Students from the village school built a rice transplanting machine that surprised many people

During the follow-up to the field, the 8th grade pupil came up with the idea to create a rice transplanter to reduce labor for farmers.

Nguyen Duc Duong , class 8A, Tan Dan Town Secondary School , Yen Dung District (Bac Giang) is an impressive face at the 2009 National Contest for Young People and Children.

With the rice transplanting machine, this male student won 3rd prize in the competition."The idea came to my mind once I went to the field to see the rice transplanters. From the transplanter that people used before, I wanted to attach more electric motors, reducing the labor force for people.

The first person I shared the idea with was Mr. Nguyễn Đức Quỳnh (SN 1980), Junior High School Physics teacher, Tân Dân town. He praised the good idea and encouraged me to embark on it ".

The 8th grader started his idea by ordering components online, about 4 million. In the process of doing so, many times failed but teachers and students still did not give up.

From the time of drawing to the completion of the rice transplanting machine, the teachers and students took about 6 months with many details to edit many times.

"The hardest part was designing the remote controller. At first I planned to attach the motor to the machine, then control it manually. When operating the machine, people have to go with the machine in the field."

However, the teachers suggested that I should do automatic control so that people do not have to wade into the fields to control the machine, to avoid the cold in the winter.

I and Mr. Quỳnh contacted engineers of Việt Hân College (Bắc Giang) for advice on control ".

Currently, Duong's transplanter is controlled via smart phone software.

"In early summer of 2019, the machine was brought to the field for testing. For the first time, seedling was uneven and many trees were floating on the surface of the field. After that, the two teachers and students continued to pair 2 more pressing bars to push the land on both sides. in, keep the seedling still standing in the mud, avoiding the emergence of seedlings , " Duong said.

Duc Duong's rice transplanter made of iron consists of a number of main parts such as: machine frame, sliding table, galvanizing truss, conveying system, hand-in-hand . Solid machine structure, simple, compact, and heavy design Weight from 22-23 kg, easy to move in any terrain.

According to calculations, 1 minute transplanter has 120 clusters, 1 hour transplantable 180 m2 (ie 0.5 sao north), this capacity is equal to 6 people implanted manually. Transplanting 2 rows of rice at the same time, row density is 200 mm - 230 mm.

The machine has 2 seedling trays, and when farmers run out, they can feed the seedlings easily.

In particular, this machine 'scored' when it was rated as environmentally friendly due to not using fuel as gasoline, using electricity only via batteries.

"In addition to increasing productivity, the transplanter also implements rice in a straight line, more even and more beautiful than the human power , " said Duc Quynh, a companion with Duong.

"When listening to the students presenting their ideas, I found it very logical and feasible, so they were very supportive. After school, the two teachers and students spent time on this machine, sometimes after 12 pm, they still did not rest. " , the teacher shared.

He said that the production cost is about 10 million VND.

Teachers and students affirm, they will continue to improve and perfect the product

"After this, when put into mass production, the price of the product will fall. We will continue to improve and enhance this product," Mr. Quynh said.

Implementing from March to October 2019, Duc Duong and an automatic rice transplanter set out to take part in the National Youth and Children Creative Exam in the quite worried and pressured state of the student.

However, the product originated from the love for farmers helped convincing Bac Giang boys to win the third prize.

Although he won an award in Physics, Duong admitted that he was better at Mathematics and English. In addition to studying at school, reading, especially science books, is my special hobby.

Born into a family with a parent who is a teacher, Duong is strongly supported and supported by his parents with his ideas and creativity.

Ms. Nguyen Thi Kim, Principal of Tan An Secondary School, shared: "Duong is a good, hard-working student, who has been an excellent student for many years. Last year, she won the second and third prizes of the district's HSG English competitions and Math, he also won the National HSG Prize in English subjects. His personality is less talkative, quiet, likes to work, research tinkering about science ".

The Principal added: "With students passionate about scientific research, we advocate to support and encourage them to turn their creative ideas into reality. In addition to Duong, the students of the school also ever manufactured waste disposal machines, non-chemical shampoos, versatile agricultural machines . won prizes in competitions ".
