Introduction

With the continuous improvement of efficiency and quality requirements of agricultural production, the improvement of farming tools has become one of the key factors to promote agricultural development. 

As a common tillage tool, the disk harrow is widely used in soil tillage, planting preparation and weed control. This paper will systematically discuss the historical development, technical evolution and application 

of disk harrow in modern agriculture.

1. Origin and early development of disk harrows

1.1 Origin of disk harrows

The prototype of the disk harrow can be traced back to the early period of human agricultural civilization, the initial farming tools are mainly made of wood and stone, simple structure and laborious operation. 

With the development of metallurgical technology, metal harrow gradually replaced the original wood and stone tools, which greatly improved the farming efficiency.

1.2 Early development of disc harrows

At the end of the 19th century, with the advancement of the Industrial Revolution, agricultural mechanization has been greatly developed. Disc harrows, as an important agricultural tool, have also begun to transition 

from hand tools to mechanized tools. The earliest mechanized disc harrows were drawn by horses or steam engines, and the material of the discs gradually evolved from cast iron to more durable steel.

2. Technological innovation of disc harrow

2.1 Structural characteristics of modern disc harrows

Modern disc harrows usually consist of a series of concave steel discs mounted on a common axis that rotate to cut and turn over soil as the tractor pulls. The diameter, Angle and number of discs are adjusted according 

to the soil type and tillage requirements to achieve the best tillage results.

2.2 Technical improvement and automation

In the second half of the 20th century, with the development of tractor technology, the design of the disc harrow also went through several improvements. Today's disc harrows can be equipped with a hydraulic system to

adjust the depth and Angle of the disc, and some disc harrows can be connected to a GPS system for automatic navigation and precise farming. These technological innovations have significantly improved the efficiency 

and precision of agricultural production.

2.3 Durability and environmental design

In recent years, as the requirements for agricultural sustainability have increased, the design of disc harrows has also tended to improve durability and reduce soil damage. The use of the new alloy disc not only improves the

 service life of the tool, but also reduces soil compaction during tillage through optimized design, maintaining the health and structure of the soil.

3. The application of disk harrow in modern agriculture

3.1 Soil cultivation

The disk harrow is mainly used in soil cultivation to turn the soil, break the soil and remove weeds. Its efficient cutting ability can effectively treat uncultivated land, bury organic matter such as stubble and weeds into the soil, 

and improve soil fertility.

3.2 Dryland and wetland farming

Disc harrows are widely used in both dry land and wetland farming. Especially in wetlands, disc harrows can effectively cut and turn over wet soil, avoiding soil clumping and crop root damage that can be caused by traditional 

tillage tools when operating in wetlands.

3.3 Integration with other agricultural machinery

In modern agriculture, the disc harrow is often used in combination with other machinery, such as in combination with a seeder for no-till seeding, or in combination with a fertilizer applicator for fertilizing while tilling. 

This combination of functions makes the agricultural production process more efficient.

4. the future development trend of disk harrows

4.1 Intelligent and data-driven

With the development of artificial intelligence and big data technology, future disc harrows may integrate more intelligent functions, such as automatic adjustment of tillage depth, real-time monitoring of soil conditions and

so on. In addition, by combining with the agricultural big data platform, the disc harrow can achieve more precise farming planning.

4.2 Environmentally friendly design

Future disc harrow designs will focus more on environmental protection and sustainability. For example, reducing carbon emissions during farming, optimizing disk angles to reduce damage to soil structure, and even developing

innovative tools that combine farming and ecological restoration.

4.3 Application of new materials

With the development of new materials science, future disc harrows may use lighter and more durable materials, further improving tool life and efficiency while reducing energy dependence.

conclusion

The development of the disc harrow shows the progress of agricultural mechanization and continuous innovation of technology. Modern disc harrows have not only significantly improved farming efficiency, 

but also taken important steps in intelligent and environmentally friendly design. Looking forward to the future, with the further development of science and technology, the disc harrow will play a more important 

role in agricultural production and provide strong support for achieving sustainable development of agriculture.
