Development direction of rotary tiller

Column:Industry Information Time:2022-09-22
Develop to wide width high-speed rotary tiller. With the development of rice intensive and large-scale production, wide width high-speed rotary tiller for paddy field tillage and preparation will become the development direction.

1. Develop to wide width high-speed rotary tiller. With the development of rice intensive and large-scale production, wide width high-speed rotary tiller for paddy field tillage and preparation will become the development direction.

2. Develop towards joint operation unit. Large and medium-sized tractors have strong power output system, traction and suspension capacity, providing conditions for supporting dry land combined farming machinery. As a driving tillage machine, the rotary cultivator can easily complete the combined operations of stubble cutting, deep loosening, soil crushing, border making, ridging, furrowing, precision or semi precision sowing, deep application of chemical fertilizer, film laying, suppression and spraying by replacing or adding working parts, which can greatly improve the production efficiency and reduce the operating cost. The developed countries abroad have promoted the use of the combined operation unit with the arrangement and combination of operation procedures and the rotary cultivator as the main body, such as the universal rotary cultivator in Canada, the combined plow and rotary tillage seeder in Japan, etc.

3. Strategic development towards sustainable development. Reducing pollution and reusing resources has become the ultimate goal of current agricultural mechanization design. New models such as reverse stubble cleaning rotary cultivators that can complete straw returning operations will become an important research direction of rotary tillage machinery in the future. In addition, with the rapid development of modern science and technology, some new technologies will also be widely used on rotary cultivators, such as signal systems.

4. The demand for small rotary tillers has increased. With the development of greenhouse technology in China, the cultivation area of rural greenhouses is increasing. Due to the market demand, small rotary tillage machinery suitable for working in greenhouses has become a new focus of research.
