The corn grain separator and creative student

Loving parents hard every season, Trinh Van Duc, student of class 12A5 Hau Loc 2 High School, Thanh Hoa, has built a continuous corn seeding machine that saves electricity and releases labor.

Continuous maize seed separator

This machine has brought to Germany the special prize of the 4th national youth youth creative contest (2007-2008).

When it came to the corn crop, the whole German family sat down and broke their backs to remove the seeds. Each corn pole, a handicapped person takes 2 - 3 days, the fingers are tired. Seeing that, Germany came up with the idea of ​​making a corn seeding machine to help his parents.

In fact, the corn grain separator on the market has existed for a long time, but it is not easy to buy such a machine with a pure agricultural family. A small capacity corn machine with the lowest price of VND 2 million. The large capacity is priced from VND 15-17 million. For 4 months, Germany has been trying to remove and install many times the corn machine 'dream'.

I learned AutoCad and made drawings on my computer, then went to buy materials and brought them to the welding workshop to hire workers to do my own. Realizing that the corn-based machines on the market have the disadvantages of consuming a lot of electricity, especially they often break corn and corn cobs due to the operation of the dam mechanism, Duc is determined to overcome this disadvantage. .

If the corn milling machine now uses square or pedal teeth to beat corn, causing grain and core breakage, then my machine uses a rotating batch, and on the lot there is dental welding like the type of scratching table, operating according to the mechanism seeds, make sure not to break the seeds and corn cobs. To save power, I used the 1.5kw motor.

With moving parts, take advantage of inertia to limit energy consumption. To make a corn pole, the machine will run for 15 minutes and only consume 40kW of electricity. According to German calculations, this power consumption is completely acceptable with the current rural electricity price of 650 dong / kw.

A special feature is that Germany has calculated so that the machine works continuously, not leaving the time between the corns to be reduced, wasting energy. 'This is the hardest part in making machines. How to calculate the time, the distance between the corns is not too cumbersome to jam the machine, not too long, leading to the loss of electricity ' - Germany explained.

There were many nights, Germany was awake to complete the machine. In return, I gave birth to a relatively complete product. 'If I calculate it, my device can sell for 2 - 3 million VND, with a capacity equivalent to a 17 million VND machine currently on the market' . - Germany smiled, said.

The creation of the 'young inventor', the practicality of the corn-beating machine has conquered the BGK of the 2008 National Youth and Youth Innovation Contest. The judging committee has awarded a special prize for this topic. and proposed to the World Patent Intellectual Property Organization.

Far away rumors, farmers in the village, many people in the province have asked to buy German corn machines.

The student is creative

Starting in the 8th grade, Germany participated in the national youth youth creative competition. Until now, I have 'collected' 2 second prizes, 1 consolation prize. The money earned from the prize, Germany bought books and a computer. Having just had a computer for a year, Germany has been exploring self-learning graphics software, designing and proficiently using AutoCad, Photoshop and 3D software.

Creative ham, Germany has created many items for family activities. The entire electrical network in the house is designed by Germany. I also built an alarm to prevent theft, 'but haven't tried it yet since the day of installing this system, the house hasn't been stolen yet'! - Germany laughs happily.

I also wrote the 3rd grade math software for my youngest little sister. On the season, Duc still helps in farming to help his parents. At leisure, the German 'profession' is to buy old computer equipment to restore and then sell.

'Earnings are enough for me to spend. But this year, 12th grade, so I put it aside, spend all my time studying. I have not thought about doing business in a corny machine, but if I have the opportunity to improve it so that everyone can use it widely, it will be fun. ' - Germany laughs back.

Also thanks to the machine to support parents, coming to Germany will be brought to Taiwan (China). 'I am planning to translate my entire topic report into English, turn it into a voice, print it on a CD, insert a 3D movie that I designed myself and bring this disc to perform at the competition' . - Germany said.
