A technology with independent intellectual property rights to manufacture thin films from fully degradable materials has recently taken place in Changzhou, Jiangsu. The technology has entered the production phase. According to relevant sources, today's environmental protection issues are not only the hot spots of the world's attention, but also become fashionable. The research on degradable plastics is in full swing. This technology is the latest scientific research achievement of Shanghai Jiao Tong University. This technology has two characteristics: First, the plastic film substitutes that are manufactured are completely degradable, that is, they will not cause any pollution to the environment; the second is the film's The raw material for manufacturing is corn starch, which has a low cost and therefore has a strong market competitiveness. Small machinery development of agricultural mechanization, improve work efficiency, improve agricultural production efficiency, in our such an agricultural country it is an important tool for the mower as an important role in agricultural production, has a direct impact on the yield of crops, its invention is a great progress of human civilization. Brush Cutter (Lawn mower), also known as weeding machine, grass cutter, grass trimmer is a kind of mechanical tools used to mow lawn, vegetation, etc., there are diesel engine and machine. It is composed of cutterhead, engine, walking wheel, walking mechanism, Blade, handrail, control and other parts. The output speed of the blade is greatly improved by using the high-speed rotation of the engine, which saves the working time of the weeding workers and reduces a lot of human resources. In the countries where the mechanization of animal husbandry is highly developed, the research on new mowers is developing in the direction of high speed and energy saving.
