I.Foreword

1. With the development of science and technology and the advancement of agricultural modernization, the cultivated land machine has become an indispensable part of agricultural production.

Farmmachine can not only improve farming efficiency, but also reduce the labor intensity of farmers, improve the yield and quality of crops.

This paper will discuss the evolution process, working principle, advantages and disadvantages and future development trend of farmland machine.

II. The evolution of the cultivated machine The development of cultivated machines dates back to the early 20th century.

Initially, the arable machine was pulled by horses or manpower, but with the progress of mechanical technology, it gradually evolved to be driven by gasoline power.

With the popularization of electric motor and electronic control technology, the modern electric farmland tiller came into being.

III. the working principle of the machine The main working component of the tiller is the tool, which cuts the soil into uniform size when rotating at high speed.

At the same time, the plow on the plow opens the soil and exposes it to the air, which is conducive to the maintenance of water and the growth of seeds.

Some advanced arable land machines are also equipped with intelligent control systems that can automatically adjust the depth and speed of farming to meet the needs of different crops.

IV.the advantages and disadvantages of the machine 1. Advantages: farmland machine can improve tillage efficiency and reduce human labor; dig the soil and improve the water retention capacity and fertility of soil; reduce the labor intensity of farmers and improve the yield and quality of crops.

2. Disadvantages: the use of the machine needs certain skills and experience, improper operation may lead to excessive soil crushing or uneven tillage; at the same time, the noise of the machine is large, has a certain impact on the environment.

V. Future development trend With the continuous progress of science and technology, the future farmland will be more intelligent and efficient.

For example, automatic navigation and precision farming are possible by introducing advanced sensors and algorithms, reducing the environment with electric power, and using multiple tools and plows.

VI. Conclusion As an important tool of agricultural production, the development process and working principle of farmland machine are worth further discussion.

With the continuous progress of science and technology, the future of the farmland machine will be more intelligent and efficient, to bring more convenience and benefits to agricultural production.

At the same time, we should also pay attention to the environmental protection and sustainable development of farmland machines, in order to achieve the sustainable development of agricultural production 。
