season.

Mr. Dang Xuan Truong said: People in his commune planted rubber a lot, often up to several hundred hectares. Therefore, every time when the rubber season is deciduous, every garden owner has a common concern about how to quickly collect leaves. Around November, December and on the days of Tet, the fallen leaves are almost all day long with very thick density, easy to catch fire, people have to sweep the leaves together in rows of rubber beds to prevent fire. This work is not heavy but it is very labor intensive because the leaves fall a lot, and after a few days of sweeping, it has to be re-scanned because of the dry season, the wind blows a lot.

In the past, Mr. Truong still scans the women 's leaves occasionally, so he understands this hardship.

During the sweep of rented leaves, Truong often thinks of a machine that can quickly scan these leaves. This thought clung to him for a long time. After that, he began tinkering with the lawn mower he still used for a long time, to conduct research. This lawn mower can clean up grass in beds, there are also gaps near gaps in rubber rows that growers still use as fire-resistant bumpers. Therefore, he thought that only the propeller would be able to scan the leaves.

He observed, disassembling the front lawn knife, then using the propeller attached. When booted, the machine also blows dry leaves, however, because the rotor is only made of plastic, less than an hour, the rotor has broken. Trusting in the structure of the machine can blow leaves. Mr. Truong continued to set up an iron propeller, to fit into a ready-made lawn mower. However, the iron propeller also failed because the wing was too heavy, the lawn mower did not rotate. Somewhat discouraged, but he did not give up, but continued to think, tinkering and decided to try the aluminum propeller. This time luckily smiled at Mr. Truong: the machine ran well and rolled the leaves into clusters. To have this propeller, he had to ask the mechanic of the mound in the district to help, the size of the propeller was about half a meter.

Simple improvement, great resources

With this "leaf blown" machine, it is possible to neatly scan 3 hectares of rubber garden in one day. Meanwhile, in the past, if you want to scan 1 ha of rubber, garden owners often have to hire up to three jobs and do it continuously in a day. Seeing the benefits that Truong's leaf scanner brings, people in the region are very excited.

The machine is rented by many garden owners for use because it can be cleaned faster than 5-6 times faster than before. Not only does it cover dry leaves in the upper layer of the face, but even the sticky leaves in the soil are caught up in the direction of the fan. The operator also only held a fan-propelled tree and stood up straight, without having to bend over as if scanning leaves with brooms.

The cost of producing a leaf blower is also very economical. It takes only 1 million VND to buy a lawn mower, and 50,000 VND for a propeller is able to use the machine for a while for both economic benefits and labor benefits. From the benefit of Mr. Truong's leaf blower, the people in the commune also imitated by improving the lawn mower of their home, to create a leaf blower. Mr. Truong also encourages everyone by communicating the experience he has done.

His improved experience is not only learned by relatives in the commune, but also to other regions. After that, Binh Thuan Rubber Company also sent staff to learn and learn the experience of this leaf blower. Dozens of leaf blowers have been put to use effectively in Duc Linh district (Binh Thuan).

Some people said that, because he did not know the registration of intellectual property to protect the rights to his invention, Mr. Truong suffered many disadvantages, leading to many people in the region and surrounding areas, imitate your product. However, Mr. Truong said, 'I think it's just a simple improvement of farmers, not big technical innovations, so I don't think about going to register this and that.'
