In order to save money riding a bicycle to buy materials, stay up late to squat 3D printing as parts, solve the problem of sandy grass pier ... Recently, a good news came from Wuhan Vocational and Technical College, Xu Fanao, the university's integrated electrical professional, Ji Chaoyang, Ni Yelan, Ding Fangzheng, Wang Rocky, and other five students, with the work "Saudi Kelxing", passed the five levels and chopped six generals, and won the first prize of the 10th National College Student Mechanical Innovation Design Contest of the "Solid Cup".

Create desert greening exclusive machine

Last year, when the team members learned about the game information, they began to ponder which projects to do. "This game is based on the theme of 'nature · harmony'. There are two directions of bionic technology and environmental governance to choose from. After the comprehensive team strength and reality, we choose the direction of environmental governance." During the survey, they learned about the harm of the desert to the environment and decided to make a breakthrough.

Considering the environmental impact of the desert on the northern cities, the team members decided to start with the sand after various investigations. Originally prepared to make a tree planting machine, I checked a lot of information on the Internet and found that the existing tree planting machine technology is very mature, and it is not meaningful to make it. So they turned their attention to the sandbarn laiding machine.

According to the team member Wang Ribo, the sand barrier is a barrier made of material made of wood, straw and other materials on the sand, so as to fix the flowing sand dunes to prevent sand from being blown away by the wind. If it is laid artificially, each person can only laid 8 to 13 acres per day, and the car with professional sand can only laid more than 50 acres. If you can design a wirelessly controlled automated mechanical sandpill barrier, then the efficiency of the sand barrier is doubled than the professional sandbood cars, and at least 120 acres of work can be paved in 8 hours.

Stay up late to go to the first prize

In order to produce high -efficiency sand barrier laying machines, the team members rushed to experiment. But during the experiment, they also encountered many difficulties. "Because the sand barrier is too heavy, the machine is too narrow when the machine is walking on the sand, and it is always easy to get stuck. We have tried several materials and kept trying to adjust the width before trying the track that will not be stuck." Wang Ribbo said that in addition to the incorrect weight of the machinery vehicle, the car's uneven weight caused the car to be prone to sand, and the team members could only constantly adjust the weight of the device. Not only that, because the distance between the material is too long, and the texture of the material is soft and easy to bend, the unsatisfactory production is not smooth. The team members have also thought of many methods to solve these problems one by one.

In fact, the birth of the "desert nemesis" is the result of team members and teachers staying up late in the laboratory. During the rematch, the team members changed three versions in response to the material warehouse. Among them, the second edition spent about 20 days, and the new parts were printed in 3D every day. The length of the printing is unstable. In order to complete it as soon as possible, the team members have been waiting for the results. Sometimes even wait until 3 am. After the printing is completed, take the experiment as soon as possible.

"The moment of success is very happy." The team members were pleased when they tried and error. Being able to achieve such a result is inseparable from the team. It is a process of suffering for team members during the preparation process. They all persist in the end, and the preparation process has also improved their practical ability and comprehensive quality.

Buy parts for one hour to save money

"These students are particularly sensible. They work hard in the laboratory. Sometimes they go out to buy materials." The team instructor Li Zhaohong said that the students not only stayed up late in order to catch up, but sometimes they need to purchase some small parts. They did not care about eating, ride a lot of bicycles on the big sun, and even reluctant to eat because the rice outside was more expensive than the school.

Seeing the students' struggle for their dreams, the teacher Wang Xiaoping was very moved. "These students really moved us very much. When they see their hard work, we are also trying to cooperate with them to run."

In addition to professional content, the competition also allows team students to learn a lot of new skills. "Because the competition needs to use 3D modeling, 3D printing, CAD sketching and other technologies, the teacher also trained for us before preparation. Because of the game, we learned a lot of new skills." Ding Fangzheng said that although he and the before the game, he and the The team members were very nervous, but the teacher's encouragement and everyone's efforts day and night made him overcome the tension before the game.

"Although there are strong enemies in the past and chasing troops in the back, everyone has to speak on the game. We cannot be inferior because the school is worse than others." After the results of the game came out, the team members were very happy because they had since they Work hard without any effort. Today, five members of the team have graduated with three members, and the remaining Ding Fang Zheng and Wang Rippo have also entered the junior. They hope to pass the promotion of this exam and continue to study in professionalism.
