The poor invented the pesticide spraying machine from scrap

Seeing parents go out spraying pesticides in the field or tired, red limbs, Vu Tuan Thanh (11th grade, Hoa Lu A High School, Ninh Binh) developed the idea of ​​making automatic spraying machines to help relatives with hardship.

Poor student Vu Tuan Thanh has a small figure, wide forehead and always looks pensive. The capital of intelligent nature from a young age, male students Hoa Lu A High School charmed with scientific and technical innovation from grade 10.

The device is quite neat but works on many terrains thanks to the improved crawler set.(Photo: Phuong Vy).

Thanh's first project was a multi-purpose water sprayer that brought the first prize to the school and the second prize at the provincial level in the contest of Ninh Binh Youth Creation 2014-2015. From this water sprayer, Thanh improved into a pesticide sprayer instead of working in the field.

In order to have a passion for scientific creativity that does not affect learning and family work, Thanh arranged a reasonable schedule. In addition to school time, I help my parents with housework and look after their children. Most of the evening time Thanh spent designing detailed drawings for the products.

" In a month of drawing design, I have many times I lost sleep but the image of tired parents lying on the bed every time I went to spray pesticides, I urged him to complete the product as expected ", Thanh shared.

In December 2015, the complete design with many important details, superior to the old water sprayer like crawler instead of plastic wheels, instead of sprinklers and the " arm" system of the machine was also set. Flexible design like people to work more effectively.

All materials and materials used to manufacture pesticide sprayers include plastic pipes, pressure pumps, electric motors, 12v batteries, motorcycle cam crawlers, milo and 750 type milk bottles and jars. ml . purchased by Thanh in old car repair shops or discarded children's toys.

"Every time I have free time, I cycle to shops to buy or seek scrap materials. The equipment I find must be cheap but it must be good to be used for a long time , " Thanh said.

After two months of self-tinkering, in early 2016 my multi-purpose pesticide sprayer was born. The machine is 50 cm high, weighs about 3 kg with four main functions: moving, raising, lowering, extending the arms and reaching. The operation principle of the machine follows the remote control of the human with the left, right, arm movement and spraying buttons. Depending on the terrain of the parcel, the height of the crop that can adjust the nozzle of the machine. The use of crawler allows the machine to be able to move on any terrain.

" Each time spraying pesticides, the user just needs to mix and put in the bottle and then control the machine. The rest is done, so it is not affected to health , " Thanh said.

After successfully manufacturing the machine, Thanh ran the trial in the family's vegetable garden."What makes me happy in the first test run is that the machine runs smoothly, moves well into every vegetable bed to spray the medicine ", Thanh gladly shared and added his dream to have the capital to develop. products into pesticide sprayers can operate on large sample fields.

Automatic pesticide sprayers can replace people doing hazardous work.Although it is a semi-automatic machine, it works quite smoothly.(Photo: Phuong Vy).

"If I have capital, I will replicate the product model, mass production then sell to the market with cheap price for farmers to use. Just parents and farmers do not have to be poisoned every time they spray Pesticides are fun, no interest, " Thanh said.

Mr. Dang Thanh Cao, Secretary of Hoa Lu A High School said that the multi-purpose pesticide spraying machine is one of six outstanding products sent by the school to Ninh Binh province's Youth Innovation Contest this year. "This product has many unique creative points and high applicability, so I hope to bring great value prizes to the school and students ," Cao said.
