The shape resembles a marine tank, can cross the gully in the alpine hilly area, and can also “traverse†on the 35-degree slope... On September 17th, in the special science popularization “Science in the University†in Laoshan District, this one Less than a meter, the "little guy" who weighed about two hundred pounds, attracted everyone's attention. It is a self-propelled intelligent hot fog machine designed and developed by a group of post-graduate students in Anhui Agricultural University. The bottom is a crawler-type device. The front is equipped with a scanning sensor. It can effectively control high-stalk plant pests and diseases by spraying dense fog-like agricultural medicinal water. A labor efficiency of 15 people.
“High-stalk cropland, such as corn and sorghum, need to be sprayed with pesticides in the late plant protection period. It can walk quickly and play a good plant protection effect.†Zhu Cunxin, a graduate student of Anhui Agricultural University, who participated in the project, told the reporter. In the past, spraying pesticides on high-stalk crops was a difficult problem. Generally, it was artificial, and it also used drones. However, people carrying pesticides easily put pesticides on their bodies, which was not efficient, and the drones were widely sprayed and easily missed. It is also easily volatilized in the air.
Two years ago, under the guidance of the instructors of the College of Engineering, they developed the machine based on the actual conditions of the terrain and high-stalk crops. “The bottom is a crawler device that can travel on rugged terrain, and it sprays a dense mist of syrup on the bottom of the crop. The drug is transpiration upwards and covers a wide area.†Zhu Cunxi said.
In his view, high efficiency and low pollution are the advantages of this intelligent plant protection sprayer. In addition, the machine has significant intelligent features. It uses wireless network control and pesticide aerosolization technology. The wireless receiver can remotely monitor the thermal fog machine walking status and control agricultural atomization spray on corn, sorghum, etc. Comprehensive prevention and control of high-stalk crop pests and diseases. "The hot fog machine travels in the field at a speed of 0.1-1 m per second. One charge can prevent more than 80 mu." Zhu Cunxi said, "In the past, manual spraying was difficult, and one machine was equivalent to 15 people's work efficiency. Reduce labor costs while avoiding the health effects of drugs on workers."
At present, this machine has been repeatedly tested in the field, and has already experienced many battles. It has also been exhibited in exhibitions in Qingdao, Shandong and Shanghai. For more than two years, they have also made a second improvement to this hot fog machine according to the actual situation in the field, and will cooperate with local enterprises in mass production in the future.
Graduate students develop a smart spray machine with a top 15 working efficiency
[China Pharmaceutical Network Technology News] In agricultural operations, spraying high-stalk crops with pesticides is a difficult problem. Generally, it is artificially sprayed, and drones are also used. However, it is easy for people to carry pesticides on their bodies, which is not efficient. The drone sprays a wide area, is easy to miss, and is also volatile in the air.
