    1 national invention patent and 6 practical new type invention patents, and the spraying swath has reached 32 meters, the ground clearance reaches to 2.2 meters. An auto-walking high ground clearance spray rod sprayer showed the operation in wheat field of Xinhe town of Pingdu city of Qingdao recently. The manufacturing technologies of the sprayer are at the domestic leading level. It filled in the blank of plant protection of all-machine operation in agricultural production.

    “Auto-walking agricultural machine is a kind of agricultural machine that is self-powered and operated by drivers. It contains power device, gearing device, and walking and speed-changing device. We have spent 5 years on development, and eventually we got success.” The general manager of Qingdao Yitian Equipment that is the producer of the machine, Cui Xianglong, said with joy: “Take an example, in the past small sprayer is able to work in wheat field but is not able to work in paddy field; it is available for low plants such as bean but unavailable for high plant such as corn. Small equipment is low in efficiency but high in cost.” Cui said, the machine can be applied in the planting and harvesting of agricultural production, but it hardly can be applied in plant protection due to different conditions of dry and water fields and different height of plants.

    In order to enhance the accuracy of spraying fertilizer or pesticide by machine, Yitian also worked with a professional agricultural research institutes to make a set of Volume-fixed Accurate Spraying System. “In simple words, we can control the amount of fertilizer or pesticide, spraying amount will increase if the machine goes quickly, the amount will reduce if machine slows the speed. The amount for the plant can be controlled,” the technician of the company said. The application of the technology enables the auto-walking high ground clearance sprayer rod sprayer to be an effective tool in plant protection.
