Corn plucking machine of ethnic K

A K'Ho ethnic farmer, who had just finished 9th grade and never went to mechanical school, had been able to successfully improve the corn plucking machine, increasing labor productivity dozens of times compared to manual methods. The farmer was K'S Ha Ha, who lived in Village I, Da Sar commune, Lac Duong district, Lam Dong.

The town of Sar where K'Sá Ha Tang lives is a poor commune, self-sufficient economy is essential. Corn (corn) is the main food crop of the people here. There are about 500 households in the whole commune. Households who grow a lot each harvest a few hundred bushes, but it takes nearly a day's work to get a corn scoop by hand. This worried Ha Tang and set his own task: to create a tool to help family and relatives save time.

Once down in Duc Trong district, Ha Tang saw the corn-beating machine used by relatives here. However, according to him, this machine is limited in that: corn stalks are crushed, even a part of corn grain is broken due to the strong impact. In addition, this machine is too bulky, only used in flat terrain areas, convenient roads, but put into the hills of Da Sar is very difficult.

Although Ha Tang did not go to school and did not have the guidance of any officials and engineers, Ha Tang was determined to build the corn-powered machine as desired.

After three years of struggling with hundreds of removal, fitting and replacement devices, Ha Tang's joy broke in late 2003 when the corn plucking machine finished. The structure of this corn plucking machine is very simple: some rotary devices, belts and gears taken from rice thresher, corn-crushing device, propeller for sorting corn . All Attached and wrapped in a shell with very neat tole. The advantage of this machine is that it can use electric motor, oil-powered engine or manual rotation. The corn fruit, after being put into the machine (four fruits at a time), will be stripped separately, and the leprosy itself is not crushed. Time to pluck a corn in just about 5 minutes.

With this invention, K'Sá Ha Tang was selected by the Ministry of Science and Technology as one of the 15 "barefoot scientists" to attend the Vietnam Equipment Technology Market 2005.
