Description

Electric plant protection machine and its application

Technical field

The invention relates to the field of agricultural machinery, in particular to an electric plant protection machine and an application thereof.

Background technique

With the rapid development of science and technology, modern agriculture has got rid of the backward way of relying on manpower to cultivate. From the seeding, plant protection to harvesting, almost all rely on agricultural machinery and equipment to complete, the types and quantity of agricultural machinery are constantly improving, It is said that modern agriculture has entered the era of mechanization. Agricultural machinery has improved the agricultural production environment, reduced the labor intensity of farmers, improved production efficiency and land output rate, and achieved the goal of agricultural efficiency, grain production and farmers' income, but the mechanization of agriculture has improved agricultural production. While efficiency has brought great convenience to farmers, there is one problem that cannot be ignored. That is the pollution that agricultural machinery brings to the environment.

At present, the pollution caused by agricultural machinery is getting more and more serious. This is because the agricultural machinery currently used is mostly powered by diesel engines, which causes more exhaust gas. Because the particles in the exhaust gas are suspended in the air for a long time, it is easy to be human body. Absorption has a great impact on people and the environment. Secondly, due to operational problems, oil leakage, oil spills, etc., causing serious waste, pollution to water sources, land and crops, and even damage to crops are not conducive to building an environmentally friendly and friendly society.

As a kind of agricultural machinery, plant protection machine is an important part of agricultural and forestry production. It plays various preventive methods and positive effects for economic and effective plant protection, such as spraying water, spraying drugs, fertilizing, weeding, etc. Insects, grass damage and other harmful organisms are destroyed before the hazard. The use of plant protection machines is one of the important measures to ensure a bumper harvest of agriculture and forestry. Its application solves the problem of insufficient labor and improves agricultural production efficiency and agricultural precision. However, at present, most of the plant protection machines are equipped with diesel engines. The main components of the exhaust gas formed by combustion of combustible mixture (diesel and air) during the operation of diesel engines are mainly carbon dioxide, carbon monoxide, hydrocarbons, nitrogen oxides and carbon. Smoke particles, etc., these exhaust gases are discharged through the exhaust pipe, and then enter the air, causing damage to crops, causing pollution to the environment, and being seriously absorbed by the human body after harming the human body. When many plant protection machines work in thousands of households When the field is in the field, the pollution caused to the environment will be extremely serious and should not be underestimated. In particular, the current society is a society in which human beings and ecological harmony develop. The pollution problem of plant protection machines does not conform to the concept of modern green agriculture development, which is not conducive to the sustainable development of modern society and has attracted the attention of various departments.

How to coordinate the development of agricultural production and the environment is one of the themes that need to be paid attention to in the development of contemporary society. Therefore, agricultural machinery engineering urgently needs a new technological innovation to solve its pollution problem, so that it conforms to the concept of modern green agriculture development, and leaves a beautiful and rich environment for future generations. In this process, agricultural machinery manufacturers should take the initiative. This responsibility, production and production of more environmentally friendly equipment, through the application of more environmentally friendly equipment to reduce pollution of agricultural machinery, improve the economic benefits of agriculture, to promote the harmonious development of people and society. Therefore, in the context of both economic development and environmental protection, designing an environmentally friendly plant protection machine is an urgent problem to be solved in modern agriculture.
